Description of problem: When using Java's javax.print.PrintServiceLookup.lookupPrintServices method, it returns an empty list of print services if the "Browsing" directive in CUPS is turned on. If the "Browsing" directive in CUPS is turned off, it works correctly returning a list of printers. Version-Release number of selected component (if applicable): 1) Linux : Redhat 5.4 (2.6.18-194.el5 #1 SMP) 2) CUPS : cups-1.3.7-11.el5 3) JAVA : java version "1.4.2_24-rev" Java(TM) Platform, Standard Edition for Business (build 1.4.2_24-rev-b06) Java HotSpot(TM) Client VM (build 1.4.2_24-rev-b06, mixed mode) How reproducible: Always Steps to Reproduce: 1. There are two print servers using function below --> /etc/cups/cupsd.conf : Browsing 2. Compile the Java test case program provided with this bug report: $ javac Printer.java == Printer.java == import javax.print.*; import java.io.*; import java.net.URI; public class Printer { public static void main( String args[] ) { PrintService[] services = PrintServiceLookup.lookupPrintServices(null, null); for (int i = 0; i < services.length; i++) { System.out.println(services[i].getName()); } } } 3. Run the java: $ java Printer.java Actual results: Expected results: returned empty list.
