I would like to call an R script from Java. I have done google searches on the topic, but almost all of the results I have seen would require me to add a dependency to some third party library. Can anyone show me a good way to accomplish the same thing without adding any dependencies to my code?
I'm setting up a new application which runs R script file from java using the following line
Runtime.getRuntime().exec("C:\\Users\\Thiru\\Desktop helloWorld.R");
but when I run the application I am getting following exception:
SEVERE: Servlet.service() for servlet [RenjinServlet] in context with

[/REngineCheck] threw exception

You should set up your path in a bracket like
("your_path\Rscript.exe your_path\filename.R")
If you set the environment, you can use Rscript
Example:
Runtime.getRuntime().exec("C:\\Program Files\\R\\R-3.6.1\\bin\\x64\\Rscript.exe C:\\Users\\Thiru\\Desktop\\helloWorld.R");

Recently install Jenkins by downloading its war file(jenkins.war), and installation I downloaded some maven plugins and then I tried to restart it again but did not find any way to restart it.
so I just open the cmd and hit the command java -jar jenkins.war. After that Jenkins stops(cmd showing the message: jenkins.model.Jenkins#cleanUp: Jenkins stopped).
Now how can I start it again, when I am hitting the localhost:8080/jenkins, it is showing the above error.

Before importing project on eclipse I execute the 'gradle eclipse' command and everything goes well.
What I could do?
Thanks.
There was a bug in Gradle up to Version 3.4(?), where spaces within the build path were not allowed
https://github.com/gradle/gradle/issues/1180
Because your build path contains a space because of "Eclipse Neon" it will fail.
Suggestions:
Either update to the latest version
or try to prevent the error by moving your eclipse neon installation so the path does not include spaces
I installed Apache server (Tomcat 7.63) on client machine (Window 7 system 32 bit), The Java version used in client machine is (JDK 1.8 update 60)
Problem
Tomcat server is started by running the file (...\bin\Tomcat7.exe). But when I tried to open the home page (http://localhost:8080/) it is not coming on browser and I can see the following exception on Apache log:

What is really weird to me that if I start Apache server from Services Management Console from the administrator account: Administrative Tools -> Services , it is working fine and I can see that the home page (http://localhost:8080/) is coming on browser.
Question
Why Apache home page is not coming if we run Apache server using the .exe file (...\bin\Tomcat7.exe) ? Why the home page is coming if the server started using Windows service ? In both cases the same .exe file is execute to run the server, what is the difference between the two cases ?
Tomcat cannot be started by using the exe directly (unless the correct parameters are supplied), you should use one of the included .bat files if you want to do that: startup.bat
Just be sure to define your environment variables, such as JAVA_HOME, and/or JRE_HOME
I try to introduce with apache Solr. At this resource I find out popular question: Apache Solr java tutorials

update

It is not finding your solr config file:

Double check to see if your solr config file is in the specified directory.
