MultipartFormHandler - java.io.EOFException

Hi,
I've tried to upload a file using UIX.
In the event handler, when I do
"new MultipartFormHandler( context.getServletRequest() );"
a java.io.EOFException occurs:

Getting "java.io.EOFException" while reading a file

I am getting this error when trying to upload a file through the html form to the server.
I am using Struts form and the FormFile to get the file contents. After getting the file contents I write to a file in the server path. This works perfectly with WebSphere4.0.
When I deploy my application in Websphere 6.0 cluster environment I get the following error.

while((obj=input.readObject())!=null)and what's this test for? Where does it say that readObject() can return null? Is it really the correct test for what you're testing for?

Java.io.EOFException

Hello,
I am getting the following error while calling a remote IF method of a stateless
EJB.
com.ibi.agent.TuxAgent : UnmarshalException : error unmarshalling arguments; nested
exception is:
java.io.EOFException
com.ibi.agent.TuxAgent: error unmarshalling arguments; nested exception is:

Has anyone encountered this error while accessing the Remote IF methods. If so,
what you did to resolve this problem? Any help would be greatly appreciated.

Apurb,
The problem is resolved.
I tried to pass a hashtable of Tuxedo wrapper objects of type TypedFML. They were
told to be implementing java.io.serializable.
Then, when I tried to serialise/deserialise the object, i got an EOF Exception.
So, I just passed a simple java type as parameter to my rmi call and made the
EJB to handle the building of those wrapper classes.
Thanks,
Aravind.

Thanks for your replies !!
In any of the RPD deployments I'm getting the same error , not for some particular RPD .
FYI , yesterday (before this issue) I had a issue with starting presentation services , so as adviced in forum I replaced the files sawguidstate and sawguidstate.atrin the location:
<Instance_Home>\instances\<instance_name>\bifoundation\OracleBIPresentationServicesComponent\coreapplication_obips1\catalog\<project>\root\system\mktgcache\<name>
with the same files from a backup or from another working OBIEE 11g (11.1.5)instance.
plese refer : Re: Unable to start presentation services , in OBIEE 11g
Is this causing the deployment issue ?

Hi,
Don't know which of this factors solved the problem:
1. Error server:
AIX 5.2
jdk 1.3.17 (minimum from docu: 1.3.11)
$ORACLE_HOME wasn't in the begining of $PATH
2. success server:
AIX 5.3
jdk 1.4.02
$ORACLE_HOME is now in the begining of $PATH

My suggestion would be to run your code as a plain old Java application. Why use a servlet environment to test the problem? There's just too many things going on. So first see if it works the same way in a Java application. If it does, or if it doesn't, you then know where to go next.

How to deal with java.io.EOFException error in Java application?

Recently a java application called Jin stopped working on my iMac under 10.6.8. On startup it gives a java.io.EOFException error. When I boot from a full backup on external hard disk, the program still works fine. It has run without problem for at least two years.
This program logs onto an online chess community called ICC (see chessclub.com) using a non-http protocol.
I have tried everything I can think of to repair the problem, including:
-- Reinstalling both Jin and Java
-- Playing with Java Preferences, in particular trying both 32-bit and 64-bit versions
-- Discarding a couple .plist files associated with Java and Jin
-- Repairing permissions
-- Replacing /usr/share/java/Tools with version from backup disk (I created a Smart Folder to find files recently changes, and these were the only java files that came up
I've run out of ideas. It seems to me that some obscure Java support file has been corrupted, but I have no idea what or where.
Is it a good idea to replace the entire /Library folder from backup, or is that going to cause a problem?
I have a very bad feeling about replacing /System from backup.

SOAP: call failed: java.io.EOFException: Connection closed by remote host

Hi folks,
my friday crusher:
We have a sync RFC-PI-SOAP scenario.
All is working fine in Dev system.
After moving into Test following error is displayed as the SOAP response message:
- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">
<SAP:Category>XIAdapterFramework</SAP:Category>

<SAP:P1 />
<SAP:P2 />
<SAP:P3 />
<SAP:P4 />
<SAP:AdditionalText>com.sap.engine.interfaces.messaging.api.exception.MessagingException: java.io.EOFException: Connection closed by remote host.</SAP:AdditionalText>
<SAP:Stack />
<SAP:Retry>M</SAP:Retry>
</SAP:Error>
Also Channel Monitoring says:
Message-Verarbeitung fehlgeschlagen. Grund: com.sap.engine.interfaces.messaging.api.exception.MessagingException: java.io.EOFException: Connection closed by remote host.
Couldn´t find any hints in SDN and the web to this issue.
Does anyone of you has made experiences with that problem?
Maybe it´s a system parameter for time out SOAP connections....?
Many thanks for your help
-and-
have a great weekend!
Cheers
André

