How make a process using Beanshell Script?

[Jose Francisco Rodriguez Chavez]

I'm trying to make a process using Beanshell Script

In the rule screen

beanshell:DummyProcess

org.adempiere.webui.window.FDialog(1,null,"This is a test !!!");

return "";

In the process screen

Class name: @script:beanshell:DummyProcess

When execute process, it show this following message:

the script should be like this:

org.adempiere.webui.window.FDialog.info(1,null,"This is a test !!!");

return "";
