Betreff: [Springframework-developer] ParameterizableViewController




Hello,

in org.springframework.web.servlet.mvc the
ParameterizableViewController's handleRequestInternal method is
declared without a throws clause, though the overridden method from
AbstractController has a "throws Exception" clause. Regularly, after
subclassing ParameterizableViewController, I end up changing my code
because of the missing throws clause (e.g. because=20
RequestUtils.getRequiredIntParameter(),  used in the body, has a throws
clause).

Is there a reason, why handleRequestInternal in
ParameterizableViewController lacks the throws clause? Can it be
changed?


Regards,

Timo

Re: [Springframework-developer] Request and Session attributes in template based views

[<jue...@we...>]

Darren,

While I do agree with the argument that a Controller should be solely =
responsible for the exposed model, I see that there are valid exceptions =
to this rule. I wouldn't mind "exposeRequestAttributes", =
"exposeSessionAttributes" and possibly also =
"exposeServletContextAttributes" properties on an AbstractTemplateView =
base class, as long as they are turned off by default. As those flags =
are trivial to add, we could already do this for 1.0.2. What do others =

Betreff: [Springframework-developer] Request and Session attributes in =
template based views




A project of mine uses a servlet Filter to pre-process many http =
requests,
as a result of which objects are occasionally added to the user's
HttpSession or as request attributes.

I need these objects to be available in some views, regardless of which
controller eventually handled the request.  That's OK for JSP/JSTL and
even Spring's XSLT and Document based views that have access to them, =
but
awkward for Velocity/FreeMarker.  It's not difficult to extend these =
views
to cope, but I wondered if it would be better as an addition to the
framework classes.

Two new bean properties would exist on VelocityView (also applies to
FreeMarkerView so possibly in a new AbstractTemplateView below
AbstractUrlBasedView)...

private boolean exposeRequestAttributes =3D false;
private boolean exposeSessionAttributes =3D false;
// corresponding public mutators omitted

The rendering methods can then use these properties to decide whether to
put request/session objects into the velocityContext or FreeMarker =
model.

There's obviously a good argument that says the controller is solely
responsible for deciding what ends up in the model, but the following
issues arise in that case:
  i. If a view currently takes advantage of having access to the
request/session, then switching view technologies to a template view is
impossible without amending controller code or specifying a
HandlerInterceptor to expose the same objects.
  ii. If a HandlerInterceptor is not used (potentially awkward to
configure)  then all controllers would potentially have to be modified
to cater for the requirement.  A common app-specific superclass would be
impossible if the behaviour was required from both FormControllers and
SimpleControllers

Thoughts?

RE: [Springframework-developer] Pre-binding validation

[Daniel M. <mi...@pa...>]

Oliver,

This is a good idea. The object could even be evicted right after it is
loaded from the db. Then changes wouldn't persisted, even if the validation
logic were to perform an operation that involves a flush. When it is
determined that the submission is valid, saveOrUpdate will put it back into
the session and commit the changes.

I decided that my initial suggestion was not a very good one after thinking
about the potential complexity.

Thanks for the feedback.

In the event of validation failure couldn't you just rollback the
current transaction and start a new one for the rest of the request? Or,
even simpler, use Session.evict to make sure that it will never get
flushed.

[Springframework-developer] Defining a bean in one BeanFactory and configuring it in another

[Andy D. <an...@ma...>]

=2D----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I'm currently exploring different ideas for integrating SwiXML and Spring. =
=20
One such idea is to extend SwiXML's SwingEngine class to implement the=20
BeanFactory interface, which I've already done.  This works fairly well=20
conceptually, because SwiXML is very much like an IoC container: it can=20
create Swing controls, inject actions into them, and inject the controls in=
to=20
other controls.
I would like to use SwiXML to build my GUI, and Spring to configure and def=
ine=20
the behavior of the GUI.  What I would love to do is define (instantiate) t=
he=20
control in the SwiXML config, and configure it in the Spring config.  Is th=
is=20
possible?
Here is an example.  Say I have this SwiXML configuration (borrowed from=20
SwiXML docs):

