Re: [Springframework-developer] customized BeanFactory

[Steven D. <ste...@in...>]

Bing,

You can implement a BeanFactoryPostProcessor to do that. Have a look  
at the code of PropertyPlaceholderConfigurer. This class inspects  
bean definitions and replaces ${key} with property values loaded from  
property files. BeanFactoryPostProcessors are recognized by the bean  
factory and applied automatically.

Re: [Springframework-developer] new feature proposal for SWF: asynchronous flows

[Erwin V. <erw...@er...>]

We already have asynchronous flows: you can start any number of top-level 
flow executions concurrently.

So what exactly is the benefit of the additional support you describe? Why 
can't you just use a subflow or a second independent top-level flow for 
those 'mini wizards' you describe? I'm not sure all the added complexity 
really pays off...

Stuff like "When the view state of the parent transitions the flow 
executions of the asynchronous flows are terminated. The FlowAttributeMapper 
can be used in the same way as with sub states to  map scope attributes 
between a parent flow and asynchronous flows." and "In this scenario it may 
be desirable to allow an end state of an  asynchronous flow to trigger the 
transition of the view state of the parent" is a bit strange IMHO: if you 
want that kind of stuff, just use subflows and a flow execution listener.

Also, it seems that terminating all started asynchronous flows when the 
'parent' transitions could lead to a number of issues. What if a client 
spawned multiple ansynchronous flows and one triggers a transition in the 
parent. As a result all those 'mini wizards' would become unusable...

[Springframework-developer] customized BeanFactory

[Bing R. <br...@cc...>]

I'm implementing my own BeanFactory as a subclass of
DefaultListableBeanFactory. What I want to do is to reinterpret injected
values on a bean, such as the <value>#{param.userName}</value> part in the
bean definition: 

<bean ...>
  <property name="a"> <value>#{param.userName}</value></property>
</bean>

I'd like to set the value from another source (such as in JSF context) at
the time the bean is instantiated. Any tips how my code can get a chance to
re-interpret the dependency?

Thanks!

[Springframework-developer] new feature proposal for SWF: asynchronous flows

[Steven D. <ste...@in...>]

Guys,

I've skyped with Keith today about a new feature I would like to see  
added to SWF: asynchronous flows (useful with AJAX technology).

Asynchronous flows are normal SWF flows that are launched  
asynchronously from a view state, typically thru AJAX calls, separate  
browser windows or frames.

An asynchronous flow is thus a flow definition that is started  
through an event id that's defined in a view state:

<view-state id="myViewState" view="myView">
     <transition on="submit" to="myActionState"/>
     <async-flow on="myAsyncEvent" flow="myAsyncFlow"/>
</view-state>

When an asynchronous flow is launched the parent flow execution is  
not transitioned. Asynchronous events are accessible through the flow  
execution id of the parent. When an asynchronous flow has been  
started a new flow execution is created and that flow execution is  
referenced to by a new flow execution id. This allows for multiple  
invocations of the same asynchronous flow by the same client. When an  
asynchronous flow execution ends it can trigger the transition of the  
parent view state (more on that later).

Otherwise asynchronous flows have the exact same behavior of normal  
SWF flows. They can have action states, view states, subflow states  
and decision states. When the view state of the parent transitions  
the flow executions of the asynchronous flows are terminated. The  
FlowAttributeMapper can be used in the same way as with sub states to  
map scope attributes between a parent flow and asynchronous flows.

A typical use case for an asynchronous flow is a mini-wizard  
contained as a widget in a view. The asynchronous flow is launched by  
an AJAX client-side HTTP component that replaces the inner html of a  
div tag with the html send back by the view states of the  
asynchronous flow (a normal JSP views for example). We probably need  
a JSP tag that renders the client-side JavaScript:

<ajax:sendRequest eventId="myMiniEvent" flowExecutionId="$ 
{flowExecutionId}"/>

This JSP tag can than be used in the views of asynchronous flows to  
mimic browser behaviour. This feature could make creating mini- 
wizards child's play. It should be noted that when the view is shown  
by the browser and the JavaScript code of the JSP tag kicks it will  
immediately launch a call to the asynchronous event. A optimization  
could be to let this JSP tag execute the call to asynchronous flow on  
the server if that's feasible.

