java.lang.NoClassDefFoundError:oracle/j2ee/ws/common/jaxws/ServiceDelegateImpl

Question

我正在使用 BPM API 来检索分配给特定用户的任务列表。但是，在运行类文件时出现以下错误：--

Exception in thread "main" java.lang.NoClassDefFoundError: oracle/j2ee/ws/common/jaxws/ServiceDelegateImpl
    at oracle.bpm.client.BPMServiceClientFactory.<init>(BPMServiceClientFactory.java:102)

    ... 6 more

我已经将以下 Jar 文件添加到我的项目中：--

1. Oracle.bpm.runtime.jar
2. Oracle.bpm.client.jar
3. Bpm-services.jar
4. Wsclient.jar

但问题仍然没有解决..

有什么建议吗？？？？？？

除了它不工作的原因之外，您应该使用 Oracle 提供的开箱即用的 TaskQueryService。
