I am getting an exception as given below.
I want Response class to be loaded from jawax-ws-rs.api.jar.
but its getting loaded from the j2ee.jar and throwing the below error:-
java.lang.NoSuchMethodError: javax/ws/rs/core/Response.readEntity(Ljava/lang/Class;)Ljava/lang/Object
Is there any way we can skip loading of j2ee.jar at startup of WebSphere?
Your question is incorrect, probably what you really want is to replace JAX-RS engine provided with WAS with some third part. And you should never pack j2ee.jar with your application as all required classes are already loaded by the server.

I am using WELD 2.4.1.Final for my web application running on Tomcat 7. I am having JSF and Jax-RS Rest services in my web application. I have implemented asynchronous JAX-RS Rest Services. Async Rest call works perfect, but in logs I got following Warnings :
WELD-000715: HttpContextLifecycle guard not set. The Servlet container is not fully compliant.
WELD-000714: HttpContextLifecycle guard leak detected. The Servlet container is not fully compliant. The value was 1
WELD-000335: Conversation context is already active, most likely it was not cleaned up properly during previous request processing
I got from this website : http://weld.cdi-spec.org/documentation/, that these are issues from Tomcat.
Should I consider them or just ignore? If I ignore, does it affect performance of my web app? Is there any Workaround to get rid of this warnings?
I'm trying to use Swagger (1.5.12) Annotations in my web application deployed to WAS Liberty Profile 16.0.0.3.
However, when I access the /swagger.json URL, the following exception is thrown:
[err] [Default Executor-thread-13] WARN org.reflections.Reflections - could not create Vfs.Dir from url. ignoring the exception and continuing
[err] org.reflections.ReflectionsException: could not create Vfs.Dir from url, no matching UrlType was found [wsjar:file:/opt/ibm/WebSphere/Liberty-ND-16.0.0.3/wlp/usr/servers/defaultServer/workarea/org.eclipse.osgi/61/data/cache/com.ibm.ws.app.manager_87/.cache/!/WEB-INF/classes/]
either use fromURL(final URL url, final List urlTypes) or use the static setDefaultURLTypes(final List urlTypes) or addDefaultURLTypes(UrlType urlType) with your specialized UrlType.
[err] at org.reflections.vfs.Vfs.fromURL(Vfs.java:109)
Do you know how to overcome this issue?
I'd like to use this swagger.json output with the REST API Documentation that comes with WLP under /ibm/api/explorer/ context.
Thanks, any suggestions are really welcome!
I solved the problem adding the following setting in server.xml:
<classloading useJarUrls="true"/>
I also had to downgrade to Swagger 1.5.3
Yes, at the moment WebSphere Liberty supports Swagger annotations 1.5.3. You won't get a compiler error if using 1.5.4, but full support for that version is not there yet.
The version of the annotations package in Open Source moves up quickly, but rest assured that in the next few months WebSphere Liberty will synchronize with the latest versions.
I'm using neo4j in a glassfish server through a modified version of Alex Smirnov neo4j JCA connector.
My version is available here : https://github.com/Riduidel/neo4j-connector
I'm using this connector with neo4j 1.8.
As a consequence, when i want to use it, i first install the connector in my Glassfish application server, then use this connector in applications wishing to connect to.
It works OK when using it with fresh stores.
But, when using it with stores created with previous version, I encounter weird bugs.
Typically, I got today the following stack
javax.resource.spi.ResourceAllocationException: Error in allocating a connection. Cause: Failed to transition org.neo4j.kernel.InternalAbstractGraphDatabase$DefaultKernelExtensionLoader#3bbd53b1 from NONE to STOPPED

A fast inspection reveals that this exception is linked to an undeletable "write.lock" file. My write.lock file can't be deleted because I guess migration is not over.
How can I make sure the migration is done before using it without migrating it outside of Glassfish ?
Is there a way to ahve exclusive store migrations in that context ? And if so, how ?
And is it the solution for my problem ?
EDIT 1 Added exception message.
EDIT 2 All this only happen when loaded graph was previously used with a Neo4j 1.5 and now with a Neo4j 1.8 connector. when graph is created by connector, absolutely no error happens.
EDIT 3 Strangely enough, this happens as long as there is no debugger plugged into that code : as soon as I try to debug it, the issue stop appearing. Which make me thinking there may be a migration cleanup mechanism that remvoe the write lock once migration is done, and this cleanup is not performed when using my neo4j JCA connector. Is it a valid observation ?
I am not too familiar with the JCA connector, but to be sure, I would just write a very small migration java class that opens the database, lets it migrate and shut down. Then try it again with the JCA connector?
After further investigations, truth revealed to not be in multiple calls to the EmbeddedGraphDatabase constructor, but instead to multiple identicail IndexProvider being loaded.
I use neo4j embedded in an open-source JCA connector.
In this connector, the org.neo4j.kernel.Service class is replaced by a custom one which contains a workaround regarding service loading for JBoss non shared libraries.
Unfortunatly, in our context, this workaround implies loading twice the index provider :
once using the EAR classloader
once using the Glassfish library classloader.
Why ?
Because, as our neo4j instance is using for application data AND for authentication, neo4j connector jar is put in ${domain}/lib. As a consequence, due to Classloader delegation in application server, the EAR classloader delegates to the Glassfish library classloader, and find this way the LuceneIndexProvider. Then, the Glassfish library classloader is directly used to load the same LuceneIndexProvider class.
This concludes by us having two LuceneIndexProvider objects, both trying to migrate the lucene index. Which lead to the AssertionError as the write.lock file created by the first object should be deleted by the second one, which can't do that.
I've then changed slightly that very specific class to use JBoss workaround only when default loading mechanism do not return any class (seee commit here). This small change worked like a charm, so I think you can considered this issue as fixed.
I am using eclipse (Juno) to develop a web service for Tomcat 7 and Axis2. I have a java bean which I want to use to create the web service. The web service wizard seems to run ok but when the server starts I get this error message:
2012-11-08 13:31:20,059 ERROR [localhost-startStop-1] configuration.EngineConfigurationFactoryServlet (EngineConfigurationFactoryServlet.java:162) getServerEngineConfig
- Unable to find config file.
Creating new servlet engine config file: /WEB-INF/server-config.wsdd
I understand this to mean that server-config.wsdd is missing. How do I create this file? Why isn't it being generated automatically by the wizard?
Update
I recreated the project and the error message does not appear. I guess that I did something wrong. Perhaps Axis1 was being used as Andreas Veithen suggests below.
That is an error message generated by Axis 1.x. If you are developing an Axis2 service, then you shouldn't attempt to deploy it on Axis 1.x.
While generating java beans or wsdl, select start service option in webservices wizard then eclipse will create the server-confid.wsdd file for you. Hope this helps.
I am using an embedded version of jetty 7 to load a web application using Apache MyFaces 1.2 in a junit 4 test class on the advice from another thread.
While running the test i get this error.
java.lang.IllegalStateException: No Factories configured for this Application. This happens if the faces-initialization does not work at all - make sure that you properly include all configuration settings necessary for a basic faces application and that all the necessary libs are included. Also check the logging output of your web application and your container for any exceptions!
If you did that and find nothing, the mistake might be due to the fact that you use some special web-containers which do not support registering context-listeners via TLD files and a context listener is not setup in your web.xml.
A typical config looks like this;
<listener>
<listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>
This application works fine with tomcat, weblogic and even oc4j!
How can i get this to work with jetty?
I solved this by adding the myfaces-impl jar which had the .tld file inside the WEB-INF/lib directory.
