本文提供了一个使用Java和iText库生成简单PDF文件的示例代码。通过此代码，可以创建包含文本“HelloWorldcc”的PDF文档，并将其作为附件发送到客户端。

import java.io.ByteArrayOutputStream;
import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.Paragraph;
import com.itextpdf.text.pdf.PdfWriter;
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

Document doc = new Document();
ByteArrayOutputStream ba = new ByteArrayOutputStream();
try {
PdfWriter writer = PdfWriter.getInstance(doc, ba);
doc.open();
doc.add(new Paragraph("Hello World cc"));

} catch (DocumentException e) {
e.printStackTrace();
}
doc.close();
response.addHeader("Content-Disposition","attachment;filename=" + "test.pdf");
response.setContentType("application/pdf");
response.setContentLength(ba.size());
ServletOutputStream out = response.getOutputStream();
ba.writeTo(out);
out.flush();
