Why "Interface SQLData of class not found"?

Could anyone please help me?
I use JDK1.2.2 with Oracle 8.1.5.
I wanna try the example of SQLData Implementation here: http://technet.oracle.com/doc/oracle8i_816/java.816/a81354/samapp6.htm#1016717
But I just got the error message keeping saying that "Interface SQLData od class EmployeeObj() not found".
What's up with it?
Any response is appreciated. :)

Hello Carlos
It is possible that something went wrong when you imported the class into your TEST system.
The error message could imply that the corresponding record is missing from table TRDIR.
I would recommend to make a small change of the class in your DEV system (e.g. change description) and transport the entire class gain into the TEST system (context menu within SE80 -> create Transport Entry for entire class).
After the import you should go to SE24 and activate the class to see if everything is ok.

Class Not Found in Server Application

I have set up a basic server application. It contains three files namely
Arith.java (implements the Remote interface)
ArithImpl.java (implements Arith.java the server) and
ArithApp.java which is the client Application
All of these are in the same package. I have compiled all of these files and I execute the rmic ArithImpl command from within the ArithImpl.java file via Runtime.getRuntime.exec(...);
The stub and skeleton files are generated and still I get a class not found exception. I have checked the class path and these files are within the class path.
If anyone could help me I'd greatly appreciate it. Thanks

Service Bus 12c Class not found 'oracle.tip.pc.services.functions.ExtFunc'

Hi,
Did anyone came across this issue with Class not being found for XSLT Function used in transformer on 12c OSB.
I'm using oraext:sequence-next-val and have configured as below:
namespace-uri:http://www.oracle.com/XSL/Transform/java/oracle.tip.pc.services.functions.ExtFunc
namespace-prefix: oraext
Not sure why at runtime I'm getting below error, as the same was working fine in 11g OSB Domain.
XML-22045: (Error) Extension function error: Class not found 'oracle.tip.pc.services.functions.ExtFunc'

Have you restarted servers after putting jar in $Domain_Home/lib directory? Also try after explicitly adding this jar in classpath by editing server startup script (startManagedWeblogic.cmd or .sh) or in domain env setting script (setDonainEnv.cmd or .sh) and restarting the servers.
Regards,
Anuj

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 String[] getNames() throws RemoteException{

public static void main(String args[]) {

// 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().

Class not found error afer loading classes to oracle

hi i have loaded quite a few jars into oralce 11g databse
created a java stored function
and executed it
some times it works... and hits the java front end environment... we are hitting a servlet.. and recording some output statements .. in the function
but sometimes it throws class not found error
any idea why its working sometimes and not some othr times?
Also when i load the jars.. the classes are loaded but when i see the name of the classes using
select * from user_objects where object_type like 'J%'
then i see some additional characters prefixxed the class names ... is that causing the problem?
something like this

Learning_man,
Obviously you need to learn how to ask a question.
There is nothing in your post other than 'It doesn't work. Why? Help"
without any specific example. Also you still fail to include a 4 digit version!!!
It is also the third or the fourth time you asked this very same question.
Can you learn how to ask a question please? And stop repeating the question when you don't get a response?
And no, the extra characters are not the problem.
An incorrect CLASSPATH probably is.

Class not found error for applet.

This is probally a really simple mistake but I've tried everything and can't find it.
My applet works fine with applet viewer - I'm running it from JBuilder. But when I open my html file in the browser it gives me a 'Class not found' error. I've tried running other applets (my own and demos on this site) and they work fine.This is the applet tag code:
<applet code = "Rotary.class" width = "650" height = "580" align = "top">

<param name = "sector0" value ="234,215,244,207,154,43,125,63">
</applet>
The class file is in the same directory as the HTML file. Do I need to specify the codebase? I tried that too - giving it the full pathname of the class.
In the Java console it said that it couldn't find "C:Project\Rotary\javax\swing\japplet"
I don't think it could have anything to do with the fact that I'm using swing because the other applets I used used swing.
Please help - I'm really running out of ideas here!

