Java error when

[xiaodaigh]

Error in .jnew("s7b2csvclass") :
java.lang.UnsupportedClassVersionError: s7b2csvclass : Unsupported major.minor version 51.0

I get this error when running read.sas7bdat on my Mac. From my internet search it mentioned something about the java class being compiled to a lower version? I am using Java 8. Is the jar files compiled into java 1.6 format or something?

I used Java 7 (major version 51) to compile the class. I'm not sure why
your version of Java won't run it; I'm not a Java programmer.

Hi,

Same problem here, on osx and JDK 8u45.
So I installed the JDK 7u80 : idem.
So I tried to install the JDK 7u51, but my os version is not supported (only 10.7.3, my os is 10.10.3).

Any idea..?

Bien à vous

you have java 1.8 it maybe running java 1.6 ... seeing it i can found it.

FYI, I'm a C and R programmer; very little Java. I had to tinker with this
for almost a week to get it to work. I'm sure that it's suboptimal. Happy
to have feedback.

Thanks
