Java Swig bindings - error in SmokeTest

Hi all,

I've now got a MSVC make file for the Java Swig bindings working - 
except it doesn't quite pass the Smoke Test. The error is:

Exception in thread "main" java.lang.NoClassDefFoundError: MyExpandDecider
Caused by: java.lang.ClassNotFoundException: MyExpandDecider
         at java.net.URLClassLoader$1.run(URLClassLoader.java:200)
         at java.security.AccessController.doPrivileged(Native Method)
         at java.net.URLClassLoader.findClass(URLClassLoader.java:188)
         at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
         at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:276)
         at java.lang.ClassLoader.loadClass(ClassLoader.java:251)
         at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319)

If I comment out lines 24-41 and lines 124-126 it passes. Can anyone 
(with a bit more Java knowledge perchance!) let me know how I might fix 
the SmokeTest.java file? There are some comments near these lines that 
give me the impression they might be needing a fix anyway....

Cheers

Charlie

Is that the *entire* backtrace? It doesn't seem to contain any user
code at all. Which release is that? Your line numbers don't seem to
match my 1.0.6 copy. (Via SVN, so I may have something wrong of course.)

Yes, that's all I have. I added -verbose and got this (I've clipped out 
the bits that don't seem to relate). I really don't know Java, so shout 
if you can suggest a way to get more information.

clustering

Hello

I'm new to this list (and to xapian) and I would like to use this
wonderful library from PHP within an IR project.

I read some messages about clustering and I saw some code about it in
a branch, now the question is if, at your opinion, is there any hope
that I could use that function within one month or the like.

I have some (very limited knowledge) of C/C++ and I can
compile/cross-compile under Linux (debian/ubuntu) if needed.

Any hint about this (or other options) would be highly appreciated.

Thanks in advance.

I believe the current state is that it works, but I'm not sure when it
will actually be released, and until then the API could change.

So if you want to give it a try, feel free.

Cross-compiling should work.  You don't mention what to, but mingw and
cygwin cross-compiles have both been tested fairly recently.

Cheers,

Thanks for your reply, I will try it for sure.

Please tell me if I'm wrong: is this the right command to fetch that branch?

svn co svn://svn.xapian.org/xapian/branches/clustering xapian

Do I need to do anything special (which is not in the readme) in order
to compile or enable the clustering feature and PHP bindings for it?

Yes, that looks right.

To build an SVN checkout, you need to follow the instructions in
xapian-core/HACKING, which the top-level README directs you too
(though not as firmly as it really ought to):

http://svn.xapian.org/branches/clustering/xapian-core/HACKING?rev=10120&view=markup

I don't know if the clustering has been tested from PHP - Richard
has done most of the work on it, so he's the one who'll know.

Cheers,
    Olly

Thanks.

I successfully built the package and I'm happily testing the
clustering feature from PHP.

Xapian-omega does not build

Re: Xapian-omega does not build

Hi,

This problem seems to only exist with xapian-omega 1.0.6, if used with
xapian-core 1.0.5. If I use xapian-omega 1.0.5 I can compile with no
problems. I take it this means the version numbers of xapian-core and
xapian-omega must match?
