Java.lang.NoClassDefFound Exception ????

hai friends,
plz let me know why we will get java.lang.NoClassDefFound Exception?
thanks in advance

If you are getting it when you run the program from the command line, the most likely reason is you've misspelled the class name or not included its package correctly.
In most other situation it means you've got the classpath wrong.
Google for Java classpath.

"Exception in thread "main" java.lang.NoClassDefFound Error" in XP

I was creating programs just fine for awhile. Then, for some unknown reason, I start getting the runtime error message, "Exception in thread "main" java.lang.NoClassDefFound Error." I set my PATH in the following manner:
Start | Control Panel | Performance and Maintenance | System | Advanced | Environment Variables | Use Variables for Owner | PATH | Edit | C:\j2sdk1.4.2_04;C:\j2sdk1.4.2_04\bin;C:\j2sdk1.4.2_04\jre\bin | Ok | Ok | Ok
I then closed the dialog boxes and restarted my computer. I then tried to run a program that ran before, only to get the same runtime error! Can someone please help me???

NoClassDefFoundError happens because the JVM cannot find some class from your program, not because the OS cannot find your JVM (PATH regulates the latter, but not the former). JVM looks up classes in directories (or JAR files) specified through the -classpath option, like "java -classpath c:\myclasses MyMainClass". Read the online doc for the "java" launcher for more info.

Error:"exception in thread main:java.lang.noclassdeffound error.

Hi,
I am new to this java tech and programming. I just started learning and installed j2sdk1.4.0_03. I wrote a small hello world program and compiled it without any errors. When I execute the same using java hello command, I am getting an error like this: exception in thread "main" java.lang.noclassdeffound error. I am not able to resolve this issue. Please let me know the sol.

send the program u have typedUmm... Why?
Anyway @NovaKane: Welcome. Together with seifist and sunny we have at
least three new posters who show enough intelligence to find chuck's
solution (or one of the many hundreds of others like it) and the politeness
to thank him for it. What's the forum coming to?
If you need it there is a description of the classpath here:

Again, welcome. And thanks for raising the intelligence level (and politeness
quotient) of the fora.

What version of Windows are you running? autoexec.bat is used by 98. Others use the system variables. The classpath you show for autoexec.bat looks OK but the classpath you show for system variables looks wrong. It should be the same as what you show for autoexec.bat You do not need the sdk\bin directory in your classpath unless you plan to put classes there.
The NoClassDefFound error means that the java.exe command could not find the class that you specified. You did not post the command that you entered. You may have specified the class wrong. Otherwise, it is probably a classpath problem.

Java.lang.NoClassDefFound Error:msgsend

Hi,
I am trying to run my first Java Mail program, sending mail.
I had compiled the source - no Errors.
Now, when i try to execute it says
Exception in thread 'main' java.lang.NoClassDefFound Error:
I have download the JavaMail and JAF and has put the files under proper dir and verified the class variable. I am using Jdk1.3.

The reason of this run time error is : Java is not able to locate main method of specified class File. or class file itself is not locatable.
Check :
1. Either u are not in same folder where ur class file is.
2. or If u are running from some other directory, ur class file path is not in CLASSPATH.
3.or There will be some mistake in definition of main method.

Could not find the main class. & java.lang.NoClassDefFound error:

sir / madam
I am facing problems with j2ksdk1.4.0 beta instalation on my windows 2000 advance server.
while installing pops up a message saying could not find the main class.
while using java or javac it says
Exception in thread main
java.lang.NoClassDefFound error:
com/sun/tools/javac/main
even when double clicking java plugin from the control panel
I get the Java virtual machine launcher saying could not find the main class.
I don't have any other java sdk installed.
And i have my environment variables (classpath, path and java_home) set correctly.
this same j2sdk1.4.0 version is installed in the windows 98 system and it's working fine.
Kindly do help me to solve this problem.
eagerly awaiting for your response.
Thanking you
Sajeev Nair
[email protected]

you must check with the classpath
please see that you have not repeated %classpath%
at the end of the class path like you do in win98.
similiarly with %path%
in win2000 it is automatically taken care off.

Java.Lang.NullPoint.Exception in OWB Mapping

Hello Everybody
We are building Data Warehouse using OWB Repository 9.2.0.2.0. When we are validating or deploying the created map we are getting Java.Lang.NullPoint.Exception. This leads to blank screen. We are unable to recover the map. Sometimes, synchronization works to recover the map, but not all the times.
Is there any solution to it?

