Interface sunw.io.Serializable Error

Question

Hi all,
I am using Jdeveloper 10.1.3.3.0.3 and keep receiving the following error in my Control File when running my page:
"Error(71,41): incompatible types; found: class java.lang.String, required: interface sunw.io.Serializable."
Control File:
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
super.processFormRequest(pageContext, webBean);
if (pageContext.getParameter("HzPuiGoSearch") != null)
String CustomerNumber = pageContext.getParameter("HzPuiCustomerNumber");
OAApplicationModule am = pageContext.getApplicationModule(webBean);
Serializable[] parameters = { CustomerNumber }; //Error Line
am.invokeMethod("executeQuery", parameters);
AMimpl File:
public void executeQuery(String CustomerNumber)
OAViewObject vod = (OAViewObject)getxxarSiteSearchVO1();
vod.setWhereClauseParam(0, CustomerNumber);
vod.executeQuery();
Thanks in advanced!

Answer 1

1- Make sure to include "java.io.Serializable" as part of yoru import block
2- Change the following line
FROM
Serializable[] parameters = { CustomerNumber}
TO
Serializable[] parameters = new Serializable[] { CustomerNumber}
HTH,
