I am trying to run my war file using xsbt-web-plugin. My war itself does not contain tomcat-jdbc-pool jar and javax-servlet-api. I tried using container configuration. But sbt complains configuration does not exist.
If I use provided configuration, webapp-runner fails.
I am sure I am missing something. But unable to figure it out.
WARNING: Failed to register in JMX: [javax.naming.NamingException: Could not load resource factory class [Root exception is java.lang.ClassNotFoundException: org.apache.tomcat.jdbc.pool.DataSourceFactory]]
What version of xsbt-web-plugin are you using? Can you post the contents of your sbt build configuration?
The Tomcat plugin in xsbt-web-plugin relies on webapp-runner, which does not appear to bundle the tomcat-jdbc library. You can add it via containerLibs in Tomcat:
enablePlugins(TomcatPlugin)
containerLibs in Tomcat += "org.apache.tomcat" % "tomcat-jdbc" % "8.5.15"

I have an OSGi Bundle and a servlet. Now I want to access the bundle from the servlet. For that purpose I use the following in the servlet:
#Resource
BundleContext context
...
ServiceReference ref = context.getServiceReference("package.MyOSGiServiceInterface");
MyOSGiServiceInterface service = context.getService(ref);
The Problem is that my servlet doesn't know MyOSGiServiceInterface 'cause that is defined in the OSGiBundle. In Eclipse I added a reference to the bundle Project in my Build Path. But at runtime it obviously can't find it.
To solve that Problem I played around with
(in bundle manifest)
Export-Package: package-of-osgi-service-interface
(in servlet manifest)
Import-Package: package-of-osgi-service-Interface
Dependencies: ...,deployment.MyBundle
But I couldn't solve it.
Whats the missing step? How can I tell JBoss to add the package containing MyOSGiServiceInterface in OSGiBundle to the class path?
Thanks for answers!
(JBoss AS 7.1.1)
--> error message <--
Eventually I solved it. I had to put the right combination of settings together to reach my goal:
Deploy the bundle per: File - Export - "Deployable plug-ins and fragments" into folder: "jboss/standalone/deployments"
Bundle-Manifest:
Bundle-SymbolicName: TestBundle
Bundle-Version: 1.0.0
Export-Package: "package-which-includes-my-service"
Servlet-Manifest:
Dependencies: org.osgi.core,org.jboss.osgi.framework,deployment.TestBundle:1.0.0
Import-Package: "package-which-includes-my-service"
I am testing JBoss AS 7 prior to deployment with a .war file of an app running in a different server.
I get this error when I try to log onto the database via the app:

In some forums, they suggest adding the commons-codec jar, but I already have it in JBoss, right? (in here: jboss-as-7.1.1.Final/modules/org/apache/commons/codec/main/commons-codec-1.4.jar)
OSGi is not activated, frankly I have no idea to what purpose it serves, but when I try to activate it it messes with my war as it fails to deploy...
I have JDK, but no JRE if that's any help.
JBoss AS 7 does not use OSGi by default for modular class loading. It uses JBoss Modules so this has nothing to do with OSGi.
What you need to do if you want to use the commons-codec provided with JBoss AS 7 is add a dependency to your deployment.
Modules are not visible by your artefact classes automatically. You have three possibilities:
Define a global module in your standalone.xml
http://javahowto.blogspot.de/2012/09/how-to-create-global-modules-in-jboss.html
This module will be used by all artefacts you are deploying on Jboss.
Put it into your war artefact, into the lib folder. You can do that with Maven.
Define an explicit dependency within your Manifest. https://docs.jboss.org/author/display/AS7/Class+Loading+in+AS7

I'm trying to add the automation libraries to my project in Flash Builder so we can automate our testing.
I've added this to the additional compiler settings:
-include-libraries+="${flexlib}/libs/automation/automation.swc","${flexlib}/libs/automation/automation_agent.swc","${flexlib}/libs/automatio n/automation_dmv.swc","${flexlib}/libs/automation/automation_spark.swc ","${flexlib}/libs/automation/automation_air.swc","${flexlib}/libs/aut omation/automation_airspark.swc","${flexlib}/libs/automation/qtp_air.swc"
and -locale nl_BE fr_BE
After compiling this I get 2 errors:
Unable to resolve resource bundle "automation_agent"
Unable to resolve resource bundle "qtp_air"
However, in my nl_BE and fr_BE folders under flex_sdk\frameworks\locale\ the automation_agent_rb.swc and qtp_air_rb.swc are present.
If I switch to en_US, it works fine.
Can somebody explain to me why Flash Builder can't find these resource bundles?
Try explicitly adding automation_agent_rb.swc and qtp_air_rb.swc to your library-path as well.
I paste one jar in repository/components/lib/ as dependence, but the wso2app does not find it when accessing the service, it throws the exception:
java.lang.ClassNotFoundException: Class Not found : br.org.test.MyClassTest
How can I fix this? Where should I put the jars for dependencies?
Try putting the jar file in $CARBON_HOME/repository/components/extensions directory and do not forget to restart the server after adding the library.
Source: How to Add External Jar Libraries to WSO2 Carbon based Products.
After a long research i finally was able to solve this by putting my dependencies in /lib/runtimes/ext.
Following this documentation. https://docs.wso2.com/display/AS530/Configuring+Runtime+Environment
I am trying to add jbox2d as a dependency to my project in netbeans (playn-jbox2d-1.1-SNAPSHOT.jar), but at run time, I get:
Exception in thread "main" java.lang.NoClassDefFoundError: org/jbox2d/collision/shapes/Shape
All other classes can be accessed fine, just not Shape.
I simply right clicked dependencies in my core directory and did add dependency and searched for jbox2d.
Anyone know what could be wrong?
What version of jbox2d do you have, as a dependency? You can crosscheck in the dependency jar file, if that class (Shape.class) exists or not?
EDIT: Most of the times, 'NoClassDefFoundError' happens due to incorrect classpath settings or when there's more than one class (or jar file) in the classpath, with the same namespace.
