No editing - you compile the .java file which results in a .class file. The IDE does that for you, but it's possible it doesn't put the class files where they need to be. But after compilation they should be somewhere in the project folder, provided there were no errors.

A source file does no good in WEB-INF/classes - that's were the class file needs to be.

WEB-INF / classes / WebCart / WebCartServlet.java


Two problems:

1) The package name is "webcart", not "WebCart".

2) That's where WebCartServlet.class should be, not WebCartServlet.java.

I think you can replace all that by

return ImageIO.read(new ByteArrayInputStream(bytes));

Well, "src" is clearly a source directory, is it not?

Regardless, the class file needs to be inside WEB-INF/classes/webcart; is that where it is? Or is it in a jar file that contains all your classes? If so, that would go into WEB-INF/lib

Start by defining what the output should be. PDF and XLS are very different file formats, which lead to very different ways you can use them. Do you want something to print? Then PDF would seem to the medium of choice. Do you want something to edit? That would rule out PDF.

do you perhaps know why it is saying transfer-encoding chunked?


Because that's the transfer-encoding it's using - it's got to use something.

I think it is affecting the client side when I try to consume it using AJAX call, it goes in an error status.


What's the evidence that it's related to the transfer-encoding? What's the error message? What is what code doing when that occurs?

Normally you'd just use the ImageIO.read method which handles all the file formats it is capable of handling, without you having to do anything especially.

If memory serves, ImageIO can handle JPG, PNG, GIF and BMP out of the box, and can be made to handle TIFF with a bit of extra effort.

I'm not sure I understand what exactly you're asking.

If the task is to modify Excel files programmatically then Apache POI is almost certainly the best tool available.

If the task is to create PDF files, then PDFBox or iText would be good choices. Note that iText versions 5 and newer most likely will require you to obtain a license, whereas iText 2 does not.

java.lang.ClassNotFoundException: webcart.WebCartServlet


In which directory is the WebCartServlet.class file?

What do you mean, "however"? Is there a problem with the response using that transfer-encoding?

Indeed, I think a library such as Unity would be way overkill for your purposes. In Android you could subclass an android.view.View and use a Canvas to do custom drawing (which includes putting text on the canvas if need be).

A simple example: https://stackoverflow.com/questions/16605428/custom-view-canvas-ondraw-doesnt-draw-anything/16606144#16606144

That looks like JSON, so the obvious approach would be to use one of the many available JSON libraries. https://github.com/stleary/JSON-java would be a good choice.

Edit: I added linebreaks to the JSON so that the page is formatted properly, and also took the liberty of removing much of the duplicated data.

Yes, deploying on your own phone is done via the adb tool that comes with the Android SDK. Somewhere in the Settings of your device you need to allow apps to be installed from outside of the Play Store, though.

Does that mean the problem is solved? You say "Please reply if sucees" which sounds as if you are expecting people to try something and report back with the solution, but it's not clear what people should try, nor is it likely (IMO) that people will do your work for you. If, OTOH, there was a clear problem description, that would help us help you.

I am delighted to get nice respnse though only after several days.Thanks


Do you imagine that using sarcasm will make it more likely that people will help you?
