To run a java program via a batch file,when called from a web server

Question

REM This batch file runs the Spider with the [-v] option.
REM Lines 51 through 54 are simple DOS commands..they call the Spider
REM The location of the Spider package is the important piece of information here...
REM a batch file has access to the whole computer where the server resides.
setlocal
set JDK=C:\j2sdk1.4.1_01
set PATH=%JDK%\bin;.;%PATH%
CLASSPATH=%JDK%\jre\lib\*.jar;.;%JDK%\jre\lib\ext\*.jar;.;%CLASSPATH%
java spiderpackage.EntryPoint -v
endlocal
I am trying to run this batch file from my web server.I can see nothing on my browser.I can run the same program from my machine but unable to run from web server.what should I do?

Answer 1

I am making my question more clear...
I have a Windows batch (*.bat) file that echoes some html, then calls a java program the output of which is html as well, then echoes the final html.
To make sure that the java program gets properly executed, I set the necessary environment variables (e.g., JDK, PATH, CLASSPATH, etc.). The script looks something like this:
setlocal
set JDK=path_to_JDK
set PATH=path_to_java
set CLASSPATH=path_to_java_classes
echo ^<html^>^<body^>
call java foo
echo ^</body^>^</html^>
endlocal
The idea, of course, is to call this script through a browser, on a web server.
Curiously, both echo lines return to the browser just fine, but any output from
the java program (which just writes html to STDOUT) does not make it back.
Can someone explain to me why this is happening? How do I set things up so that the output (STDOUT and STDERROR) from the java program make it back to the browser?
