Hi,
I am trying to create a pdf doc with images. In order to do this, I
created two servlets:
1. First servlet (riskmap) generates the pdf and html documents.
2. Some imgaes for the pdf and html documents are coming from anothe
servlet (createjpg).
Riskmap servlet generates html and pdf pages separately. The html page is
able to get the images from createjpg servlet(with in <img src> tag I
defined the servlet URL).
For the pdf page in riskmap servlet, I have used getInstance call as
below:
Image iRiskNo = null;
iRiskNo =
com.lowagie.text.Image.getInstance("http://localhost:8080/createjpg/createjpg";);
When it runs the above statement, it gives the following error
SEVERE: -->> returning Frame NULL
SEVERE: BaseDialog: owner frame is a java.awt.Frame
In creatjpg servlet, the statements that generate the image are as
follows:
created a bufferedimage and ...
.......
JPEGEncodeParam eP =
JPEGCodec.getDefaultJPEGEncodeParam(bufferedImage);
eP.setQuality(1.0f, true);
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
encoder.encode(bufferedImage, eP);
I imported the following classes in createjpg servlet:
import java.awt.*;
import java.awt.geom.*;
import java.awt.image.*;
import java.awt.Color;
import java.awt.Font;
import java.io.*;
import java.io.IOException;
import com.sun.image.codec.jpeg.JPEGEncodeParam;
import com.sun.image.codec.jpeg.JPEGImageEncoder;
import javax.servlet.http.*;
import javax.servlet.*;
import com.sun.image.codec.jpeg.JPEGCodec;
As I mentioned above, the riskmap servlet (pdf objects) does not receive
images from createjpg servlet.
Can someone please let me know how I can troubleshoot/solve this problem?.
