I am new to the Jboss server.
I am using wildfly for hot code deployment. And have two dynamic web projects.
I can able to deploy and use hot deployment feature when i deploy one app at a time.
But when i add two DWPs to server and start it, deployment is failing for both application. Is there any setting that we need to enable to allow multiple projects?
I am using eclipse keplar, java 7, jboss 8.
It should not be a problem to deploy on a standard wildfly many ear/war-files.
It is possible that you copy and pasted the project ? In this case the web-context could be on both projects the same.
After you start your wildfly you should see two files like .war.failed or
-1.0.0-SNAPSHOT.ear.failed
could you post the error messages?

I have made a small maven based web application in VSCode and trying to deploy it on JBoss using the Redhat Server Connector Extension.
But the hot deployment of the class files does not work in simple running JBoss server.
But Hot deployment does work in debug mode as 'Hot Code Replace' by setting the property 'java.debug.settings.hotCodeReplace' to 'auto'.
My inputs are from below links:
https://devblogs.microsoft.com/visualstudio/hot-code-replacement-for-java-comes-to-visual-studio-code/
and other SO links like:
How do I get Java "hot code replacement" working in JBoss?
Hot deploy on JBoss - how do I make JBoss "see" the change?
But it couldn't help.
Can you suggest something more about how it is simply possible in running JBoss?
(PS: Auto Build feature in VSCode is already enabled.
And It works fine in eclipse).
Hot deployment of web applications in VSCode's integrated RedHat Server connector can occur in following ways:
Exploded war folder: A folder is extracted from the original war and deployed to JBoss using the Exploded option. Here, the static changes like change in jsps and HTML are automatically reflected in the running application.
Hot code Replacement: Hot code replacement (HCR) is a fast debugging technique in which the Java debugger transmits new class files over the debugging channel to another JVM.
HCR only works when the class signature does not change; you cannot remove or add fields to existing classes when using HCR. However, HCR can be used to change the body of a method.
(source: https://devblogs.microsoft.com/visualstudio/hot-code-replacement-for-java-comes-to-visual-studio-code/)
Maven Install/build: It is actually not a preferred technique which someone will want but it is useful also. In this technique, you run maven: install which builds the project again and install it onto the server again.
Currently, VSCode for java and the server connector extension are new as compared to already available IDEs like Eclipse. So, we might expect more powerful functionality in coming future.
I have a Java 1.6.0 web application that I am developing using a Kepler Version 2 Eclipse development environment. I am using an Oracle Weblogic Server Administration Console 12c.
I'm running the app locally - and trying to debug it. Instead of stopping at any of the breakpoints I've set - I get the following error:
When I installed the application to Weblogic, I ran the Weblogic console and then installed the application by adding the ear file.
I thought I did everything exactly the same as previous web applications I've done this way - but I was always able to debug those applications.
Also - one other thing that is different. When make any changes and re-build the ear file - I actually have to delete and reinstall from the Weblogic console for the changes to take place. I'm thinking this might be related.
Any suggestions?
Thanks!
Have a jar file added to a build path in any of the projects that
include the classes in your project
We can create a Java Tomcat Project in eclipse. As per my knowledge its a Java project with a WAR structure. I have searched a lot on web but did not get any satisfactory answer.
I want to know what is the need of Tomcat Project when Dynamic Web Project is there?
Are they different in project hierarchy only or there is any other difference?
Is it specific to Apache Tomcat i.e. can't be deployed on any other server like JBoss?
Thanks.
My firm is change the development environment, looking for some tricks and tips on how to work in the new environment.
The current environment is Eclipse and Tomcat. We are developing web applications with Spring, Web Flow, and MySQL..
The new environment is going to be Eclipse, Jboss AS7 and Maven.
Question 1:
Now for the questions as the current time we run tomcat on the local workstations and I can use eclipse to write my code and then just click on “Run On Server” and eclipse will build the war file and start tomcat.
With the new environment it does not look like Eclipse can start and stop and depoy right to Jboss AS so we are running a command line: mvn jboss-as:deploy does anyone know a better way?
Question 2:
Debugging.. Does anyone know how to get debugging working with eclipse and jboss as7
1) You can use "Run On server" with JBoss As 7 just like you do it with Tomcat. Just add new server in Eclipse for JBoss As. One difference comparing to adding new server for Tomcat is that during new server definition you should also create new runtime Environment for JBoss (if you haven't done this before) but this is very easy and intuitive. And there is a lot of examples in internet.
2) Debug is working with JBoss As very good too. If you start server from eclipse, then you can use debugger like you have used it before for Tomcat. If you run your server from command line without Eclipse, you can use remote debug from eclipse (as I remember Dubug as.. -> Remote Java Application and then specify there project, host and port).
I have an enterprise application running on a WebLogic server.
When I modify any Java class, I have to build the .ear file and deploy to the server every time. Even for a small modification, I need to build the whole application and deploy to the server. The server is taking around 10 minutes to do this.
Is there any other way to do this?
When I was working with Tomcat, we used to update the .class files directly in the webapps project folder so that we didn't need to re-build the entire application.
Yes - there is a feature called FastSwap.
Using FastSwap to speed up dev
Using FastSwap Deployment to Minimize Redeployment
When you create a weblogic domain, you define it will be started in Development or Production mode.
To modify that, update the value of production-mode-enabled to true or false in config/config.xml
For more details check the following link or Weblogic documentation.
Difference between DEV and PROD mode in Weblogic 10.3
About your question on Weblogic Plugin, I suppose your're talking about OEPE (Oracle Enterprise Pack for Eclipse), which will deploy your application to a running domain that will be in dev or prod mode according to the mentioned in the config.xml
