Is your database working?  Is it listening?  Have you configured it
at all?  What error message do you get?

Yes my DB es working, in fact, I can access to it with
Perl,

Yes I configured all, with ./configure --with-java
with-perl and I installed it, other stuffs that I
installed was tomcat 4.0.3, java 1.3.0(because 1.4.0
did not work very well) and ant 1.3

 What error message do you get?

this is the error messages
Exception
javax.servlet.ServletException: Can't create
DataSource: org.postgresql.Driver

Root
javax.servlet.ServletException: Can't create
DataSource: org.postgresql.Driver

    It's probably a class loading exception; whatever is trying to
instantiate the connection can't find the class "org.postgresql.Driver".
Are you sure you have the JDBC driver in your WEB-INF/lib or in the
correct area of the server's class hierarchy?
    There's a small chance it could be a ClassCastException, if the
version of the driver you're using is not suited for the version of the
JDK you're using, but I think the former is more likely.
