Unable to locate NamespaceHandler when using context:annotation-config

[raston]

The two threads about "Unable to locate Spring NamespaceHandler" on this fourm have had over 5000 views so this obviously quite a common problem. Is there an issue open for it in JIRA?

Cheers, Rich.

Hey,

I just tested 2.1 installed into a plain Eclipse 3.4 JEE package and can't reproduce this problem.

Are you guys installing Spring IDE's OSGi extension? Please also check if you have more than one spring security bundle in your plugins directory. Please note that the bundle has been renamed from org.springframework.bundle.security.core to org.springframework.security.core. Eventually delete those old bundles.

Furthermore it would be very interesting to get the OSGi bundle status. Please start your Eclipse with "eclipse -console" and post the output of "ss org.springframework" into this thread.

Lets try to solve this problem.

Hi Christian,

Thanks for the reply! I've got a bit closer to solving my problem. Now with a clean Eclipse 3.4 JEE and the new released Spring IDE 2.1 (Core, Security Extension and OSGi Extension) I no longer get the warnings.

(By the way is the OSGi extension required in order for the Security one to work?)

I then tried to get the working with my main Eclipse 3.3 installation. I removed all Spring featuers and plugins and re-installed Spring IDE 2.1 but I am still getting the warnings.

Here is my console output:

osgi> ss org.springframework

As you can see org.springframework.security.core is in there but seems not to be working. Any ideas?

Hi Christian,

Still getting those warnings with new Spring 2.1 IDE installed (no OSGi) on Eclipse 3.4.0:

Unable to locate Spring NamespaceHandler for element 'authentication-manager' of schema namespace 'http://www.springframework.org/schema/security'
Unable to locate Spring NamespaceHandler for element 'authentication-provider' of schema namespace 'http://www.springframework.org/schema/security'
Unable to locate Spring NamespaceHandler for element 'http' of schema namespace 'http://www.springframework.org/schema/security'

Also I've added these lines to my config file:

<authentication-manager alias="authenticationManager" />
  <beans:bean class="org.springframework.security.ui.preauth.j2ee.J2eePreAuthenticatedProcessingFilter">
    <custom-filter position="PRE_AUTH_FILTER" />
    <beans:property name="authenticationManager" ref="authenticationManager" />
...

and I'm getting this warning:

Referenced bean 'authenticationManager' not found

This is the list of Spring IDE files in my plugin directory:
org.springframework.ide.eclipse.security.source_2. 1.0.v200808011800
org.springframework.ide.eclipse.security_2.1.0.v20 0808011800.jar
org.springframework.security.annotation_2.0.4.v200 807280800.jar
org.springframework.security.core_2.0.4.v200807280 800.jar

and features:
org.springframework.ide.eclipse.security.feature.s ource_2.1.0.v200808011800
org.springframework.ide.eclipse.security.feature_2 .1.0.v200808011800

Although Spring IDE reports all these warning my application works correctly.

Thank you,
Vasily

Rich, Vasily,

thanks for the very detailed feedback.

(By the way is the OSGi extension required in order for the Security one to work?)

Yes, the OSGi extension is required but that is not indicated during install or in documentation. Furthermore there is no hard technical reason for this dependency. I created a bug to fix this:

IDE-914: Security plugin should not rely on existence of the OSGi plugin to install NamespaceHandler
http://jira.springframework.org/browse/IDE-914

Can you guys please test the upcoming nightly build. There are no other changes in that build besides this fix for the fore-mentioned bug. So it should be safe to install.

@Rich: I don't have any clue why your Eclipse 3.3 is showing the problems as the bundle status looks just fine. Can you try the upcoming nightly as well please.

Let me know if that helps.

Christian

Hi Christian, Rich, Vasily,

I tried 2.1.1.v200808042008 nightly build and it works fine without namespace warnigs.
BTW, I found no bean in Spring Elements tree in Project Exploler that is declared as security namespace such as <security:http/>. How about yours?

I have a rather hackish workaround for my special problem with maven-assembly-plugin not concatenating spring.handlers and spring.schemas in the generated jar-with-dependencies.

I created those two files manually and put

<fileSet>
	<directory>target/classes</directory>
	<outputDirectory>META-INF</outputDirectory>
	<includes>
		<include>spring.handlers</include>
		<include>spring.schemas</include>
	</includes>
</fileSet>

in my assembly descriptor to put them into META-INF of the final jar. Not a very clean solution, but it works for now.
