 Post subject: middlegen generated mapping and source file problem

I started this in another thread, but was recommended to create new thread- good idea...

here is problem - which i have subsequently solved - question is, why is the meta attribute element within composite-id element not legal, and if it is, why is it not loading the mapping?

The middlegen hbm mapping generation task creates a <meta attribute> element within the <composite-id> element. This does not appear to be legal. i believe i am using hte latest middlegen and i know i am using the 2.0 hibernate dtd from sourceforge - the top of the stack trace relevant to this error is:

2004-03-03 09:13:18,988 ERROR [TP-Processor2] cfg.Configuration (Configuration.java:276) - Could not configure datastore from
input stream
java.lang.NullPointerException
at net.sf.hibernate.util.StringHelper.qualify(StringHelper.java:239)
at net.sf.hibernate.cfg.Binder.bindComponent(Binder.java:734)


and in next stack it says:

2004-03-03 09:13:19,039 ERROR [TP-Processor2] cfg.Configuration (Configuration.java:248) - Could not compile the mapping docu
ment
net.sf.hibernate.MappingException: duplicate import: Eventgiftbundle

i am not sure what the exact issue is, but if i remove the meta attribtue tag, it goes away - ie, the class loads.

can you post to JIRA a simple testcase showing that. The meta attribute is supposed to be allowed.

jira? can you please give url or expl? i would love to help and resolve this. here is my composite-id element with the meta attribute - maybe there is something wrong with the meta-attribute?

Code:
    <composite-id name="comp_id" class="com.lupinex.pate.db.EventgiftbundleelementPK">
        <meta attribute="class-description" inherit="false">
           @hibernate.id
            generator-class="assigned"
        </meta>
        <!-- bi-directional many-to-one association to Giftelement -->
        <key-many-to-one
                name="giftelement"
                class="com.lupinex.pate.db.Giftelement"
            >
            <meta attribute="field-description">
               @hibernate.many-to-one
                column="giftelementid""
            </meta>
            <column name="giftelementid" />
            </key-many-to-one>
        <!-- bi-directional many-to-one association to Event -->
        <key-many-to-one
                name="event"
                class="com.lupinex.pate.db.Event"
            >
            <meta attribute="field-description">
               @hibernate.many-to-one
                column="eventid""
            </meta>
            <column name="eventid" />
            </key-many-to-one>
        <!-- bi-directional many-to-one association to Giftbundle -->
        <key-many-to-one
                name="giftbundle"
                class="com.lupinex.pate.db.Giftbundle"
            >
            <meta attribute="field-description">
               @hibernate.many-to-one
                column="giftbundleid""
            </meta>
            <column name="giftbundleid" />
            </key-many-to-one>
    </composite-id>

if i remove the first meta attribute element (the one for composite-id) the mapping loader continues - if i leave it, it throws the error i mention.

I found jira - i will hold off as i am sure this is user error somehow - though if you see nothing wrong with my composite-id declaration, then i will try to work up a simple test case - what would be involved in a test case: a java class, the mapping file, and ??

thank you

What are you doing there, what are all these @ things? This is not a legal mapping file, please look at some tutorials and examples.

okay - this was all generated for me by middlegen. i don't mean to waste anyone's time, so, i will just remove the meta tags. all the existing tutorials are for trivial examples and none that i can find use the exact primarykey paradigm that was setup for me by middlegen. middlegen decided to create a PK class for me and created this mapping.

i will say that hte META tags inside the key-many-to-one and property elements are not a problem - so, i would not know that those in the composite-id element are.

i will remove for now, just looking for ideas. i have read a lot about this, read about the auto-import flag in the mapping element and other possible solutions, but no one discusses this problem i have with the middlegen-generated element.

thanks for your input.

Oh sorry, I did not look close enought, in fact this should be legal ... Could you post a more complete stacktrace? You are using Hibernate 2.1.2 ?

stack trace starting when it tries to parse(?) the Eventgiftbundleelement mapping file - as an aside, these debug message are based on log4j settings - which file am i to edit to change the 'level' of information?

as i have said, if i remove the single META element from composite-id, this error does not happen - as you can see, this also stops the entire processing - i have 10 other hbm files to process after this one - and if i remove the META tag it continues processing, until it hits another class that has a META tag in a composite-id

I think you are using an old version, this should be fixed in 2.1.2

thank you - i thought i downloaded the most recent. i guess not.

is there a way to determine a version from a jar - is it in a META-INF file or something?

either the version at the end of the .zip distribution file or in the hibernate log when Hibernate initialize itself.

This is fine - but you need later version of hibernate as the DTD has had a number of changes over its beta period (still called 2.0 for backward compatibility).
