Examples for using jasper-reports API

Setting up the environment

• Here we use a sample PostgreSQL database and an instance for the report server, with security disabled
• Database is based on this project
• Sample reports are saved to ./reports, which is mounted to the report server
• The root directory can also be opened as a jasper studio workspace, and reports directory will be imported as a project.
  • So, you can open this repo in jasper studio to fiddle with sample reports if you want
  • The project will have a data-soruce for the local sample database called local-postgres, this is what all the reports use.
• To run the environment run

docker-compose up

• To stop the environment and clean up

docker-compose down --rmi local

Example 1: Simple PDF report

• A simple report that shows list of movies from the database
• Doesn't required any other resources: fonts, sub-reports, images, etc

curl -o movies.pdf http://localhost:8080/report/ex1/movies.pdf

Example 2: Report with simple resources

• Simple report but with custom fonts and static image

curl -o movies.pdf http://localhost:8080/report/ex2/movies.pdf

Example 3: A Report book with nested subreports

• A report book that have two parts, the previous movies report and a summary page.
• Note that in the case of sub-reports, .jasper files must be provided and referenced in the main report.
• Sub-reports .jrxml files are provided here for reference only.
• Jasper studio gives the feature to add sub-reports as .jrxml files, and compiles them on the spot. But this is not the normal case in applications, AFAIK, the library doesn't provide this out-of-the-box.
• The report server currently doesn't auto compile sub-reports .jrxml files.
• parameter JR_force-compile=true directs the server to compile sub-reports to generate .jasper files for them if needed.

curl -o movie_book.pdf http://localhost:8080/report/ex3/movie_book.pdf?JR_force-compile=true
