Simple but wierd java.lang.NoClassDefFoundError with jar file

I'm using ant to jar my .class files. My final objective is to create an executable jar. When I run my jar file - "java -jar PM.jar" - I get:
Exception in thread "main" java.lang.NoClassDefFoundError: pm/PMApp
This at least tells me that java found my MANIFEST.MF class and that is the correct class it should be looking for, but it doesn't seem to find the class. But when I do - "jar -tf PM.jar" - I get:
C:\mike\pm\execs>jar -tf PM.jar
META-INF/
META-INF/MANIFEST.MF
pm/
pm/EasterEgg.class
pm/JMSMessageListener.class
pm/PMApp.class
pm/ReleasePlanTest.class
pm/SystemArchitectureFrame$1.class
pm/SystemArchitectureFrame$2.class
pm/SystemArchitectureFrame$3.class
pm/SystemArchitectureFrame$4.class
pm/SystemArchitectureFrame$5.class
pm/SystemArchitectureFrame$6.class
pm/SystemArchitectureFrame$7.class
pm/SystemArchitectureFrame$8.class
pm/SystemArchitectureFrame.class
pm/SystemArchitecturePanel.class
Which shows me that the class is there. I suspected that it might have something to do with CLASSPATH at first because of the java.lang.NoClassDefFoundError, but now I am skeptical that that could be the problem. I even build a new jar file out of different classes to make sure my method was OK and that worked fine. Any ideas? Thanks for your help in advance.

Here is my Manifest:
Main-Class: pm.PMApp<carriage return>
Class-Path: C:/j2sdkee1.3.1/lib/j2ee.jar<carriage return>
I noticed that if I leave the Class-Path variable unset it has no problem finding the class pm/PMApp, but I then get a class loader error concerning J2EE stuff. Am I missing something in my Class-Path? I tried to even specify the jar file I'm running here, but that didn't work either? I have also tried '.' and './', space delimited in my Class-Path, like this:
Class-Path: . ./ C:/j2sdkee1.3.1/lib/j2ee.jar<carriage return>
Thanks for the replies, do you have any more suggestions?

Exception in thread "main" java.lang.NoClassDefFoundError: rep.jar in linux

Hi
I am new to java and am trying to deploy a code on linux red hat 4.I have 5 files namely:
1.ClassReportGenerator.java
2.ClassScheduler.java
3.manifest
4.rep_compile.sh

first the rep_compile.sh is used to generate the class files for the two java files and then it creates a jar file

Wierd java.lang.NoClassDefFoundError (not in MAIN!!!)

hi,
i'm working on an open source java program for sharing legal bootlegs of band's shows (http://www.furthurnet.org). Anyway, after the client runs for a while, something goes afoul. The symptoms are:
press a gui button, which uses a callback -- nothing occurs
stderr prints (among others classes w/ same error):java.lang.NoClassDefFoundError: furi/RemoteFile
at furi.Search.processResponse(Search.java:156)
at furi.MsgManager.processQueryResponse(MsgManager.java:218)
at furi.ReadWorker.handleQueryResponse(ReadWorker.java:758)
at furi.ReadWorker.processIncomingData(ReadWorker.java:358)
at furi.ReadWorker.run(ReadWorker.java:154)
at java.lang.Thread.run(Thread.java:534)
As you can see, this client runs multi-threaded, in fact, there are quite a few threads running at any given time. The codebase for this is quite old, and thus quite a mess. The interesting thing is, apparently, many of the other threads continue to run fine.
Another note: I've not seen other folks w/ the client reporting the same problem (but the client is buggy & the users may be conditioned to ignore :) ). I suspect that there is a memory leak or something goofing up the VM, but what do I know?
Also, i've seen it occur on 2 of my computers, both running linux (fedora core 1)
Here are my specs:
I'm running fedora core 1 - 2.4.22-1.2188.nptl
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
java -Dfurthur.syscfgdir=/home/jonco/.furthur/ -jar /home/jonco/bin/Furthur.jar
note: my CLASSPATH is currently blank (but i thought that since it ran from .jar, it didn't matter) -- it is also blank on my other computer as well.
any help would be greatly appreciated.
thanks,
jonathan

The cause of the error is the same regardless of in which thread it happens: a class that is needed to run the program could not be found. The error message says exactly which class: furi.RemoteFile.
Is that class included in the .jar file /home/jonco/bin/Furthur.jar ?

Java.lang.NoClassDefFoundError with Novell GroupWise WebAccess Version 6.5

Before I upgraded to Tiger (10.4.4) yesterday from Panther (10.3.9) & the latest version of Safari (I did not write down the exact version as I wiped out my hard drive when upgrading), the Novell GroupWise WebAccess version 6.5 was working perfectly fine.
However, since the upgrade & using Safari 2.0.3 (417.8), I am getting the following error message after submitting my loginID and password.

I am getting the following error: Unable to locate class: java.lang.NoClassDefFoundError: on an iPlanet WS. We have ensured that the classpath in jvm12.conf includes the jar file with path. Any ideas?

