Java.io.EOFException while returning a large object using RMI

Hello
I am having an issue with RMI which seems to be quite common (given the given the amount of matches in Google) but for which I can find a way out.
In my application there 2 RMI objects , say OBJECT1 and OBJECT2. For OBJECT1 to get stuff from the database it gives a call to OBJECT2, which in turn fetches it from the DB and provides it back to OBJECT1.
It is in such a call from OBJECT1 that i get the following exception.
Caused by: java.rmi.UnmarshalException: error unmarshalling return; nested exception is:
java.io.EOFException
at sun.rmi.server.UnicastRef.invoke(UnicastRef.java:164)
at CALL FROM OBJECT1

The rows retrieved from the DB are stored in a user-defined array (serializable incl. all the subcomponents except for the primitive data fields) and the same is return back from OBJECT2.
Interesting thing is that this exception occurs only when the number of rows retrieved by OBJECT2 is exceeds a certain limit, i.e. when the no. of rows are less the application works perfectly.
Tried the following based on what was mentioned in different posts: Added following parameters to the JVM startup call.
-Dsun.rmi.server.exceptionTrace=true - did not get any pointers
-Dsun.rmi.log.debug=true
-Dsun.rmi.transport.connectionTimeout=600000 - cause the time for the DB query was above the default time of 15 sec
I am using Sun j2sdk1.4.2_13 for the application.
Any pointers to resolve this issue would be greatly appreciated.

The issue is solved by increasing the VM max. memory parameters!if you want to avoid issues like this in the future, check out RMIIO. it provides an api for a "streaming remote iterator" over rmi, so you wouldn't have too read all this data into memory at once (causing memory exhaustion issues).

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?

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 ?

Accessing Large object Using DB_LINK

RequestTimeoutException error while invoking a BPEL process using RMI

Hi,
I am getting RequestTimeoutException error while invoking a BPEL process using this code:
Locator locator = LocatorFactory.createLocator(jndiProps);
String compositeDN = "default/"+processName+"!1.0";
Composite composite = locator.lookupComposite(compositeDN);
String serviceName = "client";
Service deliveryService = composite.getService(serviceName);
NormalizedMessage nm = new NormalizedMessageImpl();
nm.getPayload().put("payload", requestXml);
NormalizedMessage res = deliveryService.request("process", nm);

To add to it the BPEL process is executing successfuly and RMI call timeout is happening.
Can I know how to increase the related timeout value?

Have got the same problem. Scenario at my end is little different though.
I am trying to invoke a BPEL process from an ESB Service.
I am trying to look into it..
However, would be grateful, if someone can give some insight into this since many are running into this issue without being able to fix.

JAVA&SOAP:how to return a complex object( the object has an object within)

Lets say my Complex object is :
public class PersonWithAddress {
private String name;
private int ssn ;
private Address add;
PersonWithAddress() {
name="Gagan Tandon" ;
ssn =1111;
add = new Address("1113","WestPlum Street");
public String getName() {
return name;
public int getSSN() {
return ssn;
public Address getAddress() {
return add;
This complex object has Address object embedded in it.
public class Address {
private String house;
private String street;
public Address (String myHouse,String myStreet) {
house = myHouse;
street = myStreet;
public String getHouse() {
return house;
public String getStreet() {
return street;
My deployment Descriptor is as following: check the mappings part.
<isd:service xmlns:isd=
"http://xml.apache.org/xml-soap/deployment"
id="urn:xml-soap-person-demo">
<isd:provider type="java"

And in my SOAPRPC code at client end calls the following: check the mappingregistry code...
String serverHost = "http://localhost:8082/soap/servlet/rpcrouter";
SOAPMappingRegistry smr = new SOAPMappingRegistry();
Parameter p= null;
try {
System.out.println("here 0");
Response r=null;

Vector parameters = new Vector();
System.out.println("here 1");

// parameters.addElement (new Parameter("name", String.class, "Web Services Client", null));
// c.setParams (parameters);
c.setSOAPMappingRegistry(smr);

smr.mapTypes(Constants.NS_URI_SOAP_ENC,new QName("urn:xml-soap-person-demo","Address"),Address.class,beanSer,beanSer);
smr.mapTypes(Constants.NS_URI_SOAP_ENC,new QName("urn:xml-soap-person-demo","PersonWithAddress"),PersonWithAddress.class,beanSer,beanSer);
try
System.out.println("here 4");
r = c.invoke ( new URL(serverHost), "" );
// org.apache.soap.SOAPException can be thrown
catch ( Exception e )
e.printStackTrace();
// Check the response.
if (r.generatedFault ()) {
Fault f = r.getFault();
System.out.println ("Error Occurred: ");
System.out.println (" Fault Code = " + f.getFaultCode());
System.out.println (" Fault String = " + f.getFaultString());
// return f.getFaultString();
// return new String("gagan");
return null;
else {
System.out.println("here 5");
p = r.getReturnValue();
System.out.println("here 6");
// System.out.println( (String)greeting.getValue() );
System.out.println("SSN: " + ((PersonWithAddress)p.getValue()).getSSN());
return (PersonWithAddress) p.getValue();
catch( Exception e ){
e.printStackTrace();
// finally {
// return null;// String("not OK");
if (p==null)
return null;
else
return (PersonWithAddress) p.getValue();
When running this code..
The following error is thrown.
System.out.println("here 4") is printed.

