Andreas, do you have infinispan-persistence-soft-index.jar in the classpath ?
No, I don't.
Do you know where it is available? I can't find it in infinispan-7.1.1.Final-all.zip unfortunately, nor do I see it in the cache store download website.
Ah, you're right, I'll try to get it on the website. You can use Maven with coordinates
You can use this command to download it to current directory:
mvn org.apache.maven.plugins:maven-dependency-plugin:2.8:get -Dartifact=org.infinispan:infinispan-persistence-soft-index:7.1.1.Final -Dtransitive=false -Ddest=.
Cool! All I was missing was the jar file on the classpath. Thanks a lot!
