Configuring user role based navigation from error page in Seam framework
Let us assume a scenario where multiple roles exist for users. But we wish to display a single error page and from this error page they should click a button (or link) and go to their respective home page.
This can be achieved by using the following code snippet which is in error.xhtml
<h:form id="errorform">
<h3> <rich:messages errorClass="error" level="warn"/></h3>
<h:commandLink action="/role1/main1.xhtml" rendered="#{s:hasRole('role1')}">
<h3>Click Here To Proceed </h3>
</h:commandLink>
<h:commandLink action="/role2/main2.xhtml" rendered="#{s:hasRole('role2')}">
<h3>Click Here To Proceed </h3>
</h:commandLink>
</h:form>
We will configure the redirection in pages.xml as below.
<exception class= "java.lang.RuntimeException"> <redirect view-id="/error.xhtml"> <message severity="warn">Cannot perform the requested operation due to error. </message> </redirect> </exception>
