commons-mail with apache felix
Hi,
I am trying to use commons-email-1.2 with apache Felix.
I have started the bundle mail-1.4.jar (including javamail) because
commons-email uses this library. Then I am starting commons-email and there
are no errors.
A third bundle is accessing the SimpleEmail class of commons-email and sends
a mail.
I get following error:
org.apache.commons.mail.EmailException: Unable to locate provider for
protocol: pop3
at org.apache.commons.mail.Email.buildMimeMessage(Email.java:1111)
at org.apache.commons.mail.Email.send(Email.java:1162)

at org.apache.commons.mail.Email.buildMimeMessage(Email.java:1105)
I guess that some properties cannot be loaded because of the classloading in
OSGi but how can I change that?
The source code is:
smtpHost = MailSettings.smtpHost; userName =
MailSettings.smtpUsername; pw = MailSettings.smtpPassword;
emailAddress = MailSettings.fromAddress; pop3Host =
MailSettings.pop3Host; toAddress = emailAddress;
try { SimpleEmail email=new SimpleEmail();
email.setHostName(smtpHost); email.setAuthentication(userName,
pw); email.setFrom(emailAddress, user);
email.addTo(toAddress);
email.setPopBeforeSmtp(true, pop3Host, userName, pw);
email.setSubject(subject); email.setMsg(message);
email.send(); } catch (EmailException e) {
e.printStackTrace(); return false; }
Thx,
Alex

Have a look at servicemix bundles:
http://repo2.maven.org/maven2/org/apache/servicemix/bundles/org.apache.servicemix.bundles.javax.mail/1.4.1_2/org.apache.servicemix.bundles.javax.mail-1.4.1_2.jar
It has been modified to work in OSGi.

I forgot to say that I am working with reflection for getting the class that
implements the send method in the third bundle.
I tried it now without reflection and it works.
Has anyone experience with the side effects of using reflection in the OSGi
environment? Maybe it is a bad idea to use it at all. What I want to achieve
is a dynamic environment in which users can add bundles with certain
functionality (methods). These methods can be combined with an orchestration
language. And for calling a single method I am using reflection as I am only
aware of method names and the belonging classes.
Thx
Alex
