在调试模式下启动服务器在eclipse上不起作用

Question

I'm trying to start a jsf application in debug mode but it doesn't work. I've made some modifications on the code, and then it stoped working. i've sent these changes to my friend and it works normally.

Here's the log:

But if i try to start the server normally, it works. I've tried to clean both the project and the apache server, but it didn't help.

Answer 1

Delete the jar that deploys to solis_web\\WEB-INF\\lib\\servlet-api-2.5.jar . It conflicts with the version of those classes built into (and provided by) Tomcat. Open the project's Properties dialog and make sure the Server page has it pointing to Tomcat; that should correctly put the APIs in the build path without duplicating them.
