No it doesn't. That's one of the main selling points of Java. When you get a reference to an object, you are actually getting a symbolic reference and not a direct one. So I am not sure if you can really access the memory like you can in C/C++.

This most often happens with a precompiled SQL statement and you pass the various variables at runtime. I have come across this error when i call a Java Prepared Statement and i haven't bound all the IN variables.
Try running 'policytool'(this utility ships with JDK, you can find it in the bin directory of your JDK installation), and set the required permissions. Also make sure that port 80 is not bound by any other program.

You can however put a Javascript check to limit the size of the textarea.

Yes find the jar file and add it to you classpath. The means to add depends on the OS.

For Windoze:

Right Click on My computer icon, and add it to the Environment Variable list. You could also do the following on your command line.

CLASSPATH=%CLASSPATH%;<path_to_j2ee.jar>

The above setting is however temporary and will be lost when you reboot.

For UNIX:

Set the following in your .profile file. CLASSPATH=$CLASSPATH;<path_toj2ee.jar>
or
do the following on your command line
set CLASSPATH=$CLASSPATH:<path_to_j2ee.jar>
export CLASSPATH

Be aware that the classpath delimiter for Windows is a semi-colon and the delimiter for Unix is a colon
Try using the Java SDK WinHelp, if you know the method name, it's a Walk in the park.

If you are talking about changing the icon outside the Java programming using Windows, right click on Jar file | Properties | Change Icon whould do the trick.

You could also make changes to the Windows Registry ( Achtung !!), but then it would change the icon for all the jar files on the system.

Hi Suja,

Reentrant means the thread of execution can leave the current object and re-enter at a later time in the execution timeline or 2 or more threads accessing the same instance concurrently

For example: Bean A calls Bean B which in turn calls Bean A, at this point Bean A should be defined as reentrant.

Try the EJB Specification for more info on this.

Hi Chuck,

Are you calling the 'create' method on the home object? Pls post the code to understand the problem better.
Hi,
I tried setting the page check seconds to 0 and 1, there is absolutely no difference between the two, none of them work. BEA says if you are using an exploded format of an EAR to have a file called REDEPLOY and touch it when u change something and everything gets redeployed. Tried this one too, DOESN'T work.
The page check works fine in a Single server configuration, if it has a Admin/Managed config it doesn't seem to work.
Any of you have had success to make the server recognise the changes to JSP's in a Admin/Managed server config, please let me know.
TIA.

Hi,
I am trying to implement message style web service and the text node under message returns null. The following is the setup.
I have a MDB waiting on a queue and i have a generated a web service on this queue. The standalone client looks up this web service to send a Document object. At the bean level i got a reference to the Element (which i presume is what is written to the queue by the weblogic provided servlet), when i try to get to the mesaage element level and then the text level i get the value as null.
Am i doing something wrong here, replies are much appreciated.
The setup:
jdk1.3.1
weblogic6.1

thanks,
Nitin

Which driver are you using?, It'd help if you post the complete error trace.
