JBoss AS 7 reference to class in other module in this same ear

Question

Hello i try to migrate from jboss 4.2.3 to jboss 7 and i have some issue. My question is How can i point a class in other jar(ChartGenerateVariables.class in dts.jar), when it's needed in war(dts.war). How edit war that he know about needed class in other module(this time in jar file) and other question is how resolve this error could not load entity class 'com.recglobal.dts.model.views.PlanSalesValue' with PersistenceUnitInfo.getNewTempClassLoader(). About this issue i don' have any clue couse this time it's not a jar file or something but its own class, only that it is a @Entity. MAybe some will now something about that.

Answer 1

JBoss 7 has a new module system, so modules are not visible by default anymore, which is great, because now you can explicitly control the dependencies. All you have to to is adding the dependencies to your Manifest file.

https://access.redhat.com/site/documentation/en-US/JBoss_Enterprise_Application_Platform/6/html/Development_Guide/Add_an_Explicit_Module_Dependency_to_a_Deployment1.html

Answer 2

You have got simple error : Caused by: java.lang.ClassNotFoundException: com.recglobal.dts.chart.ChartGenerateVariables from [Module "deployment.dts.ear.dts.war:main" from Service Module Loader]

That mean you havent got this class in your classpath.

In ear package you have got war , ejb and alco client jar. But in JEE6 there is good practice hold all jar into lib directory. So all jar in lib dir have got global visible for other package war , ejb .. .

For example we are delete arr jar dependencies from war package, because we have got multiple war`s so our project might be very heavy. We copy all jar dependencies into lib ear folder.

In maven you just simple add :

 <artifactId>maven-war-plugin</artifactId>
        <configuration>
          <packagingExcludes>WEB-INF/lib/*.jar</packagingExcludes>

and in your ear pom set skinnywar
