Publishing and Accessing OSGI Service with JBoss Fuse Fabric - osgi-bundle

I have an OSGi service that I exposed and deployed on jboss fuse fabric.
now I need to access this service from another bundle deployed on another container in jboss fuse fabric. but the service is not accessible in client container.
jboss fuse V6.3
when I deploy OSGi-service bundle and client bundle in the same container in fuse fabric, it works, but when I deploy the in different containers in does not work and show an error:
Unable to start blueprint container for bundle com.osgi.app.bean-camel-client10/1.0.0 due to unresolved dependencies [(objectClass=org.fusesource.example.service.HelloWorldSvc)]

<bean id="hello" class="org.fusesource.example.service.impl.HelloWorldSvcImpl"/>
<service ref="hello" interface="org.fusesource.example.service.HelloWorldSvc"/>
</blueprint>
How can I access the service which is deployed in another container in fuse fabric, through a camel context?

<service ref="hello" interface="org.fusesource.example.service.HelloWorldSvc"/>
means exactly this: call BundleContext.registerService("org.fusesource.example.service.HelloWorldSvc", object, properties).
After registration you have a service registered in local OSGi registry which is scoped by single instance of JVM - that never meant exposing the service to be accessible in different JVM.
If you want a service to be available in different JVM (== in different OSGi registry), you need some kind of remoting - try using CXF endpoint or one of remoting camel components (camel-cxf, camel-rest, ...).

Unable to write application logs using externalized Log4j2 XML configuration using Red Hat EAP 7.1.5

I have an application made of Spring Boot WAR packages that need to be migrated to Red Hat EAP 7.1.5.
In my current setup I do the following:
Each WAR has a dedicated log4j2 XML per environment.
This XML file name is defined in the web.xml
The folder containing the log4j2_xxxx.xml is added to the classpath in the JVM startup script.
The WARs are distributed across multiple run-time instances, with a possibility of one run-time hosting more than one WAR.
I would like to replicate the same using EAP. I do see the external log4j2 XML configuration being successfully loaded, however do not see any log statements being written at all.
I am using the following dependencies for packaging log4j2
org.springframework.boot.spring-boot-starter-log4j2 (version 1.5.7)
org.apache.logging.log4j.log4j-web (version 2.10.0)
I have tried the following:
Define a custom module under $JBOSS_HOME/modules/
Add the log4j2 XML in the same folder.
Refer this as global-module in standalone.xml
When I deploy a WAR I can see that the expected log file is created, which means the log4j2 XML configuration is being read successfully. However no logs get written at all in the application log file.
I have tried to get past this by defining a jboss-deployment-structure XML as follows:
<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
<deployment>
<exclusions>
<module name="org.apache.log4j" />
<module name="org.jboss.log4j.logmanager" />
<module name="org.jboss.logging" />
<module name="org.jboss.logging.commons.logging" />
<module name="org.jboss.logging.jul-to-slf4j-stub" />
</exclusions>
<exclude-subsystems>
<subsystem name="logging"/>
</exclude-subsystems>
</deployment>
</jboss-deployment-structure>
This results in the application logging being removed from the default JBOSS log (server.log) altogether but it does not write the logs to the designated log as well.
I would expect all the logging being done within the application to be written into the file defined by the external log4j2 XML configuration. Any idea what I am missing?

WebSphere Spring Apache CXF SOAP WebService Client timeout not working

I need to configure a SOAP WebService client with certain timeout values for connection attempts and service invocations.
The WS client is a jar dependency generated using the WSDL with Maven cxf-codegen-plugin. I use this client jar in my web app as a maven dependency and invoke the service operations.
So my webapp pom contains:
<dependency>
<groupId>my.web.service</groupId>
<artifactId>web-service-client-jar</artifactId>
<version>x.x.x</version>
</dependency>
along with the Apache CXF dependencies:
<!-- CXF dependencies -->
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-frontend-jaxws</artifactId>
<version>${cxf.version}</version>
</dependency>
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-transports-http</artifactId>
<version>${cxf.version}</version>
</dependency>
And I have defined below spring configuration to setup timeouts which does not work..
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:http-conf="http://cxf.apache.org/transports/http/configuration"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://cxf.apache.org/transports/http/configuration http://cxf.apache.org/schemas/configuration/http-conf.xsd http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd">
<http-conf:conduit name="*.http-conduit">
<http-conf:client ConnectionTimeout="20000" ReceiveTimeout="10000" />
</http-conf:conduit>
<cxf:bus>
<cxf:outInterceptors>
<ref bean="fileuploadlogOutbound" />
</cxf:outInterceptors>
</cxf:bus>
<!-- Outbound Message Logging -->
<bean id="fileuploadlogOutbound" class="test.logging.MyLoggingOutInterceptor">
<property name="prettyLogging" value="true" />
</bean>
But to my confusion, the outInterceptors defined for pretty logging works fine. Hence, I doubt if my configuration has any errors or not. FYI I'm trying to get this working in WebSphere 8.5 environment.
This is how I instantiate the WS Client in spring:
<jaxws:client id="documentUploadServiceJaxwsClient"
serviceClass="org.tempuri.IDocumentUploadService" address="#serviceEndpointString" >
<jaxws:binding>
<soap:soapBinding version="1.2" mtomEnabled="true" />
</jaxws:binding>
</jaxws:client>
Is there any steps missing in Spring config or do I need to look into WebSphere 8.5 specific configuration which will enforce HTTP/SOAP connection & response timeouts?
I figured out that my CXF configuration mentioned above works fine but the WAS environment where the application deployed is actually overriding any config you define at the application level. Hence, I followed this link to copy and define custom HTTP Transport policy where you can set values for below timeouts.
Read timeout
Write timeout
Connection timeout

