Larry,
Thanks
for the suggestion.
I
looked at the DataSourceFactory. The method getDataSource() does not take any
parameters. The flow of our application is like this:
1 -
Contact the system datasource and get a list of all companies and their
associated datasource jndi names
2 -
When the user logs in, we get its company id and using it as a key we find the
corresponding datasource jndi name
3 -
The company datasource jndi name is then returned and used for all
connections.
What
seems like a good solution is to extend the JNDIDataSourceFactory and overload
the method getDataSource so that it can accept a company id as an argument:
getDataSource(int companyId). Internally, we have a map of companyid (key) and
datasource name (value).
However, what I can't figure out is where that method is actually called
in iBatis.
Thanks,
-
Adnan

Each customer database is mapped to a different datasource. In iBatis we have to hardcode the JNDI name for the datasource in the sql-map-confi.xml file. Is there anyway to make this dynamic? In other words, I want to query the customer datasource name (the names are stored in the system database) at run time based on the user id, and then use that name for getting my connections.Any help is greatly appreciated.
