Runtime.getRuntime().exec(cmd) not working

Question

I have created binary scrip to parse file from one format to another format and the file parser is available on Linux path and working fine when calling from command prompt but while calling this program from jsf or any any java form bean it adds some special charaters with program and throws IOException as belows
calling command
String[]     cmd={"delimiter",inputFile.toString(),outputFile.toString()};
Process     p=Runtime.getRuntime().exec(cmd);
it gives following error.
java.io.IOException: delimiter@! : not found
while calling this from jaav main application working fine.
any suggestion would be appriciated.

Thanks.
I printed out whatever values are being passed and it is printing the right values on console and in log file and I also tried this command in stand alone application program an working fine. but when I call it from jsf form bean it adds ^@ at the end of first parameter and says ;
IOException : delimiter^@ : not found
i actually created the same copy as delimiter^@ and put it in same path directory with 777 mode.
and now its working fine. but I did not know the reason why it change the name of first argument.
Thanks,
