Using the OpenCms Lucene Search Module generate, create pdf 417 none with .net projects Barcode FAQs file contains PDF-417 2d barcode for .NET no markup and is just plain text. However, if it encounters myfile.

xml, it will match the .xml extension to the file type taggedtext, so it will use the net.grcomputing.

TaggedPlainDocument class to process the file. The TaggedPlainDocument class assumes that the file contains HTML or XML tags and ignores all the tags when indexing the file. The OpenCms Lucene module also supports indexing of a couple of binary types, notably Adobe PDF and MS Word documents.

Here"s a sample configuration for indexing these two formats:. <docFactor y enabled="true" type="binary"> <fileType name="PDF"> <extension>.pdf</extension> <class> net.grcomputing.

PDFDocument </class> </fileType> <fileType name="Word"> <extension>.doc</extension> <class> net.grcomputing.

WordDocument </class> </fileType> </docFactory>. Similar to th VS .NET PDF 417 e plain document factory, this will check the extensions of any documents of type binary. If the extension is .

pdf, the file will be indexed by the PDFDocument class. Likewise, if the extension is .doc, then WordDocument will be used.

In the preceding example registry, both JSP and XML template document factories are disabled. Generally, this is a good idea. The OpenCms Lucene module operates on the files in the CMS.

It makes no attempt to render JSP or XML template files before indexing (the assumption being that these files are dynamic, and hence should not be indexed). If enabled, the document factories for these types will simply strip out all the JSP or XML tags and then index the remaining text, and this is not very useful. Along with the core types defined in OpenCms, Lucene can index any document that has a content definition (see 5).

In the example you just saw, document factories exist for both news and forum types. Both these utilize custom content definitions, and for that reason, both require entries in the <contentDefinitions/> section..

Content Definitions The <conte VS .NET pdf417 2d barcode ntDefinitions/> section provides the OpenCms Lucene module with the information necessary to instantiate and access content of types defined in custom content definitions. Here is an example for the content definition of the popular "News" module:.

<contentDefinition type="news"> <class> Appendix B </class> ; <initClass> net.grcomputing.opencms.

search.lucene.NewsInitialization </initClass> <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 the <co visual .net PDF417 ntentDefinition/> element, the type attribute defines which type is being defined (note that this should match up with the type attribute of the <docFactory/> element). <class/> indicates the class that extends com.


The <initClass/> element specifies a class that can initialize an instance of the content defined in the <class/> element. The news module, for instance, requires an <initClass/> to initialize its database connection pool. Other modules, like the forum module, do not need any particular initialization before the indexer runs.

If you create a module that needs initialization before it can be indexed by Lucene, you will need to create an initialization class that implements. The <listM .net framework PDF417 ethod/> element defines how the module should get a list of resources of the given type (often, content for modules is handled by an API other than simply using com.opencms.

file.CmsObject). The name attribute contains the name of the method to call on the class specified in <class/>.

This method should return a java.util.List object.

The <param/> elements define the Java object type (type="java.lang.String") and value for the parameters required by the <listMethod/>.

Here"s the <listMethod/> section from the preceding example:. <listMetho d name="getNewsList"> <param type="java.lang.Integer">1</param> <param type="java.

lang.String">-1</param> </listMethod>. This translat pdf417 for .NET es to the following code:. newsInstance. getNewsList( new Integer( 1 ), new String( "-1" ) );. The <page/ Visual Studio .NET pdf417 2d barcode > element is used to construct the URL that the OpenCms Lucene module will use to refer to the object. It also takes one or more <param/> elements that define how to get identifiers (method="getIntId") and then the names it should use to append the identifiers to the arguments list of the uri.

In the case just discussed, if the "news" content definition getIntId() method returned 1234, the indexer would generate the link /news.html __element=entry&newsid=1234..
