---------------------------------------
Key: JBAS-1288
URL: http://jira.jboss.com/jira/browse/JBAS-1288
Project: JBoss Application Server
Type: Feature Request
Components: JMX
Versions: JBossAS-4.0.1 Final
Reporter: Michael Kopp
Assigned to: Scott M Stark
Whenever you try to get a PropertyEditor for something but none is there, do
the following additional check:
if (type.getSuperclass().getName().equals("java.lang.Enum"))
{
editor = new EnumPropertyEditor(type);
}
where the EnumPropertyEditor is:
public class EnumPropertyEditor extends PropertyEditorSupport implements
PropertyEditor
{
private final Class targetType;
public EnumPropertyEditor(Class targetType)
{
this.targetType = targetType;
}
public void setAsText(String text) throws IllegalArgumentException
{
try
{
setValue(targetType.getMethod("valueOf",new
Class[]{String.class}).invoke(null,new Object[]{text});
} catch (IllegalAccessException e)
{
throw new IllegalStateException(e);
} catch (InvocationTargetException e)
{
if (e.getTargetException() instanceof RuntimeException);
throw (RuntimeException)e.getTargetException();
throw new IllegalStateException(e);
} catch (NoSuchMethodException e)
{
String err = type.getName() +
" does not contain the required method: public static " +
type.getName() + " valueOf(String);";
throw new IllegalArgumentException(err,e);
}
}
public String getAsText()
{
try
{
return targetType.getMethod("name",null).invoke(getValue(),null)
} catch (IllegalAccessException e)
{
throw new IllegalStateException(e);
} catch (InvocationTargetException e)
{
if (e.getTargetException() instanceof RuntimeException);
throw (RuntimeException)e.getTargetException();
throw new IllegalStateException(e);
} catch (NoSuchMethodException e)
{
String err = type.getName() +
" does not contain the required method: public String name()";
throw new IllegalStateException(err,e);
}
}
}
