Hi gang,
I am trying to convert the ASP file to a JSP file. I am getting an empty
parameter name somewhere deep inside my Java classes and it is throwing an
exception. Can you please take a look at both files and tell me whether both of
them are doing the same thing (or) am i missing some functionality in the JSP
page which is giving me this exception. Thank you.
I don't get this error in asp..
One more thing..initially when i access the JSP page i am getting the below
error in weblogic...
"From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.5.1 500 Internal Server Error"
But on the same page when i do a refresh, i get my data perfectly.
btw i am using jsp 1.0 running on WebLogic and/or Jrun 2.3.3. I keep getting the
same error on both the webservers.
