schemaCheckEnabled in DbFileSystem
Hi,
I have a NullPointerException when I try to start Jackrabbit with a
DbFileSystem using MySql as RDBMS :
03-mai-2011 13:36:04 org.apache.jackrabbit.core.fs.db.DatabaseFileSystem
init
SEVERE: failed to initialize file system
java.lang.NullPointerException
at java.io.Reader.<init>(Reader.java:61)
at java.io.InputStreamReader.<init>(InputStreamReader.java:55)
at
org.apache.jackrabbit.core.util.db.CheckSchemaOperation.run(CheckSchemaOperation.java:80)
at
org.apache.jackrabbit.core.fs.db.DatabaseFileSystem.init(DatabaseFileSystem.java:197)
at
org.apache.jackrabbit.core.config.RepositoryConfigurationParser$6.getFileSystem(RepositoryConfigurationParser.java:1057)
at
org.apache.jackrabbit.core.config.RepositoryConfig.getFileSystem(RepositoryConfig.java:911)
at org.apache.jackrabbit.core.RepositoryImpl.<init>(RepositoryImpl.java:285)
at org.apache.jackrabbit.core.RepositoryImpl.create(RepositoryImpl.java:605)
When searching a bit, indeed, the "ddl" field of the
CheckSchemaOperation class is null.
When searching further I've noticed that
// check if schema objects exist and create them if necessary
if (isSchemaCheckEnabled()) {
createCheckSchemaOperation().run();
}
in the init() method of the DatabaseFileSystem class.
schemaCheckEnabled is true by default.
I've tried to turn it off but failed.
So, two questions in one here : should I let it turned on ? If yes, how
can I get rid of this npe ? If no, how can I turn it off properly ?
Thanks.
Regards.

Hi Stephen,
No, I've tried to do it in the repository.xml, like what's described
here :
http://jackrabbit.510166.n4.nabble.com/NPE-in-ObservationManagerImpl-with-Jackrabbit-2-1-1-on-JBoss-td2549067.html
I've retried and it works now, thanks a lot.
BUT what if I actually want the table to be automatically created in my
database ? The ddlstream is still null so I get this NPE.
Can it be that this is a access problem to my database ? (I should have
pointed to the mailing-list that I have absolutely no problem with a
full-memory DbFileSystem and PersistenceManager)
Regards.

Did you make sure to turn it off in the workspace.xml for the workspace,
not in the repository.xml?

that's most likely caused by misconfiguration.
make sure you're specifying "mysql" as schema, i.e.
<FileSystem class="org.apache.jackrabbit.core.fs.db.DbFileSystem">
[...]
<param name="schema" value="mysql"/>
[...]
</FileSystem>
