can not access a member of class ... with modifiers

[scheintod]

Hi Forum,

I'm using SessionBeans with a

@Destroy
@Remove
public void destroy() {
}

Method. Seam complains:

WARN [org.jboss.seam.Component] Exception calling stateful session bean default @Remove method: myBean
java.lang.RuntimeException: exception invoking: destroy
at org.jboss.seam.util.Reflections.invokeAndWrap(Reflections.java:134)
...
Caused by: java.lang.IllegalAccessException: Class org.jboss.seam.util.Reflections can not access a member of class MyBean with modifiers "public"

This problem puzzles me for hours now. What could it be?

Best thanks,

Florian

Do you have defined such method in the business interface?

[scheintod]

yup. I have:

public void destroy();

[fernando_jmt]

So, it seems something related with some properties' modifiers.

I saw something related here:

Post the whole class.

Here you are:

import de.axone.shop.user.User;

@Local
public interface Context {

public void create();

public void destroy();

public Client getClient();
public Shop getShop();
public User getUser();
public Locale getLocale();
public SelectorQuery getSelectorQuery();
}

@Override

Make the class public.

[scheintod]

oh. ok. I thought it must be something _very_ stupid. Well, it is. I missinterpreted the error message and thougt I had too much and not to less "public". Now its obvious.

Thanks very much.
