Running Arquillian in Equinox - osgi

I'm trying to run integration tests in an OSGi container, namely the Equinox container embedded in Eclipse, using Arquillian in remote mode.
I followed the instructions given on the JBoss OSGI site. So I began by provisionning my target platform by adding these artefacts (which I found by browsing the jboss repository) :
<dependency>
<groupId>org.jboss.arquillian.osgi</groupId>
<artifactId>arquillian-osgi-bundle</artifactId>
<version>1.0.0</version>
</dependency>
<dependency>
<!-- required by arquillian-osgi-bundle -->
<groupId>org.jboss.logging</groupId>
<artifactId>jboss-logging</artifactId>
<version>3.1.0.GA</version>
</dependency>
<dependency>
<groupId>org.jboss.osgi.jmx</groupId>
<artifactId>jboss-osgi-jmx</artifactId>
<version>1.0.10</version>
</dependency>
When I try to validate the bundles, I get unsatisfied imports from jboss-osgi-jmx :
missing package org.jboss.osgi.spi.capability
missing package org.jboss.osgi.testing
Apparently, the missing packages belong to these artifacts (once again, found by browsing):
<!-- osgi.spi : this one ?-->
<dependency>
<groupId>org.jboss.osgi</groupId>
<artifactId>jboss-osgi-spi</artifactId>
<version>1.0.10</version>
</dependency>
<!-- or that one ?-->
<dependency>
<groupId>org.jboss.osgi.spi</groupId>
<artifactId>jbosgi-spi</artifactId>
<version>1.0.26</version>
</dependency>
<!-- osgi.testing -->
<dependency>
<groupId>org.jboss.osgi.testing</groupId>
<artifactId>jbosgi-testing</artifactId>
<version>1.0.4</version>
</dependency>
But neither of these artifacts is an OSGI bundle, so I'm stuck with unresolved constraints.
So, my questions are :
did I screw up my platform configuration ?
does anybody already succeeded at using Arquillian inside a non-JBoss
osgi container in remote mode (plain felix would be OK) ?

Try Pax Exam for OSGi testing. You can choose between embedded and remote usage (Native Test Container vs. Forked Test Container).
Pax Exam supports all OSGI 4.2 compliant frameworks. It it regression tested on Equinox, Felix and Knopflerfish.

Spring Boot uses Elasticsearch 6.4 by default. By using 6.6.2 as the versions for two Elasticsearch modules you will have ended up with a mixture of the two versions. You should remove the <version> configuration in your pom. If you are able to use Spring Boot’s default version there’s nothing more to do. If you need to use 6.6.2 you should add an entry in your pom’s <properties>:
<elasticsearch.version>6.6.2</elasticsearch.version>

Spring boot failing to start with Spring Cloud AWS Core dependency

I am writing a spring boot app that accesses stuff from an s3 bucket, but I get a NoClassDefFoundError when I use the starter spring-cloud-starter-aws dependency from the spring initializer.
Am I missing some other dependency here?
Below are my dependencies.

I also defined the dependencyManagement block for spring-cloud-dependencies and use Edgware.SR1 as my spring-cloud-version.
My app fails with the following error when starting up.

Not sure what am I missing here? Please let me know if you need any more details with this. The version of spring boot I am using is 1.5.9.RELEASE
The correct dependency is the spring-cloud-aws-context. Add the following in your pom file (version 1.2.2 as of Nov 22, 2017):
<!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-aws-context -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-aws-context</artifactId>
<version>1.2.2.RELEASE</version>
</dependency>
Below are the Spring Cloud AWS modules:
Spring Cloud AWS Core is the core module of Spring Cloud AWS providing basic services for security and configuration setup. Developers will not use this module directly but rather through other modules. The core module provides support for cloud based environment configurations providing direct access to the instance based EC2 metadata and the overall application stack specific CloudFormation metadata.
Spring Cloud AWS Context delivers access to the Simple Storage Service via the Spring resource loader abstraction. Moreover developers can send e-mails using the Simple E-Mail Service and the Spring mail abstraction. Further the developers can introduce declarative caching using the Spring caching support and the ElastiCache caching service.
Spring Cloud AWS JDBC provides automatic datasource lookup and configuration for the Relational Database Service which can be used with JDBC or any other support data access technology by Spring.
Spring Cloud AWS Messaging enables developers to receive and send messages with the Simple Queueing Service for point-to-point communication. Publish-subscribe messaging is supported with the integration of the Simple Notification Service.
Ref: http://cloud.spring.io/spring-cloud-aws/spring-cloud-aws.html#_using_amazon_web_services
It seems com.amazonaws.AmazonClientException is not found in the classpath. I think you can add the following dependency in your POM.xml file to solve this issue.
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-aws-core</artifactId>
<version>1.2.2.RELEASE</version>
</dependency>
You need to include dependency mentioned by #alltej. Also you need to add below property in application.properties file if you are running on local.
cloud.aws.stack.auto=false

