com.intellij.javaee.oss.admin.jmx.JmxAdminException: com.intellij.execution.ExecutionException

Question

When I run tomcat in IntelliJ IDEA, I get this below error, I have searched the StackOverflow, find nothing about my exception.

[2017-04-06 10:57:30,875] Artifact elecMaven-explored: Artifact is being deployed, please wait...
[2017-04-06 10:57:30,888] Artifact elecMaven-explored: Error during artifact deployment. See server log for details.
[2017-04-06 10:57:30,889] Artifact elecMaven-explored: com.intellij.javaee.oss.admin.jmx.JmxAdminException: com.intellij.execution.ExecutionException: /Users/luowensheng/Desktop/TestIOS/itheima1128elecMaven/classes/artifacts/elecMaven_explored not found for the web module.

But my artifact is really exists:

So, where is the issue?

I have tried:

add the below code to web.xml:

<context-param>
    <param-name>kmRootKey</param-name>
    <param-value>km.root</param-value>
</context-param>

But seems useless.

Answer 1

I also suffered with this issue... This occurs because

Tomcat doesn't find your project folder(application folder) to deploy. So

• Click on "Edit configuration" button, top right in intellij
• Configure Tomcat by clicking '+' symbol on left top and selecting "Tomcat server" then local.
• Give "Name" to your project as per need.
• Now in first tab "Server"...
• Set path to local tomcat directory in your system.
• Better change "Http port" 8080 to 808* (8086, 8087, 8088...)
• Go to second tab "Deployment"
• Under "Deploy at the server startup" Click on + symbol and select artifact. Now artifact having same name as your project-name should be listed in it. Then click OK

And unfortunately if above steps aren't helpful

• Go to the Deployment tab, click on edit button(pencil). It will open a new window called
  "Project Structure".
• Give "Name" and specify "Type" as Web Application: Exploded
• Under Output directory give the location of your project folder like
  (D:\Workspace\Project_Folder).

Answer 2

Select your artifact (File -> Project Structure -> Artifacts) and make sure Output directory points to correct directory (for example, path_to_webapp\target).

That's how I solved this problem.

Answer 3

The issue maybe you did not create the correct Artifact. The correct steps are:

When you create the Artifact, you should like this:

If you in the step3 choose the Empty, you maybe will get the error of title.

Then in Tomcat Configurations, you can deploy the Artifact like this:

And check it:

Restart your Tomcat.
