CONVERT_OTF_2_PDF output can be shown on the web using java sevlet

[Former Member]

Hello, all,

I used FM CONVERT_OTF_2_PDF, and I can create a pdf file on my PC by using content in table lines of FM. Now I don't want to create a pdf file on my desktop. I want to pass the value of the table lines to remote java program to show this PDF file on the web. Does anyone knows how do I code it in Java program to be able to show the contents in table lines as PDF? Would you please give an example code? Thank you!

Hi Meiying,

If your client side program is a web application (jsp,etc), you can pass the generated pdf file to the client side and display it with Acrobat reader (preinstalled) automatically.

wish it helps.

If you can not display the pdf file in a web page, for instance, you want to display it in applet, iText may help you to build a pdf viewer. iText is an open source project. You still can check out JPedal which is a pdf viewer to integrate it into your application.

Hi, Dennis,

Thank you for the reply. But I don't want to generate pdf file and then pass it to client side, beacuse there maybe serveral people runing the program at the same time. I want to pass the table which contains the content of PDF file (the data start with %PDF-) to java program as parameter. But I don't know how to write java code to show it ( I mean pdf content not pdf file) on the web.

If you want to display the content of PDF in BINARY, ignore my comments. For instance, the following stuffs.

%PDF-1.4

Otherwise,

Since all the contents of the pdf file are already in table, you can get or convert them into a array of bytes (Binary). Open a stream to the client side and pass the bytes to the client side then resemble them into a pdf file (maybe just in memory or put it in a temporary location), the ways I talked about in my above posts are the solutions you can use to display the pdf file.

Hi, Dennis,

The contents in the table look like following. (code)

There are two fields (TDFORMAT and TDLINE) in the table, I used following Java code to put them together as PDF. But When I open it as PDF file, it says "the file does not start with %PDF-' . Do you see why

(code)

byte[] pdfstream;

byte[] myout = new byte[]{};

byte[] tdformat = new byte[]{};

byte[] tdline = new byte[]{};

//String myout = "";

for (int i = 0; i < lt_pdftab.getNumRows() ; i++) {

JCO.FieldIterator e1 = lt_pdftab.fields();

while (e1.hasMoreElements()) {

JCO.Field field = e1.nextField();

lt_pdftab.setRow(i);

if (field.getName().equals("TDFORMAT")) {

tdformat = field.getString().getBytes("UTF-16LE");

}

if (field.getName().equals("TDLINE")) {

tdline = field.getString().getBytes("UTF-16LE");

}

myout = tdformat = tdline ;

}

System.out.println("myout " + myout );

pdfstream = myout;

}

(/code)

[Former Member]

Is TDLINE a long text field?

Try to change the following line:

field.getString().getBytes("UTF-16LE");

to:

InputStream input = field.getBinaryStream();

then get the bytes.

no. not very long. It only contains 132 chars. Thank you.
