. A JNLP file is an XML-based configuration file used to launch Java applications over the web, while a PDF is a document format for viewing and sharing content. Depending on whether you want to save the inside the JNLP file or the convert jnlp to pdf

Her first instinct was brute force. She tried to run the JNLP with OpenWebStart, an open-source resurrection of Java Web Start. It failed. The old JARs had dependencies on Sun's proprietary imaging libraries that no longer existed. She tried to decompile the actuarial-core.jar using JD-GUI. The code looked like it had been written by a traumatized Perl programmer in 2005: Vector v = new Vector(); Enumeration e = v.elements(); No comments. Method names like doTheThing() .

The Python script did the rest:

She changed her strategy. Instead of running the application, she would trace its data flow. She used Wireshark to monitor the legacy-box's network traffic. When she manually triggered the old cron job script (a horrifying batch file with GOTO statements), she saw it: a POST request to http://legacy-box:8080/actuarial/soap/LossRunService with a SOAP envelope containing a date range. The response was a massive XML blob—actuarial data, policy numbers, claim amounts, loss ratios. Depending on whether you want to save the

She wrote a Python script. Not because Python was the best tool, but because it was the most forgiving. She used subprocess to call a small Java CLI tool she wrote in twenty minutes. That Java tool did only one thing: loaded the old JARs (including iText 2.1.7 and the Xerces XML parser) into a custom classloader, instantiated the PDFBuilder class via reflection, and exposed a simple method: byte[] generatePdf(String xmlData) .
