How to Solve 'No injection source found' Errors in Jersey Multipart File Uploads?

Multipart File Upload Issues with Jersey Restful API

In an effort to create a RESTful service for file uploads, you encountered the error: "No injection source found for a parameter of type public javax.ws.rs.core.Response." This error arises after attempting to run your Tomcat server.

Solution:

Your current dependencies include jersey-multipart-1.18.jar, which is meant for Jersey 1.x. For a successful build, replace it with these two JARs:

• jersey-media-multipart-2.17
• mimepull-1.9.3

Additionally, register the MultiPartFeature class to your application. If using ResourceConfig, simply invoke:

register(MultiPartFeature.class);

For web.xml configuration, add the following as an init-param to the Jersey servlet:

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

After removing jersey-multipart-1.18.jar, you may encounter compile errors due to modified package names. Specifically, the following package names have changed:

• FileUploadHandler -> org.glassfish.jersey.media.multipart
• MultiPartFeature -> org.glassfish.jersey.media.multipart
• FormDataParam -> org.glassfish.jersey.media.multipart
• FormDataContentDisposition -> org.glassfish.jersey.media.multipart

Update your code accordingly, and your file upload service should operate as intended.
