Question

我在Tomcat 6上部署了Axis2（1.5.1）Web服务，我正在尝试调用VMware Web Services SDK（JAX-WS服务）。由于我需要维护会话（SESSION_MAINTAIN_PROPERTY = true），因此失败。调用JAX-WS客户端jar时有没有办法绕过Axis2？

这是堆栈跟踪：

<强>问题

问题原来是三重的。第一个问题是过时的Axis2版本（1.5.1），另外两个问题是基于代码的。

<强>解决方案

将Axis版本升级到最新版本（从1.5.1升级到1.7.4）后，以下代码更改解决了问题：

由于Axis2希望会话cookie的名称为JSESSIONID，而VMware返回vmware_soap_session，因此需要设置CUSTOM_COOKIE_ID属性，以便Axis2检测到会话cookie已设置。

VimService vimService = new VimService();
VimPortType vimPort = vimService.getVimPort();

Map<String, Object> ctxt = ((BindingProvider)vimPort).getRequestContext();
ctxt.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, url.toString());
ctxt.put(org.apache.axis2.Constants.CUSTOM_COOKIE_ID, "vmware_soap_session");
ctxt.put(BindingProvider.SESSION_MAINTAIN_PROPERTY, true);

当Axis2维护会话时，它需要第一次调用来设置会话cookie。第一次调用VMware API来检索服务内容不需要会话，因此它不会返回cookie。这里的解决方案是添加另一个VimService和VimPortType，专门用于检索服务内容。完成这些更改后，登录呼叫将起作用。

VimService vimServiceRSC = new VimService();
VimPortType vimPortRSC = vimService.getVimPort();

Map<String, Object> ctxtRSC = ((BindingProvider)vimPortRSC).getRequestContext();
ctxtRSC.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, url.toString());

ServiceContent serviceContent = vimPortRSC.retrieveServiceContent(this.getServiceInstanceRef());
vimPort.login(serviceContent.getSessionManager(), "user", "password", null);

使用随VMware SDK提供的示例代码的片段显示代码更改。
