Hi frnd's ,

If we declare a instance variable (not static) in the init() method and initialize it with 0. Now we increment this variable in the service() method and displaying it.
If suppose one thousand request, invoke the service method. Will every request gets the value incremented by previous request or gets 1 only.

Hi frnds,
I am getting one error while deploying my proj in eclipse 3.1 which uses JDK 1.5. Following is the method :

public String toString() {
return new StringBuffer(thisClassName)
.append((getTaskStatus() == 0) ? " " : 7)
}

The error in Eclipse is :
Incompatible conditional operand types String and int

Though my projects is working fine and compiling successfully, it seems to be some Eclipse configuration is missing , can anybody help me out.


Regards,
Shishir
