Right. This is a great description of what you're doing: without it, it would have been impossible to figure out what you were doing. This is fixed now, but the workaround (which allows working gracefully with the new deployer, so it's good) is to use an XML file named ROOT.xml, with: <Context docBase="/iq" reloadable="true" /> > My solution which proves this was to simply delete ROOT folder from > c:\jakarta-tomcat\webapps and restart TC.

For JNDI, you need to make sure you're not using ResourceParams. The new syntax is in the docs. -- xxxxxxxxxxxxxxxxxxxxxxxxx Rémy Maucherat Developer & Consultant JBoss Group (Europe) SàRL xxxxxxxxxxxxxxxxxxxxxxxxx --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
