The matching wildcard is strict, but no declaration can be found for element 'jaxrs:client'.



The Answer is in the Migration Guide

3.0 Migration Guide

JAX-RS

  • JAX-RS 2.0 has been completely implemented.
  • JAX-RS WADL auto-generation code has been moved to a new cxf-rt-rs-service-description module.
  • JAX-RS 2.0 Client API and CXF specific WebClient and Proxy client code is now available in a new cxf-rt-rs-client module. Important: the namespace for jaxrs:client elements has changed from "http://cxf.apache.org/jaxrs" to "http://cxf.apache.org/jaxrs-client"
  • CXF RequestHandler and ResponseHandler filters have been removed, please use JAX-RS 2.0 ContainerRequestFilter and ContainerResponseFilter and also WriterInterceptor and ReaderInterceptor when needed.
  • CXF JAX-RS Form extension has been dropped, please use JAX-RS 2.0 Form.
  • CXF JAX-RS ParameterHandler has been dropped, please use JAX-RS 2.0 ParamConverterProvider.
  • javax.annotation.Resource annotation can no longer be used to annotate JAX-RS context properties. Only javax.ws.rs.core.Context annotation is supported from now on.

Field or property 'jobParameters' cannot be found on object of type 'org.springframework.beans.factory.config.BeanExpressionContext' - Spring Batch

This Error happens when you are trying to retrieve a Job Execution parameter and inject it into a Bean. The bean can be anything a Task let, or a StatmentSetter the error can happen. E.g Implementation <bean id = "flatFileItemReader" scope="step" class="org.springframework.batch.item.file.FlatFileItemReader"> <property name = "resource" value = "#{jobParameters[input.file.name]}" /> </bean> The error is because of the Scope parameter missing Using a scope of  Step  is required in order to use late binding since the bean cannot actually be instantiated until the  Step  starts, which allows the attributes to be found. Because it is not part of the Spring container by default, the scope must be added explicitly. Check out the Documentation here ..  http://docs.spring.io/spring-batch/reference/html/configureStep.html#step-scope

java.security.spec.InvalidKeySpecException: Only RSAPrivate(Crt)KeySpec and PKCS8EncodedKeySpec supported for RSA private keys

public PrivateKey getPrivateKey(String fileName) throws IOException, InvalidKeySpecException, NoSuchAlgorithmException { byte[] keyFileBytes = readKeyFile(fileName); X509EncodedKeySpec spec = new X509EncodedKeySpec(keyFileBytes); KeyFactory kf = KeyFactory.getInstance("RSA"); return kf.generatePrivate(spec); } The reason is this line, This is used to read public key spec and not private key. The private key is read via PKCS8EncodedKeySpec spec = new PKCS8EncodedKeySpec ( keyBytes ); So as the error says it needs to be in PKCS8 spec format for java to understand.
