Error on Spring Surf Tutorial Example

[and_guevara]

Hi,

I just wanted to point out two errors on the sample on the Spring Surf Developer Tools Tutorial.

On this page: http://www.springsurf.org/sites/1.0....ginning-step-8

the file newsfeed.get.js line 17 should be:
var re = /<[r|R][s|S]{2}/; // Is this really an RSS document?

and the file newsfeed.get.html.ftl line 4 should be:
<#if items?exists && (items?size > 0)>

Also the Rss Feed is not returning the expected rss format, it will work better with other Rss Feeds like the one from bbc, substituting in newsfeed.get.js line 2
var newsServiceUrl = "http://fxfeeds.mozilla.com/en-US/firefox/headlines.xml";

Regards,

Andres

This error should have been fixed in M3.

Thanks!

Hi..
I am following the same tutorial which you had posted here. Until the step 2.3.6, there is no issue...

As you reported, I corrected those three issues..
But still when I am trying with http://localhost:8080/surf/page/news/feed, I am getting error in the browser.

Environment details:
Os: Windows Xp
SST version: 2.3.2
roo version: 1.0.2

The error in browser is:
The Web Script /surf/page/news/feed has responded with a status of 500 - Internal Error.

500 Description: An error inside the HTTP server which prevented it from fulfilling the request.

Did you use the JS template here from its download link?

http://www.springsurf.org/sites/1.0....ewsfeed.get.js

Thanks for your quick response...


even after having the js file which you have said, I am getting the same error..
Is there any issue with the html file.

I am having
<div class="dashlet">
<div class="title" > ${title}</div>
<div class="body scrollableList">
<#if items?exists && (items?size > 0)>
<#list items as item>
<div style="clear:both;"><a href="item.link">${item.title}</a></div>
<div style="clear:both;">${item.description}</div>
</#list>
</#if>
</div><#-- end of body -->
</div><#-- end of dashlet -->


But I think, this js is not retrieving the correct feeds...

Hi,

I just created a clean Surf web app and added the newsfeed webscript from the download links. And then started jetty and open browser and test following link

http://localhost:8180/service/news/feed

It works as expected.

The error is from your JS template so it has nothing to do with the freemarker template.

Hi..
You are running the application in jetty server..
I am using tomcat to run the application. I can view my surf sample page in http://localhost:8080/community/

I am following http://www.springsurf.org/sites/1.0....beginning.html

As you said I had changed my js file and now I am getting some new error in browser. When I tried with jetty server, the same below error is displayed.

Exception

Can you say whats the reason for this new error?

Hi,

It looks like you are using M2. Please use M3.

Yong

[kamal_1]

Hi..
Thanks...
When I am using 1.0.0.CI-SNAPSHOT, I am not getting the above error. Can I know what is the difference between these M2, M3 and 1.0.0.CI-SNAPSHOT addons..

Thanks...

[yqu]

From the link you posted, it seems like you are following M2 Tutorial.

You should follow following link

http://www.springsurf.org/sites/1.0....tml/index.html

I have tested Surf M3 on STS 2.3.2 and I tested it on Spring TC server (Tomcat). It seems to work fine.

The only extra thing I did is touching the urlrewirte.xml (Just added a space and saved it).

For now, please use M3.
