XDoclet

Hello,

i have a Session Bean with a Method

USERTYPE findUser(java.lang.String name) {
  log.print(name);
}

it makes an log-output of name and name is empty String. (not NULL)

but the calling client log shows a value.....

anybody know something about this?

thanks,

Andreas Langmann

Hi Narinder.

I'm not sure what version of WS is supported. Please ask questions 
about xdoclet on xdoclet-user@.... I don't offer 
private help (unless you send me a check ;-), but I (and the other 
XDoclet developers/users) provide free help on the above-mentioned 
mailing list.

Cheers,
Aslak

Oh well, those developers who are not so far away from
frankfurt would certainly know what is it :)

And others living far away might get interested, and
choose to join us :)

As I work in Frankfurt / Darmstadt now, 
Mainz, Frankfurt, Wiesbaden, Darmstadt are all
acceptable choices. 
Heidelberg/Mannhaim could also be considered. 

But since a lot of EJB development occurs in 
Banking area, Frankfurt & around seems to be
reasonable choice.

Hi folks, 

It seems that other OS projects do "get together"
parties etc. Why not we?

It would be impossible for developers to met, since
we all are pretty distributed over the world. 

But chances are that some of the users are located
near the developers. 

So, if there are users around Frankfurt/Germany my
offer stays:
 
Let's meet somewhere after hard working day (or on
weekend). I would propose Wiesbaden ( as I'm living
there), either some nice Bar (Like "Finale", 
or "Local" ) or if the weather permits, there is
wonderfull Biergarten  near in Wiesbaden - 
"Abbelwoi Schmidt"
 
What about?
 
regards,

Hi!

At first glance, it looks like you've forgotten the @weblogic:column-
map tags. This is required in order to build the weblogic-cmp-rdbms-
jar.xml file properly (this is the file that WLS uses to figure out the 
mapping from your bean to the database).

CMR has some bugs in XDoclet 1.1.2, and many of these bugs have been 
fixed in CVS. If you still have problems after adding the 
@weblogic:column-map tags I suggest you download the CVS version of 
XDoclet and see if life gets better.

I also strongly recommend Middlegen 
(http://boss.bekk.no/boss/middlegen/), which is a sort of XDoclet 
preprocessor for EJB 2.0 Entity CMR. It will generate entity beans with 
the required (and correct) @ejb:relation and @weblogic:column-map tags 
for you. 

I consider writing deployment descriptors for CMR/CMP by hand virtually 
impossible. Writing CMR/CMP XDoclet tags makes the job easier, but it's 
still kinda hard, since there are so many possible combinations of 
directionality and cardinality. Using Middlegen makes it completely 
automatic (and therefore very easy). If Middlegen 1.0 doesn't work for 
you, try the CVS version.

Hope this helps,
Aslak

Hi,

we've just started trying out XDoclet for generation of EJB-code and have
been studying the examples included in the download. In the cmr examples
CountryBean has a unidirectional one to many relation to City. We have
managed to recreate this in our own project and would now like to create the
opposite, a unidirectional many to one relation. e.g. CityBean has a many to
one relation to CountryBean and thus contains a get and set Country + tags
for relation and CountryBean contains nothing. We can't get this to work and
hope someone can help us with it. We use weblogic and have tried several
combinations of tags, but keep getting different errors. The most common one
is:

Error while reading 'META-INF/weblogic-cmp-rdbms-jar.xml'. The error was:

In relationship ContractTypeCanHaveMultipleContracts, the
<ejb-relationship-role>,
 many contracts-belong-to-one-contracttype, defined in ejb-jar.xml must have
a
 corresponding <weblogic-relationship-role> in the RDBMS CMP deployment
descriptor
 file with the same name.
at weblogic.ejb20.ejbc.EJBCompiler.compileEJB(EJBCompiler.java:302) etc.....


Here is an example of our code:

We have a ContractBean and a ContractTypeBean where ContractType can have
many Contracts and we would like Contract to have a unidirectional relation
to ContractType.

From the ContractBean:

  /**
   * @ejb:interface-method
   *   view-type     ="local"
   *
   * @ejb:relation
   *   name             ="ContractTypeCanHaveMultipleContracts"
   *   role-name        ="many-contracts-belong-to-one-contracttype"
   *   target-role-name ="one-contracttype-has-many-contracts"
   *   target-multiple  ="yes"
   *   target-ejb       ="ContractType"
   */
  public abstract ContractTypeLocal getContractType();

  /**
   * @ejb:interface-method
   *  view-type="local"
   */
  public abstract void setContractType(ContractTypeLocal contractType);

This is one of many versions, we have also tried using weblogic:column-map
even though the documentation says they should only be used when the
foreign-key is in the other bean and we've tried using
weblogic:target-column-map even though it should be used for m:n relations.

The EjbDoclet part of our ant file:


   <!-- Run EJBDoclet -->
   <target name="ejbdoclet" depends="prepare">

      <taskdef name="ejbdoclet"
               classname="xdoclet.ejb.EjbDocletTask"
classpath="${xdoclet.jar.path};${log4j.jar.path};${ant.jar.path}"
      />

      <ejbdoclet
         sourcepath="${java.dir};${log4j.path}"
         classpathref="project.class.path"
         destdir="${generated.src.dir}"
         excludedtags="@version,@author,@date"
         ejbspec="2.0"
         force="${xdoclet.force}">

         <fileset dir="${java.dir}">
            <include name="com/tcms/data/**/*Bean.java" />
            <include name="com/tcms/facade/*Bean.java" />
         </fileset>

         <dataobject pattern="{0}DTO"/>
         <remoteinterface/>
         <localinterface/>
         <homeinterface />
         <localhomeinterface/>
         <entitypk/>
         <session/>

         <deploymentdescriptor destdir="${ejb.dd.dir}" validatexml="true" />

         <weblogic
            version="6.1"
            xmlencoding="UTF-8"
            destdir="${ejb.dd.dir}"
            validatexml="true"
            datasource="jdbc/TRIM"
         />
      </ejbdoclet>
   </target>

We hope someone can help us.

Hi all :)

Is support for JBossQL planned in XDoclet? So far it appears I can only use
specific declared (declarative) SQL queries to be generated into
jbosscmp-jdbc.xml by using the @jboss:finder-query element.

In JBoss 3 however you can now declare queries in JBossQL which is a
superset of EJB QL with added parameters for LIKE and IN and support for
ORDER BY plus dynamic queries. For example you can have a query declaration
like the following in jbosscmp-jdbc.xml :

<entity>
	<ejb-name>OrderEJB</ejb-name>
	<query>
		<query-method>
	
<method-name>ejbSelectOrderToZipCodesLike</method-name>
			<method-params>
	
<method-param>java.lang.String</method-param>
			<method-params>
		</query-method>
		<jboss-ql>
			SELECT DISTINCT OBJECT(o) FROM OrderData AS o WHERE
o.shippingAddress.zip LIKE ?1 ORDER BY o.shippingAddress.zip
		</jboss-ql>
	</query>
</entity>

It would be nice to have this in the template.

Later,
Bernie
