How to use multiple ejb-jar.xml files

Hello -
If the project you work on has a lot of beans that you need to configure them in one ejb-jar.xml file. Then ejb-jar.xml file will be getting bigger and bigger. I am wondering if there is any way to divide the ejb-jar.xml file into multiple sub ejb-jar.xml files and then combin them together when deploy it. Same question question for the vendor ejb-jar.xml like weblogic-ejb-jar.xml.
Thanks!
Ben

HI Ben,
No, there is no notion of combining ejb-jar.xmls at deployment time in Java EE. There is no
set limit on the number of ejb components within an ejb-jar module either.

How to write multiple ejb-jar.xml file in an ejb module

i am developing an ejb project. I hav a number of entity beans and session beans and their mapping in ejb-jar.xml. As the number of beans increases the entry of beans and mapping is also increasing. So i want to ask u that is there any mechanism so that i can divide the ejb-jar.xml file so that it will be easy to maintain it.

ejb-jar is the smallest composable unit for related EJB components. Your best bet is to create multiple ejb-jars and package them within the same enterprise application (.ear).

Stateless session Bean - xml and ejb-jar.xml file ???

Dear Experts,
Stateless-session bean
For Creating an ear file
we need ejb-jar.xml and weblogic-ejb-jar.xml files
Is these files are already available
or we have to type these files ??
Advance Thanks

My best advice: surrender to use an IDE.
You wonder sometimes at how much productivity (read as 'time') could be wasted by doing something that could be done automatically. For a learning experience or a once only exercise is fine but as a routine thing, not worth it.

No table name specified in ejb-jar.xml file

Hi, I have an entity bean defined as follows:
<enterprise-beans>
<entity>
<display-name>SponsorEJB</display-name>
<ejb-name>SponsorEJB</ejb-name>
<home>com.ultradns.j2ee.components.sponsor.ejb.SponsorHome</home>

          <res-auth>Container</res-auth>
     </resource-ref>

<cmp-field>
<primkey-field>guid</primkey-field>
     <query>
          <query-method>
               <method-name>findAll</method-name>
               <method-params></method-params>
          </query-method>
          <ejb-ql>
               <![CDATA[ SELECT OBJECT(a) FROM sponsor AS a]]>
          </ejb-ql>
     </query>
</entity>
</enterprise-beans>
In the database, I want this entity bean refers to a table named "sponsor", but I could not specify the relation in the ejb-jar.xml file. So when I deployed this bean, it auto created a table called "SponsorEJB". Where is this name come from, from display-name or ejb-name field?
Basically, how can I specify a bean "SponsorEJB" referes to a table "sponsor"?
Thanks,

First thing, to stop OC4J auto-creating tables, edit the file %J2EE_HOME%/config/application.xml. Change the first orion-application tag so that one attribute says autocreate-tables="false"
The ejb-jar.xml file describes your EJB's to the container. It is not supposed to describe which table each entity bean maps too, as this is an implementation specific property, so would not be portable between databases. Therefore you have to configure the container to point an entity to a table. Sun uses the sun-j2ee-ri.xml file to do this, and this has to be included in the deployment.
OC4J however uses the file 'orion-ejb-jar.xml', and will generate this for you. Since you have already deployed your application, this will have already been generated. Go to the directory %J2EE_HOME%/application-deployments. There will be a directory corresponding to your application name. In there is a directory corresponding to your ejb module name, and in there is the 'orion-ejb-jar.xml' file. If you open this file, you will see the entity deployment tags, an example of one is below. Edit the tag so that the table attribute points to the table in your database (note that there is a data-source attribute as well, so make sure that this points to the correct schema). The example below points the EJB Emp to the table EMP:
<entity-deployment name="Emp" max-instances="10" location="Emp" wrapper="EmpHome_EntityHomeWrapper3" table="EMP" data-source="jdbc/rob9iDS" locking-mode="optimistic" update-changed-fields-only="true" min-instances-per-pk="0" max-instances-per-pk="50" disable-wrapper-cache="true">
Hope this helps,

Query about reentrant in ejb-jar.xml file(in case of entity Bean)

Hi all friends,
I am new to EJB I couldn't understand in ejb-jar.xml file in case Entity Bean[<reentrant>False</reentrant>
&<reentrant>true</reentrant>]what is the function of this tag and what is the effect of value true and false of this tag.Can any one please explain it.
Regards
Bikash

Hi,
Re-entrant tag is used in the ejb-jar.xml to notify the container if you would want your bean to call itself through another bean.
Most of the time you would want it to be set to FALSE because you would have to consider the multi-threading issues if you set it TRUE.