Servlet 500 error ClassNotFound exception

I'm building a web app using Vaadin and it needs to communicate with several REST APIs. I've set it up in IntelliJ with Maven. I was thinking for the REST client I would use GSON to parse the JSON objects I'd be receiving from the open APIs, however, the application crashes due to a servlet exception error.
Caused by:
java.lang.ClassNotFoundException: com.google.gwt.json.client.JSONObject
I've added the GSON dependency to the pom.xml:
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.3.1</version>
</dependency>
And have tried changing the module settings from Provided to Compiled to Runtime but with no change.
I'm just stumped as to why the GSON jar appears in the project dependencies within IntelliJ using Maven but fails on run time. I've seen references to Eclipse and including the jar in the classpath but, again, I'm using IntelliJ/Maven to build my Vaadin project and satisfy dependencies.
Any help is greatly appreciated!
Add below dependency in your classpath:
<dependency>
<groupId>com.google.gwt</groupId>
<artifactId>gwt-user</artifactId>
<version>2.3.0</version>
</dependency>

Glassfish incremental deployment failes when including Selenium

I have a Java EE project which is meant to run on Glassfish 4.1. I want to use Selenium to collect information from some web pages, i.e. I need to include Selenium in the deployment (not just for tests).
I am using Eclipse IDE and have previously utilized the incremental deployment function in Eclipse to automatically deploy all saved changes to the project. But when I included (with Maven) the dependencies for Selenium incremental deployment stopped working. The project can still be deployed to Glassfish but I have to restart Glassfish between every change. I get the following error in Eclipse:
Exception while loading the app : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: java.lang.RuntimeException: com.sun.faces.config.ConfigurationException: java.util.concurrent.ExecutionException: com.sun.faces.config.ConfigurationException: Unable to parse document 'bundle://136.0:1/com/sun/faces/jsf-ri-runtime.xml': DTD factory class org.apache.xerces.impl.dv.dtd.DTDDVFactoryImpl does not extend from DTDDVFactory.. Please see server.log for more details.
org.apache.xerces.impl.dv.dtd.DTDDVFactoryImpl is included with Selenium as a transitive dependency (xerces:xercesImpl:2.11.0).
Here are my Maven dependencies:
<dependency>
<groupId>org.jboss.arquillian.selenium</groupId>
<artifactId>selenium-bom</artifactId>
<version>2.44.0</version>
<type>pom</type>
<scope>import</scope>
</dependency>
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-htmlunit-driver</artifactId>
</dependency>
I hope there is a solution to this but after reading Jens Schauder's response in Dealing with "Xerces hell" in Java/Maven? I'm afraid there might not be. Anyone?
I currently can't reproduce the issue with a simple project, did you make sure that you don't have any other dependencies which are importing another version of xercesImpl?
You can try to place the xercesImpl-2.11.0.jar and the transitive dependency xml-apis-1.4.01.jar in the lib folder of your Glassfish domain and exclude it from your dependencies like this:
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-htmlunit-driver</artifactId>
<version>2.44.0</version>
<exclusions>
<exclusion>
<artifactId>xercesImpl</artifactId>
<groupId>xerces</groupId>
</exclusion>
</exclusions>
</dependency>

