You may therefore also need to copy the JTA 1.1 API into the application server's server/XXX/lib dir | - lib/ext/jta-1_1-classes.zip | You also need the jbossjta-properties.xml file on the classpath, which probably means WEB-INF/classes/ ... Not that bundling JBossTS in a webapp is a good idea anyhow if you a) have more than one such webapp or b) actually expect crash recovery to work.
