> Misleading exception when SDO does not find definition for specific column
> --------------------------------------------------------------------------

> Key: TUSCANY-740
> URL: http://issues.apache.org/jira/browse/TUSCANY-740
> Project: Tuscany
> Issue Type: Bug
> Components: Java BigBank Scenario, Java SDO Implementation
> Affects Versions: Java-M2
> Reporter: Luciano Resende
> Assigned To: Brent Daniel
> Fix For: Java-M2

> While working on Bigbank, was getting the following exception :
> Exception in thread "main" java.lang.NullPointerException

> at bigbank.account.services.accountdb.AccountDBInit.main
> (AccountDBInit.java:466)
> This was due to a mismatch between data returned from the query and the
> generated DataObject model. The query in this case is doing "select *
> from stocks", which will return columns ID, Symbol, Quantity,
> purchasePrice, purchaseDate, and purchaseLotNumber. The wsdl used to
> generated the SDO model doesn't have an ID column. Looking at
> AccountDBInit, it looks like ID is supposed to identify a customer.
> Nothing in the StockSummary type in the wsdl looks like it corresponds
> to this.
> Regardless, we need to return a meaningful exception for this rather
> than the NPE from SDO.
