Flex Addon for Spring Roo - Compatibility Update

[MikeOliverAZ]

I did as you said, no difference still getting the "circular view" error.

So I did a clean install of STS 2.5.2, then did the same ROO script as in the getting started part 2 link above, and it worked fine.

Then I installed the flex addon .225 into fhe roo bundle and did the following ROO script and then Run on Server...

field number attending --type java.lang.Integer
field string specialRequests --sizeMax 100
field date confirmed --type java.util.Date
test integration
flex remoting all --package ~.service


The error was ...

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

This was an absolute clean 2.5.2 install in a new directory with a new workspace nothing from before. ROO by itself worked fine on the Wedding example, the same ROO Script plus the two flex lines was the same.

The FlexWebbing application I created with ROO above, now won't run because "Resource out of sync with the filesystem, ...FlexWebbing_scaffold.swf"

About to quit for the day, and hope I will get a clue in the morning when I get up.

Hi Mike-

Sorry for just now responding, but did you have any more luck with this today? If not, I was wondering if you could try and run a very small .roo script from the Roo shell for me. If it doesn't work then there's something else we're missing.

So first, download the attached 'flexroo.roo' script somewhere and in the same location create a directory called 'flexroo'. Then, 'cd' into the 'flexroo' dir. and (I'm sure you know this) run the script by typing the following in the Roo shell:

script --file ../flexroo.roo

Let me know what your results are and let's see what we find.


Thanks,

Thomas

Thomas,

Thanks for your assistance.

I downloaded the zip and created a folder and ran it in the folder as suggested.

That folder with the output of the roo script is at http://dl.dropbox.com/u/249163/STS/flexrooProj.zip

A screen shot of the cmd window is attached. It appeared to work as advertised. The resulting pom is attached.

roo.log...

Then I did

perform eclipse

and imported the project into STS 2.5.2

Then Run on Server...

Feb 23, 2011 7:21:26 AM org.apache.catalina.core.ApplicationDispatcher invoke
SEVERE: Servlet.service() for servlet flexroo threw exception

I might add that the Flex BlazeDS testDrive is working on that same STS.

[MikeOliverAZ]

I also tried running from command line with mvn tomcat:run and it started fine but the error it threw when I hit http://localhost:8080/flexroo was exactly the same circular view error above.

[ArjunSol]

Try http://localhost:8080/flexroo/flexroo_scaffold.html

Your src\main\webapp directory is the application root.

[MikeOliverAZ]

Thanks, I tried running the flexroo_scaffold.html with Run As-> Ron on Server, before, so I created an index.html with the link anchor as you suggested.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<!-- saved from url=(0014)about:internet -->
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">	
    
    <head>
        <title>flexroo</title>          
    </head>
    <body>
        <a href="http://localhost:8080/flexroo/flexroo_scaffold.html" target="_blank" rel="nofollow">http://localhost:8080/flexroo/flexroo_scaffold.html</a>
   </body>
</html>

The index.html comes up as expected on http://localhost:8080/flexroo/

But clicking the link throws the same error...

Feb 24, 2011 7:49:25 AM org.apache.catalina.core.StandardHostValve custom
SEVERE: Exception Processing ErrorPage[errorCode=404, location=/resourceNotFound]

	at org.springframework.web.servlet.view.AbstractView.render(AbstractView.java:250)

So something else is wrong.

Here is the roo.log...

Then I opened /src/main/webapp/FlexWedding_scaffold.html and did a save as index.html.

Then Run on Server and bingo Flex application running AOK

I did notice that in FlexWedding/html-template/ there is a file called index.template.html that is exactly the same as FlexWedding_scaffold.html, so I could have copied that into src/main/webapp/ and renamed that index.html, which by the names must have been indended.

So I am guessing the Flex addon is missing that step that takes index.template.html and copies it and renames it so the applicatoin will run without this much effort.

Of course now that I know, I can do it myself, and I hope this thread helps others avoid the confusion.

[MikeOliverAZ]

I left out one important step to Success.

This last time, I had installed the Flash Builder 4 Plugin into STS 2.5.2 before trying it again.

I want back to the plain STS 2.5.2 and tried it again, and even after copy and rename from FlexWedding_scaffold.html to index.html, I still got the Circular View Error.

So it was installing Flash Builder 4 in my case coupled to the copy to index.html that fixed it for me.

for anyone who's interested I've managed to run this from command line, here are the details