Issue configuring JBoss EAP 6.1 with hibernate 3.6

I'm trying to deploy an EAR file in my local server but it seems it's still trying to use hibernate 4 (the default option, I guess).
What I have already done:
I've added a hibernate 3 module in $JBOSS_HOME$\modules\org.hibernate\3 with this module.xml file:
<module xmlns="urn:jboss:module:1.0" name="org.hibernate" slot="3">
<resources>
<resource-root path="hibernate3.jar"/>
<resource-root path="commons-collections-3.1.jar"/>
<resource-root path="jta-1.1.jar"/>
<resource-root path="javassist-3.12.0.GA.jar"/>
<resource-root path="antlr-2.7.6.jar"/>
<resource-root path="slf4j-api-1.6.1.jar"/>
<resource-root path="dom4j-1.6.1.jar"/>
<!-- Insert other Hibernate 3 jars to be used here -->
</resources>
<dependencies>
<module name="org.jboss.as.jpa.hibernate" slot="3"/>
<module name="asm.asm"/>
<module name="javax.api"/>
<module name="javax.persistence.api"/>
<module name="javax.transaction.api"/>
<module name="com.ibm.db2" />
<module name="org.infinispan"/>
</dependencies>
</module>
I've created the data source in standalone-full-ha.xml:
<datasource jndi-name="java:jboss/datasources/txdb" pool-name="txdbDS" enabled="true" use-java-context="true">
<connection-url>jdbc:db2://156.24.30.103:50000/TX_LSPDB</connection-url>
<driver>DB2Driver</driver>
<security>
<user-name> .... </user-name>
<password> .... </password>
</security>
</datasource>
My persistence.xml file has the following entry:
<persistence-unit name="esdb">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java:jboss/datasources/txdb</jta-data-source>
<class>com.gtech.commerce.UidBlockPool</class>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.DB2Dialect"/>
<property name="jboss.as.jpa.providerModule" value="org.jboss.as.jpa.hibernate:3" />
</properties>
</persistence-unit>
And this is what I get when I try to deploy:
Caused by: java.lang.ClassCastException: org.springframework.orm.hibernate3.LocalJtaDataSourceConnectionProvider incompatible with org.hibernate.service.jdbc.connections.spi.ConnectionProvider at org.hibernate.service.jdbc.connections.internal.ConnectionProviderInitiator.instantiateExplicitConnectionProvider(ConnectionProviderInitiator.java:189) [hibernate-core-4.2.0.SP1-redhat-1.jar:4.2.0.SP1-redhat-1] ... 107 more
Any idea about what I am missing?
UPDATE: I haven't found a solution, so I did the obvious workaround: I am using hibernate 3 bundled with the application, ignoring any module
Imho the problem comes from the fact that the jboss datasource built-in connection pool rely on the default persistence implementation provided with the server.
you can try to override the server datasource configuration
see https://access.redhat.com/site/documentation/en-US/JBoss_Enterprise_BRMS_Platform/5/html/BRMS_Administrator_Guide/Configuring_a_Datasource_for_JBoss_Enterprise_Application_Platform_6.html
But i don't know if you can specify the connection pool provider.
You could try otherwise to set up a custom datasource
see http://docs.jboss.org/hibernate/orm/4.1/devguide/en-US/html/ch01.html
please consider than you won't be any more in this case: JDBC connections obtained from a JNDI datasource automatically participate in the container-managed transactions of the application server.
and will have to properly configure the transaction factory.
As a more general comment I'll advise not to override provided implementation when using a Java EE application server.
If you wan't to use hibernate 3 switch to Jboss 6.0 or do not rely on the built-in java EE container features (and in this case switch to something lighter like jetty or tomcat)

Embedded ActiveMQ in Embedded Glassfish (using maven-embedded-glassfish-plugin)

Im trying to run a ActiveMQ glassfish embedded using the maven-embedded-glassfish-plugin.
I have separately completed below tutorials, so I know the basics.
The goal is to have a setup that builds in one click and avoids 3pp libraries in svn.
1 http://www.hascode.com/2011/09/java-ee-6-development-using-the-maven-embedded-glassfish-plugin/
2 http://javadude.wordpress.com/2011/07/21/glassfish-v3-1-running-embedded-activemq-for-jms-part-1/
Project setup for #2 is used as startpoint from now and I will try to merge the steps from #1
I've setup a glassfish-resources.xml hoping it will do the configuration tutorial 1 did from the glassfish admin-console.

Q1: How is glassfish-resources.xml loaded? Should i use maven admin command or place it in some META-INF?
edit: looks like it goes in web-inf if war and meta-inf if ejb-jar
Q2: Not entirely sure what is the next step. #1 has me copy activemq and log4j libraries to GLASSFISH_HOME/glassfish/lib so far I only added the dependency in the pom.xml, what is the equivalent here?
Q3: The Rar needs to be deployed as well. How can multiple applications be deployed?

Spring deployment-level configuration

When I wrote Java EE apps, I used JBoss Datasources to control which databases the deployment used. E.g. the dev versions would use a throwaway hibernate db, the ref and ops would use stable MySQL deployments. I also used MBeans to configure various other services and rules.
Now that I'm using Spring, I'd like the same functionality - deploy the same code, but with different configuration. Crucially, I'd also like Unit Tests to still run with stub services. My question is this - is there a way, in JBoss, to inject configuration with files which live outside of the WAR/EAR, and also include these files in test resources.
It is possible to add objects into the JNDI context by placing a file named xxx-service.xml into jboss's deploy directory. The app could then lookup the values via JNDI. In the example below the string "development" is added at java:/modes/deployment. To use JNDI in your unit tests use the org.springframework.mock.jndi package.
