Telnet invocation via Java code using apache commons net jar

All,

Please let me know how do I inovke Telnet prompt via Java code using apache commons net jar .

I have done the following code

String command = "cmd /c start cmd.exe /K \"telnet <ip-address> \"";
Process process = Runtime.getRuntime().exec(command);

It works fine for 64 bit JRE with 64 bit Telnet client(Win 7 64 bit OS)

But it fails while i use 32 bit jre..

How do i achieve the 364 bit telnet client via 32 bit JRE

I read in the posts it can be done using Apache commons class..

What does Runtime.getRuntime().exec have to do with apache commons net?

All,

Please any one have the idea about invoking the Win 7 64 bit telnet client via Java Runtime.exec(). on 32 bit JRE

String command = "cmd /c start cmd.exe /K \"telnet 10.78.241.20\"";

` Process proc = Runtime.getRuntime().exec(command);

It throws "telnet' is not recognized as an internal or external command, operable program or batch file."

But in case if the same above statements run on 64 bit JRE it works fine.

Kindly light up me on this

Thnks

Start by using Runtime.exec(String[]) instead of Runtime.exec(String). If that doesn't help, read through this article and follow all its advice.

String[] cmd = {"cmd.exe", "/start","\"telnet","10.78.241.20\""};

Process proc = Runtime.getRuntime().exec(cmd);

It's not working

You've done all this:

this article and follow all its advice.

?

If so, post your complete code.

At last, found the solution by someway.

Copy the "telnet.exe" file from C:\Windows\System32 folder to C:\Windows\SysWOW64

Post this operation, telnet prompt got opened while it executed via 32 bit JRE even though telnet client is specific to operation system. i.e 64 bit.

String command = "cmd /c start cmd.exe /K \"telnet <ip-address> \"";
Runtime.getRuntime().exec(command);
