    What Xdoclet tag can I use for read-ahead/left-join?

    ingo Newbie

      Hi all,
      I want to use the left-join read-ahead strategy.

      A example from jbosscmp-jdbc.xml:

      <read-ahead>
      on-find
      <page-size>4</page-size>
      <eager-load-group>basic</eager-load-group>
      <left-join cmr-field="bs" eager-load-group="basic"/>
      <left-join cmr-field="cs" eager-load-group="basic"/>
      </read-ahead>

      The problem is that I'm using Xdoclet to build my configuration files and I can't find a tag for this.

      Does it exist a tag for this?
      If not, does it exists another easy way to achieve this?

      Any ideas?

          You must use a merge file. All possible merge-files you find here:

          http://xdoclet.sourceforge.net/xdoclet/ant/xdoclet/modules/jboss/ejb/JBossSubTask.html

          the very tricky thing is, that you must build the package-structure and store the file in the right package. Here is my structure:

          Source-code:
          src/main/java/ch/imis/ishop/ejbbackend/article/ejb

          The merge-directory:
          src/xdoclet

          now you must build inside the merge-dir the package-structure like this:
          src/xdoclet/ch/imis/ishop/ejbbackend/article/ejb

          and store the merge-file there.

          In the ant-task you must specify the merge-dir:
          <ant:ejbdoclet
          addedTags=""
          excludedTags=""
          destDir=""
          verbose=""
          mergedir="/src/xdoclet">

          my merge-file-name:
          jbosscmp-jdbc-Article.xml
          Article stands for the ejb-class-name

          Another hint:
          A merge-file defines a part of the whole target-xml-file, so you must specify the whole part and can't specify only the things you need additional to the specified tags inside the class-file. Will also mean the xdoclet-tags inside the class will not be considered for the part of the merge-file
