Convoyer Unable to instantiate Action
Asked by ket.pjwstk:

```
Hi,

I am trying to override the editpage action using convoyer, however I get the following error: 

com.opensymphony.xwork.XworkException: Unable to instantiate Action, com.atlassian.confluence.pages.actions.EditPageAction,  defined for 'editpage_2' in namespace '/pages'com.atlassian.confluence.pages.actions.EditPageAction    with nested exception 
java.lang.ClassNotFoundException: com.atlassian.confluence.pages.actions.EditPageAction	at com.opensymphony.xwork.DefaultActionInvocation.createAction(DefaultActionInvocation.java:220)	at com.opensymphony.xwork.DefaultActionInvocation.init(DefaultActionInvocation.java:272)	at com.opensymphony.xwork.DefaultActionInvocation.<init>(DefaultActionInvocation.java:65)

My convoyer-config is
<?xml version="1.0"?>
<conveyor-config>
		<package-override name="pages" namespace="/pages">
			<action-override name="doeditcomment" inherit="true">
				<result-override name="input" type="velocity">/templates/editcomment-preview.vm</result-override>
			</action-override>
			
			<action-override name="editpage" inherit="true">
            	<result-override name="error" type="velocity">/templates/editpage.vm</result-override>
            	<result-override name="input" type="velocity">/templates/editpage.vm</result-override>
            </action-override>
	
		</package-override>
	</conveyor-config>

In my atlassian plugin xml I have:
	<conveyor name="Action Conveyor" key="actionConveyor" resource="/conveyor-config.xml"/>

and plugin-version=2

I also added dependencies in pom.xml

Any idea?

You will probably also need to import some other packages once you've done that, such as com.atlassian.plugin, com.atlassian.user, etc, depending on what packages your Actions and components are using. Example is below:

```
&lt;Import-Package&gt;com.atlassian.confluence.*;version="[3.4,4)",etc,etc.&lt;/Import-Package&gt;
```

body: Hi Raffy,Firstly, in case you haven't found them, read the docs here:<https://studio.plugins.atlassian.com/wiki/display/LIBCNV/Conveyor+Plugin>Secondly, the Conveyor Plugin will be installed alongside your plugin, not bundled inside it. You can bundle them together in an OBR file, rather than a .jar file.Thirdly, if you're installing into Confluence 4, change the above to '\[3.4,5)' so that it will match to Confluence 4.

body: Hi David. Thank you very much for your answers. I am installing the plugin into Confluence 4. What does the parameter '\[3.4,5)' mean?


author: dy raffy
body: Could you please tell how? I am trying to use the conveyor-Plugin too, But getting a lot of Problems with it.

Did you bundle the conveyor-Plugin into yout Plugin or just used it and installed it manuelly?

Wich Packages did you add to the \<import-Package\>...\</import-Package\>?

Is it exactelly as above to override the File editcomment-preview.vm?
