Custom Component not loading

[Anonymous]

I have created a plugin project whose functionality is to add a menu item. I exported that plugin project to TOS into "\TOS_DI-Win32-r118616-V5.5.1\plugins" folder. When I restarted TOS, that plugin works fine means a new menu item is loaded. Now I tried to integrate this plugin to my custom component through FIELD as EXTERNAL and in HEADER SECTION added EXTENSION="name of the plugin" in the XML file of my custom component. I also added in "TOS_DI-Win32-r118616-V5.5.1\features\org.talend.tos.components-feature_5.5.1.r118616\feature.xml" file. Now when I restarted TOS my custom component is not visible.
I have checked the .log file,

Plugins manifest file contains like this:
Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Menu
Bundle-SymbolicName: org.talend.designer.menu; singleton:=true
Bundle-Version: 5.5.1.r118616
Bundle-Activator: org.talend.designer.menu.Activator
Bundle-Vendor: .Talend SA.
Require-Bundle: org.eclipse.ui,
 org.eclipse.core.runtime
Bundle-RequiredExecutionEnvironment: JavaSE-1.7
Bundle-ActivationPolicy: lazy
I have doubt about java version 1.7(because I have seen other posts saying that JDK1.6 is recommended than JDK1.7)
Can anybody get me out of this...

Hi 

 Now I tried to integrate this plugin to my custom component through FIELD as EXTERNAL

The filed such as CHECK, TABLE, LABEL etc have to be defined first before it is used, I am not sure a plugin is supported to be a field.
Best regards
Shong

i have a similar problem, my plugin is an extension that works just fine in openstudio, however Enterprise version fails to load it. I've tried everything. I use the same settings as in open studio.
Also you should check if your manifest file contains the correct values. I've created a guide a few months ago, if anythign is missed please feel free to comment, so I can add the information. https://community.talend.com/t5/Design-and-Development/resolved-Create-custom-action-for-a-button-on...
