Hi, That was all in lodfile what I have sending, I don't become the failure: "Runtime shutdown hook called, forceHalt: true" . I think my problem is in this code, here is a methode of PDFBox, hier i can read my pdf file, it's fine, a applet show me the pdf file,then I click on exit, here come the methode: System.exit(0) von PDFBox Package; so I think here force this exit that my Jboss Server must shut down. So is there a Property to set in Jboss that prevent this problem. -------------------------------------------------------------------------------------- String[] pdfargs = {filename}; try { PDFReader.main(pdfargs); } catch (Exception e3) { e3.printStackTrace(); return result; } -------------------------------------------------------------------------------------- Thanks, Radouane View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4005082#...
