how to call a page on a jsf button click

Question

I'm using JSF, trying a to call a page on a button click inside a data table using the following code

 <h:column> <h:outputText value=""/> <h:commandButton id = "btn" value="History" action="#{Bean.showHistory}"> </h:commandButton> </h:column>

My bean class icludes a method "showHistory" which returns success and I've included the navigation rule in faces-config.xml too but still the page couldn't be called. My navigation rule looks

<managed-bean> <managed-bean-name>Bean</managed-bean-name> <managed-bean-class> com.bean.HistoryBean </managed-bean-class> <managed-bean-scope>request</managed-bean-scope> </managed-bean> <navigation-rule> <display-name>List</display-name> <from-view-id>/BookList.jsp</from-view-id> <navigation-case> <from-outcome>success</from-outcome> <to-view-id>/History.jsp</to-view-id> </navigation-case> </navigation-rule>

Bean Class consists of showHistory() as

public String showHistory() { return "success"; }

Can I get a help to resolve this????

Is your method called at all (Letter "B" should be lowercase, a typo?). How does your navigation rule look like? — Matt Handy

I've included my navigation rule in my post..in the BookList.jsp the button History in placed, when clicked should open History.jsp.U can also find the managed bean, where HistoryBean class consists of method showHistory() which returns success. — Mango

Do you have another action method in your bean that returns "succes"? If so, you should add the <from-action>#{bean.showHistory}</from-action> to your navigation case. — Matt Handy

Ensure you put the command button inside a h:form element: it should work!

From your source code everything looks good (of course including Pier's suggestion to use the h:form tag).

Try to debug and check if your action method is called at all.

If not, then maybe your from-view-id element does not match. As a test you could try it with an empty element (default navigation for all pages):

<from-view-id></from-view-id>

If this works, then the problem is with your from-view-id element. Maybe it's in a different folder or an upper/lower case typo.

thanks for ur time Handy.I tried debugging it couldn't call the method as u said,but acc to Pier's suggestion it worked fine
