Problem with scanning Jar files for Converters if application is loaded with
webstart
-------------------------------------------------------------------------------------
Key: CAMEL-522
URL: https://issues.apache.org/activemq/browse/CAMEL-522
Project: Apache Camel
Issue Type: Bug
Components: camel-core
Affects Versions: 1.3.0, 1.4.0
Environment: Windows XP
Reporter: Andreas Kuhtz
Fix For: 1.4.0
Attachments: ResolverUtil.patch
I've encountered a problem with the scanning of jar files with the @Converter
annotation if the Jars are loaded with the webstart classloader. Because the
URL starts with _http:_ the conversion to a file fails in ResolverUtil.
I've attached a patch that uses an UrlResource if the url starts with _http:_
and this works if the jar-resource has the version information added to the jar
file in the JNLP-file (like <jar href="camel-core-1.4-SNAPSHOT.jar"/>). But if
the version is added separately (like <jar href="activemq-core.jar"
version="5.1.0"/>) it fails because the classloader returns the name of the
jar-file without the version information (like http://....../activemq-core.jar)
and this file does not exist.
I'm currently trying if it is possible to check whether the application is
started via webstart (there is a class Tool that should only exist in the
webstart classloader) and in this case I'll check if the filename of the
jar-file is returned correctly. If yes maybe we can provide another patch to
get rid of the problem described above.
