SQLException: SQLState(JZ006)Are there any other sorts of exceptions happening? There is either a
DBMS/driver version mismatch or some other sort of non-weblogic
problem. We are simply trying to close an unneeded connection and
the Sybase driver is throwing an exception which is saying the
driver didn't expect the other end of the line (the DBMS) to hang
up so fast. One thing you can do is to turn off shrinking... Show
me your pool config.

Hi all!
Since I've spent some days now trying to figure out what was wrong with my file upload in Struts 1.1, I would like to share my solution with the rest of you in order to spare you for the same amout of wasted time I've spent :-)
My platform is Resin 3.0.8 and Struts 1.1. My problem was that JPEG's got corrupted when arriviving at the server. After a few days searching on the net, I tried with a plain servlet and the O'Reilly package, and the app worked perfect.
Here is my servlet:
package no.yourcompany.yourapp.servlet;

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

PersonRegistrationForm personRegistrationForm = null;
PortraitImage portraitImage = null;
ByteArrayOutputStream outputStream = null;
Part currentPart = null;
FilePart currFilePart = null;
personRegistrationForm = (PersonRegistrationForm) request.getSession().getAttribute(DsnSessionKeyConstantsIF.KEY_PERSON_FORM);
portraitImage = personRegistrationForm.getPortraitImage();
try {
MultipartParser parser = new MultipartParser(request, MAX_FILE_SIZE_IN_BYTES);
while ((currentPart = parser.readNextPart()) != null) {
if (currentPart.isFile()) {
currFilePart = (FilePart) currentPart;
outputStream = new ByteArrayOutputStream();
currFilePart.writeTo(outputStream);
// portraitImage is just a bean for encapsulating image data, not defined in this posting
portraitImage.setContentType(currFilePart.getContentType());
portraitImage.setImageAsByteArray(outputStream.toByteArray());
portraitImage.setOriginalFileName(currFilePart.getFileName());
break;
} // if (currentPart.isFile())
} // while ((currentPart = parser.readNextPart()) != null)
} catch (IOException ioe) {
// noop
// redirect to receipt page
ServletContext servletContext = this.getServletContext();
RequestDispatcher requestDispatcher = servletContext.getRequestDispatcher(PAGE_RECEIPT);
requestDispatcher.forward(request, response);

IOException: Premature end of POST data

Hi, I have a web application with Java 5 / Struts 1.2.4 running on OAS 10g. I have this error when I tried to get any option of the application. The application is deployed in Tomcat, Websphere, JBoss, Glassfish but it fails only in OAS.
This is the error trace:

I have a javascript code that builds all urls of the application, this is the javascript code:
function loadOptionMenu(context, grupo){
     var cargarUrl = false;
     var urlTpw = document.getElementById("urlTpw");
     var btnShortcut = document.getElementById("btnShortcut");
     var url = context + "/menu.do?";
     if (urlTpw!=null && urlTpw.value!=''){
          url = urlTpw.value + '&';
     if(btnShortcut.value!=""){
          cargarUrl = true;
          url += "shortcut=" + btnShortcut.value.toLowerCase();
     if (grupo!=null && grupo!=""){
          url += "&grupo=" + grupo;
     //alert('URL a cargar: ' + url);
     if (cargarUrl){
          cargar(url, true);
}Finally code above builds an url in this way:
http://localhost:8080/neon/menu.do?shortcut=con&grupo=ADMCONTRATO
I had been googling about error, in this post http://en.allexperts.com/q/JSP-Java-Server-3299/Question-request-class.htm answered a possible solution. I don't know if the order of the parameters in the url and the way that it were called is important. it must be? may be another cause?
Thanks for your help
Fernando G.

what does "initLog()" do with the request object (or any of the other calls which take the request instance)? are any of them looking at the stream/reader associated with the request?

Java.io.IOException: data error cyclic redundantie check

Dear all,
I did a fresh install of JDeveloper 10.1.3.2.0 with JHeadstart 10.1.3.26 on my computer. These are the versions we use.
I've made a database connection, so that's allright.
When I open JDeveloper and I try to add an Application, we allready have made(with the same versions) I get the next error in JDeveloper: xxx.jws was saved in version file format and cannot be opened with an older version of JDeveloper. The version is not mentioned...
In the terminal I get the messeage of my subject: java.io.IOException: data error cyclic redundantie check.
I'm sure i'm using the same versions.
Does anybody know what went wrong?
regards,
Marcel.

It's like the data stream is getting messed up...so I would think of a few things:
1) Bad memory?
2) Bad connections?
3) Bad disk?
4) Viruses
Anything that can screw up the data steam.
Other than that....maybe as simple as reinstall the JVM and put new compiled code out there and see if it behaves.

