Re: Embedded Felix giving NumberFormatException

[Richard S. Hall]

Well, I sort of take back what I said below...since you are not 
launching with the standard launcher, property substitution does not 
happen in the roland.properties file, so you have to overwrite that 
value with a "real" value.

I will keep playing with it...

After a quick look at your code, I noticed one thing that looks 
somewhat strange...I don't know if it is the root of your issues, but 
it is something to look at...

Below you appear to read Felix' configuration properties from the 
roland.properties, which sets the org.osgi.framework.system.packages 
property inside of it, including all of the packages exported from the 
underlying JRE. Your code below then overwrites this value and sets it 
to only export the core OSGi packages along with your "simpleservice" 
package.

The end result is that no JRE packages are being exported any more 
after you overwrite the value. To remedy this situation, you should 
either:

  1. Add your "simpleservice" package to org.osgi.system.packages
     property in roland.properties or
  2. Append your "simpleservice" package to the existing value in the
     code below.

I am not sure if this will solve anything, but I am still working to 
get your example to compile since the pom files included with it are 
not working for me.

One other minor thing I noticed below, you have an extraneous ';' 
character when you add your "simpleservice" package.  I think Felix 
would ignore this, but you should probably still remove it. The ';' is 
used to separate packages that share attributes or to separate the 
attributes themselves.

I will keep trying to build your code. Let me know if any of the above 
makes a difference or if you discover the issue in the meantime.

   private BundleContext m_context = null;

   public void start(BundleContext context)

   }

   public BundleContext getContext()
   {
       return m_context;
   }
}

Perhaps you should let us see your code for launching Felix and
installing the bundle.
