Chapter 3. Review the Reports
The report examples shown in the following sections are a result of analyzing the com.acme
and org.apache
packages in the jee-example-app-1.0.0.ear example application, which is located in the Windup GitHub source repository. The report was generated using the following command.
WINDUP_HOME/bin/windup --input /home/username/windup-source/test-files/jee-example-app-1.0.0.ear/ --output /home/username/windup-reports/jee-example-app-1.0.0.ear-report --target eap:6 --packages com.acme org.apache
Use a browser to open the index.html
file located in the report output directory. This opens a landing page that lists the applications that were processed. Each row contains a high-level overview of the story points, number of incidents, and technologies encountered in that application.
Figure 3.1. Application List
The incidents and estimated story points change as new rules are added to Windup. The values here may not match what you see when you test this application.
Click on the name of the application, jee-example-app-1.0.0.ear, to view the application report. The following table lists all of the reports that can be access from this main Windup landing page.
Report | How to Access the Report |
---|---|
Click on the name of the application. | |
Click on the Archives shared by multiple applications link. Note that this link is only available when there are shared archives across multiple applications. | |
Click on the Executed rules overview link at the bottom of the page. | |
Click on the Windup FreeMarker methods link at the bottom of the page. | |
Click on the Send feedback link at the bottom of the page to open a form that allows you to submit feedback to the Windup team. |
Note that if an application shares archives with other analyzed applications, you will see a breakdown of how many story points are from shared archives and how many are unique to this application.
Figure 3.2. Shared Archives
Information about the archives that are shared among applications can be found in the Archives Shared by Multiple Applications reports.

The application report page gives an overview of the entire application migration effort. It summarizes:
- The incidents and story points by category (mandatory, optional, or potential issues)
- The incidents and story points by level of effort of the suggested changes
- The incidents by package

3.1.2. Application Details Report
Access this report from the report index by clicking the Application Details link.
The report lists the story points, the Java incidents by package, and a count of the occurrences of the technologies found in the application. Next is a display of application messages generated during the migration process. Finally, there is a breakdown of this information for each archive analyzed during the process.
Figure 3.4. Application Details Report
Expand the jee-example-app-1.0.0.ear/jee-example-services.jar
to review the story points, Java incidents by package, and a count of the occurrences of the technologies found in this archive. This summary begins with a total of the story points assigned to its migration, followed by a table detailing the changes required for each file in the archive. The report contains the following columns.
Column Name | Description |
---|---|
Name | The name of the file being analyzed. |
Technology | The type of file being analyzed, for example: Java Source, Decompiled Java File, Manifest, Properties, EJB XML, Spring XML, Web XML, Hibernate Cfg, Hibernate Mapping |
Issues | Warnings about areas of code that need review or changes. |
Story Points | Level of effort required to migrate the file. Story Points are covered in more detail in the Windup Rules Development Guide. |
Note that if an archive is duplicated several times in an application, it will be listed just once in the report and will be tagged with [Included Multiple Times]
.
Figure 3.5. Duplicate Archive in an Application
The story points for archives that are duplicated within an application will be counted only once in the total story point count for that application.
3.1.3. Source Report
The analysis of the jee-example-services.jar
lists the files in the JAR and the warnings and story points assigned to each one. Notice the com.acme.anvil.listener.AnvilWebLifecycleListener
file, at the time of this test, has 22 warnings and is assigned 16 story points. Click on the file link to see the detail.
- The Information section provides a summary of the story points and notes that the file was decompiled by Windup.
- This is followed by the file source code listing. Warnings appear in the file at the point where migration is required.
In this example, warnings appear at various import statements, declarations, and method calls. Each warning describes the issue and the action that should be taken.
