Hello,
I have run into a little problem while ..templating...
The idea was to do an iteration over 2 collections in sync as follows:
#macro (makeList $headings $data)
#set ($it = $data.iterator())
#foreach($heading in $headings)
$heading $it.next()<br/>
#end
#end
Because of the way the reflection is performed we can get
IllegalAccessException because we are working on a private class rather than
one of its interface or possibly public superclass. In the case above we are
working on java.util.AbstractList$Itr, while we would need to work on
java.util.Iterator
The ugly hack I did was the following:
It somewhat prevents huge security problem but not completely I guess.
int modifiers = method.getModifiers();
if ( Modifier.isPublic(modifiers) && !method.isAccessible() ){
method.setAccessible(true);
}
It would probably be better to save the type of the object from a method
return type each time a method call is performed and work on this one.
I modified as well a line so that we have the full exception, it somewhat
bothered me when I ran into this problem since the stacktrace was swallowed
and I only got the message on System.out. This is not a good way to do
anyway since it would be nicer to log into the log rather than system out...
