How to deploy a Java web application on raspberry pi

Question

I have created a java web application using netbeans 8. The project works fine.

I need a help to put my project to the raspberry pi , so that when i type the ip address in the web browser it should run my java web application.

Also what are the things i needed to make my raspberry pi as a web server.

In my raspberry pi ,i already have java 8 ,apache2 ,tomcat8.

Answer 1

Step 1 Follow the instructions from Digital Ocean and install tomcat.

Step 2 After installing in netbeans, Go to Run->Clean and build.
Step 3 Goto Project folder and find the projectname.war file in dist folder.
Step 4 Rename the war to ROOT.war.
Step 5 Assuming you have followed all the procedure as mentioned in digital 
ocean from step 1, goto http://localhost:8080/
Step 6. Click Manage App .
Step 7  At the bottom there will be a browse button under upload war. Click it
Step 8  After selecting ROOT.war . Click deploy.

There you go. Now enter http://ip_of_pi:8080 from any browser in local network to view your site.

Port forward it to access it globally. (optional).

PS :- if you find error in the line curl -O in step 1 guide , replace the step by manually downloading tomcat.tar from Tomcat Official Site. Tomcat's Official Site to tmp folder.

Hope it helps someone
