Subject [jira] Updated: (DERBY-648) ij 'show connections' statement does not work in JSR169
Date Wed, 26 Oct 2005 22:56:55 GMT
     [ http://issues.apache.org/jira/browse/DERBY-648?page=all ]

Deepa Remesh updated DERBY-648:

    Attachment: derby-648.diff

Attaching a patch 'derby-648.diff' for this. The patch does the following:

1. Checks if ij.dataSource property is set in 'showConnectionsMethod' in ij. If it is set,
URLs are not displayed. Only connection names are displayed. When DataSource is used to get
a connection, there will not be an associated URL.
2. Enables 2 tests in J2ME which pass with this change. Creates new master files for these

Ran derbyall on Windows XP with Sun JDK 1.4.2 and IBM WCTME5.7 j9_foundation VM. No new failures.

"Show Connections" command is documented in Derby Tools and Utilities Guide. However, ij.dataSource
property is not yet documented. DERBY-391 is open for this. I will add doc information for
this change to DERBY-391.

> 'show connections' statement throws the following exception when run in CDC/FP with JSR169:
"JAVA ERROR: java.lang.NoSuchMethodError: java/sql/DatabaseMetaData.getURL()Ljava/lang/String;"
> This is because java/sql/DatabaseMetaData.getURL() method is not available in JSR169.
In JSR169, DataSource has to be used to get a connection and this does not use a URL. So this
method is not available.
> Currently, 'show connections' displays connection names along with the URLs used to get
the connections. When DataSource is used to get connection (ij.dataSource property is set),
I plan to change this to display only connection names. With this change, around 7 tests can
be enabled to run in CDC/FP.
