Unable to call Java class method within Embedding Java Activity in BPEL

Hi ,
I have written Java Class named 'Class3' .
When I am creating and trying to call these classes whithin Embedding Java Activity , compile time error is coming. Compiler is not finding class . Error message is like this one.

Hi ,
In your java project frm jdev..right click and choose general and then choose deployment profiles and then choose Jar ..and then give some appropriate name(abc) and then click ok.
Then under resources file u get a abc.deploy file right click and say deploy to jar ..u will find the jar in that director.Now include this jar in your prjct libraries.
have a look at the link http://niallcblogs.blogspot.com/search/label/embedded%20Java

How to call inner class method in one java file from another java file?

hello guyz, i m tryin to access an inner class method defined in one class from another class... i m posting the code too wit error. plz help me out.
// test1.java
public class test1
     public test1()
          test t = new test();
     public class test
          test()
          public int geti()
               int i=10;
               return i;
// test2.java
class test2
     public static void main(String[] args)
          test1 t1 = new test1();
          System.out.println(t1.t.i);
i m getting error as
test2.java:7: cannot resolve symbol
symbol : variable t
location: class test1
          System.out.println(t1.t.geti());
^

There are various ways to define and use nested classes. Here is a common pattern. The inner class is private but implements an interface visible to the client. The enclosing class provides a factory method to create instances of the inner class.
interface I {
    void method();
class Outer {
    private String name;
    public Outer(String name) {
        this.name = name;
    public I createInner() {
        return new Inner();
    private class Inner implements I {
        public void method() {
            System.out.format("Enclosing object's name is %s%n", name);
public class Demo {
    public static void main(String[] args) {
        Outer outer = new Outer("Otto");
        I junior = outer.createInner();
        junior.method();
}

Read through your text book or some java tutorials from this site to understand what classes are, what are methods, etc.
Your program is full of wrong initializations (as you rightly said you dont understand how to call up class method I would add that you dont understand how to call classes and what do they return e.g.
You have declared
String p;
then you go ahead and do this
p = new Product("manuf","name","quantity","price"); This is syntax for calling a class is this class returning a String? :s
Please go through the basics of Object Oriented Programming and then start with the coding part else you will face such very many difficulties and waste more time of yours in just coding with no results.
Look for the tutorials on this site and read through them and do example as given in them.

How to write javascript in java class method

Hi,
any one please resolved this,
i want to write javascript window closing code into java class method, in that method i want to write javascript code & wanted to call in jsf page on commandButton action event,
my code is below but it is not working properly
public void closeWindowClicked(ActionEvent event) {
 try
 FacesContext facesContext = FacesContext.getCurrentInstance();
 String javaScriptText = "window.close();";
 // Add the Javascript to the rendered page's header for immediate execution
 AddResource addResource = AddResourceFactory.getInstance(facesContext);
 addResource.addInlineScriptAtPosition(facesContext, AddResource.HEADER_BEGIN, javaScriptText);
catch(Exception e)

for calling into jsf code is below
<h:commandButton action="#{parentBean.closeWindowClicked}" value="OK" />
/*Note- i want to closed the window by caling method contain javascript only, i don't want any ajax code in method */
please any one can resolved this.
Thanks

/*Note- i want to closed the window by caling method contain javascript only, i
don't want any ajax code in method */ When the user presses your button, do your business logic and then send them to a page containing the following (note: untested code ahead):
<html>
<head>
 function onLoadHandler()
 window.close();
</head>
<body onload="onLoadHandler();">

Invoking remote java classes/methods

Hi,
I just wanted to ask for opinions and suggestions regarding my attempt to call a remote java class method using PL/SQL. I didn't want to load it in the database since the configurations for the java class were already set using Spring Integration. I just wanted to supply constructor arguments and run the method and then retrieve the result. Are there any good or easier ways on doing this?
Thanks in advance

Very curious Susan,
A server JVM might not want to host mobile code from other clients, not that it's unsafe, it's just that it allows clients to crash the server JVM at will. They should have it configured to automatically restart though.
Did they delete the java.rmi.* packages from the server JVM runtime? I don't understand why they'd do that.
If you can pry some reasons from them, I'd be very interested to hear them. Perhaps they just want more money, in order to allow you this privilige.

