Getting Exception while calling MimeUtility.encodeText(inputText, "UTF-8", null);

[dilumonjames93]

Describe the bug Getting below Exception while calling MimeUtility.encodeText(inputText, "UTF-8", null); with Japanese alphabets

English words are working fine.

Exception in thread "main" java.lang.IllegalStateException: Not provider of jakarta.mail.util.StreamProvider was found at jakarta.mail.util.FactoryFinder.find(FactoryFinder.java:64) at jakarta.mail.util.StreamProvider.provider(StreamProvider.java:177) at jakarta.mail.internet.MimeUtility.doEncode(MimeUtility.java:824) at jakarta.mail.internet.MimeUtility.encodeWord(MimeUtility.java:750) at jakarta.mail.internet.MimeUtility.encodeText(MimeUtility.java:527)

To Reproduce Steps to reproduce the behavior:

1. Create a sample Java class as below

import jakarta.mail.internet.MimeUtility; import java.io.UnsupportedEncodingException;

public class MimeUtilityExample { public static void main(String[] args) { String inputText = "人件費予算売上ﾘｷｬｯﾌ"; // Replace with your text try { String encodedText = MimeUtility.encodeText(inputText, "UTF-8", null); System.out.println("Encoded Text: " + encodedText); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } } }

2. add jakarta.mail-api-2.1.2.jar dependancy to the class
3. just run it
4. See error

Expected behavior it should encode the string successfully

2. add jakarta.mail-api-2.1.2.jar dependancy to the class

There are 4 jars that have to be added: angus-activation-XXX.jar,
angus-mail-XXX.jar jakarta.mail-api-XXX.jar jakarta.activation-api-XXX.jar

Not provider of jakarta.mail.util.StreamProvider was found is due to only adding the API and not the implementation.

@jmehrens is right - as of 2.1.2, the implementation is not part of the API jar, one has to explicitly which implementation to use, one example can be Angus Mail, which is the follower of the JavaMail/JakartaMail implementation
