18.6. Configuring iText
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>
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.
<components xmlns="http://jboss.com/products/seam/components"
xmlns:document="http://jboss.com/products/seam/document"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

http://jboss.com/products/seam/components

<document:document-store use-extensions="true"/>
</components>
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.
<document:document-store use-extensions="true"
error-page="/documentMissing.seam" />
