+1 to both of those.
This code seems a bit strange, what is it intended to achieve?
String line = null;
Object object = null;
while ((line = dis.readLine()) != null) {
ObjectInputStream ois = new ObjectInputStream(dis);
object = ois.readObject();
ois.close();
}
return object;
The DataInputStream.readLine() method is deprecated since Java1.1, seems
a bit odd to use that too...

RE: Stream closed IO Exception when using Tomcat 5.5.28
Thanks Pid.
The line number specified in the exception matches with the below line of
readObject function.
while ((line = dis.readLine()) != null) {
The connection is not getting closed at the other end.
Connector config from server.xml is as follows.
Let me know if any other information is required.
Thanks and Regards,
Prathima.

Does the full stack trace for the exception below show a line number which
matches the class above, and if so, which line is it?
Is it possible that the connection is being closed at the other end?
Can you also post your Connector config from server.xml?

RE: Stream closed IO Exception when using Tomcat 5.5.28
Thanks Pid.
It is happening in both Windows 2003 and Solaris SPARC.
Under normal usage only exception is thrown.
Yes, All the jsp's are recompiled for 5.5.28.
DataInputStream is extracted from the HttpServletRequest req.
DataInputStream dis = new DataInputStream(req.getInputStream());
Object request = readObject(dis);
private Object readObject(DataInputStream dis) throws Exception {
String line = null;
Object object = null;
while ((line = dis.readLine()) != null) {
ObjectInputStream ois = new ObjectInputStream(dis);
object = ois.readObject();
ois.close();
}
return object;
}
Let me know if any other information is required.
Thanks and Regards,
Prathima.

When does this occur, under load testing or under normal usage?
Does it happen during specific request types?
Does your app have compiled JSPs and if so, have you recompiled it for
5.5.28?
> Does this fall under any known issues in 5.5.28 version?
None that I'm aware of, but then the above information is quite limited.
