When I try to access http://localhost:8080/autosparql-lite/, I get a server error:

[KonradHoeffner]

AutoSPARQL TBSL is under rework at the moment. A demo can be used at http://linkedspending.aksw.org/tbsl. I will keep you up to date when the rework is finished.

[ziodave]

Thanks Konrad!

[arunprasathe]

hi i am getting the same issue any chance its fixed. This happened when we did mvn jetty:run .

[KonradHoeffner]

Please post your error log arunprasathe, there seems to be a Maven issue at the moment which I am investigating right now.

[Protino]

Any updates on this issue?

[KonradHoeffner]

Due to lack of resources we unfortunately cannot maintain TBSL anymore. I recently made sure that it at least compiles, though, but I receive a similar error on running:

[Protino]

There is no CacheEx class in the jena_sparql_api/cache/extra package anymore. But something is trying to access this class. I digged a lot but couldn't find anything.
May be you could try this link that explains NoClassDefFoundError Link.

Anyways thanks for taking your time.

[RicardoUsbeck]

Maybe @Aklakan can help?

[CarlHoo]

You can download jena-sparql-api-core-2.10.0-22.jar and add into your project, it's the latest version include class CacheEx.

[Cassendra4]

I also get this error. can you please help me.

[nmvijay]

The jena-sparql-api-core-2.10.0-22.jar contains the org/aksw/jena_sparql_api/cache/extra/CacheEx, but if you update your pom with 2.10.0-22, then you get Caused by: java.lang.ClassNotFoundException: org.aksw.jena_sparql_api.cache.extra.CacheFrontend, which is there in 2.13.0-5

So this is chicken and egg problem

[KonradHoeffner]

I got a different error, namely that the artifacts jena-arq and com.googlecode.concurrentlinkedhashmap were not found, which I fixed by increasing jena-arq version to 2.13.0 and com.googlecode.concurrentlinkedhashmap to 1.4.2. Can you try again after git pull?

The issue still open?!
@nmvijay I just import the jena-sparql-api-core-2.10.0-22.jar into my project directly, not update the pom, then set the order lower than maven lib, get both chicken and egg!

I met the same problem, what's 'import the jena-sparql-api-core-2.10.0-22.jar into my project directly'? I tried to import it to a idea project and it still error
