Document generation itself requires no additional configuration, but some minor configuration can make your application more user-friendly.
The default implementation serves PDF documents from a generic URL, /seam-doc.seam. Many users prefer to see a URL that contains the actual document name and extension — /myDocument.pdf, for example. To serve fully named files, the DocumentStoreServlet must contain mappings for each document type:
<servlet>
<servlet-name>Document Store Servlet</servlet-name>
<servlet-class>
org.jboss.seam.document.DocumentStoreServlet
</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Document Store Servlet</servlet-name>
<url-pattern>DOCUMENT_TYPE</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>Document Store Servlet</servlet-name>
<servlet-class>
org.jboss.seam.document.DocumentStoreServlet
</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Document Store Servlet</servlet-name>
<url-pattern>DOCUMENT_TYPE</url-pattern>
</servlet-mapping>

DOCUMENT_TYPE can take on the following values:
*.pdf
*.xls
*.csv
To include multiple document types, add a <servlet-mapping> element, with <servlet-name> and <url-pattern> sub-elements, for each desired document type.
The use-extensions option instructs the DocumentStore component to generate URLs with the correct filename extension for the generated document type.

The DocumentStore holds documents in conversation scope, so documents will expire when the conversation ends. At that point, references to the document will be invalid. Specify a default view to show when a document does not exist by editing the error-page property of documentStore.
