[em...@unisys.com.br]

 

 

I just installed the tomcat 5.5 with two instances running in the same ip
address, but in different ports. Its works but the manager just work in one
of them. The manager for the second port show me the following error:

 


HTTP Status 500 -

(Odd that unisys.com.br is not a resolvable DNS name, even from inside the corporate network...)

Looks like the server/webapps directory is missing, corrupt, or inaccessible in your second copy of Tomcat.  Do a directory comparison of the two installations to see if anything's different.

Also, if you're running on Windows (you didn't bother to tell us the platform or JDK/JRE level), and the same jar locations are being used by both Tomcat instances, you may need to set the antiJARLocking attribute for any webapps that are sharing jar locations; look here for details:
