Re: Need help with Can't create ICOFile: Can't read bytes: 4 while creating ClientBundle

I finally found the problem.

In my project I am using a third party library that uses some other third party library for reading ICO files. It was a class in this file that was throwing a NPE. I have no idea why that class was being referred anyway because I am not using ICO files at all. So I surgically remove those classes for the jar and it worked.

I couldn't figure out how to debug the compile part in Eclipse. So I converted the project to Maven format and loaded it up in Netbeans. But when I loaded it up there, the exception was not thrown at compile time. I was thrown at run time!

It was bad. I wasted all my weekend on this stupid problem.

Thank you for your reply, Jens.

Yes, I think I am putting the image in the same package/location where my clientbundle class is. Otherwise, Eclipse shows error.

Regarding ICO, you are right. I thought the same and so just to make sure I created a fresh gif and png and tried with those. But it shows the same message. I don't know why it says ICOFile in the message ("Can't create ICOFile: Can't read bytes: 1") but I am pretty sure that it is not an ico file. BTW, the number of bytes in the message seems random. I have seen it say Can't read bytes: 2 as well as ICOFile: Can't read bytes: 4.

Another thing is, when I use the same gif and png in style sheet, it works fine. i.e. when I set the following style for a label , it shows up fine:

.testStyle{

    background-image: url("rtick.gif");

    background-repeat: no-repeat;

    padding-left: 15px;

    border:none;

}

Of course, I had to put it in another location for the style, but it worked. So the image file itselfs seems to be ok.

Regarding breakpoint, that's a good suggestion but I am not sure how to do that because the error is coming at compile time itself!  I get the error when I do Google ->GWT Compile. Can you please tell me how to do the compilation in debug mode?

thank you.
