Amos Fong 13 Years Ago I ran into this issue as well and found this same solution. However, you can't pass any parameters so you can't do ascending obc's. Please sign in to reply. Reply as... Cancel Ray Augé Amos Fong 13 Years Ago Ah, but you can my friend!#set ($obcClass = $portal.getClass().forName("com.liferay.portlet.journal.util.comparator.ArticleDisplayDateComparator"))#set ($booleanType = $portal.getClass().forName('java.lang.Boolean'))#set ($obcConstructor = $obcClass.getConstructor($booleanType.getField('TYPE').staticValue))#set ($obc = $obcConstructor.newInstance(true)) Please sign in to reply.

Cancel Ray Augé Ray Augé 13 Years Ago Note, this is complicated by the fact that it's a constructor having primitive args, on top of which you can't directly reference static fields in velocity, so getting the primitive type of a class required more reflection tricks.

jelmer kuperus 13 Years Ago I posted something similar to the forums a while back that was even hackier (due to the difficulty of getting to int.class)http://www.liferay.com/community/forums/-/message_boards/message/5514892these are pretty dirty tricks tho Please sign in to reply. Reply as... Cancel Ian White jelmer kuperus 12 Years Ago Until recently (I just did a svn update of the portal trunk) the velocity hook approach was working well, whereby you simply defined your java interface + impl pair in an applicationContext.xml file. See Ray's test-velotool-hook sample.Alas, with the latest trunk code, your beans are not able to be loaded. Fingers crossed this is just a bug and not a decision to stop supporting velocity hooks.
