Eclipse M4 and MyEclipse 3.6.4

Previously I was running Java 1.4.1_05 and Tomcat 4.1.27. I have used the Tomcat launcher in MyEclipse a lot to debug web apps.

Today I upgraded some versions. I moved to Java 1.4.2_03 and Tomcat 4.1.29. Tomcat 4.1.29 launched independantly works fine. In Eclipse, I changed my JDK to point to the new Java SDK. I changed the paths for Tomcat 4 in the preferences to point to 4.1.29 instead of 4.1.27 (basically I just changed the 27 to a 29 in the 3 paths). I changed the JDK that Tomcat 4 uses to the new JDK. Now when I try and launch Tomcat from within Eclipse I get an error:

It can’t find a j2ee.jar? So I manually add the real j2ee.jar (from my J2EE 1.3 SDK) and then get this:

Now it can’t find the catalina.jar? If I manually add every jar to the classpath that tomcat needs to launch, it will go, but I shouldn’t have to do this – I didn’t before.

Tomcat 4.1.29 changed the Tomcat launch model which caused a problem with the MyEclipse connector. It is fixed in 2.7 RC1, but 3.7 RC2 will not be available until the 5th. In the short term the workaround is to continue to use 4.1.27 until 3.7RC2 ships. Sorry for the inconvenience.
