i just installed Rstudio and wanted some packaes to use, im using linux mint, when i tried to install the xlsx package give an error related to rjava, so i installed the rjava package, but it cant be loaded, instead i get this error: 

>library("rJava", lib.loc="/usr/lib/R/site-library")
Error : .onLoad failed in loadNamespace() for 'rJava', details:
call: dyn.load(file, DLLpath = DLLpath, ...)
error: unable to load shared object '/usr/lib/R/site-
library/rJava/libs/rJava.so':

Error: package or namespace load failed for ‘rJava’
>detach("package:rJava", unload=TRUE)
Error in detach("package:rJava", unload = TRUE) : invalid 'name'

I tried R CMD javareconf several times, but still no clue of the problem

You may want to locate the library, you can use the whereis command or look into standard path which are : /usr/lib/jvm/java-7-oracle/lib/amd64 /usr/lib/jvm/java-7-oracle/jre/lib/amd64/server

Once it's located, copy its folder's path.

Then add it to the LD_LIBRARY_PATH environment variable located in ~/.profile (create the file if needed). export LD_LIBRARY_PATH=/usr/lib/jvm/java-7-oracle/lib/amd64:/usr/lib/jvm/java-7-oracle/jre/lib/amd64/server

If you already have a LD_LIBRARY_PATH set you may want to keep it, so echo $LD_LIBRARY_PATH and add its content into the ~/.profile file.

You can reboot to reload the .profile, or you can just source ~/.profile form a terminal.

To conclude just sudo R CMD javareconf.