How to generated weblogic-ejb-jar.xml through Jdeveloper

I am using JDevloper Studio Edition Version 11.1.1.0.2. My application works fine in OC4J 10.1.3.3.
Now, I have to deploy my application on the Weblogic 10.3 server.
My EJB already contains ejb-jar.xml, which has all the descriptions for EJB.
I want to generate weblogic-ejb-jar.xml files for my EJBs through Jdeveloper, is there any option to do that in IDE?
Regards
Edited by: chandan_kk on May 18, 2009 12:41 PM

Chandan,
Right-click the project, New...
Under the General category, choose Deployment Descriptor, then pick Weblogic Deployment Descriptor in the items. You can then choose weblogic-ejb-jar.xml in the next dialog.
If you don't see Deployment Descriptor in the category list, try selecting the All Technologies tab instead of the Project Technologies tab.

Oc4j generated finders in orion-ejb-jar.xml file causing errors

Any information or assistance would be greatly appreciated.
I have encountered a problem with the generated orion-ejb-jar.xml file.
It looks like the additional finder methods that are generated when the application
is deployed are incorrect from the 9.0.3 version to the new 10.1.2.0.2 version.
The original content of orion-ejb-jar.xml before additional finder syntax is added:
<finder-method query=
"NO_SYS_USER_OBJECT_HISTORY.USER_ID=UPPER($1) and
NO_SYS_USER_OBJECT_HISTORY.AUTOID NOT IN(
SELECT H1.AUTOID
FROM   NO_SYS_USER_OBJECT_HISTORY H1,
         (SELECT AUTOID
          FROM   NO_SYS_USER_OBJECT_HISTORY
          WHERE USER_ID=UPPER($1)
          ORDER BY DATE_TIME DESC) H2

<method-params>
   <method-param>java.lang.String</method-param>
   <method-param>java.lang.Integer</method-param>
</method-params>
</method>
</finder-method>
After deploying in 9.0.3 the following information is added to the orion-ejb-jar.xml file:
<finder-method query=
"NO_SYS_USER_OBJECT_HISTORY.USER_ID=UPPER($1) and
NO_SYS_USER_OBJECT_HISTORY.AUTOID NOT IN(
SELECT H1.AUTOID

         (SELECT AUTOID
          FROM   NO_SYS_USER_OBJECT_HISTORY
          WHERE USER_ID=$1
          ORDER BY DATE_TIME DESC) H2

</method>
</finder-method>
After deploying in 10.1.2.0.2 the following information is added to the
orion-ejb-jar.xml file:

   <method-param>java.lang.Integer</method-param>
</method-params>
</method>
</finder-method>
The problem with the 10.1.2.0.2 generated finders is that it is prepending H1 when
it should be NO_SYS_USER_OBJECT_HISTORY which results in the following error:
Exception in thread "main" com.cdtelecom.vygroe.configuration.ConfigurationException:

        at com.cdtelecom.vygroe.configuration.Configuration.getOrder(Configuration.java:239)
        at test10g.main(test10g.java:47)
I tried to manually edit the file but when I shutdown and restart oc4j it regenerates the file again.

Jingzhi -- If you define the correct EJB-QL you should get the correct SQL generated for the finder. If that's not happening can you verify it against the OC4J v903 production release and see if it is still happening. I don't know if this helps with the JDeveloper problem specifically but if you don't need to create your own finders then that I hope should help.
Thanks -- Jeff

Sun-ejb-jar.xml file is increased after deploying

When I deploy my application the size of sun-ejb-jar.xml file is increased from 140K to 6.5M!!! When I review a new file I have found that all finder methods from all beans were included into the each entity beans. Is it correct?
Thank you,

How-to use Excel for the XML file input?

Hello all,
Following our discussion with Gerhard Steinhuber on the very nice tutorial from Horst Schaude , "How to upload mass data via XML File Input" , I am starting this new discussion.
In the comments section of this previous cited tutorial, Rufat Gadirov explains how to use a generated XML from Eclipse instead of your XSD file as your source in Excel.
However, in spite of all the instructions, I am still facing the same issue in Excel when I try to save my file as XML : "The XML maps in this workbook are not exportable".
What I try to do is to create one or more Sales Orders with multiple Items in it from a XML File Input, using excel to enter data.
The part with the File input is working (if I directly upload my file to the webDAV, it creates a sales order instance with multiple items).
The only missing part is the Excel data input that I cannot make work. Any help on this matter would be greatly appreciated.
Here is my XML file that I try to use as a source in Excel before inputing data from Excel:

Hello Jacques-Antoine,
I suppose that as you have tried to construct a map from the schema, you have taken the elements from the List level down. In this case I also can't export the map.
But if you take the elements from the level MySalesOrderUploaded down, you'll get the exportable map (screenshots)

Global env-entry JNDI variables space for same ejb-jar.xml file

[Software]
jboss4.0.5
jdk 1.5
[Problem]
Is there any global <env-entry> tag for a Single EJB Module. Is there any way by which the JNDI variable can be accessed by all the modules except by binding the variables in the JNDI explixity in the code
Thanks in advance
CSJakharia

Unfortunately not. The EJB specification has always scoped the component environment
(java:comp/env) as a private environment for each EJB. The advantage is you can
assign entries within each bean easily without worrying about clashing with names selected
for other beans in the ejb-jar. That eases the process of assembling beans developed
separately into one ejb-jar since there is no possibility that their component environments
will clash.
However, the downside is just what you're pointing out, which is that in many cases
developers prefer to define a single dependency that is shared among all the
beans in the ejb module. That is the behavior of the component environment in a
web application.
We'll be looking into ways to simplify this for ejbs in a future revision of the specification.

