IBM MobileFirst - NoClassDefFoundError

Question

IBM MobileFirst Platform Studio (이전 IBM Worklight)를 사용하여 하이브리드 애플리케이션을 개발 중입니다.

OUT 매개 변수가 포함 된 Oracle 저장 PL/SQL 프로 시저를 호출해야한다는 요구 사항 때문에 여기서 제공된 How to get OUT parameter when invoking a stored procedure? 솔루션을 사용합니다. Java에서 저장 프로 시저를 호출하고 어댑터 프로 시저에서 Java 클래스를 호출합니다.

내 프로젝트의 server/java 폴더에 StoredProcedure.java src 파일을 추가했습니다. 나는 또한 commons-dbutils-1.6.jar와 ojdbc6.jar을 server/lib 폴더에 추가했다. StoredProcedure 클래스는 MobileFirst 개발 서버에서 저장 및 배포되도록 구축되었습니다. 또한 server.xml에 필요한 datasource를 정의했지만 구현 한 어댑터 프로 시저 (R-click on adapter -> Deploy MobileFirstAdapter, R-Click 어댑터 실행 -> MobileFirst 프로 시저 호출)를 테스트하려고하면이 오류가 발생합니다. 메시지 :

나는 그래서 백엔드 서비스가 평민 - dbutils-1.6.jar를 발견해야 할 다른 무엇

Eclipse 버전을 실행 중입니다 : Windows 7 64bit에서 64bit Java v1.7.0.72를 사용하는 Luna Service Release 1 (4.4.1), Oracle Server 11g에 연결.

Answer 1

server/lib 디렉토리에 필요한 jar를 삭제하면 제대로 작동하지 않습니다. 내가 필요한 항아리 (dbutils)과 server.xml에 다음과 같은 변수에 매핑되는 WorklightServerConfig

<workspace>/WorklightServerConfig/shared/resources 

에 Eclipse 작업 공간 상대적으로 다음 디렉토리에 저장된 프로 시저를 호출하기 위해 만든 사용자 지정 항아리를 복사해야

${shared.resource.dir} 

다음 오라클 lib 디렉토리를 정의, 나는 오라클라는 이름의 하위 디렉토리에 ojdbc6.jar

<library id="ORACLE_LIB"> 
    <fileset dir="${shared.resource.dir}/oracle" includes="*.jar"/> 
</library> 

<connectionManager id="OraclePool" maxPoolSize="40" minPoolSize="10"/> 

<dataSource id="mobileDatasource" jndiName="jdbc/mobile__datasource"> 
    <jdbcDriver libraryRef="ORACLE_LIB"/> 
    <properties.oracle URL="jdbc:oracle:thin:@..." password="..." user="..."/> 
</dataSource>
