i have wriiten java code for client server communication - the client sends a digital signature and the server verifies it using the public key .I have sent the signature as a string from the client to server.although the verification comes as true most of the times , some times it comes as "false" .i dont know why it comes that way .

so my question is ::: is there any problem in sending the digital signature as a string....

mysql_fetch_arr ay is used to fetch the data stored in a database .i think you need the labels for the checkboxes to be fetched isnt it ? then you may do it using the above method .

i just want to create a simulation of LAN [ 3 clients ] using java. i got the code for the client and serversocket programs - although i could make connection between 3 clients and a server socket , iam not able to create a connection directly between 2 clients without the help of server socket .it will be great if you pls give me idea on how to create a simulation .