}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().

Java.io.NotSerializableException - while retriving "one to many" objects

i am getting java.rmi.MarshalException java.io.NotSerializableException
while i try to retrive one to many objects
i have recently migrated from kodo 2.5.x to kodo 3.0.1, and i have parent
object reference in child objects (reverse mapping reference according to
kodo 2.5.x) as shown below
public class BankStatementEntry implements BankStatement {
private Set accountSummary = new HashSet();
public interface BankStatement extends Serializable {
* Returns the accountSummary.
* @return Map
public Set getAccountSummary();
* Returns the accountSummary.
* @return Map
public void setAccountSummary(Set accountSummary);
public class AccountSummaryRecord implements AccountSummary {
private BankStatementEntry bankStatementEntry;
public interface AccountSummary extends Serializable {
     * Returns the transactionDetails.
     * @return Collection
     public Set getTransactionDetails();
the problem is, when i try to retrive BankStatementEntry object, i have to
iterate through each child (AccountSummaryRecord) object and manualy
remove parent object reference (BankStatementEntry) by setting null.
Otherwise EJB throws java.io.NotSerializableException
Is this bug ?
Thanks
karup.

Proc_getObject with nolock causes "read operation on a large object failed while sending data to the client"

SharePoint 2013 code for the SharePoint Config database stored procedure dbo.proc_getObject has been changed from SharePoint 2010 with the difference of select with nolock.
I am seeing numerous Error 7886, Severity-20 errors nightly:
"A read operation on a large object failed while sending data to the client. A common cause for this is if the application is running in READ UNCOMMITTED isolation level. This connection will be terminated."
Here I have commented out "with (nolock)" to 'fix' the error and to align the store proc with SharePoint 2010 code :
ALTER PROCEDURE [dbo].[proc_getObject]
@Id uniqueidentifier,
@RequestGuid uniqueidentifier = NULL OUTPUT
AS
SET NOCOUNT ON
SELECT
Id,
ParentId,
ClassId,
Name,
Status,
Version,
Properties
FROM
Objects --with (nolock)
WHERE
Id = @Id
RETURN 0
How is this stored procedure called and for what use?
Why did Microsoft make this change to SharePoint 2013 - some performance gain through dirty reads at the cost of stability? Or what could be a reason for this to happen that can be fixed?

GetObject retrieves any farm object that is selected (by ID). Changing this is obviously not supported, and NoLock was used to (help) prevent locks when performing a select query.
I've never seen this issue, and would guess it is unique to your environment given this is such a core piece of the SharePoint infrastructure.

Java.util.Calendar returning wrong Date object

Example: This was my scenario last night. A server in California has date/time of 'Mon Aug 18'. Current time in Indiana is 'Sun Aug 17'. I use Calendar.getInstance(TimeZone.getTimeZone("America/Indiana/Indianapolis")) to return a Calendar instance. I then call the getTime() method on that instance. It should return a Date object relating to that particular time zone. It will not. It defaults back to the server time. When I print out the Calendar instance everything is good, correct date, correct time,etc. WHY WON'T THE getTime() return the correct java.util.Date???
Following is the output was run today so the dates happened to be the same so focus on the Time. Output includes Server time, new Calendar values, and the Date returned by calendar instance getTime(). See that the Calendar is getting the correct Time.
SERVER DATE=Mon Aug 18 15:52:13 CEST 2003
CALENDAR INSTANCE=java.util.GregorianCalendar[time=1061214732975,areFieldsSet=true,areAllFieldsSet=true,lenient=true,zone=sun.util.calendar.ZoneInfo[id="America/Indiana/Indianapolis",offset=-18000000,dstSavings=0,useDaylight=false,transitions=35,lastRule=null],firstDayOfWeek=2,minimalDaysInFirstWeek=1,ERA=1,YEAR=2003,MONTH=7,WEEK_OF_YEAR=34,WEEK_OF_MONTH=4,DAY_OF_MONTH=18,DAY_OF_YEAR=230,DAY_OF_WEEK=2,DAY_OF_WEEK_IN_MONTH=3,AM_PM=0,HOUR=8,HOUR_OF_DAY=8,MINUTE=52,SECOND=12,MILLISECOND=975,ZONE_OFFSET=-18000000,DST_OFFSET=0]
Date from getTime()=Mon Aug 18 15:52:12 CEST 2003

