Cause
The license .jar files are missing from the classpath of the JDBC provider's configuration.
Resolving The Problem
Edit your JDBC provider and update the classpath to include the license's .jar files:
- db2jcc_license_cu.jar
This is the DB2 Universal JDBC driver license file that allows access to the DB2 Universal database. Use this JAR file or the following one to gain access to the database. This JAR file ships with WebSphere® Application Server in a directory defined by the following environment variable:
- db2jcc_license_cisuz.jar
This is the DB2 Universal JDBC driver license file that allows access to the following databases: - DB2 Universal
- DB2 for iSeries®
- DB2 for z/OS®
- SQLDS
| ${UNIVERSAL_JDBC_DRIVER_PATH} |
The classpath for the provider is set as follows:
| ${DB2UNIVERSAL_JDBC_DRIVER_PATH}/db2jcc.jar ${UNIVERSAL_JDBC_DRIVER_PATH}/db2jcc_license_cu.jar ${DB2UNIVERSAL_JDBC_DRIVER_PATH}/db2jcc_license_cisuz.jar |
The db2jcc_license_cisuz.jar does not ship with WebSphere Application Server and should be located in the same directory as the db2jcc.jar file, so that the DB2UNIVERSAL_JDBC_DRIVER_PATH points to both. The db2jcc_license_cisuz.jar file is included in all DB2 Connect server editions including DB2 Connect Personal Edition. The license is also part the IBM Database Enterprise Developer Edition. If you already have one of these products, then please use the license file from the DB2 Connect Activation CD. If you have a Passport Advantage account, then remember to download the activation key from Passport Advantage for the DB2 Connect edition that you have purchased.
The db2jcc_license_cisuz.jar file is located in the /db2/license directory of the activation CD or activation file downloaded from Passport Advantage.
