Hi Guys,

I'm working on online payment system and I'm looking for a performant method to implement in order to send payment transactions to the Bank server

- Put transactions in JMS QUEUE and let an MDB Bean sends these transactions to the Bank server OR
- Create a thread pool for that purpose OR
- What to do in other cases ?

Please let me know what to do in order to achieve speed end performance

Thank you

For security purpose i would insure that no one can read confidential information from the heap dump. We send the cores after crash to external teams to be analyzed.
Can the heap dump or javacore save information such as JMS queue messages, Log messages and other? As i know the cores stocks only information about memory!

Thank you for your help
Hi,


Please, is there any way to read the Queue JMS messages from a heapdump or javacore generated after server crash?

Thank you.

Hi there,

I have read a bug from that site http://opensource.atlassian.com/projects/hibernate/browse/HHH-2470 for the hibernate version 3.1.3. Is that means that all the prior versions to 3.1.3 are also affected by this bug.

Think you in advance
I have tested the application in WLS9.2 and seems to work well!!! So, we have installed the application in WLS9.2.

Yes, i have set the timeout-secs to 10 minutes in weblogic.xml (<session-descriptor> <timeout-secs>600</timeout-secs>) and set session-timeout to 600 in web.xml. This doesn't solves the probleme!

Hi,

I have developed an application of two struts Action servlets and one HTML Form. I set an attribute session in servlet1. The servlet1 waits for 2minutes before forwarding (mapping.findForward) to the HTML Form wich in turn waits for 5 seconds before calling the servlet2. The probleme is that i can't get in the servlet2 the session attribute setted in servlet1. The application runs correctly in Tomcat but not in Weblogic (i use weblogic9.1).

It seems that the session is lost between servlet1 and servlet2, what could be the probleme in weblogic especially when it runs correctly in tomcat?
I have setted the <timeout-secs>600</timeout-secs> and then removed this attribute and the probleme is the same

Thank you in advance for your help.

Hi everybody,

My web application uses the struts workflow extension from livingLogic "http://www.livinglogic.de/Struts/"; to manage the workflow and so the application experiences many stackOverflowError. I don't know if theses errors can be caused by this framework?
Another question is that this framework is not updated since august 2003, is that means that is not yet used?

Thank you for your assistance.

Hi everybody,

I'm a newbe to maven and i'm looking for an updated online maven2 repository as the standard central repository "http://repo1.maven.org/maven2/"; is not yet updated. Is it recommanded to create my own repository from the central repository and update it with the latest releases of third-tier packages (struts, spring, ...)?

Thank you

Hello!

What could be the major consequences of desabling HttpSession replication in Weblogic.
Can this reduce overhead and increase performance in the application runing over weblogic?

Thank you for your help

I will unescape in the server side; i think it's good solution.

for security reasons we can't do that.

The apostrophe is coded in the database with corresponding ascii code for security purpose. So, the escape caracter don't resolve the probleme!
