Amita Vadhavkar commented on TUSCANY-1355:
------------------------------------------
This might be imcompatibility in SDO, not sure, will you please list here all
the sdo and das jars
(exact with versions) you are using?
Also, will you please check using RDB DAS beta1 binary distribution at
http://people.apache.org/~lresende/tuscany/das-beta1-distribution/ instead of
building it from scratch, please use all the same jars provided in there.
Regards

> Key: TUSCANY-1355
> URL: https://issues.apache.org/jira/browse/TUSCANY-1355
> Project: Tuscany
> Issue Type: Bug
> Components: Java DAS RDB
> Affects Versions: Java-DAS-M2
> Environment: DAS-RDB to access the database of Oracle
> Reporter: wangful
>
> I have used the following simple codes to use DAS to access an Oracle
> database.
> //String url =
> "jdbc:db2j:D:/RAD6/runtimes/base_v6/cloudscape/DAS";
> String url = "jdbc:oracle:thin:wcs/wcs1@//raptor08:1521/g10";
> String query = "select * from MYCUSTOMER";
> String query_result="";
> Connection conn = null;
> // Class.forName("com.ibm.db2j.jdbc.DB2jDriver").newInstance();
> DriverManager.registerDriver(new
> oracle.jdbc.driver.OracleDriver());
> conn = DriverManager.getConnection(url);
> conn.setAutoCommit(false);
> DAS das =
> DAS.FACTORY.createDAS(conn);
> Command readStores = das.createCommand(query);
> DataObject root = (DataObject)readStores.executeQuery();
> DataObject cus1 = root.getDataObject("MYCUSTOMER[1]");
>
> System.out.println(root.getInt("MYCUSTOMER[1]/ID"));
> System.out.println(root.getString("MYCUSTOMER[1]/NAME"));
> It will caused the following error:
> Exception in thread "main" java.lang.IllegalArgumentException: Class
> 'DataGraphRoot' does not have a feature named 'MYCUSTOMER'
> at

> at
> org.apache.tuscany.sdo.impl.DataObjectImpl.getDataObject(DataObjectImpl.java:326)
> at TestDAS.main(TestDAS.java:47)
> But the same code and same config will work well for cloudscape database.
> There are also some other problems for Oracle, seems DAS can't work for
> oracle.
> Will someone look into this problem?
> Thanks.
