Deployment Descriptors in Websphere

[Prakash Dwivedi]

Hello Friends,
following is how my session bean is represented in ejb-jar.xml. In this file extra attribute called "id" is added to various tags. Is this permissible according to ejb specs?
Also will be ejb application be portable (to different app server), with these kinds of deployment descriptors.

  
<session id="ClientBean">
<ejb-name>ClientBean</ejb-name>
<local-home>com.test.ClientBeanLocalHome</local-home>
<local>com.test.ClientBeanLocal</local>
<ejb-class>com.test.ClientBeanBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
<ejb-local-ref id="EJBLocalRef_1085565372125">
<description></description>
<ejb-ref-name>ejb/EMPLOYEE_DATA</ejb-ref-name>
<ejb-ref-type>Entity</ejb-ref-type>
<local-home>com.test.EMPLOYEE_DATALocalHome</local-home>
<local>com.test.EMPLOYEE_DATALocal</local>
<ejb-link>EMPLOYEE_DATA</ejb-link>
</ejb-local-ref>
</session>

Yes it's permissible -- in fact adding an ID attribute to any tag is permissible in any XML document -- it's in the XML specification. And yes, the files are completely portable.

thanks for the explaination,
i am having one more doubt, that if i want to shift my existing ejb-application (ear file) which is running on some different app-server (say oracle 9ias) to websphere. In oracle 9ias deployment descriptors doesn't have id attribute. Also this application will not contain other websphere deployment descriptor files (like ibm-ejb-jar-bnd.xmi and ibm-ejb-jar-ext.xmi). So will i be able to deploy this ear file in websphere?
If not, is there any tool by which i can generate websphere specific deployment descriptors.

thanks

Simply import your existing EAR file into the WebSphere Assembly toolkit (ASTK) and then save the EAR file. The ASTK will add in the additional XML files.

Thanks again,

I am very interested to learn more about deployment descriptors in websphere server. I read your article EJB Metadata in WebSphere 4.0 - A Tale of Four Files, and found it very useful, but i am having one doubt, will it be fine if i read from this article and work on Websphere 5, or is there some other article for websphere 5.

Thanks

We have not updated the article for WAS 5.0 yet, no, but the first article still applies (mostly) in WAS 5.0. The second one (on associations) is out of date since (as the article states) associations are part of EJB 2.0 and included in the standard EJB dd.
