Hi Andriy, all
sending this again to the list as others might be affected/interested
as well. Especially Suat as he is currently fighting an very similar
issue in the CMS adapter
The assumption that Tika may miss XML Beans is wrong as Tika includes
xmlbeans 2.3.
java.lang.NoClassDefFoundError: Could not initialize class
org.apache.xmlbeans.XmlBeans
Errors like that indicate that during the initialization of a Class.
This includes the initialization of static variables (or static
blocks) in the mentioned class and all super classes. Looking at the
source of XmlBeans shows that in this case nearly everything is called
during static initialization :(
However when it comes to external dependencies there are only two and
in that context only the dependency to
javax.xml.stream.XMLStreamReader seams relevant.
javax.xml.stream.XMLStreamReader is part of the "stax-api". This API
is included in JDK 1.6. Stanbol imports the stax-api twice
1. via the JDK because the Stanbol frameworkfragment lists all the
packages of the stax-api
2. via the
org.apache.servicemix.specs:org.apache.servicemix.specs.stax-api-1.0:2.1.0
This could indeed cause the error you are expiriencing. I have created
a launcher with a preliminary fix for that. You can find it under [1].
Can you please try if this solves your issue.
Please use "-Xmx1024m -XX:MaxPermSize=256M" when staring the full launcher
best
Rupert
