[Persistence, JBoss/CMP, Hibernate, Database] - Column annotation attributes

by lightbulb432

I read the following in an EJB3 book on JBoss regarding attributes of the column annotation: "You can specify whether you want this column to be included in SQL INSERT or UPDATE by using insertable( ) and updatable( ), respectively." What does that mean? What does the insertable and updatable attributes on the Column annotation mean? It's not intuitive...you'd think that whether something is to be updated or inserted depends on the application code...what does changing these attributes actually do?

[JBossWS] - JbossWS fails when using wsdlLocation and generated WSDL

by Artur Signell

Hi, I have a simple webmethod such as the one below, taking an array as an argument. This works fine as long as I remove the "wsdlLocation" specification. | @WebService(name = "WSDLTest", targetNamespace = "namespace", wsdlLocation = "META-INF/wsdl/WSDLTest.wsdl") | @SOAPBinding(style = SOAPBinding.Style.RPC, use = SOAPBinding.Use.LITERAL) | @Stateless | public class WSDLTest { | | @WebMethod(operationName = "testMethod", action = "testMethod") | public void testMethod( | @WebParam(name = "binaryData") BinaryData[] binaryData) | throws Exception { | | System.out.println("OK"); | | } | | } | However, when I save the JBossWS-generated wsdl to a file and tell JBossWS to use it using the "wsdlLocation" parameter, I get the following error: | Caused by: org.jboss.xb.binding.JBossXBRuntimeException: Failed to resolve class name for {namespace}value: No ClassLoaders found for: java.lang.BinaryData | at org.jboss.xb.binding.sunday.unmarshalling.impl.runtime.RtElementHandler.loadClassForTerm(RtElementHandler.java:1050) | at org.jboss.xb.binding.sunday.unmarshalling.impl.runtime.RtElementHandler.classForNonArrayItem(RtElementHandler.java:1379) | at org.jboss.xb.binding.sunday.unmarshalling.impl.runtime.RtElementHandler.classForElement(RtElementHandler.java:857) | at org.jboss.xb.binding.sunday.unmarshalling.impl.runtime.RtElementHandler.startElement(RtElementHandler.java:460) | ... | BinaryData is a simple dataclass containing only an integer and methods for setting and getting it. It resides in the webservice.data-package but is for some reason searched for in the java.lang package where the Exception is defined (defining an own exception in another package changes "java.lang" to the package name where the exception is defined). JBossWS version is 1.0.3.

[EJB 3.0] - Where to place annotations?

by lightbulb432

Are annotations to be placed on getters, setters, or the fields themselves? (Do we have multiple options.) Must we remain consistent between classes? What about within classes? Is there any functional difference between putting the annotations in one place vs another?

[O'Reilly JBoss 3.0/4.0 Workbook] - Why is there a Hibernate setting in my persistence.xml?

by lightbulb432

Why in the world is there a Hibernate setting in my persistence.xml for Chapter 4? I thought this was supposed to be a EJB3 tutorial, not a Hibernate tutorial! Please explain what is going on here... Also, how does the JBoss know to use Hibernate? I haven't specified Hibernate anywhere, so how does JBoss know what to do with persistence.xml's Hibernate setting???

[Persistence, JBoss/CMP, Hibernate, Database] - Do I have to use Hibernate for EJB3 persistence?

by lightbulb432

Do I have to use Hibernate for EJB3 persistence? Or is there another alternative? What are the advantages to using Hibernate vs the alternative? I have no idea whether JBoss offers an alternative, or whether all the EJB3 persistence in JBoss is really just Hibernate. The documentation doesn't do any job of discussing this! Won't somebody clear this up finally?

[Installation, Configuration & Deployment] - ejb3.deployer?

by lightbulb432

Where is the ejb3.deployer folder supposed to be? I downloaded 4.0.4.GA of JBoss from the GUI installer (and selected the "all" install), but in my server/default/deploy there's no ejb3.deployer directory. This confuses me because the TrailBlazer documentation keeps referring to it. In fact, many other places refer to it. Where is this folder?! And where is: - ejb3-clustered-sfsbcache-service.xml - ejb3-entity-cache-service.xml Why is an "all" installation of the most recent version of the GUI install giving such a bullshit configuration, with not half of the files/folders that all the tutorials and books out there are referring to? JBoss documentation disappoints, as usual.

[JBossCache] - Re: Caching for Web services?

by zzzz8

Hi Manik, Thanks for the reply. I have an application (JEE app - running on Tomcat/EJB3 embedded/Seam) that acts as a Web services client. I use JAX-RPC's wscompile (will upgrade to JAX-WS/wsimport in the near future) to generate the client side source code. The app does tend to invoke the Web services operations fairly frequently, so it would be nice to have some sort of client side cache. I currently don't need to cluster/share state, so a local-type cache is OK for me (for now - although I may want to have some sort of replicated cache in the future). I have recently read some of the JBoss Cache documentation and I believe I may have some ideas as to how to implement this (please tell me if I'm way off or on target). Because wscompile/wsimport generate source code files that are used by the Web services client, I could possibly aspectize certain source code files generated by wscompile/wsimport. It might be a little annoying to write the jboss-aop.xml file... I have figure out which files to aspectize and how to use the pointcut language to only aspectize those source code files involved in the response messages (and any related classes used in these response classes). I would only aspectize the response message classes since there should be no need to aspectize the request message classes. I'm also assuming these source code files could be aspectized (I'm not sure if there are any limitations in aspectizing the wsimport/wscompile generated source code files)... I think once I aspectize these files (hopefully correctly), it would seem to be fairly straightforward to use the PojoCache... I probably need to learn a little bit more about PojoCache though. The toughest thing seems to be the configuration file, which really confused me. I couldn't find any definitive documentation on the XML config file (perhaps I missed it). It would be nice if there was a less intrusive way of caching Web services - perhaps via JAX-WS handlers (that might be uglier) or if JBoss Cache were better integrated with JAX-WS/JAX-RPC. Again, thanks for the assistance.

[Beginners Corner] - Re: IMG not displaying the image

by jklanka

Hi peterJ, Thanks a lot for the link and I got to know about Handling Serving External File with JBOSS 4.0.2 I placed the following code between "Hosts" Tag of server.xml file within the "/home/jboss/jboss_home/server/default/deploy/jbossweb-tomcat55.sar" path  | <Context path="/artworks" appBase="" | docBase="/home/jboss/fpartworks" | debug="99" reloadable="true"> | </Context> Then it works. I used in my JSP page as <IMG src="/artworks/xxxxx.jpg"...

[Clustering/JBoss] - Re: Need help trying to expose singleton mbean interface to

by bstansberry＠jboss.com

Sorry for a very late reply; probably won't help you but may help others. HA-JNDI provides two functions: 1) A global replicated tree. Objects bound into this tree (by a client that creates an InitialContext that connects to HA-JNDI) are replicated across the cluster and can be seen in the jmx-console's global jndi namespace on any node. 2) An ability to query the regular, non-replicated jndi tree on any node in the cluster. Thus things bound on any one node can be looked up by connecting to the HA-JNDI server running on any node in the cluster. This is actually the more important function, but it's less intuitively understood. The jmx-console doesn't show objects accessible this way in the global jndi namespace. They only appear in jmx-console in the regular jndi namespace on the server(s) where they are bound. But this doesn't mean a client doing a lookup via HA-JNDI can't find them. Your RMIAdaptor is bound in local JNDI on the singleton master node, and thus isn't visible in the global jndi namespace. But it can be looked up via HA-JNDI.
