[PATCH] Re: [Springframework-developer] custom XML config files

[<jas...@ma...>]

Agreed.

OK, its a trivial change but I've gone ahead and made a patch to allow 
application developers to reuse Spring's XmlBeanFactory to create 
custom application config files.

Colin,

You do have a point there. We coul use a prefix like "classpath*:" for =
loading all matching resources from the classpath. ("resources:" is too =
general, IMO: It's about multiple _classpath_ resources.) That would =
keep the behavior of "classpath:" in any case, and allow to explicitly =
specify "I want all matching resources" via "classpath*:".

Interestingly, a classpath resource string is the only resource location =
accepted by Spring's ResourceLoader that is not unique but can result in =
multiple matching files.

Betreff: Re: [Springframework-developer] Retrieve all class path =
resources with the same name



I've been thinking about this, and was wondering if it's appropriate
that _all_ matching resources are found, all the time, and also if we
should be worried about a backwards incompatible change.

Before, in ClassPathXmlApplicationContext, the locations
   beans.xml
and
   classpath:beans.xml
would return one resource, regardless of how many there were.

Now the former still returns one, while the latter returns 1-x.

Is it a problem that we've made a backwards incompatible change for the
latter form?
Is it a problem that somebody, if they want just one resource, has to
know that they need to use the first form? Additionally to this, this
distinction is possible when something like
ClassPathXmlApplicationContext, but for others that override the default
getResourceByPath to default to something else than a classpath
resource,  it's not a possibility.

I guess somebody could say, if there are multiple resources available
under that name, is it ever appropriate to return just one? I think so,
since after all, even in that case, the classloader resource loading
strategy is well defined and deterministic.

Since the 'classpath:' prefix is something we made up, why don't we keep
this for just a single resource, and use something like 'resources:' (or
whatever) to mean multiple resources?

RE: [Springframework-developer] custom XML config files

[Mason, R. <ros...@vi...>]

This would be really useful.  For applications that are constucted by =
spring it is much eaiser, quicker and less error prone to be working =
with a domain-specific config file with a dtd/xsd to describe/validate =
as you go.

XSLT is certainly one way of doing it. Either way, whether its some 
Java code that does the transformation, or XSLT the effect is the same 
- we get a shortened XML file (along with a custom DTD / XSD) for 
easier editing.

Personally I find XSLT to be a PITA so would rather a little simple bit 
of Java code to navigate over a DOM tree and turn elements into normal 
Spring XML but each to their own. So long as the hooks are there to 
easily modify the DOM before Spring starts to process it, folks could 
use Java code or XSLT to transform the DOM.

Given that the Spring implementation of CallbackFilter (Cglib2AopProxy) uses 
a hard-coded hashCode value of zero, it is quite expected generated classes
that differ only in the set of advised methods will have names with the
same hash code portion, and be differentiated only by the numeric suffix.
If you think that two generated classes with different suffixes should
actually be the same class, that would point to an incorrect implementation
of Cglib2AopProxy.equals. CGLIB uses the equals method of the
CallbackFilter, among other things, to determine if a generated class is
the same as another (i.e. whether a new one needs to be generated).

It might be simpler to split off the CallbackFilter portion of
Cglib2AopProxy into it's own class, even an inner class. This way you could
separate the equals implementations for AopProxy and CallbackFilter (if it
turns out they need to be different). Also, for performance, the hash code
of the CallbackFilter should eventually be changed to reflect the set of
methods being advised. I think Rod looked into doing this once but ran into
some test suite failures.

Depends how you want to plug it in.  Take a look at the ContextListener,
which created the initial applicationContext.  That might let you
specify the BeanFactory class, or would be easy to subclass.  You can
have multiple listeners start up, but I wouldn't know how to set one as
the parent of the other.

You can subclass the ContextServlet, and use the load ordering of
servlets to start each context.  Then, as the child is started, you can
look into the app scope, find the parent, and bind it up.

Should be possible,
Seth

[Springframework-developer] proposed refactorings of XmlViewResolver

[Seth L. <se...@eh...>]

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello,

I've implemented a XsltBeanFactory, which takes a XML doc + XSLT
stylesheet, and passes off the result to XmlBeanDefinitionReader.

As a first proof of concept, I am trying to implement a
XsltViewResolver.  I've created an optimized version of views.xml and a
stylesheet to convert it to the normal Beans DTD.

I'd like to propose a few refactorings to XmlViewResolver, to make it
easy to plug in different BeanFactories.

