I have a query:
select p from Product p
Which gives me the results I expect, but one of the columns (let's call it massiveDescription
) is big, and since I'm querying the full list of products I want to exclude it.
I added @Basic(fetch=FetchType.LAZY)
to getMassiveDescription()
but this made no difference (the generated sql still includes all columns).
I'm using glassfish pretty much out of the box, and it uses toplink essentials. I thought there might be something I had to do to configure the agent, so I tried adding -javaagent:/path/to/toplink-essentials-agent.jar
in the JVM options through the glassfish web interface. Then I get an exception:
java.lang.NoClassDefFoundError: javax/transaction/Synchronization
at ...
So I figure I need to add jta.jar
to the classpath suffix box in the glassfish web ui. That gives me a different exception:
java.lang.NoClassDefFoundError: oracle/toplink/essentials/transaction/JTASynchronizationListener
at oracle.toplink.essentials.transaction.JTATransactionController.<init>...
So now I'm chasing jars. I add toplink-essentials.jar
to the classpath in the same way, but I still get the same exception.
I have a few questions:
select p
for select p.id, p.name, ...
gives me strange errors - but I was only guessing at the syntax anyway. Turns out toplink essentials doesn't support this. Eclipselink does, so looks like I'm moving ORMs.
