Spring 3.0: "The prefix" X "for attribute" Y "associated with an element type" Z "is not bound"

My app was working fine until this morning but I started getting the errors below after I renamed my Netbeans 6.9 project this morning.

I'm getting the following error when building my Spring 3.0.4 app:

The prefix "p" for attribute "p:driverClassName" associated with an element type "beans:bean" is not bound

See anything wrong here?

You need to add namespaces to your beans declaration.

xmlns:c="http://www.springframework.org/schema/c" xmlns:p="http://www.springframework.org/schema/p"

See the spring documentation reference.

http://docs.spring.io/spring/docs/3.2.x/spring-framework-reference/html/beans.html#beans-p-namespace

---

I don't have any experience with Netbeans, but I guess the problem might be related to XML schema for the p namespace.

It's a wild guess, but let me take it. Maybe you had configured Netbeans to add a custom XSD to its catalog and pointed to the XSD file within your project. After you renamed the project, the path to p namespace XML schema is invalid.

I don't even know if such XML catalog configuration is possible in Netbeans, I am more into Eclipse. But I would check that in your place.

I know i am late but i got same error and may be this is usefull to others.. i put the

p:something 

into

<property name="something" value="anything_you_want_to_set"/>

So, instead of

p:driverClassName="net.sourceforge.jtds.jdbc.Driver"

try this :

<bean>
    <property name="driverClassName" value="net.sourceforge.jtds.jdbc.Driver" />
    <!-- and your others property -->
</bean>
