Trying setClassLoader in SwingEngine, I could not get it to work until
changing the Class.forName line|| in Parser.java
Class initClass = Class.forName( classname , true,
this.engine.getClassLoader() ); // load update type
--kept getting ClassNotFoundException there. It looks like the
classloader "cl" field is not getting fully propagated.
Also, I have a custom component using initclass. The component takes an
Object argrument in its constructor. It wouldn't initialize until I
changed the argument checking in DefaultFactory.java
for (int j = 0; ctor != null && j < cParams.length; j++) {
//if (cParams[j].equals( Object.class )) {
// if (!cParams[j].equals( pTypes[j] )) {
// ctor = null; //dismissed
// }
//} else {
if (!cParams[j].isAssignableFrom( pTypes[j] )) {
ctor = null; //dismissed
}
//}
} // end for j - loop Ctor's parameter
I am using the getInstance of initclass to aquire an
already-instantiated singleton, but my custom component doesn't know or
need to know the type. That's why I'm giving it a subclass of Object
even though it takes Object. Only the method isAssignableFrom is needed,
because it also includes the "equals" case.
By the way, I'll be giving a talk including SWIX in the upcoming ADASS
conference on astronomical data reduction, and just yesterday my
application using SWIX was released, see
