Re: Debugging Java class generated from JSP

Hi Nathan,

JSwat breaks on the location okay, but the window with the source is not 
synchronized with the break, and the source window synchronized with the 
break is the "source could not be found" window.

Here is the complete set of source paths:

C:\JDOCourse\labs\tools
C:\apps\java\jakarta-tomcat-5.0.19\work\Catalina\localhost\rental
C:\apps\java\jakarta-tomcat-5.0.19\src\jakarta-servletapi-5\jsr154\src\share
C:\apps\java\jakarta-tomcat-5.0.19\src\jakarta-tomcat-catalina\catalina\src\share
C:\java\Tapestry-3.0\framework\src
C:\java\Tapestry-3.0\contrib\src
C:\java\JDK142\src.zip
C:\java\JPox1B3\src\src\java
C:\java\JDO1.0.1\src

The Tapestry source paths are leftovers from another use of JSwat.

Here is a directory listing showing the files at the location:

  Directory of 
C:\apps\java\jakarta-tomcat-5.0.19\work\Catalina\localhost\rental\org\apache\jsp

09/16/2004  09:22 AM             5,338 SessionLock_jsp.java
                8 File(s)         88,587 bytes
                2 Dir(s)  15,336,022,016 bytes free

Does this help?
