I need help here with the below issue. I am learning JMS and I am quite new to it. I came across a tutorial which I was following, however when I try to run this by selecting the project in eclipse I do not get an option to run on server. Is there a way we can run a simple java application on application servers?
Below is the link to the tutorial I am following
https://www.javatpoint.com/jms-tutorial
I have mostly worked with dynamic web projects for which the option is present to run on server.
I have not posted the code as it's the exact same as given in the tutorial.
For that you need to figure out which server(s) you want to deploy JMS. You can go with Weblogic or with ActiveMQ.
Below are the 2 reference links that would actually help you to resolve your query :

Yes, I would suggest you to go through spring-boot.
Here, you have an option to try a simple Hello World application
http://www.mastertheboss.com/jboss-frameworks/spring/your-first-jms-application-with-spring-boot
In the above example, you just have 2 java classes and one maven pom xml file to edit :)
Just try it out.
You can configure it to run from your eclipse too.
In/with spring-boot -
you don't have to do any web-server configuration on your own. Spring boot itself contains a web container.
It just creates a JAR file with which you can just run your application as "as your run a jar" which has your code + server.
And my last point is - you will get lots of support from different forums as spring boot is used widely.

Unlike spring-boot,
JakartaEE applications usually organizes application code
apart from server code.
Java web projects used to be packaged into war
or ear
files and the server was managed separately.
I am trying to find a project layout for JakartaEE projects that comply with separation but behaves more like a
springboot app and, in order to get it, i am exploring the embedded app servers approach.
So far, i am thinking on a multiproject layout, one with regular JEE style structure and another with an embedded app
server consuming the first one. Gradle and maven both supports it:
https://docs.gradle.org/current/userguide/multi_project_builds.html
https://books.sonatype.com/mvnex-book/reference/multimodule-sect-simple-parent.html
For the embedded app server i found these samples so far:
https://blog.payara.fish/what-is-payara-embedded?
https://www.ibm.com/docs/en/was-liberty/zos?topic=liberty-embedding-server-in-your-applications

https://www.eclipse.org/jetty/documentation/jetty-11/programming-guide/index.html#creating-helloworld-class
A good article on this topic follows:
https://www.baeldung.com/executable-jar-with-maven
For the project layout i don't have much ideas yet, i am only sure about the
separation of the two modules. A few questions so far:
should the embedded final jar file be an uber jar?
should the war/ear artifact be repackaged?
why this approach isn't more popular, given the clear success of sprin boot?
1) I have done the Moskito moskito-inspect-standalone-2.5.0.war integration with Java Maven web project good.
2) But i need to work on a plain(without Maven[pom.xml]) java web app to integrate Moskito, here even i dont need Moskito UI. i wanted to see the data in logs or some format, but not in UI
My Environment:
Windows 7
Eclipse 4.4 having a plain Java Web Application (without Maven)
How can i do monitor and inspect my classes effectively by generating log data?
First of all, you can download .jar file directly and include in your project directly. Maven is not required in this case.
Any additional configurations (thresholds, accumulators etc.) can be found here.
To configure custom output, take a look at configure LOG4J for Moskito page, that will help you to output results wherever you want.
I'm struggling with XML-less setup of a Spring project. Could you suggest some approaches to making this an iterative process? i.e. descirbe the steps of where to obtain configuration, how to find docs, which configs to define first, etc..
My goal is to implement a web app that supports websocket and I already found a very recent stock portfolio example https://github.com/rstoyanchev/spring-websocket-portfolio which works great, but when I try to create a simplest webapp that will have a very basic chat, I don't know where to start. I suppose this is all very new and not many are playing with this yet, but if you are, please share, I would be very grateful.
Update: My exact issue is how to dissect WebConfig java of the spring-websocket-portfolio project and rebuild it step by step to achieve a simple chat functionality. I have a spring project going, and it compiles and runs on tomcat 8 successfully(env is fine). the config file in question is this version: WebConfig.java.
What I am after is what is the best way to create something simple, a starting point, and build on top of it. By the way, the latest WebConfig.java has been much simplified by Rossen, but interestingly it has some compile issues and doesn't work.
Is using JSP Hot deployment a solution to publish new or updated content to avoid restarting the Java EE server (cannot hot deploy jar)? I should not use JSP to code a lot of java, but do I have any other solution?
With Tomcat, you can use the Parallel Deployment method. You will be able to deploy your new version and keep older one running with every users that has a session on it.
It is really simple when you are using WAR files, I recommend a simple script to delete older versions after couple of days for exemple, just to keep only few running versions.
You can get more informations here : http://tomcat.apache.org/tomcat-7.0-doc/config/context.html#Parallel_deployment
Did you have a look at JRebel yet?
I have a very basic question about web applications. I decided to ask on forum, because I don't exactly know, what to look for in google, I mean, i don't what key words should I use.
I read about maven and ant but I still don't understand some things. This is my project structure:
http://imageshack.us/photo/my-images/842/projectstructure.png/
I don't have any build.xml(for ant) or pom.xml(for maven) files, but anyway my project is properly running at my local computer. How is it possible if there are no configuration files ? I have only applicationContext.xml which is responsible for spring configuration, faces-config.xml for jsf 2.0 configuration and web.xml for servlet configuration. I tried to deploy it at openshift.com in this way: I exportet my project to .war file, and just commited and pushed it on server. The push ended well, but it does not work. Anyway I have to understand the basics of how my project works localy. Please give me any tips, where should I start. Thanks in advance
Here is a good wiki post about how to deploy a Java EE app on openshift:

It should put you on the right track.
