Using TopBraid SHACL API with Jena TDB

[Felix Sasaki]

Hi all,

I am trying to use the SHACL API with Jena TDB. 

This CreateWriteRead file

https://github.com/henrietteharmse/henrietteharmse/tree/master/blog/tutorial/jena/source/tdb/src/main/java/org/jena/tdb/tutorial

works with the POM file at

https://github.com/henrietteharmse/henrietteharmse/tree/master/blog/tutorial/jena/source

if I try to use TDB with shacl by adding a dependency

<dependency>

<groupId>org.topbraid</groupId>

<artifactId>shacl</artifactId>

<version>1.0.1</version>

</dependency>

The POM build fails I get an error:

java.lang.NoClassDefFoundError: org/apache/jena/sparql/core/TransactionHandlerView

Are there any suggestions how to combine the SHACL API with Jena TDB?

Regards

Felix

Have you tried increasing the <version> number to the current release 1.4.2?

If your POM includes Jena, it must be the same version that is used by the TopBraid SHACL API.

For TopBraid SHACL API 1.4.2, this would be Jena 4.3.2 (not 3.7.0 as you have it below).

For other versions of the API, you can check https://mvnrepository.com/artifact/org.topbraid/shacl . Select the API version you're interested in, then scroll down to the Compile Dependencies section and look for “org.apache.jena » jena-arq” and its version.

Hope that helps,

Richard

That works, thanks a lot, Richard!