An example of a AJAX mini-wizard is a section on the site of a travel  
booking agent where:

  - your can enter a departure and destination city on the first page
  - next a page to confirm the names of the cities
  - then a page to select the dates of departure and return and
  - then a page with a list of available flights

In this scenario it may be desirable to allow an end state of an  
asynchronous flow to trigger the transition of the view state of the  
parent, for example when a flight in the mini-wizard is clicked on.  
Since the flow execution of the mini-flow only knows its own flow  
execution id the id of the parent cannot be used. For this scenario  
we could use the name of the asynchronous flow + the name of the end  
state as the event name of a transition on the parent view state:

<view state ...>
    <async-flow on="myAsyncEvent" flow="myAsyncFlow"/>
    <transition on="myAsyncFlow.myEndState" to="myNextState"/>
</view-state>

Mini-wizards can also be displayed in a pop up browser window when  
selecting items to complete a form, for example to select products in  
an order form. These mini-wizards obviously also can be implemented  
as AJAX mini-wizards.

Any thoughts?

Re: [Springframework-developer] webflow scoped bean definitions

[Colin S. <col...@ex...>]

That's the exact question I thought of when I saw your blog post last 
night.

You are supposed to be able to include one DTD in another. I've never 
really done it myself, but it looks basically to be very similar to how 
you include one XML fragment in another:

<!ENTITY % mylists SYSTEM "dtds/listfrag.ent">
...
%mylists;

or

<!ELEMENT combo (A, X)>
<!ENTITY % dtd_start SYSTEM "http://www.foo.com/start.dtd">
<!ENTITY % dtd_end SYSTEM "http://www.foo.com/end.dtd">
%dtd_start;
%dtd_end;

[Springframework-developer] webflow scoped bean definitions

[Keith D. <ke...@in...>]

I've described a significant new feature for enhancing the modularity of a
SWF webflow definition here:
http://www.jroller.com/page/kdonald?entry=web_flows_as_application_modules

 

I've already committed this enhancement to CVS head and the sellItem sample
code has been updated to demonstrate it.

 

There is only one issue with the enhancement, and I'd like feedback on it: I
had to temporarily turn of XML dtd validation of spring-webflow.dtd as I saw
no way to easily import spring-beans.dtd to allow for webflow-scoped bean
definitions.  In fact, with DTD-based validation the only approach I can see
for allowing bean definitions within a webflow definition is just to
duplicate the spring-beans.dtd elements in spring-webflow.dtd.

 

Does anyone know a better way? It's not the end of the world if there is
some dtd duplication to support validation and code completion, but I'd
obviously like to avoid it if possible.

 

Thanks,

 

Keith

If you're using JSP 2.0, you can use the following tag files.  The  
issue has quite a few votes (21!), so hopefully it'll be in the next  
major release.

[Springframework-developer] Spring MVC and equivalent to HTML tags (and validation)

[Paul S. <tk...@tk...>]

I guess I'm not doing a good job of staying a lurker. :)  

First a follow up on validation.  Although spring module's commons
validator integration did not have any documentation, it's used in
Appfuse.  So Appfuse acts as a sample example I can use to get the
integration going.  

The other piece that Spring MVC seems to be missing is the equivalent to
Struts HTML tags.  I see people posting as recently as 4 days ago asking
about this, so I know I'm not the only one.
(http://forum.springframework.org/viewtopic.php?t=8906)

Is there any plan for taglibs like Struts HTML?  I looked back at my old
Struts JSP files and those taglibs were a gigantic value add.  I'd
definitely be willing to work on that.  I have a feeling I may not be
alone on that.

Thanks to all for responding so quickly.  I was finally able to build spring

Thanks again all.

Re: [Springframework-developer] New JDBC feature - named parameters

[Thomas R. <tho...@tr...>]

James,

I've been off for a few days so little progress on this feature  
recently - just pulled the code out of the main tree.  The code will  
make it's way back after 1.2.5 is out - might add it to the sandbox  
in the meantime.

I did not think of adding support for pulling data directly from a  
bean - but the more I think about it the more attractive this option  
seems.  There has to be some parts of Spring that can be reused for  
pulling property values from a bean :)

For the expanded list - I do use the placeholder/bind variable  
approach so no need to worry.  The primary issue will be problems  
with very long lists - different drivers/databases have different  
limits on how long the list can be.

