WSO2 DAS 与 Postgres

Question

我正在尝试将 WSO2 DAS 数据源从 H2 更改为 postgres。

我已经在 master-datasource.xml、analytics-datasource.xml 和 metrics.xml

中配置了所有数据库更改

创建事件流时抛出以下异常

java.io.IOException: An exception occurred processing JSP page /eventstream/inner_event_stream_persistence_ui.jsp at line 38

35:     EventStreamPersistenceAdminServiceStub persistenceAdminServiceInnerStub =

37:     if (EventStreamUIUtils.isEventStreamPersistenceAdminServiceAvailable(persistenceAdminServiceInnerStub)) {
38:         String[] recordStoreNames = persistenceAdminServiceInnerStub.listRecordStoreNames();
39:         pageContext.setAttribute("recordStoreNames", recordStoreNames, PageContext.PAGE_SCOPE);
40:     }
41: %>
