How to integrate command prompt in an client server application?
Command prompt integration consists of
2 parts; Telnet Client in Web and on server system it uses Microsoft Telnet
Service.
Telnet Client allows a computer to
connect to a remote Telnet server. Telnet Client can be developed in Java Applet
which connects to build in Microsoft Telnet Service.
On Windows, each Telnet command prompt
session consists of two processes: TlntSess.exe and Cmd.exe. TlntSess.exe is
responsible for managing the Telnet session. Cmd.exe is the command
interpreter, or shell program, that runs commands, programs, or scripts on the
host
Challenges/
Problems
- The Microsoft Telnet Service which is running on the server system user may have security concerns. Also it was separate service running on the server.
- On client side, updating the Java version with new on client side was blocking applets from run.
Solution
Hence, You replaced the Microsoft Telnet
server with the KPYM server and integrated
the server module in application, so that the telnet server is running under
the same process and running separate service on the server was no more
required.
Also you will need to provided the signed JAR applets by adding
the Trusted information inside the Metadata file to avoid the security error
message coming with after Java version update.
How to integrate File Manager in an client server application?
File Manager allows to transfer the
files from Local to server system and Vice-versa. The User can access this
functionality similar to the Windows
Explorer. He/she can do Copy, Paste, delete, drag-drop with single/multiple
files and folders.
It has 2 components :
1] Web Client to show file List on client side as
well as file system from remote system
2] Server component running on server system
Challenges/
Problems
Application is hosted on IIS Express; IIS Express do not
support the FTP where as IIS has support for FTP.
We can use the ActiveX control which runs only on IE, for
Firefox, we have to use the java Applet which increase the code duplication.
Solution
You can overcome the challenge by implementing the File Manager server and client components. Use FTP / HTTP protocol to transfer file from
server to client and vice-versa.
This technology support to get client side file
explorer using java applet and can transfer files using FTP protocol. Server
side component can be developed using .net technology. Client side component can be developed using java applet so that it will supports Internet Explorer, Firefox
and Chrome browser as well.
