I've installed Java2 1.3 development environments on Solaris several times without this problem, but I'm new to Win2k. Do I need
J2EE?
When I compile my connection pool I'm told javac can't find "Timer" which I think is part of java.sql. When I run
JSP under
Tomcat I'm that I have an illegal constant pool type, probably because it can't compile the class.
I have jar tvf 'd all the jars I can find. I don't see java.sql. It isn't part of lang is it?
The examples in Tomcat run just fine. So does MySQL from the command prompt.
I have compared my CLASSPATH to my Solaris machines (which run this code just fine). Here it is:
C:\java\lib;C:\java\lib\tools.jar;C:\java\lib\dt.jar;C:\java\jre\lib\rt.jar;C:\progra~1\apache~1\jakarta-tomcat\lib\servlet.jar;C:\Progra~1\Apache~1\Apache\beans;C:\Progra~1\Apache ~1\Apache\classes;C:\Progra~1\Apache~1\Apache\classes\mm.mysql-2.0.4-bin.jar;.
Here is the error report from tomcat:Internal
