Is there a procedure to be followed to add external jars to a custom confluence plugin development environment

[angela simmons]

Hi All,

My custom plugin will require consumption of web service methods to realise certain events. As a result i have a few essential jar files which i easily configure in Java.

package com.atlassian.myorg;

import org.tempuri.FreewayAuthLocator;
import org.tempuri.FreewayAuthSoap;

import com.atlassian.confluence.core.ConfluenceActionSupport;
import com.atlassian.confluence.pages.AbstractPage;
import com.atlassian.confluence.pages.actions.PageAware;
import com.opensymphony.xwork.Action;
 
/**
 * The simplest action possible
 */
public class FreewayProjectAction extends ConfluenceActionSupport
{
    @Override
    public String execute() throws Exception
    {
    	String logonResult = "";
		try {

			FreewayAuthLocator freewayAuth = new FreewayAuthLocator();						
			FreewayAuthSoap freewayAuthSoap = freewayAuth.getFreewayAuthSoap();			
			logonResult = freewayAuthSoap.logon("freeway.username", "Password");
			System.out.println("LogonResult >> " + logonResult);

		} catch (javax.xml.rpc.ServiceException ex) {
			// TODO handle ServiceException
			ex.printStackTrace();
		} catch (java.rmi.RemoteException ex) {
			// TODO handle remote exception
			ex.printStackTrace();
		} catch (Exception ex) {
			// TODO handle custom exceptions here
			ex.printStackTrace();
		}
        return Action.SUCCESS;
    }
 
}

This is how my java class looks like .The 'FreewayAuthLocator' class are referenced from the jar files i have added via 'Configure Build Path'. And even in eclipse i am able to see the auto suggestions on the object of that class (By which i assumed that the class is available). How ever when i run this plugin using atlas-run the action trigerring this class results in a "No Class Def" found error.

Is there a compulsion to add the dependencies in pom.xml ?

You must add the dependency in your pom.xml, otherwise the jar won't be bundled and you'll get a NoClassDef error.

<dependencies>
  ...
  <dependency>
    <groupId>XXX</groupId>
    <artifactId>YYY</artifactId>
    <version>ZZZ</version>
  </dependency>
  ...
</dependencies>

If the jar is not in a maven repository, you can install it manually in your local repository using this command:

mvn install:install-file -Dfile=your-artifact-1.0.jar -DgroupId=XXX -DartifactId=YYY -Dversion=ZZZ -Dpackaging=jar

Hi Julien,

I added this dependency chunk in my pom.xml

<dependency>
            <groupId>freeway</groupId>
            <artifactId>axis</artifactId>
            <version>1.0</version>
        </dependency>

I have placed my jar file in the folder C:\jarhost\axis-1.0.jar
And i ran the command

mvn install:install-file -Dfile= "C:/jarhost/axis-1.0.jar" -DgroupId=freeway -DartifactId=axis -Dversion=1.0 -Dpackaging=jar

And this is the error i get is this

I also stumbled upon this https://confluence.sakaiproject.org/display/DOC/Adding+JARs+to+an+Application and tried it too. But it was unable to 'download' dependencies.

What am i missing ?

Looking for your help on this.

Could you try again without the space between "file=" and "C:/jarhost/axis-1.0.jar" like this:

mvn install:install-file -Dfile="C:/jarhost/axis-1.0.jar" -DgroupId=freeway -DartifactId=axis -Dversion=1.0 -Dpackaging=jar

i am having issue with this as well can anyone help with adding a external jar to my custom plugin.

I followed tutorial to create applet module by following this link:

https://developer.atlassian.com/docs/getting-started/learn-the-development-platform-by-example/convert-component-to-servlet-module

Whenever i add any external jar to the POM.xml it starts giving me error

These are lines I am adding to the pom.xml 

<dependency>
<groupId>joda-time</groupId>
<artifactId>joda-time</artifactId>
<version>2.9.4</version>
</dependency>

This is the error i get: It has something to do with osgi.wiring I have no clue about it

The project works fine without the jar though.
