Subject [jira] [Created] (AMQ-6780) New Postgres JDBC-Driver not recognized
Date Tue, 01 Aug 2017 10:41:00 GMT
Ch.Krauss created AMQ-6780:
------------------------------

             Summary: New Postgres JDBC-Driver not recognized
                 Key: AMQ-6780
                 URL: https://issues.apache.org/jira/browse/AMQ-6780
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 5.15.0
            Reporter: Ch.Krauss


After our switch of the postgres-jdbc-driver from version 9.4-1201 to 42.1.3 the JDBCPersistenceAdapter
does not recognize postgres any more. 
The log:

{code:title=new driver}
2017-07-31 19:35:52,733 [INFO ] 259-949-060 [JDBCPersistenceAdapter : loadAdapter] - Database
adapter driver override not found for : [postgresql_jdbc_driver].  Will use default implementation.
2017-07-31 19:35:52,765 [WARN ] 259-949-060 [DefaultJDBCAdapter : executeStatement] - Could
not create JDBC tables; they could already exist. Failure was: CREATE TABLE ACTIVEMQ_MSGS(ID
BIGINT NOT NULL, CONTAINER VARCHAR(250) NOT NULL, MSGID_PROD VARCHAR(250), MSGID_SEQ BIGINT,
EXPIRATION BIGINT, MSG BLOB, PRIMARY KEY ( ID ) ) Message: ERROR: type "blob" does not exist
  Position: 147 SQLState: 42704 Vendor code: 0
{code}

{code:title=old driver}
2017-07-31 19:37:21,021 [INFO ] 11b-e48-c83 [JDBCPersistenceAdapter : loadAdapter] - Database
adapter driver override recognized for : [postgresql_native_driver] - adapter: class org.apache.activemq.store.jdbc.adapter.PostgresqlJDBCAdapter
{code}

The cause is the change of the name from "postgres_native_driver" to "postgres_jdbc_driver".
The PostgresqlJDBCAdapter uses the name to find the class. 
Our workaround is to add a file "postgres_jdbc_driver" to "META-INF/services/org/apache/activemq/store/jdbc"
in the "activemq-jdbc-store-5.15.0.jar".
