Unable to get JavaFX to install
by Dan Thurman 28 Aug '09

28 Aug '09

I am trying to get JavaX installed on F11-Eclipse. Seems that I am missing some required components and need some directions: Added: http://javafx.com/downloads/eclipse-plugin/ Checked-boxed it, and attemted install results: ===================================== Cannot complete the request. See the details. Unsatisfied dependency: [com.sun.javafx.eclipse.editor 1.2.0.200905280115] requiredCapability: osgi.bundle/org.eclipse.wst.common.snippets/0.0.0 Cannot find a solution where both "bundle org.tigris.subversion.clientadapter [1.5.1,1.6.0)" and "bundle org.tigris.subversion.clientadapter [1.6.0,1.7.0)" are satisfied. Cannot find a solution where both "bundle org.tigris.subversion.clientadapter [1.5.1,1.6.0)" and "bundle org.tigris.subversion.clientadapter [1.6.0,1.7.0)" are satisfied. Cannot find a solution where both "bundle org.tigris.subversion.clientadapter [1.5.1,1.6.0)" and "bundle org.tigris.subversion.clientadapter [1.6.0,1.7.0)" are satisfied. Unsatisfied dependency: [com.sun.javafx.eclipse.feature.feature.group 1.2.0.200905280115] requiredCapability: org.eclipse.equinox.p2.iu/com.sun.javafx.eclipse.editor/[1.2.0.200905280115,1.2.0.200905280115] Unsatisfied dependency: [com.sun.javafx.eclipse.editor 1.2.0.200905280115] requiredCapability: osgi.bundle/org.eclipse.wst.common.snippets/0.0.0 Unsatisfied dependency: [org.tigris.subversion.subclipse.core 1.6.0] requiredCapability: osgi.bundle/org.tigris.subversion.clientadapter/[1.6.0,1.7.0) ===================================== What do I need to do/install to resolve: 1) osgi.bundle/org.eclipse.wst.common.snippets So does that mean I need the WST components? 2) osgi.bundle/org.tigris.subversion.clientadapter Is this related to subclipse v1.6x? I removed all of the subclipse 1.6x from the install list and it still keeps cropping up, why is that? In any case, subclipse v1.4.x is working with F11-Eclipse just fine and does not seem to cause any problems, so is it safe to ignore this "error"? Thanks! Dan

Problem w/ setting Sun's JVM via (g)alternatives?
by Dan Thurman 28 Aug '09

28 Aug '09

Since I am trying to get Eclipse's Ganemede working again, I am told that I would need to use Sun's JRE, however, I opted to use the JDK instead of the JRE. I have downloaded and installed Sun's JDK 1.6 & 1.5 into /opt and it looks good. I can via environment setting run the java -version tests. However I have added the /opt/jdk[...]/bin/java to the alternatives list in the 'java' category for both versions as follows: /opt/jdk.1.6[...]/bin/java priority: 1000 /opt/jdk.1.5[...]/bin/java priority: 500 then selected JDK v1.6, and tried to launch Eclipse. What resulted was a popup failure with the relevant entry: [...] -vm /opt/jdk1.6.0_16/bin/../jre/lib/i386/client/libjvm.so [...] Note: the entire "barf" is at the end of the line. Why is 'java' replaced with '../jre/lib/i386/client/libjvm.so'? Yes, the -vm path exist. Is this normal? Side question: is the JRE instead of JDK required? I wanted the JDK so that I can do Java development but I do not think there is a difference except only where the jre path is different. Thanks- Dan The "barf": =========================================== JVM terminated.

System Log Monitor
by Arnab Chakraborty 22 Aug '09

22 Aug '09

Hi, I am kind of new to open source programming and Linux (this is actually my first mail in any open-source mailing list). I am trying to design a software which can classify and store logs from different systems. It will be a client-server system, so that someone from the server can monitor the logs of different systems. I tried to do some research on the logging of data in fedora, but couldn't find many helpful sites. So I would be grateful if someone could tell me the working of the logging system in Fedora (briefly). Secondly, there are some log files in the directory */var/log* which couldn't be displayed as text. I used the System Logging software provided in System Tools to open them. But I would want to open them through my software, any idea how to do that? Looking forward to replies. Thanks in advance. Cheers, Arnab

Packaging YaCy
by Alexander Kahl 11 Aug '09

11 Aug '09

Hello dear Java developers and packagers, this is my first post to this list. I'm in the process of getting YaCy[1], a Java-based P2P distributed search engine and its dependencies ready to be packaged for Fedora in collaboration with upstream. While upstream was able to either kick out, replace or fork unmaintained dependencies, some of them remain and in turn pull in too many other dependencies I cannot handle myself so your help is *really* appreciated. In my opinion, YaCy would be a valuable addition to Fedora as it is matured, leverages overall usability of the distribution as a privacy-enhancing platform and we would be the *first* distro to offer a fully-integrated version of YaCy so please consider helping out, I'd really appreciate that! You can find the current state of progress at my Fedora People Space[2], the org-mode file[3] contains all dependencies and their current solutions. PDFBox[4] and FontBox[5] have been successfully ported from JPackage and are ready for review, jakarta-poi still needs porting from JPackage, jakarta-commons-fileupload is already maintained but the maintainer is unresponsive and we need a newer version. jakarta-commons-jxpath[6] is currently my biggest problem: It is owned but unreleased so I've acquired co-maintainership but ran into the problem that building requires mockrunner[7] which in turn pulls in so many dependencies (e.g. mockejb) I cannot handle myself. There is a thread[8] (in German only, sorry) about the ongoing collaboration with upstream; they have another board[9] for discussions in English the thread could also be continued at. Help! :) Regards Alex [1] http://yacy.net/ [2] http://akahl.fedorapeople.org/yacy/ [3] http://akahl.fedorapeople.org/yacy/yacy.org [4] http://akahl.fedorapeople.org/yacy/pdfbox-0.7.3-2.fc11.src.rpm [5] http://akahl.fedorapeople.org/yacy/fontbox-0.1.0-2.fc11.src.rpm [6] http://akahl.fedorapeople.org/yacy/jakarta-commons-jxpath.spec [7] http://akahl.fedorapeople.org/yacy/mockrunner.spec [8] http://forum.yacy-websuche.de/viewtopic.php?f=9&t=2232 [9] http://www.yacy-forum.org/

Alfresco packaging questions (a start)
by Karsten Wade 04 Aug '09

04 Aug '09

Does anyone have an idea or a friend with enough clue :) to supply a reasonable guestimate as to the time/effort involved in packaging Alfresco for Fedora? This page is a bit old and unmaintained: https://fedoraproject.org/wiki/Alfresco Anyone know someone at Alfresco who might care? Short summary - I've got a contact with engineers interested in Alfresco for their enterprise environment; they might commit resources to packaging (Fedora + EPEL); none of us know how much effort is involved; they don't want to do it alone, unless it's easy enough. For more details, you can read this short post: http://iquaid.org/2009/08/01/alfresco-packaging-for-fedora/ Thanks - Karsten -- Karsten 'quaid' Wade, Community Gardener http://quaid.fedorapeople.org AD0E0C41
