unable to integrate my dao classes with spring

[Satish Jhaldiyal]

Dear all,

I have DAO classes and i am doing something like


<context:component-scan base-package="com.pgi.em.dataaccess"/>

in my springs-bean.xml.

This particular line is giving me the following error

org.springframework.beans.factory.BeanDefinitionStoreException: Line 15 in XML d
ocument from ServletContext resource [/WEB-INF/classes/spring-beans.xml] is inva
lid; nested exception is org.xml.sax.SAXParseException: Element type "context:co
mponent-scan" must be declared.
Caused by:
org.xml.sax.SAXParseException: Element type "context:component-scan" must be dec
lared.
at org.apache.xerces.util.ErrorHandlerWrapper.createSAXParseException(Un
known Source)
at org.apache.xerces.util.ErrorHandlerWrapper.error(Unknown Source)



Can anybody please throw some light and let me know the possible remedy. Any help would be appreciated.

Thanks,
satish

Did you correctly declare the namespace ?

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

Please help. I am stuck with this problem from past few days.
I have searched a lot but of no use. I even tried using spring xsd version 3.

Thanks.

Please don't resurrect old threads. Create a new thread with your question. I am going to close this thread.

Thanks

Your pom includes two versions of Spring.

Remove

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring</artifactId>
<version>2.0</version>
</dependency>

Also component-scan automatically includes context:annotation-config.
