Can we call a simple java application from ESB

Please let me know how this can be done by using a ESB. The application jar exists on the host server. How we can pass parameters etc and receive results from this application.
Any help will be greatly appreciated.
Prakash

Not sure if I completely understand your question, but you can certainly try following ways:
- call your java application via WSIF. ESB with JAVA wsif is available in 10.1.3.3.1 only (it is not supported in 10.1.3.3 very well).
- you will have to include this jar file in server.xml or bpel/system/classes so that it is available to the SOA jvm.
- You mentioned it is simple java application, but if your java API has complex (object) input and output, you will need some work

How to call a WD JAVA application from a WD ABAP application

Hi experts,
Here I have two applications with me. One has been created through WebDynpro ABAP while the other one has been created through WebDynpro JAVA. Now i have to call upon the JAVA aplication from my ABAp application. In other words in need to integrate both the applications so as to have an easy navigation in between them.
In the whole process I need to take care that the data is not lost from both ABAP or JAVA side.
Please help me someone knows the solution.
Regards,
Kaustubh Maithani

Hi,
Usally to run WebDynpro for Java Application, we get the Application URL.
If you want to call this WebDynpro Java Application from Webdynpro Abap, then create UI element like Link to Action or LinktoURL and give the url as WebDynpro for Java URL.

How do I call a simple java class from a bpel process?

Hi.
In JDeveloper 10.1.4.3.0 I've created a simple java class that does an ftp get operation followed by an unzip. The class uses some 3rd part libraries (jars).
I want to use a simple bpel process to schedule a daily execution of this java class, and deploy it all to our SOA-server, - and was looking into using the <bpelx:exec> function.
The java class and the bpel process is all stored in the same JDeveloper project.
How do I put this together so that both my java class and the necessary jars are available to the bpel process?
I've looked into the JavaExecSample.bpel, and it's says something about "...the class com.otn.samples.javaexec.CreditCalculator is locally packaged with this BPEL process".
How do I do that?
Can I make it and test it all locally from my workstation (only JDeveloper installed, I guess there's nothing that can execute the bpel code?), or do I have to compile class etc (make war-file?) and deploy to SOA server (BPEL-INF/lib or classes?) before anything can be tested?
(I guess all this is simple, once you know how, but being a newbie to this I need a shove in the right direction :-)
Regards,
-Haakon-

To create a java class and dependent jars inside the BPEL process project you need to do the following:
1. Right click on your BPEL process project and select New and then Java Class from the Items.
2. Make the BPEL process project, JDeveloper would compile the java classes and add them into the BPEL suite case jar, see the output folder and check the BPEL suite case jar file for java classes and dependent jars.
You can test your Java classes from JDeveloper IDE, no need to deploy the classes on SOA server. When you make the BPEL project it compiles .bpel files and Java classes. You can test your classes once .bpel file and java classes compiled successfully.

You can achieve this using LiveCycle PDF Generator JAVA API. You can find required code here:
Adobe LiveCycle * Quick Start (SOAP mode): Converting a Microsoft Word document to a PDF document using the Java API
In parameters:
//Set createPDF2 parameter values
String adobePDFSettings = "Standard";
String securitySettings = "No Security";
String fileTypeSettings = "Standard OCR";
"Standard OCR" file type setting will run OCR on input pdf. In the code, instead of doc file provide a pdf file. Resultant pdf will be searchable PDF i.e OCRed PDF.
Feel feel to ask any further questions.

Calling Webdynpro Java Application from Webdynpro ABAP Application.

Hi,
We have developed one Application using Webdynpro Java and I m in need to call the Webdynpro Java application from Webdynpro ABAP.
Require Suggestions to acheive this.
Thanks In advance.
Reg,
Ajay.

Dear Ajay,
Assuming that both your applications WDA & WDJ are in the portal & you don't have to pass any parameters to the WDJ application.
Write the following code on the action where you would call the WDJ application.
DATA:
        lr_compcontroller TYPE REF TO ig_componentcontroller,
        l_component TYPE REF TO if_wd_component ,
        lr_port_manager TYPE REF TO if_wd_portal_integration ,
        wa_navigation TYPE navigation.
lr_compcontroller =   wd_this->get_componentcontroller_ctr( ).
l_component = lr_compcontroller->wd_get_api( ).
lr_port_manager = l_component->get_portal_manager( ) .
* The value inserted into the navigation-target field can be found in the Portal
* content administration tab of your portal. It is the ID or PCD Location field
wa_navigation-target = pcd. " Please provide the PCD Location of the WDJ Application here.
wa_navigation-mode   = '0'. "0 = INTERNAL(same page) and 1 = EXTERNAL(new page).
CALL METHOD lr_port_manager->navigate_absolute
    EXPORTING
      navigation_target = wa_navigation-target
      navigation_mode   = wa_navigation-mode.
You can get the PCD from the Page properties of the WDJ application page in the Portal.
Hope it helps!
Warm regards,
Upendra Agrawal

