SRVE0207E错误发生在Bluemix上的web服务中。

Question

这是我的web服务在bluemix上的运行时日志。当我试图调用一个API时，它会返回以下错误：

页面上的"Error 500: javax.servlet.ServletException: SRVE0207E: Uncaught初始化异常由servlet创建“，这是显示的日志。

该代码在其他web服务上运行良好。但是当我试图将它合并到这个web服务中时，它就不起作用了。有人能告诉我哪一部分不对吗？

Answer 1

造成此错误的原因是日志中看到的NoSuchMethodError：

myapp: java.lang.NoSuchMethodError: java.lang.NoSuchMethodError

此方法不存在于JAX-RS1.1中，自由服务器正在加载该方法：

9/9/2015 12:15:01 AM OUT App审计CWWKF0012I:服务器安装了以下功能: json-1.0、jpa-2.0、icap:managementConnector-1.0、beanVal环流-1.0、jdbc-4.0、managedBeans-1.0、CloudAutoling-1.0、jsf-2.0、jsp-2.2、servlet-3.0、jaxrs-1.1、jndi-1.0、appState-1.0、ejbLite-3.1、cdi-1.0。

要解决这个问题，您需要停止使用该方法，或者将打包的自由服务器配置推送到包含应用程序和server.xml的Bluemix中，以加载jaxrs-2.0功能而不是jaxrs-1.1功能。有关如何推送打包的自由服务器的详细信息是这里。
