the basics of sockets
Open a socket.
Open an input stream and output stream to the socket.
Read from and write to the stream according to the server's protocol.
Close the streams.
Close the socket
Server
StartServer àcreate new memberDataObject
Initialize static strings
memberDataObject.connect ()à do the following
read from file properties and assign values to static strings.
new ConManager (sql_url, sql_userName, sql_password) create
sql_url = "jdbc:microsoft:sqlserver:// sds-2003:1433;DatabaseName= CHILD_help";
sql_userName=sa;
sql_password=sa;
ConManager.makeConnectionPool ();à create pool of 10 connection, closed
ConManager.getConnection ();à take url, username, password, return opened connection
Parse acdconfig=D:\\TeleContact\\Server\\config\\ACDConfig.xml using saxparse
Add the content of file in array list.
check in debugLevel àconsole or log
StartServerà create new AbstractServer(Integer.parseInt(memberDataObject.port.trim()), 100,
"com.RequestHandelerClass",mberDataObject.maxQueueLength,
memberDataObject.maxThreads, memberDataObject.maxThreads)
AbstractServer extends Thread
Constructor do :
1)
port=1984
backlog=100 The number of requests to backlog if threads are busy
requestHandlerClassName= com.RequestHandelerClass
maxQueueLength=20
minThreads=20
maxThreads=20
(2
Create new RequestQueue(requestHandlerClassName,maxQueueLength, minThreads, maxThreads)
Create the minimum number of threads and but them(Threads) in List/pool
The thread pool that is servicing this request
// so till now for the server run 20 threads started in the background to handle the client requests
AbstractServer.startServer()
Create our Server Socket and start our Thread
In run()
Make socket Accept the next connection
// Listens for a connection to be made to this socket and accepts it. The method blocks until // a connection is made.
// Log some debugging information
// Add the socket to the RequestQueue (add it to linked list/end of queue thread)
Adds a new object to the end of the queue
See if we have an available thread (from the 20 thread running) to process the request
Yes->notify thread(wake up) invoke run() RequestThread
On run()->
Handle the request
this.requestHandler.handleRequest(socket);
AbstractServer->Abstract super class for creating servers
RequestQueue->accepts new requests and processes them with its associated thread pool
RequestThread->extends Thread / handles incoming requests
agent -->implements Serializable / bean id,name,ext,password,type,user
data -->implements Serializable / bean code,command,result
RequestHandelerClass-> handel requests from client
it's instance fields initialized from memberDataObject class that originally loaded from the property file
then get data from objectInputStream from socket then get data.getCode()
and switchcase 1,2,4:
int updateDatabase(sql),set send data fields
case 3:
ArrayList<bean> select(sql)
Set send instance fields

Set send instance fields
Case 6:
Check if file needed to delete is exist or not
Set send instance fields
Case 7:
Check if file exist or not, and if exist check if there are available memory to copy file if yes->
