RE: Image rendering components
Hi, Actually if it just contained the 'src' tag it would tie the presentation tier to the graph engine. Am I right ? If we use DTO's and the report images are dynamically generated then we are thinking of passing them from tier to tier ? What if the graph engine were in a machine different than that of the presentation tier ? Any ideas ? bye, Mohan -Original Message- From: Andrew Hill [mailto:[EMAIL PROTECTED]] Sent: Friday, October 11, 2002 11:25 AM To: Struts Users Mailing List Subject: RE: Image rendering components Hang on - you say " I have a StringBuffer of HTML that includes a generated image." - you dont mean that some is html text, and then theres a huge chunk of graphics data all in the same stringbuffer? - Surely the stringbuffer only contains the URL of the image as an attribute in an img tag right? -Original Message- From: Mohan Radhakrishnan [mailto:[EMAIL PROTECTED]] Sent: Friday, October 11, 2002 13:31 To: 'Struts Users Mailing List' Subject: RE: Image rendering components Hi, Could it be done with the help of tag libraries?

RE: Image rendering components
Hang on - you say " I have a StringBuffer of HTML that includes a generated
image." - you dont mean that some is html text, and then theres a huge chunk
of graphics data all in the same stringbuffer? - Surely the stringbuffer
only contains the URL of the image as an attribute in an img tag right?

Hi,
Could it be done with the help of tag libraries? My tag libraries
don't connect with the database directly. So I use DTO's. They contain the

Your action could write the html from your DTO directly to the response,
without the need to forward to a JSP.
this would go along the lines of:
inStream = docLib.getDataStream();
ByteArrayOutputStream out =new ByteArrayOutputStream();
byte[] buf = new byte[4096];
int i = -1;
while ((i = inStream.read(buf))!=-1){
out.write(buf,0,i);
}
response.setContentType(docLib.getContentType());
response.setIntHeader("Content-length",docLib.getSize().intValue());
response.setHeader("Content-disposition","attachment;filename="+docLib.getFi
lename());
ServletOutputStream sout = response.getOutputStream();
out.writeTo(sout);
out.flush();
out.close();
return null;
or something similar where you'd be writing the bytes of html string out.
