Hot deploy on JBoss - how do I make JBoss “see” the change?

Question

I am developing a Java EE application that I deploy over and over again on a local JBoss installation during development. I want to speed up the build by hot deploying my ap

Solution for Netbeans 8.02 and 8.1 IDE and JBOSS EAP 6.4:

1. From the services tab of Netbeans, add JBOSS server to your "servers" node.

2. If you are using MAVEN, netbeans compiles files and maven copies files to ./target directory. You need to create a symbolic link from .\target to JBOSS_HOME\standalone\deployments. Under windows, an example command would be

   cd %JBOSS_HOME%\standalone\deployments mklink /d MyWebApplication.war %PROJECTS_HOME%\MyWebApplication\target\MyWebApplication-1.0.0

   The above creates a symbolic link from %JBOSS_HOME%\standalone\deployments\MyWebApplication.war to \target\MyWebApplication-1.0.0 which is where maven transfers all files after compilation, or after a jsp, html or any other file changes.

3. Last think to do is to create a CentralManagement.war.dodeploy file in %JBOSS_HOME%\standalone\deployments. This file will tell JBOSS to deploy the war "file" as a web application

You should try JRebel, which does the hot deploy stuff pretty well. A bit expensive, but worth the money. They have a trial version.

I have had the same problem, but think I've got it under control now.

Are you using eclipse or command line or ??

When I use the command line, I think I did "seam clean" or "seam undeploy" or maybe even "seam restart" followed by "seam explode". I probably tried all of these at one time or another never bothering to look up what each one does.

The idea is to remove the deployed war file from TWO places

1. $JBOSS_HOME/server/default/deploy
2. $PROJECT_HOME/exploded_archives

I'm pretty sure "seam undeploy" removes the 1st and "seam clean" removes the 2nd.

When I use eclipse (I use the free one), I first turn off "Project/Build Automatically" Then when I am ready to deploy I do either Project/Build Project or Project/Build All depending on what I've changed. When I change xhtml, Build Project is sufficient. When I change java source Build All works. It's possible these do the same things and the difference is in my imagination, but some combination of this stuff will work for you.

You have to watch the output though. Occasionally the app does not get cleaned or undeployed. This would result in not seeing your change. Sometimes I shut down the server first and then rebuild/clean/deploy the project.

Hope this helps.

I am using JBoss AS 7.1.1.Final. Adding following code snippet in my web.xml helped me to change jsp files on the fly :

<servlet>
    <servlet-name>jsp</servlet-name>
    <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
    <init-param>
        <param-name>development</param-name>
        <param-value>true</param-value>
    </init-param>
    <load-on-startup>3</load-on-startup>
</servlet>

Hope this helps.!!

I had the same problem in my bundle: (Eclipse IDE + JBoss server adapter) + JBoss AS 7.0.1 (community project).

My solution is very simple - you should go to JBoss administrative panel (by default localhost:9990), there in profile settings open Core - Deployment Scanners. Turn on Autodeploy-Exploded (set to true), and by your wishes you can set scanner time (by default 5000 ms) to appropriate for your (I set to 2000, for more fast incremental publish in Eclipse when I make changes to projects). That's it. Now JBoss makes HOT deploy not only for HTML (JSF, XHTML and so on) files, but also takes care of POJO classes (beans and so on) files.

Found the solution on this link:

What to do:

1. configure exploded war artifact to have extension .war
2. deploy exploded artifact to WildFly or Jboss
3. configure IntelliJ to Update Resources on Update Action

When I modify a page (web), I update and when I refresh web browser: is all there with my mod. I did configured Jboss for autoscanning (not sure it did helped)
