B2B Java Callout Class not found exception

Hello B2B Gurus,
I am facing class not found exception, when trying to call a java code from B2B and below the configuration done from B2B side.
Could you please help me to identify that the configuration done suffice the requirement
1.Created a call out from
Adminstration-- Callout-- Create Callout -- XXJavaCallout(Name of the Java Callout)
Administration-- Callout Details -- Implementation Class -- XXClassFileName
Administration-- Callout Details -- Library Name -- XXJarFileName.jar
Administration-- Configuration -- Callout Directory -- xx/yy/zz (UNIX server that is accesible from B2B)
2.Partners--XX--Delivery Channel -- Select the channel where we need the call out -- Channel Attributes -- Transport Callout -- XXJavaCallout
3.Agreement--Callout -- XXJavaCallout
Place the jar file in xx/yy/zz UNIX location.
Please let me know if any steps I have missed for using the callout functionality.
Thanks,
Sunil

Sunil,
Administration-- Callout Details -- Implementation Class -- XXClassFileNameMake sure that you are giving complete name of the class (without extension .class.). For an example if your class name is Sample and it is in package a.b.c then give class name as a.b.c.Sample
Administration-- Configuration -- Callout Directory -- xx/yy/zz (UNIX server that is accesible from B2B)This must be valid directory existing on machine where B2B is installed.
2.Partners--XX--Delivery Channel -- Select the channel where we need the call out -- Channel Attributes -- Transport Callout -- XXJavaCallout
3.Agreement--Callout -- XXJavaCalloutTransport Callout and Agreement Callouts are used for different purpose. Are you sure that you really need both in your case?
You may like to refer -

Java applet class not found exception for check scan

I am getting a class not found exception when trying to scan a check into a banking website. The application uses Java and the exception error has the name "com.epaysol.checkscanAppletV2" in the message. I have the latest Firefox and the latest Java installed. I tried going to an earlier version of Firefox and of Java where this app worked in the past and it does not work now in the earlier versions either. So I am now back to the latest version of everything.

No, the "-g" version just means it has the debug flag turned on when they compile it.
Your problem is CLASSPATH and how to set it properly.
Use the -classpath option on java.exe when you run. Read the javadocs on the tools to find out how.

Class Not found Exception for invoking BPEL process through the Java code

Hi.
The JDeveloper IDE raise the Exception From the invoking the BPEL process through the java code .Class Not Found Exception (Locator,ID.......).What is process of importing these classes from API.

In your code (.bpel file) import the library using the bpelx:exec tag. For example the adding the following entry in your .bpel file imports the com.oracle.bpel.client.util library.
<bpelx:exec import="com.oracle.bpel.client.util.*"/>

Not able to start the remote server - class not found exception

All,
I am quite new to RMI programming, although i am an experienced java programmer. I am facing a problem in starting the remote server program which i wrote for RMI. I am getting class not found exception for "stub" class eventhough the class is in the classpath.

Following are my classes:
MyRemoteInterface.java
import java.rmi.Remote;
import java.rmi.RemoteException;
public interface MyRemoteInterface extends Remote {
public String[] getNames() throws RemoteException;
public class MyServerImplementation extends UnicastRemoteObject implements
MyRemoteInterface {
public MyServerImplementation()throws RemoteException{
super();
public String[] getNames() throws RemoteException{
return new String[]{"Name1","Name2","Name3","Name4"};
public static void main(String args[]) {
try {
// Create an object of the HelloWorldServer class.
MyRemoteInterface obj = new MyServerImplementation();
// Bind this object instance to the name "HelloServer".
Naming.rebind("rmi://localhost:1985/GetNames", obj);
System.out.println("GetNames bound in registry");
catch (Exception e) {
System.out.println("GetNames error: " + e.getMessage());
e.printStackTrace();
public class MyRMIClient {
*@param args*
public static void main(String[] args) {
try {
MyRemoteInterface remObj = (MyRemoteInterface) Naming.lookup("rmi://localhost:1985/GetNames");
System.out.println("Names are "+remObj.getNames());
catch(Exception e) {
System.out.println("Problem encountered accessing remote object "+e);
}

That's a remote exception coming from the registry. You need to learn to recognize remote exceptions and their source, it's a mjaor source of confusion in RMI.
In this case it's the registry that can't find the stub class.
The stub class needs to be in the CLASSPATH of (i) the Registry and (ii) the client as well. Ditto the remote interface; ditto any application classes it refers to, and so on until closure.
The easiest way to achieve (i) is to start it in the server's JVM, with LocateRegistry.createRegistry().

