I'm trying to write a PDF, more specifically write as a HMTL page, using iTextPdf and XMLWorkerHelper, using verions 5.5.9 of both.
But when I try to write to the PDF I get an exception, NoSuchMethodError, no clue as to what is causing this.
java.lang.NoSuchMethodError: com.itextpdf.text.Paragraph.setRole(Lcom/itextpdf/text/pdf/PdfName;)V

Hoping someone can shed some light in this matter, thanks a bunch.
This almost always means that you compiled against one version of a library (in this case, iText) but you are deploying with a different version.
Check the versions in both environments and verify that they are both, in fact, 5.5.9

enter image description hereDoes anyone know, how to solve the import com.sun.prism.Graphics problem? It says to me, that the import is not accessible.- I coded this according to the tutorial... And Java also advices me to add this command. But when I add it, Java says that its not accessible.
(Basic game tutorial)
This is internal class of particular JRE implementation. It is not part of Java Language Soecification. The tutorial you are using is bad in this sense.
If you really want to implement graphics with Java, consider Java FX.

When I add wlfullclient-12.1.1 external jar into my external jar libraries my spring application breaks. When I remove the jar it works fine. How can I incorporate the jars without receiving an error?
many errors
It's embedding a different version of javax.validation, and there's a missing method that Spring, via Hibernate Validation, is trying to invoke.

I tried loading shape files using GeoTools.It is working fine.
But when i am trying to load the raster maps, i am getting some warning like
Can't load a service for category "GridFormatFactorySpi"Can any one throw some light on my issue?
The GridFormatFactorySpi interface is implemented by various formats; some examples are ArcGrid, GeoTIFF and GrassRaster.
It sounds like you need to include additional dependencies to be able to read your raster map. The three examples I cited above are GeoTools Plugins; there are others.
Without more information, such as, the type of raster you are trying to read, and the build tool (Maven, Ivy, Ant..) you are using to manage dependencies; there is little more that I can say to help you.

I have been following the official tutorials about Sockets (link to the tutorials); however, I have not been able to 'link' two PC's with two different operating systems, there are not errors shown.
I would like to know if it is possible to do this entirely on Java, or if there is any existent library out there that does it.
Thank you in advance.
Java should already by platform, OS and hardware independent. You may have network issues?

I followed Google's tutorial for the Java version of App Engine and when I ran it on my machine it would work fine at localhost:8888/guestbook and all it displayed was Hello, World. However when I deployed it and then accessed it through app-name.appspot.com/guestbook, it gives me a 500 error.
Here's the GuestbookServlet code: http://pastebin.com/LrAjXjW4
web.xml and appengine-web.xml contents: http://pastebin.com/UYFw3ChZ
I'm really sorry if this is a noob mistake and easily found by searching but I looked around for half a day and still couldn't find an answer.
I'll post more code if necessary but its basically the first tutorial of AppEngine in Java
Thanks
Sounds like you're using Java 7, which App Engine doesn't support. Recompile with JDK6 and it should clear up.
