XML to Java is a synchronous activity. Use this activity to create an instance of a Java object based on data from an XML document. The XML schema for providing the input to the Java object or Java schema specified on the
General tab of this activity.
General
The specified Java class must meet the following requirements:
- The Java class must have a public default constructor (that is, a constructor with no arguments).
- The Java class must be eligible to be serialized (that is, the class must implement or be a subclass of a class that implements
java.io.Serializable).
If the class does not have a public data member and only has a Java bean accessor that retrieves the data, the input schema contains an element for the accessor. However, the resulting Java object has no value set for the member. For example, the object has a method declared as public int
getID(), but there is no method for setting the ID and the data member ID is not public. In this case, an element named ID in this activity’s input schema, but mapping a value to the element does not result in setting the ID member of the output Java object. This is because there is no public mechanism for setting the data.
The
