Thank you very much for the help Doug, but it still
give an error message that was start with:
Apache Tomcat/4.1.29-Error report
HTTP Status 500-Exception report
message description
The Server encountered an internal error that
prevented it from fulfilling this request
exception javax.servlet.ServletException:
null at LoginServlet.doPost(LoginServlet.java:59)
and continued with what I enclosed in my previous
message

do you mean the connection between the J2ME emulator
and tomcat or between tomcat and the database
management system?
When I checked the web descryptor of the example
application in tomcat, I found it also contained
filter directive while mine doesn't,could it possibly
be a problem?
The more I read this lists, the more I convinced, that
this lists is filled with person with a strong will to
help others to grow their knowledge. Thank you for
advance everybody :)

I don't know how to set it in MIDlet (actually the
listing that I attach is what I've seen in Paul
Tremblett's book),I thought it will be set
automatically like what happened in html form

well, that's my problem,I'm still new also in J2ME
especially in it's Http method, do you mind to show
me a kind of example how to correctly generating an
HTTP POST in MIDlet ?

I've set the content-length properties but the
message error still the same. What item is actually
have to be set for the header?, in the catalina_log
it prompts like this (I copy-paste from catalina_log
in Tomcat's logs folder):

is it something to do with my URL path in MIDlet or
the way to define context description for the
application that isn't correct ?
thank you very much

I just looked at the code you posted. I think it's a
NullPointerException within line 33 of your LoginServlet
int kode = Integer.parseInt(request.getParameter("kode"));
This will throw an NPE if the "kode" parameter is not set...
Is your MIDLet TextField empty when you get this error?
If not, check that your MIDLet code is properly generating an HTTP POST
request (you're not setting the content-length header, there needs to be
a blank line between http headers and the body etc). Turn on the
RequestDumperValve in your tomcat's server.xml to check what tomcat
receives...
HTH,
Jon
