Getting the document content in a variable??

Question

Hi,
How can I get the entire contents of a document into a string variable? I donot
want to print the contents inline but rather have to get them in a variable. Using
printDoc or printProperty tag?? I guess I will have to use printDoc but then how
can I stop the contents from being displayed in the jsp and how can I put them
in a variable??
Please help me...
Thanx.

You should always double-check code put on the newsgroups, even if it's
put there by me :)
It probably should be at the beginning:
<es:forEachInArray array="<%=docs%>" id="adoc"
type="com.bea.p13n.content.document.Document">
<%
     byte[] bytes = adoc.getContentBlock(0L, -1L);
Notice 'byte[]' instead of 'bytes[]', the type specified as Document
(Content doesn't have the getContentBlock() method, the sub-interface
Document does), and the 'L's on the numbers to specify that they are
longs to help the compiler find the correct method.

Hi,
Thanx for your propmt reply. My code looks somethinglike this
<es:forEachInArray array="<%=docs%>" id="adoc" type="com.bea.p13n.content.Content"
          <%
          bytes[] bytes = adoc.getContentBlock(0, -1); // retrieve all the content
          String enc = adoc.getPropertyAsString(null, "encoding");
          String str = null;
          if (enc != null)
               str = new String(bytes, 0, bytes.length, enc);
          else // use VM default encoding
               str = new String(bytes);
          %>
          <li>The document title is: <cm:printProperty id="adoc" name="Title" encode="html"
/>
     </es:forEachInArray>
But it is giving me these two errors...

Could you plz specify if I have to include some file or something ?
Thanx.

You will need to call the getContentBlock() method on the Document
object to retrieve the bytes of the document's content. Then, you do
whatever you need to with the bytes. When converting it to a String,
you
should be aware of double-byte-character encodings, and should check
the
Document's encoding metadata attribute, e.g.:
<%
bytes[] bytes = doc.getContentBlock(0, -1); // retrieve all the content
String enc = doc.getPropertyAsString(null, "encoding");
String str = null;
if (enc != null)
str = new String(bytes, 0, bytes.length, enc);
else // use VM default encoding
str = new String(bytes);
%>
In 8.1, the new <cm:getProperty> is able to retrieve the BinaryValue
of
a binary property of a Node.
