setting CLASSPATH manually prevents rJava from finding getsp class for configure tests about rjava HOT 3 CLOSED

It seems that your'e not working off a proper tar ball - did you run mkdist to create a distribution tar ball?

I have had the same problem install the package rJava into R-3.1.0 on a Centos 6 environment.
Eventually worked out that my CLASSPATH variable was defined and it NOT include ".". By default java looks in the current directory if CLASSPATH has no value. If it is defined, java does not look in the current directory, hence the class getsp was not found. By defining CLASSPATH using:

export CLASSPATH=.:/my_other_classpath_directory

my installation of the rJava package worked

@gitkit7 thanks! That was indeed the actual issue here. I have added a work-ardound for cases where CLASSPATH is already overridden by the user. Note that setting CLASSPATH will cause issues down the road anyway (it may invoke a different class loader and cause confusion), so it's better to unset it.
