Java.lang.numberformat exception

Hi,
I have a situation wherein i am trying to assign a integer parameter value (coming from a SQL Server Stored Procedure) into an int variable in the program and i am getting the above exception.
The data format is same in the sense, incoming parameter can have a possible value of 0 or 1 or 2. The local variable in the program is initliazed to 3.
Please let me know if you have a solution.
Regards
Ramesh

What is the line of code causing the Exception? What is the datatype that the stp returns and what is the datatype of the column in the db?

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.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.

Java.lang.ClassNotFound Exception whenever I include .send()

Everything runs fine, but when I add the .send(message); [it is in bold] I get a java.lang.ClassNotFound Exception.
It still compiles, it just won't allow me to launch the program in the emulator. If I take that one piece of code out, everything runs fine again. I've been messing with it, and searching for a long time in an attempt to solve the problem but I've yet to come across a solution.

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_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 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.

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

Why do I get a java.lang.OutOfMemory exception

Thanks, in advance, for you help.
I just wrote a fairly large program. Every time I run it, I get a java.lang.OutOfMemory exception. I have no idea how to debug my code. Why would I get such an exception and how would I debug it?

put more debug statements
and see which line its giving that exception and see whether some where u have any line which is kind of looping or memory allocation .
As i havent seen ur code thats vague idea iam giving
java.lang.OutOfMemory exception is Thrown when the JVM cannot allocate an object because it is out of memory, and no more memory could be made available by the garbage collector.
hope this might help

Reason of java.lang.NoSuchMethodError exception

Hi,
I observed some strange (I suppose) behaviour. I made some helper class, which works as a factory to some EIS. When I use it in test desktop Java client, works correct, but if I try to involve it into the some servlet than I'll get an
java.lang.NoSuchMethodError
exception. Why it doesn't work as a servlet?
Thanks for som help
Krzysztof

Java.lang.NullPointer Exception error in webi

Hi All,
When a opening a webi report a user is getting java.lang.NullPointer Exception error in webi for a single report.
Other reports which were build from same universe are working fine. The issue is only with one user and one report.
Environment:
Business Objects XIR3
Java 6 ,update 3
IE version 7
Web Application Server - Apache Tomcat
Thanks in Advance....

Hi,
Check whether the same user is able to open the report in some other machine?
What happens when the user is trying to open other reports? Does he gets the error again?
If the reports is working with other machine, check the java version of the machines.
If the report is working with other users, it not possible that the universe is damaged.
This issue cannot be a rights issue. It has to be something with the report, java, or the universe.
Please check the above details and let me know.
Regards,
Shreyash.

Java.lang.outofmemory exception

Hello,
I have an application, that writes several thousands of records into a file and transfers the same to the server. I am encountering an exception "java.lang.OutOfMemoryError" exception.
I had checked this forum earlier and found a solution that recommended an increase in the memory slot allocated to the JVM. Despite, an increase in this slot from 256MB (eclipse's default) to 1024 MB, my problem still persists. I had updated the eclipse.ini field from "-vmargs -Xms40m -Xmx256m" to "-vmargs -Xms40m -Xmx1024m". Is there anything else that I need to do, to take care of this problem? I am using green threads in the application, does this have anything to do with the above mentioned exception?
Thanks!

I am using
green threads in the application, does this have
anything to do with the above mentioned exception?It wouldn't be hard to find out. Create a new java class where the main method does the same work; writing several thousands of records into a file and transferring it to the server.
Maybe it's all the other variables you have in your application that are cutting into the memory. But can you really reduce them?
Are you loading all thousands of records to memory (I'd imagine in a hashmap or a list) all at once? Like said, do this in smaller chunks, store the records in memory just one at a time and see if that works. It will be slow but it won't run out of memory. Then increase your "batch size" until you find the optimum.