- - Possibly create a BeanFactoryViewResolver, with a protected method
createBeanFactory().  Subclasses can implement their own bean factory
here.  This method would be called by initBeanFactory(), which handles
all the caching operations (currently handled by XmlViewResolver's
initBeanFactory).

- - Either make location protected or add a getLocation() method.  This
would be on the XmlViewResolver, which would now subclass
BeanFactoryViewResolver.

- - a XsltViewResolver can then subclass XmlViewResolver, being able to
reuse the caching of the BeanFactory and the location property.

This is minor stuff, but making a BeanFactoryViewResolver might prove
useful as more and more BeanFactories are developed.

Thanks,
Seth

than:

<bean class="org.springframework.servlet.view.JstlView">

~    <value>/WEB-INF/jsp/foo.jsp</value>
~  </property>
</bean>

Other nice things about this is a DTD can be created for the shortened
version, to allow for validating and smoother XSLT.  Also, if others
need to extend the shorted form, they can either edit the XSLT file, or
better yet, just start writing spring BEANS elements.  The XSLT file
should just recognize the native spring beans elements and transfer them
over.

A XstlBeanFactory would do the trick there.  Given an XML file, and a
XSLT file, it should transform then delegate to XmlBeanFactory.

Ideas?  Thoughts?  This might be a good middle ground for those that
like XML and those that want to see the XML verbosity reduced somehow.

[Springframework-developer] custom XML config files

[<jas...@ma...>]

The Spring XML config file is cool and flexible; but for constrained 
problems it can be a little verbose. For certain scenarios I'd like to 
provide some neater, more concise XML syntax.

e.g. I'm considering configuring the ActiveMQ JMS message broker using 
Spring's configuration mechanism, but I'd prefer to be able to use some 
well defined aliases/macros in the config file - while preserving the 
full power of Spring's XML.

The basic idea is to use the default bean/property/value type syntax 
for Spring and add some context-specific macros (elements) which map 
directly onto specific well known bean factories - always allowing 
folks to drop down to the default Spring XML if they need to, so that 
we...

* reduce typing hugely
* to allow an XSD or DTD to be created to (i) validate the incoming XML 
and (ii) to auto-document the various properties available easily
* preserve the extensible & flexible nature of Spring's XML


This would be especially useful for configuring large services which 
want to have their own configuration mechanisms (like a message broker 
or other custom kinds of container). Having a little schema optimised 
for the problem space would really help


Here's an example of the kind of thing I mean, where we'd add a few new 
elements which the ActiveMQ-specific parser would understand...

<container name="foo">

     <!-- macros of some kind that ActiveMQ knows about -->
     <connector url="tcp://localhost:61616"/>
     <connector url="multicast://228.1.2.3.4:5000"/>

     <messageStore class="Foo">
	<!-- inside here drop down to Spring XML to customize some plugin -->
	<property name="cheese"><value>123</value></property>
     </messageStore>
</container>


Using the example above we could use a simple macro which turns

     <connector url="..." timeout="2000"/>

into

     <bean class="MyConnectorBean">
	<property name="url"><value>...</value></property>
	<property name="timeout"><value>2000</value></property>
     </bean>

This could be a trivial optional transformation step written in a 
little Java code, where the ActiveMQXmlBeanFactory could derive from 
the Spring XmlBeanFactory and install a custom transformer into the 
XmlBeanDefinitionReader so that any XML notation the ActiveMQ factory 
knew about could be transformed into normal Spring XML ready for Spring 
to do its thing.

I'm thinking the easiest way to do it could be to allow custom 
XmlBeanDefinitionReader implementations to be registered with an 
XmlBeanFactory via some constructor or protected method (e.g. either a 
setter method or create the XmlBeanDefinitionReader by lazy 
construction inside the XmlBeanFactory), then I could just provide my 
own custom XmlBeanDefinitionReader derivation which implements the 
macros I need - all used inside my own ActiveMQXmlBeanFactory which 
extends XmlBeanFactory.

I wondered if folks had tried this kinda thing yet? If folks agree - 
could we have the constructor or XmlBeanDefinitionReader setter/lazy 
create method on XmlBeanFactory please?

[Springframework-developer] MethodInvokingJobDetailFactoryBean supporting non-concurrent jobs

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

I've just committed a small (backward compatible) enhancement to the
MethodInvokingJobDetailFactoryBean that allows you to specify whether or
not method invoking jobs should be run in a concurrent fashion. By
default, if you register two triggers for the same job, the second will
start running if the first one hasn't finished.

