Deploying Servlets In JavaWeb Server

Question

Hi,
I am using Jdeveloper 2.0 Beta for developing servlets.I tried
the HttpServlet tutorial example.
I have compiled the servlets and moved the necessary class files
to the /servlets dir of the web server including the dependency
file.
(Do i need to set jboenv.bat for this too??I think it is only
for database servlets)
In the setup of webserver, i added the servlet MyServlet and
class name as MyPackage.MyServlet and followed the tutorial
steps.But I am not able to see the servlet o/p when I invoke
using http://<server_name>:9090/servlet/MyServlet
cannot load local code 'Mypackage.MyServlet' in the alert dialog.
I am not sure where i am going wrong
When I say load in the config tab of the Servlet admin tool I
get the foll error
cannot update servlet MyServlet:
cannot load local code "MyPackage.MyServlet"
Thanks in advance

To have DBServlets run from the JDeveloper directory, you can run
the JavaWebServer with this little script. It calls the setjboenv
script, avoiding "directory with spaces" problems.
subst z: "C:\Program Files\Oracle\JDeveloper 2.0"
z:
cd z:\bin\
call setjboenv.bat z:
httpd -nojre
After running this script, the JDeveloper directory "myclasses"
will be in the Web Server's classpath. Storing your
MyPackage/MySTServlet under myclasses should then be ok.
If you want to move things to the Web Server directory, you may
need to copy some JAR files and directories. This will be
documented in the production version.
For DbServlets, you will need to copy the cascading style sheets
and images. Here are the steps:
Navigate to your JDeveloper directory
Go into the redist directory
Copy the dbservlet directory
Past into the public_html directory of your JavaWebServer dir
For DBServlets you will also need to copy the following archives
to JavaWebServer's lib directory and add them to its classpath:
JBO HTML [ jbohtml.zip ]
JBO Runtime [ jbomt.zip jboremote.zip javax_ejb.zip jndi.jar
xmlparser.jar ]
This library information can be obtained from bin/library.ini.
