Call servlet through stateless sessionbean

can any body help me about.....
code to call(run) servlet through stateless session bean,
how can develop it using URL class..
please help me............

Hi
it can be possible if your session bean can call servlet through an protocol.
means you can create an URL or URL connection class and call it through http protocol.
i .e we can create URLConnetion ( HttpURLConnection ) object to that servlet from a session bean.
I hope this will help you some extent to solve your probs.
Thanks

RuntimeException through Stateless SessionBeans causes JNDI lookup crash

Hello,
It seems there is a big problem with the RuntimeException thrown through two Stateless SessionBeans. Here is the code (without the interfaces, that are straight forward) :
public class ProcessorBean { public String process() { throw new RuntimeException("error"); } } /* This is a sub-bean that throws a simple RuntimeException */
public class OtherBean { public String hello() { return "processed by OtherBean"; } } /* Another sub-bean to test the catch-call (optional) */
public class TestBean
    @EJB
    private ProcessorLocal processor;
    @EJB
    private OtherLocal other;
    public String process()
          String result = null;
          try
              result = processor.process(); //will throws a RuntimeException
          catch(Exception e)
              result = other.hello(); //CRASH !!!! --> afther that processor.process() trhows a RuntimeException, all injections @EJB are down ! There will be a ejb.some_unmapped_exception written in the console.
          return result;
}You will find a little Enterprise project here to see the problem (just use the WebService tester in asadmin)
Note that there is no problem if an Exception that DOES NOT inherit from RuntimeException is thrown.
Maybe someone have an idea how to solve simply that problem ?
Regards,
Cedric

What is your exception exactly?
I deploeyd you jar package in JBoss 5.0, and called your facade bean with this code:
import java.util.Properties;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
import ch.capi.test.RemoteFacadeRemote;
public class MainRemoteEJBCaller {
     public static void main(String[] args) throws Exception {
          Properties env = new Properties();
          env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
          env.put(Context.PROVIDER_URL, "jnp://localhost:1099");
          env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
          InitialContext jndiContext = new InitialContext(env);
          Object ref = jndiContext.lookup("RemoteFacadeBean/remote");
          RemoteFacadeRemote facadeBean = (RemoteFacadeRemote)PortableRemoteObject.narrow(ref,RemoteFacadeRemote.class);
          System.out.println( facadeBean.test("Test") );
          System.out.println( facadeBean.testException("Test") );
}And got not errors. The output is this:
Your input : [Test] / You're saved !

Calling servlet through HttpURLConnection

hi guyz ....
I am trying to call a servlet, hosted on Tomcat/4.0.3. It is accepting two parameters. I am using the following program to call it, but it is continuously throwing exception Exception in thread "main" java.io.FileNotFoundException: http://202.141.230.246:8080/examples/servlet/AServlet. When I paste the above same url in browser, it works fine, also other servlets at the same location are working fine from my program and browser. For your convenience, the effective part of the code is given below:
      URL url = new URL("http://202.141.230.246:8080/examples/servlet/JndiServlet");
      URLConnection connection = (URLConnection) url.openConnection();
      //connection.setRequestMethod("POST");
      connection.setDoOutput(true);
      PrintWriter out = new PrintWriter(connection.getOutputStream());
      // encode the message
      String name = "s="+URLEncoder.encode("Qusay Mahmoud");
      String email = "name="+URLEncoder.encode("[email protected]");
      // send the encoded message
      out.println(name+"&"+email);
      out.close();
      BufferedReader in =
                new BufferedReader(new InputStreamReader(connection.getInputStream()));
      String line;
      while ((line = in.readLine()) != null)
         System.out.println(line);
      in.close();Exception is thrown on the line where i am creating an instance of BufferedReader class.
Any help will be of great value.

Calling servlets in tomcat 4 (path-problem)

Hi,
I have copied the IsItWorking-Servlet in webapps/examples/Web-Inf/classes.
To call the servlet through a browser I have to write:
http://server-name:8080/examples/servlet/IsItWorking .
This works fine. But ..unfortunately I have to call the servlets in the following way:
http://server-name:8080/examples/IsItWorking.
Which xml-File defines the parameter "servlet" ??

Hi,
edit the web.xml under the \examples\web-inf.
add the following
<servlet>
<servlet-name>
IsItWorking
</servlet-name>
<servlet-class>
IsItWorkingServlet
</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>
IsItWorking
</servlet-name>
<url-pattern>
/IsItWorking
</url-pattern>
</servlet-mapping>

How can I fix my phone's ringer? The call comes through but it won't ring.

