hi there,

I am trying to get the Tomcat 4 integration to work, but it fails. When I go to Run/stop Servers ->Tomcat 4 -> Start, MyEclipse starts, but throws this error:

java.lang.NoClassDefFoundError: javax/management/MBeanRegistration

see below for complete error

this class is located in mx4j-jmx.jar, but adding this to the classpath (either prepend or append) doesn’t work…
Starting tomcat from the command line by calling the startup.bat file works fine

somewhere on the net I found that using the Tomcat 5 instead of Tomcat 4 application server integration would fix it, but no success. Also, setting up integration with Orion 2.02 works fine

Anybody any ideas?

OS: windows XP
eclipse: 2.1.2
MyEclipse workbench: 2.6.4
Tomcat : 4.1.29
JDK: 1.4.1_05

Dirk,

This problem is a result of changes made in the startup configuration in the 4.1.29 build of Tomcat. The problem was first discovered in this thread:
https://www.genuitec.com/forums/topic/can-not-start-tomcat-4-1-29-enhancement/#post-199835

This will be addressed in our next service release. The current workaround is to use a slightly earlier version of Tomcat (4.1.27).

ha,

I searched the wrong forum:)

Thanks Scott for the quick answer, I’ll downgrade in anticipation of your service release
