Displaying doc/txt file contents from portlet

Question

Hi, Can someone pls give a hint on how to do this:
One "book" type content created, with a doc file uploaded. The "publisher " for
this content is set to "sams".
create a content selector which retrieves only this (content) book correctly.
create two portlets. one portlet with above content selector inserted, displays
the publisher name with a hyperlink.
I want the other portlet to display the contents of the file uploaded, for this
publisher. I could establish portlet comm. and could display other properties
of the book such as "author/titile" on the second portlet, but want to know how
to display the uploaded file contents.
thanks much,

Answer 1

As far as retriving the contents of an uploaded file...
If your XML document has been loaded into Content Management as a binary
property, you have two options:
a) to directly inline the content into the JSP, do something like this:
<cm:getProperty id="node" name="binaryPropertyName" failOnError="true"
isMultiple="false"/>
(This assumes node holds a reference to the Content Management Node
object (perhaps retrieved via a <cm:getNode> tag)
b) to retrieve the value into a script variable for more processing, do
something like this:
<%
Property bodyProp= (Property)node.getProperty("binaryPropertyName");
InputStream in= node.getPropertyBytes( bodyProp.getId() );
// dont forget to close the InputStream
String result=null;
InputStreamReader reader= new InputStreamReader(in);
StringBuffer streamContents= new StringBuffer();
char[] data= new char[8192];
int charsRead;
while ((charsRead = reader.read(data)) > 0 )
streamContents.append(data, 0, charsRead);
result= streamContents.toString();
