Hi I am facing a similar problem using the graphical tool as explained in the reference manual for JBoss 4.3. The problem I am facing is that the <implicit-mode> tag is not being accepted by the dtd: http://www.jboss.org/portal/dtd/portal-object_2_6.dtd. It is also not accepting the tag. Please advise on how to use the coordination related tags in the dtd. Also I want to know that which object.xml should have these coordination tags: source or target portlet??
