JPO for Getting Field Values

• Field Type=program
• program=JPO name
• function=JPO method name

For processing the data, the input parameter can be used by the method. The return type of this method is a StringList, which contains one or more field value to be displayed.

Here is a template for this kind of JPO method:

public static Object methodName(Context context, String[] args) 
throws Exception

{

HashMap programMap = (HashMap) JPO.unpackArgs(args);

HashMap requestMap = (HashMap) programMap.get("requestMap");

HashMap paramMap = (HashMap) programMap.get("paramMap");

String  objectId = (String) requestMap.get("objectId"); 

String  relId = (String) paramMap.get("relId"); 

String  languageStr = (String) requestMap.get("languageStr"); 

// initialize the return variable

    StringList fieldValues = new StringList();

// define and add selects if required

    // Process the information to obtain the values

    if ( objectId != null)

    {

    //add the field values

    fieldValues.addElement(?);

}

    return fieldValues;

}
