Restlet Version 2.2 java.lang.NoSuchMethodError: javax/xml/stream/XMLInputFactory.newFactory()

I am using the Restlet Version 2.2.0 with the IBM jdk 1.6.0_26 and I am trying to implement a REST Service. While executing my test project I am getting the following error:
Starting the internal [HTTP/1.1] server on port 8080

While using Sun/Oracle 1.6 JDK the problem doesn't exist, but I need to stay at
IBM jdk 1.6.0_26.
Any help would be appreciated.
Thanks,

It's likely a problem with the fallback JAXP selection between the two JDKs. Run java with -Djaxp.debug=1 and have a look at your logs. I'm currently encountering this same issue and my logs are showing
JAXP: find factoryId =javax.xml.parsers.SAXParserFactory
JAXP: loaded from fallback value: com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl
JAXP: created new instance of class com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl using ClassLoader: null
I'm pretty certain that my issue is OSGi related. Here's the link to another question with what could be a similar outcome: Unable to find a factory for http://www.w3.org/2001/XMLSchema

I have tried to downgrade from JAVA JDK 1.8 to 1.7 but still not resolving the problem.
This is a JavaScript project, the test are passing but build failed because of that error.
Could you help me?

We fixed it by reducing jenkins stdout/stderr output. Just redirect called commands' output to files and try again.
It is just a workaround until Jenkins team fix it but it works pretty well for us.

Unable to start server due following issues: Launch process failed with exit code 1

For 3 days now, I have been trying to install glassfish 4.1 on eclipse Luna version 4.4.1. I first installed the plugin from eclipse marketplace then added it in my runtime using jdk 8. I also made jdk my default since eclipse default uses jre. I have to point out that I have been been using glassfish on netbeans and tomcat on eclipse but I decided to play around with glassfish on eclipse. Every information I got on the internet didn't fix my issue.
Below is the error I got in the console. Right now, this is driving me nuts so I have decided to come to you for direction.
Thanks

Run Eclipse or any other IDE you use in Administrator mode.
Works for me.

I think your comment deserves to be posted as the main answer but I have been trying to mark your comment as answer but I wash't able to. So I decided to post post your comment here and then back it up with my own experience.
Answer by unwichtich:
I guess this is a similar problem. The cause may be that you have installed Glassfish in c:\Program Files. You can try to move your Glassfish installation to a directory where your normal user account has full access rights but you then have to change the path to the Glassfish installation in Eclipse.
My own experience:
Turns out that all the problems I had with the glassfish server (including exit code 1 error) was because glassfish could not handle folder names with spaces in it. So I moved the glassfish-4.1 folder from C:\Program File\glassfish-4.1.. path to C:\ glassfish-4.1.. It wiped all my tears away. This is really important in eclipse and netbeans IDEs (if you are installing the netbeans that does not come with a glassfish bundled zip).

I had the same problem and fixed it by installing Glassfish under C:\ instead of C:\Program Files. Try that.

use JDk 7 instead of JDK 8 am also faced the same issue i just changed to jdk7 its working now.

I have two versions of java, one is 1.8.0_25, the other is 1.7.0_46
this is my path
C:\Program Files (x86)\Java\jre7\bin;;C:\oraclexe\app\oracle\product\11.2.0\server\bin;;C:\ProgramData\Oracle\Java\javapath;
and as a default I use the jre7 on eclipse, dont know what else to mention here. I found no solutions clearly explained here or on the other websites rather than trying to change the java version, tried all java instances on my computer, uninstalled and installed again. I am guessing it may be about java and datanucleus compability issue, but currently using the java7 and the plugins i am using were downloaded automatically from eclipse so no clue. If you need any clarifications, ask me out please.

If you are using Java 8, you need to set the compiler compliance level to 1.7 in project properties. You will also need to change the java facet version

Note that (GoogleAppEngine Enhancer Error Code 1:)
App Engine doesn't work with Java 1.8. Try doing it again, with Java 1.7
Setting Java 1.7 in Project settings solves me the problem.

Well like I have guessed, it is all about the compatibility issue. If you are getting this error, make sure EVERYTHING your eclipse AND your computer use is the same version of java everywhere. What I mean is you need to check;
In eclipse, from the top menu choose Project->Properties, then make sure all the versions of java used by eclipse are the same.
AND
AND
and of course your environment variable should point to the same version that eclipse uses.
Hope this helps. Post comments if you found it unclear. Getting errors before even started coding sucks :p

Thanks for help.

This is a bug in this version of the database engine, which was fixed in revision 5437 of the trunk.
You can either:
go back to the previous version (1.3.174) which should not have this bug,
use the latest nightly build where it should be fixed,
download the latest source code and built the database yourself, or
wait for the next version of H2.
