Hi. i'm running under solaris 10 ... and i have this problem:

running an external aplication from command line in s.o works fine and
no cpu consume.
running from java with runtime.exec the same sh it eats my 85% of cpu

Runtime rt = Runtime.getRuntime();
    try {
        Process proc = rt.exec("/opt/ANTHaxfov42/bin/XSLCmd -i /opt/
ANTHaxfov42/etc/XfoSettings.xml -d "+ full_xml_file + " -s " +
full_xsl_file + " -o " + full_pdf_file + " -silent");
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

any ideas ?

tks !!!!!

What happens to the output in both cases?

Hi

I'm having the same kind of problem with:

Process server = Runtime.getRuntime().exec(exeCommand);

"execCommand" is the full path to an .exe file. This takes up to a
minute to load from Java and but the same program runs instantaneously
from the command line. Also CPU utilization is high.

The same Java application is running on many different machines and
the slowdown is only occurring on a few of them. So something is PC
specific but we can't isolate. The PC had 2 gig of memory is a P4 3.07
Gigs.

I wonder if there a different, more efficient Java class to load an
exe?

Anyway, any ideas are more than welcome.

Thanks

Elliot

Perhaps there's something inefficient in whatever you're using to read the
output and error streams. What are you using for that? (Generally
speaking, not reading them is not optional)
