    lookupPrintServices return an empty array with jboss 7

      Hello,

      I migrate an application from jboss 4 to jboss 7.1.

      There is 1 thing that I can't resolve with the lookupPrintServices method.

       

      This method return an array with all printers installed on the server. It works fine with Jboss 4, 5 or 6 but not with Jboss 7.

      After research on that problem, I see that the security is activated by default with Jboss 7.

       

      So I use the secutityManager with a server.policy file containing only :

      grant{ permission java.security.AllPermission;};

      But the method return an empty array.

       

      Do you know if there is an other thing to do to allow again this method to access the printers ?

       

      Here is a simplified code of jsp with the problem :

       

       

      <%@ page language="java" import="java.util.*,javax.print.*,java.awt.print.*,java.io.*" 
      %>
      <html>
      <body>
      <%
      try {
          SecurityManager security = System.getSecurityManager();
          security.checkPrintJobAccess();
          
          PrintService[] services = PrinterJob.lookupPrintServices();
          System.out.println("defaultPrinter " + defaultPrinter);
          
          System.out.println("===> " + services.length);   //return 0 ???
      } catch(Exception ex) {
          ex.printStackTrace();
      }
      </body>
      </html>

            From the description here I believe your problem could be class loading related - can you enable verbose classloading in the stand alone client to identify what classes are actually loaded when it works.

              {code}

              public class PrintService {

                  public static void main(String[] args){

                      javax.print.PrintService[] services = PrinterJob.lookupPrintServices();

                      System.out.println(services.length);

                  }

              }

              {code}

               

               

              Executing java -verbose:class PrintService this is the output:

                Hi Darran,

                Thank you for your answer. It's a good remark.

                 

                In the standalone configuration I have more classes loaded.

                I don't understand why with Jboss, there is a lot of classes that are not loaded.

                It is probably the problem but I don't see how force jboss to load the classes as a standalone application.

                I search if there is a specific configuration for a windows server.

                I keep you inform if I found more elements or a solution.

                  Is there any new about? This is gonna crash down an entire (big) project of mine. Solving this issue is fundamental. Hope someone to have some idea about.

                  Thanks

                    No.

                    I didn't find a solution exept keeping my project running under jboss 5.

                      The cause of this is that the META-INF/services/javax.print.PrintServiceLookup resource from the JRE isn't available in your classloader. Without that there are no implementations of the printer lookup available, so it does not find any printers.

                       

                      To fix this:

                      1) Edit modules/sun/jdk/main/module.xml and add this with the other paths:

                        <path name="sun/print"/>

                      2) Open up resources.jar from your JRE, and extract META-INF/services/javax.print.PrintServiceLookup (and optionally the others) into modules/sun/jdk/main/service-loader-resources/META-INF/services

                          just for info, this issue was fixed in latest nightly builds.

                            https://issues.jboss.org/browse/AS7-5158 fixed it so you don't need to do part (1), but you still currently need to do (2) because the JDK's META-INF/services is not visible to other modules.

                                  Your solution works fine.

                                    I have tried this solution and re-started the Jboss but it still does not work for me.

                                    I am using the Jboss 7.0.6 in Vaadin framework.
