When you deploy two Web applications as Web archives (WARs) into JBoss' deploy folder, you expect them to run independently of each other. But this does not happen.
WebApp1.war
+ WEB-INF
+ lib
+ abc_v1.0.jar
+ classes
+ com.abc.Class_v1.0
WebApp2.war
+ WEB-INF
+ lib
+ abc_v1.1.jar
+ classes
+ com.abc.Class_v1.1
If you deploy the two Web applications in the above structure, one of them will break. This is because JBoss/Tomcat5 classloading mechanism's class loader is used by
all applications—even when they are in different WAR files.
The solution is to change the \deploy\jbossweb-tomcat50.sar\META-INF\jboss-service.xml file. If you change the UseJBossWebLoader attribute to false, a different classloader will be used for different WAR files.
