Good morning!

I'm trying to use the the icv http client with a standalone database but I seem to be missing a dependency somewhere because the sample code throws a ClassNotFoundException

Before running mavenInstall.sh I updated openrdf-sesame-2.7.12.jar with the pom and properties from the 2.7.10 jar (after updating the version number in the pom).
I'm using the groupId:artifactId:version from the Stardog documentation (com.complexible.stardog.icv.http:client:2.2).

The specific error is

Exception in thread "main" java.lang.NoClassDefFoundError: com/complexible/barc/ProtocolConstants

My source code and pom are attached.

v/r,
Duane

The class in question is contained in dist/client/snarl/bigpacket-shared-2.2.jar. The imports is wrong in the source, which we will fix for the next version. In the meantime, you might have to manually include that file.

Cheers,

Mike

Thanks, Mike!

Looks like it needed pellet-3.0.2.jar as well. After adding them manually, the program ran fine.