I got it worked with using DateFormat.parse !
The trick is to instantiate a new Date object as a result
of parsing out of 'localized' date string.
with below code :
Calendar localCal = new GregorianCalendar(TimeZone.getTimeZone("America/Los_Angeles"));
localCal.set(Calendar.DATE, 25);
localCal.set(Calendar.MONTH, 7);
localCal.set(Calendar.YEAR, 2003);
localCal.set(Calendar.HOUR_OF_DAY,6);
localCal.set(Calendar.MINUTE, 38);
localCal.set(Calendar.SECOND, 11);
Calendar sinCal = new GregorianCalendar(TimeZone.getTimeZone("Asia/Singapore"));
sinCal.setTimeInMillis(localCal.getTimeInMillis());
int date = sinCal.get(Calendar.DATE);
int month = sinCal.get(Calendar.MONTH);
int year = sinCal.get(Calendar.YEAR);
int hour = sinCal.get(Calendar.HOUR_OF_DAY);
int min = sinCal.get(Calendar.MINUTE);
int sec = sinCal.get(Calendar.SECOND);
String sinTimeString = date + "/" + month + "/" + year + " " + hour + ":" + min + ":" + sec;
System.out.println("VIDSUtil.hostToLocalTime : time string now in SIN time : " + sinTimeString);
java.util.Date sinTime = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss").parse(sinTimeString);
System.out.println("time in SIN using Date.toString(): " + sinTime.toString());
It prints out :
VIDSUtil.hostToLocalTime : time string now in SIN time : 25/7/2003 21:38:11
time in SIN using Date.toString(): Fri Jul 25 21:38:11 PDT 2003
(Ignore the PDT, because Date.toString() defaults where the JVM is running)

I guess, this is because the RI client is not finding the
codec to ser/deser your Value Object. You need to register
the codec in the type mapping registry before you invoke
the web service method.
Here is a sample:
Service service = factory.createService( serviceName );
TypeMappingRegistry registry = service.getTypeMappingRegistry();
TypeMapping mapping = registry.getTypeMapping(
SOAPConstants.URI_NS_SOAP_ENCODING );
mapping.register( SOAPStruct.class,
new QName( "http://soapinterop.org/xsd", "SOAPStruct" ),
new SOAPStructCodec(),
new SOAPStructCodec() );
BTW, you can do the same exact thing on the client by using
WLS impl of JAX-RPC. Is there a reason for using RI on the
client side?

Thanks for your information, Yes, my client is Sun's JAX-RPC based, but the Server

Problem in Web service while return ICollection object

I developed a webservice, that need to be return a ICollection object.
while am doing this it showing an error that.
<b>You must implement a default accessor on System.Collections.ICollection because it inherits from ICollection.</b>
can u help me in this context
my code is like
ICollection iCollectionObj;
[WebMethod]
public ICollection GetResourceTypes()
DirSearchBO dirObj = new DirSearchBO();
iCollectionObj = dirObj.GetResouceTypes() as ICollection;
return iCollectionObj;
above code dirObj.GetResouceTypes() method return a collection that i explicitly converting to ICollection object and retuning....

Is your patching is still in progrees?If you are patching for basis components then you can expect dumps and they will not allow you to login to the system sometimes .In this case we can perform import from os level to get rid of the issue.
If your patching is in progress then I would prefer you to wait till it completes.And if this is happening after patching I request you to post log file entries.

Can FF win return mouse coordinates while over a .swf object

Hi there,
I have a flash object embedded in a page and need to get
coordinates returned from javascript to the flash object. I can get
this to happen in IE, Safari, and FF Mac even Camino. FF windows
will not return coordinates when the mouse is over the flash
object. Is there a way to do this? I'd really appreciate any info.
Thanks.
Is this a firefox issue or the way the flash player is
implemented into firefox windows?
Here is a link for clarity:

Thanks,
Beau

sorry for not using the code tags..just learn about it...thanx
my problem is.when i want to record every coordinates of the mouse while it moves..but using the printstream,it only records the end point of the mouse and not while the mouse moves/dragged.I'm developing a sketch pad program. the program needs to capture the coordinates and saved it into a file.i tried using it but keeps on saving the last point but not all
example
point A..........................point N............................point Z
i want the program to save the coordinate of point A,point B,C,D...point N....and last point Z
but it keeps on saving only point Z.can u help or give any ideas..thanx