Thomas

PS - I'm not insulted :)  It's always better to bring up issues while  
something is still being worked instead of afterwards.

[Springframework-developer] Preparing for release 1.2.5

[Juergen H. <ju...@in...>]

All,

We are now starting to prepare release 1.2.5. The actual release is
scheduled for the end of this week, but we are approaching an enhancement
freeze as early as tomorrow. Afterwards, only bug fixes are expected until
the actual 1.2.5 release.

Consider the upcoming nightly snapshots as 1.2.5 release candidates: Please
give them a try and report any last-minute issues you might encounter!

Re: [Springframework-developer] Replacing EBJs with Spring suggestions

[Michael E. M. <mm...@re...>]

Scalability and failover is crucial..
Thats why all my business logic is completely stateless, behind network 
hardware
that handles that scaling/failover.
I don't like stateless EJBs for many reasons, but mainly because of the 
threading model it specifies.. which promotes
the use of code that is not thread safe and hense non-portable outside 
oof an EJB container.
The whole thread pooling mechanism in EJB is something we simply don't 
need any longer.

There's a section in "Hibernate In Action" that has a teriffic  
indictment of entity beans..
CMP was a specification dejour in my opinion. a huge mismatch for OOP/OOD.
maybe CMP 3.0 will help... heh.

1.3.4 Considering EJB entity beans

In recent years, Enterprise JavaBeans (EJBs) have been a recommended way 
of persisting data.  If you've been working in the field of Java 
enterprise applications, you've probably worked with EJBs and entity 
beans in particular.  If you haven't, don't worry -- entity beans are 
rapidly declining in popularity.  (Many of the developer concerns will 
be addressed in the new EJB 3.0 specification, however.)

Entity beans (in the current EJB 2.1 specification) are interesting 
because, in contrast to the other solutions mentioned here, they were 
created entirely by committee.  The other solutions (the DAO pattern, 
serialization, and ORM) were distilled from many years of experience; 
they represent approaches that have stood the test of time.  
Unsurprisingly, perhaps, EJB 2.1 entity beans have been a disaster in 
practice.  Design flaws in the EJB specification prevent bean-managed 
persistence (BMP) entity beans from performing efficiently.  A 
marginally more acceptable solution is container-managed persistence 
(CMP), at least since some glaring deficiencies of the EJB 1.1 
specification were rectified.

Nevertheless, CMP doesn't represent a solution to the object/relational 
mismatch.  Here are six reasons why:

    * CMP beans are defined in one-to-one correspondence to the tables
      of the relational model.  Thus, they're too coarse grained; they
      may not take advantage of Java's rich typing.  In a sense, CMP
      forces your domain model into the normal form.
    * On the other hand, CMP beans are also too fine grained to realize
      the stated goal of EJB: the definition of reusable software
      components.  A reusable component should be a *very*
      coarse-grained object, with an external interface that is stable
      in the face of small changes to the database schema.  (Yes, we
      really did just claim that CMP entity beans are both too fine
      grained and to coarse grained!)
    * Although EJBs may take advantage of implementation inheritance ,
      entity beans don't support polymorphic associations and queries,
      one of the defining features of "true" ORM.
    * Entity beans, despite the stated goal of the EJB specification,
      aren't portable in practice.  Capabilities of CMP engines vary
      wildly between vendors, and the mapping meta-data is
      vendor-specific.  Some projects have chosen Hibernate for the
      simple reason that Hibernate applications are more portable
      between application servers.
    * Entity beans aren't serializable.  We find that we must define
      additional data transfer objects (DTOs, also called value objects)
      when we need to transport data to a remote client tier.  The use
      of fine-grained method calls from the client to a remote entity
      bean instance is not scalable: DTO's provide a way of batching
      remote data access.  The DTO pattern results in the growth of
      parallel class hierarchies, which each entity of the domain model
      is represented as both an entity bean and a DTO.
    * EJB is an intrusive model: it mandates an unnatural Java style and
      makes reuse of code outside a specific container extremely
      difficult.  This is a huge barrier to unit test driven development
      (TDD).  It even causes problems in applications that require batch
      processing or other offline functions.

