Hi,
I am trying to fetch details of a manufacturer from Database but I am getting an error
java.lang.ClassCastException: com.konakart.om.Manufacturers cannot be cast to com.workingdogs.village.Record
My code is
KKCriteria manufacturerCriteria = new KKCriteria(Torque.getDefaultDB());
manufacturerCriteria.add(ManufacturersPeer.CUSTOM3, manufacturer.getManufacturerCode());
List<Record> manufacturers = ManufacturersPeer.doSelect(manufacturerCriteria);
if(manufacturers.size() > 0) {
Record manufacture = manufacturers.get(0); Getting error at this line.
manufacturerCriteria.clear();
return manufacture.getValue(ManufacturersPeer.MANUFACTURERS_ID).asInt();
} else {
manufacturerCriteria.clear();
return -1;
}
Can you please help me out
Yes that's not a valid cast.
You should use the APIs wherever possible. Check the KKEngIf interface in the javadoc - if you've installed KonaKart you can see the javadoc at http://localhost:8780/javadoc/ (http://localhost:8780/javadoc/)
eg.. http://localhost:8780/javadoc/server/com/konakart/appif/KKEngIf.html (http://localhost:8780/javadoc/server/com/konakart/appif/KKEngIf.html)
About the javadoc....
The advantage of going to localhost to view it is that it's more likely to match the version you are currently using and that it's local.
However, the javadoc for the latest public release is also available online at:
http://www.konakart.com/documentation/javadoc (http://www.konakart.com/documentation/javadoc)
I tried having a look into the javadoc. However I want to get the manufacturer based on a custom field and not by name or id. I could not find any method in KKAdminEng. Also is there any programming guide other than the user guide for Konakart ?
Secondly, I am trying to create jobs in konakart. Is it possible to run jobs thorough command line rather than using quartz. Quartz is a good job scheduling mechanism but has an disadvantage over monitoring. Also are there any examples for jobs in Konakart distribution.
Sorry for asking too many things in a single go :D
We have added a much more flexible Manufacturer search API in the next version (out early in the New Year).
For now, you could try something like this to retrieve Manufacturers and instantiate Manufacturer objects:
List<Record> rows = BasePeer.doSelect(c); // c is the Criteria object
Manufacturer[] retArray = new Manufacturer[rows.size()];
int i = 0;
for (Iterator<Record> iter = rows.iterator(); iter.hasNext();)
{
Record row = iter.next();
Manufacturer m = new Manufacturer(row, c); // c is the Criteria object
retArray[i++] = m;
}
We provide some utilities and examples for running KonaKart-related batch jobs in Quartz - in our Enterprise version.
