I ran into the exact same issue. My solution was to install the openjdk-7-* via

<pre><code>sudo apt-get install openjdk-7-*
</code></pre>

Followed that with

<pre><code>sudo R CMD javareconf
</code></pre>

and I was then able to install rJava in R via <code>install.packages("rJava")</code>.

While perhaps not the most elegant solution it appears to have solved my problems with getting rJava to work.

For those getting the error:

I solved the error locating the library in the system and linking them to <code>/usr/lib</code>:

blocks|key|322082|text|按照this+askUbuntu+answer中的建议，从发行包安装rJava也是可行的：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|322083|sudo+apt-get+install+r-cran-rjava|code-block|syntax|javascript|322084|注意:在Debian系统中尝试过。|322085|entityMap|0|LINK|mutability|MUTABLE|url|https://askubuntu.com/questions/858961/install-rjava-on-ubuntu-failed^0|2|L|0|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@$A|T|B|U|1|V]]|C|$]]|$1|D|3|E|5|F|7|W|8|@]|9|@]|C|$G|H]]|$1|I|3|J|5|6|7|X|8|@]|9|@]|C|$]]|$1|K|3|-4|5|6|7|Y|8|@]|9|@]|C|$]]]|L|$M|$5|N|O|P|C|$Q|R]]]]

Installing rJava from the distribution packages as proposed in <a href="https://askubuntu.com/questions/858961/install-rjava-on-ubuntu-failed">this askUbuntu answer</a> also works:

<pre><code>sudo apt-get install r-cran-rjava
</code></pre>

NOTE: tried from a Debian system.

I was also facing same error which was on RHEL8.1 &amp; i resolved it as follows:

<pre><code>yum --enablerepo=* install java-1.8* 
</code></pre>

later i ran same command which was giving me error logs of R server.

<pre><code>R CMD javareconf
</code></pre>

which turns into following output.
