Hai,
I am new java developer. Now i am doing one struts application.
In my application, at the User registration time, i need to Encrypt the password field and then i like to store into the database.
After that the same user will be logging, at the moment the database password will decrypt and it will be compare to the User entering password.
If both password's are equal, then only the User will allow the logging.
can anybody know or have any sample code for Encrypt and Decrypt.
If yes, kindly post me, my mail id is .
I am expecting anyone's reply.
Thanks

J2EE Heap size limit on Windows
We are using J2EE Web server on Windows OS. The sizing tool for our product recommends using RAM of about 12 GB.
But, we found that J2EE web servers will be haivng a limit of 1.5 GB heap size, making the remaining 10 GB of RAM useless.
Is there any way to overcome this problem?
Thanks in advance,

I have a class in which i have a function that calls another 3 classes.
Each class returns a value to this function. Now i want to display these 3 values in 3 different columns in a XML document. How do i return these 3 values or send these 3 values seperately(say in different hashmaps). (0) |

Hi,
I am using rmi's in my program and i met with the following error::
Whenever i do the remote method invocation,the client rather than looking up or searching at the server whose IP address
is specified,ends up searching at loopback(i.e at IP address 127.0.0.1).when the command say
comp = (RemoteCommand)Naming.lookup(***)
is invoked...
I tried printing out the contents of the variable "comp" here and it is as follows::
Proxy[RemoteCommand,RemoteObjectInvocationHandler[UnicastRef [liveRef: [endpoint:[127.0.0.1:45832]..
I tried executing the client side with the following explicit declaration of the server IP address::
java -Djava.security.policy=server.policy -Djava.rmi.server.hostname=172.23.1.145 Engine
But still i faced the same problem..
However,when both the client and server are executed on the same system,the program works fine..

say its a server that launches threads upon connection.
public static int connCount;
which is incremented or decremented in the constructor / deconstructor of the thread class that launches .
public Class Run{
public Class serv{
public static int connCount;
Serv(){
connCount++;
}
-Serv(){
connCount--;
}
}
public static void main(String Args[]){
//bla bla bla
// to launch we instantiate serverSocket and wait for connection
// then on connection, logic
if (serv.connCount > 50){
// Deny because of Max users
}
else{
// Carry on
}
}
}
i hope that helps, my java is a tad rusty, and i'm not sure about the sign in front of the deconstructor. preferably you'd use static class method to access connCount.
Make sure you understand what static means. (0) |

if its a multithreaded app, you can use a static counter and run a logic statement before launching a new thread on user connect, much like FTP servers do.

| all of this class and method crap isn't necessary.....if you only need to do a simple program, then just write one for loop with a nested if statement, that way it won't be so damn complex! (0) |
