如何在Java中將字符串轉換爲PDF

目前我正在使用此代碼，但其投擲PrintJobFlavorException。這是我的代碼幫我解決這個一個：如何在Java中將字符串轉換爲PDF

public class PJUtil { 
    public static void main(String[] args) throws Exception { 
     DocFlavor flavor = DocFlavor.INPUT_STREAM.PDF; 
     Writer output = null; 
     String text = "printing in pdfPrinting in Java "; 
     File file = new File("C:\\CMPSup_AL_.PDF"); 
     output = new BufferedWriter(new FileWriter(file)); 
     output.write(text); 
     output.close(); 
     InputStream is = new BufferedInputStream(new FileInputStream(file)); 
     PrintService service = PrintServiceLookup.lookupDefaultPrintService(); 
     DocPrintJob job = service.createPrintJob(); 
     Doc doc = new SimpleDoc(is, flavor, null); 
     PrintJobWatcher pjDone = new PrintJobWatcher(job); 
     job.print(doc, null); 
     pjDone.waitForDone(); 
     is.close(); 
    } 
}

和異常是

Exception in thread "main" sun.print.PrintJobFlavorException: invalid flavor 
    at sun.print.Win32PrintJob.print(Win32PrintJob.java:327) 
    at Collections.PrinterJobUtil.main(PrinterJobUtil.java:89)

是什麼讓你認爲該文本字符串是一個有效的PDF文檔？（提示，不是）。 – jtahlborn

你不能僅僅調用一個PDF文件，它需要是一個真正的PDF格式的文件。不知道這是什麼問題，但它肯定無濟於事。 –
