I'm completely new to OSGi and I'm working on the development of an OSGi bundle and I want to debug my code (set breakpoints, step by step run, variable lookup, ...).
I have my virgo server listening on port 8001.
How can I do that ?
I'm using Springsource Tool Suite 3.0 and my bundle is running on a remote virgo server.
Thanks for any hint you can give me.
Marco.
Take a look at this answer,

I've set up a VM with a wildfly instance.
I'd like to be able to debug my web application from eclipse.
I've took a look on the web, however, I've not been able to figure out how to do it.
Any ideas?
Install JBoss Tools into Eclipse IDE, and then you can use the features described in http://tools.jboss.org/blog/2015-03-17-debugging-an-externally-launched-wildfly.html
I really need to debug my code by the use of breakpoints, however this seems a complex undertaking with an OSGi container.
I have Eclipse and Felix (both the latest). My project is a raw OSGi project, I am not using PDE, just maven bundle plugin to generate the bundles and then copy them to the /bundle folder in felix, then I perform java -jar bin/felix.jar and the project runs. So no fuss here.
However I cannot debug the application that way. I've tried to read the docs (http://felix.apache.org/documentation/development/integrating-felix-with-eclipse.html) but they are outdated/broken and cant make them work...
How can I debug this? Will I have to avoid using OSGi just because debug is not supported...?
Thanks!
Have you considered using an IDE tool like bndtools to do the debugging? You can create a repository from your folder of bundles and run them using a bndrun file. This gives you a debug environment in Eclipse which sounds to be what you want. The bndtools website is here.
Bndtools also does a lot more, but it sounds as if you're happy with your existing Maven build. The tutorial runs through setting up a basic workspace, but the main thing you'll be interested in is Running a framework
Start felix with the following parameters to enable remote debugging.
java -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1044 -jar bin/felix.jar
After you can connect via Eclipse Remote Debugging to your Felix Container.
Run
Debug Configurations
Remote Java Application
Choose as project the project/sources you want to debug
Configure port to 1044
Trigger debugger by clicking on debug
I have a Java Web Service project which was just handed over to me by a colleague who just resigned (no one is assisting me in my new company). Im new to Java (J2EE) and my background is .Net + frontend + azure so I am pretty much very confused with setting up and running the java project. Also, Since my background is .Net Im referencing everything with how things work in Visual Studio from running a project, setting up a project to setting up and debugging a WCF project which I realized now is very different from eclipse + java.
I would really appreciate if someone could explain to me how I can run this project which is supposedly a java web service (as I was told)?
First I have a project that is like this:
Im assuming that the project boxed as blue is the webservice (and the rest are just libraries)? Is this correct? if so how do I run and debug the project using eclipse
Second when I click on debug as -> debug on server this is all I see:
Another colleague told me to install JBOSS (I haven't installed a server in eclipse) because that is what they used. Is there good documentation (step-by-step guide) on how to install JBOSS to run in eclipse. Im assuming that JBOSS + eclipse is like IIS express + Visual studio. Are there also other alternatives to JBOSS + eclipse like perhaps tomcat + ecplise that I can configure.
I really really find it hard to setup the java web service project in eclipse I have little to no prior experience with java j2ee programming especially with web services so any clarifications with my questions would be much appreciated. To sum up:
How would I really know that the project is a java webservice?
If so, how do I run the project and host the project using debugging in eclipse with tomcat or jboss?
I would appreciate if anyone can point me to the right direction of figuring out the source code
From here we can only guide you, you will have to go through some tutorials to understand how java projects work.
Your project is a webservice project according to your web.xml file because its having context params for rest.
the context param sets a front url to your webservice which in this case is gametime.
Check these tutorials and you will understand how it works
http://www.mkyong.com/tutorials/jax-rs-tutorials/
Create simple examples given in the above tutorial and then you can execute your's program
Jboss is a application server which we use to run our app.
You can install jboss in eclipse or you can use it externally also.
To install eclipse and jboss you can follow the link
http://theopentutorials.com/tutorials/java-ee/installing-jboss-tools-in-eclipse/
The other option is to download eclipse and jboss seperately
and use them.
Go to jbosshome/bin
If you download both of them seperately
then in that case for jboss
Invoke the add-user.sh or add-user.bat script. ...
Choose to add a Management user. ...
Choose the realm for the user. ...
Enter the desired username and password. ...
Choose whether the user represents a remote JBoss Enterprise Application Platform 6 server instance. ...
Enter additional users. ...
Create users non-interactively.
After this go to eclipse and follow steps of below link to add jboss to eclipse

A Java web application among other things has a predefined directory structure including folders named WEB-INF, WEB-CONTENT etc.
On how to deploy a web application to Tomcat via Eclipse you can follow the steps in this tutorial.
I run JBoss on java7 DCEVM http://dcevm.github.io/
It's possible to Hot Swap any type of code changes from IntelliJ connecting to standalone Swing application (using remote debug; VM startup parameters -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=2222).
But when I try to do something similar when debugging application running on JBoss (connecting debugger remotely same VM parameters as previously) IntelliJ claims that hot code replace succeeded, however application doesn't change behavior as it should.
Do you have any ideas what could be the reason?
Is it connected somehow with the Java EE classloading model?
Has anyone experienced such problem?
Is it possible to hot swap code with DCEVM in JBoss using remote debug?
Try to use the following project: https://github.com/HotswapProjects/HotswapAgent. It uses DCEVM and solves hotswapping problems inside many java frameworks (Spring, JSF etc..)
I'm trying to run the JHipster application via my Eclipse Juno, using jdk 1.7.
The app seems to be loading properly (no console errors), but when i'm trying to reach the server with the client side (or via Postman, by sending a request to the REST servlets in port 8080), it's not responding.
However, when i'm running "mvn spring-boot:run" in the command shell, the server is loaded successfully and is responding to the exact same requests. Also, I managed to run the same command via eclipse with some maven configuration but it seems to be running only the target files (jars) and not the source code. I still haven't been able to run the source code of this app using eclipse in order to properly debug it.
Any suggestions?
Thanks!
So the answer is quite trivial, but since I spent several hours to reach it, it might save some time for others-
Download & install STS IDE.
Import the project as existing Maven project.
Run/Debug the project.
I tried to run it via Eclipse the whole time (wasn't familiar with STS to be honest) and this probably needs some extra configuration (another comment with explanations on eclipse configuration will be much appreciated). Once you work with STS, it's easy.
You should not need STS, just Eclipse with the J2EE stuff.
I've imported the sample jhipster in Eclipse (without STS) as a Maven project and everything was OK, after installing the maven dependencies.
To run the project, run as an application and search for the Application (com.mycompany.myapp.Application)
This app works for me: https://github.com/jhipster/jhipster-sample-app. It is stuck on Boot RC5 which probably means it's a bit old. Maybe Julien can comment on that (or update it)?
