[jira] Updated: (DERBY-1075) Combine the script and the test
available for upgrade testing into a java test
[ http://issues.apache.org/jira/browse/DERBY-1075?page=all ]
Deepa Remesh updated DERBY-1075:
--------------------------------
Attachment: loader.java
I have written a small java program 'loader.java' to test that I can load different version of derby classes using a classloader. After loading a particular version of Derby, I get a connection and check the product version in the connection metadata. I found that I can switch between versions without problems. I also checked that the classloader ignores the settings in the class path and uses only what is specified in the program. So all the following commands result in same output:
1. java -classpath . loader C:\deepa\Derby\10.1\classes C:\deepa\Derby\trunk\classes
2. java -classpath .;C:\deepa\Derby\10.1\classes loader C:\deepa\Derby\10.1\classes C:\deepa\Derby\trunk\classes
3. java -classpath .;C:\deepa\Derby\trunk\classes loader C:\deepa\Derby\10.1\classes C:\deepa\Derby\trunk\classes
However, I found I cannot use DriverManager to get a connection. The reason I think is this statement from the javadoc "When the method getConnection is called, the DriverManager will attempt to locate a suitable driver from amongst those loaded at initialization and those loaded explicitly using the same classloader as the current applet or application.". Use of DataSource to get connection works fine. I hope it is okay to proceed by using DataSource. I would appreciate if someone can take a quick look at the attached program and let me know if this is the right direction.

> Separating a part of DERBY-514 into a sub-task. This sub-task is to combine the script 'runphases.ksh' and the java file 'phaseTester.java' into a single java test. This will help to later add the upgrade tests into the regression suite. Also, this sub-task can be done independent of DERBY-1049 which is blocking DERBY-514.
