Benoit Tellier commented on JAMES-2886: --------------------------------------- https://github.com/linagora/james-project/pull/2701 Added support for extending WebAdmin behaviour (adding routes) We might reconsider the way extensions are loaded, for example through the use of SPI. > Unable to usetransitive dependencies at runtime in Guice extension jars > ----------------------------------------------------------------------- > > Key: JAMES-2886 > URL: https://issues.apache.org/jira/browse/JAMES-2886 > Project: James Server > Issue Type: Bug > Components: guice, Matchers/Mailets (bundled) > Affects Versions: 3.4.0 > Reporter: Benoit Tellier > Priority: Major > > As reported by @AaronRegan , we are unable to resolve transitive dependencies > in extension jars. > # Steps to reproduce > Given a maven module containing a custom mailet, instanciating objects as > part of the *service* method that are NOT part of James classpath: > - 1. Start *any* James guice application > - 2. Drop the JAR of the aforementioned in extension-jars folder > - 3. Configure the mailet within the mailet pipeline > - 4. Process a mail and.... > - 5. Notice runtime failures! The service method does not succeed to > instanciate the object not being part of James classpath. > As off commit 42d7d55d5380d13648533160844d30f765a2c6f1, such a JAR could very > well be the *apache-mailet-crypto* JAR. > This would result in : > {code:java} > java.lang.ClassNotFoundException: > org.bouncycastle.mail.smime.SMIMESignedGenerator > at java.net.URLClassLoader.findClass(URLClassLoader.java:382) > at java.lang.ClassLoader.loadClass(ClassLoader.java:424) > at java.lang.ClassLoader.loadClass(ClassLoader.java:357) > ... 82 common frames omitted > Wrapped by: java.lang.NoClassDefFoundError: > org/bouncycastle/mail/smime/SMIMESignedGenerator > at > org.apache.james.transport.SMIMEKeyHolder.createGenerator(SMIMEKeyHolder.java:208) > at org.apache.james.transport.SMIMEKeyHolder.generate(SMIMEKeyHolder.java:251) > at > org.apache.james.transport.mailets.AbstractSign.service(AbstractSign.java:486) > at > org.apache.james.mailetcontainer.impl.camel.CamelProcessor.process(CamelProcessor.java:81) > at > org.apache.james.mailetcontainer.impl.camel.CamelMailetProcessor$MailetContainerRouteBuilder.handleMailet(CamelMailetProcessor.java:178) > at > org.apache.james.mailetcontainer.impl.camel.CamelMailetProcessor$MailetContainerRouteBuilder.lambda$configure$0(CamelMailetProcessor.java:155) > at > org.apache.camel.processor.DelegateSyncProcessor.process(DelegateSyncProcessor.java:63) > ... 75 common frames omitted > {code} > # What to do from here > - Write a test reproducing that behavior... > - Bundle *apache-mailet-crypto* within supported guice app mailets > - Fix that annoying transitive dependency issue - this is in my opinion a > blocker for Guice adoption. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: server-dev-unsubscr...@james.apache.org For additional commands, e-mail: server-dev-h...@james.apache.org
