如何使用Eclipse附加JSP调试源

Question

I am able to set breakpoints and debug JSP files in eclipse (see this post Debug JSP from eclipse )

The problem is I don't know how to attach the JSP source files so that I can see where debugger is stepping.

I have tried the following things with no success:

• add the maven project as source to the debug configuration
• Add the dynamic project nature to the project
• zip all jsps in a jar (like regular java sources)

I don't know what eclipse is really expecting as artifact containing the JSP source files.

PS: I use Weblogic 10 and maven.

Answer 1

Put a debug point on jsp page, start server in debug mode. When the debug point is hit, you can examine the variables. You need to manually open the jsp page to see what is the exact code. But that is good enough for me.

Answer 2

And you shouldn't. You must not have java code within JSP files. They are only for rendering the view, so no processing there. Do that in a servlet. See this extensive answer for why and how to do that.

Technically, you can attach the sources generated by your servlet container (in tomcat they are generated in the work directory), but you'd better fix things and move the logic to servlets and debug it there.
