NetConnection.Call.Failed happening sporadically in Flex3/Tomcat/BlazeDS/Spring

阅读更多关于 NetConnection.Call.Failed happening sporadically in Flex3/Tomcat/BlazeDS/Spring

问题 I have a very large problem. I've written a large app using Flex3/Tomcat/BlazeDS/Spring that has worked very well while developing locally, fine when I deployed to a common dev environment, but then fails very often when deployed to our test environment. The failures seem to happen most when a remoting request takes a good bit of time (more than 20 seconds). On my dev server, the errors happen, but only when the request takes a very long time (more than 45 seconds). However, the error also

问题 I take data from Java to Flex by AMF (BlazeDS) In java side object has Integer field. So it can be null. In Flex side object is int. So null values are deserialized as 0. This is not what I want, I want to see whether it is 0 or null. Is there wrapper like (Integer in Java) for Flex? Thanks 回答1: As far as I can tell, there is no such wrapper. You can write one that assigns NaN to the internal int if the argument to the constructor is null 回答2: We solved this by creating a BeanProxy class

How does [RemoteClass] work in Flex Actionscript can I use it for custom data-binding?

阅读更多关于 How does [RemoteClass] work in Flex Actionscript can I use it for custom data-binding?

问题 Actionscript supports a [RemoteClass] metadata tag that is used in BlazeDS to provide data-binding hints for marshalling AMF binary objects from Java to BlazeDS. For example: Java: package sample; public class UserInfo { private String userName; public String getUserName() { return userName; } public void setUserName(String value) { userName = value; } } Actionscript: [Bindable] [RemoteClass(alias="sample.UserInfo")] public class UserInfo { public var userName:String=”"; } How exactly is the

Any Flex 4 migration experience?

阅读更多关于 Any Flex 4 migration experience?

My current development stack is MySQL + iBatis + Spring + Spring BlazeDS Integration 1.01 + BlazeDS 3.2 and Flex 3 with Mate 0.8.9 framework. Now Flash Builder 4 beta 2 is out. There are cool features like Data Centric Development (DCD), form generation etc... Do you know how Spring Blazeds Integration works with BlazeDS 4? What about Mate? Is there any issues with Flex 4 ? How DCD suits with mate eventmaps. I know it is better to try it out myself but I just want to check if somebody ever tried to migrate Flex 4. If so what are the issues? Did you notice any productivity speed up? Thanks.

Duplicate Flex Sessions With Cross-Domain Requests

阅读更多关于 Duplicate Flex Sessions With Cross-Domain Requests

问题 When I make a request locally, I have no problems at all maintaining my FlexSession; however, when I make a request from another computer, it creates duplicate FlexSession for every request. I noticed the JSESSIONID is different for each request which is what's probably causing the duped sessions. But I have no idea why this is happening. The specific error I get is: Channel.Ping.Failed error Detected duplicate HTTP-based FlexSessions, generally due to the remote host disabling session
