Websphere MDB activation with alternative deployment descriptor "<alt-dd>"

StackOverflow https://stackoverflow.com/questions/22378977

Question

I'm trying to deploy an MDB with an alternative deployment descriptor located in my EAR in my Websphere 8.5 (Java EE specification). Example:

<module>
  <ejb>arq_frameworkEJB.jar</ejb>
  <alt-dd>dds/ejb-jar.xml</alt-dd>
</module>

The problem is the WAS EJB container is complaining about not finding the required binding file ibm-ejb-jar-bnd.xml (this binding is required to activate the MDB). The error says:

com.ibm.ejs.container.EJBConfigurationException: REQUIRED_BINDING_NOT_FOUND for MDB: arqMDB

I've tried multiple locations for this file (inside the arq_frameworkEJB.jar), inside the EARs META-INF folder, but it doesn't work. I've searched on internet, but haven't found any documentation neither mention about where this file is supposed to be.

Was it helpful?

Solution

Solution:

  1. Activate "trace" mode in WAS.
  2. Open "trace.log" and check where is WAS looking for alternative binding file.

trace.log:

[20/03/14 9:19:08:557 CET] 00000046 bindext 3 com.ibm.etools.commonarchive.impl.EARFileImpl initializeModuleExtensions Alternate Bindings URI: [ALT-INF/arq_frameworkEJB.jar/ibm-ejb-jar-bnd.xml]

Try this configuration:

ALT-INF/ejb-jar.xml
ALT-INF/arq_frameworkEJB.jar/ibm-ejb-jar-bnd.xml

Thats works!

OTHER TIPS

The ejb binding file should be placed in ejb-module/META-INF in ejb project. For web project it should be in WEB-INF/. It takes the same location as ejb-jar.xml.
