Hello,
I am trying to generate Hibernate doc from annotated classes but I get
an exception (see end of message). What can I do?
Is it a problem: in my pom.xml? in Maven Hibernate plugin? in Hibernate Tools?
Maven configuration:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>hibernate3-maven-plugin</artifactId>
<version>2.1</version>
<configuration>
<components>
<component>
<name>hbm2doc</name>
<implementation>annotationconfiguration</implementation>
<outputDirectory>target/hibernate3/hbm2doc</outputDirectory>
</component>
</components>
<componentProperties>
<configurationfile>hibernateConfig.xml</configurationfile>
<jdk5>true</jdk5>
</componentProperties>
</configuration>
<dependencies>
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc14</artifactId>
<version>10.2.0.3.0</version>
</dependency>
</dependencies>
</plugin>
