------------------------------------------
Scott, I am trying to figure out how you did that trick. I am extending
SqlMapDaoTemplate and in constructor trying to get all the names. I am not sure
how you get that sqlMap, which you cast to ExtendedSqlMapClient, to call
getMappedStatementNames.
When I call getSqlMapExecutor() from constructor, I am getting exception listed
below.
java.lang.NullPointerException

> Add functions to fetch sqlmap metadata

> Key: IBATIS-94
> URL: http://issues.apache.org/jira/browse/IBATIS-94
> Project: iBatis for Java
> Type: New Feature
> Components: SQL Maps
> Versions: 2.0.9
> Reporter: Scott Z
> Priority: Minor
>
> I wonder if we can add some getter functions to the SqlMapClient interface
> for the sqlmap metadata information, such as a list of statements, or maybe
> even datasource settings. This information is currently used by us for
> supporting database specific queries and might be useful for others too.
> I know I can get this information if I do something like:
> SqlMapExecutorDelegate delegate =
> ((ExtendedSqlMapClient)sqlMap).getDelegate();
> then call delegate.getMappedStatementNames();
> But I don't want to depend on the implementation just in case it changes.
> Thanks.
