Hi,
I'm trying to use sablevm 1.0.8-3 (Debian) on a project which uses
JNI. The location of the libraries is being set using the
LD_LIBRARY_PATH environment variable. sablevm doesn't seem to be picking
up on this. The follow exception is produced:
java.lang.UnsatisfiedLinkError: Could not find library GTKJava.
at java.lang.Runtime.loadLibrary(Runtime.java:682)
at java.lang.System.loadLibrary(System.java:620)
at org.gnu.gtk.Gtk.static{}(Gtk.java:96)
at java.lang.Class.step8(Class.java)
at java.lang.Class.initialize(Class.java:204)
at com.tildemh.debbuggtk.BugWatcher.main(BugWatcher.java:454)
at java.lang.VirtualMachine.invokeMain(VirtualMachine.java)
at java.lang.VirtualMachine.main(VirtualMachine.java:88)
How can I fix this?
Please CC me - I'm not on this list.

Mark,
You can specify it with the java.library.path property
as follows:
sablevm -p java.library.path=3DDIR ...
I noticed this also. The reason is that Classpath code uses that
property instead of the LD_LIBRARY_PATH env var. I am not sure if this
is a Classpath/SableVM bug since libraries are located in a
"system-dependent" way. It might be more of an annoyance than a bug but
I will leave this for discussion on the developer's mailing list.

David or anyone - can you tell me how should I use the java.library.path property when I have more than one directory in LD_LIBRARY_PATH? Shall I use "-p" multiple times? or only once but separate the dirs with some separator? (which one? ":" ?) Cheers, Grzegorz B. Prokopski -- Grzegorz B.

I think it's a standard unix way of modifying the library path. I've also just noticed that sablevm doesn't check /usr/lib either. This is usually checked as default in most JVMs. -- .''`.

(which one? ":" ?) >=20 Grzegorz, The right way to do it is to use the ':'. (Actually, it uses the propert= y path.separator which defaults to ':' and should be defined as ':' on *nix system anyway). Properties are simple (key,value) pairs. There cannot be several pairs stored with the same key. I am not sure what SableVM does if one is specified several times. It might just use the last value? The actual code that uses it is in: sablepath-classes/src/java/lang/Runtime.java especially Runtime() and loadLibrary().

All command-line properties (e.g. "--property=3D...") are passed to the c=
lass-library.
In sablevm-class-library, src/java/lang/Runtime.java:
=2E..
private static void insertSystemProperties(Properties p)
{
=2E..
// get command-line passed value. These values may override
// default values above.
int count =3D getPropertyCount();
for (int i =3D 0; i < count; i++)
{
String property =3D getProperty(i);
int equal_position =3D property.indexOf('=3D');
String name =3D property.substring(0, equal_position);
String value;
if (equal_position < property.length())
{
value =3D property.substring(equal_position + 1);
}
else
{
value =3D "";
}
p.setProperty(name, value);
}
=2E..
So, if you pass the same property many times, p.setProperty(name, value) =
will be=20
called appropriately. The semantics of java.util.Properties indicate tha=
t only=20
the last assigned value will be retained.
As you see, I like to keep the native code to a minimum, in SableVM. I t=
ry to=20
do as much as I can in Java. When you modify SableVM, try to do the same=
=2E [I=20
know David already does this:-)]

Ah! You're using GetByteArrayRegion. This is easy enough to add. Could you send the list of the JNI functions your native library is calling. I know, SableVM should implement all of them, but I had a thesis to finish first... Right now, I have many things to do in parallel, so I try to do the strict necessary and delegate the rest to new SableVM developers. So, if you only need a few easy additional JNI hooks to add, I can try to do it fast. Etienne -- Etienne M.

Hi Mark, I have just checked in CVS the code for [Get/Set]*ArrayRegion. I have put a snapshot of SableVM with the fix in it at: http://www.info.uqam.ca/~egagnon/sablevm-snapshot/ You download the 4 files, give execution permission to the "build" script, the run "./build" as root. This should install the snapshot in /usr/local. So, to run this version, you should type "/usr/local/bin/sablevm". Please let us know if it helps.

Hi Mark, As promised, I added the missing JNI function. Please let us know if it works. Again, I have put a snapshot of SableVM with the fix in it at: http://www.info.uqam.ca/~egagnon/sablevm-snapshot/ You download the 4 files, give execution permission to the "build" script, then run "./build" as root. This should install the snapshot in /usr/local. To run this version, you should type "/usr/local/bin/sablevm [arguments]...". Have fun!

In my file, that line is located in GetByteArrayRegion that is still unimplemented. Could you confirm this is the one you need and I will implement it as it should be relatively easy and send a patch. We want to run as many applications as possible.

Great!, thanks I don't have a list of all which we use, but I can keep sending reports when I notice problems. FYI, the application I'm working on is BugWatcher, a program for viewing Debian bug reports. The interesting part is that this uses Java-GNOME, which is an attempt to create GNOME and GTK bindings for java - this is where the JNI is involved. -- .''`.

Hi Mark,
I have tried to install the java-gnome related debian packages, on my
debian/powerpc based PowerBook [a very nice laptop;)], but I got:
----- BEGIN -----
# apt-get install libgnome0-java
Reading Package Lists... Done
Building Dependency Tree... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:
Sorry, but the following packages have unmet dependencies:
libgnome0-java: Depends: libgtk0-java (= 0.8.0cvs20030320-1) but it is not
going to be installed
Depends: libgnome0-jni (= 0.8.0cvs20030320-1) but it is not
installable
E: Sorry, broken packages
----- END -----
I will file a bug about it, but meanwhile, where can I find the sources to
install and try to run your BugWatcher application (and all its dependencies)?
[Ideally, I'd like to get the shortest list of instructions to get it up and
running].
Also, is there any reason why the java-gnome jni code wouldn't compile under
PowerPC?
Thanks in advance,
Etienne
