I'm not sure I understand what you mean. Are you asking how to continue
evaluating the JSP while the image is being generated? Easy. Create a
class like this:
public class ParallelImageGenerator
{
public ParallelImageGenerator() { ... }
public String getGeneratedFilename() { ... }
public void start() { ... }
public void wait() { ... }
}
Then, from your tagStart method in your custom tag library, do something
like this:
pig = new ParallelImageGenerator();
pig.start();
jspOut.print("<img src=\"" + pig.getGeneratedFilename() + "\" />");
// Register the 'pig' object somewhere so you can go back and "wait"
// on all of the image generators.
