WSO2 BPS WS Bpel编译错误处理变量

嗨（对不起，我的英语不好）

我正在使用Wso2 Developer Studio构建一个Bpel工作流，在我的工作流中，我需要调用多个Web服务，根据这些服务的输出采用不同的路径，为此我需要使用变量，但是，当我在wso2 bps中部署工作流流程时，我遇到了编译错误：文件上载失败：BPEL编译失败

我搜索了一下，有人说这是一个名称空间问题，但我不知道如何解决这个问题，请帮忙。下面是错误和bpel源代码

错误表明，编译器无法解析xsd数据类型，这在默认情况下是可能的。对我来说，这更像是发动机的问题。这并不重要，但是您可以尝试显式定义默认名称空间（add

xmlns=）http://docs.oasis-open.org/wsbpel/2.0/process/executable“

到您的流程中）。此外，还可以将

xmlns:xsd

定义为非xsd的内容。你能试着删除它吗？谢谢你的回答…xds是由IDE添加的，当我导入需要调用的Web服务的wsdl时，如果我删除它，我会在IDE中出错，我尝试更改xds的名称，但是我得到了相同的编译错误。我也尝试添加xmlns=，但IDE报告了更多错误。我在IntelliJ中通过模式验证运行了您的过程，它说您应该从

literal

元素中删除

xml:space

，但我怀疑这是否会导致错误。在我看来，您的变量定义很好，因此您得到的编译错误毫无意义。如果你在这里找不到帮助，你应该试试wso2邮件列表。
