- Or you can Download the components from http://www.talendforge.org/exchange/ and search for Mongo instead of using Talend Big Data. But I would suggest use Talend for big Data for it.
 - The components will be zipped format , Unzip the same. In Talend Big data you will find the components in Component folder.
 - Copy these Unzipped Components to the installation Path of TOS. C:TalendTOS_DI-Win32-r84309V5.1.1pluginsorg.talend.designer.components.localprovider_5.1.1.r84309components
 - Copy the mongo-1.3.jar file in the component folder into the C:TalendTOS_DI-Win32-r84309-V5.1.1libjava In many systems you might not be able to see this file then go with ADMINISTRATOR priviliges.
 - optional for few systems——>>> Inside index.xml add save index.xml
 - Restart TOS
 
Then you will be able to use them as normal components.
