Debugging Guided Procedures

Question

I created/deployed the webdynpro development component and created a callable object in GP.  When I test the callable object it executes but when I hit complete it does not complete to the View Test Results which seems to mean that my complete method is not being called or is failing.  I had a couple of questions on debugging. 
1.  The System.out and System.err go to the C:\usr\sap\J2E\JC01\work\std_server0 log, right???  That is where e.printStackTrace() should also go, correct??
2. When I modify my component in Studio, Rebuild, Archive, and Deploy, does the callable object automatically pick up the modified component or is that cached somewhere??  I tried to put some debugging statements in my component but I can't find them anywhere.
Thanks for the help.

Default location for server log is C:usrsapJ2EJC01j2eeclusterserver0logsystem
Default location for default trace is C:usrsapJ2EJC01j2eeclusterserver0log
For your WD callable object (CO) questions, the CO you created is valid even if if keep modifying the WD as long as you don't change the GP interface (GP input/ouptut/result state/execption). if you change the GP interface definition (method GetDescription), then you'll need to delete and recreate you CO.
Yo ucan find your debugging statements at the right location. You can also debug your WD by setting at breakpoint, run a debug, and test your wd in GP runtime. Make sure your server setting for debugging in configtool.bat is on. Here is an example of debugging con cept in case you need a reference https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/5859c7c6-0701-0010-3081-ecc15e3d2186
