How to Resolve 'No injection source found' Error in Jersey Multipart Form Data Upload?

Multipart Form Data Injection Issue

Issue Description:

When attempting to upload files through a REST service using Jersey, the following error is encountered:

No injection source found for a parameter of type public javax.ws.rs.core.Response

Problem Analysis:

The error indicates that the Jersey multipart form data feature is not properly configured or the required JAR files are missing.

Solution:

1. Remove and Add Required JAR Files:

• Remove the jersey-multipart-1.18.jar file, which is not compatible with Jersey 2.x.

• Add the following two dependencies:

  • jersey-media-multipart-2.17
  • mimepull-1.9.3 (dependency pulled in by jersey-media-multipart)

2. Register MultiPartFeature:

• Register the MultiPartFeature in your Jersey configuration:

  • ResourceConfig: register(MultiPartFeature.class);

  • web.xml:

    <init-param>
        <param-name>jersey.config.server.provider.classnames</param-name>
        <param-value>org.glassfish.jersey.media.multipart.MultiPartFeature</param-value>
    </init-param>

3. Update Imported Classes:

• After removing jersey-multipart-1.18.jar, there will be compile errors for missing imported classes. Update the class names to reflect the following changes:

  • org.glassfish.jersey.media.multipart.FormDataParam
  • org.glassfish.jersey.media.multipart.FormDataContentDisposition
