Hi all!

Is there anyone out there who knows how you run a .bat file from an IS flow. I dont mind to code if thats neccasery.
The task is to make a flow that runs a .bat file that maps a server when its called.

Thanks.

Try writing a java service with the following code:

try{
Runtime.getRuntime().exec(“batchFileName.bat”);
}catch(Exception e){}

Thanks for your answers!

I tryed the first example but I get a strange error.
C:\IntegrationServer4\webMethods\IntegrationServer4\packages\Utils\code\source\runBatFile.java:36: illegal escape character
Runtime.getRuntime().exec(“c:\map.bat”);
^
1 error
(The ^ sign is under the ; character)

Do you have a qlue of what this means

Use / instead of ; or, even better, use java.io.File.separator

Correct it as below:

Runtime.getRuntime().exec(“c:\\map.bat”);

(Note the two backward slashes.)

But it is better to create the string using File.separator so that your code will be portable across different operating systems.

Runtime.getRuntime().exec(“c:” + java.io.File.separator + “map.bat”);

Hi all!

I got it to work with

try{
Runtime.getRuntime().exec(“batchFileName.bat”);
}catch(Exception e){}

Thanks for all answers.

Michael,
Your Java service would be more robust if it waited for the background process to finish and ensured that an int code of 0 was returned.
You current java service will act the same way, regardless of whether or not your .bat file executed successfully.

You can use fireCommandExec service found in WmSamples package. First call pub.string:messageFormat service and pass the value to pattern in serciceIn as “yourBatchfile.bat {0}” where 0 is the argument you want to pass. You can pass more than one argument by adding {1}, {2} as so forth. Then call fireCommandExec service and pass the final value to fullCommand you got from messageFormat.
