Hi,

I would like to use the excellent urlrewrite module in my app – it looks great for separating the user experience of URLs and my systems architecture. http://www.tuckey.org/urlrewrite/

My re-write rule is expressed like this:
<rule>
<from>/explore</from>
<to>/home?p=742</to>
</rule>

The log of the resulting crash is below. What does “no session or session was closed” mean? What is causing that?

The line of my code in that lot is here:

$Proxy35.getContent(Unknown Source)
c013.web.prop_controller.home(prop_controller.java:94)

where line 94 of prop_controler is
result = result + cataloguesService.getContent(catalogue, breadcrumb);
i.e. a call on the scafoldeded Service to get some records.

I dont like the look of the $Proxy35, let alone the “Unknown Source” that follows.

The app works fine when urlrewrite is not triggered.

Could this error be caused because urlrewrite is trapping the URL and then not processing to the correct myEclipse Spring approach?

Regards

ok, solved this – you have to use type=”redirect” which presumably forces the url to be processed from the top again, rahter than from within url rewrite, which sets up the session correctly. Wish I knew enough to know how that works.

So it should be
<rule>
<from>/explore</from>
<to type=”redirect”>/home?p=742</to>
</rule>

Thanks for posting the issue and resolution, this will certainly help others.
