Hi Tegala,

Get rid of the following two lines from your portalapp.xml.

<property name="ComponentType" value="jspnative"/>
<property name="JSP" value="pagelet/ShowTable.jsp/"/>

Add a line

<property name="SecurityZone" value="com.wwy.ess/low_safety"/>

Prakash,

Changed as you specified, still getting this error. I did specify the bean scope as Application still gives me this error .

Thanks very much for your help

Add a constructor in your bean and instantiate the model like this.

public TableBean(){

model = new DefaultTableViewModel();

}

There is nothing wrong with your JSP. Have you deined as model public like following in the bean. Post your bean and how you are creating your bean in JSPDynpage.

public DefaultTableViewModel model;

[Former Member]

can you post your JSP.

[Former Member]

Hi,

I think your bean class doesn't have get/set methods for model.

Hope this might help you.

Thanks,

Shiva
