我多次尝试在我的 Web 应用程序和 Derby 之间建立连接,但我在 Eclipse 控制台中收到了这些错误消息:
INFO: Server startup in 3772 ms
ERROR: Cannot load JDBC driver class 'org.apache.derby.jdbc.ClientDriver'
ERROR: Cannot load JDBC driver class 'org.apache.derby.jdbc.ClientDriver'
11/02/2011 19:08:53 org.apache.catalina.core.StandardContext reload
My class and database definition is showed bellow:
// Obtain our environment naming context
javax.naming.Context initCtx = new InitialContext();
javax.naming.Context envCtx = (Context) initCtx.lookup("java:comp/env");
// Look up our data source by the name we gave it when we created it.
// In this case that's "jdbc/customer".
javax.sql.DataSource ds = (DataSource) envCtx.lookup("jdbc/customer");
conn = ds.getConnection();
And my web.xml and context are showed bellow.
in context.xml ...
Resource name="jdbc/customer"
auth="Container"
type="javax.sql.DataSource"
username="qwert"
password="asdf"
driverClassName="org.apache.derby.jdbc.ClientDriver"
url="jdbc:derby://localhost:1527/C:\\testes_db\\customer;create=true;"
maxActive="8"
and in the web.xml ...
res-ref-name jdbc/customer
res-type javax.sql.DataSource
res-auth Container
-- my second attempt
resource-env-ref-name jdbc/customer
resource-env-ref-type javax.sql.DataSource
我在 Windows 中使用带有 eclipse wtp (europa) 的 tomcat 6。而且我已经将 derby.jar 和 derbclinet.jar 放在了 WEB_INF\lib 目录中......
我可以做些什么来解决这个问题?
谢谢!
