I am writing a deployment extension using java code in SDL Tridion.
My requirement is to get the component fields(in extension) and i need to send those field values to some other API.
Can any one please help me with the Java code to get the component fields data.
You will not have access to the components fields in a deployer extension. What you work with is the published content which may be a page markup resulting from a CM side page template or a component presentation output for instance. You can enrich / modify the output before it is finally deployed to the file system or Content Delivery broker database. You can also use some of the output to export to another system during the deployment process. For instance deployer extensions are used to invalidate cache or update a search engine index.
Accessing the component fields on the Content Delivery side is usually done in your webapp itself, with the end goal of displaying the component fields data onto a web page, using SDL Web's Content Delivery APIs to query that content. DXA or DD4T can help you with that by making the component data model available from your MVC views.
It would be nice to explain what you are trying to achieve in more details, so that we can confirm that a deployer extension is the right approach for your use case.
I need the component fields in the extension only (not in application). After that I have to send the component data to some other API.
Below is my sample java code. I am not sure how to get component fields (title, metadata and some fields).
