When I rebuilded my classes, Tomcat throws error HTTP 500 with "Unable to
instantiate Action, test.Settings,  defined for 'Settings' in namespace
'/'null - action...". Earlier, my app builds without errors... This error is
because I try to staticly instatiate the Account class?
My rebuilded classes:
Account:
************
package test;

public class Account extends BankSupport{                //BankSupport
extends ActionSupport

    public Account()  {
    }
    
    private int currentAmount = 0;
    
    public void setCurrentAmount(int _currentAmount){
        currentAmount = _currentAmount;
    }
    
    public int getCurrentAmount(){
        return currentAmount;
    }
}
****************
Settings class
****************
package test;

public class Settings extends BankSupport{
  Account ac1, ac2, ac3;

          public Settings()  {
        
        ac1.setCurrentAmount(500);
        ac2.setCurrentAmount(300);
        ac3.setCurrentAmount(0);
      
       }
   
    public String execute(){
        return SUCCESS;
    }
}

*******************
My index.jsp is without changes.
My struts.xml:
*******************
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd";>

<struts>

    <constant name="struts.enable.DynamicMethodInvocation" value="false" />
    <constant name="struts.devMode" value="true" />

    <include file="bank.xml"/>

</struts>
****************
and my bank.xml:
****************
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
        "http://struts.apache.org/dtds/struts-2.0.dtd";>

<struts>

    <package name="test" extends="struts-default">

        <action name="Settings" class="test.Settings">
            <result name = "success" >index.jsp</result>
        </action>

    </package>
</struts>
******************
all looks good - so where`s bug?

Regards,
C.
