You have to define the Crystal Reports servlet in your web.xml file, along
with a mapping for it (making sure that you maintain the required order of
elements in this file):
<servlet>
<servlet-name>Crystal Reports Viewer</servlet-name>
<servlet-class>com.foo.bar.crystal.CrystalViewer>
</servlet>
<servlet-mapping>
<servlet-name>Crystal Reports Viewer</servlet-name>
</url-pattern>/crystal</url-pattern>
</servlet-mapping>
and then your parameter value in the Action would be "/crystal" (the
context relative path to the viewer servlet.
