Question

我从UnSupportedClassVersionNumber致电jar时收到.bat file例外。

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"

从eclipse我已经导出了jar。我已将jre to 1.5.0_14和编译器版本更改为1.5，然后导出jar。它仍然显示相同的错误。请帮忙。

Answer 1

中更改它

现在我可以正确运行批处理文件中的java应用程序了。

从.bat文件运行jar时出错
