I found it surprisingly ahrd to find aweb site to download the xsd's for SOAP 1.1 and 1.2.

Please post it here if you do know it.

I am trying to reconstruct a streamed-in SOAP message with attachmnets using SAAJ implementation in JWSDP 1.6.

After adding the attachments I make a call to the saveChanges() method of SOAPMessage. Then I stream the SOAPMessage object using the writeTo() method
after which I try to reconstruct the SOAPMessage.

But I find that the MessageFactory needs a set of MIMEHeaders and the input stream to reconstruct the SOAPMessage. But I do not have the headers in the first place since I am trying to feed the byte stream from outside a transport protocol.

Then how can I employ SAAJ as a pure SOAP manipulation tool to generate and process SOAP messages to be used outside a webservice context?

No all session beans but only some.

And I found that in the -ejb-jar.xml files these are specified as stateful whereas I had been given to understand that there were no stateful EJBs.
When I checked the stacktrace I repeatedly saw a method call
"CreateStatefulSessionContainer()". That's what prompted me to check if some were stateful.
And I did indeed find some to be stateful.
So the problem is solved.

I have the following -jboss.xml for all of my stateless session EJBs.
Trying to deploy on JBoss 4.0.1SP1 gives
Missing or invalid Instance Cache (in jboss.xml or standardjboss.xml); - nested throwable: (java.lang.ClassNotFoundException: No ClassLoaders found for: )"
error message.

But I find in the standardjboss.xml that the element has empty value:

What gives?

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE jboss PUBLIC "-//JBoss//DTD JBOSS 4.0//EN" "http://www.jboss.org/j2ee/dtd/jboss_4_0.dtd">

The link on the JBossWiki page


returns 404.

I am unable to find a page having download link for that deployer.

Could someone here post the URL please?

I am porting a JSP 1.1. app from Weblogic 5.1 to JBoss 4.0.
And I find that the JSP engine throws error complaining
"attribute <such-and-such> invalid according to TLD" for
even attributes defined in the super class of the tag.

Why is it so?

I have a JTS datasource defined in weblogic properties.
I need to move it to JBoss.
Am I supposed to use an XA datasource definition in the JBoss *-ds-.xml?

Please advise.

I keep getting the following error whenever I redeploy without restarting the server.
2005-05-17 13:21:58,022 ERROR [org.jboss.deployment.MainDeployer] Could not initialise deployment: file:/D:/jboss-4.0.1sp1/server/default/deploy/JBossDukesBank.ear
org.jboss.deployment.DeploymentException: Error in accessing application metadata: ; - nested throwable: (javax.management.InstanceAlreadyExistsException: jboss.j2ee:service=EARDeployment,url='JBossDukesBank.ear' already registered.)

What causes this?

I do not think that is a manageable solution for the situation where I have to port an app from Weblogic 5.1 toJBoss 4.0 with 95 EJBs packaged currently in as many different jars.
I would like to maintain the strcuture as much as possible.

So I need to know whether JBoss AS has any problem with multiple ejb-jars.

Is the recommended deployment policy to have a single ejb.jar?
If I am deploying multiple ejb.jar's can I have a single jboss.xml for all of them outside a particular ejb.jar?
Or is there supposed to be a jboss.xml inside each ejb.jar?

What is the point of application-client in J2EE?
I am trying to understand the jboss/DukesBank tutorial and see that the app-client.jar is also bundled within the .ear file.

If the app-client is a stand alone Java program why is it bundled with the dukesbank.ear?
And I see that the ant script's target run-client anyway uses the app-client.jar in the tutorial's jar directory which is clearly outside the JBoss app server's directory.
So why is this whole bundling within the .ear outside which this client is supposed to run?

I commented out the <module> portion declaring the app-client.jar from the application.xml of the .ear.
Then I get an error when I run the app-client complaining:

"javax.naming.NameNotFoundException: bank-client not bound
at javax.naming.InitialContext.lookup(InitialContext.java:347)
at com.sun.ebank.util.EJBGetter.getCustomerControllerHome(EJBGetter.java:69)
at com.sun.ebank.appclient.DataModel.<init>(DataModel.java:126)
at com.sun.ebank.appclient.EventHandle.<init>(EventHandle.java:51)
at com.sun.ebank.appclient.BankAdmin.main(BankAdmin.java:587)"

I am trying to understand what exactly goes on here that when trying to lookup CustomerControllerHome results in "bank-client not bound" error.

Thanks a lot

[ May 12, 2005: Message edited by: prashanth c n ]

But am I corrrect in stating that a DataSource is by default a connection pool?

I would like to know how to specify for datasources the equivalent of "capacityIncrement" found in Weblogic servers.
