Hi Ben,
i think this won't work since the plainDocFactory will only be used for
files of type "plain" but not for files of type "binary".
Recently we have done some additions to the module - by order of Lenord,
Bauer & Co. GmbH - that could meet your needs. It introduces a more flexible
way of defining docFactories that you can add new factories without having
to recompile the whole module. So other modules (like the news) can bring
their own docFactory and all you have to do is to edit the registry.xml.
Here is an example:
<docFactories>
<docFactory enabled="true" type="plain">
<fileType name="plaintext">
<extension>.txt</extension>
<class>net.grcomputing.opencms.search.lucene.PlainDocument</class>
</fileType>
</docFactory>
<docFactory enabled="true" type="news">
<class>net.grcomputing.opencms.search.lucene.NewsDocument</class>
</docFactory>
</docFactories>
To index binary files all you need to add is this:
<docFactory enabled="true" type="binary">
<class>net.grcomputing.opencms.search.lucene.BodylessDocument</class>
</docFactory>
There should be no need for an extension mapping.
For the interested people:
For ContentDefinitions (like news) i introduced the following:
<contentDefinitions>
<contentDefinition type="news"> <!-- must match docFactory
type -->
<class>com.opencms.modules.homepage.news.NewsContentDefinition</class>
<initClass>net.grcomputing.opencms.search.lucene.NewsInitialization</initCla
ss>
<listMethod name="getNewsList">
<param type="java.lang.Integer">1</param>
<param type="java.lang.String">-1</param>
</listMethod>
<page uri="/news.html?__element=entry">
<param method="getIntId" name="newsid"/>
</page>
</contentDefinition>
In short:
initClass is optional: For the news the news classes have to be loaded to
initialize the db pool.
listMethod: a method of the content definition class that returns a List of
elements
page: the page that can display an entry. Here a jsp that has a template
element "entry". It also needs the id of the news item.
getIntId is a method of the content definition class and newsid is the url
parameter the page needs. A link like
news.html?__element=entry&newsid=xy
will be generated.
Best regards,
Stephan
