Calling Java from JSP in a form action

Hi experts,

I have an portal application with:

- portalapp.xml

- ChangePassw.java

- change.jsp

How can call to doContent or doPost from jsp.

My passwd.java:

public class ChangePassw extends AbstractPortalComponent

{

    @SuppressWarnings("null")

  public void doContent(IPortalComponentRequest request, IPortalComponentResponse response)

    {

...

...

}

My change.jsp:

...

<FORM name="helpForm" method="post" action="login.ChangePassw">

...

My portalapp.xml:

...

    <component name="ChangePassw">

      <component-config>

        <property name="ClassName" value="login.ChangePassw"/>

        <property name="SafetyLevel" value="no_safety"/>

        <property name="LocalModeAllowed" value="true"/>

        <property name="ComponentType" value="servlet"/>

      </component-config>

...

What are wrong? The error is:

com.sap.portal.prt.broker.PortalModuleNotFoundException: Could not retrieve portal application login

Thanks in advance,

Regards,
