这里描述了类似的问题:GWT IllegalArgumentException: encodedRequest cannot be empty
我的 GWT 应用程序部署在 Tomcat6 中,它通过使用 Coyote/JK2 连接器与 Apache 链接。对于 SSO,我使用 mod_auth_sspi/1.0.4。
当我使用 IE8 时,页面不显示,但对于 Firefox 一切正常。在 Tomcat 日志中,我看到以下内容:
SEVERE: Exception while dispatching incoming RPC call

到目前为止我尝试了什么:
1)找不到注册表项DisableNTLMPreAuth
(恕我直言,这不是解决方案,因为在我的情况下,IE 8 被积极使用)。
2) 我已经安装并配置了 Native Windows Authentication Framework WAFFLE
网页.xml:
...
<filter>
<filter-name>NegotiateSecurityFilter</filter-name>
<filter-class>waffle.servlet.NegotiateSecurityFilter</filter-class>
<init-param>
<param-name>waffle.servlet.spi.NegotiateSecurityFilterProvider/protocols</param-name>
<param-value>NTLM</param-value>
</init-param>
</filter>
...
<filter-mapping>
<filter-name>NegotiateSecurityFilter</filter-name>
<url-pattern>/my-app/*</url-pattern>
</filter-mapping>
...
但这并没有帮助。
3)在worker.properties
我设置socket_keepalive=0
,但它也没有帮助 -
worker.ajp13.type=ajp13
worker.ajp13.host=localhost
worker.ajp13.port=8009
worker.ajp13.lbfactor=50
worker.ajp13.cachesize=10
worker.ajp13.cache_timeout=600
worker.ajp13.socket_keepalive=0
worker.ajp13.socket_timeout=300
我还能尝试做什么?
