Hello,

Is there a place in an EJB jar's directory structure for other jars for use by the EJB? Something like the WEB-INF/lib in web applications?

Thank you,
Yuriy

Not really. Although different vendors offer different packing solutions and they have different classloading architectures for their containers, it is most common that the common library to be packed within the same ear (where the ejb goes) and edit the manifest file of each ejb-jar file. For example if you intend to make iText.jar and commons-collections.jar available to your ejbs, then you should add the next line to the MANIFEST.MF file of each ejb-jar that needs to use those libraries:

This example assumes that both iText.jar and commons-collections.jar libraries get packed into the ear�s root (otherwise you need to specify the proper path as well).
