[cosmic-users] Incorrect method signature

[Matthew Gillen]

Hi Nicholas,
In your .cdp file you have this:
    <location>ProxyComponent_svnt</location>
    <execParameter>
      <name>entryPoint</name>
      <value>
        <type>
          <kind>tk_string</kind>
        </type>
        <value>
          <string>create_MyProxyComponent_ProxyComponentHome_Servant</string>
        </value>
      </value>
    </execParameter>
  </artifact>

The "create_MyProxyComponent_ProxyComponentHome_Servant" string tells CIAO what
function to look for. It looks like you have the create function named:
 "createProxyComponentHome_Impl"

Those two strings need to match, so either change the .cdp file or rename your
function to match what's in the .cdp file.
