--------------------------------------
Summary: Addition of OSGi-aware javax.activation bundle
Key: SLING-2835
URL: https://issues.apache.org/jira/browse/SLING-2835
Project: Sling
Issue Type: Improvement
Components: Extensions
Reporter: Robert Munteanu
Currently Sling exposes the javax.activation package using a system framework
extension. This works well for some use cases. However, it does not work well
with the official javax.mail bundle. The javax.mail bundle is now OSGi-aware,
but the classloading problems between javax.mail and javax.activation persist.
javax.activation tries to read a /META-INF/mailcap file from the javamail jar
and loads DataContentHandler classes from the javamail jar.
To prevent this problem from occuring I have created a javax.activation bundle
which provides a custom CommandMap implementation. This implementation uses the
foreign bundle's classloader ( e.g. javax.mail classloader ) to load classes.
This solves the classloading conflict between javax.mail and javax.activation.
I will attach a zip archive of the maven project to the bundle as a
contribution. The file is named org.apache.sling.javax.activation.zip and has
the sha1sum cd4ad4279b5673a070d919a118d9aca571656f91 , md5sum
68487bdca46ba47bce9947087bd659ea .
