You need a java jre because sesame2 is written in java. (Soprano uses it through JNI)

I would recommend to get the recent sun jre that works fine here with sesame2.

I have opensuse 11.1. could you tell me which could be the package to install?

linux-ax95:/home/marco # rpm -qa | grep java
timezone-java-2008h-2.16
java-1_6_0-openjdk-plugin-1.2_b11-22.13
java-1_6_0-sun-1.6.0.u11-1.1
java-1_6_0-openjdk-1.2_b11-22.13
java-1_7_0-icedtea-1.5_b24-15.8
java-1_5_0-gcj-compat-1.5.0.0-56.61
linux-ax95:/home/marco # rpm -qa | grep jre
linux-ax95:/home/marco #

I would go for java-1_6_0-sun-1.6.0.u11-1.1

I have it..

i did: ln /usr/lib/jvm/java-1.6.0-sun-1.6.0.u11/jre/lib/i386/server/libjvm.so /usr/lib
indexing now starts, but has some issue

some issue?

I found that to use the sesame backend, you also need the java devel package installed. There's a bug report in the opensuse bugtracker about this issue : https://bugzilla.novell.com/show_bug.cgi?id=461599

solved, thanks a lot

Well, I never had to do that. For me all it took was to install the sesame2 backend, and install the corresponding java-devel package. Didn't know about the java-devel package at first, but after that one was installed the indexing started to work the next time I turned on the computer. Don't know why nothing worked with the default redland backend though, but from what I've gathered the sesame backend is better anyway

Well redland is not the default. Nepomuk uses sesame2 as default. With the slower (up to the point to be useless for some things) redland backend indexing in Nepomuk is disabled because it is too slow for it..

The problem is, that some distros do not package the sesame2 backend or do not install it by default.

Sorry about that. I should have been more explicit and said "Redland as being installed by default in OpenSUSE" Well, 11.1 and the factory repos at least. Don't know what they've planned for 11.2, which is still far (relatively speaking) into the future.

I think that lucene would index this far quicker. I understand that nepomux integrates lucene (is this correct?) and this shows what a lot of extra work is being done.
I started the server like this:-
nepomukserver 2> nepomuk.out
Some of this extra work can be seen in this file which is now >25 meg.
Anyone know of further resources to understand nepomuk further?
I hope this thread is still being monitored, I know it is a bit old, but these are the instructions I followed, more or less.
