org.apache.camel.ResolveEndpointFailedException throws when an endpoint is not resolved by URI. It can happen because of formatting, escaping characters of the keyword are not used properly.

Camel Route Definition for SMTP Email

Here is the configured Camel route definition for SMTP email. Which is written as from one Gmail account to another email like to, CC and BCC.


String recipients = "&To=camel123@riders.org,easy123@riders.org&CC=me@you.org&BCC=someone@somewhere.org";
from("direct:a").to("smtps://smtp.gmail.com:465?username=job4saurabh@gmail.com&password=XYZ@123" + recipients);

Exception Stacktrace

As the exception cause described it’s because of unknown parameters CC and BCC. As for Camel Route Definition recognized all keywords in small letters.

Exception Reason

Apache Camel through this exception because of endpoint for URI is not resolved because of case-sensitive keywords. As here we are using BCC and CC as in capital letters while Apache camel allowed all keywords in small letters only.

Solution

Use keyword BCC and CC in small letters as defined in below camel route definition.


String recipients = "&To=camel123@riders.org,easy123@riders.org&cc=me@you.org&bcc=someone@somewhere.org";
from("direct:a").to("smtps://smtp.gmail.com:465?username=job4saurabh@gmail.com&password=XYZ@123" + recipients);
