my ear structure

myear

| lib/log4j and stuff

| ------ MYAPP-WebApps-Common.jar (com.web.app.webapps.common.virtualoperators)

| ------ MYAPP-AAA-Common.jar (com.web.app.aaa.common.virtualoperators)

| ------ MYAPP-WebApps-Billing.war

both war have MANIFEST.MF with Class-Path which icludes both jars

i tried to solve this through jar/META-INF/MANIFEST.MF by adding: Dependencies: deployment.myear.ear.MYAPP-WebApps-Common.jar and also tried (just tried) with jboss-deployment-structure.xml but nothing helps..

Its important to say that this ear works without any problem on IBM Websphere

can you please halp me to solve this cross talking issue between jars and wars

thank you

Tomislav

Hi there,

Welcome to the JBoss Community!

Can you please respond with the output of:

{code}jar tf myear.ear{code}
as your ASCII art is not very clear.

Additionally, can you attach your application.xml file?

Generally, you want all jars in the EAR/lib directory and the WAR in the root of the EAR.

A common error is to list library jars in the application.xml file too.

Hi,

i cannot post output of ear because of security reasons (productive application for user login).
i solved a problem by moving every jar in EAR/lib directory but i would like to preserver ear same as i twas before.
is there any way to list all lib directories that will ear count as lib?
in ear we have:
Ear/log4 dir, ear/oracle dir, ear/b2b dir and all of them ar lib directories

also, when i fixed this problem as you mentioned, now i have different one.

in my ear i have number of wars.
problem is that war lat say MYAPP-WebApps-Auth.war uses classes from MYAPP-WebApps-Billing.war, MYAPP-WebApps-Error.war, MYAPP-WebApps-System.war, MYAPP-WebApps-Subs.war

and i reveive:
23:35:28,007 ERROR [] (MSC service thread 1-6) Exception during initialization of module checkSessionExistsPlugin(class=xxxxxx.logindomainredirector.plugins.CheckSessionExistsPlugin):
java.lang.RuntimeException: Error during creation of Module checkSessionExistsPlugin(class=xxxxxxxxxx.logindomainredirector.plugins.CheckSessionExistsPlugin

Caused by: java.lang.ClassNotFoundException: xxxxxxxxxxx.plugins.CheckSessionExistsPlugin from [Module "de
ployment.myear.ear:main" from Service Module Loader]

im sorry that i cannot post full stack because of company regulations.

bottom line is that i need to tell wars to communicate between themself, to make classes visible between them

thanks
Tomislav
