Summary: Bean property getter not found when using EL expression
Product: Tomcat 6
Version: 6.0.18
Platform: PC
OS/Version: Windows Vista
Status: NEW
Severity: regression
Priority: P2
Component: Jasper
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
The EL expression ${myBean.xKey} does not yield a call to myBean.getXKey().
However, ${myBean.XKey} does.
Dear All,
I was investigating this bug last night (Philippine time) and found out
something interesting which left me bewildered.
I was trying to come up with a proposed fix. :-)
I have the ff files:
a) testpckg.MyBean.java
package testpckg;
public class MyBean {
private String xKey = "xKey in the house";
private String name = "name in the house";
public String getXKey() { return xKey;}
public String getName() { return name; }
public void setXKey(String xKey) { this.xKey = xKey;}
public void setName(String name) { this.name = name;}
}
b) index.jsp
<jsp:useBean id="test" class="testpckg.MyBean"/>
${test.xKey}
In javax.el.BeanELResolver.java, BeanInfo.getPropertyDescriptors() is
giving the ff:
pds[0].getName(): XKey
pds[1].getName(): class
pds[2].getName(): name
That BeanInfo.getPropertyDescriptors() call is in :
protected final static class BeanProperties {
private final Map<String, BeanProperty> properties;
private final Class<?> type;
public BeanProperties(Class<?> type) throws ELException {
this.type = type;
this.properties = new HashMap<String, BeanProperty>();
try {
BeanInfo info = Introspector.getBeanInfo(this.type);
PropertyDescriptor[] pds = info.getPropertyDescriptors();
for (int i = 0; i < pds.length; i++) {
this.properties.put(pds[i].getName(), new BeanProperty(
type, pds[i]));
}
} catch (IntrospectionException ie) {
throw new ELException(ie);
}
}
It looks like Java is taking XKey from getXKey().
I could make the code convert the first character of the property to
lowercase but I not sure about that.
My settings:
TC6.0.18
Java 1.5
Regards,
Karl
