我需要编写一个java代码来使用API在Weblogic中创建数据源。我从Weblogic找到了一个API。但我无法找到任何示例实现。有人可以帮我吗？我正在尝试使用以下API：
DataSourceManager dsManager = DataSourceManager.getInstance();
dsManager.createAndStartDataSource(jdbcImpl, appName, moduleName, compName, jdbcCtx, classLoader)
提前致谢。

您需要对该操作使用WLST脚本接口管理，如该片段中所述：

16: interpreter = new WLSTInterpreter();
17: this.weblogicUserName = weblogicUserName;
18: this.weblogicPassword = weblogicPassword;
19:
20: }
