use of pvTree Infragistics´JSuite

[Legacy User]

Hi all
I´m opening the java variant for a WinC function which uses ACTIVE/Tree control. I´m noticed that it would require to wrap the java bean as an ActiveX control, and have two questions:
1. It´s strictly required to do it, or it´s optional in the case you want to play with the control in designing the panel? The Platform Guide isn´t clear here, in my opinion.
2. It is mentioned there that you need to uninstall other java versions than 1.3, in order to register the beans; however, it seems to state that it is not required for java 1.5 and higher. What is your experience on it?

By the way, I´m using Plex 6.0

Any clarification, would be welcome

Another issue to ask for:
having the previous one question unsolved, I have compiled my function inherited from Active/ShowTree pattern, and received an unexpected error: a pv.awt.PVTree method not found (pv.awt.PVTree.getChildNode()). It happened into a native source code from pvTree. Have anyone seen it? I have declared pvAll.jar into user classes, and can´t belive it could happen (!)
