Java WebService upload download file code share _java

This example for you to share the Java WebService upload download file code for your reference, the specific content as follows

2. Release Test WebService (Eclipse Java EE IDE)

Right-click the class you just created, now webservice-->create webservice,webservice type Select bottom Upjava bean Web Service,service implementation Select the target class, the next step is to publish the Open method interface, until completed, Tomcat has started, right just generated WSDL folder inside the WSDL file, select Test WebService, enter the corresponding method parameters.

The above is the entire content of this article, I hope to help you learn, but also hope that we support the cloud habitat community.
