Problem(Abstract) |
Common causes and resolutions for the
java.lang.AbstractMethodError exception. |
|
|
|
Cause |
The java.lang.AbstractMethodError is usually caused by a
misconfiguration or incompatibility of the JDBC™ Driver. |
|
|
Resolving the
problem |
Some common problems that cause the java.lang.AbstractMethodError to occur
when using Oracle JDBC Driver:
- The classes111.zip driver file is used when configuring the JDBC
Provider using the Oracle JDBC Driver.
WebSphere® Application Server v5.0 releases support JDK™ 1.3.1, which
requires the classes12.zip (for JDK 1.2.x and 1.3.x). The classes111.zip
driver file is for JDK 1.1.
- There is more than one occurrence of the classes12.zip file in the
WebSphere Application Server classpath.
Make sure the Enterprise Application (EAR) does not include any JDBC
Driver JAR or ZIP files.
When configuring the JDBC Driver, the JDBC Driver jar files can be located
anywhere on the file system. It is not a requirement to put them in the
Install_Root /lib. If they are copied to install_Root /lib,
make sure that the JAR files from that directory are used in the
configuration.
Click Test Connection on the Administrative Console to perform a
successful test for the data source. The java.lang.AbstractMethodError
occurs only on the execution of any method of the connection object, where
the connection object is successfully obtained; for example,
Connection.executeQuery(). |
