Attributes
name
Identifies the parameter to set for the current servlet bean.
value
The value to assign this parameter.
Usage Notes
dsp:oparam
(open parameter) takes the value supplied to it in a JSP and passes it to the current dsp:droplet
tag. Each servlet bean maintains a set of open parameters which the servlet bean can set, service, and deliver as output to a JSP. For information about open parameters that are available for specific servlet beans, see Appendix B, ATG Servlet Beans.
See the HowJSPsHandleServletBeans section in the CreatingandUsingATGServletBeans chapter of the ATG Programming Guide.
Example
<dsp:importbean bean="/atg/dynamo/droplet/Switch"/> <dsp:valueof param="person.name"/>: <dsp:droplet name="Switch"> <dsp:param name="value" param="person.hasCar"/> <dsp:oparam name="false"> No vehicle </dsp:oparam> <dsp:oparam name="true"> Vehicle with capacity of <dsp:valueof param="person.carCapacity"/> </dsp:oparam> </dsp:droplet>
The Switch
servlet bean evaluates the input parameter value
and tests the Boolean result against the open parameters true
and false
. The servlet bean processes the matching open parameter.
