Re: [Objectscript-users] Embedding java. Examples.

[Rob C. <ro...@ti...>]

There are a couple caveats with dealing with java packages...

1) pkg.system.declareJavaPackage() is a bit simplistic... if you  
declare "a.b.c" this does not automatically declare the existence of  
"a.b"... one of these days, maybe I'll fix this... or maybe Sun will  
come up with a more reliable way to detect the existence of some java  
package so there would be no need for this ugly hack in the first place.

So you would (potentially) need to have something like:

   pkg.system.declareJavaPackage("com.novatechnolgias");
   pkg.system.declareJavaPackage("com.novatechnolgias.xf");

If someone out there knows any reliable way to detect the existence  
of a package, please let me know... unfortunately it seems that  
java.lang.Package.getPackage() only works if some java class from  
that package has already been accessed from the java environment.

2) being in the system classpath is different from an "import"... ie.  
you still need to use a fully qualified package name, or an import, ie:

   var pp = new com.novatechnolgias.xf.pruabmBsh();

or:

   mixin(com.novatechnolgias.xf);
   var pp = new pruabmBsh();

3) is xf.javax.swing.JMenuItem the full package + classname?  Or is  
it com.novatechnolgias .xf.javax.swing.JMenuItem?  If the former,  
then you will need to create a new JavaPackage object for the "xf"  
package root:

   const var xf = new JavaPackage("xf");

if the later, you will need something like:

   const var xf = com.novatechnolgias.xf;

(after the necessary pkg.system.declareJavaPackage stuff)
