    Yes, in the beginning i was using the ireport plugin that i download from the netbeans page. After that, the plugin was give me some troubles and i decided to remove the plugin and use the ireport standalone.

     

    Then i start to install the ireport and the problems begin. Maybe the problem is that.

     

    How do i check this?. I am new in the use of netBeans and iReport.

     

    Thanks for the answer.