Calling simple Java Code from 11g BPM

Hi,
I know this has been round the houses but I cant find a satisfactory solution for my scenario. I would like to call some simple java code from BPM (11.1.1.6). I guess I need to expose it as a service but it seems overkill to be via soap so any advice you can give would be much appreciated. Creating a jar that I can call somehow would be perfect.
This is my scenario:
- I am creating a Security POC for BPM
- The BPM Process is exposed as a web service and authenticated using SAML
- I am testing by calling the WS from OSB
- I want to be able to get the WLS Principal and display the username and the roles for the launching user, from within the BPM process
- This is possible using some simple weblogic client api code shown below
- So all I want to do is call this code from BPM somehow
- Anyone point me in the right direction ?
cheers
Tony
subject = Security.getCurrentSubject();
for(Principal p: subject.getPrincipals()) {
if(p instanceof WLSGroupImpl) {
groupList.add(p.getName());
} else if (p instanceof WLSUser) {
principal = p.getName();
}

Can we run the batch file using simple java application

Hello sir,
we want to run the batch file using simple java application. i tried with some example, we run the exe files but not batch file.
Runtime r = Runtime.getRuntime();
r.exec("D:\\jboss\\bin\\run.bat");
My application is server will run when we run the java appliation.
any suggestion? plz give me the solutions

yes you can run html file
WEB.SHOW_DOCUMENT is a built-in that is used in Forms to call URL from a Web Form. It works much like the similar way that a link on an HTML page works and it takes two arguments, one is URL and second one is TARGET, in your case use following.
WEB.SHOW_DOCUMENT('http://channas.iil.informatics.lk:8890/forms/frmservlet?config=abc.html', '_blank');
Hope this will work for you

Call a Java Application from MicroFocus COBOL (in UNIX environment)

Hello,
Could you please let me know, how to call a Java application from a MicroFocus COBOL application. If anyone has any code samples, that would be of great help.
Thanks in advance,
Tijo.

You generally can't cause a program to be executed on a different >server. Basic security, you know. Besides this idea of having the Java >application run on a different server wasn't mentioned in your original >post. That leads me to believe we don't have the whole story.So I think you need to step back and find out what are the requirements. For example: Does your program need to start this Java application running, or is it already running and your program needs to connect to it somehow?
My program has to start a Java class file, meaning that the Micro Focus COBOL module will call the Java class file. Will it be running on the same machine as your program, or on some other machine?
For both cases, I would like to know the answer.a) Running on the same machine as my program is running.
b) Running on the different machine.
And then there are the questions about whether your program needs to have a conversation with the Java application, or whether it just needs to start it and that's all.
COBOL program has to call a Java class by passing some parameters and Java class in turn process it and return some value back.. Kind of Request and Response model.Plenty of questions to be asked. Go and find out what they are.
Sorry ... if I am not clear on my questions. Anyhow, thank you very much for providing the information.

Calling Java application from servlet

Hi !
I'm trying to run a Java application from within a servlet with Tomcat 4. I'm using the Runtime.getRuntime ().exec () method. So the application is run in a different JVM as a subprocess of the servlet. I use ObjectInputStream and ObjectOutputStream and a serializable object to enable communication between the servlet and the application.
I tested the application and the serializable object with another Java application that works as the caller and it works fine. However, replacing the caller application with the servlet I get a StreamCorruptedException. The structure of the caller application and the servlet is the same.
My questions are:
- Is there something I should configure in Tomcat to create a subprocess ?
- What is the cause of the StreamCorruptedException ? How do I get it with the servlet and not with the application ?
- Should I use an environment with the call to Runtime.getRuntime ().exec () ? How do I use it ?
- Is the called application forced to run in my servlet's context ?
- Is there a better way to do this ?
Thanks to all

