I am trying to set up Tomcat 5 on Fedora Core 5 and everything iw working find but i do not know how to set my classpath when using tomcat below is a few things that i have tried. I have found i can use the following code to print out the classpath that my program is actaully using, the code is: Get the System Classloader ClassLoader sysClassLoader = ClassLoader.getSystemClassLoader(); //Get the URLs URL[] urls = ((URLClassLoader)sysClassLoader).getURLs(); for(int i=0; i< urls.length; i++) { out.println(urls[i].getFile()); out.println("<br>"); } and the classpath that is printed is: /usr/java/j2sdk1.4.2_12/lib/tools.jar /etc/tomcat5/bin/dist/commons-daemon.jar /etc/tomcat5/bin/bootstrap.jar But i am not sure where this is getting set, i do have the following in my /tomcat5/bin/startup.sh export CLASSPATH=./mapscript.jar:.:/etc/tomcat5/webapps/my_test/WEB-INF/classes so why is this not my classpath at run time??

I am able to compile a java mapscript file from the command line using: javac -classpath ./mapscript.jar MapServerTest.java But when i try to turn my code into a servelt and run it over Tomcat i keep getting: java.lang.UnsatisfiedLinkError: no mapscript in java.library.path I have tried adding: export CLASSPATH=./mapscript.jar to my ./tomcat5/bin/startup.sh file but that does not seem to help. Am i missing a setting somewhere, why cant Tomcat find the .jar file? I have it in the same directory as my .java file and also in /common/lib and /shared/lib Thank you for any help that you can provide

This should probably go in the java-1.4.2-gcj-compat package (our JDK compatibility layer on top of gcj). We could simply "BuildRequire" openssl to generate and package the cacerts files. > Does that make sense?

gcjwebplugin has landed in Rawhide
by Thomas Fitzsimmons 03 Aug '06

Hi, gcc-4.1.1-12, which contains libgcjwebplugin.so, went into Rawhide last night along with java-1.4.2-gcj-compat-plugin which installs an alternatives-managed "libjavaplugin.so" symlink in /usr/lib/mozilla/plugins. I closed the long-standing "Inclusion of gcjwebplugin" bug: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=127537 and updated the release notes with a "Handling Java Applets" section: http://fedoraproject.org/wiki/Docs/Beats/Java Rawhide users can install gcjwebplugin with "yum install java-1.4.2-gcj-compat-plugin". Please try this out, file bugs and comment on the release note additions. The GNU Classpath AWT and Swing code was in a state of flux when the backport that included gcjwebplugin was done (because of a large Java2D rewrite to make the Cairo backend the default), so there are some regressions in AWT and Swing applications for FC6test2. My post-test2 plan for gcjwebplugin is to gage the reaction of Rawhide users, and also to do another GUI backport from GNU Classpath HEAD to Fedora's libgcj, to fix the AWT and Swing regressions. If the reaction turns out to be overly negative, even after the new AWT and Swing backport, we can always make gcjwebplugin not installed by default, for FC6test3. For FC6test2 though, it is installed by default if the Internet group is selected. Tom

fc6 extras java status
by Anthony Green 01 Aug '06

01 Aug '06

Things are a little ugly in fc6 extras java land... * Azureus makes my computer practically unusable because of libgcj's new SecureRandom implementation. I've filed a bug for a work around here: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=200653 Mark tells me this is the root cause of some crypto test timeout problems on the autobuilder as well. Casey says that this same code doesn't seem to have a problem on jamvm. * RSSOwl no longer fails to start because of the zip problem (thanks tromey!), but now crashes in _Jv_ClassReader::checkExtends (super = 0x3). I'm rebuilding libgcj with -O0 -g3 to debug. * I've updated jogl to jsr231 1.0 beta 5. The good news is that it builds sans patching! The bad news is that demos crash the X server (like, try resizing the gears demo). I think this is an X problem, so I'm going to push this out anyways because the latest WW2D (and "WW2D plus one", which looks awesome -- http://www.alpix.com/3d/worldwin/WW2d_Java.html) use this version of the jogl API. * kawa is fine.

Do we still need these packages in fc6 or did they get merged into libgcj? Anybody know? Thanks, AG
