ClassNotFoundException: org.springframework.flex.config.xml.FlexNamespaceH andler

[jaggernat]

hi guys

I am using spring blazeds integration 1.5.0.M1 with spring 3.0

This is my flex servlet

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:flex="http://www.springframework.org/schema/flex"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schem...-beans-3.0.xsd
http://www.springframework.org/schema/flex
http://www.springframework.org/schema/flex/spring-flex-1.0.xsd">

<flex:message-broker>
<flex:message-service
default-channels="my-streaming-amf,my-longpolling-amf,my-polling-amf" />
<flex:secured />
</flex:message-broker>
....and so on..


I have spring-flex-core-1.5.0.M1-sources.jar and spring-integration-core-1.0.3.RELEASE.jar in my classpath. (do i need anything else?)

when my server starts i get this error on the above flex servlet

org.springframework.beans.factory.BeanDefinitionSt oreException: Unexpected exception parsing XML document from ServletContext resource [/WEB-INF/flex-servlet.xml];

nested exception is org.springframework.beans.FatalBeanException: NamespaceHandler class [org.springframework.flex.config.xml.FlexNamespaceH andler] for namespace [http://www.springframework.org/schema/flex] not found;
nested exception is java.lang.ClassNotFoundException: org.springframework.flex.config.xml.FlexNamespaceH andler
at org.springframework.beans.factory.xml.XmlBeanDefin itionReader.doLoadBeanDefinitions(XmlBeanDefinitio nReader.java:412)

am i missing something?

Thanks

I have spring-flex-core-1.5.0.M1-sources.jar and spring-integration-core-1.0.3.RELEASE.jar in my classpath. (do i need anything else?)

This error always indicates that either you don't have the spring-flex library on the classpath, or you've got multiple versions of it on the classpath.

Why do you have the -sources jar in your classpath? That doesn't belong there. It should just be spring-flex-core-1.5.0.M1.jar

[jaggernat]

Thanks for the reply.

I added the spring-flex-core-1.5.0.M1.jar and (removed the sources jar)

But now i get
org.springframework.beans.FatalBeanException: Required type class not found; nested exception is java.lang.ClassNotFoundException: flex.messaging.config.ConfigMap
at org.springframework.beans.factory.config.CustomEdi torConfigurer.postProcessBeanFactory(CustomEditorC onfigurer.java:214)

any thing i should look for?

thanks

Seems like you are missing the blazeds-common jar

[jaggernat]

got the blazeds commons jar and now i get
>>NoClassDefFoundError: flex.messaging.security.LoginCommand

any other jars needed?
thanks

[jaggernat]

added blazeds-core-3.0.jar and solved that problem.
Is there any place where developers can locate all the jars at once rather than hunting around for dependencies.

thanks.

[jaggernat]

i get the java.lang.NoClassDefFoundError: flex.messaging.AbstractFlexSessionProvider

any idea?
thanks

[amiladomingo]

Are you using blaze ds 3 or 4. AbstractFlexSessionProvider is a class that came with blazeds 4.

[jaggernat]

i am using blazeds 4

[jaggernat]

ok my bad, i should not have had blazeds-core-3.0 and blazeds-comon-3.0
since i am using blazeds 4. so i made the changes,this is what i have so far

flex-messaging-common.jar (ver 4)
flex-messaging-core.jar (ver 4)
flex-messaging-remoting.jar (ver 4)
spring-flex-core.jar (ver 1.5.0.M1)
spring-integration-core.jar (ver 1.0.3)

and the errror i get now is >>>ClassNotFoundException: org.springframework.security.web.authentication.se ssion.SessionFixationProtectionStrategy

I am using spring security 3.0 aswell (with spring 3.0)
I googled around for the SessionFixationProtectionStrategy
error and found that others have also had issue with this when using with spring security.

I am finding the solution, if anyone already knows the solution i will appreciate if you can please share it.

thanks.
