Subject can't remove jar file from database (ERROR X0X13)!!!
Date Mon, 12 May 2008 15:08:38 GMT
Hello,

how can i see which jars are included in my database? I want to see
all jars which are added through a call of 'CALL sqlj.install_jar
[...]'.

the main problem is:

yesterday i added a jar to my database via the call of:

ij> CALL sqlj.install_jar('/me/netBeansPojects/java/DerbyZeroCheck/dist/DatabaseRoutines.jar',
'APP.Sample1', 0);

Notice: [...]Pojects[...] is a typo but that is ok!!!

You can see the jar in the filesystem:

ls DATACENTER/SM_DATA_LAYER/jar/APP/
SAMPLE1.jar.G1210431624637

today i tried to remove the jar via a call of:

ij> CALL sqlj.remove_jar('APP.Sample1', 0);

The call above always produces this errror:

ERROR X0X13: Jar file 'SAMPLE1' does not exist in schema 'APP'.

here the server side stacktrace:

If i'm trying to include/install an additional jar file everything works fine:

ij> CALL sqlj.install_jar(
    '/me/netBeansPojects/java/DerbyZeroCheck/dist/DatabaseRoutines.jar',
'APP.Sample1', 0);
> Statement executed.

here layout of filesystem before removing:

ls DATACENTER/SM_DATA_LAYER/jar/APP/
SAMPLE1.jar.G1210431624637  SAMPLE1.jar.G1210597561003

ij> CALL sqlj.remove_jar('APP.Sample1', 0);
Statement executed.
ij>

layout just after removing:

ls DATACENTER/SM_DATA_LAYER/jar/APP/
SAMPLE1.jar.G1210431624637

It seems to be impossible to remove the file named
'SAMPLE1.jar.G1210431624637'! It would be nice to know, how to make
included/installed jars visible and how to remove them if a call of
sqlj.remove_jar fails.

Is it save to remove the file manually from filesystem (e.g. rm
SAMPLE1.jar.G1210431624637)?

my environment is:

Linux 2.6.25.1 && java version "1.6.0_06 && derby 10.4


If you need additional infos, please let me know. Any help is appreciated.

TNX in advance!

Sebastian
