Cannot using * to setProperty

Question

I found that if the bean properties contain any short data type.
This coding does'nt work in JSP....
<jsp:setProperty name="awbpaymentInfo" property="*" />
This setProperty * can also work on the bean contains int, float, boolean, long, string.
Error message as below:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Compilation of 'E:\work\cargo\root\WEB-INF\_tmp_war_JalCargoAdminServer_JalCargoAdminServer_cargo\jsp_servlet\_awbpayment\_processaction.java' failed:
E:\work\cargo\root\WEB-INF\_tmp_war_JalCargoAdminServer_JalCargoAdminServer_cargo\jsp_servlet\_awbpayment\_processaction.java:204: setPayType(short) in javabeans.AWBPaymentInfo cannot be applied to ()
probably occurred due to an error in /AWBPayment/ProcessAction.jsp line 14:
<jsp:setProperty name="awbpaymentInfo"property="*" />
Full compiler error(s):
E:\work\cargo\root\WEB-INF\_tmp_war_JalCargoAdminServer_JalCargoAdminServer_cargo\jsp_servlet\_awbpayment\_processaction.java:204: setPayType(short) in javabeans.AWBPaymentInfo cannot be applied to (<null>)
awbpaymentInfo.setPayType(null); //[ /AWBPayment/ProcessAction.jsp; Line: 14]
^
1 error
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In bean - AWBPaymentInfo.java
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
private short payType;
public void setPayType(short aPayType) {
payType = aPayType;
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
BUT if i use this coding, it works .....
<jsp:setProperty name="awbpaymentInfo" property="payType" />
Does it means that there is a bug in somewhere ?
I'm using JDK1.3 and WebLogic as application server.
Any help ? Thanks
Cheers, May

Hi,
the approach I usually use when working with beans and JSP is to make all the setters parameters as String, to be sure that there won't be any error made during settings.
So, the thing that you can for example is
class YourClass {
private payType;
// constructor
YourClass(){}
public void setPayType(String aPayType) {
try {
   payType = Short.parseShort(aPayType);
} catch (Exception e) {
   // default value
}I hope this helps
