Dear all,
I'm quite new using HttpServlets, that's why I hope you can help me!
I'm using an HttpServlet on Tomcat 5 that is prepared to receive POST HTTP
requests from remote machines.
If I use an html form and I submit a text to this servlet (method post), the
get parameter of the http servlet returns the text content ok (with or without
the % character in the text).
When this form, instead of submitting directly to the http servlet, submits to
another program in background (ex: a php program), which then does the post to
the servlet, the result is:
The get parameter returns null if the text has the % character (and so we
cannot see anything from the text).
It is not a problem of the background program, because if the program posts a
simple php file, just to show the text contest, we can see the text ok, even
with the % character. This only happens if the program posts to the this
HTTPservlet. Furthermore, this problem happens also to other users who wish to
POST requests to this HTTP Servlet. Those users have their own programs and in
then they POST the text to our HTTP Servlet.
Am I missing any important detail about char encoding?
I'll send you an example of my HTTPServlet code to help you on the
troubleshooting.
Hope you can help me!!!
Tiago
