Hello guys,

I’m executing Xdoclet against a very simple class and I’ve found two errors during the generation of the mapping file.

The first was related with the “type” attributo in the “id” element. For some reason, xdoclet claims if you specified it, in my case along the “generator-class=sequence”.

Now, I have another different. This time myeclipse claims against the mandatory use of the “access” and “unsaved-value” of the “version” element. What it’s astonished is the fact these attributes are present in the mapping file.

        <version
            name="version"
            type="integer"
            column="VERSION"
            access="property"
            unsaved-value="null"            
        />

2 Attribute “access” must be declared for element type “version”. Role.hbm.xml
2 Attribute “unsaved-value” must be declared for element type “version”. Role.hbm.xml

If I remove these two attributes the errors disappear from the problems console, but they are mandatory indeed.

Any idea?

TIA,

Roque

1) What does the class look like?
2) Where are the errors? In the XDoclet console when you run it?

[rcaballeron]

In the first problem the error appeared on the Xdoclet console, the second appear in the eclipse editor. You know, with red marks and in the problems window as well.

I’m was testing a little and I think is something related with the Hibernate DTD used in the mapping xml. Is it possible to chose a different one?

By the way, is it possible to chose a output directory for the mapping files?

If you are doing this xdoclet work yourself, yet you can specify the version to use by editing the hbiernate doclet and setting the version to 2.0, 2.1 or I think 3.0 is supported as well. Also the “output” field specifies the output dir.

If you are doing this mapping through the MyEclipse Hibernate mapper, let me know because right now as I understand it you are doing it yourself by running XDoclet against your classes.

[rcaballeron]

I’m using the XDoclet facility instead of the Hibernate mapper because, AFAIK, the m:n relationships aren’t mapped properly.
