What I need to do is construct a form that has a variety of text input forms on it that are determined at run-time. I know how to do this in jsp but I need to provide an ActionForm that conforms to that form. I got several useful replies last night and am investigating them.

Maybe something like:
<pre>
public class DynamicActionFormFactory {
/** This method is used to configure and create a new empty dynamic
* action form based on the parameters provided.
*
* @param name the registered name of the form
* @param type the name of the Java class of the form
* @param fields a list of the field names to be used in the form
* @return the modified String */
public static ActionForm createBlankForm(String name, String type, String[] fields) {
ActionForm form = null;
FormBeanConfig config = null;
FormPropertyConfig prop = null;
config = new FormBeanConfig();
config.setName(name);
config.setType(type); if (fields != null) {
for (int i=0; i<fields.length; i++) {
prop = new FormPropertyConfig();
prop.setName(fields[i]);
prop.setType("java.lang.String");
prop.setInitial("");
prop.freeze();
config.addFormPropertyConfig(prop);
}
}config.freeze();
try {
form = (ActionForm) DynaActionFormClass.createDynaActionFormClass(config).newInstance();
} catch (Exception e) {
StdOut.log("log.error",new ChainedException(e,"Exception creating blank form: " + e.getMessage()));
}
return form; } } </pre>
