I find to work very unreliably:
It works in one project but not in another.
It does not seem to work well when the extended abstract-class is in a
non-default [explicitly named] package.
I would appreciate any info/suggestions on this.
---------- Question 1 ----------
Why is the global-classpath set in prj.el good enough for compiling/running
from jdee, but not for jde-wiz-extend-abstract-class ?
---------- Question 2 ----------
Why is a 'core' class like 'InputStream' not locatable by jdee/beanshell?
I've seen exchanges on this mailing-list about the issue [and suggestions to
retrieve diagnostic information], but I have not been able to resolve the
problem.
This is my [sample] class -- which I want to have extend java.io.InputStream:
> package my.scratch.jde;
> import java.io.InputStream; // also tried adding this *before* calling
> jde-wiz-extend-abstract-class: did not help
> /**
> * Describe class IStrm here.
> * Created: Mon Jan 25 11:42:45 2010
> *
> * @author <a href="mailto:---";>---</a>
> * @version 1.0
> */
> public class IStrm {
> /**
> * Creates a new <code>IStrm</code> instance.
> */
> public IStrm() {
> }
> }
I tried jde-wiz-extend-abstract-class with:
1.
InputStream -- no luck: lisp/java error/exception ['NullPointerException']
2.
java.io.InputStream -- worse: abstract class java.io.InputStream not found on
current classpath !
I'm pasting here the lisp-error+java-NPE seen for case '1.' [package-name
omitted in abstract-class name].
