Deploy a custom mailet in James 3.0.0-beta5

[Benoit Tellier]

Hi,

I am trying to deploy a custom mailet and a custom matcher on my running
James server.

When adding my mailet or my matcher in the mailetcontainer.xml file, I
have a strange error ( repeted thousand of times ). I added the
stacktrace as an attachement for readability.

Here is how my code looks like :

    package com.linagora.openpaas.mailet;

    public class PostMailOnESN extends GenericMailet {

        public void init() throws MessagingException {
            // ...
        }

        public void service(Mail mail) throws MessagingException {
            // ...
        }

        public void destroy() {
            // ...
        }
    }

I added the generated jar in conf/lib directory.

Here is the section of mailetcontainer.xml file involving this mailet :

    <mailet
match="com.linagora.openpaas.matcher.ESNPostmasterMailMatcher=http://127.0.0.1:8080/api/messages/email/check%esn.james.minet.net";
class="com.linagora.openpaas.mailet.PostMailOnESN">
        <esnip>127.0.0.1</esnip>
        <port>8080</port>
        <api>api/james/mail</api>
    </mailet>

Note that it works fine if I replace this mailet by :

        <mailet match="All" class="Null"/>

And That I get the same kind of stacktraces using the following non
existing mailet and matcher :

        <mailet match="Al" class="Null"/>

Or :

        <mailet match="All" class="Nul"/>

Oh and I am running james 3.0.0-beta5, on openjdk-7-jre ( I have the
same problem using openjdk-6-jre )

My question is :
  - have I made something wrong ? ( I have the impression
  - have someone deployed a custom mailet successfully on James
3.0.0-beta5 ? Does you have any tips ?

Thank you by advance,

Benoit
