Servlet calling another servlet

hi,
I am writing a web-application which requires one servlet (on main server) to call another servlet (on a remote server).
The main servlet needs to call the remote one and send some parameters to it.
The remote servlet would be sending back XML data which is to be used by the central servlet. I tried using XML-RPC but it does'nt seem to support sending in NATIVE XML data.
I also tried by creating URL, but did not find a way to add parameters to it !!!
Could anyone please tell me how to call another servlet (along with sending POST/GET parameters) and get the results back into the calling servlet ?
Any suggestions would be greatly appreciated.
Thanks !
Ajoy

one possible solution would be to create an own socket connection (this would be a like a Post request) and than exchange data as you like.

I want to send a response from the servlet and then call another servlet.

Hi,
I want to send a response from the servlet and then call another servlet. can this happen. Here is my scenario.
1. Capture all the information from a form including an Email address and submit it to a servlet.
2. Now send a message to the browser that the request will be processed and mailed.
3. Now execute the request and give a mail to the mentioned Email.
Can this be done in any way even by calling another servlet from within a servlet or any other way.
Can any one Please help me out.
Thanks,
Ramesh

Maybe that will help you (This is registration sample):
1.You have Registration.html;
2.You have Registration servlet;
3.You have CheckUser servlet;
4.And last you have Dispatcher between all.
See the code:
Registration.html

Servlets calls another servlet

servlets calls another servlet ...how to do it ? whats the efficient way ?
class myservlet extends HttpServlet
// i want to call a servlet situated at another machine in the LAN whose, IP // 123.123.45.66 (say)
the servlet which is situated in another machine
remoteservlet extends HttpServlet
doPost(...)
how do i call ?
few of the way i found by searching the forum.
but i would like to know the good way in my situation.

res.sendRedirect("LoginServlet?="+req.getRequestURI())
i tested this. it does not work.
my servlet wants to call another servlet which is
active on IP xxx.ddd.ffff.zzz in the LAN .
whats the way ?
res.sendRedirect("http://xxx.ddd.ffff.zzz:<portnumber>/<context_name>/<servlet_regd_name">);The request and response objects are generated anew for that Servlet. There's no two ways about it, IMO.
cheers,
ram.

How to call another program as root in servlet

In my servlet, I want to call another background programs (writeen in c) to do some tasks and gather the output of them as the output of my servlet. Is there any way to do so like Suexec in apache.

sorry I forgot mention that the c program required the caller had root privilege.This is the problem I facing now.
Thanks

Calling another java class from a servlet

I am trying to write a web based form handling system (for a college project)
I have a servlet that responds to a user request for a form. I have another java program (HTMOut) that parses the xml file for the form and produces HTML output. When I call the HTMOut from the servlet it crashes the webserver (Tomcat). But if I call HTMOut from an ordinary java class it runs fine. If I call another test program from my servlet that works too.
Any ideas?

where does your HTMOut output? A file or a stream? I think it is better that HTMOut can output to a stream you can set externally.

How to calling another servlet in a servlet

In my servlet named TransferServlet I want call another servlet named PublisherServlet. So I wrote codes :
objURL = new URL("http://localhost:8080/servlet/PublisherServlet") ;
hucConnection = (HttpURLConnection)objURL.openConnection() ;
hucConnection.setDoOutput(true) ;
hucConnection.setUseCaches(false) ;
hucConnection.setRequestMethod("POST") ;
hucConnection.connect() ;
but i can't invoke PublisherServlet. Why ? pls help
Thanks a lot

you do not need hucConnection.connect(); hucConnection = (HttpURLConnection)objURL.openConnection() does this.
You need to use hucConnection.getOutputStream() and write to the stream to post and if you wanted a response you would need to read from hucConnection.getInputStream()

Calling another servlet from a servlet

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:

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.

