多个应用程序共享TomEE中的通用EJB JAR

Question

I have an EJB jar DetailsLookup.jar which needs to be shared by two consumer applications - VehicleMake.war and VehicleModel.war

I have placed the EJB jar file under <catalina_base>/lib and both the war file under <catalina_base>/webapps

When I deploy only one of the WAR files, the deployment is successful, but with 2 WAR files I get the error as below. It seems, TomEE is trying to deploy the EJB for every consumer application instead of deploying it only once

Caused by: org.apache.openejb.DuplicateDeploymentIdException: Application cannot be deployed as it contains deployment-ids which are in use: app: D:\apache-tomcat\instance1\webapps\VehicleModel
    DetailsLookup
    at org.apache.openejb.assembler.classic.Assembler.createApplication(Assembler.java:790)
    at org.apache.openejb.assembler.classic.Assembler.createApplication(Assembler.java:756)
    at org.apache.tomee.catalina.TomcatWebAppBuilder.startInternal(TomcatWebAppBuilder.java:1308)
    ... 32 more

I have also noticed that when I deploy only VehicleMake.war , the JNDI name for my EJB has the application context path also appended (which says that the EJB is deployed per project and not common)

Expected JNDI name:

global/DetailsLookup!com.my.company.details.service.DetailsLookup

Actual JNDI name:

global/ VehicleMake /DetailsLookup!com.my.company.details.service.DetailsLookup

Can anyone help me to identify what the issue is with deploying EJB and if I need to change any configurations to deploy it as a common EJB instead of application specific?

In conf/system.properties , you can change the name of deployed artifacts to avoid collisions.

Try adding this line:

openejb.deploymentId.format = {appId}/{ejbJarId}/{ejbName}
