Because JBoss has its own mechanism for referencing JNDI data sources, the resource-references in the web.xml file located in the pentaho.war are not needed. You must remove these resource-references for the Pentaho Server to operate properly.
Navigate to the pentaho/server/pentao-server/*your jboss installation directory*/standalone/deployments directory.
Use a ZIP extraction utility (such as 7-Zip, WinZip, or Archive) to view the contents of the pentaho.war file.
Do not unzip or extract the contents of the file.
Navigate to the WEB-INF directory and open the web.xml file in a text editor.
Delete all <resource-ref> tagged entries including everything between the <resource-ref> and </resource ref> tags.
Save and close the file.
The ZIP extraction utility that you used might show a prompt that asks whether you would like to update the file in the pentaho.war archive. If this prompt appears, confirm that you would like to update the file.