Servlet Calls another Servlet, Returns an Object

Is it possible to call another servlet (which is loaded through
          Load-on-startup) from another servlet. The return should be an Object.
          I know I am kind of asking for a procedural way of programming.
          Example : Servlet "IamReady" is loaded and gets a request with binary
          data. It replies with a Binary Object.
          Servlet "serviceCall" calls IamReady to get the resoponse.
          I know that there are forward (using requestDispatcher) and "include"
          directives to have another servlet service calling servlet.
          Also, if I define a method in the (generic servlet) does each call to
          methos is executed in different thread (like doPost and doGet).
          Thanks.
          Chris

          Are you suggesting I should just have a class. Reason I have it as
          servlet, b'caz I do a load-on-startup and do initialiazation etc. in
          the init method. May be if you suggest how I can do it otherwise, I
          would like to implement it that way.
          Thanks again.

Question about the sensor... just got my 4s yesterday after screwing up my 3 with the laterd version update. EVery call I have been on has either changed to speaker, called another number or ended the call or activated facetime, which I have turned off.

Question about the sensor... just got my 4s yesterday after screwing up my 3 with the laterd version update. EVery call I have been on has either changed to speaker, called another number or ended the call or activated facetime, which I have turned off. never had this trouble with my 3...I don't even want to talk to anyone on this phone! Is the sensor bad? That is what the AT&t rep suggested.

Restore as new... if the problem still continues then there is a hardware issue.
If it stops after a restore as new, then the issue is with the backup the device is currently setup with.

Local Session Bean calling another local Session Bean in EJB 3.0

Hi,
In EJB 3.0, I am trying to do JNDI lookup of a local sesion bean from another session bean's helper class.
I am not using @EJB injection mechanism here, as call to the local session bean is made in a helper class. Helper classes do not support resource injection.
Following are the EJB class definitions used in my project. Call to "EJB3Local" made from "EJB1" fails as the "EJB2" helper class is calling "EJB1Local"
@Stateless
@EJBs({@EJB(name="EJB2Local", beanInterface=EJB2Local.class),
@EJB(name="EJB3Local", beanInterface=EJB3Local.class)})
public class EJB1 implements EJB1Remote, EJB1Local{
public void findEJB3Local(){
//1. JNDI lookup for EJB3Local ----
//2. EJB3Local.someFunction()
@Stateless
@EJB(name="EJB1Local", beanInterface=EJB1Local.class)
public class EJB2 implements EJB2Remote, EJB2Local{
public void findEJB1Local(){
//1. JNDI lookup EJB1Local
// 2. Call EJB1Local.findEJB1Local method
@Stateless
public class EJB3 implements EJB3Remote, EJB3Local{
public void someFunction(){}
A remote call to EJB2.findEJB1Local() will invoke EJb1Local.findEJB3Local method and the call fails with "java:comp/env/EJB3Local" not found in EJB1Local.
Has anybody encountered an issue like this issue with local interface calling another local interface?
Thanks,
Mohan

To refer a Ejb from another Ejb include <ejb-ref> element
in ejb-jar.xml
<session>
<ejb-name>SessionBeanA</ejb-name>
<ejb-ref>
<ejb-ref-name>SessionBeanB</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<home>com.ejb.SessionBeanBHome</home>
<remote>com.ejb.SessionBeanB</remote>
</ejb-ref>
</session>
Include a <reference-descriptor> in weblogic-ejb-jar.xml
<weblogic-enterprise-bean>
<ejb-name>SessionBeanA</ejb-name>
<reference-descriptor>
<ejb-reference-description>
<ejb-ref-name>SessionBeanB</ejb-ref-name>
<jndi-name>com.ejb.SessionBeanBHome</jndi-name>
</ejb-reference-description>
</reference-descriptor>
</weblogic-enterprise-bean>
In SessionBeanA Bean class refer to SessionBeanB with
a remote reference to SessionBeanB.
InitialContext initialContext=new InitialContext();
SessionBeanBHome sessionBeanBHome=(SessionBeanBHome)
initialContext.lookup("com.ejb.SessionBeanBHome");
SessionBeanB sessionBeanB=sessionBeanBHome.findByPrimaryKey(primarykey);
sessionBeanB.update();
sessionBeanB.getAll();

I am new to web dynpro. And I am working on several web dynpro applications. I just want to know how to call another web dynpro within a web dynpro application. Don't use popups, I'd like the web dynpro work together in the same window just like a wizard.
Thanks a lot.

Hi Guo,
Yes, you can achieve it by Component Usage. You can embed other component's Interface views into your own Windows. Check out the component Usage information in help.sap.com to get a clear idea of it.

