in your new class CustomIndexingFilter, create a field Configuration
conf, and implement setConf, getConf like this:
public void setConf(Configuration conf) {
this.conf = conf;
}
public Configuration getConf() {
return this.conf;
}
and pass the conf object to RegexURLFilterBase before calling it.
RegexURLFilterBase r = new RegexURLFilter();
r.setConf(conf);
r.filter("sometext");
This should do the trick.
I assume you have setup the build configuration of your plugin
correctly, was tricky for me ;-)
build.xml
<!-- Build compilation dependencies -->
<target name="deps-jar">
......
<ant target="jar" inheritall="false" dir="../urlfilter-regex"/>
<ant target="jar" inheritall="false" dir="../lib-regex-filter"/>
</target>
<!-- Add compilation dependencies to classpath -->
<path id="plugin.deps">
<fileset dir="${nutch.root}/build">
.......
<include name="**/urlfilter-regex/*.jar" />
<include name="**/lib-regex-filter/*.jar" />
</fileset>
</path>
and plugin.xml
<requires>
<import plugin="nutch-extensionpoints"/>
......
<import plugin="urlfilter-regex"/>
<import plugin="lib-regex-filter"/>
</requires>
HTH,
