problem with SimpleRemoteStatelessSessionProxyFactoryBean

[ElPapa]

I'm seeing this error in my servlet's applicationContext.xml when I try to initialize access to a remote EJB. I'm figuring I'm probably just not doing this correctly. Can someone point to an example on this? I'm using JBoss 3.2.3 - Thanks much.

org.springframework.beans.factory.BeanDefinitionSt oreException: Error registering bean with name 'myComponent' defined in resource [/WEB-INF/applicationContext.xml] of ServletContext: Bean class [org.springframework.ejb.access.SimpleRemoteStatele ssSessionProxyFactoryBean] not found; nested exception is java.lang.ClassNotFoundException: org.springframework.ejb.access.SimpleRemoteStatele ssSessionProxyFactoryBean

java.lang.ClassNotFoundException: org.springframework.ejb.access.SimpleRemoteStatele ssSessionProxyFactoryBean

exception is java.lang.ClassNotFoundException: org.springframework.ejb.access.SimpleRemoteStatele ssSessionProxyFactoryBean

What spring jar files are you using in your class path?

SimpleRemoteStatelessSessionProxyFactoryBean is included in both spring.jar and spring-context.jar.

[ElPapa]

Oh that *IS* interesting. I have both of them in my classpath.... Sounds like the classloader is choking as a result... :-/

[irbouho]

ElPapa,

If you use spring.jar in your classpath, there is no need to include the other jar from spring distribution as spring.jar contains all the Spring Framework classes.

[ElPapa]

After rooting around in the JAR files I see that now. However I'm still having the same problem.


14:06:35,375 ERROR [ContextLoader] Context initialization failed

From my applicationContext.xml file...

<property name="businessInterface">

</property>
</bean>

[ElPapa]

OK... I decided to take a step back from my project, create a new project, put an EJB in that, and then try again to see what happened.

I'm STILL getting java.lang.ClassNotFoundException. And the spring.jar file is deployed along with my EJB.

Here's the springconfig.xml file that I'm loading in a simple Java application, the applicationContext file from that sample, and the stacktrace.

If this matters at all, I'm using Framework 1.01. I could REALLY use some help here. This is making me a bit batty.

Exception in thread "main"

[Colin Sampaleanu]

Looks like you're basing this off the integration test ejbtest sample. Does _that_ work for you?

I don't think the ClassNotFoundException is actually referring to
SimpleRemoteStatelessSessionProxyFactoryBean
if you read the log carefully. The error occurs during the creation of it, but as far as I can tell the error is in the remote invocation.

Regards,

[ElPapa]

Colin,

My code is based roughly on the sample code in CVS (seemed like a good place to start).

I'll dig around in the sample code a bit more and see what I can find.

I'll keep you posted.

[ElPapa]

Colin,

So far I the best I've been able to do is narrow down *where* the ClassNotFoundException is happening...

From DefaultXmlBeanDefinitionParser.java starting at line 259

if (this.beanClassLoader != null) {
Class clazz = Class.forName(className, true, this.beanClassLoader);
rbd = new RootBeanDefinition(clazz, cargs, pvs);
} else {
rbd = new RootBeanDefinition(className, cargs, pvs);
}

The exception occurs when "className" is "org.springframework.ejb.access.SimpleRemoteStatele ssSessionProxyFactoryBean"

Help...?? :(

[ElPapa]

I give up... :oops:

I've put the code on one of my servers in a ZIP file. The project is done in JBuilder, but should be easily sucked into eclipse. I've stared at this until my eyes are blurring. And I think I need one of the 'higher-powers' here to loan me a set of eyes.

http://mywebpages.comcast.net/daorriss/extras/springEJB.zip

So far understanding this part of Spring is really frustrating me. Other parts I've used fine, but this... eeeesh. :(

Anyway, I'd appreciate any help you can give. The springEJB.html file in the project as some notes on how to run the test client that's included with it.

Hi, ElPapa:
I downloaded your code, and tested, finally I made it works, let me explain:
1. I deployed your code to weblogic 8.1,
in MANIFEST.MF add depended reference:
Class-Path: srping.jar log4j-1.2.8.jar commons-logging.jar commons-collections-2.1.1.jar, and put jars inside EJBModule.jar, and
weblogic-jar.xml:<weblogic-ejb-jar>

<weblogic-enterprise-bean>

<ejb-name>SimpleEJB</ejb-name>
<jndi-name>SimpleEJB</jndi-name>

</weblogic-enterprise-bean>

</weblogic-ejb-jar>

same as jboss.xml, and then no luck, can not find spring.jar ...., can not deploy,
2. I put spring.jar,log4j-1.2.8.jar,common-logging.jar in server classpathg, it deployed,
3. I test you TestRemoteProxy, get Exception......

4. finnally I figure out, add aopalliance.jar in server classpath. it works.


Would you mind fixing my problem: why following structure, weblogic can not find the depended jars?

EJBModule.jar
|_pring.jar
|_log4j-1.2.8.jar
|_commons-logging.jar
|_aopalliance.jar
|_com
_codethought
_springejb
_SimpleEJB.class
_Simple*
|- META-INF
|_ ejb-jar.xml
|_ vendor-ejb-jar.xml
|_ Manifest.mf

ping Lu

[ElPapa]

pinglu,

THANKS!! That was perfect.

About your problem. I remember some odd 'quirks' about WebLogic's classloader. I'll have to do some reading and see what I can find. Have you tried putting everything in an EAR file? Have the EJB Jar contain NONE of the dependencies for the JAR file and instead include them in the EAR file along with the EJB JAR file.

That's what I do...

As you suggested I have EJB.jar without depend jar and put in a ear file, all the third party jars in APP-INF/lib
Simple.ear
-EJBMOdular.jar
-META-INF\application.xml
-APP-INF
-lib
spring.jar
common-logging.jar
aopanliance.jar
Thanks!

[ElPapa]

Yea I've found that EAR files make life a lot easier... :)
