试图让我的应用程序连接到 oracle。使用 ojdbc6.jar（使用 Java 6）。Maven 3.0.4。Tomcat 7.0.42（全新安装）。这是我的 context.xml：
<Context reloadable="true" crossContext="false">
<Valve className="org.dcri.tomcat.auth.ExtendedFormAuthenticator" includePassword="false" />
<Realm className="org.dcri.tomcat.auth.DatabaseServerLoginModule"
connectionName="xxxxxx"
connectionPassword="xxxxxx"
connectionURL="jdbc:oracle:oci8:@xxxxxx"
driverName="oracle.jdbc.OracleDriver"
digest="SHA1"
.......
使用 sqlplus，我可以登录到 db 没问题。尝试连接应用程序时，我得到：`
