Thanks Cory. Your book is now on my "to be read List".

Hi Cory,

Can you provide the performance metrics of any real world SOA application with and with out "Software Pipelines".

Would like to know the transaction throughput Vs response time scenarios as well.

Hi Jacob,

If you are just starting on the Webservices take a look at CXF as well.

All the best.

let me move it up a bit

I know that the NosuchObjectException comes only in two situations

1... When we want to get data from entity beans and there is no corresponding record in DB table.

2.... when client made a call to session bean which has been (session)timedOut already.


The first point doesn't fit to my application...,and so i am left out with the second.In the web.xml the session-timeout flag is set to 60(i.e;1 hour)...will it be the only tag i need to set or there are any other configurations to be done for this session timeout period.


Also if there are any other scenarios exist in which this exception might occur...kindly let me know.


Any help will be greatly appreciated.

Hi All

I have an enterprise application which is deployed on Weblogic server.I have Integrated IIS with weblogic server and am routing the requests from IIS server to weblogic app server.My problem there is thread in my application which behaves mysteriously when i access the application thru the IIS interface.The thread behavior is perfect when i use my application with out IIS,but i have to use IIS for routing the the requests.

Kindly let me know whether there is any known reason for behavioral mismatch of the threads with IIS and with out IIS.


Any help will be greatly appreciated
Thanks in advance

Java Forums - Extract tar.Z file through java

Hi Carol

I have tried this one earlier but the problem is that we need to use an external libraries such as Java Tar lib by TrustIce.I wonder why there no support for tar files in java.

Any way thanx for ur quick response.

If you have any other information abt this kindly let me know.

Thanx

Hello all

I am trying to extract a .tar file using java.
Can java.util.jar class can be used for this.

Once you've created the variable, you can add it to your project (Right Click --> Properties --> Java Build Path --> Add Variable). Not sure if this will help you access your text files thouugh.

Hi
i have tried adding it thru the Admin Console in the same way

Admin Console --> Environment --> Manage WebSphere Variables --> New

also restarted the server after adding the variable,but it doesn't
work

This is how am accessing the text files in my code.

this.getClass().getClassLoader().getResourceAsStream ("abc.txt");

hope this will give u a clear idea of my problem.

Note:I am not using WSAD

Hi all
Recently i have migrated from JBoss to Websphere5.1 and i am facing some problems in running my application that worked fine with the Jboss.
Problem is that i need to add something to the WebSphere's classpath and i was unable to do so .In Jboss i used do this by adding my application specific directory path to the JBOSS_CLASSPATH in the run.bat file and even in WEBLOGIC i was succeded to do so by adding the path to Welogic classpath in the startManagedWebLogic.bat.

Following will explain the problem clearly.

*I am placing some text files in some directory say APP_DIR.
and my application reads those files place in the directory.

*So to make available this directory to the application i used to add the
path of this directory say D:\APP_DIR to the app server's classpath.

*I was unable to do so in Websphere


Any help will be greatly appreciated.
