Problem upgrading from M2 to RC1

[jettro]

I am having some problems with the upgrade path to RC1. I have changed the version of the blazeds integration to RC1. I had to add the org.codehaus.jackson/jackson-core-asl dependency and change the flex:remote-service into flex:remoting-destination. I also use the service-id, which I had to change into destination-id. (Wrong in the documentation by the way).

Now I am starting the application and I am receiving the following message. Does someone have a clue what I need to change as well?

seems like it might be an issue with the springsecurity settings, but not sure yet

[jlawmi]

If you turn off session fixation it will go away. Since i'm in dev this is ok for now:

<http auto-config="false" entry-point-ref="preAuthenticatedEntryPoint" session-fixation-protection="none">


FWIW, I tried what is suggested in the source code, but it didn't fix the prob:

if (filterList == null) {
log.warn("Spring Security filter chain could not be found. You must install the RequestContextFilter or RequestContextListener"
+ "manually in order for the flex session fixation protection integration to function as expected.");
return;
}

You are absolutely right, that did the trick. Strange message for this problem, does seem like a bug to me. Did you already file this as a bug?

I also use the service-id, which I had to change into destination-id. (Wrong in the documentation by the way).

Thanks for pointing it out...captured as http://jira.springframework.org/browse/FLEX-45.

You're right, it is definitely a bug...just created http://jira.springframework.org/browse/FLEX-46 to capture it. Fix will be committed shortly and I'll fire off a snapshot build so that you guys can test it out if you like...I'll update here when it's ready.

[jeremyg484]

FLEX-46 is fixed. You should be able to run with the session fixation protection enabled now. The fix is available in build 148 (or later). http://s3.amazonaws.com/dist.springframework.org/snapshot/FLEX/spring-flex-1.0.0.CI-148.zip

Is this a bug? This comes with default configuration. Were are using RC1 and Maven tomcat plugin.

Is this a bug? This comes with default configuration. Were are using RC1 and Maven tomcat plugin.

We added Jackson as a new dependency, but it looks like it got marked as optional in the maven POM:


<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>com.springsource.org.codehaus.jackson</artifactId>
<version>0.9.9.4</version>
<optional>true</optional>
</dependency>

even though it is actually required.

I've created http://jira.springframework.org/browse/FLEX-47 to correct this for 1.0. In the meantime, you'll have to add it manually.

Thanks for quick response :)

[DrPedro]

thanks for the hint to migrate to RC1:

Another hint for people migrating from M2 to RC1, you may have to change your flex code that handle the login result event.

I was using the following code


// Handle successful login.
private function LoginResultEvent(event:ResultEvent, token:Object=null):void
{

switch (event.result)
{
case "success":
Alert.show("Login OK: ");
dispatcher.dispatchEvent(new LoginEvent(LoginEvent.LOGIN_SUCCESSFUL));
break;
default:
}
}

which does not work anymore in RC1 since user details are now returned by the server upon login
Extracted from reference documentation here is a code that works


var token:AsyncToken = myChannelSet.login("jeremy","atlanta");
token.addResponder(
new AsyncResponder(
function(event:ResultEvent, token:Object = null):void {
if (event.result.authorities.indexOf("ROLE_ADMIN") >= 0) {
displayAdminPanel(event.result.name);
} else {
displayUserPanel(event.result.name);
}
},
function(event:FaultEvent, token:Object = null):void {
displayErrorMessage("Login Failed: "+event.fault.faultString);
}
)
);



BTW Thanks for the RC1, I can't wait testing the messaging feature!

You should also add it to the documentation section "What Spring BlazeDS Integration requires to run". It would have helped me a bit :-P

[maheshrox]

Hi everybody

I am a flex developer and struggling with my first flex spring integration example. I went through many links including the one suggested in this discussion but nothing seems giving me a solution. i am using spring-flex-1.0.1.RELEASE, is this problem related to the this spring-blazeDS integartion release ? In most of the examples they have been using Maven which i doesnt know about it.

Could anybody in this forum give me an insight about how to get out of this error ?
