Tomcat can't start as service

[sofun]

Dear Sir,   Sorry to bother u, But I have some problem about Tomcat can't start as NT service. I am a newbie to java and JSP. I follow the instruction to install JDK 1.3 , apache and tomcat. But When I try to run Tomcat as service.  I have error message "about could not start the tomcat service on Local computer. The Service did not return an error. This could be an internal windows error or an internal service error. If the problem persists, contact your system administrator"   and I checked my logs file the jvm.stderr have message java.lang.NoClassDefFoundError: "Group\tomcat\classes;G:\Apache Exception in thread "main" java.lang.NoClassDefFoundError: Group\tomcat\classes;G:\Apache Exception in thread "main" java.lang.NoClassDefFoundError: Group\tomcat\classes;G:\Apache Exception in thread "main" java.lang.NoClassDefFoundError: Group\tomcat\classes;G:\Apache"   apache path is G:\apache group\apache tomcat path is G:\apache group\tomcat JDK path is G:\JDK1.3   I have set the wrapper.properties in the tomcat/conf folder   wrapper.tomcat_home=G:\Apache group\tomcat wrapper.java_home=G:\JDK1.3   but I still can't fix the problem.. is that I have missed something of done something wrong?   regards   sofun Lo
