Launch JBoss Wildfly 10

[ruedige...@googlemail.com]

Hi!

I'm trying to launch a JBoss Wildfly 10.0.0 with the HotSwapAgent from within IntelliJ IDEA.

I pass `-ea -XXaltjvm=dcevm -javaagent:<path-to>/hotswap-agent.jar` (where `<path-to>` is my real path) as VM options, but I get this stacktrace during startup:

... and the deployment fails.

I understand that the JBossModules plugin is available, but it doesn't seem to be able do it's job. Briefly looking at the source of org.jboss.modules.ModuleClassLoader I have the impression this could be an incompatibility with Wildfly 10.

BTW: the JBoss-Module is not in the list of plugins on the HotSwapperAgent website.

  Hi,

I didn't test it on Wildfly 10.x. It looks there is something new that break the HA functionality.  We should fix it. JBossModule was not in last 0.3 release so that it is still not mentioned in the README.

You might want to try https://github.com/alpapad/HotswapAgent/tree/wildfly10

This is tested and working in wildfly 10.  The changes in this repo is slowly being pushed to  HotswapAgent master but they are not all there.

If you are using maven/eclipse, then this configuration has worked for me:

In you pom(s) add:

<build>

....

<resources>

            <resource>

                <directory>${basedir}/src/main/resources/</directory>

                <includes>

                    <include>**/hotswap-agent.properties</include>

                </includes>

                <filtering>true</filtering>

            </resource>

            <resource>

                <directory>${basedir}/src/main/resources/</directory>

                <excludes>

                    <exclude>**/hotswap-agent.properties</exclude>

                </excludes>

                <filtering>false</filtering>

            </resource>

</resources>

....

</build>

And then have the file hotswap-agent.properties in src/main/resources. Mine looks like this:

----

# web fragment or jar

extraClasspath=${project.build.outputDirectory}

autoHotswap=true

#LOGGER=debug

---

# war

extraClasspath=${project.build.outputDirectory}

watchResources=${project.basedir}/src/main/webapp

autoHotswap=true

#LOGGER=debug

--

For standalone I use the following opts (linux):

JAVA_OPTS="-XXaltjvm=dcevm -javaagent:/home/path-to-hotswap-agent/hotswap-agent.jar -Xverify:none -noverify"

(the no verify just makes classloading faster, not for production use)

Regards,

Alex
