RE: Configuring System properties
Howdy, If you want to go the same route, simply add -Dsearcher.home=... to the JAVA_OPTS variable in $CATALINA_HOME/bin/catalina.sh. It will be available via System.getProperty(searcher.home) just like when you launch a command-line application.

The problem is I want to read a property file location in my program. If the program is of application type, this can be implemented by setting system property using -D searcher.home = command line argument. My question is, how to set system property in tomcat (and application using SOAP in particular java web services developer pack)? Any help on this is highly appreciated.

Perfectly valid and reasonable solution, though it requires folks using your app to tweak the startup command (most containers allow this). Another option is to simply set the property yourself in a startup servlet using System.setProperty(). Then, you can configure it in your web.xml using a configuration option or a JNDI entry. This does bring up a simple question: Do all of the webapps see the same System Properties? I can't imagine why not (assuming they share a JVM), but with all of the isolation that's enforced between the webapps, it gives one pause to consider.

I can't imagine why not (assuming they share a JVM), but with all of the isolation that's enforced between the webapps, it gives one pause to consider. That's why system properties are not a very good approach to configuring per-webapp behavior. However, they are convenient in standalone apps. An example approach that works pretty well for webapps and for standalone apps sharing the same code is to use a graduated search mechanism for configuration info -- like what the commons-logging package does in looking for logging configuration: look for a local properties file with a well known name, look for a JAR file that has the right file in its META-INF directory, look at a system property, fall back to a default.
