Calling another servlet from a servlet

Question

I'm working on a servlet and would like to know how to
call another servlet, by clicking on a form button
or a hyperlink that was generated from the first servlet,
is it only possible if the second servlet is called
in an shtml page? Can you please give me an example
of how to do this not using shtml pages?
(I'm working with JDeveloper 2.0)
When will the book be out for JDeveloper 2.0?
We're also having problems deploying the servlet
to the Java Web Server (1.1.3)
It seems to have a problem connecting to the database.
We get the first page of the servlet but the
second page is generated from the doPost()
and connects to the database using oracle JDBC thin
gives a http 500 internal server error ,
and we followed the instructions from JDeveloper
can the problem be caused from the connection string that
I used in the servlet:
Class.forName("oracle.jdbc.driver.OracleDriver");
DriverManager.registerDriver(
new oracle.jdbc.driver.OracleDriver());
con = DriverManager.getConnection(
"jdbc:oracle:thin:@(description=(address=
(host=10.10.10.53)(protocol=tcp)(port=1521))
(connect_data=(sid=OR8A)))",
"im_dev","im_dev");
or the configuration of the web server?
(web server: Solaris 2.7 running on Intel)

Hi
The sample acme video demo in JDeveloper does something similar.
It has main Servlet "WebAppServlet.java" which overides the
doPost and doGet methods and this methods calls someother java
classes do perform some specific business logic which return a
html page in a String format to "WebAppServlet.java".
Open the samples directory in JDEveloper 2.0 with WebApp_81.jws
to look at the source code.
Steps to run the sample are included in the help system.
regards
