Error: no declaration can be found for element 'prop'. At servlet-context.xml

[Ramon Bonet]

Hello community. I'm a newbie Spring user developing my first Spring MVC application.

The following code, located at servlet-context.xml:

<beans:bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
		<beans:property	name="dataSource" ref="dataSource"/>
		<beans:property name="packagesToScan" value="cat.tfcproject.springmvc.domain"/>
		<beans:property	name="hibernateProperties">
			<props>
				<prop	key="dialect">org.hibernate.dialect.HSQLDialect</prop>
			</props>
		</beans:property>
</beans:bean>

Gives me this error:

The matching wildcard is strict, but no declaration can be found for element 'props'

The same error occurred with <bean> element, but it was fixed including 'beans' prefix <beans:bean ..>

My two questions are: How can I fix the 'props' element error? and How can I avoid using 'beans' prefix in every <bean> xml declaration?

Just to mention that I already has the 'bean' xmlns and schema-location declarations, like this:

...
xmlns:beans="http://www.springframework.org/schema/beans"
...
xsi:schemaLocation= ...
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

And if I write the schema location like this, instead of previous delcaration:

http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd

In booth cases if I don't put the 'beans' prefix, like this

<bean id="... 
...
</bean>

I have the same error:

The matching wildcard is strict, but no declaration can be found for element 'bean'.
Cannot locate BeanDefinitionParser for element [bean]

Very thankful for your help

1) xmlns:beans="http://www.springframework.org/schema/beans"

That is where you yourself set the "prefix" to "beans"

if it was

xmlns="http://www.springframework.org/schema/beans"

Then you won't need the prefix.

<props> is also part of the beans namespace, so it would need <beans:props> too if you keep the prefix.

Thanks Mark, understood. All depends if there is a prefix defined at namespaces delcaration or not, you have to include the prefix in all declarations below or not.

But the fact is I already have one 'xmlns' declaration without prefix included among others. Take a look:

<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"
	xmlns:jee="http://www.springframework.org/schema/jee"
	xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
		http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
		http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee.xsd">

I'm not able to write more than one xmlns values without prefix, only once. The rest have to include a ':'prefix.

Is there any way to write multiple xmlsn-non-prefix values?


Pd: note I write the initial bean declaration of servlet-context.xml with the 'beans' prefix, because this is how bean namespace is defined right now

Thanks

No, you can only have one. Which I now see you have for the <mvc> namespace. So which do you use more in that file? tags from the mvc namespace, or tags from the beans namespace. Whichever you use more, that should be the no prefix one you want to use.

Okay, so I guess I'll use no-prefix for <mv> name space. Thank you very much!
