Problem with WebViewer

ner83

Hello,
I'm trying to make preview of the report with WebViewer method. When i'm trying to call that function eclipse shows me errors. I call the function like this
WebViewer.display("reportdesign/DocumentPR.rptdesign", WebViewer.HTML, browser, "run");

Help me please

Errors:

Are you running this as a Eclipse Application?
