I have followed the instructions here: http://wiki.alfresco.com/wiki/Install_Extension_without_a_Compile_-_PluginI also have the extension-thread-bound-jcr applied as described here http://forge.alfresco.com/frs/shownotes.php?release_id=298For a multi-valued property, property.getValues() results in

I have the same issue for several month. It seems to me like compilation issue: RMI stubs were compiled with different version of JCR API than 1.0. Unfortunately inside jackrabbit-jcr-rmi-1.4.1.jar in pom.xml they not specified version of this API.


 <!– Runtime dependencies –>
    <dependency>
      <groupId>javax.jcr</groupId>
      <artifactId>jcr</artifactId>
    </dependency>
    <dependency>
      <groupId>org.apache.jackrabbit</groupId>
      <artifactId>jackrabbit-api</artifactId>
      <optional>true</optional>

Anyway the only way to find out what is going on in there: decompile RMI stubs and look into the source code that were generated… Another way: compile jackrabbit-jcr-rmi-1.4.1.jar from sources using your Maven 2 with your dependencies: may be it will help…

We're facing the same problem, using Alfresco 3.0 and jackrabbit jcr-rmi 1.4:
RuntimeExceptionjava.lang.ClassCastException: $Proxy175 cannot be cast to [Ljavax.jcr.Value;

Did you find any solution or further information?

Thanks,

This is how far away I've been able to get, but I haven't been able to solve it. Any idea?

It fails in the file "jackrabbit-jcr-rmi-1.4.1.jar",
class "public class ServerProperty"
method "public Value[] getValues()"
line: return SerialValueFactory.makeSerialValueArray(property.getValues());
Error in exactly "property.getValues()"

And the stacktrace is:
