Hi,
Here are two patches that add simple failover support to the jdbc driver.
Patch 1 converts all references to pair of host+port variables to single InetSocketAddress
Patch 2 rewrites the url parsing to support multiple host:port pairs and modifies the low level connection opening to retry once all listed addresses
I also added more cases to the unit tests to verify that I did not break any functionality.
* The connection url and connection parameters stay backwards compatible
* If there are commas in the hostname part of the url the new code will use them to split the addresses and keep them in the defined priority order
* If there is any IOException or login failure during the connection phase the code will try another listed address
* I tried to keep the code still Java 1.4 compatible
