Flex Addon for Spring Roo

[marcello.marques]

Hello !

I am trying to test the Flex addon for Spring Roo and it doesn't work. I did all as suggested in "Spring BlazeDS Integration Reference Guide - Chapter 8. Working with the Flex Addon for Spring Roo" and it fell ok, I managed to deploy in the TC Server Developer Edition v2.0, but when I am trying to acess in Firefox received this error:

javax.servlet.ServletException: Circular view path [index]: would dispatch back to the current handler URL [/rootunes/app/index] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)

I saw the webserver log and have this message:

[BlazeDS]No login command was found for 'SpringSource tc Server runtime/6.0.25.A'. Please ensure that the login-command tag has the correct server attribute value, or use 'all' to use the login command regardless of the server.

My services-config.xml is that way:

Can anyone help me ?

Thanks,

I have changed the urlrewrite.xml file

I have changed the RULE
<from casesensitive="false">/</from>
<to last="true" type="forward">/app/index</to>


<from casesensitive="false">/</from>
<to last="true" type="forward">/<your_app_name>_scaffold.html</to>


I am new to this java-flex world. I just fixed by trail and error method, so correct me if i am wrong

I am also facing the same error message. I followed the instructions from Jeremy's screen cast for Roo Flex Addon.

The only thing I did different was that I made the following change in urlrewrite.xml to get rid of an error this xml was throwing.

<!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 3.0//EN" "http://tuckey.org/res/dtds/urlrewrite3.0.dtd">

<!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 3.2//EN" "http://tuckey.org/res/dtds/urlrewrite3.2.dtd">

@aseembehl The error you mentioned is because of cache problem, this can be solved by removing the cache of the url from preferences->general->network connection->cache and validating the urlrewrite.xml until getting good copy of the DTD file.

But marcello.marques question is related circular path <appln>/app/index while running the application in the server. My earlier post method solved this problem. But need know is it right of solving it.

@janakg

Your solution works for me too. Thanks!

Changed the following rule:

<rule>
	<from>/</from>
	<to last="true">/app/index</to>		
</rule>

<rule>
	<from>/</from>
	<to last="true">/<your_app_name>_scaffold.html</to>		
</rule>
