I've identified a critical bug when downloading JDBC drivers for DBRE. For those affected, please download a build snapshot from here

Sorry for this inconvenience

Thanks for your patience.

Congrats on ROO 1.2.0.M1. It sure is an awesome product... the enhancements around repository / DAO layer instead of the default Roo JPA 'Active Record'-based persistence approach.. is much appreciated.

Now to the issue:

version:spring-roo-1.2.0.M1
OS: Windows XP
Java : jdk1.6.0_25

I am sure you may not have come across this issue... much of the 'corporate' (social media blocked ones) world would not be able to use it 1.2.0.M1 or the latest build cause of this code in:
Class - org.springframework.roo.shell.jline.osgi.JLineShel lComponent
// Access Twitter's REST API
String string = sendGetRequest("http://api.twitter.com/1/favorites.json", "id=SpringRoo&count=5");


This is the Error that I get, whenever I start up ROO

Welcome to Spring Roo. For assistance press TAB or type "hint" then hit ENTER.
Exception in thread "Spring Roo JLine Shell" java.lang.NullPointerException
at org.springframework.roo.shell.jline.osgi.JLineShel lComponent.getLatestFavouriteTweet(JLineShel
lComponent.java:97)

at java.lang.Thread.run(Thread.java:662)

Temporary Solution:
Disable Wireless/Network and start ROO, then enable Wireless/Network

Thanks,
Reggie

I raised https://jira.springsource.org/browse/ROO-2847 and committed some code, but before that, I was unable to reproduce the issue. I just added a couple of null checks so please get the latest Roo snapshot from http://static.springsource.org/downl...hp?project=ROO.

Please note there have been changes to the Roo annotations, so existing projects will be broken until you rename the annotations, so I suggest testing with a new project directory.

Alan, I really appreciate you filing an issue. The issue ROO-2847 comment does not have the real problem, which is the call to Twitter API.

I just wanted to make you aware that the code ROO 1.2.0.M1 and the Latest build works fine for me from home or outside my work Network. The issue is that ROO will not start up and give the error, because of the call to the twitter api.

The issue is in org.springframework.roo.shell.jline.osgi.JLineShel lComponent
on line 86 String string = sendGetRequest("http://api.twitter.com/1/favorites.json", "id=SpringRoo&count=1"); it makes a call to twitter API.
Twitter (Facebook, ... most social site) is blocked in most traditional corporations, so cause of the call to http://api.twitter.com in JLine... ROO will not start up, and gives error.

But say, I disconnect (or disable) the Wireless/Network at work, the code works fine, since the call to Twitter will fail (a 404 kind...). If I am behind a corporate Network (Twitter blocked) then it is not really 404... This Monday, our company plans to open up access to Twitter, and hence I may not get this error, but I am sure someone else will run into this, and it may not be apparent to them the reason of the error.

Thanking you,
Reggie

I turned off my network access completely but still don't get the issue. Can you please attach the full stack trace of what you see? The sendGetRequest method is probably throwing the exception, but as I have just arrived in San Francisco on my way to Chicago for SpringOne, I've got somewhat limited network access (and time) at the moment to do some more testing.

[alexanrb]

You are right, if you turn off your network, it will work fine.

Who does this issue affect?
ONLY users whose access to "Twitter.com" is BLOCKED, this is mostly in Corporate offices.

How can a regular user test it?
You need "Twitter.com" blocked by a firewall, or network.

What happens after the error?
The ROO console/shell just hangs

Which version of ROO, does this happen?
All 1.2 version (M1 and any Builds)

Is there a work around?
Yes, switch OFF your network, start ROO, then once you get the prompt, switch ON your network connection.

[Alan Stewart]

Would you please try the latest snapshot (6e4ef8c) to see if it solves the issue?

[alexanrb]

Alan, it is really awesome that you have provided a fix so quickly, and that it could make it to the build.

Extremely sorry, our company just opened up Twitter.com and cause of this I do not have the needed (blocked) Network setup to test this scenario :-(
