Spring boot Cannot load driver class: oracle.jdbc.OracleDrive

Question

I have driver class in class-path in my jar:

2015-06-18 12:21:40.290 INFO 9453 --- [ main] .b.l.ClasspathLoggingApplicationListener : Application failed to start with classpath: ..... jar:file:/{projecthome}/rest-test/target/rest-test-0.1.0.jar!/lib/ojdbc6-11.2.0.3.0.jar!/]

I got exception:

Factory method 'dataSource' threw exception; nested exception is java.lang.IllegalStateException: Cannot load driver class: oracle.jdbc.OracleDrive

Answer 1

1. In pom.xml add dependency as told by Santosh.

2. In Eclipse IDE Right click upon your Project and select -- Run As -- Maven build... -- in Goals provide below line and Run. I have just removed mvn and pointed ojdbc6.jar location in my local machine.

install:install-file -Dfile=D:\oracle11gXE\app\oracle\product\11.2.0\server\jdbc\lib\ojdbc6.jar -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0 -Dpackaging=jar

3. Again in Eclipse IDE Right click upon your Project and select -- Maven -- Update Project... -- select Force Update of Snapshots/Releases along with other default options and click OK.

4. ojdbc6-11.2.0.jar should reflect under Maven Dependencies.

Answer 2

step 1:You POM.xml file should be

<dependency>
     <groupId>com.oracle</groupId>
     <artifactId>ojdbc6</artifactId>
     <version>11.2.0</version>
</dependency>

Step 2:Download the ojdbc6 driver from oracle website and keep it in your local machine.

step 3:Run maven below command.Dfile is the location where i kept my jar file downloaded from oracle website

mvn install:install-file -Dfile=C:\Users\santosh\.m2\repository\com\oracle\ojdbc6\11.2.0\ojdbc6.jar -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0 -Dpackaging=jar

After running maven command it should create ojdbc6-11.2.0 in your maven repository.After that your problem should be fixed.

Answer 3

Download ojdbc6.jar from Oracle website or if you install oracle11g in your local system you can find ojdbc in jdbc/lib folder.

Add that ojdbc.jar right click --> build path--> configure build path--> Add external jars--> your local machine ojdbc path -->ok.

It worked in my case.

Answer 4

Make sure that in your IDE you click maven reimport if it is not reimporting automatically (i.e. IntelliJ: right click project, Maven, Reimport), as it will compile fine without being on the classpath, but fail at runtime
