On OS X, JBoss4.0.2, mySQL:

I have an EAR file that I build using and ANT script, then manually copy into my jboss/server/default/deploy directory. I have an environment variable that I normally will set with a bash script. However, I am starting/stopping this in development using the myEclipse JBoss 4 icon. I am trying to find where to set this property so that it gets read when JBoss. I have tried setting it as a JBoss Launch configuration, but it doesn’t stick. When I go back to check on it, its gone and the application can’t find the value either.

What is the best way to set this so my application sees it?

When you say an environment variable, do you mean something like:

export SOME_VAR=/usr/local/lib

or do you mean a Java system variable that you can get with something like:

String property = System.getProperty("SOME_VAR");

Sorry, I should have explained better.

Here is my *partial* script that sets the variable before starting JBoss in production:
JBOSS_HOME=${PROJECT_BASEDIR}
PROJECT_PROPERTY_FILE=${PROJECT_BASEDIR}/properties/project.properties
…
export PROJECT_PROPERTY_FILE

According the propertary class notes, this is coupled to the environment.

And here is how it is used in the code:
private static final String PROPERTY_FILE_KEY = “project.property.file”;
String filename = System.getProperty(PROPERTY_FILE_KEY);
…
BufferedInputStream bis = new BufferedInputStream(new FileInputStream(filename));
// load the project properties into the new properties object
_nprops.load(bis); <== proprietary class I don’t have source for
_nprops.putAll(System.getProperties());

So I can either try to rewrite existing functionality with my own sort of map, or I can set the property environment variable so Eclipse picks it up. Like I said, this works already in production, but in trying to run it inside of MyEclipse I can’t seem to set this.

Ahh, System.getProperty will pull any properties set with the -D command line argument, you can set that in the JDK preference panel under Optional Arguments, something like this:

-DsomeProperty=SomeValue

then you can get it with:
System.getProperty(“someProperty”);

Thank you, I should have known it was there, I figured it changed because it was an IDE. I added the “-D” arguments to the Window|Preferences|Java|JDK and that did the trick!

Very cool, glad it did the trick.
