Actually, there is a JSR168-compliant way to do this, with the help of javascript at portlet ABC , I include a hidden form similar to this <form id="portletABCForm" action="<portlet:actionURL/>" method="post" style="display:none"> | </form> Note that the form id is porletABCForm to indicate that it belongs to portlet ABC, I also create a javascript function function invokeActionURLPortlet(portletName) { | var frm = document.getElementById("portlet" + portletName + "Form"); | if (frm) { | var frmHtml = frm.innerHTML; | for (var i = 1; i < arguments.length - 1; i+=2) { | var parameterName = arguments; | var parameterValue = arguments[i + 1]; | frmHtml += "<input type=\"hidden\" name=\"" + parameterName + "\" value=\"" + parameterValue + "\"/>"; | } | frm.innerHTML = frmHtml; | frm.submit(); | } | } Now, I can invoke the actionURL of portlet ABC by using the above function | <a href="javascript:invokeActionURLPortlet("ABC", "param1" , "value1", "param2", "value2")">Click here to invoke portlet ABC action URL with param1=value1&param2=value2</a> The solution is also posted my blog at http://vpensieve.blogspot.com/ View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3982864#...
