我已经（据我所知）正确地遵循了 xwiki.org 上的所有说明，并且我也在高低搜索了我的错误的答案，但不幸的是我自己无法解决它们。

我下载了两种不同格式的 XWiki。第一个是.exe安装程序，第二个是建议的.xar包，都用于在 Windows 8 64 位机器上使用。

第一个在“独立”模式下完美运行，但是一旦hibernate.cfg.xml文件更改为预设的 MySQL 设置（对我的数据库来说是准确的），我会收到一个很长的HTTP 500错误。（这是在我添加 MySQL Connection Java 文件并根据 xwiki.org 上的说明创建 MySQL 数据库之后）似乎主要问题是它找不到com.mysql.jdbc.Driver以及我稍后收到错误的事实页面说它无法创建数据库连接池。

与错误有关的代码是这样的：

<!-- DBCP Connection Pooling configuration
-->
<property name="dbcp.defaultAutoCommit">false</property>
<property name="dbcp.maxActive">50</property>
<property name="dbcp.maxIdle">5</property>
<property name="dbcp.maxWait">30000</property>
<property name="dbcp.whenExhaustedAction">1</property>
<property name="dbcp.ps.whenExhaustedAction">1</property>
<property name="dbcp.ps.maxWait">120000</property>
<property name="dbcp.ps.maxIdle">20</property>
<property name="connection.provider_class">com.xpn.xwiki.store.DBCPConnectionProvider</property>

和这个

<!-- MySQL configuration.

-->
<property name="connection.url">jdbc:mysql://localhost/xwiki</property>
<property name="connection.username">xwiki</property>
<property name="connection.password">xwiki</property>
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>
<property name="dbcp.ps.maxActive">20</property>
<mapping resource="xwiki.hbm.xml"/>
<mapping resource="feeds.hbm.xml"/>
<mapping resource="activitystream.hbm.xml"/>
<mapping resource="instance.hbm.xml"/>

错误本身如下所示：

我必须使用.xar安装版本才能正确连接到数据库吗？我也尝试过这种方式，使用 Xampp 和 Tomcat。Tomcat 安装良好，我可以通过localhost:(port). 但是，当我尝试访问我的 xwiki 时，我收到一条HTTP 404错误消息，提示找不到引用，这很奇怪，因为它显示在 Tomcat 中包含的部署列表中的其他文件以及那里显示的 Tomcat 示例文件（位于在同一个目录中）工作正常......

我有点担心，即使我可以通过 Tomcat 让 XWiki 正常工作，我仍然会遇到我稍后在尝试连接 MySQL 数据库时提到的第一个错误。

旁注：我怀疑在 XWiki 中发现的文件与在 Tomcat 中发现的文件之间可能存在 Java 文件冲突，这是我在玩弄并试图使事情正常工作时看到的其他错误......但我可能错了，因为我目前有对Java知之甚少。我已经看到了几个 servlet 错误并且找不到类/文件错误，根据我发现的论坛，这些错误是属于jasper.jar和 的常见错误jsp-api.jar，两者都在 Tomcat 中找到。

无论如何，我愿意尝试涉及或不涉及 Tomcat 的安装选项。如果有人成功地在 Windows 上使用 MySQL 数据库安装 XWiki，我们将不胜感激！

看起来您缺少 mysql 驱动程序。由于您将默认发行版转换为使用 mysql，因此您需要下载mysql 驱动程序 jar并将其部署到您的 'webapps\xwiki\WEB-INF\lib' 目录。

关于第二个问题，数据库驱动程序错误、xar 和 tomcat 404 之间可能没有任何联系。xar 只是用于导入或导出内容和功能的页面集合，但通常不处理低级别的东西，例如数据库连接。Tomcat 中的 404 可能是由于您访问了无效的 url。可能需要关于那个的更多细节。

首先关于与 Tomcat 的潜在冲突，我可以向您保证这是不可能的，因为 XWiki 团队一直在生产中使用 Tomcat。

现在对于 MySQL，错误很明显，如果你真的把 MySQL 连接器放在了正确的位置。你放的是哪个版本的#xwiki folder#/WEB-INF/lib/？

XAR 包与安装 XWiki 的方式不同，它是一个包含 wiki 页面的包，可以在 XWiki 运行时导入。也许你的意思是 WAR 包？

这在几个月前得到了解决。我在设置中遗漏了一些重要信息，但现在可以正常工作了。
