It seems that Hibernate.id tag does not support the nested column tag. Is there away to get around this. I did see that there this issue raised in the JIRA, but haven't come across any solution. Any tips, hints??

Thanks

No. Embeded composite keys are not implemented in Xdoclet (as yet). You can have external composite key classes (which is the recommended approach). The Key properites are Xdoclet hibernate properties on the methods of the class that represents the composite key.

Aagh...I meant using the column tag to define the sql type within the id tag. Eg. For Long, the default is NUMBER(19,0) that gets created by the xdoclet. I would like to change this to NUMBER(15,0). The only way to do this is to use the column tag withing the id.

Thanks

OK now I understand.
XDoclet markup mirrors the mapping XML DTD in that there is no attribute for sql-type for the id property. In this case you do need to use the nested column tag to set this option. So no workaround since Xdoclet is following hibernate's features.

I have been assuming that you have used both the @hibernate.id and the @hibernate.column (for nested tag generation) for your id Xdoclet markup. You just did not like the solution. This does work and addresses your issue (unless you did not want two @hibernate markup lines for the id property).

I did try

@hibernate.id
------
@hibernate.column
-----

assuming that it would generate something like this (as it does for the other properties in conjunction with @hibernate.property)

<id name = "aaa" ...... >
<column ....../>
</id>

But does not work that way. However, i can hand edit the mapping file and create the proper schema.

The JIRA issue that I am talking about is:


http://opensource.atlassian.com/projects/xdoclet/secure/ViewIssue.jspa?key=XDT-737


I am trying

/**
* @hibernate.id
* name="id"
* unsaved-value="null"
* type="long"
* generator-class="native"
* @hibernate.column
* name="ID"
* sql-type="NUMBER(15,0)"
*
*/

But this is not working. It still creates as (for oracle)

<id name="id" column="id" type="long" unsaved-value="null">
<generator class="native" />
</id>

This results in a schema being created with id as NUMBER(19,0).

Where as what I want is this :


<id name="id" column="id" type="long" unsaved-value="null">
<generator class="native" />
<column name="id" sql-type="NUMBER(15,0) />
</id>

I checked the Xdoclet source and I was mistaken. I really thought this was taken care of - sorry :-).

It should not be hard to fix - edit the hibernate.xdt file. You will find about 1/3 the way down the entry for the id tag. You need to add the inclusion of the hibernate-property/xdt file. For example the lines to add will look something like:

Code:
          <XDtHibernate:setCurrentTag name="hibernate.id" mappingElement="id">
              <XDtMerge:merge file="xdoclet/modules/hibernate/resources/hibernate-column.xdt">
              </XDtMerge:merge>
          </XDtHibernate:setCurrentTag>


This will go into the following hibernate.xdt section like this (changes are towards the end):
Code:
    <XDtHibernate:ifHasPrimitiveId>
        <id
            name="<XDtMethod:propertyName/>"
            column="<XDtMethod:methodTagValue tagName="hibernate.id" paramName="column" default="<XDtMethod:propertyName/>" />"
            type="<XDtMethod:methodTagValue tagName="hibernate.id" paramName="type" default="<XDtMethod:methodType/>" />"
          <XDtMethod:ifHasMethodTag tagName="hibernate.id" paramName="length">
            length="<XDtMethod:methodTagValue tagName="hibernate.id" paramName="length" />"
          </XDtMethod:ifHasMethodTag>
          <XDtMethod:ifHasMethodTag tagName="hibernate.id" paramName="unsaved-value">
            unsaved-value="<XDtMethod:methodTagValue tagName="hibernate.id" paramName="unsaved-value" />"
          </XDtMethod:ifHasMethodTag>
        >
            <generator class="<XDtMethod:methodTagValue tagName="hibernate.id" paramName="generator-class" />">
              <XDtMethod:forAllMethodTags tagName="hibernate.generator-param" >
                <param<XDtConfig:ifConfigParamEquals paramName="version" value="2.0"> name="<XDtMethod:methodTagValue tagName="hibernate.generator-param" paramName="name" />"</XDtConfig:ifConfigParamEquals>><XDtMethod:methodTagValue tagName="hibernate.generator-param" paramName="value" /></param>
              </XDtMethod:forAllMethodTags>
              <XDtMethod:ifHasMethodTag tagName="hibernate.id" paramName="generator-parameter-1">
                <param><XDtMethod:methodTagValue tagName="hibernate.id" paramName="generator-parameter-1" /></param>
              </XDtMethod:ifHasMethodTag>
              <XDtMethod:ifHasMethodTag tagName="hibernate.id" paramName="generator-parameter-2">
                <param><XDtMethod:methodTagValue tagName="hibernate.id" paramName="generator-parameter-2" /></param>
              </XDtMethod:ifHasMethodTag>
              <XDtMethod:ifHasMethodTag tagName="hibernate.id" paramName="generator-parameter-3">
                <param><XDtMethod:methodTagValue tagName="hibernate.id" paramName="generator-parameter-3" /></param>
              </XDtMethod:ifHasMethodTag>
            </generator>
          <XDtHibernate:setCurrentTag name="hibernate.id" mappingElement="id">
              <XDtMerge:merge file="xdoclet/modules/hibernate/resources/hibernate-column.xdt">
              </XDtMerge:merge>
          </XDtHibernate:setCurrentTag>
        </id>
    </XDtHibernate:ifHasPrimitiveId>


I have not tried it. If you don't go ahead and try it out please tell me as I will follow this up and make sure that this works (or make it work) and submit to JIRA for someone to commit (I don't have commit rights for Xdoclet).

Hope this helps.

Thanks David. I will try it out. If it works, well and fine, although I would like this to incorporated in the xdoclet so that I don't have to worry about my code getting broken when the next release comes in :).

If it proves to work (or you get it to work) then post the patch (attach it) to the JIRA entry. I am sure someone will commit it to XDoclet source tree.

Sorry David...no luck :(. I tried the patch that is attached to the JIRA (pls see the link in the previous note)..but that also seems buggy., although it comes pretty much near to what is required. Just does not takes care of the other tags like many-to-one..etc. I am givin g it up for the timebeing. Will just have to hand edit the file. Will look into it when I get some free time.

Would appreciate it if you could take it up with the proper person.

Thanks

I am exactly with this problem here.
In what xdoclet version I must apply this patch ? Any 1.2.x will work ?
In the JIRA there are 2 versions of the hibernate-column.xdt and hibernate.xdt files. What is correct ? There are a comment about the 3/march version be correct but where is it ?
How I will look my tags on .java ?
