JR PDF report into a WebSphere Portal Portlet

2003-03-19 06:54

WebSphere Portal comes with a PDF viewer which allows the user to view a PDF file either in a new window or withing the portlet itself.

 

The JSP uses an <EMBED> with src=existing file. The output is embeded with the PDF viewer into the html output.

 

How can I do the same thing with Jasper. I tried Outputstream (both JSP and Servlet), but I doesn't seem to work.

 

Some detailed help would be greatly appreciated.

Hi,

 

I'm not too familiar with the <EMBED> tag,

but if it already supports a "src" attribute that can

point to an URL containing a PDF file, then you

could specify there the URL of a servlet or a JSP

that delivers PDF content.

 

To see how to create a servlet or JSP that delivers

PDF content on-the-fly, you can check

the "webapp" sample.

 

I hope this helps.

Thanx Teodor..

 

Perhaps I should have elaborated a bit on my problem..

 

I did go through the webapp example.. and I got it working as is.. but when I try to incorporate that into a portlet environment.. things don't seem to work.. I think the portlet doesn't like the OutputStream way of doing things..

 

I also tried doing the following:

 

(1) Portlet calls its (2) own JSP which has the (3) Pdf JSP embedded in it as below:

 

This code is in the portlet JSP

=====================

 

<OBJECT CLASSID="clsid:CA8A9780-280D-11CF-A24D-444553540000"

WIDTH=450 HEIGHT=450>

<PARAM NAME="SRC"

VALUE='<portletAPI:encodeURI path='pdf.jsp'/>'>

<EMBED SRC=<portletAPI:encodeURI path='pdf.jsp'/>'

HEIGHT=450 WIDTH=450>

<NOEMBED>Your browser does not support embedded PDF files.</NOEMBED>

</EMBED>

</OBJECT>

 

 

this works smoothly.. I get the report into my portlet very nicely.. but then I faced the problem of passing info to it.. e.g., portlet configuration information relating to the database such as user_id.. passowrd.. etc..

 

I'm not sure if there's any other way of getting the ODF output without having to write to a file and at the same time not using the output stream..

 

This is a unique issue I'm facing with the portlet environment.. I hope someone out there with experience in this area can provide some feedback..
