I’ve been trying to setup an HQL editor against a cleanly generated hibernate reverse engineered schema. I have been successful in the past before with other projects, but
I’ve tried this against several databases across different MyEclipse versions, including the 6.5 M1 release, and got the same results. The error occurs when I open the HQL editor,Unable To create SessionFactory, Reason org.Hibernate.type.StringType

Any ideas what could be causing this?

Thanks,
Chris

The error I get in the MyEclipse log is below

Are you trying to run the HQL editor though a batch file?

[cpalm72]

I’m trying to run the HQL editor by right clicking on the project, selecting Myeclipse, then open HQL Editor. The first time I do this I get that error. Subsequent HQL editors I open, the error doesn’t come up until I type in a statement and attempt to run it.

Did you setup MyEclipse using the All in One installer? I would like you to switch to a new workspace (File > Switch Workspace > Temp), create a new hibernate project and try opening the HQL editor. Do you get the same error?

Yes, I had used the all in one installer with the 6.5 release also, and setup a project in a new workspace. The trace information I posted in the original
email was from one of my earlier attempts on the 6.0.GA release. This seems to consistently happen, at least with these sets ot tables.
I can however, get this to work on the Apache Derby tables that come with the IDE.

cpalm,

I would expect this sort of error to cause problems in your Hibernate application as well, but I assume that is working without a problem?
I’m assuming this is a simple Hibernate project with Hibernate mapping files.

Are you using <version> and / or <timestamp> elements in any of your mapping files, that is where the problem seems to be. Can you try removing them and see if the problem goes away?
To help narrow down the issue, you could try creating a new test project with the smallest number of tables required to reproduce the issue. If you can send us the DDL for the tables involved or a snippet of mapping file where you are using the version mapping, we will take a look at it.

Sorry for the inconvenience caused.
