Hello Friends, if you can please help,

Below seems OS level error,

I am using open source R s/w to install package that we download from internet. So we download package and then install using rstudio web client tool. Most package installed successfully but when try to install one JAVA package it error up with;

Error: Could not find or load main class .usr.lib.jvm.java-1.8.0-ibm-1.8.0.3.10.x86_64.jre
/bin/sed: -e expression #1, char 0: no previous regular expression


we have java installed
Java home path : /usr/lib/jvm/java-1.8.0-ibm-1.8.0.3.10.x86_64/jre

did internet search for this error but didn't help much...

if someone can please comment,


Thank you in advance...

Read the "Question Guidelines" link in my posting signature. Your question lacks any details necessary to even BEGIN to try to help you. You don't tell us what version/distro of Linux you're using, what this "open source R s/w" is, where you got it, if you followed their installation instructions, how you're attempting this installation, etc. We can't guess.

If your system is working, then it is obviously NOT an "OS level error", since your OS is working.

sorry everyone,

I am using Linux RHEL 6.8. R is open source software that we can download and install on our computer.

we are trying to connect to one of Teradata from this open source R. I added Driver/Description/DBCName parameters in ODBC.ini file at "/opt/Teradata/client/ODBC_64". after adding that DSN entry, need to run this command "R CMD javareconf" from command line (Putty) to add Java support to R. When I run this command as root, i receive below error,

#R CMD javareconf

this tickles something at the back of my head, about different java versions and sometimes needing to change the default via environment variables.
i know you use redhat, but archwiki has an article about that, maybe you can get something out of it:
https://wiki.archlinux.org/index.php...ng_between_JVM
it's all about the archlinux-java script it seems, which is here:

Since you're using RHEL 6.8, have you contacted Red Hat support yet too? RHEL is NOT free, and since you're paying for it (RIGHT?), you are entitled to support. They might be able to assist.

That said, it's telling you the path it's looking at for that JRE file...the obvious thing to look at would be, is that file actually THERE? Try running (as root/sudo) "find / -name *ibm-1.8.0.3.10.x86_64.jre", and see what it finds.
