Hi, guys:
I am a new comer to this mail list and I am a beginner
for java. I try to set up java web server several
times, but I failed each time. When I type "start
httpd" and run it, another dos window pop up, and then
close very quickly. In that window, it looks like
this:
Usage: jre [-options] classname [arguments]
options:
-----
Program c:\javawebserver2.0\bin...\jre\bin\jre.exe
exited with code 1
c:\javawebserver2.0\bin...\jre\bin\jserv.exe
c:\javawebserver2.0\bin...\jre\bin\jre.exe
jserv: shutting down the server
Is there any one can help me. really appreciate your
help.
