[opencms-dev] How to instantiate a new CmsJspActionElement into a servlet ?

[Xavier Ottolini]

Thanks Andras.

Now this error is no more generated.
I instantiate my CmsJspActionElement object like this :

_jspxFactory = JspFactory.getDefaultFactory();
pageContext = _jspxFactory.getPageContext(this, request, response,null, 
true, 8192, true);
cms = new  CmsJspActionElement(pageContext,request,response);
redirect = cms.link("/www/fr/ecard/cartes.jsp");


The problem is that cms.link returns the following string : "+++ error 
generating link to '/www/fr/ecard/cartes.jsp' +++"
I should tell to the CmsJspActionElement that it is in the opencms VFS. 
How can I do this ?
