Java To XML

Note: If the class does not have a public data member and only has a Java bean modifier that sets the data, the input schema contains an element for the modifier, but the resulting XML document has no value set for the corresponding element. For example, the Java object has a method declared as public int setID(), but there is no method for getting the ID and the data member ID is not public. In this case, an element named ID in this activity’s output schema exists, but that element has no value because there is no public mechanism for getting the data.

General

Description

Provide a short description for the Java to XML activity.

Advanced

The Advanced tab has the following fields.

Field	Description
Instantiate the referenced class	This field controls one of the following: The referenced class must be constructed when the activity is executed. An object reference must be supplied in the activity’s input schema. Select this check box to construct the referenced class using the default constructor when the activity executes. In this case, the referenced class is not included in the activity’s input schema. Do not select this check box if you want to provide an object reference for the class name specified on the General tab. The object must be created and contained in the output schema of a previously executed activity. In this case, the referenced class is included in the activity’s input schema.
Cache the object	This option is available only when you select the Instantiate the referenced class check box. Select this check box to specify that all instances of this Java Invoke activity share the instance of the instantiated referenced class. A cached referenced object is kept in the memory until the process engine terminates. Not selecting this check box leads to each instance of this Java To XML activity creating its own copy of the referenced class.

Field

Description

Instantiate the referenced class

This field controls one of the following:

The referenced class must be constructed when the activity is executed.
An object reference must be supplied in the activity’s input schema.

Select this check box to construct the referenced class using the default constructor when the activity executes. In this case, the referenced class is not included in the activity’s input schema.

Do not select this check box if you want to provide an object reference for the class name specified on the General tab. The object must be created and contained in the output schema of a previously executed activity.

In this case, the referenced class is included in the activity’s input schema.

Cache the object

This option is available only when you select the Instantiate the referenced class check box.

Select this check box to specify that all instances of this Java Invoke activity share the instance of the instantiated referenced class. A cached referenced object is kept in the memory until the process engine terminates.

Not selecting this check box leads to each instance of this Java To XML activity creating its own copy of the referenced class.

Input

The following is the input for the activity.

Input item	Datatype	Description
referenced class	Java Object	An object reference to the Class Name specified on the General tab. This element is only available when the Instantiate the referenced class check box is clear on the Advanced tab.

Output

The following is the output of the activity.

Output Item	Datatype	Description
XML Schema	varies	The output is the XML schema from the converted Java object. The elements in the schema display in alphabetical order.

Fault

The Fault tab lists the possible exceptions generated by this activity.

Fault	Generated When..
`JavaToXMLConversionException`	An error occurred when converting the Java object to XML.
