Hibernate version: middlegen-r5

Mapping documents:
<?xml version="1.0"?>

<!--
This is a testing platform for the middlegen hibernate plugin. It is a stripped
down version of the samples application. At the moment it is only concerned
with the generation of the mapping documents so that various tests etc can be
done on the generated package.

The DOCTYPE declaration declares the location of product-specific parts of the
Ant build file. You can change the values of these declarations to point to
other available files. This gives you an opportunity to choose what database.

Note that this syntax has nothing to do with Ant or Middlegen. This
is the standard way defined by w3c to dynamically include external
files in an XML document. Any decent XML parser will do the include
transparently. Try to open this file in Internet Explorer and see
for yourself.

If you want to generate XDoclet markup for hbm2java to include in the POJOs then
set genXDocletTags to true. Also, composite keys are generated as external classes which is
recommended. If you wish to keep them internal then set genIntergratedCompositeKeys to true.
Since r4 the ability to customise the selection of JavaTypes is now provided. The is a
recommended type mapper provided as shown. It is optional - if not provided then Middlegen
itself will select the Java mapping (as it did previously).
These settings are optional thus if they are not define here values default to false.

Debug level Hibernate log excerpt:

It appears that the Hbm2Java class is missing? See the console ouput from my ant task.

I ran middlegen previously and it created 5 hbm.xml files. When i exit out of middlegen nothing else happens. So i ran the hbm2java ant command task...

Am i missing something? I looked in all of the jar files I have and I don't see the class in there.

C:\middlegen>ant hbm2java
Buildfile: build.xml

hbm2java:

BUILD FAILED
C:\middlegen\build.xml:217: taskdef class net.sf.hibernate.tool.hbm2java.Hbm2J
aTask cannot be found

Total time: 1 second

i made a cut and paste error the hb2java section of my build.xml file is actually this:




I still get the error. In the original posting i was messing around with the build.xml file trying to get it to work and find the Hbm2javaTask

I resolved the issue. there were some missing .jar files that were missing. I just redownloaded.

I don't supply hibernate or the extensions library jars with the R5 (or earlier) releases. I have assumed that you would have them already and it makes the package smaller. Maybe I should include them. What do people think?

Yes, the jars should be included. The extra time of the download is significantly smaller than trying to figure out how to fix it. I would rather the jars be included and worked out of the box.

Ben

I can't agree more!
It's more convenient for users to download the main jar and extension jars together.

OK [assuming I remember] R6 will include the latest Hibernate (stable) release jars and extensions [but only enough libs to generate the Java POJO using hbm2java]
