beans vs beans:beans namespace?

[giantsteps]

Hi -

I've created my project from the sprint templates available in sts. These templates include a servlet-context.xml that declares the beans namespace as beans:beans rather than just plain beans.

On the other hand, the root-context is just plain beans and most of the project examples I see or download use just plain beans. I have xsd problems if I try to change it to plain beans.

Can anyone explain what is going on? Thanks.

Hi Peter,

depending on the template you select, it will be the default name space used in the servlet-context.xml

For instance, if you select the spring-mvc template, then you'll get the next:

<beans:beans xmlns="http://www.springframework.org/schema/mvc"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:beans="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
		http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

Please note the default name space is that of mvc. Therefore you may just start adding <validator>, <resources>, and so on.

In case you want beans to be default, then you need to change both the xmlns, remove the beans and add the mvc, like this:

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
		http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

Hope it helps.

Carlos.

These templates include a servlet-context.xml that declares the beans namespace as beans:beans rather than just plain beans.

This means the default namespace is not "beans", it is something else (i.e mvc, security)

I have xsd problems if I try to change it to plain beans.

How a look at following example,

Default is "security"

<beans:beans xmlns="http://www.springframework.org/schema/security"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:beans="http://www.springframework.org/schema/beans"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.0.3.xsd">


	<authentication-manager alias="authenticationManager">
		<authentication-provider>
			<user-service>
				<user name="admin" password="admin" authorities="ROLE_ADMIN" />
				<user name="user" password="user" authorities="ROLE_USER" />
			</user-service>
		</authentication-provider>
	</authentication-manager>
</beans:beans>

Converted to "beans"

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:security="http://www.springframework.org/schema/security"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.0.3.xsd">


	<security:authentication-manager alias="authenticationManager">
		<security:authentication-provider>
			<security:user-service>
				<security:user name="admin" password="admin" authorities="ROLE_ADMIN" />
				<security:user name="user" password="user" authorities="ROLE_USER" />
			</security:user-service>
		</security:authentication-provider>
	</security:authentication-manager>
</beans>

According to example, if you have a lot of security related code, it is easier when the security namespace is the default.

Ah and now I see the light... This was really tripping me up as I'm pretty new. Thanks.
