Hello,
I am creating a plugin for Nutch that extends the QueryFilter.
I get a successful compilation with "ant" and "ant war", but when I do a
search, I get the following exception:
26/11/2008 18:50:07 org.apache.catalina.core.StandardWrapperValve invoke

The DecoderException class is in commons-codec-1.3.jar, so I added the jar
file to my plugin.xml:
<runtime>
<!-- As defined in build.xml this plugin will end up bundled as
recommended.jar -->
<library name="personalized-search.jar">
<export name="*"/>
</library>
<library name="commons-codec-1.3.jar" />
</runtime>
But the same error appears. Any idea on what I may be doing wrong?
Thanks.
