Problem XI 2.0 java.lang.ClassNotFoundException
We are trying to connect a DB2 system to XI via adapter. We get
java.lang.ClassNotFoundException: COM.ibm.db2.jdbc.net.DB2Driver
error when we try the restart.
CLASSPATH includes the .jar and .zip fies for the DB2 JDBC driver.
xidadm> echo $CLASSPATH
/usr/opt/db2_08_01/java/db2java.zip:/usr/opt/db2_08_01/java/db2jcc.jar:/

onal-lib/sapjco.jar:
We updated EXTLIBS and ADAPTERLIBS with the .jar and .zip locations.
What is missing ?
Hi Hart - Our Basis person made the change noted, but still getting the same problem. He also posted the problem in OSS. Adapter configuration are --

Done.
in my form i have created a bean_area and used as implementation class :ApiConn
in my formsweb.cfg i used this configuration: archive=frmall.jar,siberia_jpg.jar,ApiConn.jar,Hasher.jar,ReadCommand.jar,WriteCommand.jar,libAPI.jar
in my forms/java i have placed my jar files listed in the frmall.jar
i guess i am missing something but i dont know what it is.
here is my ApiConn.java from wich i generate my jar file:

My web page uses a Java Applet to allow my visitors to replay chess games; the Chess Viewer Deluxe applet was written by Nikolai Pilafov some time ago and has been working properly for some time (until recently). I don't monitor this part of my site regularly so I am not sure when it began to fail. On his web site [http://chesstuff.blogspot.com/2008/11/chess-viewer-deluxe.html] he has a link to check LiveConnect object functionality (which fails for OBJECT tags). His recommendation is to "seek platform specific support which might be available from the JRE developers for your platform".
I have been getting java.lang.ClassNotFoundException: ZeroApplet.class and java.lang.ClassNotFoundException: JavaToJS.class crashes with JRE version 1.6.0_26-b03-384-10M3425 VM executing a Java Applet. Until I checked the LiveConnect object functionality, I was unable to identify the source of the console error messages. This does seem to be the smoking gun.
Is Apple aware of this problem? Are these classes no longer supported? Has anyone else had this problem? You can attempt to recreate the problem locally by going to my web page: http://donsmallidge.com/DonSmallidgeChess.html
Thanks in advance for any help you can provide!

Migration problem from Struts 1.2.7 to 1.3.8:java.lang.ClassNotFoundExcepti
Hi, my current configuration is tomcat 6.0.18 and jdk 1.5. Here are the steps I followed for the migration.
1. Replaced struts.jar with struts-core-1.3.8.jar
2. Updated taglib .tld files which were under /WEB-INF and also kept the corresponding struts-taglib-1.3.8.jar files in lib directory.
3. Kept the external mappings in web.xml for the tld files though.
4. Updated struts-config.xml with
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.3//EN"
"http://struts.apache.org/dtds/struts-config_1_3.dtd">
5. As not using any cancel buttons hence did not use the cancellable attribute.
6. Updated validation.xml with specified doctype in strutsupgrade docs.
7. Replaced older jar files with newer versions.
After compiling the files and deploying in Tomcat I get the following error while trying to run.
exception

