database - org.objectweb.jndi.DataSourceFactory 类在 Tomcat 7 服务器部署时找不到异常

Question

当我启动我的 Tomcat 服务器 7 时，通过提及以下消息向我发出警告:

WARNING: Failed to register in JMX: [javax.naming.NamingException: Could not load resource factory class [Root exception is java.lang.ClassNotFoundException: org.objectweb.jndi.DataSourceFactory]]

由于这是一个警告，我将跳过它并继续该过程。创建数据库连接后，出现以下异常。

我是否在 Tomcat 服务器中使用了错误的 jar 文件或任何其他问题？

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

我的上下文文件。

<?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(class)org.objectweb.jndi.DataSourceFactory不在您的 Tomcat 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，您根本无意实际使用此类。是你的context.xml引用不存在的类的文件:

factory="org.objectweb.jndi.DataSourceFactory"

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替代实现，并在必要时更新更多属性，如 Apache Tomcat documentation 中所述。 .
