從.bat文件運行jar時出錯

Question

從.bat file調用jar ，出現UnSupportedClassVersionNumber異常。

set LIBRARY_PATH=D:\endecabatch\JAR

echo %LIBRARY_PATH%

set JAVA_HOME=C:\Java\jdk1.5.0_14 

set PATH=%JAVA_HOME%\bin;%JAVA_HOME%\lib

set CLASSPATH=%PATH%

set CLASSPATH=%CLASSPATH%;%LIBRARY_PATH%\sqljdbc.jar

set CLASSPATH=%CLASSPATH%;%LIBRARY_PATH%\log4j-1.2.16.jar

set CLASSPATH=%CLASSPATH%;%LIBRARY_PATH%\auditlog_1.0.jar

set CLASSPATH=%CLASSPATH%;%LIBRARY_PATH%\jdbc_1.0.jar

set CLASSPATH=%CLASSPATH%;%LIBRARY_PATH%\EndecaBatch.jar

java -classpath %CLASSPATH% com.heb.endeca.batch.BatchManager "D:\endecabatch\" "properties\LOCAL\" "FULL" "ALL" 

從蝕我出口了那個瓶子。 我將jre to 1.5.0_14更改jre to 1.5.0_14並將編譯器版本更改為1.5 ，然后導出了jar 。 仍然顯示相同的錯誤。 請幫忙。

這是我得到的Exception

Answer 1

實際上，我在生成jar時犯了一個錯誤。 我在buildPath -> ConfigureBuildPath -> compiler windows-> Preferences更改了編譯器版本，而不是在buildPath -> ConfigureBuildPath -> compiler中更改了它

現在，我可以從批處理文件正確運行我的Java應用程序了。
