Subject RE: problem with the java needed urgent
Date Fri, 05 Sep 2003 11:57:05 GMT

 Ok I think now I have got the problem, not sure though. When I run the target "run" in verbose
mode I have got the output which is very long. I was trying to execute that on the command
line but it is not taking more than 2046 characters. I think this is what I have heard about
too long command line problem in windows. 

1. How can I overcome this problem of too long command line. 
2. The command line output I got was java -Dparameter= value -cp classpath etc... though in
my ant build script file I have given first classpath and then -Dparameters which is required
to directly execute at the command line. Anyway I will change the order of that once too long
command line is solved.
3.Complete build sequence order is misleading. I have 5 targets in total called clean, init,
compile1, rmic and run.
  I have this dependcies
  target rmic depends compile1 
  target compile1 depends init
  target init depends clean

  and then a separate target run.
  It's saying the complete build sequence is [run, clean, init, compile1, rmic]. I think rather
it should say [run, rmic, compile1, init, clean ]. Any comments ??

Thanks ..

It sounds like it's crashed with no output but the forked JVM hasn't
terminated - ANT will wait to join up with any forked JVM. Don't be fooled
into thinking that ANT will spawn another long-lived JVM and then the ANT
JVM will exit.

Have you tried running in verbose and then executing the command that output
directly, just to ensure the the command line is OK - that way you can
determine whether ANT is the problem or the launched app is.

And finally, the line

value="-Djava.naming.provider.url=t3:// -Xmaxf0.10 -Xms32m

will set the system property java.naming.provider.url to be
"t3:// -Xmaxf0.10 -Xms32m -Xmx256m", which may be what's
going wrong.

Either split each jvmarg up or use:

line="-Djava.naming.provider.url=t3:// -Xmaxf0.10 -Xms32m

Hi friends,

 <target name="run" description="runs the application">
          <java classname=""
                <arg value="-pdd ..\conf\oclient_pdd_vc.xml"/>
                <jvmarg value="-Dplatypus.trampoline=false"/>
                <jvmarg value="-Duser.region=GB"/>
                <jvmarg value="-Duser.language=en"/>
value="-Djava.naming.provider.url=t3:// -Xmaxf0.10 -Xms32m
                <jvmarg value="-DPlatformHost.IP=localhost"/>
                <jvmarg value="-Dflexlm.licensefile=..\conf\lmdlicmx.dat"/>

When I run the above target, it goes into executing mode saying "executing
task "run" " and never returns and even sometimes I couldn't cancel it
though I can work with other applications. I am unable to point out what's
the problem is ??. I am just transferring my IDEA environment to a ant build
script file. Though I am running it in verbous mode .. At least I want to
know what's wrong ? How can I debug this situation ?? or is something wrong
with this target ??

Thanks in advance..