I've had my iPhone for over 6 months now with no issues. I have not had it reserviced, its not refurbished, and I bought it new from an AT&T store.
This week my phone stopped ringing. The incoming call comes through on the screen, but it doesn't ring out loud so I know I'm getting a call and I can't sit and stare at my iPhone's screen all day long to see if I'm getting an incoming call. It vibrates when a call comes in maybe 20% of the time.
Today I went into settings and reset my settings but it still didn't bring my ringer back. It plays the ringers when you are looking through the list of ringers, it plays it when you alter the volume setting, but when a call is actually coming in or when I'm receiving a text message or something, no sound.
What can I do to get my ringer back?

Check the mute switch on the side above the volume rocker. If the red dot shows, the phone is muted. You'll still be able to play the ringtones to select one.
I find that the switch can be thrown to "mute" by accident when I put my iPhone in my belt holster.

How to use Transaction in Stateless SessionBean?

I want to use a transaction in a stateless sessionbean.Here is the code I am using:
public void createQuestion(QuestionModel questionModel,Collection outcomeList) throws Exception{
UserTransaction ut=getUserTransaction();
try{
QuestionHome qHome=EJBUtil.getQuestionHome();
QuestionOutcomeHome qoHome=EJBUtil.getQuestionOutcomeHome();
ut.begin();
QuestionRemote qr=qHome.create(questionModel.getName(),questionModel.getContent(),questionModel.getCreatorId());
Long id=qr.getQuestionModel().getId();
Iterator outcomes=outcomeList.iterator();
while(outcomes.hasNext()){
QuestionOutcomeModel qom=(QuestionOutcomeModel)outcomes.next();
QuestionOutcomeRemote qor=qoHome.create(id,qom.getValue(),qom.getFeedBack());
ut.commit();
}catch(Exception e){
ut.rollback();
throw new Exception(e);
private UserTransaction getUserTransaction() throws NamingException{
UserTransaction ut=null;
try{
InitialContext ic = new InitialContext();
ut = (UserTransaction) ic.lookup("UserTransaction");
} catch (NamingException ne) {
throw new EJBException(ne);
return ut;
And In the entity bean,I define a XADatasource:
private Connection getXADBConnection() throws SQLException {
Connection connection;
try {
InitialContext ic = new InitialContext();
DataSource ds = (DataSource)
ic.lookup("java:/MSSQLXaDS");
connection = ds.getConnection();
} catch (NamingException ne) {
throw new EJBException(ne);
} catch (SQLException se) {
throw new EJBException(se);
return connection;
When I run the code, it throws the following Exception:

Call Transaction Through RFC

Hi ,
I am trying to do a call transaction through RFC call from a Middleware which is a CPIC user (only communication Non dialog User ) .
Call transaction does gets executed without any error but it does not update any data.But when I run it through my user id it works absolutely fine .
I am not sure what is causing the issue
Security authorization?
RFC through Non Dialog user ?
Paramters missing in RFC ?
Paramatertes missing in call transaction option?
If anyone of you has faced a similiar issue then please let me know the path forward.
Thanks
Vikas

Hi Vikas,
The problem is in Authorization? And check the mode of Process Synchoronus or asynchoronous? Both the RFC and CALL transaction should be Same /
Thanks

Pass query to servlet through midlet

Hi, I have a problem here. I would like to control the SQL Statement to be executed by the servlet using the mobile midlet. Like this one:
midlet -> will call servlet with parameter statement -> servlet will execute the statement parameter passed by the midlet and will return a data result in XML -> midlet will read the XML file and retrieve the data.
Another thing I would like to ask is how will I make the servlet to output an XML file that can be read by the midlet. If there's some tutorial on how please give me the link.
I hope you get my point.

I have made to retrieve data on my midlet from my servlet. The bad thing is the data sent on the midlet has html tags. How will I make the midlet to just output the data result without the tags?If you are in charge of the servlet, then have it output plain text. If you need to parse the MIDlet input first, then having the content of XML/HTML elements will allow you to print them out.
Is this servlet used from HTML browser as well? If so, try having a separate one for mobile devices. There are plenty options to do it.

You may want to investigate the built in java.net.URL class. For advanced needs, Apache has a Java HTTP client library.

You have to establish a URLConnection with servlet from your java program.
URL servletURL = new URL("http://localhost:8080/Myservlet?str1=abc&str2=def");
URLConnection servletConnection = servletURL.openConnection();you can get the objectOutputStream
ObjectOutputStream oos = new ObjectOutputStream (servletConnection.getOutputStream());
oos.writeObject(your file object);-------------------------------------------------
In the servlet u can get the strings using request.getParameter("str1");
In the servlet u can get the strings using request.getParameter("str2");
file = new ObjectInputStream (request.getInputStream()).readObject()a lot of resources are available on this ...
hope this helps :)