You have a similar problem like I had.
You seem to have a too old JAVA environment for the browser - I had a too new environment.
For all who are experiencing the same problem!
Problem:
You're compiling your applets with a quiet modern compiler (i.e. Netbeans Version 3.5.1)
You are able to compile your applets without any problems but if you try your applets in "real life", the browsers can't interpret your applets [class not found]. (I tested Internet Explorer 6.0 and Netscape Navigator 4.7)
So you need a plugin for the new JAVA environment because the JAVA environment of the browser is older than that which the applet needs.
Well, you have the choice to demand to every user of your applet to download the new Java Runtime Environment, but then don't wonder why nobody visits your site!
But, don't worry: I figuered out another solution, that Netbeans (www.netbeans.org) allows to compile in different JAVA versions.
Solution:
What you have to do is:
- Install a previous version of JDK (i.e. JDK 1.3 - I would suggest, lower versions don't work with Netbeans 3.5.1 and JDK 1.3 is enough for IE 6.0 and NN 4.7, which I tested)
- Go into the "bin"-directory of Netbeans (i.e. c:/netbeans3.5.1/bin)
- Open the file "ide.cfg" (with notepad or any other texteditor)
- You see a line like: jdkhome "C:\java\j2sdk1.4.2" -J-Xmx96m -J-Xss1024k -J-Xms24m -J-Xverify:none
- Change the path to your other JDK you wish, like: jdkhome "C:\java\jdk1.3" -J-Xmx96m -J-Xss1024k -J-Xms24m -J-Xverify:none
- That's it, you can compile your applets in a previous version of JAVA so that "older" browser user don't have to install a plugin for the new JAVA environment.
Have fun!
If you have any questions I would be pleased to help you.
If this tip helped you already I would be pleased if you would send me a quick email with your experience.

Class Not Found Error Doesn't Make Sense

Possible answer to CNF Exception problems.
I have written a simple slide show applet that displays a sequence of jpgs. In order to make it work for the majority of people and older systems I used the AWT Applet rather than the JApplet framework.
I compiled it using the latest JDK 1.4.1, ran it using applet viewer and locally inside my web browser (IE 6.0) and it all worked fine.
I uploaded it to a web-server, tested it and received a Class Not Found exception. After a few hours of checking, rechecking (code= codebase= etc. etc.) I decided to use an older version of the JDK to compile the applet (since the code was compatible). The oldest I could find was 1.1.8, so I compiled, uploaded and it works on every computer I've tried???
What is the problem here?? Windows 98, the 1.4.1 JDK, IE 6.0?? Has anyone had similar problems before? Why did it work locally but not online?

Hi.
Instead of using the old JDK you can also compile your code for a specific version with
javac -target 1.1 MyApp.javaCheers,

Class not found in web-inf/classes folder of war file within ear file

Hi all,
          I am using Weblogic 8.1 sp4. I have a war file within an ear file. I am trying to deploy the war file with a few classes within its web-inf/classes folder, however when the classes are in that folder I consistently get a class not found exception when trying to instantiate them. If I package the classes in a jar file and then put that jar file within the web-inf/lib folder of the war, the classes are also not found.
          If I put these two classes in the app-inf/classes folder of the ear file, everything works as expected and the classes are found.
          Any ideas of why this is happening. This seems to be a very simple thing that should work, but appears to not be working at all.
          thanks in advance for any suggestions or ideas.

Hi,
          This is a known limitation/issue with WL. There is also no way around this.

Class not found error for COM.ibm.db2.jdbc.app.DB2Driver

i have written this code:
import java.io.*;
import java.sql.*;
public class tryjdbc
{ public static void main (String args[])
{ try
{ Class.forName("COM.ibm.db2.jdbc.app.DB2Driver"); }
catch (java.lang.ClassNotFoundException e)
{ System.out.print(e.getMessage()); }
and once i try to run it, it gives out a class not found exception error.
I haven't changed anything with the classpath since I don't think the problem is with the classpath. I have read in the IBM Developer Kit for Java documentaton that the AS/400 Developer Kit for Java automatically adds the db2_class.jar file to the classpath. So why do I get a class not found exception error?

