How to connect standalone desktop application in adobe AIR with spring

[tejaspatel]

Hello friends,

I have been using spring mvc since long time and also I have little knowledge of Adobe Flex action scripting 3. Now I want to develop an application whose client end will be Adobe AIR standalone desktop application and back end will be spring application running on apache tomcat 6.x. I have developed a login screen and written classes and methods for validating user using spring-security.

When I run the application in tomcat I am getting following error:

I have googled a lot, also tried to search previous forums, but i was not able to find any appropriate solution for this.

Any helpful answer or suggestions are appreciated.

Thank you in advanced...

This has been answered before and judging from the stack trace you are mixing spring versions/spring jars. Check your class path for conflicting jars also check in different class loaders for same or multiple spring jars.

Hello Marten,

Thank you for your reply. Please can you tell me for which jar conflicts I should check for, I mean for spring versions or for flex jar files versions? Currently I am using spring 2.5

Spring jars...
