I am trying to use iBATIS in jDeveloper 9 and Tomcat 5.0.28.
I keep getting error: java.lang.NoClassDefFoundError,
under \WEB-INF\lib\
there are : ibatis-2.3.0.677.jar,
log4j-1.2.14.jar;
commons-logging-1.1.jar... and other struts jar.
I searched the online, I guess the problem is in my static init section. I
copied that from online sample code.
see below is error log and BaseIbatisDAO:

Here is my BaseIbatisDAO :
public class BaseIbatisDAO {
private static BaseIbatisDAO instance = new BaseIbatisDAO();
private static Logger log =
Logger.getLogger(BaseIbatisDAO.class.getName());
protected static SqlMapClient sqlMap;
static
{
try
{
log.debug("Attempting to initialize SqlMap");
Reader reader =
Resources.getResourceAsReader("aaa/bbb/ccc/SqlMapConfig.xml");
sqlMap = SqlMapClientBuilder.buildSqlMapClient(reader);
reader.close();
} catch (IOException e) {
// Fail fast.
throw new RuntimeException("Something bad happened while building
the SqlMapClient instance." + e, e);
}
}
-------------------------------------
SqlMapConfig.xml:
<sqlMapConfig>
<!-- Configure a built-in transaction manager. If you're using an
app server, you probably want to use its transaction manager
and a managed datasource -->
<transactionManager type="JDBC" commitRequired="false">
<!--DataSource provided by the container -->
<dataSource type="JNDI">
<property name="DataSource"
value="java:comp/env/jdbc/DisclosureCoreDS" />
</dataSource>
</sqlMapConfig>

Thanks :-)
