setViewType(ViewType.jsp)之后报错 渲染jsp有问题?

环境如下:

java version "9.0.1"

c3p0-0.9.5.1.jar

jackson-core-2.5.3.jar

jetty-server-8.1.8.jar

jfinal-3.2-bin-with-src.jar

json-simple-1.1.jar

mchange-commons-java-0.2.10.jar

mysql-connector-java-5.1.20-bin.jar


刚开始学这个, 在config里设置setViewType(ViewType.jsp)之后,

渲染jsp有问题? 运行报错:

注释掉这句就正常了. 求赐教哇

javac 无法编译你的 jsp 文件，试一下从官网首页下载 jfinal 3.2 all 这个 zip 文件，将里头的 jsp jstl 的 jar 包放到项目中去

代码里没啥不一样啊
@Override
public void configPlugin(Plugins me) {
C3p0Plugin cPlugin = new C3p0Plugin("jdbc:mysql://127.0.0.1:3306/JFinal", "root", "root");
me.add(cPlugin);
ActiveRecordPlugin activeRecordPlugin = new ActiveRecordPlugin(cPlugin);
me.add(activeRecordPlugin);
activeRecordPlugin.addMapping("account", Account.class);
}

搜到一个 https://yq.aliyun.com/wenzhang/show_53976

说是 jetty-server的版本与jetty-webapp的版本不一致，将jetty-webapp,jetty-jsp,jetty-server等修改一致后即可正常启动

可问题是 我该怎么改这些版本?

@tryAtry 改用 tomcat 正常，证明还是 jar 包版本不对，使用 jfinal 官网首页的 jfinal-3.2-all.zip 中的有关 jsp/jstl 以及 jetty-server 的 jar 包，用了六年了，一点事没有

@JFinal 我正是用的咱们官网的那个啊,,不知道是不是环境 不对
jdk-9.0.1
eclipse Version: Oxygen.1a Release (4.7.1a) Build id: 20171005-1200
jar包全是官网上的zip解压出来的

tomcat正常了就在tomcat下学jFinal吧 哈哈
