Follow the instructions below to install DAS on Windows.

Note

Before you begin:

See the known incompatibilities section to find out if this version of the product has issues running on your OS due to the JDK version.
See the compatibility matrix to find out if this version of the product is fully tested on your operating system.

Installing the required applications

...

Make sure your system meets the Installation Prerequisites.
Info
Java Development Kit (JDK) is essential to run the product.

...

Installing the DAS

Download the latest version of the DAS as described in Downloading the Product.
Extract the archive file to a dedicated directory for the DAS, which will hereafter be referred to as <DAS_HOME>.

...

Set the properties from a script: Setting your system properties in the startup script is ideal, because it ensures that you set the properties every time you start the server. To avoid having to modify the script each time you upgrade, the best approach is to create your own startup script that wraps the WSO2 startup script and adds the properties you want to set, rather than editing the WSO2 startup script directly.
Set the properties from an external registry: If you want to access properties from an external registry, you could create Java code that reads the properties at runtime from that registry. Be sure to store sensitive data such as username and password to connect to the registry in a properties file instead of in the Java code and secure the properties file with the secure vault.

Info

Once all the instructions given above are completed, you may see the following error in the start up logs when you run the DAS server.
