我们在WAS ND 8.5.5.5和SDK 7.0.8.10上运行MFP 7.0。有时用户在执行各种操作时会遇到“服务器错误。请联系服务器管理员”。重试“解决”问题。
来自SystemOut的一些片段记录了失败的操作，在这种情况下“保存通知”：

由于重试没有改变任何“解决”问题我怀疑是环境而不是配置问题。我检查的第一件事是OOM，我还没有看到。然后我通过GC分析工具运行了appserver的详细GC日志，但这也没有给我任何线索。
这是POST数据的内容：
{"action":"DELETE","message":"","downloadLink":"","multiLanguageMessage":[]}
很抱歉，在捕获POST数据时，从用户的角度看错误看起来是一样的，但检查websphere日志时显示“服务器拒绝操作”错误：
[11/9/15 12:40:36:553 CET] 00000113 ServletWrappe E com.ibm.ws.webcontainer.servlet.ServletWrapper service SRVE0014E: Uncaught service() exception root cause servicesServlet: java.net.ProtocolException: Server rejected operation
at sun.net.www.protocol.http.HttpURLConnection.expect100Continue(HttpURLConnection.java:1059)
at sun.net.www.protocol.http.HttpURLConnection.getOutputStream(HttpURLConnection.java:1118)
在ffdc中显示达到堆栈跟踪的深度限制。我尝试使用`引号粘贴这些，但是当我保存它时，它会一直警告我它似乎包含代码。
不确定“服务器拒绝操作”错误是否与java.lang.StringIndexOutOfBoundsException有关系。导致java.lang.StringIndexOutOfBoundsException的失败请求的POST数据内容是：
{"action":"NOTIFY","message":"Test Dennis 6","downloadLink":"","multiLanguageMessage":[{"locale":"en","language":"English","message":"English message."},{"locale":"nl","language":"Dutch","message":"Dutch message."}]}
答案 0 :(得分：0)
对于不包含冒号的HTTP请求标头，可能会发生异常。 HTTP 1.1标准请求标头始终具有冒号。它可能是由于网络拓扑中的防火墙，负载均衡器，代理以某种方式对标头进行了加扰。
另一种可能性：例外是在Wink库中。 worklightadmin war文件包含自己的Wink版本。可能会发生Wink的内部版本与Web服务器中存在的其他Wink版本冲突，即使在其他Web应用程序中也是如此。因此，使用“parent-last”类加载器策略很重要。
在Websphere控制台中：点击服务器＆gt;服务器类型＆gt; WebSphere Application Server ，并选择用于IBM MobileFirst Platform Foundation的服务器。
接下来，按以下方式选择“父母最后”政策：
请在更改后重新启动网络服务器。