What am I missing out on?
Thankx in advance.hanks for the reply.
All class files are created during build.
I even deleted all the existing ones in tomcat/work folder.
So the classes are up to date.
Any other pointers?
Furthermore do I need to change the jsp header
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>
to
<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>
and so forth?(I did that, and its compiling but during accessing i get the same error.)
The java deprecations shows Resources.getLocale as deprecated. Is that a problem,
and if it is how to replace it? -
SetLookAndFeel and java.lang.ClassNotFoundException problem
Hi there, I'll admit I'm a newbie, but I really need help. I'm trying to create a GUI with a Metal layout: here the code:
public static void main(String[] argument) {
UIManager.setLookAndFeel
("javax.swing.plaf.metal.MetalLookAndFeel");
when I try to compile the file, it gives following error:
unreported exception java.lang.ClassNotFoundException; must be caught or declared to be thrown
UIManager.setLookAndFeel
("javax.swing.plaf.metal.MetalLookAndFeel");
^
please remember i'm a newbie, so go easy on the lingoimport javax.swing.*;
import java.awt.*;
public class MainFrame extends JFrame {
public MainFrame() {
super("Vloot Verslag 2006");
setSize(350, 100);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
Container pane = getContentPane();
FlowLayout flo = new FlowLayout();
pane.setLayout(flo);
JButton Accounting = new JButton("Accounting");
Accounting.setEnabled(false);
JButton Logistics = new JButton("Logistics");
JButton Exit = new JButton("Exit");
pane.add(Accounting);
pane.add(Logistics);
pane.add(Exit);
setContentPane(pane);
public static void main(String[] argument) {
UIManager.setLookAndFeel("javax.swing.plaf.metal.MetalLookAndFeel");
MainFrame sal = new MainFrame();
Ok there is my whole file, I just need to know what I am doing wrong -
MIDlet problem : java.lang.ClassNotFoundException
Hi, I'd like to write a simple java midlet so I'm looking at the examples on page http://developers.sun.com/techtopics/mobility/midp/articles/midpwap/ .
I have Java SDK 1.4.2.10 and J2ME Wireless Toolkit 1.0.4_02 installed on a Win2K pro PC.
Each time I run an example it compiles, then I get the message java.lang.ClassNotFoundException on the phone screen.
How can I get these examples to work?
THANKSyou must define midled class in .jad file or manifest file

Windows Vista "java.lang.ClassNotFoundException: loader.class" error.
Hello,
Whenever I try to visit websites that have a java applet I get a dialogue with the following error:
java.lang.ClassNotFoundException: loader.class.
I have tried uninstalling/reinstalling java, and also adding the -xmx and -xms parameters for java applet runtime setting in control panel with various values from 128m to 1g.
The applet at http://www.java.com/en/download/installed.jsp?detect=jre&try=1 does work and reports "CONGRATULATIONS, you have the Latest version of Java!", "Java Runtime Version 1.6.0."
I have been experiencing this problem ever since I installed Windows Vista Home Premium a day or two ago. Any help is appreciated.
Regards
Greg

Thanks & Regards,
KavithaHi James, Yes i do know that the class is not found during run time. The actual place where i need to use this function module is a different DC. But as i face this problem, for testing purpose i tried using it in the same DC where the model exists. I get the exception there too.
It occurs exactly in the line where i bind the function module in my init method.
Line 191 in my init method is this,
// bind the "get document" FM
Z_Hjm0033_Get_Merged_Document_Input document = new Z_Hjm0033_Get_Merged_Document_Input();
wdContext.nodeZ_Hjm0033_Get_Merged_Document_Input().bind(document);
For your information, the class not found Zhjm0001_Document_Id is a data element to which one of the function module's (Z_Hjm0033_Get_Merged_Document) import parameter is associated with.
I could not locate the constructor which you are asking for. I searched in gen_ddic and gen_wdp. Can you help?
Thanks,
Kavitha

Java.lang.ClassNotFoundException error when running a form
Hello,
On a Windows 2003 64 bits server I have installed Oracle Application Server 10gR2 10.1.2.0.2 (Infrastructure + Business Intelligence and Forms option). I also upgraded to Portal 10.1.4. All components are up and running.
I wanted to test if Forms services are functional using the test form provided by OAS at installation (test.fmb/.fmx).
Steps executed:
1) Start -> Programs ->Oracle Application Server 10g -> Forms Services -> Run a form on the web for form=test.fmx
or in the IE browser:
2) http://pwr-hp-srv.replynet.prv:7778/forms/frmservlet?form=test.fmx
The applet is not starting and I receive the following error:
java.lang.ClassNotFoundException: oracle.forms.engine.Main
What does this mean? What should I do to make it work?
Any help will be appreciated.
Tahnk you.
danielaHello again,
I solved the problem.
In Control Panel -> JInitiator administration console , the option "Use browser settings" has to be unchecked.

