Hi Rupert, When I load localhost:8080/engines it says this:
There are currently 5 active engines. org.apache.stanbol.enhancer.engines.metaxa.MetaxaEngine org.apache.stanbol.enhancer.engines.langid.LangIdEnhancementEngine org.apache.stanbol.enhancer.engines.opennlp.impl.NamedEntityExtractionEnhanc ementEngine org.apache.stanbol.enhancer.engines.entitytagging.impl.NamedEntityTaggingEng ine org.apache.stanbol.enhancer.engines.entitytagging.impl.NamedEntityTaggingEng ine Maybe this could tell you something?

The best description I found was on http://weblogs.java.net/blog/binod/archive/2006/12/glassfish_and_w.html About the enhancement result you posted: This is what the result looks like if only the Metaxa and the LangId Engine are active. So I assume that the other engines where not activated correctly. Maybe because of the IOException Can you please check if you use a Firewall that could cause this? Are you running Stanbol on Windos? best Rupert On 11.01.2012, at 19:46, Srecko Joksimovic wrote: > Hi Rupert, > > I configured Stanbol, and I thought everything is alright because I could > access Stanbol at http://localhost:8080. > But, I noticed that during the startup I'm getting this error: > > [WARNING] failed org.mortbay.jetty.nio.SelectChannelConnector$1@29978933: > java.i > o.IOException: Unable to establish loopback connection > [WARNING] failed [email protected]:8080: java.io.IOException: > Unabl > e to establish loopback connection > [WARNING] failed Server@62d844a9: java.io.IOException: Unable to establish > loopb > ack connection > [ERROR] Exception while initializing Jetty. > java.io.IOException: Unable to establish loopback connection > at sun.nio.ch.PipeImpl$Initializer.run(Unknown Source) > at java.security.AccessController.doPrivileged(Native Method) > at sun.nio.ch.PipeImpl.<init>(Unknown Source) > at sun.nio.ch.SelectorProviderImpl.openPipe(Unknown Source) > at java.nio.channels.Pipe.open(Unknown Source) > at sun.nio.ch.WindowsSelectorImpl.<init>(Unknown Source) > at sun.nio.ch.WindowsSelectorProvider.openSelector(Unknown Source) > at java.nio.channels.Selector.open(Unknown Source) > at > org.mortbay.io.nio.SelectorManager$SelectSet.<init>(SelectorManager.j > ava:312) > at > org.mortbay.io.nio.SelectorManager.doStart(SelectorManager.java:223) > at > org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java: > 50) > at > org.mortbay.jetty.nio.SelectChannelConnector.doStart(SelectChannelCon > nector.java:314) > at > org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java: > 50) > at org.mortbay.jetty.Server.doStart(Server.java:235) > at > org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java: > 50) > at > org.apache.felix.http.jetty.internal.JettyService.initializeJetty(Jet > tyService.java:164) > at > org.apache.felix.http.jetty.internal.JettyService.startJetty(JettySer > vice.java:115) > at > org.apache.felix.http.jetty.internal.JettyService.run(JettyService.ja > va:290) > at java.lang.Thread.run(Unknown Source) > Caused by: java.nio.channels.ClosedByInterruptException > at java.nio.channels.spi.AbstractInterruptibleChannel.end(Unknown > Source > ) > at sun.nio.ch.SocketChannelImpl.connect(Unknown Source) > at java.nio.channels.SocketChannel.open(Unknown Source) > ... 19 more > > There is another thing.
