JSP,Beans and PARAMS


Hello everybody,

Hopefully anyone can help me, because I'm trespassing the thresholds to
insanity.

I wrote a simple java-bean with get/set-Methods for accessing Properties

  public int getActualStep() {return ActStep;}
  public void setActualStep(int step) {ActStep=step;}

Another class (Jb2.class) inherits of this class (Jb1.class)
both are in package foo

Jb2.class does not explicitly overload the set/get-methods

Now I got a *.jsp-page: jb.jsp

jb.jsp looks like this:

	<html>
	<head>
	...bla...
	<body bgcolor="#ffffff">

	<%@ import="foo.Jb2" >

	<Bean name="foobean" type="foo.Jb2" scope="request"
		create="yes" introspect="true">
	<PARAM ActualStep="1">
	</Bean>

As long as i keep out the PARAM-tag everythings fine. the Moment I use the
param-tag to set the property ActualStep JSP answers with:

Bean foobean of typefoo.Jb2 has no property named ActualStep

I tried almost every combination of implementing Serializable, again  
letting it,
copying the get/sets to Jb2, inheriting from Simple-Bean and deleting this
inheritance again and finally even created ParameterDescriptors according
to the beans-specification, but nothing worked, so I think it might be
anything with the jsp-tags for the Beans I did not understand.
The explicit call of the get/sets by calling the method-name works
properly

Please - has anybody an idea?

best regards
	Alex