Is it possible to call a class method using pattern in ABAP editor.

Hi,
Is it possible to call a class method using pattern in ABAP editor.
Thank U for Ur time.
Cheers,
Sam

Yes,
Click patterns.
Then choose Abap objects patterns.
Click on the Tick
It will give a new screen
Here Give the name of the class first.
Then the object (instance of the calss)
And finally the method ..
it will give you the pattern
Hope this helps.

How can I call a java class from within my program?

I was wondering if there's a platform independent way to call a java class from my program.

Here's my scenario. I'm working on a platform independent, feature rich, object-oriented command prompt program. The way I'm designing it is that users can drop classes they write into my bin directory and gain access to the class through my program. For example, they drop a class named Network.class in the bin directory. They would type Network network at my command prompt and gain access to all the methods available in that class. They can then type system.echo network.ipaddress() at my prompt and get the system's ip address. I have it designed that there's a server running in the background and the clients connect to my port. Once connected the end-user can enter their user name and password and gain access to the system. When they type a command they actually call another java program which connects to my server using a seperate thread. They can then communicate back and forth. I have it set that everything has a process id and it's used to keep track of who called what program. Once the program is done it disconnects and closes. Rather than getting into the nitty gritty (I didn't want to get into heavy detail, I know how everything will work) I'm really interested in finding out how I can call a java program from my program. I don't want it to be part of the app in any way.

Calling ABAP class methods from JAVA application

Hi All,
I want to fetch ITS related information (SITSPMON Tcode) in my JAVA application. But i didnt find much BAPIs for the same. While debugging I came accross few class methods with help of which I can get the required information. So is there any way we can call and execute methods of ABAP classes through java application?
for e.g. I want to call GET_VERSION method of CL_ITSP_UTIL class.
Thanks,
Arati.

Hi,
Yes, as per my knowledge the only way to interact is using BAPI exposed as RFCs. So try to invoke those class methods in one CUSTOM BAPI and expose that BAPI as RFC and consume that RFC to get those details.

Charan

Unable to call the RFC from the WD java Program

Hi All,
I have a table and three buttons Create, Edit, Save in the layout.
If no record available in the R3 the the end user will click on create and then he will click on save so that the insert RFC will be called accordingly and the record will be inserted.My table is limited to 5 records only. If i enter all the 5 records and Click on submit the record is inserting in the backend , but if i enter less than 5 records im unable to call the RFC what might be the issue.
My insert RFC takes one Table node and 4 import parameters i'm passing all of the all the mentioned import parameters.