Java.lang.ClassNotFoundException: MyApplet
Hi everybody!
I have a problem with loading my applet on the other machines than mine. On my computer everything seems to be fine and my applet works perfectly, but when I try to run it on the other computers, I always get the following error:
java.lang.ClassNotFoundException: MyApplet
Just to mention, my class files are in the same directory as html file, the case is correct and all the images I use are also there. The html code is following:
<applet code="MyApplet.class" width=200 height=170>
</applet>
I cannot think of anything else I could try.
Thanks in advance!If MyApplet is in a package, then that could explain why you get that error. If e.g. the full class name is mypackage.MyApplet, then you have to move MyApplet into a folder mypackage that is in the folder with the html file. And the code tag should be mypackage.MyApplet.
If MyApplet is inside a jar file, then you will have to include it in a codebase attribute.
I don't know what else could give you that error. -
"java.lang.ClassNotFoundException" when creating a CFC instance inside a webservice
This question is also up on stack overflow: http://stackoverflow.com/questions/10089962/coldfusion-web-service-failing-to-see-componen t
I've got a CFC that I'm going to access with ?wsdl as a SOAP webservice.
If I call the CFC directly in a browser, my results render fine:
http://server/webservice/calc.cfc?method=doStuff&foo=bar
If I try to access it as a web service:
ws = CreateObject("webservice", 'http://server/webservice/calc.cfc?wsdl');
result = ws.doStuff('bar');
I get an error:
Cannot perform web service invocation doStuff.
The fault returned when invoking the web service operation is:
AxisFault
faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException
faultSubcode:
faultString: coldfusion.xml.rpc.CFCInvocationException:
[coldfusion.xml.rpc.CFCInvocationException : [java.lang.ClassNotFoundException :

at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)
at sun.r... ''
The problem is because the doStuff function is declaring an instance of a CFC inside it:
remote struct function doStuff(foo) {
var objReturn = {};
objReturn.msg = 'A message';
// do a calculation
var objCalc = new com.calculations.calc(foo);
objReturn.calc = objCalc;
return objReturn;
So my CFC that I'm using as a webservice has got another CFC being declared inside a function. Browsing directly to my webservice CFC works fine, but trying to call it using the CreateObject/webservice route fails, as it can't create an instance of the **com.calculations.calc** component.
It doesn't error, wierdly, if I comment out the objReturn.calc = objCalc line. So it seems I can create the instance, but the error isn't thrown till I assign it to my return struct.
Also I've found, If I refresh the page a few times, sometimes the error changes to:
AxisFault

Message was edited by: PeteComcar - impvoed code formatting and added returntype updateDear All Technology Expert's,
I have a query related to Coldfusion SOAP services, that is most commonly asked in all the forum's but NONE of them has got answer.
If there is NO solution so I think Adobe has to come up with some patches so developer can able to do some customization.
I like to share with you all, in all other language ( PHP, JAVA, .NET etc) this option is available and you can customize the error.
Ok let me again explain the very basic error:
SOAP Request:
<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header/>
<soapenv:Body>
</soapenv:Body>
</soapenv:Envelope>
SOAP Response:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<soapenv:Fault>
<faultcode>soapenv:Server.userException</faultcode>
<faultstring>java.lang.Exception: Body not found.</faultstring>
<detail>
<ns1:stackTrace xmlns:ns1="http://xml.apache.org/axis/">java.lang.Exception: Body not found.
at org.apache.axis.providers.java.RPCProvider.processMessage(RPCProvider.java:121)...</ns1:s tackTrace>
<ns2:hostname xmlns:ns2="http://xml.apache.org/axis/">Coldfusion Error</ns2:hostname>
</detail>
</soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>
HOW we can customize the error, in all other languages you can simple customize the error like
Other languages SOAP response:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<soapenv:Fault>
<faultcode>BODY_NOT_FOUND</faultcode>
<faultstring>Body is missing in your request</faultstring>
</soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>
But the same is NOT possible in Coldfusion, right?
AS you know it is vulnerability to display exception messages in the response.
We are developing this web service to access from other language website (PHP, .NET).
We are also planning to upgrade server the Coldfusion 11, but do you think there is any solution with latest Coldfusion version.
Please response only if you know about these issue's or solution.
Thanks

