RE: How to get data source in JRun4
Just do the lookup on the dsName. Remove the java:comp/env/jdbc. See the migration documentation in JRun 4 docs.

RE: How to get data source in JRun4
JRun 4.0 uses a simpler JNDI structure than 3.1 did. Take a look in the data-source section of jrun-resources.xml for your server. There should be a field called jndi-name. That value is all you need to use to look up the datasource, without any prefixes. Hope this helps.
