kandi X-RAY | struts Summary

struts is a Java library typically used in Architecture, Model View Controller, Framework applications. struts has no bugs, it has build file available, it has a Permissive License and it has high support. However struts has 1 vulnerabilities. You can download it from GitHub.
Web applications differ from conventional websites in that web applications can create a dynamic response. Many websites deliver only static pages. A web application can interact with databases and business logic engines to customize a response. Web applications based on JavaServer Pages sometimes commingle database code, page design code, and control flow code. In practice, we find that unless these concerns are separated, larger applications become difficult to maintain. One way to separate concerns in a software application is to use a Model-View-Controller (MVC) architecture. The Model represents the business or database code, the View represents the page design code, and the Controller represents the navigational code. The Struts framework is designed to help developers create web applications that utilize an MVC architecture.

ANSWER

Answered 2022-Apr-10 at 19:47

You are missing web application context path in the URL.

ws://localhost:8080/[CONTEXT_NAME]/websocket

Sometimes context name and project name are the same.

EXAMPLE:

ws://localhost:8080/web_socket_struts2_test/websocket

Vulnerabilities

No vulnerabilities reported

Install struts

You can download it from GitHub.
You can use struts like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the struts component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .

Support

More information can be found on the homepage. Please read the Security Guide, and the JavaDocs can be browsed. Questions related to the usage of Apache Struts should be posted to the user mailing list.
