class cast exception

[Rafael Fagundes]

Hello!

Well, in a jsp system I'm getting java.lang.ClassCastException: java.lang.String error when trying to access a page. It�s strange because when i visit this page for the first time nothing happens. But if i navigate for while and redirect to "the page", this error occurs.

A time this error appeared when i created a session variable two times, with different names....

PS:
Browser feedback:

java.lang.ClassCastException: java.lang.String
at org.apache.jsp.ConsultaSolicitacoes_jsp._jspService(ConsultaSolicitacoes_jsp.java:74)

Servlet:

ns = (YYY.NucleoSolucionador) _jspx_page_context.getAttribute("ns", PageContext.SESSION_SCOPE);

Thank�s for your attention,
Rafael.

Sorry for my bad english....

Well, something, somewhere in your web app is calling

pageContext.setAttribute("ns", "a string.");

directly or indirectly. Figure out where.
