Tout d'abord, as-tu copié le jar de Struts-Layout sous WEB-INF/lib ?

Sinon, dans le struts-config.xml, tu as défini deux actions de path /treeview :

Code xml :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
<action forward="/pages/Treeview.jsp" path="/treeview"></action>
<action path="/treeview" type=" fr.improve.struts.taglib.layout.treeview.TreeviewAction"  scope="request" validate="false">

La deuxième étant une Action Struts-Layout, donne un autre nom à la première.

Merci d'avance

Apparemment, il y a un problème dans Treeview.jsp.
Peux-tu montrer le code de la jsp ?

**c_nvy** · 30/05/2007, 16h49

Au cas où, peux-tu rajouter dans le struts-config.xml l'Action de path /sort comme indiqué ici ?

Sinon, dans le struts-config.xml, je ne vois pas de forward de name="success" vers la jsp Treeview.jsp dans le mapping de l'Action de path /treeViewAction.

As-tu vu aussi qu'étant donné que tu utilises les Tiles, il faut modifier la balise controller dans le struts-config.xml ?

Code xml :

Sélectionner tout - Visualiser dans une fenêtre à part

<controller processorClass = "fr.improve.struts.taglib.layout.workflow.LayoutRequestProcessor"/>

Je ne sais pas si l'erreur vient de là mais le forward, il faut le mettre dans le corps de la balise action comme ceci :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

<action path="/treeViewAction"
	type="com.cap.tree.action.TreeViewAction">
	<forward name="success" path="/pages/Treeview" />
</action>

et tu as bien un tiles de path /pages/Treeview ?
