How to deploy created .jar file in Apache Tomcat server in Eclipse IDE?

Question

I'm stuck into the process of deploying created .jar files in Eclipse.

Eclipse is at location: E:\\eclipse

Web project is at: E:\\Runtime_Testing\\src\\study_to_night

Tomcat is at location: C:\\apache-tomcat-7.0.54-windows-x64

Meanwhile, steps followed for creating jar files in Eclipse:

1. Right click on your Java Project and select Export.
2. Expand the Java node and select JAR file.
3. In the JAR File Specification page, checked the option which says "Export Java source files and resources"
4. Selected the export destination as: E:OneForAll.jar ; OneForAll being the name of my .jar file
5. Checked the option` "Compress the contents of the JAR Files"
6. Next ---> Finish.

On following the above steps, an executable JAR file is created at the specified location. Just to check if all the files have been extracted in the .jar component, when I chose "Extract files" option, all source files were traceable. However, on double-click it throws Error: Invalid or corrupt jarfile 'E:OneForAll.jar' .

I feel I'm lost. Is there something I missed out? What went wrong?

Could someone walk me through the steps to do this manually ?

Answer 1

So you have it running successfully within eclipse? But now you want to deploy this tested web app?

Then

1. Right click on your Java Project and select Export.

2. Expand the Web node and select WAR file.

This exports the WEB-INF and related files that tomcat needs.

Answer 2

Apache tomcat is a web container you cannot deploy a jar in tomcat server. If you created a web application then export your application as war file and put it in tomcat webapp directory, start the server and your war will be deployed.

if you have lots of jars then still you need to bundle them as war
