Tika runs in the > higher class level. Its expectation is that classes that are loaded via > reflection use the classloader associated with the class that is resolving > the reflection, NOT the thread classloader. That's standard Java practice. > But apparently there's a place where Tika doesn't do it that way: > {code} > Error tossed: org/apache/poi/POIXMLTextExtractor > java.lang.NoClassDefFoundError: org/apache/poi/POIXMLTextExtractor > at > org.apache.tika.parser.microsoft.ooxml.OOXMLParser.parse(OOXMLParser.java:106) > ~[?:?] > at > org.apache.tika.parser.CompositeParser.parse(CompositeParser.java:280) ~[?:?] > at > org.apache.tika.parser.CompositeParser.parse(CompositeParser.java:280) ~[?:?] > at > org.apache.tika.parser.AutoDetectParser.parse(AutoDetectParser.java:143) > ~[?:?] > at > org.apache.manifoldcf.agents.transformation.tika.TikaParser.parse(TikaParser.java:74) > ~[?:?] > {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
