EXECUTE an external .exe-file (+Parameters) that creates data-files I want to use later in my servlet

[Patrick Kosiol <ko...@simu.de>]

Hi,

I'm runnung TomCat 4.0.4 and I want to start an external .exe-File.
My Code:

       String[] runString = {relativeDataPath + "data.exe",
         parameter0, parameter1, parameter2, parameter3};
       Process p = Runtime.getRuntime().exec(runString);
       System.out.println(runString);
       if(p.waitFor() == 0){
         ........

The 'data.exe'-File is placed in 
$CATALINA_HOME/webapps/ROOT/relativeDataPath so it should be no problem 
to access this File. The Number of  Parameters etc. is OK.
But I get the following Error-Message:

java.io.IOException: CreateProcess: 'relativeDataPath'/bfpldata.exe 
parameter0 parameter1 parameter2 parameter3 error=2

error=2 means imho that the File is not found. How can I execute my file 
to do that, what I want. Is it possible that the process can create 
files in the Tomcat folders?


Thx
Patrick

I think you'll need the full (absolute) path to the exe.  There is a call in
the servlet api to translate a relative path to an absolute path in the
server's file system but I can't remember what it is.
Otherwise, put data.exe somewhere on the system path and drop the relative
directory part.
