How do I set System properties within WL6.0?

Question

I am setting WL6.0 up to have a startup class, but this class needs to
read system properties which have not yet been set. How do I set these
up within weblogic? I was able to get the startup class set up, but it
needs these system properties to continue.

Correct on all points. The one advantage of doing this in java is that you can more easily do more
complex things like accessing configuration information from a remote data store (like a database).

These are not needed if you simply replace java ...lots of options... weblogic.Server with
java ...lots of options... startmyWLS in the script which starts WebLogic, but, on the other
hand, this solution is no different from simply adding -DmyProperty=myValue to the startup script
(I think that the ultimate goal is the ability to deploy(and redeploy!) components,
without any mods to the particular vendor's startup scripts of anything of that nature).

Thanks to robert for a quick workaround..
I tried to start the WLS with the following piece of code and actually i need to set
some additional properties
for successful server startup.
Here it is
import java.util.Properties;
public class startmyWLS
public static void main(String[] args)
Properties props = System.getProperties();
props.put("myProperty", "myValue");
props.put("bea.home", "E:\\bea");
props.put("weblogic.Domain", "mydomain");
props.put("weblogic.Name", "myserver");
props.put("java.security.policy",
"E:\\bea\\wlserver6.0\\lib\\weblogic.policy");
System.setProperties(props);
weblogic.Server.main(args);
Make sure you run this from E:\bea\wlserver6.0., as it tries to read config.xml
config\[your-domain-name] from this
directory.

That won't work since it has to be 'outside' of the code. It's a service, and
services are started when weblogic is started up, not when I call a bean.
And it has to be dynamic, since the properties will vary on evry installation.

You can also use System.setProperty() or a combination of
System.getProperties() followed by a System.setProperties()...

They are not normal system properties. I'm using some open source code, and
it requires settings to be system properties, but they are specific to the
application, which means that they are not already in the system
properties. I know how to get them, and after some more research, you can
set them on the command line when starting up weblogic. However, is this
the best way to set system properties?

What "system properties" are you trying to find?
