WSO2 中的 Lotus Domino Web 服务通过代理服务
Lotus Domino Web Service in WSO2 Pass Through Proxy Service
我在 WSO2 上为 Lotus Domino Web 服务创建了一个直通代理。
这是该服务的 WSDL：

此代理的 WSO2 源视图：
<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"

</target>
<publishWSDL uri="http://firmaa.mis.eu/firmaa/b2b/finanse.nsf/WST1?WSDL"/>
<description/>
</proxy>
问题出在我尝试测试它时（通过 WSO2 测试面板 (tryit)）。测试留言：

使用 HttpSoap12Endpoint 响应是：
<TryitProxyError xmlns:h="http://wso2.org/ns/TryitProxy" h:status="SOAP envelope error">org.apache.axis2.AxisFault:

使用 HttpSoap11Endpoint 响应是：

在 WSO2 服务器控制台上我得到这个：

我注意到没有请求到达 Domino WebService（我根据请求记录了输入值，但日志是空的）。
我不知道问题出在哪里，也不知道如何解决它以使其正常工作...您知道如何处理它吗？
请检查在 firmaa/b2b/finanse.nsf 的 ACL 中允许匿名用户时是否有效。那么你需要解决身份验证问题。
进一步查看 WSDL，我认为 WS 在 Domino 服务器上被定义为 LITERATE 格式，查看 http://www.ibm.com/developerworks/lotus/library/nd7-webservices/ 将其更改为 RPC/encoded。
无需任何身份验证即可访问 Domino Web 服务（在 SOAPUI 中我可以毫无问题地对其进行测试）。
我尝试使用 RPC/encoded wsdl :

但得到相同的 SAXParserException：文件过早结束。
在 WSO2 控制台上出现与以前相同的警告和错误。
我为此 Domino Web 服务编写了一些 java "wrapper" 服务。我发现，我必须设置
options.setProperty(HTTPConstants.CHUNKED, "false");
让这个包装器正常工作。在我得到相同的 SAXParserException 之前。是否有任何 WSO2 属性 将 HTTPConstants.CHUNKED 设置为 false？
已解决。我在 inSequence:
中使用 属性 创建了自定义代理（不是 Passthrough！）
<inSequence>
<property name="FORCE_HTTP_1.0" value="true" scope="axis2"/>
</inSequence>
然后一切正常:)
