I am working on AVOS to camunda migration project and getting issues while using existing XQuery files in JBoss AS 7. Which engine/version of XQuery, JBoss AS 7 supports?
As far as I know, JBoss EAP does not provide any XQuery processor. It however embeds Xalan which provides an XSLT processor.
RedHat would probably propose you to use their JBoss Fuse product to implement XQuery transformations. I've never used the product so I won't be able to give you any feedback on it.
Of course a viable alternative is adding an XQuery processor like Saxon to your application or platform yourself. If you want to deploy it to the platform instead of to each application, see the module mechanism.

We have been using Drools guvnor 5.5.0 on JBoss 7.0. Now we want to use drools 6.1 final version. We have deployed all the jar files but unable to access UI as could not find war file. We got war file for 5.5.0 version from http://mirrors.ibiblio.org/maven2/org/drools/guvnor-distribution-wars/5.5.0.Final/ but unable to find same for 6.1.final version. Tried to use kie-drools-wb-distribution but not working.
Can anyone tell the way to use drools 6.1 version or to get the UI to create rules?
Summarizing Goodbye Guvnor. Hello Drools Workbench.
Along with the functional and feature changes we have restructured the
Guvnor github repository to better reflect our new architecture.
Guvnor has historically been the web application for Drools. It was a
composition of editors specific to Drools, a back-end repository and a
simplistic asset management system.
Things are now different.
For Drools 6.0 the web application has been extensively re-written to
use UberFire that provides a generic Workbench environment, a Metadata
Engine, Security Framework, a VFS API and clustering support.
Guvnor has become a generic asset management framework providing
common services for generic projects and their dependencies. Drools
use of both UberFire and Guvnor has born the Drools Workbench.
Drools Workbench (drools-wb)
https://github.com/droolsjbpm/drools-wb
Drools Workbench is the end product for people looking for a web application that is composed of all Drools related editors, screens and services. It is equivalent to the old Guvnor.
You can download from http://download.jboss.org/drools/release/6.1.0.Final/kie-drools-wb-distribution-6.1.0.Final.zip

I hope this help.
I know its a very high level question, but it will be very much help full if somebody can help me to kick start the migration.
So please provide some links or use full hints to start with it.
Also if somebody knows about delta changes between JBOSS AS 6 to Wild fly.
Major change which i know that our application uses-
JBOSS AOP
JBOSS Interceptors
and binds it in jboss-aop.xml
like below
<bind pointcut="execution(public * *.DBDAO >updateBO(com.test.model.TestClass, com.test.model.TestClass2))">
<interceptor-ref name="TestInterceptor"/>
</bind>
which is not supported by wild fly now.
And so there must be other thing s which might not be supported by wild fly.
Thanks.
According documentation:
Replace JBoss AOP Interceptors
JBoss AOP (Aspect Oriented Programming) is no longer included in JBoss AS 7. In previous releases, JBoss AOP was used by the EJB container. However, in AS 7, the EJB container uses a new mechanism. If your application uses JBoss AOP, you need modify your application code as follows.
Standard EJB3 configurations that were made in the ejb3-interceptors-aop.xml file are now done in the server configuration file. For a standalone server, this is the standalone/configuration/standalone.xml file. If you are running your server in a managed domain, this is the domain/configuration/domain.xml file.
Applications that integrate AOP interceptors into the EJB layer must be redesigned to use EJB3 interceptors and CDI. Server side interceptors can be changed to EJB3 interceptors, but there is no client side interceptor in AS 7.
Like AOP exist other changes you can see in: How do I migrate my application from AS5 or AS6 to WildFly and Experiences with migrating from JBoss AS 7 to WildFly 8.1
The last link refers to some changes that are not in the official documentation.
Here is whole migration guide from Red Hat. JBoss EAP 6.2 has similar architecture to WildFly so you can use it:
https://access.redhat.com/documentation/en-US/JBoss_Enterprise_Application_Platform/6.2/html-single/Migration_Guide/index.html
I am currently developing an application which has a server part based on JavaEE 6.0 on JBoss 7.1 and a client based on Eclipse RCP 3.7.
For a simple OSGi package for a shared API I already run into trouble due to some differences in versions and depdencenies. The API requires "org.osgi.framework." for the bundle activator and "org.slf4j." for the slf4j logging API.
Currently my client is working very well, but JBoss tells me that the expected version of the OSGi import and the also the imports for slf4j do not fit...
I there a best practice to share OSGi bundles between Eclipse and JBoss? Do I need to get back to simple import and export declarations or can I used Require-Bundle somehow? Do I need to create some compatibility bundles for JBoss to get it running? What is the best way to proceed here?
UPDATE
I solved the issue by using Import-Package exclusively. For the dependency like org.osgi.framework is use version="0.0" to explain it does not matter. :-( It is not very safe, but currently I do not see another option. Is there a better way?
UPDATE 2
One also needs to pay attention to implement the correct verion of the OSGi Framework. JBoss 7.1.x only has OSGi 4.2 implemented, which has no support for typesafe service retrieval.
The best practice would be to use an import package statement with a range from the minimum version which you're using to the next major increment.
For example, if RCP expects version 1.5 of a package and JBoss expects 1.3.6, import version="[1.3.6,2)".
The Semantic Versioning whitepaper (pdf) explains why this style of import is safe and wise.
is there a reference or book, maybe a tutorial that can get me started with ejb using the technologies that I have mentioned above?
thank you
You can take a look at the JBoss Tools if you're interested in developing Java EE applications in Eclipse.
If you already know EJB (and if you don't there is quite good Enterprise JavaBeans 3.1 book) you know you can develop your EJB's as plain POJO's just with annotations. No need for fancy plugins here.
You would, however, need a plugin to easily deploy your application to the server. In this case, take a look at these JBoss Tools and this topic.
I need to automate the building and deployment of (several) BPEL applications to a weblogic server.
I now do it using jDeveloper 11g, but I guess there should be some command line tools to do it. (I come from a Microsoft /.NET / Visual Studio background, and I can automate the deployment of my .NET applications using the command line and msbuild)
Does anyone know how to do that via the command line?
I don't have any experience with BPEL on Oracle WebLogic but according to this documentation a BPEL application is packaged as a standard EAR. I don't know exactly how your sources are structured under JDeveloper but you best option here to automate the packaging and the deployment of this EAR is IMO to use Ant (or Maven but if all this is totally new for you I would recommend using Ant).
Maybe this tutorial can help you to get started for the packaging part (basically, how to use the ear task). And for the deployment, I suggest to use the wldeploy Ant task (which wraps the weblogic.Deployer utility). I've mentioned them in this recent answer.
Also have a look at this question, it seems that JDeveloper might have some support to achieve this task (but I have zero knowledge of it so I can't provide any guidance, JDeveloper is not really widely used).
I assume you are using Oracle SOA Suite 11g? If so, have a look at Oracle Fusion Middleware Developer's Guide for Oracle SOA Suite, particularly the section 38.7 Deploying SOA Composite Applications and the subsection 38.7.5 Managing SOA Composite Applications with Scripts.
You may also find useful advice in the Oracle BPEL forums.
