本文分析了Tomcat启动时报错的具体原因，指出错误是由于尝试加载不匹配平台类型的Apache Tomcat Native库导致，并通过调整server.xml中Context节点的docBase属性指向实际存在的虚拟目录解决了问题。

为什么80%的码农都做不了架构师？>>>

启动tomcat时报错，如下

google了一下，有文章说是因为jdk和tomcat不是都为32位和64位，但是我的tomcat不是第一次运行时就无法启动，之前都可以正常启动。因此，初步怀疑的是配置文件的问题，经实验发现，tomcat conf目录下的server.xml文件配置的context节点的docBase指定的虚拟目录不存在所致。删除该context节点，启动tomcat成功。

<Host name="www.yourcompany.com"  appBase="webapps"  unpackWARs="true" autoDeploy="true">
			<Alias>yourcompany.com</Alias>
            <!--切记：docBase属性指定的虚拟目录一定要物理存在-->
			<Context path="/sw" docBase="sw"/>			  
</Host>
