jboss-4.0.0DR3: could not load class: JDBCKeyGeneratorCreate

dirlewanger_klaus May 7, 2004 9:50 AM

Hello together,

i´m just trying to migrate to JBoss version 4 (jboss-4.0.0DR3). I installed it, started ist, set up an initial server configuration, started it again, all works fine.

But now I deployed an EAR-File that works fine on JBoss version 3 (jboss-3.2.0RC3_tomcat-4.1.18), started it and the server has some problems:

I found out that there is looked for

org.jboss.ejb.plugins.cmp.jdbc.JDBCKeyGeneratorCreateCommand



the only existing in jboss.jar
is

org.jboss.ejb.plugins.cmp.jdbc.keygen.JDBCKeyGeneratorCreateCommand



Has anybody an idea? Or is it a bug?

Do any of your deployment descriptors refer to the missing class?

Could be that your application has a bug?

That´s correct! With the migration of

jbosscmp-jdbc.xml

the problem is solved:

<entity-command name="OSV-KEY-GEN" class="org.jboss.ejb.plugins.cmp.jdbc.keygen.JDBCKeyGeneratorCreateCommand"> <attribute name="key-generator-factory"> UUIDKeyGeneratorFactory </attribute> </entity-command>

Do not forget the
.keygen
in the package name.

Thank´s a lot.
Klaus

P.S.:

Should begin a list of topics where JBoss V3.x and V4.x are not up upward resp. downward compatibel. This is the first entry.

Not sure if anything has been added yet but it might be worth adding a 3.x to 4.x FAQ migration page to the Wiki to show the common problems that people encounter.
