Java class requirements

The generated Java classes must be serializable. The @XmlRootElement element must be specified in the Java classes that represent the schema.

You can use the URL location (-U command) to read and write Java objects only when your objects are serializable. To generate serializable objects, specify <serializable uid="1"/> in a bindings file under <globalBindings> and pass it to the XJC binding compiler with the -b option. For example:
xjc -b bindings.xjb

The -C adapter command points to the root class. You can annotate your root class with the @XmlRootElement, or the XJC binding compiler can do it for you. To use the XJC binding compiler to annotate the root class, add <xjc:simple/> to your bindings file under <globalBindings>. Pass the bindings file to the XJC binding compiler by using the -b option.

An example bindings file follows:
<?xml version="1.0" encoding="UTF-8"?>
<bindings xmlns="http://java.sun.com/xml/ns/jaxb"
          xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance"
          xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
          xsi:schemaLocation="http://java.sun.com/xml/ns/jaxb 
                              http://java.sun.com/xml/ns/jaxb/bindingschema_2_0.xsd"
			                         version="2.1">
  <globalBindings>
    <serializable uid="1" />
	  <xjc:simple/>
  </globalBindings>
</bindings>
The XJC binding compiler produces Java files (.java) from the schema. You manually package the Java files into Java Archive (JAR) files. You must modify the CLASSPATH environment variable for all Java-based adapters that rely on external JAR files. You can edit the CLASSPATH directly, or you can add the JAR files to the config.yaml configuration file. Add JAR file entries to the /runtime/External Jar Files dictionary of the config.yaml file and specify the full path to the JAR file. For example:
External Jar Files:
    jar1: “c:/J2EE/lib/j2ee.jar”
    jar2: “c:/mypath/myjar.jar”
