Subject [jira] Updated: (GERONIMO-1001) Derby NetworkServer does not use TCCL
Date Sat, 10 Dec 2005 23:45:08 GMT
     [ http://issues.apache.org/jira/browse/GERONIMO-1001?page=all ]

Aaron Mulder updated GERONIMO-1001:
-----------------------------------

    Fix Version: 1.1

> Derby NetworkServer does not use TCCL
> -------------------------------------
>
>          Key: GERONIMO-1001
>          URL: http://issues.apache.org/jira/browse/GERONIMO-1001
>      Project: Geronimo
>         Type: Bug
>   Components: databases
>     Versions: 1.0-M5
>  Environment: Derby 10.1
>     Reporter: Jeremy Boynes
>      Fix For: 1.1

>
> When calling stored procedures, the Derby engine locates the implementation using three
sources:
> * the Thread's context classloader (TCCL)
> * the database class path (jars that have been loaded in)
> * the classpath of the engine classes themselves
> When embedded in Geronimo as a RAR, we initialize the TCCL to that of the RAR which allows
procedure code to be located in the RAR itself.
> However, if the RAR defines a NetworkServer the TCCL is not inherited by the worker threads
it spawns to service requests from clients and as a result calls to procedures whose implementation
is located in the war will fail with a ClassNotFoundException
