jdk 1.6.0_45 → jdk1.8.0_301 버전 올렸더니 (오류 : Servlet.service() for servlet jsp threw exception)

Question

안녕하세요.자바메일 개발을 위해 jdk 버전을 1.8로 설정하고 서버를 실행하면아래와 같은 전문 오류가 납니다.프로젝트는 jdk 1.6.0으로 설계되었습니다.오류난 at org.apache.jsp.include.header_jsp._jspService(header_jsp.java:201)부분을 확인해보니 baseConn.close();이부분이었고 header.jsp파일을 찾아보니 이부분입니다. <% } response.flushBuffer(); resultList0.clear(); baseConn.close(); %>이부분에서 nullpoint 값이 떨어집니다.1.6으로 돌아갈때는 아무이상없는데 어떤 조치를 취해야 할까요?? 오류 전문:12월 16, 2021 10:21:34 오전 org.apache.catalina.core.AprLifecycleListener init 정보: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: C:\Program Files\Java\jdk1.8.0_301\bin;C:\WINDOWS\Sun\Java\bin;C:\WINDOWS\system32;C:\WINDOWS;C:/Program Files/Java/jre1.8.0_301/bin/server;C:/Program Files/Java/jre1.8.0_301/bin;C:/Program Files/Java/jre1.8.0_301/lib/amd64;C:\Program Files\Common Files\Oracle\Java\javapath;"C:\Program Files\Microsoft MPI\Bin\;";C:\Program Files (x86)\Common Files\Oracle\Java\javapath;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\WINDOWS\System32\OpenSSH\;C:\Program Files (x86)\Microsoft SQL Server\150\DTS\Binn\;C:\Program Files (x86)\PuTTY\;C:\Program Files\Git\cmd;C:\Program Files\Microsoft SQL Server\Client SDK\ODBC\130\Tools\Binn\;C:\Program Files (x86)\Microsoft SQL Server\140\Tools\Binn\;C:\Program Files\Microsoft SQL Server\140\Tools\Binn\;C:\Program Files\Microsoft SQL Server\140\DTS\Binn\;C:\Program Files (x86)\Microsoft SQL Server\140\DTS\Binn\;"%classpath%;.";C:\Program Files\Java\jdk1.8.0_231\bin;npm install;C:\Program Files odejs;C:\Program Files (x86)\ePapyrus\PDF-Pro 5;C:\Program Files (x86)\ePapyrus\Papyrus-PlugIn-web;C:\Program Files (x86)\ePapyrus\Papyrus-PlugIn-web\Addins;c:\Work\전자소송프로그램(PC버전);c:\Work\전자소송프로그램(PC버전)\Pdf;c:\Work\전자소송프로그램(PC버전)\Pdf\Addins;C:\Program Files (x86)\NetSarang\Xshell 7\;C:\Users\82107\.windows-build-tools\python27\;C:\Users\82107\AppData\Local\Microsoft\WindowsApps;C:\Program Files\Java\jdk1.8.0_231\bin;C:\Program Files\Git\cmd;C:\Users\82107\AppData\Local\Programs\Microsoft VS Code\bin;C:\Users\82107\AppData\Local\Google\Cloud SDK\google-cloud-sdk\bin;npm install;C:\Program Files odejs;C:\Users\82107\AppData\Local\Microsoft\WindowsApps;;C:\Users\82107\Downloads\eclipse-jee-neon-3-win32-x86_64\eclipse;;. 12월 16, 2021 10:21:34 오전 org.apache.tomcat.util.digester.SetPropertiesRule begin 경고: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.jee.server:heaven' did not find a matching property. 12월 16, 2021 10:21:35 오전 org.apache.coyote.http11.Http11Protocol init 정보: Initializing Coyote HTTP/1.1 on http-9090 12월 16, 2021 10:21:35 오전 org.apache.catalina.startup.Catalina load 정보: Initialization processed in 611 ms 12월 16, 2021 10:21:35 오전 org.apache.catalina.core.StandardService start 정보: Starting service Catalina 12월 16, 2021 10:21:35 오전 org.apache.catalina.core.StandardEngine start 정보: Starting Servlet Engine: Apache Tomcat/6.0.37 12월 16, 2021 10:21:36 오전 org.apache.catalina.core.ApplicationContext log 정보: Initializing Spring root WebApplicationContext INFO : org.springframework.web.context.ContextLoader -

보통 상위버전은 하위버전을 웬만해서는 다 수용할텐데혹시 프로젝트의 java 컴파일러 버전 설정도 변경하셨나요?

header.jsp 와 header_jsp.java 파일은 별개의 파일입니다..header.jsp 를 기반으로 header_jsp.java 파일을 만들게 되고 이렇게 생성된 java 파일을 기반으로 클래스 파일을 만들게 됩니다..그러니 header_jsp.java 파일을 직접 찾아서 에러가 발생한 곳을 다시 찾으세요..

아 제가 글을 오해하게끔 썼군요 header_jsp.java 쪽에서 확인했을떄 baseConn.close();이부분에서 오류가 났고 header.jsp에서 해당부분 찾아보니 저 부분이었습니다.

이거는..확실한건 아닌데..체크는 해보셔야 할것 같아서..header.jsp 가 추측엔 아마 include 된 파일인거 같은데.. 그러면 java 파일로 만들때는 이 코드가 include가 된 파일에 합쳐진 상태로 컴파일이 될 것 같아서요..즉 list.jsp 에 header.jsp 가 include 되었다면 list.jsp 가 java 로 변환된 list_jsp.java 에 header.jsp 관련 코드가 같이 들어가 있는 상태로 컴파일이 될겁니다..그래야 하나의 클래스 파일로 만들어질테니까요..한번 이 부분도 체크해보심이 어떨까요..? 그렇게 묶어서 전체 맥락을 봐야 하지 싶네요..

커넥션문제같은데 jdbc 버전 확인해보세요

jdk 1.6.0_45 → jdk1.8.0_301 버전 올렸더니 (오류 : Servlet.service() for servlet jsp threw exception)
