Question

求大神支招， Linux 怎么安装这个sapjco3的路径啊，在调用sap接口的时候报错：

PATH：/usr/java/jdk1.7.0_25/bin:/mnt/pos/mysql/bin:
CLASSPATH：/usr/java/jdk1.7.0_25/lib:/usr/java/jdk1.7.0_25/jre/lib:/usr/java/jdk1.7.0_25/lib/sapjco3
LD_LIBRARY_PATH：/mnt/pos/sapjco3
图片为运行的测试

java.lang.ExceptionInInitializerError: Error getting the version of the native layer: java.lang.UnsatisfiedLinkError: no sapjco3 in java.library.path

Answer 1

关键是把sapjco3.so 加入到LD_LIBRARY_PATH
确认是否在这里：/usr/java/jdk1.7.0_25/lib/sapjco3
