Error opening CloverGUI

Dear Sr/Madan

I’m currently evaluating different solutions for ETL and Clover looks like a good option.
So, I decide to download and install full bundle of Eclipse + CloverGui.

I installed successfully and started playing around.
But when I try to open Clover.ETL perspect I’m getting an error like :

An error occurred while automatically activating bundle cz.opentech.cloveretl.plugin (5).

Question :
Do I need to install anything more to use CloverGui ?
My environment is Windows XP Professional and J2sdk 1.4.2.

Thanks a lot !

Olá Julio César, tambem sou do Brasil e tive problemas com o CloverGUI.

Depois de muita dor de cabeça, descobri que o problema era a versão do J2SDK, estava utilizando a 1.4.2, a mesma que voce está utilizando.

Desinstalei o J2SDK 1.4.2 e instalei a J2SDK 5.0 Update 9 e a perspectiva Clover.ETL funcionou perfeitamente, tente fazer isso

Abraço
Alan