Unable to call exported client methods of EJB session bean remote interface

I am unable to call client methods of a BC4J application module deployed as a Session EJB to Oracle 8i at the client side of my multi-tier application. There is no documentation, and I am unable to understand how I should do it.
A business components project has been created. For instance, its application module is called BestdataModule. A few custom methods have been added to BestdataModuleImpl.java file, for instance:
public void doNothingNoArgs() {
public void doNothingOneArg(String astr) {
public void setCertificate(String userName, String userPassword) {
theCertificate = new Certificate(userName, userPassword);
public String getPermission() {
if (theCertificate != null)
{if (theCertificate.getPermission())
{return("Yes");
else return("No, expired");
else return("No, absent");
theCertificate being a protected class variable and Certificate being a class, etc.
The application module has been tested in the local mode, made remotable to be deployed as EJB session bean, methods to appear at the client side have been selected. The application module has been successfully deployed to Oracle 8.1.7 and tested in the remote mode. A custom library containing BestdataModuleEJBClient.jar and BestDataCommonEJB.jar has been created.
Then I try to create a client basing on Example Oracle8i/EJB Client snippet:
package bestclients;
import java.lang.*;
import java.sql.*;
import java.util.*;
import javax.naming.*;
import oracle.aurora.jndi.sess_iiop.*;
import oracle.jbo.*;
import oracle.jbo.client.remote.ejb.*;
import oracle.jbo.common.remote.*;
import oracle.jbo.common.remote.ejb.*;
import oracle.jdeveloper.html.*;
import bestdata.client.ejb.*;
import bestdata.common.ejb.*;
import bestdata.common.*;
import bestdata.client.ejb.BestdataModuleEJBClient;
public class BestClients extends Object {
static Hashtable env = new Hashtable(10);
public static void main(String[] args) {
String ejbUrl = "sess_iiop://localhost:2481:ORCL/test/TESTER/ejb/bestdata.BestdataModule";
String username = "TESTER";
String password = "TESTER";
Hashtable environment = new Hashtable();
environment.put(javax.naming.Context.URL_PKG_PREFIXES, "oracle.aurora.jndi");
environment.put(Context.SECURITY_PRINCIPAL, username);
environment.put(Context.SECURITY_CREDENTIALS, password);
environment.put(Context.SECURITY_AUTHENTICATION, ServiceCtx.NON_SSL_LOGIN);
BestdataModuleHome homeInterface = null;
try {
Context ic = new InitialContext(environment);
homeInterface = (BestdataModuleHome)ic.lookup(ejbUrl);
catch (ActivationException e) {
System.out.println(e.getMessage());
e.printStackTrace();
System.exit(1);
catch (CommunicationException e) {
System.out.println(e.getMessage());
e.printStackTrace();
System.exit(1);
catch (NamingException e) {
System.out.println(e.getMessage());
e.printStackTrace();
System.exit(1);
try {
System.out.println("Creating a new EJB instance");
RemoteBestdataModule remoteInterface = homeInterface.create();
// Method calls go here!
// e.g.
// System.out.println(remoteInterface.foo());
catch (Exception e) {
System.out.println(e.getMessage());
e.printStackTrace();
It doesnt cause any errors. However, how must I call methods? The public interface RemoteBestdataModule has no such methods:
void doNothingNoArgs();
void doNothingOneArg(java.lang.String astr);
void setCertificate(java.lang.String userName, java.lang.String userPassword);
java.lang.String getPermission();
Instead of that it has the following methods:
oracle.jbo.common.remote.PiggybackReturn doNothingNoArgs(byte[] _pb) throws oracle.jbo.common.remote.ejb.RemoteJboException, java.rmi.RemoteException;
oracle.jbo.common.remote.PiggybackReturn doNothingOneArg(byte[] _pb, java.lang.String astr) throws oracle.jbo.common.remote.ejb.RemoteJboException, java.rmi.RemoteException;
oracle.jbo.common.remote.PiggybackReturn customQueryExec(byte[] _pb, java.lang.String aQuery) throws oracle.jbo.common.remote.ejb.RemoteJboException, java.rmi.RemoteException;
oracle.jbo.common.remote.PiggybackReturn setCertificate(byte[] _pb, java.lang.String userName, java.lang.String userPassword) throws oracle.jbo.common.remote.ejb.RemoteJboException, java.rmi.RemoteException;
oracle.jbo.common.remote.PiggybackReturn getPermission(byte[] _pb) throws oracle.jbo.common.remote.ejb.RemoteJboException, java.rmi.RemoteException;
I cannot call those methods. I can see how they are called in BestdataModuleEJBClient.java file:
public void doNothingNoArgs() throws oracle.jbo.JboException {
try {
oracle.jbo.common.remote.PiggybackReturn _pbRet = mRemoteAM.doNothingNoArgs(getPiggyback());
processPiggyback(_pbRet.mPiggyback);
if (_pbRet.isReturnStreamValid()) {
return;
catch (oracle.jbo.common.remote.ejb.RemoteJboException ex) {
processRemoteJboException(ex);
catch (java.rmi.RemoteException ex) {
processRemoteJboException(ex);
throw new oracle.jbo.JboException("Marshall error");
However, I cannot call getPiggyback() function! It is a protected method, it is available to the class BestdataModuleEJBClient which extends EJBApplicationModuleImpl, but it is unavailable to my class BestClients which extends Object and is intended to extend oracle.jdeveloper.html.WebBeanImpl!
It seems to me that I mustnt use RemoteBestdataModule interface directly. Instead of that I must use the public class BestdataModuleEJBClient that extends EJBApplicationModuleImpl and implements BestdataModule interface. It contains all methods required without additional arguments (see just above). However, how must I create an object of BestdataModuleEJBClient class? That is a puzzle. Besides my custom methods the class has only two methods:
protected bestdata.common.ejb.RemoteBestdataModule mRemoteAM;
/*This is the default constructor (do not remove)*/
public BestdataModuleEJBClient(RemoteApplicationModule remoteAM) {
super(remoteAM);
mRemoteAM = (bestdata.common.ejb.RemoteBestdataModule)remoteAM;
public bestdata.common.ejb.RemoteBestdataModule getRemoteBestdataModule() {
return mRemoteAM;
It looks like the remote application module must already exist! In despair I tried to put down something of the kind at the client side:
RemoteBestdataModule remoteInterface = homeInterface.create();
BestdataModuleEJBClient dm = new BestdataModuleEJBClient(remoteInterface);
dm.doNothingNoArgs();
Of course, it results in an error.
System Output: null
System Error: java.lang.NullPointerException

