  • 0

When working with ActiveMQ in Eclipse, you might sometimes get a schema parsing error as such: 

Caused by: org.xml.sax.SAXParseException: cvc-complex-type.2.4.c:
The matching wildcard is strict, but no declaration can be found for element 'amq:broker'.

However, the project deploys successfully in Tomcat.

    To fix this, you must associate the ActiveMQ XSD URL with the schema.

    Go to XML->XML Catalog in Preferences, and add a User Specified Entry.

    Location: http://activemq.apache.org/schema/core/activemq-core-5.3.0.xsd
Key Type: Namespace Name
Key: http://activemq.apache.org/schema/core

    Then add a second one:

    Location: http://activemq.apache.org/schema/core/activemq-core-5.3.0.xsd
Key Type: Schema Location
Key: http://activemq.apache.org/schema/core/activemq-core.xsd

    Hit OK.

    If you have this same error and Tomcat fails, open the applicationContext-jms.xml file which triggers the error and replace:

    http://activemq.apache.org/schema/core/activemq-core-5.2.0.xsd

    with

    http://activemq.apache.org/schema/core/activemq-core.xsd