PHP script calling another but staying on same page

Hi,
Im thinking of writing an additional PHP page, that has a link to another PHP page, to do an insert. On the current PHP page, I have a counter which I would want incrementing after the 2nd PHP script is called, but don't think its possible?
I'm saying this as I will need an anchor to another script which when called, will load another PHP script - which will do the insert, but take me away from the current page.
So basically, I want to stay on the first PHP script showing a counter, click to call another PHP script, but all the user will see is a counter increment.
Here is what I have thought will not work:
<code>
echo "<br><span class=\"style1\"><a href=\"./../Test/count.php\"><img src=\"./Up.JPG\"></a>";
</code>
Thanks in advance...

Hi,
got a bit further now in that i'm calling the php script through Ajax successfully, but, got the issue where i am getting the same value sent to the script (dataString):
source script:
<script type="text/javascript" >
$(function()
$(".submit").click(function()
var likeid = $("#likeid").val();
var dataString = 'likeid='+ likeid ;
var locurl = "./../Test/it.php?randval="+Math.random();
$.ajax({
   type: "POST",
   url: locurl,
   data: dataString,
   success: function()
    $('.success').fadeIn(200).show();
    $('.error').fadeOut(200).hide();
return false;
</script>
target script (it.php)
<?php if(!$_SESSION) { session_start(); } ?>
<html xmlns="http://www.w3.org/1999/xhtml">
<html>
<head>
</head>
<body>
<?php
$_SESSION['name']=session_id();
$sess=session_id();
$likeid=$_POST['likeid']; <----------------------always the same value
if($_POST)
$result2 = mysql_query("INSERT INTO Test (value, sess) VALUES ('$likeid', '$sess')")
or die(mysql_error());
?>
</body>
</html>
what i get is the same value for $likeid on every call from the source script. In the source script i have:
<form method="post" name="form1">
<input type="hidden" name="likeid" id="likeid" value="CAR79668"/>
<a href="#"><img src="./Up.JPG" border="0" class="submit" onclick="change11('CAR79668');"></a>
<b id="CAR79668" value="2">2</b> </form> </span>
<form method="post" name="form2">
<input type="hidden" name="likeid" id="likeid" value="CAR79669"/>
<a href="#"><img src="./Up.JPG" border="0" class="submit" onclick="change11('CAR79669');"></a>
<b id="CAR79669" value="2">2</b> </form> </span>
Why does the same value of CAR79668 get passed to the target script on every call?
Thanks.

How to call another form ,if option is entered in a text item object ???

hi ,
I am created an application ,where in i press a button which call another form having a menu .
I select any one of the option from the menu ....i enter a number in the text item object of this form ....depending upon what option i have typed .....i would like to call another form ...
My questions are
1) Which trigger of this text item should be enabled,and what code to i write in this trigger ?
2) Since this form is not having any database insert,delete ,update or query (select)
it should directly go to the new form,whose option i provide in the text item .
Sunny

hey bro, i am assuming that ur text item contains the form name, any relevant trigger can be used for user action, like key-enter, post-change or key-next-item.
to run a form u can use functions call_form or open_form with proper paramters.
if u want to forward the entered text in the item, use global variable for the session.
it doesnt matter if the form contains database items or blocks, all u have to do is run the form.
e.g,
declare
VAR VARCHAR2-------;
begin
/* u can use the variable to concatinate or modify too, also can use global variable
var:=:urblock.uritem;
/* use ur own relevant parameters */
open_form(VAR,ACTIVATE,NO_SESSION);
exception
when---------
end;

SOMETHING LIKE THIS---
WHEN others then
     insert_costing(in_period, in_project_id, in_user_id ,in_thu,in_fri,in_sat,in_sun,in_mon,in_tue,in_wed ,in_submit);
COMMIT;
END update_costing;

begin
UPDATE statement
IF SQL%ROWCOUNT =0
then
INSERT statement|procedure
end if;
end;
/Hi,
i have a simple doubt over here, i read somewhere that cursor attributes can be used only as long as the cursor is open, then in the above case whiel doing the update operation, oracle implicitly will open an cursor and will do the operation and then will close the cursor, then how does SQL%ROWcount works???please revert...