Very strange!
But I have the solution:
I have looked into channel monitoring / RWB again.
There I saw, this PI is using two clusters on two application servers.
Everytime the SOAP call is executed through the frist cluster, all was fine.
But no SOAP call was successfully executed by the second cluster.
Fortuity? No!
The second cluster node / app server wasn´t registered for internet access in the used proxy server.
So it wasn´t an PI issue.
Now, all is fine & I´m happy!
Thanks @all for helping!
Cheers,
André

SOAP: call failed: java.io.EOFException

Hi all,
I have build a proxy to soap scenario that generates errors during runtime. The scenario
consists of an ABAP program consuming a webservice through PI. The communication
channel shows the following errorlog:
- Message processing started
- request entering
- SOAP: call failed: java.io.EOFException: Connection closed by remote host.
- Message processing failed. Cause: com.sap.engine.interfaces.messaging.api.exception.
MessagingException: java.io.EOFException: Connection closed by remote host.
Does anyone know the cause of this error?
Thanks in advance.
Regards,
Ivo

Hi Ravi,
although I was able to reach the URL through a webbrowser, this problem was indeed caused by unavailability of the webservice. I just tried the connection without making any changes in PI and everything is working fine now.
Case closed.
Regards,
Ivo

FRM-92100 java.io.EOFException

Hi,
I'm having an issue after upgrate to Developer 6 Path 17. Disconnected from Oracle Applications after user login with error:

Hi,
frm-92100 is a generic error and it happens when the network connection is lost.
There is a lot of documentation on Metalink about that. Take a look at Note 216639.1

Got java.io.EOFException error in Safari

I got this error when trying to access My Ebay.
Request failed.
Got java.io.EOFException (Unexpected end of ZLIB input stream): http://my.ebay.com/ws/eBayISAPI.dll?MyEbay&gbh=1
I've fixed this problem by configuring the Proxy server to No Proxy in Firefox, but I don't know where to find that in Safari.
Help please. Thanks.

Safari is set to Web Proxies under the Network prefPane, and I've never make changes to it. But the Request failed error just started happening recently.

}I'm stumped as to where it is going wrong. I know that packVectors() and unpackVectors() both work, as they are used in a local save function. I suspect the problem lies between the getWBContent(String hid) and the fileListener class, but I am not certain where. Any help would be appreciated.

First, you are expecting read(buffer,offset,count) to throw an EOFException. It doesn't, it returns -1 at EOF.
Second, you are using a Writer to write binary data (resulting from serialization). This will corrupt it. Use an OutputStream.
Third, what I really don't get is why would you (i) write local data to a file and (ii) start a new thread to (iii) read it back and (iv) send it over not one but two sockets, when you could just return the data as the result of the remote method without the file, the thread, or the Sockets.
And in any case this sort of thing is most definitely not what SwingtUtilites.invokeLater() is for. (What it is for is updating Swing components and ensuring it all happens in the Swing thread, being the only correct way to write Swing code as Swing is not thread-safe by design.) If your server has a Swing GUI, which doesn't seem likely, it will stall for the duration of all this I/O. If it doesn't, why start the Swing thread at all?
Just define a serializable object that contains all the data you are passing to writeObject()/writeInt() and return it as the result of the remote method.
You will save yourself a lot of latency and code in the process, and you could reduce all this to about six lines of code, something like:
return new WBContent(
PageHolder, //Pages to file...
ImgPage, //Images for the Pages to file...
WBStack, //Current object stack to file...
objCount, //Current object count to file...
pageCount, //Current page count to file...
pageCount-1 //Current page number to file...
); where WBContent is a serializable class with the appropriate members and constructor, and is the return type of getWBContent().

Sess_sh - java.io.EOFException error

I'm trying to configure mod_ose for use in stateful plsql web applications. According to the OSE User's Guide, I need to publish the plsql servlet using sess_sh. I'm able to connect using the following syntax.
sess_sh -s http:// webserver:portnumber -u
sys/change_on_installHowever, every command that I enter after I get the sess_sh prompt is "java.io.EOFException".
Any insight into this problem would be appreciated.

