Question

启动Tomcat服务器7时，我会通过以下消息得到警告：

警告：无法在JMX中注册：[javax.naming.NamingException：无法加载资源工厂类 [根异常为 java.lang.ClassNotFoundException： org.objectweb.jndi.DataSourceFactory]]

由于这是一个警告，因此我跳过了这一点并继续进行。创建数据库连接后，将出现以下异常。

我是否在Tomcat服务器中使用了错误的jar文件或其他任何问题？

InitialContext ic = new InitialContext();
DataSource da = (DataSource) 
ic.lookup("java:comp/env/jdbc/fhirDB");//error... code snippet.
return da.getConnection();

我的ConText文件所在的地方。

<?xml version="1.0" encoding="UTF-8"?>
<Context reloadable="true">
<!-- path="/CosmicFHIRService" docBase="CosmicFHIRService.war" reloadable="true" crossContext="true" -->

<Resource name="jdbc/fhirDB" auth="Container"
    type="javax.sql.DataSource" username="spider3" password="spider3"
    factory="org.objectweb.jndi.DataSourceFactory"
    driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver"
    url="jdbc:sqlserver://CSLK-DKDB-81-1:1433;DatabaseName=FAROE_SPIDERIII;SelectMethod=cursor;"
    maxActive="8" />
    <Transaction factory="org.objectweb.jotm.UserTransactionFactory" jotm.timeout="60" />
</Context>

Answer 1

类org.objectweb.jndi.DataSourceFactory不在Tomcats的类路径中。您必须将包含它的.jar文件放入Apache Tomcat lib文件夹：$CATALINA_HOME/lib/

编辑：根据您的评论，您根本不打算真正使用此类。是您的context.xml文件引用了不存在的类：

factory="org.objectweb.jndi.DataSourceFactory"

和下一个引用可能会失败：

<Transaction factory="org.objectweb.jotm.UserTransactionFactory".../>。

您可以简单地将其更改为其他实现，并根据需要Apache Tomcat documentation中所述更新其他属性。

部署Tomcat 7服务器时org.objectweb.jndi.DataSourceFactory类未找到异常
