hi folks,
I am preparing for SCWCD and am planning to clear it before this month end. I didn't know we can specify these many tags in web.xml. Its truly difficult to remember all those tags. Is the order of the tags also important? Hope someone would send me those PPTs u guys mention to me too.

hi guys,
I dont know C or C++, so I am trying to find a jni wrapper. I found JNIWrapper, Xfunction and Jwindows but JNIWrapper and Xfunction are commercial products and JWindows is no longer supported. What I need is an opensource jniwrapper api. I searched up and down on the net but no use. Maybe I have missed some pages so if anyoone of u know where i can find it, please provide it to me.

I am using Java 1.4, J2ee 1.3.1 and Ant 1.3
My env. settings are like this


When I am trying to build J2EE example 'Converter' by issuing the command,
ant -verbose converter

I am getting the following error regarding NTVDM.exe,
A message box appeared with title
"16 bit MS-DOS subsystem"
and message is

<Drive>\windows\system 32\ntvdm.exe
Error while setting up environment for the application. Choose 'close'
to terminate the application

Also the error on the DOS window is ,
"Property ${myenv.J2EE_HOME} has not been set"

While the ant is running I am getting the "ntvdm.exe" error message, when "Init" part of the "build.xml" is started.

I am not understanding the relation between the two, as I have correctly set my environment paths. Please help.

Whatever the reason may be, having those certs are always rewarding

I have searched for the Oracle Forms tutorials in google groups and also in Yahoo groups and I am not satisfied with the results.

But I am still trying.

I vote for
Sun certified programmer, by Kathy Sierra, Bert Bates
After reading the book i felt confident that I will pass the exam. and I got 86%.
It is a great book. Also 'Head First Java' is a great book for beginners. I haven't read that but I have browsed through it once.

Yesterday I passed SCJP with 86%. Should have got more but its ok. I am Happy.
I have done written lot of mock exams and gradually improved from 50 something to 79% just before exam day.
I would like to thank Kathy and Bert for their excellent book and Dan for providing a lot of questions for the test takers to practice on. I would also like to thank all the team of JavaRanch because it is the nicest site for all the Java lovers.
luv ya all and thanks

An article on Bit wise operators, especially shift operators, would be good.
They generally do take lot of time in the exam.
Tips on how to find out the correct answer with out need to converting to binary and again back to decimal are very much needed.

thanks in advance
