> Key: TUSCANY-1434
> URL: https://issues.apache.org/jira/browse/TUSCANY-1434
> Project: Tuscany
> Issue Type: Bug
> Components: Java DAS RDB
> Affects Versions: Java-DAS-beta1
> Reporter: Ron Gavlin
> Fix For: Java-DAS-Next

> I am attempting to use das.applyChanges() to insert a row into the CUSTOMER
> table. My augmented "basicCustomerMappingWithCUD2.xml" file includes a
> "ConnectionInfo" element with a "datasource" attribute specified. Note below
> that I am using static SDO without invoking the standard priming
> das.getCommand("command").executeQuery() before invoking das.applyChanges().
> When I execute the following code snippet, I receive an error in
> das.applyChanges() that there is no database connection currently open.
> DAS das =
> DAS.FACTORY.createDAS(getConfig("basicCustomerMappingWithCUD2.xml"));
> DataGraph dg = SDOUtil.createDataGraph();
> dg.getChangeSummary().beginLogging();
> dg.createRootObject(TypeHelper.INSTANCE.getType(Customers.class));
> Customers customers = (Customers) dg.getRootObject();
> Customer customer = CustomerFactory.INSTANCE.createCustomer();
> customer.setID(9999);
> customer.setLASTNAME("Jones");
> customers.getCustomer().add(customer);
> // FIXME the following line is required to workaround this DAS bug
> // whereby no connection exists w/out a priming
> getCommand().executeQuery()
> // Note that the following line should be removed in this test code
> after the patch for this bug is applied
> ((DASImpl) das).getConnection();
> // end of FIXME
>
> das.applyChanges((DataObject) customers);
> The proposed patch for this bug is as follows:
> org.apache.tuscany.das.rdb.impl.DASImpl.class
> Change line 114 FROM
> Line 107
> /*
> * (non-Javadoc)
> *
> * @see org.apache.tuscany.das.rdb.CommandGroup#getApplyChangesCommand()
> */
> public ApplyChangesCommandImpl getApplyChangesCommand() {
> ApplyChangesCommandImpl cmd = new
> ApplyChangesCommandImpl(configWrapper, connection); // Line 114
> return cmd;
> }
> TO
> Line 107
> /*
> * (non-Javadoc)
> *
> * @see org.apache.tuscany.das.rdb.CommandGroup#getApplyChangesCommand()
> */
> public ApplyChangesCommandImpl getApplyChangesCommand() {
> ApplyChangesCommandImpl cmd = new
> ApplyChangesCommandImpl(configWrapper, getConnection()); //Line 114
> return cmd;
> }
> FYI, the customer.xsd for this test was augmented to include the "Customers"
> complex type as follows:
> <xsd:complexType name="Customers">
> <xsd:sequence>
> <xsd:element name="customer" type="Customer" maxOccurs="unbounded"
> />
> </xsd:sequence>
> </xsd:complexType>
> Let me know if you have questions.
