How to dispatch to a servlet
Up to now i made my dispatches to a "jsp file"(page="/index.jsp") or to an "url pattern".(page="/index")
RequestDispatcher dispatcher = getServletContext().getRequestDispatcher(page);
dispatcher.forward(request, response);Now i need to dispatch my servlet directly to a servlet like page="com.mydomain.album.postnewalbum"
is it possible to do this... If not is there any alternative way.
thank you?
i know with servlet mapping on web.xml we can do it.
But;
My servlets which are written to catch form posts are first goes to a front controller so they are just defined in web.xml...if i dispatch them to a pattern they will go infinite loop in the front controller.
So thats why i am asking if it is possible to dispatch to directly to servlet name like exmp: com.mydomain.album.catchpostdata

How can I run a servlet with Sun Java System Application Server PE 8?
I've created a package with a TestServlet.class inside, used the deploytool to create a WAR and deployed this using the autodeploy folder.
The filestructure has been generated and I find the TestServlet.class in
[installdir]\domains\domain1\applications\j2ee-modules\testProject\WEB-INF\classes\[packagefolderstructure]\TestServlet.class.
The context root is working fine, but I have no clue how I can run the servlet directly via the URL.
I've tried many things like
http://localhost:8080/testProject/TestServlet
http://localhost:8080/testProject/servlet/TestServlet
http://localhost:8080/testProject/servlet/[packagenamewithpoints]TestServlet
http://localhost:8080/testProject/servlet/[packagenamewithslashes]TestServlet
etc etc
Can somebody tell me please how to write URLs to deployed servlets? Or send me an example url and xml descriptor files?
Thanks a lot in advance!in web.xml use servlet mapping
<servlet-mapping>
<servlet-name>TestServlet</servlet-name>
<url-pattern>/doit</url-pattern>
</servlet-mapping>then use http://localhost:8080/testProject/doit -
How do we run a servlet program in eclipse
how do we run a servlet program in eclipse.
Not at all, because servlets require a servlet container. Some Eclipse plugins (Lomboz etc.) do provide integration with those.

How can I test a Servlet?
Hello!
I want to test a small part of a servlet. That part connects to a database through a DataSource which is obtained in this manner:
Context ctx = new InitialContext();
ds = (DataSource) ctx.lookup(dsLookup);
conn = ds.getConnection();Details about the servlet: runs on a WebSphere application server with db2 database. Runs on the local server in our intranet and I create a Java project in Eclipse with Create project from existing source: path to location on server.
It's really annoying to start the browser, get to the page I'm interested, make the neccesary request and then see what happens in my code.
What I've learned so far:
I can't test it in a main function because I can't get the context. I tried setting the context's properties, still no go.
I found this: http://www.ibm.com/developerworks/rational/library/08/0219_jadhav/
but I got lost when it came to adding the resource reference to the project. How can one do that in Eclipse?
Can anyone please, please, pretty please with sugar on top, explain to me how I can do this?
Thank you very much for your time,
IuliaThank you for your prompt reply. I still have some questions:
You say that configuration must go in the web.xml file. I don't have that file. In the tutorial example one application is a Java project the other is an application client and the other is an EAR of the application client. Neither of them have a web.xml file. So where do I set the resource?
Do I have to have a WebSphere application server installed on my local machine?Where and how do I run the servlet?
Thank you,

How to insert the new Servlet Api Class files?
Hi,
I need to know how do I add the Servlet Api Class to my java directory
after i download it from the net? Thanks for your help in advance!niceguyme,
If you downloaded the J2EE 1.3.1 API and installed it to (for example) c:\j2ee131, then what you need to add to your class path is:
c:\j2ee131\lib\j2ee.jar
I also add c:\j2ee131\lib\ejb10deployment.jar to the classpath, but it is not necessary.
there are several ways to add these to your classpath. It depends on what Operating System you are using. On windows 98 type OS, you can edit the autoexec.bat and add these directly to your already existing classpath. Windows NT,2000, and XP: you can add them to the system environment variables classpath. Hopefully you know how to do this on your machine. What I like to do on the windows machine is create a batch file that will start it from within a command prompt. I do this because there are times when I need to compile my code using different versions of the Java api. I am enclosing an example of one for J2se1.4.1 and j2ee1.3.1.
contents of java141.bat
@ECHO OFF
ECHO JDK 1.4.1 and J2EE 1.3.1 are current versions
set HOLD_CP = %CLASSPATH%
set HOLD_PATH = %PATH%
set CLASSPATH=.
set CLASSPATH=%CLASSPATH%;e:\jdk14\jre\lib\rt.jar
set CLASSPATH=%CLASSPATH%;e:\jdk14\lib\dt.jar

set CLASSPATH=%CLASSPATH%;e:\jdk14\lib\htmlconverter.jar
rem **** J2EE STUFF ****

set PATH=e:\jdk14\bin
set PATH=%PATH%;"C:\Program Files\TextPad 4"
set PATH=%PATH%;c:\windows\command

How to invke the XSQL Servlet directly
What I am really trying to achieve is the ability to forward an xml document to the XSQL servlet for further processing.
How can I invoke the servlet rather than go via an xsql page and what parameters do I need to pass in order for it to work.
I'm wondering out loud if the new filter capabilities of servlet 2.3 will achieve the desired effect.
Any ideas?You can get the RequestDispatcher and call forward() on it
to forward to an XSQL page. From another one of your posts
it seems you might have already figured this out. :-) -

Are you talking about caching, or working with disconnected rowsets, or both?
Anyway, look for paging taglibs, and read the documentation for javax.sql.rowset.CachedRowSet.
