A simple example of using Java to read a Word file share _java

Java when reading Word documents, although many plug-ins on the web are introduced POI, Java2word, Jacob, Itext, and so on, POI unreadable format (the new API estimate line seems to be in the research and development phase, not too stable, do not dare to use the project); Java2word, Jacob Easy to complain can not find registration, more bizarre, I have tried in different machines, operation method is completely consistent, some machines do not complain, some errors, go to their forum to find an expert solution also said no reason, the project deployment with it a bit Hyun iTXt seems to be very convenient to write, but I have been looking for a long time the information has not seen a good way to read. After some choice or compromise point using RTF is the best, after all, RTF is open source format, do not need to use any plug-ins, just basic IO operation plus code conversion can be. Rich Text Format file on the surface and Doc does not make any difference, can be opened in Word, various formats can be set. The
 
-----Implements the ability to read rich-text template content (formatting and textual content), replace the change section, and form a new RTF document.
&NBSP
-----Implementation: The fixed part of the template is manually entered, the changed part is represented by $info$, just replace the $info$.
 
       1, Reading RTF template content in bytes
       2, Converts a variable content string to RTF
       3, replaces the variable part in the original text, and forms a new RTF document
 
Main program is as follows:
 

public string Bin2Hex (String bin) {char[] digital = "0123456789ABCDEF". ToCharArray ();
    StringBuffer sb = new StringBuffer ("");
    byte[] bs = Bin.getbytes ();
    int bit;
 
      for (int i = 0; i < bs.length;i++) {bit = (Bs[i] & 0x0f0) >> 4;
      Sb.append ("\ \");
      Sb.append (Digital[bit]);
      bit = Bs[i] & 0x0f;
    Sb.append (Digital[bit]);
  return sb.tostring ();
 public string Readbytertf (InputStream ins, string path) {string sourcecontent = "";
  try{ins = new FileInputStream (path);
     Byte[] B = new byte[1024];
     if (INS = null) {System.out.println ("source template file does not exist");
     int bytesread = 0; while (true) {bytesread = Ins.read (b, 0, 1024);//return final Read bytes counts if (bytesread = = 1) {//E
        nd of InputStream System.out.println ("Read template file End");
       Break } sourcecontent + = new String (b, 0, bytesread); Convert to string using bytes}}catch (Exception E) {e.printstacktrace ();
return sourcecontent;
 }
