How to use beehive with J2EE filter ?
Hi all,
How to use Beehive with J2EE filter ?
My JSPs generates XML that is processed by a filter to be transformed in
HTML. My web.xml is as:
<filter>
<filter-name>XSLT</filter-name>
<filter-class>xxxxxxxxxxxxxxx</filter-class>
</filter>
<filter-mapping>
<filter-name>XSLT</filter-name>
<url-pattern>/html/*</url-pattern>
</filter-mapping>
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.beehive.netui.pageflow.PageFlowActionServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.jpf</url-pattern>
</servlet-mapping>
My controller is "jpf/main/Controller.jpf"
When I call: http://<server:port/context/html/jpf/main/Controller.jpf, I
have org.apache.struts.action.RequestProcessor : Invalid path
/html/jpf/main/Controller was requested in traces.
Regards,
Christophe

Hi Christophe,
Yes, the NetUI maps the servlet path portion of the URI, as the module path
for the Controller. The "/html" prefix to the servlet path causes the
behavior you identified. However, one solution would be to implement a
wrapper (extend HttpServletRequestWrapper) for the request and override the
methods that return servlet path, request URI/URL, etc. Your wrapper will
strip the "/html" from the URI. Then the page flow internals will not see
this as part of the request and should be OK. After the chain.doFilter()
call returns, your filter can do the transformation as desired.
There is one issue you should be aware of... if your JSP use the NetUI tag
library to write URIs in the response, they would not include the /html
prefix. You may not be using the tags, depending on the XML you are writing,
and the majority of the NetUI tags map to and generate HTML tag output. But
if you are, the URIs would be incorrect for your final response. During the
page flow processing, NetUI just sees your request wrapper and has no idea
about your "/html" format prefix in the URI of the real request. For
example, if you use the NetUI anchor tag to produce <a href="...">...</a>,
the href attribute would not include the "/html" prefix.
To solve this you could role your own stuff in your filter to process the
URIs when you translate the response, but a better solution would be to
extend the NetUI URLRewriter and register it with the URLRewriterService.
Then, during the NetUI tag processing for rendering your JSP, the NetUI tags
would pass a mutable URI object into your rewriter implementation and you
could add the desired path prefix. Your filter would register your rewriter
with the URLRewriterService before calling chain.doFilter(). The NetUI API
Javadoc describes the methods to override on the URLRewriter class and the
register methods on the service.
http://beehive.apache.org/docs/1.0.1/netui/apidocs/javadoc/index.html
Hope this helps. Kind regards,
Carlin

Antony,
Your suggestion changes anything.
I think that the PageFlowActionServlet use the full path of the URL to
find the controller or the action to execute.
How can I remove "/html" from the path before PageFlowActionServlet ?
