I launch an executable program from a servlet with

Process proc = Runtime.getRuntime().exec("d:\\servlets\test.exe")

This exe use some dll to access a SYBASE database
(d:\Sybase\dll\...) and when i try the servlet, i get a message on the server:

the dll libcs.dll can not be found in the specified path
d:\servlets\;.;c:\winnt\system32;c:\winnt\system;c:\winnt;c:\winnt;c:\winnt\system32;

and test.exe is not executed.

There is no probleme when i launch test.exe in MS-DOS (or by double-clicking on it) or when i put test.exe in d:\sybase\dll and then try to lauch it with the servlet
but it should not stay in this directory.

d:\Sybase\dll\ is in my PATH

can somebody help me please ?

Laurent.

The Sybase dll is not in the path used by the servlet:
d:\servlets\;.;c:\winnt\system32;c:\winnt\system;c:\winnt;c:\winnt;c:\winnt\system32;

Either add d:/sybase/dll to the path used by your servlet container, or pass a suitable environment via the exec call.

Give the path "d:\sybase" in the environment path, that's the least you can do.