Hi ,
You can try this
sess_sh -u sys/change_on_install -s jdbc:oracle:oci8:@<tns_alias_for_database>

Hey BalusC
As i already obtain a new session object from sessionfactory,for one or more transactions at once(!),
For reference see below code:
package com.dao>hibenateUtil;
import java.util.*;
import com.ConsumerRecord;
public class ConsumerDAOHibernate implements IConsumerDAO {
     public Long getNumberMatchingQuery(ConsumerRecord upr){
         String query = new String();
        String queryStart = "select count(*) FROM person in CLASS com.ConsumerRecord";
        query += queryStart;
        org.hibernate.Query q = HibernateUtil.getSession().createQuery(query);
        return (Long)q.uniqueResult();
    public Long getNumberMatchingCity(ConsumerRecord upr){
         String query = new String();
        String queryStart = "select count(*) FROM city in CLASS com.ConsumerRecord";
        query += queryStart;
        org.hibernate.Query q = HibernateUtil.getSession().createQuery(query);
        return (Long)q.uniqueResult();
Hibernate Util:-package com.dao;

    private static Session session = null;
    private static Logger logger = Logger.getLogger(HibernateUtil.class.getName());
    static {

            /** TODO: change to IOC w/ datasource */
            Configuration conf = new Configuration();
            sessionFactory = conf.configure().buildSessionFactory();
        } catch (Throwable ex) {
            // Make sure you log the exception, as it might be swallowed
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
    public static Session getSession() {
        if(session == null){
            try {
                session = sessionFactory.openSession();

Using Document form varable results in failed unmarshalling message java.io.eofexception

Hi,
I'm on LiveCycle ES 8.2. For PDF submit forms from workspace, I assigned the servername for submit as URL:
http://adobe1234:8080/workspace-server/submit.
We are using Document Form variable for this process. The reason is the forms will be digitally signed at each stage and we dont want to loose their signatures if forms go next stage.
This works perfect when I submit the form.
Now, we will be moving all the existing instances to new server and I want this URL to be server independent.
I take off this URL and kept it blank and try to submit from workspace. Nothing happens if I click submit and the form stays at the same place.
I see the following error in the log file:
2012-03-29 15:07:17,541 ERROR [org.jgroups.protocols.UDP] failed unmarshalling message
java.io.EOFException
          at java.io.DataInputStream.readShort(Unknown Source)
          at org.jgroups.Message.readFrom(Message.java:630)
          at org.jgroups.protocols.TP.bufferToMessage(TP.java:973)

          at org.jgroups.protocols.TP$IncomingPacketHandler.run(TP.java:1296)
          at java.lang.Thread.run(Unknown Source)
I have to avoid using this URL in the form as I will be moving my system to new domain & DNS and for any existing process instances, if they try to submit the form, that will error out as the URL is pointing to another server.
Your help is highly appreciated.
Thanks,
kc

I don't think I read your first post thoroughly. I see now you are setting the URL to prevent the form from appearing altered. I don't use digital signatures, but can see the potential problem. My first thought was to put JavaScript in the form to set the URL, but that would likely cause the same problem. I probably can't be of much help with no experience using the digital signatures. Our forms are considered 'Signed' if a logged in user clicks approve. Have you deleted the Form Bridge and readded? There may be differences with the one in ES2.
I think you are also saying you can't set the URL server side before rendering the form because processes will launch under one domain then get changed later.
If you were able to use JavaScript to determine which URL to submit to, you could put that code in the Form Bridge code and I would think that would submit. The form is not being altered by the code. This is assuming the code snippet I copied out of the form bridge is really what is called.
/** Invoke the standard Submit action */
function submitAction(doc, url, type) {
    if ( BRIDGE_SUBMIT_URL != null ) url = BRIDGE_SUBMIT_URL;
    if ( BRIDGE_SUBMIT_TYPE != null ) type = BRIDGE_SUBMIT_TYPE;
    if ( type == null ) type = "PDF";
    if (url != null) {
        setFocus(null); // force current field focus out in 8.1 + readers (null op in previous versions)
//      doc.submitForm({cURL: url, bEmpty: true, cSubmitAs: type, cCharset: "utf-8"});
        doc.submitForm({cURL: url, cSubmitAs: type});
