How can I set a JSF page to accept requests from outside

Question

I have a file upload page in my application(JSF and MyFaces). It works fine when I navigate to page and select the file to upload and submit. Do I need to make any changes to this page to post from an external system?
I created a perl script to send a file to this page. When I called the URL for this page, it returned the page content. How can I submit from the perl script?
<h:form id="apppostform" name="apppostform" enctype="multipart/form-data" >
          <h:panelGrid styleClass="mbformdata" columns="2" border="0" cellspacing="25" cellpadding="0">
          <h:outputText value="#{appmsg.prompt_upload_file}"/>
          <t:inputFileUpload id="fileupload"
          value="#{fileUploadForm.upFile}"
          storage="file"
          styleClass="fileUploadInput"
          />
               <h:commandButton type="submit" value="submit" action="#{fileUploadForm.uploadFile}"/>
               </h:panelGrid>
</h:form>

I created uploadservlet. I specified in web.xml:
<servlet>
<servlet-name>uploadservlet</servlet-name>
<display-name>UploadServlet</display-name>
<servlet-class>servlet.UploadServlet</servlet-class>
</servlet>
When I try to access uploadservlet, I am getting 404 error.
I have few questions:
How does it know about uploadservlet if it is not inherited from facesservlet while using JSF?
Do I need to add any info about this in faces-config.xml?
Please help!
Thanks