Well, now I'm pulling my hair out even more because I can't get it to resolve anything in jaxws-rt.jar at runtime. Note: compile-time still works FINE.
I was messing with classpaths and stuff (and the endorsed dirs option of course) and it was "working" to the extent I had posted before, but then I kept playing with it and at some point I said, this isn't working and I need to reset all this stuff back to the way it was.
... so I did that. And now it won't resolve "PolicyException:"
java.lang.NoClassDefFoundError: com/sun/xml/ws/policy/PolicyException
This doesn't mean anything to you guys I bet, but that happens when it FIRST gets inside the web service code, which references PolicyException (doesn't even use it at that point.. I'm assuming the import is screwing it up when it's in the constructor). So now it won't resolve at all. Before, it was getting past this point and telling me the "method not found" error on the next line or this same error for WSBindingProvider two lines down, when it's actually being used. AWESOME.
I downloaded the latest jaxws-rt.jar and all its dependencies, shoved that into my lib folder, and set the endorsed dir to that folder (There's kind of a web of dependencies here. jaxws-rt.jar expects all its dependencies to be in the same folder, it seems, so I don't know how it was "working" before when I just copied jaxws-rt.jar into my separate endorsed dir - but I can't move all of those files to endorsed because I need them in my project (which expects them to be in the lib folder)). What happened? It went back to my original "String" error (first error in the first post), which means it's not getting endorsed at all from that location.
What a mess.
Can someone tell me what the heck I'm supposed to do with this jar file?

JAR files + java.lang.NoClassDefFoundError

Hey all ...
I'm looking for little help with building JAR files. Here's the situation: (using ant script :))
I have few source files *.java which I include into JAR file with default MANIFEST built by ant. (these files should be implemented as LIBRARY.jar)
These files are classes, which I want to use in my Main.java class. But I want this Main, to be in independant executable JAR file, so I set Main-Class property to 'packagename/Main'.
Ofcourse in all files I have set package to my default package name. My question is, how can I force java to execute MAIN.jar and look for classes in my LIBRARY.jar
after executing command:
java -jar MAIN.jar I get java.lang.NoClassDefFoundError
Tanks for any ideas ...

Then all I can say in addition is that something isn't deployed correctly. You're not saying what class it isn't finding. For all I know it can't even find your main class to execute because maybe you don't have it deployed correctly in the right path structure within the jar. Or the path to LIBRARY.jar is wrong. Or some other problem. Don't know based on the portion of the error message you have displayed this far.

HELP:: jsse1.0.3 problem with jdk1.3.1(java.lang.NoClassDefFoundError)

Hi,
I am now working with jsse1.0.3 and jdk1.3.1(I can not use the new jdk version, because the system I developed is based on jdk1.3.1). what makes me strange is that I can compile my program without problem, but when I run it, it always report error.
my source code is :
import java.security.*;
import javax.net.ssl.*;
System.out.println("Classpath ->"+System.getProperty("java.class.path"));
SSLSocketFactory factory = (SSLSocketFactory)SSLSocketFactory.getDefault();
SSLSocket SSLcontrol_connection = (SSLSocket)factory.createSocket(ftp_server, 990);
SSLcontrol_connection.startHandshake();
..........the erroe message is:

I also tried to add

java.lang.NoClassDefFoundError
at com/sun/net/ssl/internal/ssl/Provider.<init> (DashoA12275)My developing GUI is eclipse 3.1, and the OS is winXP.
Please give me some help, thank you very much.

oh. I have found the problem. Acturally, the running enviroment is under microsoft j++, so it could only support jdk1.1, but jsse only support from jdk1.2, so that's the problem why it said that no class found.
Now I only found that oracle has a solution for SSL which support
jkd1.1(SUN's jsse package only support from jdk1.2). It described the
method and sample code in Oracle Advanced Security Administrator's
Guide Release 2 (9.2)

Thanks for all the help
Scott.

The directory hierarchy of your .class files must mirror the package hierarchy of your classes.
So if you've got a class "Foo" in a package "p1" (i.e. a class with the fully qualified name of "p1.Foo") and a clas "Bar" in a package "p2" (i.e. a class with the fully qualified name of "p2.Bar"), then you need a file hierarchy such as this:
p1/Foo.class
p2/Bar.classAnd the directory in your classpath needs to be the directory that contains p1 and p2.
So what you need to do is go to a directory that contains a directory called "Simple_Server" (your source file mentions SMTP_Server, but I assume you changed it at some point).
That directory Simple_Server must contain a file called Server.class.
Then execute "java Simple_Server.Server".
Also please follow common naming conventions, as your code will become harder to understand if you don't. An important rule in those conventions is that package names should be in all-lowercase and not contain any non-letter characters if possible (i.e. use "smtpserver" instead of "SMTP_Server").

