Java SWT issues. Looking for help.

[trmentry]

I'm trying to get Crashplan (http://www.crashplan.com) running on Gutsy. I extracted the archive and can get the engine running.

When I try and run the dekstop gui I get the following:


~/bin/crashplan$ ./CrashPlanDesktop.sh
chris@kashyyyk:~/bin/crashplan$ Exception in thread "main" java.lang.UnsatisfiedLinkError: no swt-gtk-3346 or swt-gtk in swt.library.path, java.library.path or the jar file
at org.eclipse.swt.internal.Library.loadLibrary(Unkno wn Source)

at com.backup42.desktop.CrashPlanDesktop.<init>(CrashPlanDesktop.java:117)
at com.backup42.desktop.CrashPlanDesktop.main(CrashPl anDesktop.java:81)


So I figured out it was looking for the libswt3.2-gtk-java package. I installed it and still got that error above. I cheated and put a symlink in crashplan/lib point to it in /usr/lib/java

But now I get the following:


~/bin/crashplan$ Exception in thread "main" java.lang.UnsatisfiedLinkError: no swt-pi-gtk-3236 in java.library.path

at com.backup42.desktop.CrashPlanDesktop.<init>(CrashPlanDesktop.java:117)
at com.backup42.desktop.CrashPlanDesktop.main(CrashPl anDesktop.java:81)


The shared objects for swt appear to be in /usr/lib/jni. However if I make sym links to libswt-pi-gtk-3236.so in crashplan/lib or /usr/lib/java or where ever I still get the above error. I'm a bit stuck.

I've read about doing a

java -Djava.library.path=<blah> but not exaclty sure where to point that at. I don't want to break java.. and haven't been able to display java's env settings that it currently has in case I want to revert my changes.

Any pointers?


On a side note, Crashplan support says that the next version of the linux client will have an 'installer' that will fix these types of issues on Ubuntu. However I'm wanting to try it out now. :D

Any advise would be welcome.

thanks

What java are you running, is it 32bit? If so it is looking for 32bit versions of that file. The solution is to get the 32bit version of that file (http://packages.ubuntu.com/cgi-bin/download.pl?arch=i386&file=pool%2Funiverse%2Fe%2Feclipse%2Flibswt3.2-gtk-java_3.2.2-3ubuntu3_i386.deb&md5sum=8d1d6ee7c0c7ba7f7212c7dfb75e8f08&arch=i386&type=main) then extract it. Do not force install the package, this will overwrite the 64bit files that other things may need.

sudo dpkg -x /path/to/the/file.deb

This will extract the internal tree of the deb file. Next look in that tree for /usr/lib and copy the files in it to /usr/lib32 in your system.

I would think I'm running 64 bit... I just apt-get install java-common, etc and let it do the rest.

I tried what you said and still no joy.

The sym links are all there as well in /usr/lib(32)/java

One thing I have noticed... is I have

/usr/lib has a lib64 symlink pointing to it as well
/usr/lib32

PLus

/lib with a /lib64 pointing here too.
/lib32


The lib dirs off / don't have java stuff in them... should there be some symlinks in there as well?

I have a similar problem trying to run xmind (http://www.xmind.org/). This eclipse based application is available only as a 32-bit java application. Using the 32-bit sun jre v1.6.0, I am able to get to the splash screen of the application before it fails. In the log file, there is the line
Root exception:
java.lang.UnsatisfiedLinkError: no swt-gtk-3346 or swt-gtk in swt.library.path, java.library.path or the jar file


I have installed the 32-bit libswt3.2-gtk-java and libswt3.2-gtk-jni packages with the method explained by Kilz (download, extract and manual copy to /usr/lib32). This does not help :(

How can I tell the jvm to find these files? I have tried to copy the .jar and .so files in /usr/lib/jvm/ia32-java-6-sun/jre/lib and /usr/lib/jvm/ia32-java-6-sun/jre/lib/i386 with no visible change. If I copy them to the current directory it does not help either.

Thanks for any help,

There are no 32-bit and 64-bit Java applications. So the application you are trying to run is not a "32-bit Java application" - because that doesn't exist. A Java program will run on a 32-bit or 64-bit Java runtime environment without any changes.

SWT, which is the GUI toolkit of Eclipse, includes a few native libraries. You need the 64-bit version of those native libraries if you're using a 64-bit operating system.

[pboulet]

Ok, a java application is world length independent (except for native libraries) but then why is it not even showing the splash screen with the 64-bit jvm is a mystery. The launcher is perhaps limited to 32 bit linuxes.

Concerning the 32-bit swt native files, I have found them and installed them but the application does not find them. Furthermore the application launcher does not seem to accept any command line options, so I am a bit stuck. I would not like to revert to 32 bit ubuntu but I use xmind daily :(

Hi!
I had a similar problem (with mvPod). I'm using Ubuntu (AMD64).

I copied the swt.jar from to the lib-directory that came with the program files (mvPod):
cp /usr/lib64/java/swt.jar /path/to/mvpod/lib/
A link should work, too.

I got rid of the
"no swt-gtk-3349 or swt-gtk in swt.library.path, java.library.path or the jar file"
but got instead the
"no swt-pi-gtk-3236 in java.library.path"
error.

I typed the following before trying to start the program (my libswt-pi-gtk-3236.so is located in /usr/lib/jni)
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/jni
and everything works fine!

Hope this helps...