I was using Web Spehere 4.0.3 and trying to connect to a database on DB2 7.2. I was just following a tutorial and trying to get a handle on Web Sphere. I am running all of these on a Windows 2000 Operating System. Here are some of my observations :
a. db2java.zip packaged under %DB2ROOT%\SQLLIB\JAVA, does not work.
b. CLASSPATH needs to be set to %DB2ROOT%\sqllib\java12\db2java.zip
c. Include this as one of the packages in the package defined in
WebSphere, using the Java Perspective.
d. Ensure that case sensitivity is respected. All though the package
shows up as COM.ibm.db2.jdbc.app.DB2Driver, for some reason, it
will only accept com.ibm.db2.jdbc.app.DB2Driver.
With these settings, I was able to connect to a db2 database.
I am a little puzzled on the following. I did not include java.io package, but still it could print the messages. Did anybody have a similar experience
Thanks for this posting.

Java.rmi.UnmarshalException: skeleton class not found but required for clie

Hello everyone,
I am new to RMI and getting a strange exception. I am using Java 1.5.0_07 both on client and server. They are running on the same machine, the rmi registry is started inside the server application.
I am wondering why java complains about skeletons, I thought they are automatically created when using java 5.0?
Please have a look at the stacktrace below.
Thank you for your help.

Compilation Error for import classes not found in generated Proxy Class

Hi,
We are generating java classes for the COM dll using JCOM com2java compiler.
We are getting a compilation error for import class not found when compiling the
generated Proxy java source code. It can't find the com.bea.jcom.Dispatch class that
the generated Proxy java source code extends. It also can't find com.bea.jcom.Variant
or com.bea.jcom.Param. These are interfaces or data types or classes used by COM
library.
I added weblogic.jar to my class path and the only Dispatch class i found inside
the weblogic.jar is com.linar.jintegra.Dispatch;
We have com objects for which we want to develop an EJB client to interface with
the COM object using JCOM with Native Mode disabled.
Any help on the compilation error..I tried changing the extends for Dispatch to com.linar.jintegra.Dispatch
but the other errors are still there.
To begin with, I think the generated code should not refer to any of the COM data
types.
Any help please.
Thank you in advance,
Regards,
Rahul Srivastava

Hi,
I resolved the other errors by changing all references from com.bea.jcom.Variant
etc to com.linar.jintegra.class name..all were present under the com.linar.jintegra
package.
Thank you all anyways,
Regards,

Class not Found Exception while running an EJB

I have created and published a EJB in Oracle 8i (in a particular

Struts class not found for war file

Hello,
I am tring to deploy my struts web application in weblogic 8.1. I have all the
library files in web-inf\lib directory. It gave me the error that class not found
for some class in struts library. The console also told me the classpath. But
I can use javap to find the class using the same classpath. Could any one point
me some direction what I am doing wrong here.
Thanks.

Hello Mark,
Your suggested solution (putting an empty commons-logging.properties into
web-inf/classes or in a jar in web-inf/lib)
does not make any change at all. It still complains about not being able to
preload the servlet and still
gives exceptions upong calling upon LogFactory.
What I have been able to do is put the three classes from
com.bea.wlw.netui.util.logging into a separate jar
and add that to web-inf/lib.
However I am sometimes getting funny exceptions upon undeploy
(NoClassDefFoundError for org.apache.commons.collection.FastHashMap$KeySet).
Regards,
Robert Varga

From a FAQ on netui:
1. Why do I get a ServletException while trying to deploy a struts web
application on a Workshop/Integration/Portal domain?
In the "<WL-HOME>/server/lib/knex.jar" file there is a properties file
called "commons-logging.properties" which configures the
com.bea.wlw.netui.util.logging.StrutsLogFactory class for Struts loggingas
below:
org.apache.commons.logging.LogFactory=com.bea.wlw.netui.util.logging.StrutsL
ogFactory
This class file is not available for a Struts web application that was not
built using Workshop, the reason being the containing NetUI jar files are
not present in the web application's WEB-INF/lib folder. This leads to a
ServletException while deploying the web application. The solution is toadd
a blank file (or a JAR containing the file) namedcommons-logging.properties
to the server CLASSPATH, or to the WEB-INF/lib folder of the concerned web
application. This issue will be fixed in Service Pack 2.
cheers