Hi Mark,
I have seen your two posts and there are something you need to notice:
Where the ClassNotFound exception you got? From deployment tool or
application server kjs process?
Of course, you need not to add supporting classes to each ejb jars or ears.
1. If you use deployment tool to package your application, I'm sure you'll
fail to resovle your classes without supporting classes added to jars.
Please select Edit->Preference,in Classpath entry, enter the supporting
classes(packaged to jar files) location. This should work.
2. After deploy to ias, please edit the registry using kregedit which you
described in your posts.
Regards,
Johnson

news:9s6h33$[email protected]..
When I deploy EJBs to the iPlanet app server I find that I need to include
all supporting classes in each ejb jar file. According to the
Administrator's manual I should be able to modify the kjs classpath bydoing
the following:
On Windows
a.. Open iPlanet Registry Editor.
(See About iPlanet Registry Editor)
b.. Open the following key:
SOFTWARE\iPlanet\Application Server\6.0\Java\
c.. Modify the class path and restart the server for the change to take
effect.
However, when I add my supporting classes to a jar in this directory Istill
get a class not found exception when I run the deployment tool.
Adding the classes to each EJB jar is redundant and introduces lots of
problems. How should I configure iPlanet so I only need to put my
supporting classes in one place?
Thanks,
Mark

Error : class not found exception : com.mysql.jdbc.driver in Eclipse Tool

Hi
I have impoted project file in eclipse in new machine using option import from existing workbence . When i stat to debug this project ,
i am getting error as class not found exception : com.mysql.jdbc.driver . my project folder already consist of mysql .jar file in /web appls/web-inf folder.
Application is running successfully in other machine from where i took the application file. As this error appeared I also added jar file into project path as Project ---->properties-- build java path---libraries----add external jar file.
kindly hep me.

Sounds like an eclipse question - not a JDBC one.
But since eclipse is telling you it can't find it then it means it is not in the eclipse path. So you must add it. (The fact that it is somewhere is irrelevant - all that matters is it is not in the class path.)

RMI stub class not found exception

Configuration:
OC4J Release 2
Windows 2000
* I get a stub class not found exception when the RMI server is instantiated.
* I compiled the implementation class using rmic and created a jar file containing the stub and skeleton classes. The jar file has been included in both the WEB-INF/lib and the <OC4J-home>/j2ee/home/lib directories.
* "TestServer" class (given below) is instantiated in a servlet init() method (the exception is thrown here).
* Following are file listings (with code):
Remote Interface ---> Test.java
Implementation class ---> TestImpl.java
TestServer.java
Test obj = new TestImpl();
Context ctx = new InitialContext();
ctx.rebind("TestService", obj);
Any help is appreciated.

Found the solution. Thanx.

Java.lang.class not found

Hi,
I configured scenario FILE TO JDBC, the sender channel is successful but in the receiving I am getting the error that java.lang.class not found.
In the receiver communication channel, I gave "com.microsoft.jdbc.sqlserverdriver".
what database connection parameters need to be given??
Thanks,
Satish.

Whats your database ?
As Suresh said, did you deploy your JDBC driver ?
How to ?
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/xi/xi-how-to-guides/how to install and configure external drivers for jdbc and jms adapters.pdf
After configuring your communication channel, did you check the Adapter Monitor
XI SP > 09
http://<host>:5<sysnum>00/rwb -> Component Monitoring -> All Display -> Adapter Engine -> Adapter Monitor
XI SP <= 09
http://<host>:5<sysnum>00/AdapterFramework
Oracle Driver & Connection:
JDBC Driver: oracle.jdbc.driver.OracleDriver
Connection: jdbc:oracle:thin:@<hostname>:<port_umber>:<database_name>
SQL Server Driver & Connection:
JDBC Driver = com.microsoft.jdbc.sqlserver.SQLServerDriver
Connection = jdbc:microsoft:sqlserver://hostname:1433;DatabaseName=<DBName>

Class Not Found Exception After Connecting From a JDeveloper

Hi,
I am following the tutorial on SOA and started to experience problems in deployments (all but the console, including em) after the connection to the remote weblogic (10.3.5) from JDeveloper. I would know if the connection modifies the WLS environment. Unfortunately I did not note the message before wiping the setup, but found many entries on Google referring to some ADF library. I followed the suggestion to apply the adf runtime to the WLS install but this not helped.
By the way, I would just understand if the remote connection from a JDeveloper adds some configuration which is then eventually not found in the target WLS.
Thanks

Can you check the log files of soa_server1, which are located in the <domain-home>/servers/<server-name>/logs.
There are probably some occurences of class not found exceptions.
When you are using the node manager to start your environment you have to make sure that StartScriptEnabled is set
to true in the nodemanager.properties file (located in the directory: <wl-home>/common/nodemanager
In the section "Starting the SOA environment" here - http://middlewaremagic.com/weblogic/?p=6040
an example is presented

Class not found exception for the startup class defined.

iam using weblogic server 10 and bea jrockit 1.5.0.12.
i have created a startup class in the admin console for a web project and i have deployed the war file using the console in a user defined domains, user project directory.
when i start the server, iam getting class not found exception for the startup class.
But, the startup class is available in the web archive (war). how should we add the classes and jars in the war to the classpath in setDomainEnv.sh or is there any other setting available in the console to enable this.

Hello Julius,
yes sure, we can move this post to the NW admin forum. I have already posted similar thread on sun forums. I was hoping that someone from SAP SDN already tackled this problem and if not someone specialized in J2EE Engine could troubleshoot me from the class problem I'm getting. I don't know if it's specific from the agent or if this ClassNotFound is a general SAP J2EE Engine error relating to a library not correclty defined.
Kind regards,
Tanguy Mezzano