How to use download listener for xml files?

Hi all,
In my usecase I should write the xml contents to the file using Output Stream writer.
As of now I am using the below lines of code in the download listener method.
String s = myDoc.getContent().toString();
w.write(s);
myDoc is my xml document. I can see the file but there is no content.
Kindly come out with your help in which I could achieve this.
Thanks,
Phani.

Hi john,
What all I am trying to ask is how could I write xml data to external file by clicking a button or a link etc.. which is in the JSF page.
Now for that I created a button and dragged the <af:fileDownloadActionListener> into the button.
I binded the listener with the backing bean method.
public void sayHello(FacesContext context, OutputStream out) throws IOException
OutputStreamWriter w = new OutputStreamWriter(out, "UTF-8");
IDocument myDoc = new Document2004();
myDoc.addEle("sai");
w.write(myDoc.getContent().toString());
w.flush();
in the method you can see IDocument that is an interface which I have in the external JAR files that I am using to write data to MS Word.
The myDoc which I created as an object of IDocument has lot of methods in which I am using addEle(String) which writes a string to word document.
in the writer object writer I am getting the content of the myDoc inorder to convert that to string as it will be in xml format.
When I am writing every thing I can download and save the document but unable to see the data that I have written that is "*sai*" instead a blank page is getting opened.
When I do the same with Creating a file object in the local disc using File f = new File(path) rather than downloading it using the listener I can see the contents what I have written.
This is what all I mean to ask. Kindly come up with your help
Thanks,
Phani.

How to prevent OC4J generating DD file orion-ejb-jar.xml?

I am doing a migration from JBoss to OC4J. I already have the ejb-jar.xml file which is working under JBoss. The xDoclet generate all the parts except the CMR parts so I deployed the ear file without orion-ejb-jar.xml and I got generated version from OC4J. I merge the xDoclet version with the OC4J generated version by adding the CMR parts into my xDoclet version and modify the table name and persistance fields name generated by OC4J. I don't want to mapping all the relationships so I use:
<ejb-relation >
<ejb-relation-name>AppReport-User</ejb-relation-name>
<ejb-relationship-role >
<ejb-relationship-role-name>the-User-of</ejb-relationship-role-name>
<multiplicity>Many</multiplicity>
<relationship-role-source >
<ejb-name>AppReports</ejb-name>
</relationship-role-source>
<cmr-field >
<cmr-field-name>user</cmr-field-name>
</cmr-field>
</ejb-relationship-role>
<ejb-relationship-role >
<ejb-relationship-role-name>the-appreports-of</ejb-relationship-role-name>
<multiplicity>One</multiplicity>
<relationship-role-source >
<ejb-name>Users</ejb-name>
</relationship-role-source>
</ejb-relationship-role>
</ejb-relation>
Here I just want unidirectional EJB AppReports refewrence to Users but I don't want Users EJB reference back to AppReports. The OC4j will generate DD file orion-ejb-jar.xml again with all the missing parts combined with my merged version orion-ejb-jar.xml and put it under my deploment directory. It seems it voilate the ejb-jar.xml since I don't have <cmr-field-name> defined for AppReports. My question is how I can control this way and let OC4J not generate orion-ejb-jar.xml again.

You need to have the orion-ejb-jar.xml in your app before you initially deploy it, otherwise OC4J will automatically create it for you. I would take to copy of the orion-ejb-jar.xml that is a result of the combination of OC4J and XDoclet generated and add this to my code base as the de-facto orion deployment descriptor to be included in all app deployments. On deploying the app, OC4J will see that a orion-ejb-jar file already exists and will not auto create one. Hope this makes sense!

How can I validate the ejb-jar.xml against a downloaded ejb-jar_2_1.xsd

I downloaded all configuration XML file schema,
so we can point to the schema locally. (To be able to work
even the network is not there.)
I tried to change the xmlns, xmlns:xsi and xsi:schemaLocation in the root element of ejb-jar.xml file,
I can't figure out how to make the server load the local ejb-jar_2_1.xsd file.
I'll appreciate someone can explain how the xsd file is loaded.
Thanks
Zhong

or use a tool like XMLSpy to validate your ejb-jar.xml against the XSD.
Cheers!
