问题描述

我一直在尝试获得一个配置为Jetty的c3p0数据库连接池，但我一直收到ClassNotFoundException：

我刚刚接触Jetty，我想最终得到phpMyAdmin和WordPress通过Quercus和JDBC连接运行它。以下是我的WEB-INF目录中的web.xml和jetty-web.xml文件。

I'm new to Jetty and I want to ultimately get phpMyAdmin and WordPress to run on it through Quercus and a JDBC connection. Here are my web.xml and jetty-web.xml files in my WEB-INF directory.

jetty-web.xml：

jetty-web.xml:

<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://jetty.mortbay.org/configure.dtd">
<Configure class="org.mortbay.jetty.webapp.WebAppContext">

        <Arg>jdbc/mysql</Arg>
        <Arg>
            <New class="com.mchange.v2.c3p0.ComboPooledDataSource">
                <Set name="Url">jdbc:mysql://localhost:3306/mysql</Set>
                <Set name="User">user</Set>
                <Set name="Password">pw</Set>
            </New>
        </Arg>
    </New>
</Configure>

web.xml：

我猜我错过了几个罐子或东西。目前我已将以下jar放在我的WEB-INF / lib目录中：

I'm guessing that I'm missing a few jars or something. Currently I have placed the following jars in my WEB-INF/lib directory:


c3p0-0.9.1.2.jar

commons-dbcp-1.4.jar

commons-pool-1.5.4.jar

mysql-connector-java-5.1.12-bin.jar

c3p0-0.9.1.2.jar
commons-dbcp-1.4.jar
commons-pool-1.5.4.jar
mysql-connector-java-5.1.12-bin.jar

我也试图把这些jar放在JETTY-HOME / lib / ext，但没有效果...有人请告诉我什么是错误我的配置。

I have also tried to put these jars in JETTY-HOME/lib/ext, but to no avail... Someone please tell me what is wrong with my configuration. I'm sick of digging through Jetty's crappy documentation.

推荐答案

从Jetty 7开始，Jetty已经成为Eclipse基金会的一个项目。在Jetty 6迁移到Eclipse Jetty 7期间，采用了一种新的包结构（请参阅 Jetty 7 Refactoring page）：

Starting with Jetty 7, Jetty has become a project of Eclipse Foundation. During the migration of Jetty 6 to Eclipse Jetty 7, a new package structure has been adopted (see the Jetty 7 Refactoring page):


  • 来自 org.mortbay.jetty.webapp 现在在 org.eclipse.jetty.webapp

  • 来自 org.mortbay的类。 jetty.plus.naming 现在位于 org.eclipse.jetty.plus.jndi

  • Classes from org.mortbay.jetty.webapp are now in org.eclipse.jetty.webapp
  • Classes from org.mortbay.jetty.plus.naming are now in org.eclipse.jetty.plus.jndi

请尝试使用以下 jetty-web.xml （未测试）：

So try with the following jetty-web.xml (not tested):

<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://jetty.mortbay.org/configure.dtd">
<Configure class="org.eclipse.jetty.webapp.WebAppContext">
    <New id="mysql" class="org.eclipse.jetty.plus.jndi.Resource">
        <Arg>jdbc/mysql</Arg>
        <Arg>
            <New class="com.mchange.v2.c3p0.ComboPooledDataSource">
                <Set name="Url">jdbc:mysql://localhost:3306/mysql</Set>
                <Set name="User">user</Set>
                <Set name="Password">pw</Set>
            </New>
        </Arg>
    </New>
</Configure>

但是如果你不需要从Jetty 7的东西，我的建议是坚持Jetty 6（更稳定，更多的文档，更多的资源在互联网上，不复杂等，换句话说，减少疼痛）。

But if you don't need fancy things from Jetty 7, my suggestion would be to stick with Jetty 6 (more stable, more documentation, more resources on Internet, less complicated, etc, in other words, less pain).
