Mailet configuration problem
Hi - I am a new user trying to set up the James server on my system and
have ran into a snag....According to the configuration.html document, it
gives an example of how to set up a mailet with a match statement as
follows -
- <mailet match="UserIs=root & HostIsLocal" class="Forward">
I have tried to enter this statement as is, in the james.conf.xml file
just to test it out, as well as my own versions, such as-
(this is just a test example, I plan to create my own class to handle
these emails soon)
<mailet match="RecipientIs=nwag@darkstar,nwag@localhost &
SubjectIs=NEWSLETTER" class="ToProcessor">
<processor> transport </processor>
<notice> NWAG newsletter intercepted </notice>
</mailet>
When I start up the James server, I get the following sort of
error/stack walkback -
Scanning jars for new Blocks...
Reading configuration
Exception in configuration The entity name must immediately follow the
'&' in th
e entity reference.
org.xml.sax.SAXParseException: The entity name must immediately follow
the '&' i

Trying to remove the space following the '&' (as hinted at by this error
message) merely gives a different error message about the need for a
semicolon... I have tried to correct this in just about every way I can
guess at... I assume that this syntax is an extension to XML because
there is no reference, in my books on XML, to using boolean expressions
(that I could find) in this fashion... It appears that the Xerces XML
parser is getting hung up on the "&' symbol an interpreting it as a
reference? I am working in the Windows environment, and downloaded the
March 15, 2001 version if that helps... Much appreciate any help that
can be offered, and I look forward to using and maybe contributing to
the James project...

Mailet installation problems

First, I added the following code to the james.conf.xml file to declare my
new matcher - NwagNewsLetterMatcher
(I will worry about the real class to handle these emails later....)
<!-- Match NWAG Newsletters and send to web server -->
<mailet
match="NwagNewsLetterMatcher=nwag@marcchamberlin.com,nwag@darkstar,nwag@localhost"
class="ToProcessor">
<processor> transport </processor>
<notice> NWAG newsletter intercepted </notice>
</mailet>
Next, I created my own class in a Default package and exported it as a jar
file. This is my class -
import org.apache.mailet.*;
import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;
class NwagNewsLetterMatcher extends GenericMatcher {
private Set recipients;
}
public void init() throws javax.mail.MessagingException
{
StringTokenizer st = new StringTokenizer(getCondition(), ", \t", false);
recipients = new HashSet();
while (st.hasMoreTokens()) {
recipients.add(new MailAddress(st.nextToken()));
}
}
public java.util.Collection match(org.apache.mailet.Mail mail) throws
javax.mail.MessagingException {
Collection matching = new Vector();
MimeMessage mm = mail.getMessage();
String subject = mm.getSubject();
for (Iterator i = mail.getRecipients().iterator(); i.hasNext();) {
MailAddress rec = (MailAddress) i.next();
if (matchRecipient(rec)
&& (subject != null && subject.equals("NEWSLETTER"))) {
matching.add(rec);
}
}
return matching;
}
public boolean matchRecipient(MailAddress recipient) {
return recipients.contains(recipient);
}
As you can see, I borrowed from the RecipientIs and SubjectIs classes in
order to effect a logical "and" match condition between a set of email
recepients and an email subject. Next, I modified the CLASSPATH as follows -
LOCAL_CLASSPATH=Loader.jar;../lib/AvalonAware.jar;../lib/xerces.jar;../lib/mail_1_2.jar;../lib/activation.jar;../lib/mailet.jar;../lib/myprojects.jar
I was very much surprised that I had to also add the mailet.jar file to the
class path as well, in order to resolve references from my classes to
classes contained within that jar! This makes me suspect that I don't fully
understand the development environment because surely this is working for
other developers... Maybe some additional documentation is needed??? ;-)
Anywise, that has gotten me a bit further, but now I am getting the
following error/walkback... Any ideas????
2001.03.18 05:36:49 720 Channel default opened
Main: Could not load matcher (NwagNewsLetterMatcher);

Am I doing something really wrong? Again many thanks for all your patience
and help in getting me started with this James server.....

Re: Mailet configuration problem
Posted by Marc <ma...@easystreet.com>.
Serge - Sure - When I unzipped the James zip file, there is a doc subdirectory
with a file called configuration.html. Within this file there is a section
titled "The Mailet processor pipeline" with a subsection called "Matches" which
starts out with the following paragraph -
The Match interface defines how match class should work. Their work is to split
a Vector of recipients into two: the
ones matching a specified condition and all others. Condition may or
may not be present. You can make one simple
boolean operation merging two matches into one or you can write your
own class implementing the Match interface.
Currently implemented match:
Following the table of matchers, there are the following examples -
Some examples:
- <mailet match="RecipientIsLocal" class="LocalDelivery">
- <mailet match="UserIs=root & HostIsLocal" class="Forward">
- <mailet match="SenderIs=badBoy@myhost,badGirl@yourhost"
class="Null">
The second example was the one I tried to implement... Incidently, none of
these will work since the parser fails on the < encoding reporting the same
error I was getting from my attempts.....
Guess this means I have to write my own matcher classes eh?

Can you point me to where this example is? Boolean logic is not supported,
so I need to chase down and remove this example.
