Hi All,

Can anybody please help me in knowing if the JBossCache is equally configurable and useful as GigaSpaces. How can we mention lease time in JBossCache and can we just keep objects in memory instead of persistence storage to database etc.?
Also how listeners/receivers work in JBossCache? I mean do they need to provide some template to cache for retrieving objects or it is simple key based.

Thanks.

Hi All,
I have a third party ocx that I'll be using in my java application. For that, I need to write a wrapper dll that I can load into my application through JNI. This dll will be interacting with the ocx and will help me call the methods in ocx and mapping the data types in Java to the ones in C.
My question is how can I generate a header file from the ocx file so that I can include that in the wrapper dll and call the methods defined in the ocx. This way I'll be implicitly loading the ocx into the wraper dll. Or is there any other way to load the ocx into my wrapper dll?
Thanks,
Isha

Yes, may be it won't be out of date soon, though not sure, but any updates on when Sun is gonna launch SCWCD 5.0?
Hi All,

I have read in FAQs for SCWCD regarding version 5 of the exam:

Quote from Bert on April 2006: "The [1.4] exam will be available and "current" for a long time. There is no plan to update the SCWCD exam, I would guess that the EARLIEST that the SCWCD will be updated is at least a year away. At that point, the current exam will still be available for AT LEAST another year past that."

And its almost one and a half year now.. Any updates on when Sun is going to release version 5?
If not now, then how beneficial will it be to go for 1.4?

Thanks,
Isha
Yes, thats very true. I need not restart the JBoss.
Anyhow, to make the script wait, I can use this:
sleep 10s
this will make the script wait for 10 secs where 's' is a suffix to indicate seconds.
Thanks.

Hi All,

I have written a shell script to update my web application, i.e. executing the shell script automatically stops the JBoss, replaces old ear file with new ear file and then start the JBoss.

I want the script to wait for the JBoss to stop and then start replacing the ear. I tried using wait $PID, extracting PID as:

PID=`ps -ef | grep 'jboss.sh' | tr -s " " | cut -d" " -f2`
PID=`echo $PID | cut -d" " -f1`

where jboss.sh is another script to stop the JBoss and then calling the wait as:

wait $PID

the issue with this is that it says:

test.sh: line 8: wait: pid 4215 is not a child of this shell.

Please help.
Thanks.

Hi all,
I am working on an application in which a user has provision to add pages from the internet and save them as bookmarks. Now I want the same to be done for intranet / local htm files as well. And If a file or page is behind a firewall - its title & handle to should be saved. On revisiting - we can assume that the access to the link is possible through the client - then it can be shown. Can anybody please suggest me, how this can be made feasible by using JavaScript.
Thanks,
