我在使用WebSphere上的JSF 1.1（MyFaces 1.1.8）时遇到问题。在Tomcat 5.5上部署我的应用程序时，此行为不适用，并且一切正常。ExternalContext的Request对象上的getQueryString在WebSphere上返回null
当我尝试从Ogone（支付网关）回发一个网址读取参数，再加入我的JSF会话（会话仍然存在），查询字符串是无法通过
final HttpServletRequest request = (HttpServletRequest)FacesContext
.getCurrentInstance().getExternalContext().getRequest();
String qs = request.getQueryString(); // null on WebSphere, filled on Tomcat
要成为一个位更完整，查询字符串看起来是这样的：
http://100.100.100.100:9080/my_app_context/pages/screen7.jsf?orderID=4208013442596271¤cy=EUR&amount=60&PM=iDEAL&ACCEPTANCE=0000000000&STATUS=9&CARDNO=11-XXXX-11&ED=&CN=K%C3%A9m+Birdy&TRXDATE=08%2F06%2F12&PAYID=15879916&NCERROR=0&BRAND=iDEAL&COMPLUS=personID%3D01%26subscriptionID%3D02&IP=100.100.100.100&SHASIGN=9642468EE016BD49787B62EA7231124B3C24F9BBFC5B3B3B4D9E97D678979E57E5EED9B47D611441A6FCA2EB1D2DB87348C8111ACFF366A4E244106CCCFAFDA5
我在想一些的WebSphere Web容器的设置可能会阻止容器从正确处理外部请求。或者也许这里有一些课堂加载问题，但是我一直无法找到它。
在WebSphere堆栈跟踪是这样的：

如果任何人都可以点我在正确的方向，请。
WebSphere版本是6.1.0.43。
