I have created Spring MVC application without web.xml, completely using the java configuration but when I right click on the project I am not getting an option as Run on server which usually helps me to deploy my war into Tomcat 8.

I'm having trouble deploying my Spring MVC Webapp with the xsbt-web-plugin. When i'm using container:start everything works just fine, but when i'm trying to run the packaged .war file inside a tomcat instance the webapp isn't loaded. It is just starting a plain tomcat instance.
I had an error in my path that slipped through. I've overlooked this for days. Sorry.
I am working on a Java EE project with
jdk 1.8
wildfly 10.1.0 final
intellij idea 2016.3
The project has a web application module and an ejb module, and the structure is as follows:
And the two modules have already been deployed successfully
But when I tried to call the session bean, the ejb project went wrong and threw an error
Caused by: java.lang.NoClassDefFoundError: org/json/JSONArray
I use JSON in class DAOHelperImpl in the ejb module, and I've already add the dependency. I tried to put the jar in various packages such as /ejb/lib or /web/web/lib, but none of them are working.
What's wrong?
Move the jars libraries from /web/web/lib into
/web/web/WEB-INF/lib
By Convention the general folder for auto included jars is:
web-project-name/webContent/WEB-INF/lib

I am not aware how IntelliJ handles Java EE projects.
In Eclipse the EAR and WAR are in separate projects and can be assigned to each other.
I think this error is raised due to my bad understanding of how this web application together with the ejb module works: I deploy the web module and the ejb module separately, and it seems that wildfly can only link to the lib of the web module.
The solution is to deploy only the web application to the server and add the ejb module to the web application.
I am newbie in configuration. I have made Spring web application. When I run it on Intellij's Tomcat it works correctly. Now I would like to move to a different computer without Java, IntelliJ on it. Is it possible to do this only with Tomcat (XAMPP) installed?
To run a java web app (including Tomcat) you need to have Java on all computers at the level of your web application code.
i.e. if your web app is done with Java 1.8 then you have to have it there.
You treat the deployment as a standard java web application deployment check out this link:

I have built a small web app using Gradle. Things seemed to be going well using the embedded Jetty server, but not so well when I tried to copy the WAR file to a standalone server.
I used the gradle war plugin to assemble the war.
Running gradle jettyRunWar works fine.
Copying the war to the Jetty webapps folder and running Jetty fails with this exception:
java.lang.IllegalStateException: No such servlet servlet_name
But this very same servlet is found and used without issue in the embedded Jetty server.
The same issue happens if I manually copy the exploded war to the webapps directory.
The Spring web and Spring mvc libs are copied and present in the WEB-INF/libs directory, so it isn't an issue of not finding Spring (or is it?)
I'm using Jetty 9.1, and my web.xml file is configured for Servlets v3.
I'm also using Spring 3.2. The web app I'm writing is a RESTful service, using the #Controller annotations to route requests.
This should be as simple as copying the war over, but it seems not to be. At a bit of a loss at what to do here, any thoughts?
Thanks!
Sometimes the answer is staring you in the face...after posting I realized that I had my servlet-mapping before my servlet declaration. While this did not present an issue for the Gradle Jetty (not sure why), it made Jetty unhappy. Not sure why I changed the order to begin with...
In short, Jetty seemed to not find the servlet because it had not been declared yet.
I am new in jBoss and Portal
I download the jBoss Tools for Eclipse and go through the document to create Java Portlet http://docs.jboss.org/tools/3.1.0.GA/en/jboss_portal_tools_ref_guide/html/portlet_tools_tasks.html#deploying_to_portal
When I run the application in server and go to http://localhost:8080/portal/portal/default/default/
I cannot see my portlet, any idea why?
The default URL for JBoss is http://localhost:8080/portal.
