Parsing ejb-jar.xml using jaxb

hi all,
how to parse the ejb-jar.xml using jaxb? can anybody send the information about the API which we have to use to parse the ejb-jar.xml? (ejb2.0)
i need the details about all ejbs in an application, (like jndi name, Home and Remote name). so, how can i parse the ejb descriptors?
regards,
panneer

Hi Panneer,
Well, parsing the EJB descriptors is, in principle, a task for the EJB container where they are deployed. From what you wrote I assume that you need to gather that kind of info to visualize in some (monitoring?) tool. Is that correct?
If so, the question would be whether you have access to the EJB jar on the file system (before it's deployed) or you can only connect to the server with the already deployed EJBs. In the latter case, this information is shown in the [NWA plugins|http://help.sap.com/saphelp_nwce10/helpdata/en/0b/5b5a42ea221153e10000000a155106/frameset.htm]. There are also some [telnet commands|http://help.sap.com/saphelp_nw04/helpdata/en/79/3cf82ade038d45a21fbfdaee349b22/frameset.htm] in NW 04 and 7.0 (04s).
If you have access to the EJB jar file, you can parse the descriptors using DOM or SAX, but I'm not aware of any pre-defined JAXB API for this purpose. Probably you can also generate the mapped classes yourself and use them, however I'm not sure how that works with DTD (because of EJB 2.0).
HTH!

SAXException while parsing 'ejb-jar.xml'.

Hi
My machine is behind a proxy. When I try to compile an EJB using ANT 1.3 I am getting the following Exception.

Please help me

It's http://java.sun.com/j2ee/dtds/ejb-jar_1_1.dtd. Also, check your doctype -
it publicid is correct (-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 1.1//EN),
local DTD will be used.

Can't create a JAXB binding for ejb-jar.xml using xjc

Hi all,
I have been trying to build a JAXB binding for EJB deployment descriptors, mainly because I have to update a hand-cranked ejb-jar.xml file on the fly with some additions that have come from a code generator.
I have tried to use
xjc ejb-jar_2_1.xsd j2ee_1_4.xsd ejb-jar_2_1.xsd
xjc on the schema definitions I found at http://java.sun.com/xml/ns/j2ee/ but I can't get it to work. It produces reams of errors, see below for a short extract.
Of course, someone could put me out of my misery and tell me where to find a binding that someone else has done. I can't be the first chimp on the planet that has wanted to do this!
Any help much appreciated.

WL ejbc error on a healthy ejb-jar.xml

Hi,
I have an EJB with one-to-one mapping to a few other EJBs.
I had this completely functional in WL 6.0 with sp1.
However when I try to deploy the same EJB in WL 6.1, it says
ERROR: Error parsing 'ejb-jar;xml' line 62: Element type
"ejb-entity-ref" must be declared.
Wired part is that the ejb-jar.xml on line 62 has the
ejb-entity-ref tag defined.
So, who is nuts here ??
thanks
Sanjeev Hegde

WLS 6.1 implements EJB 2.0PFD2 (including some of the latest changes in
the EJB 2.0 spec).
You will need to upgrade your EJBs to support the latest EJB 2.0
changes.
If you have further questions about our EJB 2.0 support, I would suggest
that you post them in the EJB beta newsgroup.

I used Korean language in comment.
But the charset of XML was iso-8859-1.

I am running Weblogic 8.1 SP3 on Windows XP Pro.
The XML is valid for the specified DTD according to my XML editor.
The relevevant fragment from weblogic-ejb-jar.xml is included below.
Any help much appreciated.
Gavin.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE weblogic-ejb-jar PUBLIC "-//BEA Systems, Inc.//DTD WebLogic 8.1.0 EJB//EN" "http://www.bea.com/servers/wls810/dtd/weblogic-ejb-jar.dtd">

</security-role-assignment>
<security-role-assignment>
<role-name>MarsViewer</role-name>
<externally-defined/>
</security-role-assignment>
</weblogic-ejb-jar>

I tried using the <global-role/> tag instead - this does deploy without any errors - but when I call the secure EJB method I get the Security Violation error below.
The DTD says using the <global-role/> tag is fine, albeit deprecated, but the Weblogic 8.1 manual says this has been replaced by <externally-defined/>, so I'm not sure if this should work or not.
[EJB:010160]Security Violation: User: 'ghughes' has insufficient permission to access EJB: type=<ejb>, application=_appsdir_mars-marketdata_ear, module=ejb-marketdata.jar, ejb=marketdata.MarketDataManager, method=getEnergyOverview, methodInterface=Remote, signature={java.util.Date}.
So on the whole I'd prefer to work out why Weblogic isn't recognising <externally-defined/> - I've included the full deployment descriptor below - I'm generating it using the latest snapshot of XDoclet - is the DTD specified correct for Weblogic 8.1 SP3 ? (It matches the one specified in http://e-docs.bea.com/wls/docs81/ejb/DDreference-ejb-jar.html - but I can't think of anything else that could be wrong).
Any tips much appreciated as I need to enable an administrator to customise these roles at runtime rather than hard-coding the role - group mappings into the deployment descriptors.
Thanks,
Gavin.