Java.io.IOException: Data error (cyclic redundancy check)

Dear everyone,
I have a utility that copys a file, using streams.
It has always worked fine, but I ran into an
exception this morning:
java.io.IOException: Data error (cyclic redundancy check)
from the call:
int bytes = fileInputStream.read(byteBuffer);
Would you know what this exception is about? I
haven't seen that exception after that, though.
So it's a bit puzzling. Any help, or clue towards
solving this problem is appreciated.
Thanks a lot!
George

What i dont get is in the entire stack trace i am not able to locate which of my application files is causing the errors
I searched on net and found a few root causes but i am not able to find out exactly which class file is causing the stack trace
Any suggestions are most welcome
Thanking in advance

Did you do something strange like writing the object out using the Servlet response's output stream and then attempted to redirect or forward a user to another page? That is usually how the IllegalStateException gets generated. You would still see a valid response from the caller's perspective, but since you attempted to forward or redirect after data has already been written to the stream on the server, an exception is thrown there.

Java.io.IOException: Corrupt form data: no leading boundary

Hi,
I am trying to upload pdf files using a servlet. The Enctype of the form which calls this servlet is multipart/formdata. I use O'Reilly upload component which uses the class MultipartRequest to do the uploading. The form has textboxes and textareas whose data is also submitted.
The problem is, when I try uploading with Greek text in these text area and textbox, I get the exception
java.io.IOException: Corrupt form data: no leading boundary: -----------------------------7d21b8c1502c0 != -----------------------------7d21c2c1502c0
Has anyone encountered this problem? Any help will be greatly appreciated.

Java.io.IOException: Resource not found: org/joda/time/tz/data/ZoneInfoMap

I've been attempting to develop test classes using the PowerMock and Mockito mock frameworks
I've developed the tests in Eclipse in windows XP (64 bit) and the tests run to completion with passes
One of the classes being tested references the joda-time-1.4.jar and this jar contains the resource org/joda/time/tz/data/ZoneInfoMap
I then attempted to migrate the development to running the unit tests in a Windows XP command prompt launched by Maven 2 (mvn)
I get test errors, but the nature of the error depends where I set my JAVA_HOME
a) if I set my JAVA_HOME to a standard Sun JDK (C:\Program Files (x86)\Java\jdk1.5.0_21), then I get the resource not found error for one test only - here is an extract from the exception:

Finally, running the tests on a unix host under the AIX OS launched with Maven 2 (mvn), I get the Resource not found: "org/joda/time/tz/data/ZoneInfoMap" error
None of these errors occur when running the tests in Eclipse, so there must be a different environment
I've not been able to track it down, so if anyone can throw any light or offer a solution, that would be much appreciated
Thanks for reading and any help

Java.io.IOException:Data has already been flushed to the client

hi,
will u please anyone tell about this exception? its very urgent to me?
i am getting exception when i ma forwarding a page in jsp.
exception is :
java.io.IOException : Data has already been flushed to the client.
my code where i am getting this exception is:
if(filled_var .equalsIgnoreCase("y"))
%>
<jsp:forward page="/editForm.jsp">
<jsp:param name="formNum" value="<%= formNum%>"/>
</jsp:forward>
<%
here i am getting that error. please help me to find a solution in this.

A forward can only be performed if the "response is not committed". The response is committed when:
1) you do a forward
2) enough data is outputted for the buffer to be flushed
3) you flush the buffer manually (or you do an include with a flush="true" for example)
It must be either 2 or 3 in the case of a JSP. So if you output a lot of data before the forward, make sure you try to do the forward BEFORE you output all that data.

Your error is because you have already flushed or closed your output stream. Your response is done but you are trying to forward after the fact.

Java.io.IOException: Failed to rename log file on attempt to rotate logs

Hello.
I'm currently using Weblogic 5.1 SP6 on WinNT Server 4.0 SP6.
I set the weblogic.properties file like this so that the "access.log" will
be rotated every day at midnight.
-- weblogic.properties --
weblogic.httpd.enableLogFile=true
weblogic.httpd.logFileName=D:/WLSlog/access.log
weblogic.httpd.logFileFlushSecs=60
weblogic.httpd.logRotationType=date
weblogic.httpd.logRotationPeriodMins=1440
weblogic.httpd.logRotationBeginTime=11-01-2000-00:00:00
-- weblogic.properties <end>--
The rotation has been working well, but one day when I checked my
weblogic.log, I was getting some errors.
I found out that my "access.log" wasn't being rotated (nor being written,
flushed) after this error came out.
After rebooting WebLogic, this problem went away.
Has anyone clues about why WebLogic failed to "rename log file?"

I suppose this is because I have set the HTTP log to be flushed every one
minute.
Thanks in advance.

I'm also getting this error on Weblogic 6.1.1.
It only occurs if you set the format to "extended".
Is there any fix or workaround for this?
