我已经部署了带有AS4模块的Oxalis实例。
OS : Ubuntu 18.04
JDK : openjdk version "1.8.0_222"
Oxalis : v4.0.4
Oxalis-AS4: Oxalis-AS4 RC8
在调用http://localhost:8080/oxalis/as4时收到正确的响应（Hello AS4 World）。
但是当我尝试使用oxalis-standalone.jar将文件发送到AS4终结点并在类路径中包含oxalis-as4 jar文件时，oxalis-standalone会产生以下错误。它还显示仅部署了AS2传输配置文件。

我已将此部署在两台计算机上，并产生相同的结果。
什么会导致此问题？预先感谢您的支持！
关于，哈尔沙
似乎您不对草酸单罐使用AS4扩展。因此，您没有将罐子提取到文件夹中，或者在调用oxalis-standalone.jar使用该文件夹时没有更改类路径。请在https://github.com/difi/Oxalis-AS4处查看README.md。
推荐的结构如下：
├── standalone/ <-- We will putt our regular Oxalis Standalone application here...
│ ├── oxalis-standalone.jar
│ ├── posibly-other.jar
│ └── ...
└── as4/ <-- ...and our AS4 extension here
├── oxalis-as4.jar
├── many-other.jar
└── ...
命令如下所示：
java -classpath "standalone/*;as4/*" eu.sendregning.oxalis.Main [followd by the argument like -f c:\some-invoice.xml]
然后，以下内容应出现在您的日志中-表示支持AS4：
INFO [no.difi.oxalis.outbound.transmission.MessageSenderFactory] => peppol-transport-as4-v2_0
INFO [no.difi.oxalis.outbound.transmission.MessageSenderFactory] => busdox-transport-as2-ver1p0r1
INFO [no.difi.oxalis.outbound.transmission.MessageSenderFactory] => busdox-transport-as2-ver2p0
INFO [no.difi.oxalis.outbound.transmission.MessageSenderFactory] => busdox-transport-as2-ver1p0```
