Hi Robert/Howard
I am trying to run T3 and T5 pages with in the same application. Here I have a
problem when I try to call T5 page from T3 page.
Please let me know my approach is correct or not? My exact requirement is as
explained below:
I have one JavaScript function like this:
function onSymAutoProjectConfig(){
location.href = "/app/tapestry5";
location.href.submit();
}
In web.xml I have the code like this:
<context-param>
<param-name>tapestry.app-package</param-name>
<param-value>com.example.tapestry5</param-value>
</context-param>
<filter>
<filter-name>app</filter-name>
<filter-class>org.apache.tapestry5.TapestryFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>app</filter-name>
<url-pattern>/app/*</url-pattern>
</filter-mapping>
---
Followed by T3 filters and servlets
I have written Index.tml and Index.java pages under the package
com.example.tapestry5. When I call the javascript onSymAutoProjectConfig()
function. The Index.tml is not getting invoked.
I guess the problem here is I am not able to invoke the TapestryFilter. And
also please let me know whether we can run T5 and T3 filters in the same
application? Please suggest the correct approach for me.
Thanks & Regards

I would suggest creating a simple application in T5 first, to get the feel for
setting up web.xml and getting all the libraries straightened out.
Once you've done that, you can use the injected Request object to read and
write session attributes, or use the @SessionAttribute annotation on a field
(on the T5 side).
On the T3 side, you'll need to do a bit more work to get the
HttpServletRequest, to read and write session attributes. I believe you should
look at the IEngine interface as a starting point, but my memory of all that is
pretty weak.
Basically, the HttpSession becomes a kind of "mailbox" that the T5 and the
other app can use to communicate and share state. It doesn't matter if the
other app is T3 or Struts or pure servlets.
