Tomcat in Intellij Idea Community Edition

Question

Is it possible to run a web application using Tomcat Server in Intellij Idea Community Edition   I tried to find some information about it but haven t achived any success

User · Answer

I am using intellij CE to create the WAR  and deploying the war externally using tomcat deployment manager  This works for testing the application however I still couldnt find the way to debug it    open cmd and current dir to tomcat bin  you can start and stop the server using the batch files start bat and shutdown bat  Now build your app using mvn goal in intellij  Open localhost 8080     Your port number may differ  Use this tomcat application to deploy the application  If you get the authentication error  you would need to set the credentials under conf tomcat-users xml

Intellij Community does not offer Java application server integration  Your alternatives are    buying Intellij licence  switching to Eclipse    installing Smart Tomcat plugin https   plugins jetbrains com plugin 9492 installing IDEA Jetty Runner plugin https   plugins jetbrains com plugin 7505 running the application server from Maven  Gradle  whatever  as outlined in the other answers    I personally installed the Jetty Runner plugin  Jetty is fine for me  I do not need Tomcat  and I am satisfied with this solution  I had to deal with IntelliJ idea - Jetty  report an exception  though

If you use Gradle  you can try my script  https   github com Adrninistrator IDEA-IC-Tomcat  This script will build files for web application  create a Tomcat instance  start Tomcat and load the web application

I used  Jay Lin s answer  Highly recommend it   If you never used Maven before and don t want to go deep into it  follow Jay Lin s answer  but also do this    right click on your project name -  Add Framework support -  Maven  Then install maven from here http   maven apache org install html  Do what it says  run the commands   Then install spring-boot from here https   mvnrepository com  Then follow the error messages if there are any - maybe you would need to install some other stuff  just google it and that mvnrepository com would come up   To install use this command    mvn install install-file -DgroupId  -DartifactId  -Dversion  -Dpackaging jar -Dfile path   replace path with where you downloaded the jar file  replace version  group and artifact id with info from mvnrepository com     Further errors I encountered    I had to create a class in src main java  with simple System out println command in main  and add  lt start-class gt main java Hello lt  start-class gt  in  lt properties gt  tag in pom xml  Btw  the pom xml should appear itself when you do the first action from my answer - copy paste Jay Lin s code there   Another error I got was connected to JAVA HOME variable and the verion stuff  Somewhy it thought jdk is 7th version and I was telling it was 8th  So I changed the java version tag in  lt properties gt  to this  lt java version gt 1 7 lt  java version gt     Now it works fine  Good luck everyone

Well the question is already answered  however what I am writing here is just my observation so other fellows in the community can save some of their time  I tried running a spring-mvc project using the embedded tom-cat in Intellij communit edition  First try I did was using the Gradle tom-cat plugin  however the problem that I faced there is the tomcat server just starts once  after that from the second start the build complains saying that a container is already running  There are so many open thread on the web about this  for some it works and for most of the people  almost 90  of the web threads that I broke my head with  faced the same problem of container not getting started the second time  The resolution is not there  After wasting a lot lot of my time  I finally decided to switch to maven tom-cat plugin and do the same spring-mvc setup with maven that I did with gradle and VOILA  it worked in the first short  So long story short  if you are setting up spring-mvc project in intellij community edition  please consider maven tomcat plugin  Hope this helps somebody s hours of exploration across various web forums

If you are using maven  you can use this command mvn tomcat run  but first you add in your pom xml this structure into build tag  just like this    lt build gt       lt finalName gt mvn-webapp-test lt  finalName gt         lt plugins gt             lt plugin gt                 lt groupId gt org apache maven plugins lt  groupId gt                 lt artifactId gt maven-compiler-plugin lt  artifactId gt                 lt version gt   maven compiler plugin version  lt  version gt                 lt configuration gt                     lt source gt 1 6 lt  source gt                     lt target gt 1 6 lt  target gt                 lt  configuration gt             lt  plugin gt         lt  plugins gt     lt  build gt

The maven plugin and embedded Tomcat are usable work-arounds  I like second better because you can debug  but actual web server integration is a feature only available in intelij paid editions
