Tomcat与Intellij的结合IDEA：没有编译器可用

Question

我只是在Arch Linux上测试Intellij IDEA与Tomcat 7服务器结合使用。

我在http://wiki.jetbrains.net/intellij/Creating_a_simple_Web_application_and_deploying_it_to_Tomcat启动Tomcat时

sudo /etc/rc.d/tomcat start 

我只是用教程配置的IntelliJ得到了标准的Tomcat页面。

只是一个空白的项目，但运行Tomcat开放本地主机：在8080的Webbrowser导致异常如下：

我不知道为什么Java编译器丢失。 Java的首页是在Tomcat中的conf正确

/opt/java 

设置任何人可以帮助我吗？

错误是误导性的，它找不到Jasper JSP编译器，而不是Java编译器。

这是org.apache.jasper.compiler.JDTCompiler，它不能从classpath加载，这意味着它（jasper.jar）最可能的JAR文件并没有到达那里的某些原因。

您是从apache下载/解压缩的Tomcat，还是从您的Linux分发仓库安装它？分发包mangle包结构有时...
