hello Luciano,
i made some changes and now i'm getting another error..maybe the changes are
incorrect. i'm using version tuscany-das-1.0-incubating-beta2, connecting to
an oracle 10g db. below is my table structure.
SQL> describe organization;
Name Null? Type
----------------------------------------- -------- ----------------------------
ORGID NOT NULL NUMBER
ORGNAME NOT NULL VARCHAR2(200)
i changed the orgID from commonj.sdo.IntObject to commonj.sdo.Int, which seems
to have helped. so, now my config file is:
<?xml version="1.0" encoding="ASCII"?>
<Config xmlns="http:///org.apache.tuscany.das.rdb/config.xsd";>
<ConnectionInfo />
<Command name="getAllOrganizations" SQL="select * from ORGANIZATION"
kind="Select">
<ResultDescriptor columnName="orgID" tableName="ORGANIZATION"
columnType="commonj.sdo.Int"/>
<ResultDescriptor columnName="orgName" tableName="ORGANIZATION"
columnType="commonj.sdo.String"/>
</Command>
<Table tableName="ORGANIZATION">
<Column columnName="ORGID" primaryKey="true" generated="true"/>
<Column columnName="orgName" />
</Table>
</Config>
when i make the call to:
DataObject root = read.executeQuery();
this error is thrown...
java.lang.RuntimeException: Table ORGANIZATION in query does not include
Primary Key column or has null value in it, can not proceed!

at hello.HelloImpl.hey(HelloImpl.java:37)
there are 27 records in the organization table and since the orgid is the
primary key, it's never null. i'm assuming the primary key definition is wrong
(maybe not). i tried defining it as commonj.sdo.IntObject but the same error
is thrown.
thx abe

Hey Abraham
I used your config in a simple client app using DAS beta2, and all
seem to work well, so I suspect that there might be some
incompatibility with the actual data type from your table columns. I
was using Derby, and below is the SQL I used to create the
ORGANIZATION table.
CREATE TABLE ORGANIZATION (
orgID INTEGER NOT NULL,
name VARCHAR(50),
primary key (orgID)
);
If you still have issues, please let's work together to solve it. I
might need more info, such as table structure, and DAS/SDO versions
you are using.
