Irregular delay while running a dos batch file using a servlet class

Question

i used RunTime( ) class to execute a dos-batch file containing some commands like changing the directory, running an exe(executable.exe) file...etc in a servlet class. while this servlet class is invoked, the exe file(executable.exe) is run after irregular delay at different trials.
Note: When this batch file is run in a stand alone java class, it is working fine.
what can be the possible cause of this prob? Help me in this.

Answer 1

It's ok - I've found the answer.
I'll post it here for anyone else who is interested.
The problem stemmed from the fact that I had to put the path to javaw.exe in quotes, as the batch file is dynamically generated from the user's environment, and then run. The user's system properties gives a path to java home using a full path name, which WinNT/Win2K doesn't like.
The following batch file content solves it, closing the DOS box after starting javaw.exe. Before this part of my batch file, there is just some file copying that goes on for the autoupdate process.
set PATH=%PATH%;"D:\Program Files\JavaSoft\JRE\1.3.1\bin"
start /B javaw.exe -Dmyapp.home=C:\myapp myapp.client.MyAppClient subSys
exit
The parameter subSys is just a command line parameter that MyApp.java looks for, so not relevant for everyone.
/B prevents a second DOS box from opening.
exit simply closes the DOS box once the javaw.exe process has started.
Too easy! Although I can't believe how difficult it was to find information about this. Hopefully it will be of benefit to others.