You can now set MethodInvokinJobDetailFactoryBean.concurrent to false,
this will instantiate a Stateful job instead of a normal and stateless
Job, preventing jobs from interfering with eachother.

Additions to the documentation and the test suite have been done.

[Springframework-developer] Runtime.exec

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

I might have asked this before, but I currently face the problem again. =
Completely non-Spring, so off-topic ;-) If anyone can shed some light on =
this, I'd be very grateful.

Runtime.exec seems to have different behavior depending on the given =
"envp" parameter: If passed null, the new process will be a full child =
of the parent process, inheriting all its environment parameters and =
permissions. If passed a String array of environment parameters, the new =
process does *not* inherit the environment parameters and permissions of =
its parent.

Concretely, this causes an issue when running PHP via CGI within a =
servlet container: CGI requires to pass environment parameters to the =
new process, which causes the new process to not inherit the I/O =
permissions of its parent. As a consequence, the PHP process cannot open =
TCP connections, for example to a MySQL database...

A minimal example:

  Runtime.getRuntime().exec("php.exe test.php", null);

works, i.e. test.php can access the database.

  Runtime.getRuntime().exec("php.exe test.php", new String[0]);

does not work, i.e. test.php cannot access the database. Unfortunately, =
this variant is needed for invoking the PHP script via CGI.

[Springframework-developer] Retrieve all class path resources with the same name

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

FYI, I've just refined PathMatchingResourcePatternResolver to be able to =
retrieve all class path resources with the same name. It actually =
inherits this from the new base class ClassPathResourcePatternResolver.

http://sourceforge.net/forum/forum.php?thread_id=3D1096825&forum_id=3D250=
340

So "classpath:/beans.xml" will load all beans.xml files in classes =
directories or JAR files, if passed into =
PathMatchingResourcePatternResolver. Of course, Ant-style file path =
patterns like "/WEB-INF/*-context.xml" still work.

As this is automatically used by "contextConfigLocation" parameters, =
this means that we can specify such a URL for a root web application =
context, for example to auto-load all beans.xml files contained in =
deployed JAR files in WEB-INF\lib (HiveMind-style)!

I think HSQL is fine for the time being.

The discord with the autobuilds way of doing things is that right now 
for example the integration sample has its own JBoss config (needed to 
set up a DS for HSQL), whereas autobuilds expects to be the only thing 
setting up the server. Additionally, because cactus is used, the tests 
can be run directly in the project, instead of having to be part of the 
autobuild code. So I would like to modify the autobuilds stuff so that 
it can also run more 'self-sufficient' projects like this...

Colin, this would be great. If you manage to get it running using the
autobuilds, could you update me so I can try to add it to the 'nightly'
build? I don't know if you're planning to have other databases than just
MySQL/HSQL since that's the only one(s) I've got installed at the
moment.

I think the proposal sounds good. I think the point about 2 types of
interceptors is valid.

[Springframework-developer] Beginning of integration project checked in under autobuilds

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

I've checked in a preliminary version of a new project called 
'integration' under autobuilds. It is meant to eventually hold a bunch 
of integration tests which can not be covered by unit tests. I know that 
to some extent the petstore under there is for integration testing as 
well, but that does not necessarilly try to test specific functionality. 
I would ideally like to have full integration test converage somewhere 
for all classes not covered by unit tests. Currently, the only test in 
there right now is one for JbossNativeJdbcExtractor. Note that there is 
still a separate ejbtest project which is meant for ejb code. I did not 
add the test to the latter since I see the integrationtest project being 
used also for containers like TomCat. So most code should go into 
integration, and ejb specific code can go into ejbtest.

Neither 'integration' or 'ejbtest' are currently callable by the 
autobuilds functionality. They are cactus based (which is fine, it's 
actually more convenient than using httpunit), but for the former 
project there is some extra setup of the db and a few other things that 
needs to happen. I hope to spend some time in the relative near term to 
make them usable from autobuilds.

The more I think about this, the more I think it will be useful.  For
instance, I'd like to have the OpenSessionInViewInterceptor to apply to
everything (/*) where other Interceptors apply to certain Controllers.
I'm starting to get a proliferation of UrlHandlerMapping objects just to
map different combinations of Interceptors.

Jurgen, any more thoughts on this?  I might even implement this one soon
because it will greatly simplify things.

Thanks,
Seth

Hello,

After the removal of the jboss jars, the eclipse project files still
refer to jboss.jar and jboss-common-jdbc.jar.  Can someone with commit +
eclipse remove them from the Project Java Build Path?

Thanks!
