问题
im trying to migrate my JBOSS 5.1 application to JBOSS 7.0.2. In admin console i select deployments -> add content and my .war and try to enable it. I already resolved some problems, but cant figure out this one: (in short, in long at the end)
Caused by: java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener from [Module "deployment.ZaprogsProject.war:main" from Servic
e Module Loader]
I copied to JBOSS7\standalone\lib\ the following files:
spring-aop-3.0.5.RELEASE.jar
spring-asm-3.0.5.RELEASE.jar
spring-beans-3.0.5.RELEASE.jar
spring-context-3.0.5.RELEASE.jar
spring-context-support-3.0.5.RELEASE.jar
spring-core-3.0.5.RELEASE.jar
spring-expression-3.0.5.RELEASE.jar
spring-jdbc-3.0.5.RELEASE.jar
spring-orm-3.0.5.RELEASE.jar
spring-test-3.0.5.RELEASE.jar
spring-tx-3.0.5.RELEASE.jar
spring-web-3.0.5.RELEASE.jar
spring-webmvc-3.0.5.RELEASE.jar
I have read this: https://docs.jboss.org/author/display/AS7/How+do+I+migrate+my+application+from+AS5+or+AS6+to+AS7 (Debug and resolve ClassNotFoundExceptions and NoClassDefFoundErrors) but cant find a solution for me and still getting the same error. Can anyone help?

回答1:
I would not put those JARs in that directory. Try them in your WAR file's WEB-INF/lib. The class loader will find them there.
You need to understand that all Java EE app servers use a hierarchy of class loaders: bootstrap, server, application. JBoss wasn't finding that class when it needed to.
回答2:
JBoss AS 7 does class-loading in a diff way.
All classes in the WAR are loaded with the same class loader. This means classes packaged in the WEB-INF/lib are treated the same as classes in WEB-INF/classes. Hence it works for you.
But as you have said correctly your WEB-INF/lib is bloated.This would not be the correct way.
You would need to make a module : Goto modules folder, make folder structure with main folder and put your jar and modules.xml with entries in it. Something like :
<main-class name="org.jboss.msc.Version"/>
<resources>
<resource-root path="jboss-msc-1.0.1.GA.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="org.jboss.logging"/>
<module name="org.jboss.modules"/>
<!-- Optional deps -->
<module name="javax.inject.api" optional="true"/>
<module name="org.jboss.threads" optional="true"/>
<module name="org.jboss.vfs" optional="true"/>
</dependencies>
You would also need to update MANIFEST as well. Details are here : https://docs.jboss.org/author/display/MODULES/Module+descriptors

There is a major change Jboss 7 when compared to previous versions.If you want to access any libraries outside your war file, it should be installed as module. Check https://docs.jboss.org/author/display/MODULES/Introduction In this case you should install Spring as module and specify the name of the module as dependency in your application's manifest file(check Manifest module information)
