Servlet to portlet. can see test page but not my servlet

Question

Hello all.
-I'm trying to register a very basic servlet (it just write a message in get or post methods) named mpi_servlet.class
-I followed the instructions of "Packaging and Deploying Your Provider" and made the changes to the files.
-Copy mpi_servlet.class at <war working directory>\WEB-INF\classes.
-Write the following to <war working directory>\WEB-INF\providers\mpi\provider.xml.
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<?providerDefinition version="3.1"?>
<provider class="oracle.portal.provider.v2.DefaultProviderDefinition">
<session>false</session>
<useOldStyleHeaders>false</useOldStyleHeaders>
<portlet class="oracle.portal.provider.v2.DefaultPortletDefinition">
<id>1</id>
<name>MPI</name>
<title>MPI Portlet</title>
<description>MPI Portlet.</description>
<timeout>10000</timeout>
<timeoutMessage>MPI Portlet timed out</timeoutMessage>
<showEdit>false</showEdit>
<showEditDefault>false</showEditDefault>
<showPreview>false</showPreview>
<showDetails>false</showDetails>
<hasHelp>false</hasHelp>
<hasAbout>false</hasAbout>
<acceptContentType>text/html</acceptContentType>
<renderer class="oracle.portal.provider.v2.render.RenderManager">
<contentType>text/html</contentType>
<showPage>/mpi_servlet</showPage>
</renderer>
</portlet>
</provider>
-Write the following to <war working directory>\WEB-INF\deployment\mpi.properties
serviceClass=oracle.webdb.provider.v2.adapter.soapV1.ProviderAdapter
loaderClass=oracle.portal.provider.v2.http.DefaultProviderLoader
showTestPage=true
definition=providers/mpi/provider.xml
autoReload=true
-Zip and rename to mpi.war
-Copy mpi.war to <ear working directory>
-Write the following to <ear working directory>\META-INF\application.xml
<?xml version="1.0"?>
<!DOCTYPE application PUBLIC "-//Sun Microsystems, Inc.//DTD J2EE Application 1.3//EN" "http://java.sun.com/dtd/application_1_3.dtd">
<application>
<display-name>Template Application</display-name>
<description>This is a template application</description>
<module>
<web>
<web-uri>mpi.war</web-uri>
<context-root>/mpi</context-root>
</web>
</module>
</application>
- Zip and rename to mpi.ear
-After deploy it at OEM Console and try "http://myhost:7777/mpi/providers/" I got the test page
Congratulations! You have successfully reached your Provider's Test Page.
Checking for components:
Portlets are:
MPI
Recognizing initialization parameters.

- The problem is that I cannot access my servlet at "http://myhost:7777/mpi/mpi_servlet/"

Hi Marko,
You need to update the web.xml file in WEB-INF folder
Add the following lines to it,
<servlet>
<servlet-name>mpilogin</servlet-name>
<servlet-class>add the fully qualified class file name here</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>mpilogin</servlet-name>
<url-pattern>/mpi_servlet</url-pattern>
</servlet-mapping>