Problems with Deploy java.lang.NoClassDefFoundError

JAR:Exeption in thread "main" java.lang.NoClassDefFoundError

Hello !
I desperatly tried for the last two month to Jar my files.
I used JBuilder and JCreator to build and run those programme.
And it works !
But when I trie to use the jar tools, the jar is created...but if I click twince on it, it says that it can not find the main function:
"Exeption in thread "main" java.lang.NoClassDefFoundError".
And when I try to run the .class or .java file, with the java tools, it says the same thing : it can not find the main classe.
I suspected that my manifest was not good, but then, why doesn't it work with the tools (and it works properly with Jbuilder!)...
I'm lost, if some one could help me, and give me good information and the way to do it, step by step, with an example, I'll be so thanksfull !
i.e.:
import java.*;
class Hello{
public Hello(){
public static void main(String args[]) {
System.out.println("Hello World!");
}Thanks !
.Splitsch.

You have to tell where the main class is.
prepare a text file mainclass.txt and write the following line.
Main-Class: classname
follow the same as i wrote above. leave a blanl after colon and a blank line after the first line like above.
after that execute the command.
jar umf mainclass.txt jar-file-you-created
then run you jar file as
java -jar jar-file-you-crated
phani.

Java.lang.NoClassDefFoundError - Oracle 9.0.2 with Tomcat 5.5.7

Hi all,
If I have post at a wrong forum, please let me know.
My problem is that, after installing Oracle 9.0.2 as a standalone db on my PC, some Java and Jsp classes don't run properly. I get the following error msg:
java.lang.NoClassDefFoundError: javax/xml/transform/Source
I think it may be a problem with path. For Java programs, I now use a bat file to set path to ignore "C:\oracle\ora92\bin;C:\Program Files\Oracle\jre\1.3.1\bin;C:\Program Files\Oracle\jre\1.1.8\bin;" in system's path like this:
set PATH_BAK=%PATH%
set Path=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\Program Files\Executive Software\Diskeeper\;"C:\Program Files\Symantec\Norton Ghost 2003\";C:\j2sdk1.4.2_06\bin;C:\j2sdk1.4.2_06\jre\lib\ext
java %1
SET PATH=%PATH_BAK%
The Java classes run properly with the bat file now. But would there be some better solutions? And how can I run the JSP programs again?
Really appreciate for any suggestion / help. Thanks very much in advance.

Hi all,
I have further located the problem -- if remove from path "C:\Program Files\Oracle\jre\1.3.1\bin", the Java classes works again.
But what problem would occur if it is removed from path permanently? Any suggestion? Thanks very much.

Help with error "main" java.lang.NoClassDefFoundError:

I am pretty new to Java and I just install the JDK1.4.2 03
I am getting an error when I run the class file TestChart.class with the

I have several class files in the directory d:\personal\java-ChartGen
Chart.class

All these files are for the program.
Can some one help me why is this happening?? Is there something I can do
that I am missing???
I tried using the -CLASSPATH to direct it to the same directory but still
with the same error.
Please help me. Thank you

I use the command line as follows:
c:\j2sdk1.4.2_03\bin\java d:\personal\java-ChartGen\TestChart.class
The full error message is as follows:

I thought it may be the CLASSPATH, but all my class files are located in the

Connecting with ODSM to OVD fails caused by: java.lang.NoClassDefFoundError

Hi,
I have made a fresh new install of an Oracle Virtual Directory server running on Windows 2003 32-bit and an ODSM server (Weblogic) running on Windows 2003 64-bit using FMW Identity Management 11.1.1.2 for both OVD and ODSM (OVD of course being 32-bit and ODSM the 64-bit version).
When I try to connect with ODSM to my OVD server the first time without using SSL and connecting to port 8899 I get a pop-up telling me to look for a "Server Exception during PPR, #1" error in the log. The log shows me indeed a javax.servlet.ServletException: javax/wsdl/OperationType caused by Caused by: java.lang.NoClassDefFoundError: javax/wsdl/OperationType Caused by: java.lang.ClassNotFoundException: javax.wsdl.OperationType.
When I try it a second time with the same settings it tells me to look for a "Server Exception during PPR, #2[[" in the log. The log now shows me a javax.servlet.ServletException: Could not initialize class com.octetstring.vde.admin.services.client.VDEAdminServiceSoapBindingStub Caused by: java.lang.NoClassDefFoundError: Could not initialize class com.octetstring.vde.admin.services.client.VDEAdminServiceSoapBindingStub.
Connecting using SSL fails with the same error as the second attempt without it except the error is now #3.
Any idea what might be going wrong here? Could it be the firewall between ODSM and OVD? Is it using more than port 8899 to connect? Or is it the difference between 32/64 bit platform and the 64-bit JVM that is missing some classes? What is it?
Thanks in advance,
Bart.

Hi,
I got the environment working.
Here is the environment details

Seems to be a CLASSPATH problem. Try:
java -cp . ExampleProgramIt should help. (Beware there are three arguments, the . is the second.)
Maybe you have a classpath variable set where the path doesn't contain the working directory (the "."). You may then consider adding it to the end.
Hope it helps
