Sorry to say that it is a bit more complex than I at first thought but still
really quite straightforward.
I have played around with a bit of code and come up with a solution that works
a little like this;
inputFile = new File("C:\\temp\\Test.doc");
fileInputStream = new FileInputStream(inputFile);
buffInputStream = new BufferedInputStream(fileInputStream);
HWPF Document document = new HWPFDocument(buffInputStream);
Range range = document.getRange();
int numParagraphs = range.numParagraphs();
for(int i = 0; i < numParagraphs; i++) {
Paragraph para = range.getParagraph(i);
String paraText = para.text();
for(String key : keys) {
paraText = swapPlaceholderForText(key,
replacementText.get(key), paraText);
}
para.replaceText(para.text(), paraText, 0);
}
The first four lines simply open the Word file and there are corresponding
lines in my program to save the file after processing.
Next, I recover a reference to the Range object that describes the complete
document and then ask that how many paragraphs there are. That value which is
stored in the int variable numParagraphs is then used to control the for loop
where the work is actually accomplished.
Before getting to that loop, I should mention that I have stored the
placeholders and associated replacement text in a HashMap which uses the
placeholder as a key. Next, I have recovered a reference to the List of keys
and stored that into a variable called keys.
So, in the for loop, I am recovering a reference to each Paragraph and storing
it in the variable called para. Next, I get the text from each paragraph in
turn and store it into a local String variable called paraText. Aftre that, I
am searching through this String for occurrences of the placeholders and
replacing each with the associated text - that bit occurs within the inner for
loop when a call is made to a local method I have called
swapPlaceholderForText(). Finally, I call the replaceText() method on the
Paragraph object.
The swapPlaceholderForText() method looks like this;
private String replaceText(String key, String value, String text) {
int index = 0;
while((index = text.indexOf(key)) >= 0) {
text = text.substring(0, index) + value + text.substring(index +
key.length());
}
return(text);
}
Let me know if there are any things you cannot understand or if you want the
complete program as I will need to tidy a few things up.

Hallo everyboby.
I have benn looking for the last days
in internet trying to find a solution for my problem, and I found nothing
that could help me...so I am asking you help...
The problem:
I store in oracle table field (BLOB)
a word document.This document is a template whose content is text and also
few fields that I'm trying to fill up at runtime using HWPFDocument...but
I don't find the way.
What I want to do is at field with name
"name" put e.g. "Myname", to address
put "MyAddress" and so on.....
Here few code lines and what it prints
Range r = wordDocument.getRange();
for (int x = 0; x < r.numSections(); x++){
Section s = r.getSection(x);
for (int y = 0; y < s.numParagraphs(); y++){
Paragraph p = s.getParagraph(y);
for (int z = 0; z <
p.numCharacterRuns(); z++){
CharacterRun run = p.getCharacterRun(z);
//character run text
String text = run.text();
System.out.println(text);
}
}
}
