Java Email ContentType tutorial with examples
This class represents a MIME Content-Type value. It provides methods to parse a Content-Type string into individual components and to generate a MIME style Content-Type string.
Example
The following code shows how to use ContentType from javax.mail.internet.

Java HttpHeaders CONTENT_TYPE
The field CONTENT_TYPE() from HttpHeaders is declared as:
public static final String CONTENT_TYPE = "Content-Type"; Example
The following code shows how to use HttpHeaders from javax.ws.rs.core.
Specifically, the code shows you how to use Java HttpHeaders.CONTENT_TYPE.
import javax.ws.rs.core.HttpHeaders; import javax.ws.rs.core.MediaType; import javax.ws.rs.core.Response; public abstract class BaseController < public static Response buildResponse(Object entity) < return Response.ok(entity).header(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON + "; charset=utf-8") .build(); > >
import javax.ws.rs.client.ClientRequestContext; import javax.ws.rs.client.ClientResponseContext; import javax.ws.rs.client.ClientResponseFilter; import javax.ws.rs.core.HttpHeaders; import javax.ws.rs.core.MediaType; import java.io.IOException; class FixHeadersClientResponseFilter implements ClientResponseFilter < @Override public void filter(ClientRequestContext requestContext, ClientResponseContext responseContext) throws IOException < responseContext.getHeaders().putSingle(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON); > >
import javax.ws.rs.WebApplicationException; import javax.ws.rs.core.HttpHeaders; import javax.ws.rs.core.MediaType; import javax.ws.rs.core.Response; /** * Open Tenure exception object */ public class OTRestException extends WebApplicationException < public OTRestException(int statusCode, String message) < super(Response.status(statusCode).entity(message) .header(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON + "; charset=UTF-8").build()); > >