We won't spend more time discussing the pros and cons of EJB 2.1 entity 
beans.  After looking at their persistence capabilities, we've come to 
the conclusion that they aren't suitable for a full object mapping.  
We'll see what the new EJB 3.0 specification can improve.

Re: [Springframework-developer] Replacing EBJs with Spring suggestions

[Eugene K. <eu...@md...>]

Michael,

   It seems that your position is quite extreme. :-)

   I wouldn't say that CMP is a mess. There are use cases for CMP's, 
thet perform quite well and would provide transactionality and caching 
(especially in a clustered environment).

   Besides cross-server transactionality, J2EE appservers provide a 
good deal of clustering, connection pooling (JDBC, JMS, JCA), 
security, remoting (RMI-IOOP) and other common services that would be 
just sily to reinvent. I'd say it makes a lot of sense to use those 
services when adding Spring's value into existing J2EE/EJB-based 
applications.

   regards,
   Eugene

[Springframework-developer] Spring WebFlow production release date.

[Themba M. <The...@di...>]

Hi;

=20

I would like to know when will Spring FlowFlow have a production
release. The thing is, I need it for some of our application but I
cannot get a sign off as it is still a preview.

Re: [Springframework-developer] How the heck do you build Spring!?

[Thomas R. <tho...@tr...>]

Forgot to mention that maven.xml is maintained but there is sometimes  
a lag when new features are added to the build.  We all use ant  
during development.

Re: [Springframework-developer] How the heck do you build Spring!?

[Thomas R. <tho...@tr...>]

Billy,

It's a standard Ant build.  Run "ant -p" to get a list of all the  
targets.  There is also a build.bat that can give you an idea of what  
is needed.

I usually run "ant clean build tests" and "ant fulljar".

Thomas

Re: [Springframework-developer] How the heck do you build Spring!?

[Dave B. <dbr...@qi...>]

type

maven

in the directory where the maven.xml file is.

Or you can type

maven -h

for help

or type

maven -g

for all the goals (build targets)

(this all assumes of course, that you have maven installed)

[Springframework-developer] How the heck do you build Spring!?

[Billy A. <bil...@ho...>]

Greetings,

I am new to the Spring Framework.  I have looked at the reference 
documentation, as well as a number of books, and I have yet to see how to 
build spring after downloading it.  I see a maven.xml file, so I assume that 
it is a maven build.  Could someone point me to directions for the initial 
spring build?

Thanks in advance

- Billy

Re: [Springframework-developer] Replacing EBJs with Spring suggestions

[Michael E. M. <mm...@re...>]

Start by reading Rod Johnson's book on J2EE development without EJB.  
http://www.springframework.org/node/23
There are some merits for using EJB, but in almost every single case I 
have seen, you don't need them.

EJB Entity Beans (CMP) is a huge mess; don't use them.
EJB containers provide distributed transaction capability; a business 
transaction can span
multiple servers.. but I would try my very hardest not to introduce that 
kind of tight coupling.

I'm in the process of moving a Weblogic EJB application to Spring/Hibernate.
I'm almost done.
The new product is less than 1/2 the code size (including config files.. 
like the entity bean descriptors) and it runs about 40% faster. 
All business logic is located in classes that depend upon nothing but 
J2SE.. just
plain old java objects.. 
I can run/test the application stand alone, as a SOAP service, as an RMI 
service.. all I do is change a property file entry to do the switch.  I 
can emulate dowstream services (stup them out)
by swapping in a test stub in the Spring configuration.
I can do all my database persistence with a single graph of java objects.
Hibernate persists the graph according to my Spring transaction 
demarcations.

Just for the fun of it, I wrapped my business POJOs with Spring's EJB 
abstraction,
and deployed the application on JBoss.  NO PROBLEMS!!!

Re: [Springframework-developer] Replacing EBJs with Spring suggestions

[Eugene K. <eu...@pl...>]

Paul,

  You can choose one of the Spring remoting options if 2nd application 
live on another domain. But I'd rather stay with remote EJB facades in 
this situation to take the best parts from both Spring and J2EE. See my 
blog post at 
http://dev2dev.bea.com/blog/euxx/archive/2005/08/implementing_j2.html

  regards,
  Eugene