Hi Rob,
I also have a similar error with deploying a Struts web application into
a
8.1 Basic Workshop Domain created
by 8.1 Platform.
I get a ClassNotFoundException for 'com.wlw...StrutsLogFactory', whenStruts
tries to load any Jakarta class
from commons-beanutils or Struts which has logging.
This happens because commons-logging picks up some property whichinstructs
it to load that class, which is
naturally not included in most web applications, since it is
workshop-specific. This property definition, I think,
is in <bea>\weblogic81\server\knex.jar, called
commons-logging.properties,
containing the following line:
org.apache.commons.logging.LogFactory=com.bea.wlw.netui.util.logging.StrutsL
ogFactory
How can I override this in my webapp in a property file, so that when a
Struts or Beanutils class calls
LogFactory.getLog(org.apache.....<classname>.class), it would not try touse
the property file and the
class defined in knex.jar.
Thanks in advance,
Robert Varga

Actually it complained about a NoClassDefFoundError. Generally this
is
caused by something in a parent classloader that is found but then
depends on something only loadable in a child classloader.
eg.
You have something in your $CLASSPATH that references something in the
WEB-INF/lib. This will NoClassDefFoundError.
So, as I recommended, remove everything you've added to the$CLASSPATH,
add the jars to WEB-INF/lib. If you're still having problems, show me
your $CLASSPATH, the contents of WEB-INF/lib, and the error message
/stack trace.

Hello, Rob,
I did put the common-beanutils and other jar files in the
web-inf/lib
directory.
And from the weblogic console, I do see the jar file get included in
the
classpath.
(those generated file name have some number attached at the end.)
As
I
mentioned
before, I can use javap find the class using this weblogic generatedclasspath.
But weblogic complained that the class is not found.

JNLPClassloader raises class not found Exception

I have some class files which are part of a jar file. I made sure this jar is downloaded by JWS on client machine. When application is launched in stand alone mode then JNLPClassloader complains at runTime that particular class is missing.Although this class is already inside jar file.
Did any one faced similar situation when JNLPClassloader raises "Class Not found Exception" ? How this can be avoided?

yeah i made sure classes are put in proper folder. As i am using Eclipse,JDK1.6, jboss so when i launch application directly from Eclipse then it works fine.
But if i launch through JWS then it does not work. I am not able to understand why JWS can not detect classes inside Jar file downloaded on client machine ?

Class not found: org.springframework.beans.factory.BeanCreationException

I am deploying an .ear file to an Oracle Application Server 10.1.2.0.2. In one container, it deploys correctly. In another conatiner on the same server and configured identically (or at least I believe), I try to deploy the same .ear file but I get the error:
Deployment failed: Nested exception
Resolution:
Base Exception:
com.evermind.server.rmi.OrionRemoteException
Class not found: org.springframework.beans.factory.BeanCreationException; nested exception is:
java.lang.ClassNotFoundException: org.springframework.beans.factory.BeanCreationException. Class not found: org.springframework.beans.factory.BeanCreationException; nested exception is:
java.lang.ClassNotFoundException: org.springframework.beans.factory.BeanCreationException
Anyone would have an idea why? Thanks in advance.

Greetings,
Your error implies that the classpath for the second deployment might be wrong. This cannot be the package if you are deploying an identical ear file. Can you look at the setup for the second container from the admin to see if there is an RMI connection configured incorrectly? Check your opmn.xml file for port info:
<port id="rmi" range="12401-12500"/>and check the server using netstat -a to see if the configured port is open for use before starting the OAS.

Why "Interface SQLData of class not found"?
