Problem

With Spring OXM + Castor binding, the Castor library is added, but still hit the following error message?

Exception in thread "main" java.lang.RuntimeException: 
	Could not instantiate serializer org.apache.xml.serialize.XMLSerializer: 
	java.lang.ClassNotFoundException: org.apache.xml.serialize.XMLSerializer
	at org.exolab.castor.xml.XercesSerializer.<init>(XercesSerializer.java:50)
	//...

Castor dependency in Maven.

	<dependency>
		<groupId>org.codehaus.castor</groupId>
		<artifactId>castor</artifactId>
		<version>1.2</version>
	</dependency>

Solution

If not mistake, Castor need Xerces to work, so, you need to add Xerces dependency also.

	<dependencies>

		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-oxm</artifactId>
			<version>3.0.5.RELEASE</version>
		</dependency>

		<dependency>
			<groupId>org.codehaus.castor</groupId>
			<artifactId>castor</artifactId>
			<version>1.2</version>
		</dependency>

		<dependency>
			<groupId>xerces</groupId>
			<artifactId>xercesImpl</artifactId>
			<version>2.8.1</version>
		</dependency>

	</dependencies>
