Using JT400, how do I download a PrintObjectTransformedInputStream pdf file to my desktop?

Question

I am writing a program in Java using JT400. The program downloads certain spool files from AS400 to the client machine.

The process is roughly thus:

1. Connect
2. Access specific user's spool files
3. Loop through files until specific spool file found
4. Download that spool file to a local folder
5. Disconnect

My current problem is that I don't know how to download the file to local directory.

I have a PrintObjectTransformedInputStream pdf file, but I don't know how to work with that.

Code below:

static void hrzn(List<String> strUser, // Users to search for
                     List<String> lisReports, // List of reports to search and download for the user
                     int ipYear, // Year parameter
                     int ipMonth, // Month parameter
                     int ipDay, // Day parameter
                     String strPath // Path where spool file will be downloaded to
    ) throws AS400SecurityException, RequestNotSupportedException, IOException, InterruptedException, ErrorCompletingRequestException, ObjectDoesNotExistException, OpenListException {
        // Sign in to AS400
        String strUserLogin = "*******************************";
        String strPass = "***************************";

        AS400 hrznAS400 = new AS400("*************", strUserLogin, strPass);
        //User hrznUser = new User(hrznAS400, strUser);

        System.out.println(strUser.size());

        // Iterate through each user in the user list
        for (int i = 0; i < strUser.size(); i++) {

            System.out.println("User: " + strUser.get(i));

            // Create SpooledFileOpenList of the output queue of the user
            SpooledFileOpenList list = new SpooledFileOpenList(hrznAS400);
            // Filter spool file list to specific user
            list.setFilterUsers(new String[]{strUser.get(i)});
            // Sort by date create. False means descending order;
            list.addSortField(SpooledFileOpenList.DATE_OPENED, false);
            // Get the filtered list of spool files
            list.open();
            Enumeration enumFiles = list.getItems();

            // Loop through each of the spool files in the users output queue
            while (enumFiles.hasMoreElements()) {
                SpooledFileListItem item = (SpooledFileListItem) enumFiles.nextElement();

                System.out.println("User ID: " + String.valueOf(strUser) + " File: " + item.getUserData() + " File Creation Date: " + item.getCreationDate());

                // If the current spool file type is desired, execute code
                if (lisReports.contains(item.getUserData().trim())) {
                    System.out.println("File: " + item.getUserData() + " Date Created: " + item.getCreationDate());
                    // Create a spooled file
                    SpooledFile splF = new SpooledFile(
                            hrznAS400, // AS400
                            item.getName(), // SPLF NAME
                            item.getNumber(), // SPFL NUMBER

                    ); // https://javadoc.io/static/net.sf.jt400/jt400/11.0/com/ibm/as400/access/SpooledFile.html

                    // Get printer device type
                    String strPrType = splF.getStringAttribute(PrintObject.ATTR_PRTDEVTYPE);

                    // Extract date/time info from item fields
                    LocalDateTime localDate = LocalDateTime.from(item.getCreationDate().toInstant().atZone(ZoneId.systemDefault()).toLocalDateTime());
                    int year = localDate.getYear();
                    int month = localDate.getMonthValue();
                    int day = localDate.getDayOfMonth();

                    int second = localDate.getSecond();

                    // If the printer device type equals *SCS, proceed with PDF transform
                    if (strPrType.equals("*SCS")) {
                        System.out.println("Created instance of spool file");

                        // Set up print parameter list
                        PrintParameterList printParms = new PrintParameterList();
                        printParms.setParameter(PrintObject.ATTR_WORKSTATION_CUST_OBJECT, "/QSYS.LIB/QCTXPDF.WSCST"); // https://javadoc.io/static/net.sf.jt400/jt400/11.0/com/ibm/as400/access/doc-files/PrintAttributes.html#HDRKEYIFS_8

                        printParms.setParameter(PrintObject.ATTR_DEVTYPE, "*AFPDS");

                        // Create a transformed input stream from the spooled file
                        PrintObjectTransformedInputStream is = splF.getTransformedInputStream(printParms); //https://www.ibm.com/docs/en/i/7.4?topic=considerations-workstation-customizing-object-wscst-parameter

                        System.out.println("Transformed spool file to PDF");
