XND and Mac OSX 10.5.8

[David Kennedy]

Hi, I'm trying to run xnat desktop (xnd) on Mac OSX 10.5.8

I followed the chmod instructions at
http://groups.google.com/group/xnat_discussion/browse_thread/thread/df7e71851534c69a

This 'works' only long enough to generate an error "An error has
occurred, see the log file".

The log file contents is included below, but I can't make heads or
tails of it.

Any suggestions? Thanks

Dave Kennedy

Hi,

You'll need to update Java to 1.6 version. Try searching for java update through the standard update on your Mac.

Arg, I'm still in Java pain, I've done the http://support.apple.com/kb/DL1359
update:

About Java for Mac OS X 10.5 Update 10

Java for Mac OS X 10.5 Update 10 delivers improved compatibility,
security, and reliability by updating J2SE 5.0 to 1.5.0_30, and
updating Java SE 6 to 1.6.0_26 for 64-bit capable Intel-based Macs.

I'm running 2 x 2.8 GHz Quad-Core Intel Xeon

> java -version from a terminal says:
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03-384-9M3425)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02-384, mixed mode)


But the XND error persists with a similar log file. Is there any
cryptic configuring I have to do to make it so xnd sees my java
version "1.6.0_26"???


Guess I need a new computer ;-(

David,

Have you tried using /Applications/Utilities/Java Preferences to set your default Java implementation? Depending on how exactly things are set up, it might be necessary for you to log out and back in, or even to restart your machine, after changing that selection.

Check the value of the PATH and JAVA_HOME environment variables. If those are still pointing to a 1.5 JDK, that's your issue.

Also, you may also want to look at the symlinks under /usr/bin or wherever your java/javac commands are coming from (just do which javac). There are also symlinks to various versions of the JDK. They'll be something like /System/Library/Frameworks/JavaVM.framework/Versions and see what's set as current. That's how mine's set up on 10.6.8, so the folders may be a bit different on 10.5. I can't vouch for the technical accuracy of this post, but it may help:

Even with Java 1.6 set up correctly xnd fails to start, complaining
that it can't load libserver.dylib (which does exist; see below).
This is only a problem on Mac OS 1.5, not 1.6. I can't find anything
helpful for this on line (most of the solutions recommend switching to
Java 1.5!) -- has anyone run into this before?

Thanks,
c

xnd can be packaged with either carbon (earlier Mac) or cocoa (later Mac) eclipse libraries. Here's a reference which hopefully can help choose a right distribution for your Mac:
http://eclipse.dzone.com/articles/eclipse-galileo-mac-cocoa-or.

Although I never had a problem with using carbon distribution, trying cocoa for newer Mac's may be worth a shot.
Please try 32 bit or 64 bit cocoa versions (I added distributions v0.93 to download directory: http://nrg.wustl.edu/xnd/download/) and see if it helps.

That works; thanks!
