JBoss AS 7.1.1 is 10 years old and since then the JDK has evolved quite a lot with modules. You need to specify the proper options for classloading or switch back to an old JDK (like 1.7).

Hmm, grabbing the name of the method which implements the body of the lambda out of a javap decompile is a neat trick for identifying the target method. I'm not sure why Byteman is failing to inject coe. Could you report this via the Byteman JIRA instance? I'll investigate and report the outcome on the JIRA. It may actually be possible to make this work.

How do you configure JBOSS to allow port 8080 over HTTPS?

Asked 2021-Jun-10 at 15:15

I have a JBOSS server (7.0) running an application that uses ServiceWorkers, which requires an HTTPS connection. I was able to update the standalone.xml and Eclipse launch configuration to bind my JBOSS server to my local IP (I'll worry about port forwarding later). Connecting to http://192.168.0.197:8080/[application] works just fine, except that ServiceWorkers won't start because it isn't an HTTPS connection. If I try https://192.168.0.197:8080/[application], the connection fails with the browser reporting "unable to connect".

I've researched several documentation sources and can't figure out what needs to be updated. Please forgive any terminology errors - my background is with application programming and networking tends to be the bane of my existence.

This is the pertinent standalone.xml configuration:

ANSWER

Answered 2021-May-28 at 17:24

This is because during the initial boot a logging.properties file is used to configure the log manager until the logging subsystem is activated. There are two options.

You copy an already configured logging.properties and standalone-ha.xml over to your image.
In a RUN command in your Dockerfile configure logging by starting the server, then executing the CLI script.

How to enable JMX in wildfly running in windows server 2016

Asked 2021-Apr-20 at 11:55

I'm running wildfly in windows server. Need to setup JMX to monitor remotely

I have tried adding JMX settings in standalone.conf.bat file and opened firewall port, but still not able to monitor using jconsole

Environment:

Wildfly 23
Redhat 1.8.275
Windows Server 2016

Things i tried:

Added the following settings in standalone.conf.bat file in bin folder

set "JAVA_OPTS=-Xms64M -Xmx512M -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m" set "JAVA_OPTS=%JAVA_OPTS% -Djboss.modules.system.pkgs=$JBOSS_MODULES_SYSTEM_PKGS -Djava.awt.headless=true" set "JAVA_OPTS=%JAVA_OPTS% -Djboss.modules.system.pkgs=org.jboss.byteman,org.jboss.logmanager" set "JAVA_OPTS=%JAVA_OPTS% -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.port=9010" set "JAVA_OPTS=%JAVA_OPTS% -Xbootclasspath/p:\wildfly-23.0.1.Final\modules\system\layers\base\org\jboss\logmanager\main\jboss-logmanager-2.1.18.Final.jar -Xbootclasspath/p:\wildfly-23.0.1.Final\modules\system\layers\base\org\wildfly\common\main\wildfly-common-1.5.4.Final .jar" set "JAVA_OPTS=%JAVA_OPTS% -Djava.util.logging.manager=org.jboss.logmanager.LogManager"

Service started without errors and was able to monitor using jconsole as localhost , but not from remote

Port was exposed in firewall settings though

Clarification Needed

Do i need to disable default management port 9990 in standalone .xml file for this to work

but if thats the case i'm able to monitor using the jmx port in local

Any help or suggestions please

Thanks in advance

It worked for me with below settings at last. I was missing the below property -Dcom.sun.management.jmxremote.rmi.port=

Complete Property looks like this

set "JAVA_OPTS=%JAVA_OPTS% -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=-Dcom.sun.management.jmxremote.rmi.port= -Dcom.sun.management.jmxremote.local.only=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false"

Apart from this i setup the SSL for the wildfly

It worked for me

In the web console go to Runtime -> Server -> Web -> Deployment then select the deployment you want and click "View". From there you can see the servlets from the Servlet tab on the left.

In CLI you can execute something like the following to list the names.

adding a java agent to wildfly10.1.Final server

Asked 2021-Mar-30 at 09:29

Good afternoon everyone,

My problem: I can't seem to make a java agent (https://github.com/krpors/delver) work on WildFly10.1.final

I deployed the same demo spring-boot application(war) on both tomcat and Wildfly

adding the agent to tomcat was straight forward and easy (having only to add the -javaagent:... argument to CATALINA_OPTS) the tomcat server started and the agent worked exactly as expected (listing all the methods in the specified packages in the XML config file of the agent and tracking how many times the method was called and for how long ...)

when everything seemed to work flawlessly with tomcat and the agent I tried to add the delver agent to WildFly and that's when everything started to go wrong.

It took me solid 4 days to get the wildly 10.1 server to start with the agent by adding these configs :

Install byteman

If you have downloaded a binary release then unzip it into a target install directory. This directory contains everything you need to use byteman. You should set environment variable BYTEMAN_HOME so that it points to the target install directory. If you have downloaded a full release then unzip into a target release directory. The release includes a subdirectory called install which contains everything you need to use byteman. You should set environment variable BYTEMAN_HOME so that it points to the install subdirectory. If you execute command 'ant install' in the target release directory then this will rebuild the byteman release from the sources overwriting the original contents of directory install. The install directory contains the following subdirectories. bin -- contains Unix scripts to simplify: using Byteman (bmjava.sh); typechecking Byteman rule scripts (bytemancheck.sh); communicating with the Byteman agent listener (bmsubmit.sh); and installing the agent into a running JVM (bminstall.sh). You will need to change the permissions of these files in order to execute them directly from the command line. docs -- contains the Byteman Programmer's guide and license information for Byteman plus the third-party software it uses. lib -- contains the Byteman agent and rule engine (byteman.jar); the subset of this code needed to compile/run the submit client (byteman-submit.jar); the subset of this code needed to compile/run the install client (byteman-install.jar). sample/lib -- contains helper code for the sample scripts. sample/scripts -- contains example rule scripts showing how to use Byteman. contrib -- contains software contributed by other Byteman users.
