    help with hot deploying jsp changes

    rathana bujji Newbie

      Hi All,

      Any help is greatly appreciated.I am trying but my attempts were not fruitful.

       

      I am using jboss-as-7.1.1.Final. My goal is to hot-deploy jsps when a change is done in jsp files etc., but jboss seems to be doing full re-deploy of webapp. This is coming in the way of development as i have to wait until jboss does full re-deploy(i have to log back in as http session is discared too).

       

      I did 2 settings after reading on these forums:

       

      #1.

      I have indicated development mode in JBOSS_HOME\standalone\configuration\standalone-af-jee.xml 

      <subsystem xmlns="urn:jboss:domain:web:1.1" default-virtual-server="default-host" native="false">
        <configuration>

          <jsp-configuration development="true"/>

        </configuration>....

       

      #2.

      Setup Auto-deploy exploded setting to true under deployment scanners in management console at port 9990

       

      I have put exploded version of ear in JBOSS_HOME\standalone\deployments

       

      so it looks like this

       

      myapp.ear  <--this is a folder
      META-INF
      mywebapp.war  <--this is a folder
          helloworld.jsp


      Now when i do small text change in helloworld.jsp, jboss 7 does the full re-deployment of webapp( taking a few minutes) instead of just deploying this 1 jsp so that i can test this change immediately in the next second.

       

      Pls help!!

          you should set auto-deploy-exploded not to 'true' as this will enable the scanner to watch each file and deploy the application on any change.

          set false and use the mwebapp.ear.dodeploy file to deploy and redeploy if necessary.

            Hi Wolf-Dieter,

            I set the auto-exploded to 'false', changed 1 jsp file in exploded war folder and force deployed using myapp.ear.dodeploy. Still the same issue. It brings down the entire webapp and redeploys entire webapp with new jsp change. I need ways so that the entire webapp does not re-deploy but just this 1 jsp change gets 'HOT'(not Auto) deployed. Thanks

              7.1.1 has known issue with jsp configuration not being aplied at all.

              this has been fixed few days after 7.1.1 was released, try using any version after that. i would recomend 7.2.0 / eap 6.1 alpha

                Hi Tomaz, Thanks for response.

                 

                I tried both 6.1.0.Alpha and 6.1.0.Final.

                 

                 

                Here is the configuration for my web subsystem.

                 

                <subsystem xmlns="urn:jboss:domain:web:1.1" default-virtual-server="default-host" native="true">
                <configuration>
                <jsp-configuration development="true"/>
                </configuration>
                <connector name="http" protocol="HTTP/1.1" scheme="http" socket-binding="http"/>
                <connector name="ajp" protocol="AJP/1.3" scheme="http" socket-binding="ajp"/>
                <virtual-server name="default-host" enable-welcome-root="true">
                <alias name="localhost"/>
                <alias name="example.com"/>
                </virtual-server>
                </subsystem>

                 

                 

                Here is the deployed app folder structure under deployments folder

                 

                 

                myapp.ear <--this is a folder
                META-INF
                mywebapp.war <--this is a folder
                helloworld.jsp

                 

                If auto deploy exploded setting is false, jboss does nothing when i edit a jsp in deployments folder so i am still seeing old page.

                 

                If auto deploy exploded setting is true, JBoss does a full redeploy of webapp, which i don't want. Problem with the full redeploy is that it brings down the webapp and the entire http session so i have to log back in again to test my change. This is not ideal in development time.

                 

                Pls let me know if something does not look right. Thanks.

                  From what I see in my EAP 6 installation, the version of the web subsystem is (at least) 1.4. Make sure you have that right.
