It seems that there is no way how you can directly convert Java archives (.jar files) to Silverlight installation packages (.xap files). Some developers provide apps for multiple platforms, so just check if the Java app is also available for Windows Phone or in desktop version based on Silverlight.
Simply put, it is impossible to convert JAR to XAP directly.
Thus, there is no so-called jar to xap converter or a free online .jar to .xap conversion tool.

Understanding JAR and XAP file formats
JAR (Java ARchive) is a package file format typically used to aggregate many Java class files and associated metadata and resources into one file for distribution. It is commonly used for Java applications and libraries.
XAP is a file format used by Microsoft Silverlight applications. It is essentially a compressed archive that contains the application’s compiled output, including the .NET assemblies and resources needed to run the application.
Converting JAR to XAP
Converting a JAR file to an XAP file involves transforming a Java application into a Silverlight application, which is not a straightforward process due to the differences in the platforms. This typically requires rewriting the application code to be compatible with Silverlight.
Best software or converter for JAR to XAP conversion
There is no direct software or converter that can automatically convert a JAR file to an XAP file due to the fundamental differences between Java and Silverlight platforms. However, developers can manually rewrite the application using a development environment like Microsoft Visual Studio to create a Silverlight application.
To create a Silverlight application in Visual Studio, follow these steps:
- Open Microsoft Visual Studio.
- Go to File → New → Project.
- Select Silverlight Application from the project templates.
- Manually rewrite your Java application code in C# or VB.NET.
- Build the project to generate the XAP file.