<frame>
    <panel background=3D"6699cc" constraints=3D"BorderLayout.CENTER">
      <label text=3D"Hello Swinglet"/>
      <button name=3D"okButton" text=3D"OK" tooltiptext=3D"Press OK"/>
    </panel>
</frame>

Notice that I've named the button "okButton", which will make it appear in =
the=20
SwiXML BeanFactory as a bean with the id of "okButton".  Now, it would be=20
nice to wire that control with some behavior in Spring.  Maybe something=20
like:

<bean ref=3D"okButton">
  <!-- Set properties here -->
</bean>

This also lends itself to a clean separation of concerns.  A GUI designer c=
an=20
design the GUI without worrying about behavior, while a developer can wire=
=20
the GUI to his business logic.
Of course, there might be a better approach to this whole problem.  I'm ope=

to suggestions.

SDL looks really nice, but are some one have seen something more on SDL  
than that page?
May be some specs, some working code...
Author mention HiveMind beta5 but threre no such release on Apache site  
(last is beta 4).

I've used FMPP text preprocessor (uses FreeMarker) and there are such  
thing as
TDD - textual data definitions - which uses very similiar syntax and  
conventions.
Altough FMMP (and FM) has very nice integration with XML I have some spare  
time to play
with TDD - and it was much more "humane" than XML.

But there are one more thing - XML has DTD'd, Schemas and editors aware of  
all that stuff. So one can edit context.xml in IDEA and its still that  
verbose - but validated and have some nice popups that suggest required  
tags and attributes. And I can use any XML-aware tool to transform that  
definition to some form of easy-readable docs and reports (or even to SDL  
or TDD). And I actually do this with fmpp for hibernate descriptors and  
spring context definitions -> creating some nice html with clickable  
cross-references. Of course I can use XSLT or even tricky CSS to just  
present raw XML in browser. That is the actual power of XML. And this  
can't be done with SDL or some groovy script - although I can imagine some  
special adapter which produce SAX events or DOM tree from SDL or TDD - i  
can't imagine all problems with integration of that adapter them into all  
tools that one uses now. Of course we can easily generate text/xml but...
It's nice to use TDD in FMPP to quicky setup small data model - but all  
(may be just lazy ;) developers must understand that they rejectiong not  
only boring ugly parenthesises and quotes - they reject that power of XML.  
XML is not thad bad. It's matter of usage. We can make our old XML configs  
much less verbose and much more human-friendly with little modifications  
to format. I even have some propositions for spring:

<...><value>some_value</value></...>  change to just <...>some_value</...>

<bean ...><ref ...="some_name"/></bean>  change to just <bean  
ref="some_name"/>
<bean ...><ref ...="some_name"/></bean>  to  <bean ref="some_name"/>
or even
<property ...><bean ...><ref ...="some_name"/></bean></property >  to  
<bean ref="some_name"/>

and may be we can rework some parts of config to be not so  
machine-oriented.

(don't take me toooo seriuos, please, and forgive me my bad english 8)

That question I asked myself after pressing the "send" button ;)

I'll look at the BeanDefinitionReader, I think I'll write a hard-coded-java
solution first - now I'm making friends :p - and after that... I really
don't know yet. When I think of the "flow" of an application (I have a
procedural background) I like to visualize, I make a lot of drawings while
programming. Maybe a visual (couch) editor that generates the XML files.

Groovy, hmm.. interesting. Back to basic :) why not? 
SDL, it looks <emphasis>human readable</emphasis> to me!

I'm going to think about it when I'm on my holiday tomorrow in the beautiful
Toscana, Italia. Thanks for all the replies so far! I'm really excited,
programming is so much fun!