Java.lang.thread exception while using Xalan 2.0 in WLS 6.0

Hi, I'm trying to use Xalan 2.0 in a servlet hosted by WLS. Ive
modified Xalan's SimpleTransform sample to be a servlet. I
create a Transformer with the .xsl, then call tranform() to
print the tranformed xml to the response stream. The xml is
tranformed correctly, but it throws a java.lang.thread
exception. The standalone Xalan sample doesn't do this. Anyone
else seen this problem?
Here's the code of interestest, I apologize if its not formatted very well:
public void doGet(HttpServletRequest req, HttpServletResponse res) throws IOException
     PrintWriter out = res.getWriter();
     res.setContentType("text/html");
     out.println("<html><head><title>XalanTest<title></head>");
     out.println("<body><h1>XalanTest</h1>");
     try{
     TransformerFactory tFactory = TransformerFactory.newInstance();
     StreamSource ss = new StreamSource("file:\\\\My-path\\birds.xsl");
     Transformer transformer = tFactory.newTransformer(ss);
     StreamResult SR = new StreamResult(out);
     transformer.transform(new StreamSource("file:\\\\My-path\\birds.xml"), SR );
     catch(Exception e){
     out.println("<p>" + e.toString() + "</p>");
     e.printStackTrace(out);
     out.println("<p>Exception</p>");
          out.println("</body></html>");

It also looks like the workaround suggested does not work.
I put the following code as workaround:
     response.setContentType("text/html");
     response.setHeader ("Pragma", "no-cache");
     Transformer transformer;
     TransformerFactory factory = TransformerFactory.newInstance();
     String stylesheet = "config\\closs\\applications\\webroot\\jsp\\example\\Load2.xsl";
     String sourceId = "config\\closs\\applications\\webroot\\jsp\\example\\Load2.xml";
     String outputFile = "config\\closs\\applications\\webroot\\jsp\\example\\Load2.html";
     String outputDirectFile = "config\\closs\\applications\\webroot\\jsp\\example\\Load2_Direct.html";
     try
          PrintWriter fout = new PrintWriter (new FileOutputStream (outputFile));
          OutputStream os = new ByteArrayOutputStream();
          transformer = factory.newTransformer(new StreamSource(stylesheet));
          transformer.transform(new StreamSource(sourceId), new StreamResult(outputDirectFile));
          transformer.transform(new StreamSource(sourceId), new StreamResult(os));
          os.flush ();
          os.close();
          out.print(os.toString());
          fout.print (os.toString ());
          fout.flush ();
          fout.close ();
     catch (Exception e)
          // Error Handler
     e.printStackTrace();
The two .html files produced look exactly the same, which is good.
However, the screen output to my html browser (Internet Explorer 5.50 sp1) produces
different output.
That is strange, but that shows that this bug does not have a known workaround

I have the same problem with java sun xml parser (jaxp 1-1)
It is interesting to know that all this perfectly works under weblogic
5.1, so
I cannot migrate my application to 6.0
So, the functionality of weblogic 6.0 degraded since 5.1.
I cannot buy the explanation that that is not bea's fault, because it
perfectly
worked with the same version of xml parser.
Now, their customer support is saying they have not decided whether this
is a
bug or a feature.
Interesting to know that degradation of functionality could be a feature!
It is now June 21, 3 months since this bug was reported, sp2 was shipped
since
that time, and this bug is still there.

org.apache.xalan.transformer.TransformerImpl.run(TransformerImpl.java:2894)
at java.lang.Thread.run(Thread.java:484)
What happened is: to support incremental output, Xalan-Java performs
the
transformation in a second thread while building the source tree inthe
main
thread. So Transformer.transform() creates a new thread to run the
transformer.run() method, which will write to weblogic's internal
ServletOutputStreamImpl, and in the end calls flush() on it.
ServletOutputStreamImpl determines that the headers haven't been written
yet, and the headers need to be written before any servlet output, so
it
calls ServletResponseImpl.writeHeaders(), which eventually calls
ResponseHeaders.setDateHeader(). The last method assumes the thread
is
weblogic's internal ExecuteThread and tries to cast the thread as such,
maybe to get the date from it. But the thread is a plain java.lang.Thread
created by xalan, thus we get the java.lang.ClassCastException:
java.lang.Thread
This suggests a second workaround: call ServletResponse.flushBuffer()
before any xalan stuff, which will force the headers to be written in
weblogic's ExecuteThread. The shortcoming of this is that this will
cause
the response to be commited, and if the xalan stuff throws exception
you can
not forward to another page.
Another thing is that xalan should not directly call flush() on
ServletOutputStreamImpl at all. I will report it to xalan and see if
they
consider that a bug. If they fix that then we have a third workaround:
set
the buffer size of ServletResponse big enough to accomodate everything
including the xslt outputs, so the ServletOutput does not need to be
flushed
during xalan code.
I do not consider this problem a weblogic bug, since the servlet container
has to right to expect any thread inside it to be its own. Serlvet2.2
spec
says:
1.2 What is a Servlet Container?
A Servlet Container may place security restrictions on the environment
that
a servlet executes in. In
a Java 2 Platform Standard Edition 1.2 (J2SE) or Java 2 Platform Enterprise
Edition 1.2 (J2EE)
environment, these restrictions should be placed using the permission
architecture defined by Java 2
Platform. For example, high end application servers may limit certain
action, such as the creation of
a Thread object, to insure that other components of the container are
not
negatively impacted.
Weblogic should explicitly warn the developers that creating threads
inside
the servlet container may have adverse effects, the same kind of problem
we
are having. (or maybe they already did somewhere in their documentation?)
On the xalan side, I would suggest them to either give the option to
switch
the two threads, or to give the option to buffer the output and write
it out
in the main thread, which is exactly what you did in your first workaround.
Any comments or thoughts on the subject are welcome.

