Java Schema

The Java Schema shared configuration resource allows you to specify a Java class that is used to configure a Java To XML or XML To Java activity.

The Java class is converted to an XML schema using the following rules:

•

Only the public data members of the Java class are mapped to XML elements. Private and protected members are not included.

•

The Java class member public variable name is mapped to an XML element with the same name. For example, a Java class member variable declared as public int ZipCode is mapped to an XML element named ZipCode.

•

Java Bean accessors and modifiers are mapped to appropriate XML element names. For example, a Java class method public int getBalance() or public void setBalance(int Balance) are mapped to an XML element named Balance.

•

Only one XML element is created regardless of how many members of the Java class share the same name. For example, there may be an attribute named MySalary and accessors named getMySalary() and setMySalary(). This translates to one element named MySalary in the resulting XML document.

•

Conversion is case-sensitive. For example, if you have a data member declared as public int zipCode and an accessor method declared public void setZipCode(int NewZipCode), there will be two elements in the resulting XML schema, zipCode (for the data member) and ZipCode (for the accessor). You must make sure to use the correct element when using the resulting XML in input mappings of subsequent activities.

•

All Java primitive types are supported. Datatypes that extend java.util.Collections are also supported (for example, List, ArrayList, andVectors). Arrays (for example, int[] and string[]) are also supported.

•

The datatype java.util.Map or any types that extend java.util.Map are not supported. For example, HashMap is not supported.

Configuration

The Configuration tab has the following fields.


Field	Description
Name	The name to appear as the label for the resource.
Description	Short description of the shared resource.
Java	This field contains the Library and Class fields that allow you to specify the Java class for this resource.
Library	Use this field to specify an AliasLibrary resource that is used to locate the Java class files. See TIBCO Designer Palette Reference for more information about AliasLibrary resources.
Class	The Java class that specifies the data of the schema. This class must implement or be a subtype of a class that implements the Serializable interface. You can use the Show Class Browser button to browse Java classes in the TIBCO ActiveMatrix BusinessWorks classpath.
Schema Namespace	The namespace to use for the schema when converting to or from XML.

Schema Text

The Schema Text tab displays the resulting XML schema from the Java class selected on the Configuration tab.
