What is a JWS file?
A JWS file is a workspace settings file used by Oracle JDeveloper, an integrated development environment ([IDE|ide]) for building Java and other enterprise applications. It stores information about a developer's workspace, including references to projects, window layout, panel positions, and other environment preferences. JDeveloper uses this file to restore the workspace state when reopening it, and teams may share JWS files to standardize workspace organization, although the file is often specific to an individual user's development setup.
More Information
JWS files are saved in an XML-based format, which allows the IDE to organize workspace data in a structured and readable way. Rather than storing source code, the file stores configuration and layout details that help manage how projects are displayed and accessed within the IDE. JDeveloper reads and updates the JWS file automatically as users open projects, rearrange panels, or change workspace settings.
How to open a JWS file
You can open JWS files with Oracle JDeveloper. When the application loads the files, it interprets their settings and opens the associated workspace.
Since the file is saved in XML format, you can also open it with a text editor to view its contents. However, manual editing is not recommended unless you are familiar with JDeveloper's workspace structure, as incorrect changes may prevent the workspace from loading correctly.

A JWS file may also be a Java source file used to implement web services on a web server. It contains plain text Java source code that defines how a web service behaves, including the methods that clients can call remotely. When deployed, the web server processes the JWS file and exposes its methods as web service operations that can be accessed over standard web protocols.
More Information
JWS files are commonly associated with Apache Axis–based web services, where the server automatically compiles the JWS file and generates the necessary service interfaces at runtime. JWS files often use Java annotations (introduced in JDK 5.0), such as @WebService, to describe service metadata, including method exposure, naming, and scope. This approach reduces the need for separate configuration files.
Java developers and enterprise application developers who build or maintain SOAP-based web services are most likely to use JWS files, which allow them to define service logic directly in Java, making them suitable for server-side applications where Java is already in use. They are most common in legacy or existing systems that rely on Axis-style web service deployment.
How to open a JWS file
You can open JWS files with any text editor or Java IDE, such as IntelliJ IDEA, [Eclipse|eclipse_foundation/eclipse], or [Apache NetBeans|apache/netbeans], since the file contains readable Java source code. To run or use the web service, the file must be deployed to a compatible Java web server or servlet container that supports JWS-based services, where it is compiled and executed as part of the server application.
