Hi All,
Say i have a class A with 10 methods in a class.
and one of the methods being
public void doWork(){
System.out.println("test"};
}
i have another class B in which i have created an object of the A class .
now in the main method of class B i take an argument "doWork" which is a string (obvioulsy)
is it possible for me to call the methods on the class A based on the string variable which is going to be exactly the name of the method .??
how do i do this ..
hey i dont want to use any if or any other conditional blocks ..
something like
//String s = "doWork"
//s"();"
Thanks Guys ..
Sunil

Hello Mahesh ,
Thanks for the reply .. its not an oracle error .. i checked the code and i realised the connection was not closed properly .. i had made a silly error .
Thanks,
Sunil

Hello Tim ,
Thanks man .. that helped .. i'll try the connection pooling today .. but i have a doubt but its back to fundamentals ..
in a class say we have a constructor which has a static variable .. now i use the ++ operator to keep track ofhow many instances of the class are being created .. right ..
now i tried this same thing with ejb to see how many instances are being created of the bean .. and the count increases even if i am instanciating the bean with the same PK ...so how do i know if the instance is same or diffrent ..
Thanks,
Sunil
ps .. thanks for your reply

Hi everyone ,
i have a problem with entity bean .. i am using BMP ...
when a client invokes the entity bean the instance is created ..
it establishes connection with database (i have utility method that establishes connection .. getConnection()).. for the method calls .. but these connection are not getting closed (when i write conn.close().. it does not throw an error too ..!!)i am closing the connection in the finally block of each method....
once the program has made around 150 calls .. oracle throws an error "excceding 150 process " (so i asumed that connection is not being closed)
how do i do connection pooling .. i thought this was handled by the container ..i am using J2ee refence server ..
another doubt ..
say i have 150 records(rows) in the table ... diffrent clients need to access these rows ... now when one client invokes a findByPrimarykey(DataPK dpk) on the entity bean ..
and if another client needs to access the same data ... so can i have the client to access the same instance created by the first time rather than the client creating a new instance ..
because in the kind of application i am working on many clients need to access the same data ...
and this data gets refreshed / updated by another client altogether ..
some thing like the Stock Quotes .. where many clients access the stock quote .. but at a time stamp the data is getting updated in the database ..
can any one help what approch i should take towards this ...
Thanks,
Sunil
