Deprecated.

As of Dynamo 5.5, use BeanProperty instead. BeanProperty is identical in functionality to BeanPropertyServlet, but more correctly named, and provides a BeanInfo class for the DCC.

public class BeanPropertyServlet
extends DynamoServlet

This servlet gets or sets a property in a bean. The bean is defined by the bean parameter. The property to get or set is defined by the propertyName parameter. The value may be set or read using the propertyValue parameter. In either case, the droplet renders an oparam named output.

Examples:

To set the property value, specify the new value using the propertyValue parameter, as in this example:

 <droplet bean="/atg/dynamo/droplet/BeanPropertyServlet">
   <param name="bean" value="param:myBean">
   <param name="propertyName" value="color">
   <param name="propertyValue" value="red">
 </droplet>
 

When setting property values the oparam need not be used, since there's no need to render output within the droplet's context.

To get the property value, leave the propertyValue parameter unset. The parameter will then take on the current value within the output oparam, as in this example:

 <droplet bean="/atg/dynamo/droplet/BeanPropertyServlet">
   <param name="bean" value="param:myBean">
   <param name="propertyName" value="color">
   <oparam name="output">
     The bean's color is <valueof param="propertyValue">unset</valueof>.
   </oparam>
 </droplet>
 

Dotted subproperty expressions of the form "a.b.c" are permitted when getting a property value, though not when setting one. When getting a value using subproperty expressions, if any intermediate property is null then propertyValue will also be null, as is the case when using DynamicBeans.

pResponse - the servlet's response

Throws:

javax.servlet.ServletException - if there was an error while executing the code

java.io.IOException - if there was an error with servlet io

serviceGet

protected void serviceGet(DynamoHttpServletRequest pRequest,
                          DynamoHttpServletResponse pResponse,
