My destination beans are getting destroyed after start up

[bram_bba]

Hi,

I made a spring, flex, spring security project based on the testdrive examples.

spring 2.5.6, spring-security-core-tiger 2.0.4, spring-flex 1.0.1.RELEASE.

On my mac, deploying the war in tomcat, works perfectly.
I can log in, log out, persist some orders,...

But it on windows, my destinations beans are destroyed just after creation. The war is still deployed. I can still access the swf, but as my channels are closed. I can't do anything.

Please help me, I'm losing to much time with this and I really don't know where to look.

Can you post you web.xml, flex-servlet.xml and any thing else they are touching?

Ok, so the first thing I would try is to make a "flex" folder at the same level as the flex-servlet.xml. Then put the services-config.xml in it. You should not need to reference it in the flex-servlet.xml.

Also try adding all the other channels to the services-config.xml and see if you still get the problem.

I don't see any flex:RemotingDestinations in your flex-servlet. And where are you declaring your "destination beans" that you can't access? You can put those in the flex-servlet too.

I would also put the hibernate stuff that is in the services-context, in it's own file and then import it into the flex-servlet, or you can just put it in there directly.

You may want to try the whole thing without Security first and then turn on security after it works. As for Security don't forget to set the "Connector SSLEnabled" in the tomcat server.xml in your windows machine.

Just some ideas, let us know how it goes.

If your destination beans are getting destroyed, you must be getting an error and a stack trace somewhere. The stack trace would greatly help in pinpointing your problem.

[bram_bba]

Issue resolved.

For some kind of weird reason, tomcat deployed my war twice.

Thanks to Joshua to try help me out.

[vijaych1209]

Hello bram_bba, Similar thing is happening with me and my app is getting redeployed in tomcat after session time out.
Could you tell me how did you resolve this issue, or stop tomcat redeploying the app after session expires. Thanks
