Hi, pals,
I'm working on the embeded tomcat server 5.5.12 which is started from eclipse.
And i could start/stop the tomcat successfully. but if once i stop the tomcat server, and then start it, a exception was thrown. It seemed that something wrong with WebAppClassLoad. Could anyone give me some advice about it?
I searched google, but find little useful information. :(
thx a lot for ur kindly help. The attachement is the source codes and log file.
Blue night is someone's magic.