Exec] error: RmiModeler error: java.lang.ClassNotFoundException: webservice
hi,
Im trying to build a very basic web service using jaxrpc and i get the following errors
error 1
[exec] error: RmiModeler error: java.lang.ClassNotFoundException: webservice$hostel$Hostel
[exec] Result: 1
all the server side Hostel code compiled when i complied it seperatly....done know why it is feakin out nowand givin errors.. can any help
error 2
[exec] error: XML reader error: java.io.EOFException: Unexpected end of ZLIB input stream
haven't a clue what this is!!!!I am having a similar problem with RmiModeler errors:
http://forum.java.sun.com/thread.jsp?forum=331&thread=498925&tstart=0&trange=15
I am using asant and it is building fine, but the wscompile is falling over -
Unmarshalling return; nested exception is: java.lang.ClassNotFoundException
I think what I'm trying to achieve is probably very simple (or at least should be) but I've been trying for at least 5 hrs now:
I'm using RMI for a distributed app I'm building for my degree.
Up until today I got around the need for using a SecurityManager by including all shared classes (those I pass between client and server) in a class library .jar file referenced by both client and server projects.
This has worked fine, but now I've coded a method that returns an object of a class that I do NOT want to include in the shared library (because I don't want the client to be able to construct these objects); therefore, I've decided to try and get the dynamic class loading working.
I'm using netbeans and testing on a single computer.
Here's what I'm trying:
My main() method has the standard code I've seen: if (System.getSecurityManager() == null) System.setSecurityManager(new RMISecurityManager());
In the server project's Run properties, I'm specifying VM Options: -Djava.security.policy=c:\security.policy -Djava.rmi.server.codebase="file://C:/"
I've copied the ellusive class's .java file into C:\ to keep the URL simple, but I've also tried directing it to the netbean project's bin\ folder using '%20' for spaces, both with the same results - about a five second pause (so it's finding something I think) and then the error message from the client's output:
error unmarshalling return; nested exception is: java.lang.ClassNotFoundException: mypackage.myClass
My policy file's contents are:
grant {
permission java.security.AllPermission;
I've tried about 20 different ways of formatting the codebase argument's URL.. can anyone help?
David
p.s. my OS is Windows 7Thanks EJP,
Yes, after posting I guessed it might want the .class file instead, so I directed it their instead - still no joy, unfortunately!
I'm carrying out all testing on one computer, so (+if+ I could get it to work) a local codebase address would not be a problem.
Noted about the server-side security manager. I might want to use callbacks, but the server still won't need to download class files from the client, so I'll still try and set the codebase, but will try without loading a security manager on the server-side.
For the time being I've put the class in the shared library but have defined it within the same package as the server code. By doing this I've been able to set the class's accessibility back to default, but the client can still access it as Object (from the shared library).
This solution is good enough, but I still wonder why the client refuses to accept the class file from the C:\ codebase. -
Help:java.lang.ClassNotFoundException
we have one application.We are calling ejb through applet.
We have sybase EAServer3.6.1 and jaguar 3.6.1.Java code is in jdk118 and ejb1.0.
Our architacture is: applet<->ejb<->server.
Our ejb is deployed on server.That we are calling our ejb through applet.Whole code for applet and ejb is lying on server.When we run our application through browser from different m/c we are getting two errors.
1)com.ms.security.SecurityExceptionEx.
2)powersoft.powerj.jaguar.InitialContextException: javax.naming lookup failed for component: HelloEJBPackage/HelloEJB
Exception: [Root exception is [Root exception is java.lang.ClassNotFoundException: java.rmi.Remote]javax.naming.NamingException]javax.naming.NamingException.
When I set classpath on each m/c.
i.e (c:/prog/sybase/shard/sun/jdk118/lib/classes.zip) my application is running fine it just gives warning for securiety not for lookup method failed.
Our system is in production.We can not make setting for individual clients.We need our applet should take classes from server not from client m/c.
Can anybody help me to solve this problem?If the client is created using powerj, pl cross verify the code for the lookup() in the client with component properties in the jaguar server.
check the component properties , in the installed packages of the jaguarCTS , under jaguar manager of the sybase central java edition.
