I'm trying to get fedora-idm-console up and running on OSX,
uname -a
Darwin mac03.pglan.com 9.4.0 Darwin Kernel Version 9.4.0: Mon Jun 9
19:36:17 PDT 2008; root:xnu-1228.5.20~1/RELEASE_PPC Power Macintosh
I've upgraded to latest JDK provided by Apple,
java -version
java version "1.5.0_16"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_16-b06-277)
Java HotSpot(TM) Client VM (build 1.5.0_16-130, mixed mode, sharing)
The java upgrade causes heap-space overruns using ant; bug report here,
"DirectoryScanner infinitely recurses on symlinks to parent directories"
https://issues.apache.org/bugzilla/show_bug.cgi?id=45499
so I've upgraded to a src-build of Ant HEAD,
ant -version
Apache Ant version 1.8.0alpha compiled on September 14 2008
which cures the problem.
Mozilla prereqs all build cleanly.
FedoraDS project's "console", "fedora-idm-console", "directoryconsole"
& "admservconsole" also build cleanly.
I've installed the locally built fedora-ds & fedora-admin jars locally,
ls -al ~/.fedora-idm-console/jars/
-rw-r--r-- 1 root wheel 2484780 2008-09-14 12:51 fedora-admin-1.1.2.jar

@ OSX shell, I launch
fedora-idm-console -D 9 -f console.log
and can successfully connect to FDS server running on a remote box (SLES).
If, in the Fedora Management Console GUI I click through to the
Servers & Applications Tab, and select the Server, I get a "Class
Loader Error" dialog,
"Failed to instantiate Server Object for Directory Server (fds):
com.netscape.admin.dirserv.DSAdmin"
@ console.log, I get,
...

Per discussion in #fedora-ds, I've installed Eclipse, & created an
Eclipse project for fedora-idm-console. Debugging the Eclipse-built
fedora-idm-console jar, exec breaks as above. The stack @ break is,
fedora_idm_console_jar [Java Application]
com.netscape.management.client.console.Console at localhost:50411

Where, for reference, in "ClassLoader.class",
347: } finally {
if (isChildmost) {
childmostCaller.remove();
if ((c != null) && name.startsWith("org.apache.") &&
( name.startsWith("org.apache.crimson.") ||
name.startsWith("org.apache.xalan.") ||
name.startsWith("org.apache.xml.") ||
name.startsWith("org.apache.xpath.") ) ) {
356: AccessController.doPrivileged(new PrivilegedAction() {
public Object run() { return
System.setProperty("apple.lang.DisableCompatibilityClasspath",
"true");
}});
}
I'm *guessing* this is OSX-specific, but am unclear as yet. I'll
further familiarize myself with Eclipse and the FDS code; in the
meantime, any suggestions as to what the problem maybe, or further
debug help would be great.
I can provide additional needed output from Eclipse to as needed.
Thanks.
