Hello All,
  I am trying to  convert a pure JSP program into a portlet.  To be more specific, I am converting JSP file browser from
http://www.vonloesch.de/jspbrowser.html  into a Gridsphere portlet.  In the process, I encounter the following problems

1)Convert all JSP requests to  portlet requests. 
      The <a> tags, submit actions in the JSP  point to URLs outside portlets. So had to change them to point to portlal.

2)Request parameters and attributes
       Request parameters and attributes were no longer available inside the JSP. Am not sure why this happens.  How do people overcome
this problem.

3)POST variables are not accessible inside JSP.

As of now these three seem to be the major problem.  If anyone has any solutions or comments on the same, please let me know.
