我无法在Red Hat Fuse 7.2（或7.3）上使用简单的Daffodil方法进行演示
对我的“ DfdlProcessor.java”处理方法的骆驼DSL路由调用如下所示...
from ("wmq:queue:DEV.QUEUE.1")
.process(dfdlProcessor) <<== failure occurs on this call.
.log("received message: \"${body}\"");
...导致此异常消息...
java.lang.ClassNotFoundException: org.apache.daffodil.util.LogWriter not found by org.apache.daffodil.daffodil-io
我简单的dfdlProcessor的“ process（）”方法看起来像...
public void process(org.apache.camel.Exchange exchange) throws IOException, Exception {
Message inMessage = exchange.getIn();
System.out.println("**** see if can compile DFDL schema");
Compiler dfdlCompiler = Daffodil.compiler(); <<== failure occurs here.
System.out.println("**** done.");
}
（注意：下面进一步显示了Red Hat Fuse 7.2控制台输出的更多内容，即stacktrace）
我的经验是，Red Hat Fuse在组件/版本方面非常脆弱，尽管我花了很多时间/精力，但不幸的是，我在解决此问题方面没有成功。 < / p>
关于我为什么得到...的任何提示
"java.lang.NoClassDefFoundError: org/apache/daffodil/util/LogWriter"
...异常将不胜感激...-头疼，好像我在pom.xml中提供了正确的依赖关系，并将同一jar放在“ deploy”文件夹中
（此外，请注意，当处理器调用-“。process（dfdlProcessor）”被注释掉（禁用）时，该路由会正常工作。）
