Hello List,
I try to enable the spellchecker in my 1.4.0 solr (running with tomcat 6 on
debian).
But I always get the following exception, when I try to open
http://localhost:8080/spell?xxxx:
HTTP Status 500 - null java.lang.NullPointerException at

My Configuration looks like this:
solrconfig.xml
<searchComponent name="spellcheck" class="solr.SpellCheckComponent">
<str name="queryAnalyzerFieldType">textSpell</str>
<lst name="spellchecker">
<str name="name">a_spell</str>
<str name="field">a_spell</str>
<str name="buildOnOptimze">true</str>
<str name="buildOnCommit">false</str>
<str name="spellcheckIndexDir">./spellchecker</str>
</lst>
</searchComponent>
<requestHandler name="/spell" class="solr.SearchHandler" lazy="true">
<lst name="defaults">
<!-- omp = Only More Popular -->
<str name="spellcheck.onlyMorePopular">false</str>
<!-- exr = Extended Results -->
<str name="spellcheck.extendedResults">false</str>
<!-- The number of suggestions to return -->
<str name="spellcheck.count">1</str>
</lst>
<arr name="last-components">
<str>spellcheck</str>
</arr>
</requestHandler>
schema.xml
<fieldType name="textSpell" class="solr.TextField" positionIncrementGap="100"

</analyzer>
<analyzer type="query">

<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt"/>
<filter class="solr.StandardFilterFactory"/>
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</analyzer>
</fieldType>
......
<field name="a_spell" type="textSpell" />
I don't know what's wrong with the given configuration and the exception not
really clear ;)
Can somebody give me a hint? Thank you in anticipation.
Best regards,
Rafael.
