Spring 3.0: "El prefijo" X "para el atributo" Y "asociado con un elemento tipo" Z "no está vinculado"

Question

Mi aplicación funcionaba bien hasta esta mañana pero empecé a recibir los errores a continuación después de renombrar mi Netbeans 6.9 proyecto esta mañana.

Estoy recibiendo el siguiente error en la construcción de mi primavera 3.0.4 aplicación:

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

applicationContext.xml:

ver nada mal aquí?

Answer 1

No tengo ninguna experiencia con Netbeans, pero supongo que el problema podría estar relacionado con el esquema XML para el espacio de nombres p.

Es una suposición descabellada, pero déjame tomarlo. Tal vez había configurado Netbeans para agregar un XSD personalizado a su catálogo y señaló el archivo XSD dentro de su proyecto. Después de cambiar el nombre del proyecto, la ruta al esquema XML del espacio de nombres p no es válida.

Ni siquiera sé si dicha configuración de catálogo XML es posible en Netbeans, estoy más interesado en Eclipse. Pero lo verificaría en tu lugar.

Answer 2

Sé que llego tarde, pero tengo el mismo error y puede ser que esto es muy útil a los demás .. pongo el

p:something 

en

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

Así, en lugar de

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

prueba esto:

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

Answer 3

Necesita agregar espacios de nombres a su declaración de beans.
