Experiments not running locally #246

Hi,

I'm trying to run Gerbil (1.2.6) but it is not working in a local environment. When I want to see the progress of the experiment, I got the following error:

GRAVE: Servlet.service() for servlet [dispatcher] in context with path [/gerbil] threw exception [Handler processing failed; nested exception is java.lang.NoClassDefFoundError: com/hp/hpl/jena/rdf/model/impl/IO_Ctl] with root cause java.lang.ClassNotFoundException: com.hp.hpl.jena.rdf.model.impl.IO_Ctl at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1702) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1547) at com.github.jsonldjava.jena.JenaJSONLD.init(JenaJSONLD.java:135) at com.github.jsonldjava.jena.JenaJSONLD.<clinit>(JenaJSONLD.java:121) at org.aksw.gerbil.dataid.DataIDGenerator.createDataIDModel(DataIDGenerator.java:86) at org.aksw.gerbil.web.MainController.experiment(MainController.java:210) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497)

Likewise if the page is refreshed, the error changes to: org.springframework.web.util.NestedServletException: Handler processing failed; nested exception is java.lang.NoClassDefFoundError: Could not initialize class com.github.jsonldjava.jena.JenaJSONLD org.springframework.web.servlet.DispatcherServlet.triggerAfterCompletionWithError(DispatcherServlet.java:1275) org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:951) org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:867)

Does Jena 3.1 supports such missing class? Moreover, Gerbil 1.2.5 does not send requests in a web service annotator experiment (although the testing communication works fine).

Hope yo can help me

Thanks, José

com/hp/hpl/jena/rdf/model/impl/IO_Ctl is from Jena 2.X not 3.X. The JSON-LD library which we use is based upon 2.X. I'll try to figure a way out.

TortugaAttack commented 6 years ago

Okay, the 2.x needed the dependency to create JSON-LD, which if i understood correctly is now implemented in 3.x itself. I'll check this somewhen today and let you know and push the changes if it works :)

TortugaAttack commented 6 years ago

done, should be working (works for me) please check again, and if it worked close the issue :)

Hey thank you, I tested this last version and seems to work fine. However, it takes a while before the first execution starts. Tested on MacOS 10.10.5 and Ubuntu 16.04

Thank you