Using JMX to read ejb manifest jar and ejb-jar.xml in ejb jar inside ear

Hello,
I have an ear deployed on weblogic console. I need to check contents of manifest file and ejb-jar.xml of a jar that is present in the deployed ear.
Currently I am using below code to access jar inside ear deployed :
Hashtable env = new Hashtable(5);
env.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
env.put(Context.PROVIDER_URL,
url);
env.put(Context.SECURITY_PRINCIPAL, user);
env.put(Context.SECURITY_CREDENTIALS, password);
Context ctx = new InitialContext(env);
mBeanHome = (MBeanHome)ctx.lookup(MBeanHome.ADMIN_JNDI_NAME);
String type = "EJBComponentRuntime";
Set beans = mBeanHome.getMBeansByType(type);
try{
for(Iterator it=beans.iterator();it.hasNext();)
EJBComponentRuntimeMBean rt = (EJBComponentRuntimeMBean)it.next();
if(rt.getParent().getName().equals("xxx")){
System.out.println(rt.getName());
l.add(rt.getName());
Here xxx is the ear. Now I need to get inside the jar (represented) by variable rt and access its manifest file,ejb-jar.xml
Does anyone have an idea how to do this?
regards
Sameer

Isn't it possible to put them there manually? :)

How ejb-jar.xml is Used by ejb Container

Can anyone please explain me about how ejb-jar.xml is Used by ejb Container when a request is sent by a client(ie StandAlone program or a WebService)
Thanks in Advance

Ejb-jar.xml parse excpetion...

Could someone please take a look at my ejb-jar.xml code and try to see the error in it?
I am trying to load this jar into WebLogic 6.1 and when i try and deploy the bean i get the following exception:
Unable to deploy EJB: RequestBean.jar from RequestBean.jar:
The XML parser encountered an error in your deployment descriptor. Please ensure that your deployment descriptor corresponds to the format in the DTD. The error was:
org.xml.sax.SAXParseException: The content of element type "ejb-jar" must match "(description?,display-name?,small-icon?,large-icon?,enterprise-beans,relationships?,assembly-descriptor?,ejb-client-jar?)".
Here is the xml behind my ejb-jar.xml file:
<!DOCTYPE ejb-jar PUBLIC '-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN' 'http://java.sun.com/dtd/ejb-jar_2_0.dtd'>

</ejb-jar>Thanks for your time,
Nate

I also get the following exception right below the exception posted in the first post:
org.xml.sax.SAXParseException: The content of element type "ejb-jar" must match "(description?,display-name?,small-icon?,large-icon?,enterprise-beans,relationships?,assembly-descriptor?,ejb-client-jar?)".]
File: ejb-jar.xml Line: 14 Column: 21
The nice thing about this exception is it shows the row and column. However, I can't figure out where this is in the ejb-jar.xml file? Does the parser smoosh everthing together and count from there? Or does the parser count from my formatting?
Thanks again for your time,
Nathan

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.

Weblogic 10.3.0 Deployment error when using ejb-jar.xml

Hi,
I am getting the following error while deploying my EJB3 application on Weblogic 10.3.0. This is happening only if I include ejb-jar.xml.
As per the EJB3 descriptor spec, Remote Home or Local home are not exists.
Is this a issue in Weblogic 10.3.0 or am I missing any special setup ?
Please help.

Ejb-jar.xml not using fully qualified class names

HI,
I am trying yo upgrade my application from weblogic 8.1 to weblogic 9.2.3. My application has both session and enitybeans. I updated weblogic related jars with 9.x version. But while running ejbgen, i am getting the following exception.
*[java] weblogic.ejb.container.deployer.DeploymentDescriptorException: Unable to set the transaction attribute for method 'updateService(abcTO)' on EJB 'AbcService'. No matching method could be found. Please verify the method signature specified in the ejb-jar.xml file matches that of your Local interface for this EJB.*
In ejb-jar.xml file, it is not creating the fully qualified class name for abcTo in <method-param>. In component interface, the method signature is not contaning fully qualified class name for the parameters and return values.
If i change the signature in the bean with the fully qualified class name of the parameter, the ejb-jar.xml file is creating fine. But there are 100's of signatures i need to change if this is the only solution.
Can you please advice what i need to change when i upgrade from weblogic 8 to 9 series from session and entity bean's point of view?
Thanks in Advance
Naveen.

ejb-jar.xml has always required fully-qualified class names. If some vendors have accepted unqualified class names unfortunately that
behavior is non-portable. Your best bet is to fully-qualify the names. Perhaps you can find some tools to help you given the large
number of components in your application.
