[jira] Updated: (HARMONY-4197)
[classlib][sql]SyncFactory.getInstance cannot find the providers that are
in the default package
[ https://issues.apache.org/jira/browse/HARMONY-4197?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ruth Cao updated HARMONY-4197:
------------------------------
Attachment: Harmony-4197.diff
May somebody pls try this?
Since the SyncFactory has no test cases now, I'll add the test cases when the implementation of default providers are finished. Thanks a lot.

> SyncFactory.getInstance(String) is not able to return the providers which are in the default package. The following test case shows this problem:
> public class SyncFactoryTest {
> static String providerName = "DummyProvider";
> public static void main( String args[] ) {
> try {
> System.out.println("Provider name is " + providerName);
> SyncFactory.registerProvider(providerName);
> System.out.println("Provider registered.");
> SyncProvider provider = SyncFactory.getInstance(providerName);
> System.out.println("Got Instance of Provider.");
> if( provider == null ) {
> System.out.println("That shouldn't have happened. The provider is null");
> } else {
> System.out.println("Provider retrieved is " + provider.getProviderID() );
> }
> } catch (Exception e) {
> System.out.println("Caught an exception!");
> e.printStackTrace();
> } finally {
> System.unregisterProvider(providerName);
> }
> }
> }
> public class DummyProvider extends SyncProvider {
> public String getProviderID() {
> return getClass().getName();
> }
> public String getVendor() {
> return "Me";
> }
> public String getVersion() {
> return "2.0";
> }
> public int supportsUpdatableView() {
> return 0;
> }
> public int getDataSourceLock() {
> return 0;
> }
> public void setDataSourceLock( int i ) {}
> public int getProviderGrade() {
> return 0;
> }
> public RowSetWriter getRowSetWriter() {
> return null;
> }
> public RowSetReader getRowSetReader() {
> return null;
> }
> }
> RI prints: Provider retrieved is DummyProvider
> while Harmony prints: Caught an exception! javax.sql.rowset.spi.SyncFactoryException: ClassNotFoundException: DummyProvider
> ...
> It seems that the way Harmony looks for the provider class is different from RI. I'll create a patch for this soon, thanks.