Re: [Springframework-developer] ApplicationContext without the use of XML

[Eduardo I. I. <zi...@su...>]

What about SDL? Its the HiveMind format. Its very clean, and as capable as XML 
(it don't support mixed content, but is not used in config files anyhow).

I would like to see Spring definition file in this format, I don't like to 
mentally parse the XML to find what is the real information. Some can say that 
it's laziness but it in everyday work it really makes a difference. I could use 
the saved "brain cycles" to something else ;)

It would not be difficult to create an XSLT to transform XML to SDL.

The SDL web site:
http://jakarta.apache.org/hivemind/sdl.html


And a good example from the site:

<?xml version="1.0"?>

<module id="some.module" version="1.0.0">
   <configuration id="ControlPipeline">
     <schema>
       <element name="processor">

          <attribute name="name" required="true"/>
          <attribute name="service-id" required="true"/>
          <attribute name="before"/>
          <attribute name="after"/>

          <conversion class="some.module.PipelineContribution">
            <map property="controlService" attribute="service-id" 
translator="service"/>
          </conversion>

       </element>
     </schema>
   </configuration>
</module>	

would become the SDL file:

module (id=some.module version="1.0.0")
{
   configuration (id=ControlPipeline)
   {
     schema
     {
       element (name=processor)
       {
         attribute (name=name required=true)
         attribute (name=service-id required=true)
         attribute (name=before)
         attribute (name=after)

         conversion (class=some.module.PipelineContribution)
         {
           map (property=controlService attribute=service-id translator=service)
         }
       }
     }
   }
}

RE: [Springframework-developer] ApplicationContext without the use of XML

[Alef A. <al...@jt...>]

Remco,

 

You shouldn't be writing your own AbstractApplicationContext. There are
BeanFactories and BeanDefinitionReaders. The BeanDefinitionReader is what
you should have a look at. There's XmlBeanDefinitionReader that reads XML
files and there is also a properties based reader.

 

Time is being spent on getting a Jython Beandefinitionreader in place, but
this won't be ready soon. Also, I've spent a bit of time on the
GroovyBeanDefinitionReader, but since Groovy is still a moving target, I've
postponed it a bit (also because of time limitations).

 

Have a look at the thread of about almost ago a week ago about alternative
methods to read bean definitions
(http://article.gmane.org/gmane.comp.java.springframework.user/1987 and then
click on the subject to see the thread).

 

Groet,

 

Alef

:-) Implement your own BeanDefinitionReader and do your own thing.

Seriously, we are looking for good ideas here from our users for more
out-of-the box options. Several Spring developers are thinking about this,
but user input is essential. Personally our XML works very well for me. But
our architecture allows more options and we want the best in 1.1, _as well_
as our XML format (of course). Groovy is a likely candidate and we're
probably going to work with James Strachan on that soon.

Our architecture actually allows _multiple_ config sources (even different
types) per BeanFactory... That may become more important with dynamic
reconfiguration in 1.1.

On stepping through the spring code:

public Connection getNativeConnectionFromStatement(Statement stmt) =
throws
          SQLException
{
        return stmt.getConnection();
}

stmt is of type com.mchange.v2.c3p0.impl.C3P0PooledConnection$2@1c63791

and stmt.getConnection() returns a C3P0ProxyConnection [Invocation =
Handler:
com.mchange.v2.c3p0.impl.C3P0PooledConnection$ProxyConnectionInvocationHa=
ndler@1d7aa64]
.

Therefore when you step through to the
OracleLobHandler.getOracleConnection(PreparedStatement ps) method, the
conToUse variable is set to com.mchange.v2.c3p0.impl.$Proxy0 which is =
not
assignable to oracle.jdbc.OracleConnection (resulting in an exception).

It seems like the c3p0 proxies are getting in the way.

We are using c3p0 version 8.4.2 and spring-rc1. Is there some trick we =
need
to be pulling here to get this working? Or perhaps create a
C3P0NativeJdbcExtractor to pull the connection from the c3p0 proxy?

