Protect Java Libraries and Desktop Applications

Use the New Project Wizard to create a PreEmptive Protection™ DashO™ project for a Java library or desktop application. The wizard examines your application and determines appropriate protection settings.

Prerequisites

Integrate Into a Library or Desk Application Project

To create a project for a Java library or a desktop application using the Project Wizard, do the following:

  1. Start DashO.
  2. Select File > Project Wizard.
  3. Select Library or Desktop App and then Next.
  4. Enter the location of your .jar file (or library directory) and the location of the JDK that DashO uses to resolve Java runtime classes.
  5. Select Next and review the dependencies the wizard finds. The wizard lists the dependencies your code needs at runtime or for obfuscation.
    • Add more .jar files as inputs to obfuscate or as runtime support libraries.
    • Add Java modules (.jmod) to the support libraries list.
    • Check the Missing classes list for classes your code references that the wizard can't locate.

  6. Select at least one entry point for DashO to follow and select Next. DashO uses entry points to find unused items and removes them from the obfuscated output.

    Note: If the jar's manifest includes a Main-Class attribute, DashO lists it as an entry point.

  7. Review the suggested annotation-based entry point rules. Enable a rule only if you're familiar with the annotation and want to preserve the code elements it decorates.

  8. (Optional) Select the Generate Entry Point rules based on Hibernate annotations checkbox to set the following rules:

    Applies To Rule
    Classes annotated with javax.persistence.Entity DashO doesn't rename or remove the class.
    Members of classes annotated with javax.persistence.Entity or javax.persistence.Embedded

    DashO doesn't remove:

    • Fields
    • Getters (0-parameter methods with names that begin with get or is)
    • Setters (1-parameter methods with names that begin with set)
  9. Select Next and indicate where to save the resulting project file.

  10. Select Finish.

If a project file with the same name already exists, DashO asks whether you want to replace it. If you replace the existing project, DashO saves the new settings and creates a backup of the previous project.
