      Description

      Hi,

      I created a custom Mailet and created a jar file from it. I copied the custom-mailet.jar into $JAMES_HOME/conf/lib folder as suggested by $JAMES_HOME/bin/setenv.sh. Then I copied $JAMES_HOME/conf/mailetcontainer-template.conf to $JAMES_HOME/conf/mailetcontainer.conf and added the following line below <processor state="transport" enableJmx="true">
      <mailet match="All" class="com.company.CustomMailet"/> which is the full classpath of the Mailet that I added with custom-mailet.jar

      However, when I want to (re-)start James, the server crashes with the following exception:

      Caused by: java.lang.ClassNotFoundException: com.company.CustomMailet
      at java.net.URLClassLoader$1.run(URLClassLoader.java:217)
      at java.security.AccessController.doPrivileged(Native Method)
      at java.net.URLClassLoader.findClass(URLClassLoader.java:205)

      at org.apache.james.container.spring.bean.factory.mailetcontainer.MailetLoaderBeanFactory.getMailet(MailetLoaderBeanFactory.java:45)
      ... 29 more

      To my understanding, James does not find the class that I added with $JAMES_HOME/conf/lib/custom-mailet.jar. Is this a bug or am I doing something wrong?

      Thanks!
