Java web service framework 비교

	Support	Contract	비고
Apache AXIS2		first, last	가장 많이 사용(기준?) Spring framework 적용가능
Apache CXF	JAX-WS JAX-RS SAAJ Web Services Metadata for the Java Platform	first, last	가장 널리 사용되고 있는 추세 (AXIS2에서 CXF로 넘어오는 경우가 많음) AXIS2 보다 사용하기 편리 웹서비스 관련 표준들을 준수 (WSDL 2.0은 아직 지원하지 않음) 최소한의 오버해드로 웹서비스 관련 프레임웍 중 성능이 가장 뛰어남(?) Spring framework 적용가능 전자정부 표준 프레임워크에서 사용
Jersey	JAX-RS	?
Spring-WS	JAX-RS	first	JAX-WS 표준을 완벽히 지원하지 않음 JAX-WS 같은 Spring annotation 지원 개발자가 작성해야할 코드가 가장 작음
RESTEasy	JAX-RS JAXB	?	JBoss 프로젝트 Rich set of providers for: XML, JSON, YAML, Fastinfoset, Multipart, XOP, Atom, etc. JAXB marshalling into XML, JSON, Jackson, Fastinfoset, and Atom as well as wrappers for maps, arrays, lists, and sets of JAXB Objects. Gzip content-encoding 지원
Restlet	JAX-RS	?	경량 REST 프레임워크 Xstream, Jackson을 이용한 XML, JSON marshalling, unmarshalling 지원 FreeMarker, Velocity 통합가능 대용량 멀티파트 데이터 처리를 위해 Apache FileUpload와 통합가능
Spring @MVC		N/A	Spring MVC를 이용해서 RESTful 서비스를 구현 https://spring.io/guides/gs/rest-service/

* JAX-WS : Java API for XML-Based Web Services (JAX-WS) 2.0 – JSR-224

* JAX-RS : The Java API for RESTful Web Services – JSR-311

* SAAJ : SOAP with Attachments API for Java (SAAJ) – JSR-67

* JAXB : Java Architecture for XML Binding

Subversion 계정정보 삭제

* 환경
OS X 10.9.2
STS 3.4.0 (Based on Eclipse 4.3.1)
Subclipse 1.8.x

* Subclipse 설정에 따라 아래 두개 파일중 하나 삭제 (그냥 다 삭제해도 무방한듯..)
~/.eclipse_keyring
~/.subversion/auth

* 구글링 해보면 keyring 파일이 {EcliipseInstallDir}/configuration/org.eclipse.core.runtime/.keyring 라고 나오는데 환경에 따라 위의 사용자 홈 디렉토리에 있음
