Description
Description:
An Application with a JDBC call procedure activity fails to start with the error "linkagerror." This is related to Oracle JDBC driver classes.
Symptoms:
The following error will be seen in the Studio console log.
java.lang.LinkageError: loader constraint violation in interface itable initialization: when resolving method "com.tibco.bw.jdbc.datasourcefactory.oracle.OracleDataSourceFactory.createDataSource(Ljava/util/Properties;)Ljavax/sql/DataSource;" the class loader (instance of org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) of the current class, com/tibco/bw/jdbc/datasourcefactory/oracle/OracleDataSourceFactory, and the class loader (instance of org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) for interface org/osgi/service/jdbc/DataSourceFactory have different Class objects for the type ory.oracle.OracleDataSourceFactory.createDataSource(Ljava/util/Properties;)Ljavax/sql/DataSource; used in the signature
at java.lang.Class.getDeclaredConstructors0(Native Method)
++++++
Cause:
The driver JARs are not being provisioned correctly with conflicting driver classes from unnecessary JAR files being pushed to the runtime.
Resolution
Review the following locations for the existence of unnecessary JAR files.
- <BW_HOME>\bw\6.x\config\design\thirdparty
- <BW_HOME>\bw\6.x\config\drivers\shells\jdbc.oracle.runtime\runtime\plugins\com.tibco.bw.jdbc.datasourcefactory.oracle\lib
- <BW_HOME>\bw\6.x\system\lib
Ensure that only ojdbc*.jar files are present for the Oracle driver. You will need to reprovision the driver using "bwadmin install oracle-driver" after deleting unwanted files.
