Hello,
maybe the steps you follow are decisive :
- ".jar" files are only .zip files, but zip files have too many internal
formats
- maybe the jar generation defaults are changed from what your derby
"expects"
if you gives the usual details (JDK, jva -version, commands, ...) one
could replicate
the environment and your specific situation.
Bye,
Davide Grandi

If I start from a new database (named docentries), I packed it in a jar, I can
connect with ij and run a select command.
If I run the code from my java classe, I get the error

I connect with db = new DBConnector("jdbc:derby:classpath:docentries");

Also, look inside the jar file for a directory called docentries/seg0.
Does it contain a file called c560.dat?

Sorry. Make that query:
SELECT s.schemaName, t.tableName, c.conglomerateName
FROM sys.sysConglomerates c, sys.sysSchemas s, sys.sysTables t
WHERE c.conglomerateNumber = 1376
AND c.tableID = t.tableID
AND t.schemaID = s.schemaID
;

Hi François,
Do you have any information or theories about how your database
became corrupted? I have never encountered this situation before. A
database in a jar file should be read-only, so the only theory I have
is that the jar file itself was corrupted by some process outside Derby.
Please run the following query in order to find out what table/index
is corrupted:
SELECT s.schemaName, t.tableName, c.conglomerateName
FROM sys.sysConglomerates c, sys.sysSchemas s, sys.sysTables t
WHERE c.conglomerateNumber = 376
AND c.tableID = t.tableID
AND t.schemaID = s.schemaID
;
Thanks,

Hi
I have a one table database embedded in a jar file. I tried to
access it from ij with java -jar %DERBY_HOME%/lib/derbyrun.jar ij -p
ij.properties
ij.properties is
derby.ui.codeset=utf8
ij.connection.doc=jdbc:derby:jar:(U:/docs/OA/articles/zlib/autconv/a
utconv.jar)docentries
I can see that my table (authors) is in the the database with SHOW
TABLES; I can see the columns
ij> DESCRIBE authors;
COLUMN_NAME
|TYPE_NAME|DEC&|NUM&|COLUM&|COLUMN_DEF|CHAR_OCTE&|IS_NULL&
--------------------------------------------------------------------
----------
NAME1 |VARCHAR |NULL|NULL|20 |NULL |40 |NO
NAME2 |VARCHAR |NULL|NULL|20 |NULL |40 |NO
DATA |VARCHAR |NULL|NULL|50 |NULL |100 |YES
AUTHOR_ID |INTEGER |0 |10 |10 |AUTOINCRE&|NULL
|NO
4 rows selected
But I can't run a select statement:
ij> select * from authors;
ERROR XSAI2: Le conglomerat (1,376) demande n'existe pas.
ij> exit;
I have derby 10.8.2.2
Thanks for any help.
François
