我无法获取tomcat7来编译jsps。直到运行示例servlet一切正常,并且服务已启动并正在运行。我正在运行oracle java 8。
谁能指出我正确的方向?
这是堆栈跟踪:

note The full stack trace of the root cause is available in the Apache Tomcat/7.0.35 logs.
该代码看起来像这样,它是来自tomcat7的示例代码,所以我想这是正确的。

<h1>JSP 2.0 Examples - Hello World SimpleTag Handler</h1>
<hr>
<p>This tag handler simply echos "Hello, World!" It's an example of
a very basic SimpleTag handler with no body.</p>

<b><u>Result:</u></b>
<mytag:helloWorld/>
