Using NetRexx on OpenIndiana

[Jason Martin]

I have found that running:

nrc some_file.nrx
-or-
NetRexxC.sh some_file.nrx
-or-
java org.netrexx.process.NetRexxC some_file.nrx

Really, really slow......................

Running java -jar is not slow.

Here is a script adapted from jedit:

#!/bin/sh
#
# Run a NetRexx jar file.
#

# Find a java installation.
if [ -z "${JAVA_HOME}" ]; then
    echo 'Warning: $JAVA_HOME environment variable not set! Consider setting it.'
    echo '         Attempting to locate java...'
    j=`which java 2>/dev/null`
    if [ -z "$j" ]; then
        echo "Failed to locate the java virtual machine! Bailing..."
        exit 1
    else
        echo "Found a virtual machine at: $j..."
        JAVA="$j"
    fi
else
    JAVA="${JAVA_HOME}/bin/java"
fi

# Launch application.
# Set path to your own NetRexxC.jar or NetRexxF.jar jar file
exec "${JAVA}" -jar "/export/home/agrellum/NetRexx-3.05GA/lib/NetRexxF.jar" "$@"

This might all be dependent on classpath. One way to make NetRexx really slow it to have it run from a directory that has many java classes in zips and jars in directories below it; these will all be scanned. Java -jar will disregard the set classpath if I am not mistaken.

I don’t have scripts but I set a shell alias for java org.netrexx.process.NetRexxC. Locating Java once should be enough until you change things.

best regards,

René.

Thanks René,

I had a period in the classpath.
export CLASSPATH=$CLASSPATH:.:$HOME/NetRexx-3.05GA/lib/NetRexxF.jar

It was looking through 42.9G of data.

Spent weeks trying to speed things up.

Maybe a mention in the manual would help someone who might do the same in the future.