System Error: void bes
System Error: tclients.BestClients.main(java.lang.String[]) (BestClients.java:76)
I have studied a lot of documents in vain. I have found only various senseless discourses:
"Use the Application Module Wizard to make the Application Module remotable and export the method. This will generate an interface for HrAppmodule (HrAppmodule.java in the Common package) which contains the signature for the exported method promoteAllEmps(). Then, deploy the Application Module. Once the Application Module has been deployed, you can use the promoteAllEmps() method in your client-side programs. Calls to the promoteAllEmps() method in client-side programs will result in calls to the promote() method in the application tier."
However, I have failed to find a single line of code explaining how it should be called.
Can anybody help me?

Calling public class method from the servlet dopost() implementation

Hi!
My application is a simple application where i wrote a JSP page to enter the USERNAME and PASSWORD. And this JSP will call a HttpServlet
with in which i am calling another Java class ValidateUser which will check aginst the Oracle Database table whether that Username and password combination exists and returns the user's name.
But when i am trying to call that method is throwing me an error. here is the typical code i wrote.
servlet
package isispack;
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.*;
import java.io.*;
public class Login extends HttpServlet{
public void doPost(HttpServletRequest req, HttpServletResponse res)
               throws ServletException,IOException{
String userId = req.getParameter("user_id");
String password = req.getParameter("user_pass");
// if uName is null .. user is not authorized.
String uName = Validate(userId, password);
and
Validate class
package isispack;
import java.sql.*;
import java.util.*;
import java.lang.*;
public class ValidateUser
public String ValidateUser(String inputUserid, String inputPwd) throws
SQLException{
     String returnString = null;
     String dbUserid = "isis"; // our Database user id
     String dbPassword = "isisos" ; // our Database password
     Connection con = DriverManager.getConnection("jdbc:odbc:JdbcOdbcDriver","isis","osiris");
     Statement stmt = con.createStatement();
     String sql= "select user_id from isis_table where user_id = '" inputUserid + "' and user_pass= '" + inputPwd +"' ;" ;
     ResultSet rs = stmt.executeQuery(sql);
     if (rs.next())
     returnString = rs.getString("user_id");
     stmt.close();
     con.close();
     return returnString ;
The ERROR
Error(18,18): method ValidateUser(java.lang.String, java.lang.String) not found in class isispack.Login
One more thing i forgot to tell you. I am trying to run this application on JDeveloper. Please helpme out if you can . Thank you.
-Sreekanth

OK! I made it static method
and tried to call the method as follows
String uName = ValidateUser.ValidateUser(userId, password);
even if i create the instence and
ValidateUser Validate;
then call
String uName= Validate.ValidateUser(userId,password)
In either case is giving me the following error.Tarun, am new to Java programming, please help me out. And can you please tell me where can i find things in consise to brush up my fundamentals?.
Error(18,43): unreported exception: java.sql.SQLException; must be caught or declared to be thrown
