Process polling records in bpelx:exec help

Question

I have a process which polls the database table for new records. After getting the new database records, i like to pass all records to a process activity called 'Java embedding'. I have to do this because i have to concatenate a column (called file_name) for all records and put in into a queue. The problem is I don't know how to generate java classes for the database table so that I can retreive polling records in the <bpelx:exec> before i can concatenate them and then put them into the queue. I don't know if i have to do any additional setup to get the java classes generated.
Please help,
thanks

Answer 1

I already found out how to do it. But I have another problem.
I could not retrevie the from <bpelx:exec> using the code below:
Element element = (Element) getVariableData("vinDecoderInput");
IVinTranslationsCollection requests =
IVinTranslationsCollectionFactory.createFacade(element);
List vinTranslations = requests.getIVinTranslations();
int count = vinTranslations.size();
addAuditTrailEntry("count is " + count);
The count always equals to 0.
It is not working for what looks like a bug in b2 in java.
Does anybody has any idea about it?
thanks,
