Retiring jogl
by Anthony Green 31 Oct '07

31 Oct '07

I am forced to retire the jogl package because parts of it are licensed under the SGI Free Software License B, which is not actually a Free Software license as per the FSF, and is explicitly not allowed in Fedora. The code in question is java code derived from SGI's OpenGL reference implementation (presumably in C). I've alerted the upstream jogl maintainers in this thread: http://www.javagaming.org/forums/index.php?topic=10718.msg138381#msg138381 AG

Fedora: setup Tomcat+Eclipse+GCJ environment
by Eric Damien 27 Oct '07

27 Oct '07

Greetings. I've been using fedora (6,7) for quite a time now, for c++ and regular java (gcj) programming. Now, I want to develop web application, using eclipse and tomcat. I installed Fedora eclipse and the tomcat packages. I downloaded the sysdeo plugin and that's where things started to go wrong: starting tomcat service on its own, I can acces the "http://localhost:8080" page. I setup sysdeo plugin but when I press the "srat tomcat" button, this is what I receive in the console of eclipse: 27-Oct-07 4:59:18 PM org.apache.tomcat.util.digester.Digester startElement SEVERE: Begin event threw error java.lang.NoClassDefFoundError: org.apache.catalina.mbeans.ServerLifecycleListener at java.lang.Class.initializeClass(libgcj.so.8rh) at java.lang.Class.newInstance(libgcj.so.8rh) at org.apache.tomcat.util.digester.ObjectCreateRule.begin(tomcat-util-5.5.23.jar.so) at org.apache.tomcat.util.digester.Rule.begin(tomcat-util-5.5.23.jar.so) at org.apache.tomcat.util.digester.Digester.startElement(tomcat-util-5.5.23.jar.so) at org.apache.xerces.parsers.AbstractSAXParser.startElement(Unknown Source) at org.apache.xerces.parsers.AbstractXMLDocumentParser.emptyElement(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanStartElement(xerces-j2-2.7.1.jar.so) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl$FragmentContentDispatcher.dispatch(xerces-j2-2.7.1.jar.so) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanDocument(xerces-j2-2.7.1.jar.so) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XMLParser.parse(Unknown Source) at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source) at org.apache.xerces.jaxp.SAXParserImpl$JAXPSAXParser.parse(Unknown Source) at org.apache.tomcat.util.digester.Digester.parse(tomcat-util-5.5.23.jar.so) at org.apache.catalina.startup.Catalina.load(catalina-5.5.23.jar.so) at org.apache.catalina.startup.Catalina.load(catalina-5.5.23.jar.so) at java.lang.reflect.Method.invoke(libgcj.so.8rh) at org.apache.catalina.startup.Bootstrap.load(bootstrap.jar.so) at org.apache.catalina.startup.Bootstrap.main(bootstrap.jar.so) Caused by: java.lang.NullPointerException at java.lang.Class.initializeClass(libgcj.so.8rh) ...20 more java.lang.reflect.InvocationTargetException at java.lang.reflect.Method.invoke(libgcj.so.8rh) at org.apache.catalina.startup.Bootstrap.load(bootstrap.jar.so) at org.apache.catalina.startup.Bootstrap.main(bootstrap.jar.so) Caused by: java.lang.NoClassDefFoundError: org.apache.catalina.mbeans.ServerLifecycleListener at java.lang.Class.initializeClass(libgcj.so.8rh) at java.lang.Class.newInstance(libgcj.so.8rh) at org.apache.tomcat.util.digester.ObjectCreateRule.begin(tomcat-util-5.5.23.jar.so) at org.apache.tomcat.util.digester.Rule.begin(tomcat-util-5.5.23.jar.so) at org.apache.tomcat.util.digester.Digester.startElement(tomcat-util-5.5.23.jar.so) at org.apache.xerces.parsers.AbstractSAXParser.startElement(Unknown Source) at org.apache.xerces.parsers.AbstractXMLDocumentParser.emptyElement(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanStartElement(xerces-j2-2.7.1.jar.so) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl$FragmentContentDispatcher.dispatch(xerces-j2-2.7.1.jar.so) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanDocument(xerces-j2-2.7.1.jar.so) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XMLParser.parse(Unknown Source) at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source) at org.apache.xerces.jaxp.SAXParserImpl$JAXPSAXParser.parse(Unknown Source) at org.apache.tomcat.util.digester.Digester.parse(tomcat-util-5.5.23.jar.so) at org.apache.catalina.startup.Catalina.load(catalina-5.5.23.jar.so) at org.apache.catalina.startup.Catalina.load(catalina-5.5.23.jar.so) at java.lang.reflect.Method.invoke(libgcj.so.8rh) ...2 more Caused by: java.lang.NullPointerException at java.lang.Class.initializeClass(libgcj.so.8rh) ...20 more Can somebody help with this?

