converting a batch file to shell script (multiple jars on Mac)

Question

My shell scripting knowledge is minimal. So I'm trying to convert the following:

@set CLASSPATH=".;.\resources\;.\lib\jboss-client.jar;.\lib\jfxtras-labs-2.2-  r4.jar;.\lib\jfxrt.jar;.\lib\icecile.jar;"

echo CLASSPATH: %CLASSPATH%
".\jre7\bin\java" -classpath %CLASSPATH% com.ent.thing.icecile.ui.icecile

so this is what I wrote

#!/bin/sh

export CLASSPATH=/resources:/lib/jboss-client.jar:/lib/jfxtras-labs-2-r4.jar:/lib/jfxrt.jar:/lib/icecile.jar

echo CLASSPATH: $CLASSPATH
"java" -classpath $CLASSPATH com.ent.thing.icecile.ui.icecile

Im using a Mac computer and I've been glossing over some documentation but this doesn't want to run for me. Any help would be great

Cannot find main class. Does this structurally look correct? — Joshhw

The first thing I can see wrong with your script is that, you're using absolute paths in your classpath. While this is not wrong, I doubt it is what you want. So, using relative paths (./) instead of absolute path (/), should solve one of your problems.

Try:

#!/bin/sh

# You don't need to 'export' unless you want the variable to exist
# outside of your script
CLASSPATH=".:./resources:./lib/jboss-client.jar:./lib/jfxtras-labs-2-r4.jar:./lib/jfxrt.jar:./lib/icecile.jar"

echo CLASSPATH:$CLASSPATH
java -classpath $CLASSPATH com.ent.thing.icecile.ui.icecile

this did the trick for me. Could you possibly tell me what the echo CLASSPATH:$CLASSPATH actually does? I had to transfer this but my scripting skills are beginner level.

@Joshhw - it displays the word CLASSPATH, followed by a colon, followed by the contents of the variable $CLASSPATH.

echo in shell is just like echo in batch scripts or print in other languages, and it's mostly used so the programmer can see what is going on. That line is basically saying, print out the literal CLASSPATH: followed by the value in my CLASSPATH variable
