The second message in the stack is
Caused by: java.lang.NoClassDefFoundError: org/apache/commons/lang/StringUtils
which means you're missing commons-lang-*.jar (where * is a version number). I just checked my Eclipse installation and there is no official JAR in my plugins folder. I've found it inside of a couple of plugins (in the lib/ folder) where it's hidden from other plugins.
Try this:
Go to http://download.eclipse.org/tools/orbit/downloads/ and find the latest build ("drop")
On the info page for the latest build, search for commons.lang
In my case, the last version of org.apache.commons.lang is 2.6.0.
Note: org.apache.commons.lang3 isn't compatible!!
Download the JAR
Put it into the folder dropins/
Restart Eclipse
If that doesn't work, reinstall the JBehave plugin.

How to declare variable in MethodDeclaration block

I want to create a statement in MethodDeclaration block like this
SystemConfig config =new SystemConfig();
Below is the code I am trying but getting error "java.lang.IllegalArgumentException" .
VariableDeclarationFragment newDeclFrag= ast.newVariableDeclarationFragment();
newDeclFrag.setName(ast.newSimpleName("config"));
ClassInstanceCreation systemClass = ast.newClassInstanceCreation();
critterClass.setType(ast.newSimpleType(ast.newSimpleName("SystemConfig")));
newDeclFrag.setInitializer(systemClass);
System.out.println("variable dec =********** "+newDeclFrag.toString());
VariableDeclarationStatement statementConfig = ast.newVariableDeclarationStatement(newDeclFrag);
block.statements().add(statementConfig);
Can anyone help, how to declare variable in method declaration block.
Output-
variable dec =********** config=new SystemConfig()

The correct way to define "SystemConfig config =new SystemConfig();" is:
define VariableDeclarationStatement with
define a type as SimpleType
define a name as SimpleName

Getting Exception When Using OAuth in Web Service

I have a webservice which was developed to manage our In-App-Billing. Now I want to change it to include support for Android Subscription API. So I've to use the OAuth to query Google's server.
My code works perfectly as a console based application. However when I try to publish it as webservice I get below exception. Is it some kind of bug or am I doing something wrong? Please guide me if I am wrong.

I have put bcel-1.3.2.jar in the build path also. Still it is giving me the same exception.
The same code is working fine as a stand alone java application.But not working in a SWT plugin project.

You need this jar in your classpath at runtime.

Cannot open XML files on Eclipse

I've got a problem with the basic HelloWorld program. I didn't change the basic program. But, when I want to open any *.xml file in the res/values folder an exception appears:
An error has occurred. See error log for more details.
java.lang.NullPointerException
And here is the exception stack trace:

I don't know what I have to do.

It looks like you haven't set up Eclipse correctly. Did you follow the instructions at:-
