Hi I set the attribute in another matcher that executed prior to this one. It's in a different processor. Does this matter? Yes, I did mean to do things this way but that doesn't mean it makes sense! What I want to be able to do is pass some indication of the result of processing one matcher to a matcher later in the chain. I figured that I could do this by setting attributes in the context. Is there an alternative? The "per recipient" bit is because there can be a variety of reasons why a recipient be matched in the first matcher, and I want to pass that information forward. Advise on best practice most certainly invited.
And I'll look at your coding suggestion as well of course. Thanks Noel Martin -----Original Message----- From: Noel J.

When did you setup those attributes, and do you really mean to have a global attribute in the MailetContext per e-mail address and named by the address? Same question, but did you mean to be calling getInitParameter? --- Noel -----Original Message----- From: Martin Woolley [mailto:[EMAIL PROTECTED]] Sent: Thursday, January 16, 2003 16:03 To: James Users List (E-mail) Subject: ClassCastException / getAttribute Hi I'm playing around with James, getting myself familiar with the way mailets and matchers are written. I ran into a problem today though wherein the code below generated a ClassCastException. Extracts from the mailet.log file and spoolmanager.log file (which includes the exception) follow. The problem appears to emanate from the call to MailContext.getAttribute. Any obvious schoolboy errors in here? Thanks public Collection match(Mail mail) { MailetContext mc = getMailetContext(); Object o [] = mail.getRecipients().toArray(); ArrayList matchedRecipients = new ArrayList(); int l = o.length; for (int i=0;i<l;i++) { MailAddress ma = (MailAddress) o[i]; log("Checking reason attribute for recipient: "+ma.toString()); Object r = mc.getAttribute(ma.toString()); if (r != null) { String reason = (String) r; log("Reason = "+reason); if (reason.indexOf("NaughtyWords") > -1) { log("This recipient needs vetting for naughty words"); matchedRecipients.add(ma); } } } return matchedRecipients; } mailet.log contains: 16/01/03 20:56:30 INFO James.Mailet: FoundNaughtyWords: Checking reason attribute for recipient: rebecca@localhost 16/01/03 20:56:30 INFO James.Mailet: ToRepository: Storing mail Mail1042750587968-1 in file://var/mail/error/ spoolmanager.log contains: 16/01/03 21:02:01 ERROR spoolmanager: Exception in processor <vetting> java.lang.ClassCastException: java.lang.StringBuffer at com.woolleynet.james.matchers.FoundNaughtyWords.match(Unknown Source) at org.apache.james.transport.LinearProcessor.service(LinearProcessor.java:319) at org.apache.james.transport.JamesSpoolManager.process(JamesSpoolManager.java: 385) at org.apache.james.transport.JamesSpoolManager.run(JamesSpoolManager.java:315) at org.apache.avalon.excalibur.thread.impl.ExecutableRunnable.execute(Executabl eRunnable.java:47) at org.apache.avalon.excalibur.thread.impl.WorkerThread.run(WorkerThread.java:8 0) 16/01/03 21:02:01 ERROR spoolmanager: An error occurred processing Mail1042750919465-1 through vetting 16/01/03 21:02:01 ERROR spoolmanager: Result was error -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]> -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]> -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
