Thanks Rupert and Fabian for your responses. Hi Rupert,
Thanks for suggesting workarounds. We have tried all three workarounds but the issue persists. I am sure i am missing something, if you can please review below findings will help us identify gaps in our approach. * * *"1. reduce the size of the configuration (e.g. by removing comment lines from the field mappings)"* We are configuring EntityHubLinking engine and we dont see any comments as it is present while configuring ReferenceSite. *"2. configure the Site using the configuration file located in "stanbol/fileinstall". Make sure that changes to the file confirm to the syntax required by the *.config files" * We tried configuring EntityHubLinking engine by editing "* org.apache.stanbol.enhancer.engines.entityhublinking.EntityhubLinkingEngine.org.apache.stanbol.enhancer.engines.entityhublinking.EntityhubLinkingEngine.f7141185-9fe8-4ab9-ad05-fa4988399694 .config" *file located under "*stanbol/fileinstall*" folder. We added fields value under "*enhancer.engines.linking.dereferenceFields*"* *property. But this didn't result in we getting more information for additional fields in derefrenced entities. Do i need to restart stanbol server after editing *.config files ? The catch here is on our OS, felix configurations doesnt persist after restarting stanbol. *"3. running Stanbol as WAR within a Tomcat. In Tomcat you can configure the headerBufferSize like explained in [3]" * We added stanbol.war to tomcat, however it is throwing an exception on opening Felix console.
