hbm2java comparator class and dependencies

Hibernate version:3

Hi,
I am having trouble generating pojos with hbm2java. One hbm file has a Set element with a sort attribute of my.MyComparator. The set is a many-to-one relationship to another entity in a another hbm that I also wish hbm2java to generate.

hbm2java fails to generate the first entity above as it cannot find the class my.MyComparator, which cannot be compiled until the second entity has its java generated and compiled.

I tried using the <meta attribute="implements" tag to make the second entity implement Comparator and added a meta of "class-code" to implement the compare method. Then setting the class of this entity as the sort attribute on the related entities Set element. This does not work either. Still a problem with class not found.

Any ideas how I can get hbm2java to generate these two related entities when I also need to specify a Comparator?

please put a request in jira with an accompanied sample file that fails.

Hi,

I've got the same issue: I cannot generate POJO object if the comparator is not compiled yet ... and I cannot compile my comparator without the POJO object !

Did someone found a workround ?
I'll look into JIRA to see if this issue is being addressed.

I'll look

Yeah, sorry. Not had time to report it yet. We launch on 6th December so I will have a bit more time to clean house then and can hopefully provide you with an example.

well, i would just need as minimum the stacktrace and how the comparator is specified ....the rest i can manage for this case.

btw. i can see i have a test for it in our unittests and here it does not fail.

what version are you guys using ?

....hm, it will fail (and hard to fix) because i can't get the collectiontype without instantiating the comparator.

you should be able to workaround it via <meta attribute="property-type">java.util.SortedSet<XYZ></meta>

..but let me know in a jira case still

Hi,

I tried the workaround but it didn't change anything.
I'm using Hibernate 3.1. I also tried 3.2 without success.

I'll open a bug in JIRA, with the traces.
