//set summary height

int summary_w = width - leftMargin - rightMargin;

int summary_h = height-(topMargin + bottomMargin + t1_h + north_img_h + logo_img_h);

su_band.setAttribute(new Attribute("height",String.valueOf(summary_h)));

//set pageFooter height

int pf_h = t1_h+north_img_h+logo_img_h;

pf_band.setAttribute(new Attribute("height",String.valueOf(pf_h)));

//set p0 width and height

int m_img_width = (int)Math.round(summary_h * (mapHeight / mapWidth));

su_reportElement.setAttribute(new Attribute("height",String.valueOf(summary_h)));

}else{

su_reportElement.setAttribute(new Attribute("width",String.valueOf(summary_w)));

su_reportElement.setAttribute(new Attribute("height",String.valueOf(m_img_height)));

}

su_imageExpression.setContent(new CDATA("\""+imgUrl+"\""));

//set t1

int t1_x = summary_w - t1_w;

int t1_y = 0;

//set t4

t4_reportElement.setAttribute(new Attribute("x",String.valueOf(t4_x)));

t4_reportElement.setAttribute(new Attribute("y",String.valueOf(t3_y)));

t4_text.addContent(new CDATA("Schaal "+scale+"\r\nDatum "+date_str));

//set north_img

north_img_reportElement.setAttribute(new Attribute("y",String.valueOf(t2_y)));

File imgFile = new File(realPath+"\\upload\\"+dataSet+"\\mapSym\\"+imgname);

if(imgFile.exists()){

north_img_imageExpression.setContent(new CDATA("\""+cpath+"/upload/"+dataSet+"/mapSym/"+imgname+"\""));

}

//set logo_img imgname

int logo_img_y = t3_y + t3_h;

logo_img_reportElement.setAttribute(new Attribute("x",String.valueOf(t1_x)));

logo_img_reportElement.setAttribute(new Attribute("y",String.valueOf(logo_img_y)));

logo_img_imageExpression.setContent(new CDATA("\""+cpath+"/images/logo2.gif"+"\""));

}

6、printPreview.jsp代码

<body>

Document doc = (Document)request.getAttribute("document");

String dataSet = (String)request.getAttribute("dataSet");

FirstReportCompile frc = new FirstReportCompile();

byte[] bt = frc.generatePDF(dataSet,doc);

response.setContentType("application/pdf");

response.setContentLength(bt.length);

ServletOutputStream ouputStream = response.getOutputStream();

ouputStream.write(bt, 0, bt.length);

ouputStream.close();

out.clear();

out = pageContext.pushBody();

</body>

写的有点乱，主要就贴了些代码，方便我以后回头看吧.....
