this is where it's failing:
if (!root.equals(root.getDataGraph().getRootObject())) {
throw new RuntimeException("'root' argument must be the root of the
datagraph");
}
in org.apache.tuscany.das.rdb.impl.ApplyChangesCommandImpl at line 58 (looking
at the source code). i printed out the same thing and can reproduce the
problem.
the problem is the call to root.getDataGraph() is returning null, thus the call
to root.getDataGraph().getRootObject() throws the npe.
when i make the call to find the organization, the dataGraph is null as well.
here's my call to findOrganization:public
DataObject root =
InputStream in =
getClass().getClassLoader().getResourceAsStream(
DAS das = DAS.
Command read = das.getCommand(
read.setParameter(1, Integer.valueOf(id));
root = read.executeQuery();
DataObject account = root.getDataObject(
System.
System.
}
Output:data graph -> null
then a npe this thrown on the call to:
System.out.println("account dataObject -> "+
account.getDataGraph().getRootObject());
why would the dataGraph be null ?
thx abe

It throws NullPointerException.
Does the organizationService variable have a valid reference to the service?
Try to test this.
You can try to do a dump from organizationService.
Perhaps, organizationService can't find an organization with that id, thus,
returning a null reference.
Check this too.

i put the call to das.applyChanges in a try/catch block which gives a little
more info:

here's line 63 from my test runner:
commonj.sdo.DataObject account =
organizationService.getOrganization(organizationId);
organizationService.updateOrganization(account);
line 63 is organizationService.updateOrganization(organizationId);
thx...hope this helps...all i'm doing is grabbing the org (just a simple find)
in getOrganization, then passing that org to update. no changes are made.
maybe i'm not closing a connection ?

OK, Abraham.
It seems like an invalid reference object in line 63.
What is there?
Can you put here a numbered excerpt of the code around 63 line?

hi, i'm trying to get DAS to work for my service. i'm able to query and get
results back no problem. below is my code for updating. if i take out the
call to account.set(....), then the apply works (but there were no changes to
the DataObject). with the account.set(...) call, the exception is thrown.
ideas? thx abe
Command read = das.getCommand("getAccountByID");
read.setParameter(1, Integer.valueOf(organizationId));
root = read.executeQuery();
DataObject account = root.getDataObject("ACCOUNT[1]");
System.out.println("accountName before change -> "+
account.getString("ACCOUNT_NAME"));
account.set("ACCOUNT_NAME", "TestAccount");
System.out.println("apply changes...");
das.applyChanges(root);
apply changes...Exception in thread "main" java.lang.NullPointerExceptionat
