UPDATE:好吧,似乎只有當我嘗試本地調試時,這是一個問題。在Jetty上發佈時(不是同一臺機器),它的效果很好。在本地調試時可以配置Run-Jetty-Run使用的jetty.xml文件嗎?JNDI查找失敗(NameNotFoundException)
我只是浪費了一個下午的時間試圖找到這種情況的原因,但沒有成功...
我設置了一個連接池C3P0我的應用程序。順便說一句,我使用Jetty 7。問題是,當我做了context.lookup得到一個數據源,我得到這個異常:

我有一個jndi.properties文件來配置我的InitialContext(位於我的資源文件夾中的src/main /資源)
java.naming.factory.url.pkgs=org.eclipse.jetty.jndi
java.naming.factory.initial=org.eclipse.jetty.jndi.InitialContextFactory
我也有一個碼頭-env.xml文件在webapp/WEB-INF文件夾:
<Configure class="org.mortbay.jetty.webapp.WebAppContext">
<!--<Set name="ConfigurationClasses">
<Ref id="plusConfig"/>
</Set> -->
<!-- MySql datasource org.eclipse.jetty.plus.jndi.Resource Factory-->
<New id="DSTest" class="org.mortbay.jetty.plus.naming.Resource">
<Arg></Arg>
<Arg>jdbc/DSTest</Arg>
<Arg>
<New class="com.mchange.v2.c3p0.ComboPooledDataSource">
<Set name="driverClassName">com.mysql.jdbc.Driver</Set>
<Set name="url">jdbc:mysql://host/</Set>
<Set name="username">username</Set>
<Set name="password">password</Set>
<Set name="checkoutTimeout">5000</Set>
<Set name="initialPoolSize">10</Set>
<Set name="maxIdleTime">30</Set>
<Set name="maxPoolSize">160</Set>
<Set name="minPoolSize">10</Set>
<Set name="maxStatements">200</Set>
<Set name="maxConnectionAge">0</Set>
<Set name="acquireIncrement">15</Set>
</New>
</Arg>
</New>
</Configure>
而且我在web.xml中添加這些行文件:
<resource-ref>
<description>DB Connection</description>
<res-ref-name>jdbc/DSTest</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
我似乎都遵循所有必需的步驟,但這樣做的查找時,我仍然得到javax.naming.NameNotFoundException ...
任何提示?
謝謝!
編輯: 我忘記了我如何做我的查找。
InitialContext ctx = new InitialContext();
DataSource dataSource = (DataSource)ctx.lookup("java:comp/env/jdbc/DSTest");
也許我很傻,但試試「jdbc/DSTest」作爲JNDI名稱,而不是「env/jdbc/DSTest」。 – DwB
剛剛嘗試過,但沒有運氣:/ – Mathieu
您使用的是Jetty 7還是Jetty 6?它看起來像org.mortbay在Jetty 7中變成了org.eclipse,但是你的Resource defintion類仍然是org.mortbay。這可能是問題嗎? –
