You might want to avoid anything to do with reflection altogether. If
you xml is something like this:
<menuitems>
<menuitem>
<name>Button1</name>
<action>Widget1</action>
</menuitem>
<menuitem>
<name>Button2</name>
<action>Widget2</action>
</menuitem>
</menuitem>
Try something like
if ("Widget1".equals(menuItem.getName())) {
horizontalPanel.add(new Widget1());
} else if ("Widget1".equals(menuItem.getName())) {
horizontalPanel.add(new Widget2());
}
Unless you have tons of Widgets this will be manageable. I believe
this method may also help avoid issues with the -XdisableClassMetadata
flag in the upcoming GWT 2.0.
