Re: [Xdoclet-user] @weblogic.transaction-isolation TRANSACTION_READ_COMMITTED generate empty setting.

[[EMAIL PROTECTED]]

What does your <weblogic> element under build.xml look
like?

There is an error in the template file for
weblogic-ejb-jar.xml for XDoclet 1.2.3.  I have
attached a version of it with the correction necessary
to generate the <isolation-level> output at the method
level.

Here is what I used in my build.xml with your example
and it worked fine.

<target name="ejbdoclet" ...blah, blah, blah...>

     <ejbdoclet>

...blah, blah, blah...

     <weblogic destDir="${src.ejb-meta-inf.dir}"
               mergeDir="${xdoclet.merge.dir}"
              
templateFile="${weblogic.template.file}"
               validateXML="true"
               version="8.1"
               createtables="Disabled"
               xmlencoding="UTF-8"
     />

</ejbdoclet>            

It did not matter if I put the

@weblogic.transaction-isolation
TRANSACTION_READ_COMMITTED

tag at the class or method level or both.  In all
three cases, my <isolation-level> element was not
empty, but contained TRANSACTION_READ_COMMITTED as
expected.

CLASS LEVEL OUTPUT:

   <transaction-isolation>
     
<isolation-level>TRANSACTION_READ_COMMITTED</isolation-level>
      <method>
         <description><![CDATA[Transaction isolation
for SSBFacade]]></description>
         <ejb-name>SSBFacade</ejb-name>
         <method-name>*</method-name>
      </method>
   </transaction-isolation>


BOTH CLASS AND METHOD LEVEL OUTPUT:

   <transaction-isolation>
     
<isolation-level>TRANSACTION_READ_COMMITTED</isolation-level>
      <method>
         <description><![CDATA[Transaction isolation
for SSBFacade]]></description>
         <ejb-name>SSBFacade</ejb-name>
         <method-name>*</method-name>
      </method>
   </transaction-isolation>
   <transaction-isolation>

     
<isolation-level>TRANSACTION_READ_COMMITTED</isolation-level>

      <method>
         <description><![CDATA[]]></description>
         <ejb-name>SSBFacade</ejb-name>
         <method-intf>Remote</method-intf>
         <method-name>loadAll</method-name>
         <method-params>
         </method-params>
      </method>
   </transaction-isolation>


METHOD LEVEL OUTPUT:

   <transaction-isolation>

     
<isolation-level>TRANSACTION_READ_COMMITTED</isolation-level>

      <method>
         <description><![CDATA[]]></description>
         <ejb-name>SSBFacade</ejb-name>
         <method-intf>Remote</method-intf>
         <method-name>loadAll</method-name>
         <method-params>
         </method-params>
      </method>
   </transaction-isolation>


Thanks.