jetty-maven-plugin and loadTimeWeaver

can't seem to have my spring webapp working with jetty-maven pluging
i always get
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loadTimeWeaver': Initialization of bean failed; nested exception is java.lang.IllegalStateException: ClassLoader [org.eclipse.jetty.webapp.WebAppClassLoader] does NOT provide an 'addTransformer(ClassFileTransformer)' method. Specify a custom LoadTimeWeaver or start your Java virtual machine with Spring's agent: -javaagent:org.springframework.instrument.jar
though i have:
set MAVEN_OPTS to javaagent:/Users/blabla/.m2/repository/org/springframework/spring-instrument/3.1.3.RELEASE/spring-instrument-3.1.3.RELEASE.jar
set JAVA_OPTIONS to the same thing
added dep to spring-instrument and spring-aspects
added jvmArgs with -javaagent:.... to jetty-maven-plugin configuration
Probably you are missing few jars aspectjweaver aspectjrt spring-instrument
Additionally you may want to try explicitly defining the bean loadTimeWeaver in applicationcontext.xml file.
<property name="loadTimeWeaver">
<bean id="instrumentationLoadTimeWeaver" class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"/>
</property>
When launching Jetty from Maven (using mvn jetty:run), Jetty will run in the same JVM as maven does, so you'll need to pass any options using MAVEN_OPTS.
(Be sure to include the minus sign before javaagent, as I didn't see that in your snippet).
export MAVEN_OPTS=-javaagent:org.springframework.instrument-3.0.5.RELEASE.jar
A complete example of load time weaving in jetty using Maven can be found on Github.
https://github.com/zzantozz/testbed/tree/master/spring-aspectj-load-time-weaving-in-jetty
Without more details about your pom.xml file... it's not easy. But one common issue with jetty plugin are the dependencies.
One rule that always worked for me is to put all dependencies of your war with scope provided as direct dependencies of the maven-jetty-plugin.
I suggest you to put spring-instrument and spring-aspects as direct dependencies of the maven-jetty-plugin too.
According my understanding:
set MAVEN_OPTS to javaagent:/Users/blabla/.m2/repository/org/springframework/spring-instrument/3.1.3.RELEASE/spring-instrument-3.1.3.RELEASE.jar
is the correct way to pass jvm args to the jetty JVM (since jetty run in the same JVM as maven)
I've had same issue I use load time weaving in spring. How can i set class loader in jetty?. I've resolved it by adding a "-Xbootclasspath/a:[path to jar]" as JvmArgs param.
Now it's looks like
<extraJvmArgs>-Xmx4g -XX:MaxPermSize=512m -javaagent:C:\Users\auldanov\.m2\repository\org\springframework\spring-instrument\3.1.4.RELEASE\spring-instrument-3.1.4.RELEASE.jar -Xbootclasspath/a:C:\Users\auldanov\.m2\repository\org\springframework\spring-instrument\3.1.4.RELEASE\spring-instrument-3.1.4.RELEASE.jar</extraJvmArgs>
I finally made it work following the example from ddewaele. So apart from doing
set MAVEN_OPTS to
javaagent:/Users/blabla/.m2/repository/org/springframework/spring-instrument/3.1.3.RELEASE/spring-instrument-3.1.3.RELEASE.jar
You have to check the dependencies you have added. I was missing spring-tx. You need to have these dependencies:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>3.0.5.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aspects</artifactId>
<version>3.0.5.RELEASE</version>
</dependency>
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjweaver</artifactId>
<version>1.6.10</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>3.0.5.RELEASE</version>
</dependency>
<!-- Following dependencies are required because of spring-aspects -->
<dependency>
<groupId>org.hibernate.javax.persistence</groupId>
<artifactId>hibernate-jpa-2.0-api</artifactId>
<version>1.0.0.Final</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-tx</artifactId>
<version>3.0.5.RELEASE</version>
</dependency>
Otherwise you get that non-intuitive error
Specify a custom LoadTimeWeaver or start your Java virtual machine with Spring's agent: -javaagent:org.springframework.instrument.jar
NOTE: You can use the spring version you want. I am using 3.2.5 for everything.
Want to warn everybody! This problem is very unclear.
Don't include this dependency to your project or include with provided scope.
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-instrument</artifactId>
<version>${thirdparty.spring.version}</version>
</dependency>
Otherwise agent class InstrumentationSavingAgent will load twice (first when loading agent, second while linking libraries) and spring will use second Class instance without injected Instrumentation