"MK Parini" <[email protected]> wrote in message
news:[email protected]...
I found, what I think to be a bug, and a work-around for it.
When doing an XSLT Transformation, you must specify a StreamResult
to which to write the output. I was doing my transformation in
a
servlet so I was writing my output to the HttpResponse
(The variable res is a javax.servlet.http.HttpServletResponse
object)
StreamResult htmlTarget = new StreamResult(res.getWriter());
If I use this, when I perform the transformation using the TRAX
APIs,
InputStream xslFile = context.getResourceAsStream(fileName);
TransformerFactory tFactory = TransformerFactory.newInstance();
Templates xslTemplates = tFactory.newTemplates(new StreamSource(xslFile));
transformer = xslTemplates.newTransformer();
transformer.transform(xmlSource, htmlTarget);
I receive the ClassCastException from the class
weblogic.servlet.internal.ResponseHeaders.setDateHeader(ResponseHeaders.java
:273),
as seen in my previous posting.
I discovered, if I write my output to a StringBuffer, and then
I write
the StringBuffer to the HttpResponse, I do not get the ClassCastException.
For example,
StringWriter myWriter = new StringWriter(2400);
StreamResult htmlTarget = new StreamResult(myWriter);
<Same transformation code as above>
myWriter.close();
PrintWriter out = res.getWriter();
out.print(myWriter.toString());
Is this a bug in the weblogic internal servlet class or am I just
missing something?
Also, one concern that I have with the workaround is that it might
hurt performance.
Any comments or thoughts on the subject are welcome.

To expand on that a little, so that you get better information next time:
This line tells you what, ultimately, failed.
java.lang.IndexOutOfBoundsExceptionYou then get the stack trace from most recent method called to least recent method called. The most recent method will contain the line of code that actually failed, but as here may be in an external library:
at com.sun.imageio.plugins.jpeg.JPEGImageReader.gotoImage(JPEGImageReader.java:448)The last external package after your own code will be the method call that failed. Here you were calling the getImageMetadata() method of the com.sun.imageio.plugins.jpeg.JPEGImageReader class. Documentation on this class is available from the [Sun API documentation|http://java.sun.com/j2se/1.5.0/docs/api/javax/imageio/ImageReader.html] .
at com.sun.imageio.plugins.jpeg.JPEGImageReader.getImageMetadata(JPEGImageReader.java:851)The next entry indicates which line of your own code failed. Here it was line 45 which is within a method called execute (mediocre name - it should describe what it's doing, execute is too abstract) of your own class called mergeImagesHCL (also a poor name - classes should always start with a capital letter):
at mergeImagesHCL.execute(mergeImagesHCL.java:45)The rest of the stack trace tells you how you got there - here by calling mergeImagesHCL at line 84 of the main method of the same class:
at mergeImagesHCL.main(mergeImagesHCL.java:84)Stack traces tell you exactly what line of code your error is on, what you were calling when it failed, and why it failed. Use them.

Weblogic 8.1 SP4 getting Java.lang.outofMemory exception

Dear experts,
We are running WL8.1 SP4 on our Solaris 5.9 Server.
We want to do MQ implementatin on this server and for the same some kernel parameters were changed.
now our system has below parameters in /etc/system:
set semsys:seminfo_semmsl=1000
set semsys:seminfo_semvmx=32767
set shmsys:shminfo_shmmax=4294967295
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmseg=2048
set shmsys:shminfo_shmmni=2048
set semsys:seminfo_semmni=1024
set semsys:seminfo_semaem=16384
set semsys:seminfo_semmap=1026
set semsys:seminfo_semmns=16384
set semsys:seminfo_semopm=100
set semsys:seminfo_semmnu=16384
set semsys:seminfo_semume=256
set msgsys:msginfo_msgmni=50

set msgsys:msginfo_msgssz=16
set msgsys:msginfo_msgseg=8192
set rlim_fd_cur=10000
set rlim_fd_max=10000
and below in /etc/profile:
ulimit -s unlimited
ulimit -d unlimited
but as soon as server was rebooted and we tried to start the weblogic we got java.lang.outofmemory exception.
details as below:

need help to identify what exactly went wrong and where.
Thanks

Hi,
As you are using WLS8.1 It means your JDK will be JDK1.4 and there is a Bug already available with JDK1.4 for the Same issue ... Please find the below link:
http://bugs.sun.com/bugdatabase/view_bug.do;:YfiG?bug_id=4705373 (For Sun JDK1.4)
AND
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6373059 (For Sun JDK 1.5.0_05)
Please try to switch to JRockit JDK.
Thanks
