[Resolvido] TilesException ao usar tag s:url do Struts 2

Front-end
#1

Pessoal,

estou realizando a troca do nome do projeto e tudo que referencia ele. Por exemplo, pacotes, arquivos de configuração, referencias e etc.

Após realizar a alteração, passou a dar o seguinte erro no console:

Obs: estou usando Struts 2 e Weblogic.

Alguem sabe me ajudar??

#2

Descobri que o erro está ocorrendo nessa funcition em uma JSP.


	function carregaTreeview()
	{
		var carregaTree = $j('#carregaTree').val();
		<s:url id="url" action="carregaTreeview!montaTreeView.action" />
		ajax('<s:property value="%{url}"/>');
	}

A execução não chega até o método montaTreeView da Action CarregaTreeView.

Resta descobrir como solucionar

#3

resolvi inclíndo a parte destacada em negrito, no arquivo web.xml:

<web-app id=“WebApp_9” version=“2.4”
xmlns=“http://java.sun.com/xml/ns/j2ee”
xmlns:xsi=“http://www.w3.org/2001/XMLSchema-instance”
xmlns:javaee=“http://java.sun.com/xml/ns/javaee”
xmlns:web=“http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd”
xsi:schemaLocation=“http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd” >

Não entendi o erro, mas resolvido.