About "Docs/Beats/Java" and jpackage
by Mary Ellen Foster 20 Oct '07

20 Oct '07

I was just looking at http://fedoraproject.org/wiki/Docs/Beats/Java and saw that it mentions installing packages from JPackage directly. Note that it's not actually possible, in my experience, to install packages from JPackage on Fedora 7 because of the following: - Fedora has an RPM-older version of jpackage-utils than JPackage - Fedora's jpackage-utils provides rebuild-security-providers, while JPackage's doesn't - All of the JPackage packages depend on their version of jpackage-utils - Many of the Fedora packages depend on rebuild-security-providers All of this means that JPackage packages can't really be used on Fedora. There are also issues to do with Lucene and Geronimo, but they're probably less fundamental. I described all of this in a post to the JPackage list in June when I first tried using JPackage on Fedora: https://www.zarb.org/pipermail/jpackage-discuss/2007-June/011536.html Also, the highest version of Fedora that JPackage seems to officially support is FC6 (see http://www.jpackage.org/yum.php). So I'm not sure it's helpful even to point people at JPackage for Fedora 8, because I'm not sure there's much useful they can do with it. MEF -- Mary Ellen Foster http://homepages.inf.ed.ac.uk/mef/

Problems building kawa on rawhide with ecj-on-gcj
by Anthony Green 16 Oct '07

16 Oct '07

I can't build kawa on rawhide (gcj 4.1.2) due to errors like the following.... [javac] 1. ERROR in /home/BUILD/kawa-1.9.1/gnu/lists/PrintConsumer.java (at line 9) [javac] public class PrintConsumer extends PrintWriter [javac] ^^^^^^^^^^^^^ [javac] Exception IOException in throws clause of Writer.append(CharSequence, int, int) is not compatible with PrintWriter.append(CharSequence, int, int) And, indeed, our PrintWriter.append methods don't throw IOException. Is this a bug? AG

Just wondering if javax.io / gnu.io packages (for IO eg RS232, parallel port etc) are going to be part of the Fedora Java suite? The project home is at http://www.rxtx.org/ Joe.

difficulties to use swt on fedora
by Patrice Dumas 15 Oct '07

15 Oct '07

Hello, I wanted to use swt.jar in a software (http://iriverter.sourceforge.net/download.shtml), but it turned out to be quite complicated to achieve. Maybe I am doing something wrong, but if it is not the case, things should certainly be ameliorated. I found swt.jar to be in libswt3-gtk2, in: /usr/lib/eclipse/swt-gtk-3.3.jar Why not in /usr/share/java/swt.jar? The compilation works with javac -classpath /usr/lib/eclipse/swt-gtk-3.3.jar:. org/thestaticvoid/iriverter/DVD.java On fc7, there seems to be a need to do export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/eclipse/ before starting the application or /usr/lib/eclipse/libswt-pi-gtk-3346.so isn't found, but I hadn't that issue in F8: !!! An unhandled exception occured: class java.lang.UnsatisfiedLinkError --- iriverter 0.16 --- --- Settings: --- --- !!! libswt-pi-gtk-3236: libswt-pi-gtk-3236.so: cannot open shared object file: No such file or directory !!! ....... more error messages ............ -- Pat

java arch dir names for mips
by Caolán McNamara 11 Oct '07

11 Oct '07

So in OOo we have.. #if defined SPARC #define JFW_PLUGIN_ARCH "sparc" #elif defined INTEL #define JFW_PLUGIN_ARCH "i386" #elif defined POWERPC64 #define JFW_PLUGIN_ARCH "ppc64" #elif defined POWERPC #define JFW_PLUGIN_ARCH "ppc" #elif defined X86_64 #define JFW_PLUGIN_ARCH "amd64" #endif // SPARC, INTEL, POWERPC But does anyone know what the arch names should be for the various mips of mipsel mipseb mips64el and mips64eb, I seem to see "mipsel" used by gcj for mipsel, but mips32 is being used by e.g. http://www.lemote.com/debian/pool/contrib/sun-java_1.5-lemote-b1_mipsel.deb I don't suppose there is an actual standard here, even a de-facto one ?

java packaging problem: unowned directories
by Anthony Green 11 Oct '07

11 Oct '07

A number of java packages have unowned directories. Some of them were recently called out on fedora-devel-list. Here's what I show on my FC-6 system. I recommend that package owners have a quick look at these... $ ls /usr/lib/gcj | xargs -n1 rpm -qf | grep "not owned by any" file /usr/lib/gcj/avalon-framework is not owned by any package file /usr/lib/gcj/bcel is not owned by any package file /usr/lib/gcj/classpathx-jaf is not owned by any package file /usr/lib/gcj/classpathx-mail is not owned by any package file /usr/lib/gcj/eclipse-changelog is not owned by any package file /usr/lib/gcj/eclipse-emf is not owned by any package file /usr/lib/gcj/eclipse-gef is not owned by any package file /usr/lib/gcj/jakarta-commons-beanutils is not owned by any package file /usr/lib/gcj/jakarta-commons-codec is not owned by any package file /usr/lib/gcj/jakarta-commons-collections is not owned by any package file /usr/lib/gcj/jakarta-commons-digester is not owned by any package file /usr/lib/gcj/jakarta-commons-discovery is not owned by any package file /usr/lib/gcj/jakarta-commons-lang is not owned by any package file /usr/lib/gcj/jakarta-commons-launcher is not owned by any package file /usr/lib/gcj/jakarta-commons-modeler is not owned by any package file /usr/lib/gcj/jakarta-taglibs-standard is not owned by any package file /usr/lib/gcj/jdepend is not owned by any package file /usr/lib/gcj/jzlib is not owned by any package file /usr/lib/gcj/ldapjdk is not owned by any package file /usr/lib/gcj/log4j is not owned by any package file /usr/lib/gcj/mockobjects is not owned by any package file /usr/lib/gcj/mx4j is not owned by any package file /usr/lib/gcj/tomcat5 is not owned by any package file /usr/lib/gcj/velocity is not owned by any package file /usr/lib/gcj/werken-xpath is not owned by any package file /usr/lib/gcj/xdoclet is not owned by any package file /usr/lib/gcj/xerces-j2 is not owned by any package AG
