Thanks Ankur for the pointer to the puzzle. Being in bench, it is an excellent timepass + little excercise for the mind.

Did anybody used any of the above caching systems in production environment?


I have evaluated the above products as well as EHCache.
AFAIK,JCS looks outdated and doesnt scale much.
OScache is suitable for web app caching of small java objects. But dont use this for disk caching.
SwarmCache performance is good and removes the objects from memory based on the algo. chosen. If memory is a constraint for u , go for this.
EHCache also is memory sensitive, but a bit slower than Swarmcache.
I also have a question to the list:
My application requires loading around 4M records into memory from database. We tried Caching products as well as in-memory databases. But,
the used memory keeps increasing and after a few days heap max. size is reached and the system hangs. Is there a product/approach that you would suggest for such a scenario.

Decided not to take the exam 'coz of the Sylvan Administrator's
cold response to my call in my city.
Thinking of complaining too.

Hi All
I searched the net and found the following contact details. I think that we need to call the nos. here.


Hi ...
Got my voucher after the regular 'blocked' and 'we are lagging' mails.
You should be calling the Prometric authorised centres in your city directly for exam scheduling. Eg. If you are in Chennai call Bitech and book your slot.
Fine.
Hey, I dont want to make too much fuss about it.(Dont need my 15 mins of fame )
Anyway, Just to enlighten Valentin:
https://coderanch.com/forums/
https://coderanch.com/t/157784/java-EJB-SCBCD/certification/Kathy-Book
https://coderanch.com/t/157632/java-EJB-SCBCD/certification/Kathy-book-SCBCD
The above topics contain a fairly open advertisement of the HeadFirst EJB book. So does Pradeeps thread on his article. Both of them help people preparing for the SCBCD, though it might be in varying degrees. Hope thats plain enough.
Retiring with that.

Hi,
I dont find any rational behind the double standard being followed by ranch.
Kathy and Bert bates write stories about their upcoming book. They can even find volunteers to help complete their book.(Ofcourse, I dont find anything wrong with it). But, some Pradeep can not invite people to give comments on an article he has written(thatz relevant too).
I am surprised to see this because, I have found that Javaranch is otherwise a really nice community.

I hope you find a community that is a better fit for you.


Hey,
This is not the forum to put this question sam.
Besides, Sun is not developing the EJB exam for developers in
India alone.

Hi all, i've developed an application. But when i make it a war file. some error appear. for example:
When i try to read a xml file from /WEB-INF/xml/ as follow, it cannot find it:
String dir=context.getRealPath("/");
String file=dir + "/WEB-INF/xml/res.xml";
and this code doesn't work. What should i do??

i appreciate if u can help u!



getRealPath() gives the path like this...
D:\tomcat4\webapps\examples\
remove the / in "/WEB-INF/xml/res.xml"
It should work.

Doesnt the option E look a bit awkward?
1 - D
2 - A,D,E
3 - C,G
4 - A
5 - A,E,G
6 - B,C,F,H,I
7 - C,F,G

Have a look at James
They have a Java API to let you write Java code to process emails that are called mailet API.
A mailet can generate an automatic reply, update a database, prevent spam, build a message archive, or whatever you can imagine

As far as I know, File system acess is denied to make sure that your J2EE application is portable across servers.
