java - 使用Payara-Micro部署JavaEE应用程序时出现"org.apache.jasper.JasperException: PWC6345"错误

Question

我正在以编程方式在 Payara Micro 上部署 JavaEE 应用程序。它在 Netbeans IDE 中工作正常，但在 cmd 中使用 java -jar myapp.jar 时出现以下错误。

Payara Micro 似乎找不到 javac。关于如何解决这个问题的建议将不胜感激。

• 我将 JAVA_HOME 设置为 C:\Program Files\Java\jdk1.8.0_111
• 我在 Windows 7 上使用 Payara-micro 4.1.1.164。

Answer 1

检查 java 命令是否引用 JDK 而不是 JRE。如果没有，请使用 C:\Program Files\Java\jdk1.8.0_111 中的 java 命令，或设置 C:\Program Files\Java\jdk1.8.0_111 作为 java.home 系统属性，如下所示:

java -Djava.home="C:\Program Files\Java\jdk1.8.0_111" -jar myapp.jar

Payara Micro 尝试在类路径或 java.home 系统属性定义的文件夹中查找 java 编译器来编译 JSP，但找不到它。

详情参见 ToolPovider.getSystemJavaCompiler() 源码，Payara Micro 使用它来查找 Java 编译器。