Here's my code:
1. The serializable object:
// Object Obj
import java.io.*;
public class Obj implements Serializable
public int n;
public Obj ()
n = 0;
public Obj (int n)
this.n = n;
public String toString ()
return getClass ().getName () + " -> (n = " + n + ")";
2. The application Sub (subprogram)
// Application Sub
import java.io.*;
public class Sub
private static File f;
private static FileWriter fw;
public static void main (String [] args)
throws IOException, InterruptedException, ClassNotFoundException
ObjectInputStream ois;
ObjectOutputStream oos;
Obj obj;
ois = new ObjectInputStream (System.in);
obj = (Obj) ois.readObject ();
f = new File ("Sub.txt");
fw = new FileWriter (f);
fw.write (obj.toString ());
fw.close ();
oos = new ObjectOutputStream (System.out);
oos.writeObject (obj);
ois.close ();
oos.close ();
3. The application AMain (caller application)
// Application AMain
import java.io.*;
class AMain
private static File f;
private static FileWriter fw;
public static void main (String [] args)
throws IOException, ClassNotFoundException
Runtime r;
Process p;
ObjectInputStream ois;
ObjectOutputStream oos;
Obj obj, obj2;
r = Runtime.getRuntime ();
p = r.exec ("java Sub");
oos = new ObjectOutputStream (p.getOutputStream ());
obj = new Obj (5);
oos.writeObject (obj);
oos.flush ();
B.comunica (obj);
System.out.println ("AMain sends to Sub: " + obj.toString ());
try
p.waitFor ();
catch (InterruptedException e)
System.out.println ("Subprogram was interrupted");
System.out.println (e.toString ());
ois = new ObjectInputStream (p.getInputStream ());
System.out.print ("Sub sends to AMain: ");
obj2 = (Obj) ois.readObject ();
System.out.println (" " + obj2.toString ());
oos.close ();
ois.close ();
p.destroy ();
4. The servlet SMain (the calling servlet)
// Servlet SMain
import javax.servlet.*;
import javax.servlet.http.*;
import java.sql.*;
import java.io.*;
import java.util.*;
public class SMain extends HttpServlet
public void doPost (HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
Runtime r;
Process p;
ObjectInputStream ois;
ObjectOutputStream oos;
Obj obj, obj2;
int state, i;
res.setContentType ("text/html");
ServletOutputStream out = res.getOutputStream ();
out.println ("<html>");
out.println ("<head><title>Sub</title></head>");
out.println ("<body>");
out.println ("Invoking subprogram...");
out.println (" ");
try
r = Runtime.getRuntime();
p = r.exec ("java -cp .;c:\\Programs\\Apache~1.0\\webapps\\SMain\\WEB-INF\\classes Sub");
out.println ("...invoked ");
oos = new ObjectOutputStream (p.getOutputStream ());
obj = new Obj (5);
oos.writeObject (obj);
oos.flush ();
out.println (" SMain sends to Sub: " + obj.toString () + " ");
try
p.waitFor ();
catch (InterruptedException e)
out.println (" Subprogram was interrupted ");
out.println (" " + e.toString () + " ");
state = p.exitValue ();
out.println (" Subprogram state: " + state + " ");
ois = new ObjectInputStream (p.getInputStream ());
out.print (" Sub sends to SMain: ");
obj2 = (Obj) ois.readObject ();
p.destroy ();
catch (SecurityException e)
out.println (" SecurityException ");
out.println (" " + e.toString () + " ");
catch (IOException e)
out.println (" IOException ");
out.println (" " + e.toString () + " ");
catch (Exception e)
out.println (" Exception ");
out.println (" " + e.toString () + " ");
out.println ("</body>");
out.println ("</html>");
So, as you can see, both application AMain and servlet SMain invoke application Sub and pass it the serializable object Obj. Oddly enough, application AMain works fine whereas servlet SMain throws a StreamCorruptedException exception.
johnpoole said:
�It's hard to guess what would cause the exception without seeing code, but the interaction between the processes would differ from that between two applications, because the servlet process is started with a different class loader. I'm not sure which one the jvm started by the call would use.�
How can I enforce that a System classloader be used in the call to Runtime.getRuntime ().exec () ? (I mean by System classloader a classloader equals to the one applications are launched from console).
johnpoole said
�Is there a reason why you aren't starting the second process manually and then connecting to it on a port?�
The idea is providing a Web interface for an application running in the server. The servlet is used to restrict access to this application but once access is granted (passing the servlet) the application should not be constrained.

Calling Java Application from another

How can i call a Java Application from another java App.
eg., If my Java application is called MyApp and i would like call another java application from within it.
One way could be by using "System". I would like to know if there is any other method and is portable.
Thanks in advance.

hi,
it works and not!
if you start an other class with a command like this the 2nd prog/class terminates too if you terminate the caller-class!

Calling a java application from j2ee web application

Hi,
I have a j2ee application in which i am making a call to a jar file which is a java application.
Runtime a4 = Runtime.getRuntime();
Runtime a = Runtime.getRuntime();
String cmd[] = new String[14];
cmd[0] = "cmd";
cmd[1] = "/c";
cmd[2] = "start";
cmd[3] = "javaw";
cmd[4] = "-jar";
cmd[5] = CATALINA_HOME+"\\webapps\\AveksaTesting\\AveksaTestingJava\\dist\\AveksaTestingJava.jar";
cmd[6] = SERVER_TESTS;
cmd[7] = COLLECTOR_TESTS;
cmd[8] = SYSTEM_TESTS;
cmd[9] = CREATE_ORACLE;
cmd[10] = DB_NAME;
cmd[11] = DB_DUMP;
cmd[12] = email;
cmd[13] = isMIGRATE;
try{
java.lang.Process p = a.exec(cmd);
Now in the called java application, i am first shutting down the tomcat server by calling shutdown.bat script and then starting it using startup.bat. But the problem i am facing is when i restart the server from java application, it says address already in use(i.e. port 8445 on which tomcat is runninng).
Id i just call the java application and do the same operation it works fine. I guess when i am calling java from j2ee application, j2ee still has some threads holding java and not shutting down tomcat properly.
Can anyone suggest me what can be done in this case. I have to call a java application from j2ee and restart the tomcat server many times.
Thanks in advance
