java - JBPM 仪表板生成器应用程序无法启动

Question

我在 Tomcat 8.0.11 和 JRE 1.8.0_20 中部署了 dashboard-builder-6.1.0.Final.war 应用程序。最初有 ClassNotFoundException 这很好，我找到了所需的依赖项并将它们提供给它。在我的例子中是 slf4j-api-1.7.7.jar 和 cdi-api-1.2.jar。

不幸的是，当尝试通过 http://myhost.com:8080/dashboard-builder/ 打开 JBPM 仪表板时，遇到了更令人困惑的事情。 :

org.apache.jasper.JasperException: An exception occurred processing JSP page /login.jsp at line 162

159: 
160:     <div id="login-content">
161:         <%
162:             LocaleManager localeManager = LocaleManager.lookup();
163:             Locale currentLocale =  localeManager.getCurrentLocale();
164:             SessionInitializer.PreferredLocale preferredLocale =  SessionInitializer.getPreferredLocale(request);
165:             if (preferredLocale != null) currentLocale = preferredLocale.asLocale();


Stacktrace:
    org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:568)
    org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:470)

    javax.servlet.http.HttpServlet.service(HttpServlet.java:725)

我真的看不出这是什么原因。任何想法将不胜感激，谢谢!

您使用的是 tomcat 发行版吗？你关注了吗https://github.com/droolsjbpm/dashboard-builder/blob/master/builder/src/main/tomcat7/README.md ？
