I'm trying to run an ANT task that will start an instance of the websphere server. I want to run the task from within WSAD 5.1.2 (run ANT). The wsStartServer ANT task fails. The server log shows an incorrect java version (1.3.1) and incorrect Java Home (eclipse/jre) . When I use the startServer.bat, the correct Java version (1.4.1) and Java Home ( runtimes\base_v51\java\jre ).