Thanks,
Dave

[Springframework-developer] SimpleNativeJdbcExtractor support for c3p0

[David L. <da...@at...>]

Hi,

We're currently have an OracleLobHandler set to use the 
SimpleNativeJbdcExtractor bundled with spring. The comments on 
SimpleNativeJbdcExtractor say that it supports c3p0 out of the box but our 
current experience seems to say otherwise.

On stepping through the spring code:

public Connection getNativeConnectionFromStatement(Statement stmt) throws 
          SQLException
{
	return stmt.getConnection();
}

stmt is of type com.mchange.v2.c3p0.impl.C3P0PooledConnection$2@1c63791

and stmt.getConnection() returns a C3P0ProxyConnection [Invocation Handler: 
com.mchange.v2.c3p0.impl.C3P0PooledConnection$ProxyConnectionInvocationHandler@1d7aa64] 
.

Therefore when you step through to the 
OracleLobHandler.getOracleConnection(PreparedStatement ps) method, the 
conToUse variable is set to com.mchange.v2.c3p0.impl.$Proxy0 which is not 
assignable to oracle.jdbc.OracleConnection (resulting in an exception).

It seems like the c3p0 proxies are getting in the way.

We are using c3p0 version 8.4.2 and spring-rc1. Is there some trick we need 
to be pulling here to get this working? Or perhaps create a 
C3P0NativeJdbcExtractor to pull the connection from the c3p0 proxy?

Thanks,

[Springframework-developer] Log4jWebConfigurer behaviour

[Ben A. <ben...@ac...>]

Hi everyone

I was just wondering why Log4jWebConfigurer includes the
WebUtils.setWebAppRootSystemProperty(servletContext) line. AFAIK, it enables
properties such as ${webapp.root} to be used in log4j.properties. However,
as the JavaDocs explain, it conflicts in some containers (in my case Jetty)
unless an explicit "webAppRootKey" is specified for each webapp in web.xml.

This is a bit of a problem for those of us trying to deploy multiple web
applications in the same container for different clients, as we'd need to
generate a different web.xml for each (just to set the webAppRootKey to
something unique). I've spent a lot of time writing adapters and other
classes so client-specific properties can be held in the application context
and configured via PropertyPlaceholderConfigurer. It would therefore be
unfortunate to have to generate client-specific web.xml files, simply to set
a unique webAppRootKey.

To overcome the above, I've copied Log4jWebConfigurer and
Log4jConfigListener into a new package, simply commenting out the
WebUtils.setWebAppRootSystemProperty line. It seems to work, as I don't use
${webapp.root} in log4j.properties. I was therefore wondering if anyone has
any concerns with me providing a patch that skips over the
WebUtils.setWebAppRootSystemProperty if Log4jConfigListener detects an
initialization parameter named "log4jDoNotCreateWebAppRootSystemProperty"?

Cheers
Ben

Re: [Springframework-developer] OracleOCIConnectionPoolDataSource: DataSource implementation for Oracle proxy connections

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

Guido,

Thanks for taking the time to put this together.  From a brief look it looks
like an excellent solution.  I'm hoping to be able to try it out fairly soon
and I would also like to see it tested in an app server environment and with
Hibernate.  If you or anybody else get a chance to test it further, please keep
us posted.

Thanks,

Thomas Risberg

Re: [Springframework-developer] Turning off autocommit in JBoss / Oracle datasource

[Rod J. <rod...@in...>]

Would be cool but when I last looked at it over a year ago it was scary
stuff. If anyone can do it, we can. Might be good to see how many people
want it... I would probably use it from time to time. Not too often though.

Re: [Springframework-developer] Turning off autocommit in JBoss / Oracle datasource

[Dmitriy K. <dko...@ru...>]

BTW, is there a possibility to create an abstraction for Oracle XMLType 
so the application code wouldn't have to deal with the low level JDBC 
code? Kinda like LOB support.

Thomas, Juergen?
