739 I'm trying to run a simple client-server anycodings_ubuntu program written in Java through Ubuntu anycodings_ubuntu terminal. I could compile the code anycodings_ubuntu successfully unfortunately, I can't run the anycodings_ubuntu code. Server class code: import java.io.IOException; import java.net.ServerSocket; import java.net.Socket; public class Server { public static void main(String[] args) { try { //create server Socket with demo port ServerSocket server = new ServerSocket(20); //wait for server connection Socket s = server.accept(); //upon establishing connection, print // successful message System.out.println("connection eastablished"); } catch (IOException e) { e.printStackTrace(); } } }Client class code: import java.io.IOException; import java.net.Socket; import java.net.UnknownHostException; public class Client { public static void main(String[] args) { try { //create client socket Socket client = new Socket("127.0.0.1", 20); //upon establishing connection, print //successful message System.out.println("connection eastablished"); } catch (UnknownHostException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } }During running the complied class, I'm anycodings_ubuntu getting the following error:
I've tried to search stackoverflow and other anycodings_ubuntu forum and blogs to find a solution, I've anycodings_ubuntu find some similar questions, tried the anycodings_ubuntu answers provided to those question but could anycodings_ubuntu find a solution for my problem. That's why anycodings_ubuntu I'm adding this question here. Later, I've try to write a very simple Java anycodings_ubuntu program, like just to print a greeting, this anycodings_ubuntu program also could be compiled but would not anycodings_ubuntu run producing the same error. I've tried to anycodings_ubuntu execute the program from different folders anycodings_ubuntu except from the root folder. But all efforts anycodings_ubuntu produce the same result. public class Test { public static void main(String[] args) { System.out.println("Hello..."); } }I can perfectly work in Eclipse where my anycodings_ubuntu java version 8, problem occurs only when anycodings_ubuntu working in terminal. In my Ubuntu jdk version is 11 (which has anycodings_ubuntu been automatically been updated without my anycodings_ubuntu knowledge); My Ubuntu version:18.04.1 LTS Total Answers 3 31 Answers 1 : of Error: A JNI error has occurred, please check your installation and try again - during running Java program from Ubuntu terminalThe error says it all:
You've compiled for Java 11 ... but anycodings_ubuntu you're running an older JRE (Java 8). SUGGESTIONS:
EXAMPLE: javac -target 8 -source 8 anycodings_ubuntu MyClass.java FYI, these are the Java versions in each anycodings_ubuntu Java class file's header:
Also FYI, here are the command line anycodings_ubuntu options for javac: Java SE 11 > Tools > javac PS: You may have multiple independent anycodings_ubuntu versions of Java installed at the same anycodings_ubuntu time. Use the alternatives command:

This is my anycodings_ubuntu solution. There was 2 Java versions anycodings_ubuntu installed (java 8 and Java SE anycodings_ubuntu Development kit 13). This error occurs anycodings_ubuntu because of this 2 versions. Just anycodings_ubuntu uninstall old version and you are anycodings_ubuntu done. (*Java compiles .java file using anycodings_ubuntu SE Development kit and trying to execute anycodings_ubuntu using old version. So compatible errors anycodings_ubuntu occurs.) Then check java versions on cmd using anycodings_ubuntu javac -version and java -version. After anycodings_ubuntu uninstallation, both version codes must anycodings_ubuntu be same. 0 2022-08-16T17:39:27+00:00 2022-08-16T17:39:27+00:00Answer Link jidam 1 Answers 3 : of Error: A JNI error has occurred, please check your installation and try again - during running Java program from Ubuntu terminalIf you don't want to upgrade your Java anycodings_ubuntu version to Java11.
