【问题描述】：
我创建了一个使用 DB（在我的例子中是 Oracle DB）的 BIRT 报告模板。 查询是这样的：
SELECT Something, Quantity FROM SOMETABLE WHERE Like ?
从 Eclipse（用于 BIRT 报告）一切正常。问题是我想创建一个可以完成这项工作的 Web 服务。 所以我尝试像这样传递连接：
Connection conn = null;
try {
DriverManager.registerDriver((Driver) Class.forName("oracle.jdbc.OracleDriver").newInstance());
conn = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:name","user","pass");
} catch (SQLException | InstantiationException | IllegalAccessException | ClassNotFoundException ex) {
// handle any errors
System.out.println("SQLException Message: " + ex.getMessage());
}
task.getAppContext().put("OdaJDBCDriverPassInConnection", conn);
task.getAppContext().put("OdaJDBCDriverPassInConnectionCloseAfterUse", false);
我得到：
Caused by: org.eclipse.birt.data.engine.odaconsumer.OdaDataException: Failed to prepare the following query for the data set type (org.eclipse.birt.report.data.oda.jdbc.dbprofile.sqbDataSet).

我在网上找到的都是：https://bugs.eclipse.org/bugs/show_bug.cgi?id=360702 但它并没有真正帮助我，我不确定我是否了解 cmets。
有人可以帮我吗？代码示例会很好。
