Websphere 5.0 does not support MySQL as a 5.0 datasource???

[Claes Bergsten]

What is this DataStoreHelper thing required?
Cant find it in any specs is it WS specific?
If so is there one for mySQL?

I tried using both:
com.ibm.websphere.rsadapter.WSConnectJDBCDataStoreHelper
and
com.ibm.websphere.rsadapter.ConnectJDBCDataStoreHelper

But they give this error:

IBM has implemented JDBC as J2C Resource Adapters. The way that it
works, from what I have gathered is that the DataStoreHelper classes
handles the connection pooling mechanisms. When a call to
DataSource.getConnection is called the class
com.ibm.rsadapter.jdbc.WsJdbcRsaDataSource (or something similar,
doing this off the top of my head) instantiates an instance of the
class who's name you set up in the Data Provider configuration.

Now as for MySQL, my understanding is that there is not a Helper class
as of yet. No idea if anyone is building one.

Hope this helps at least explain what is happening with WASv5
