Hi,
I downloaded the j2eetutorial zip file from the sun java site and
was trying out the 'converter' example from it. The instructions are
given in the online J2EE tutorial book also available at the sun
java site. I followed all the instructions and everything seems to
be fine till the time i submit a conversion request throught the
browser using localhost and port 8000. On doing so, i get the following
error:
Error: 500
