I have a jersey client. I have the following imports in the client class
import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.client.Entity;
import javax.ws.rs.client.Invocation;
import javax.ws.rs.client.WebTarget;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
When I compile the application I get
./src/com/uciext/ws/class2/client/StudentClient.java:3: error: package javax.ws.rs.client does not exist
import javax.ws.rs.client.Client;
^
How can I fix the issue

This is the c.sh. I use jersey 2.2.7. I downloaded jersey 2.2.7 and copied it in my lib folder. Can I have the wrong version of jar.

Have you included the dependencies to get the implementation of this package?
If you are using maven this post give the details.
For library version, download libraries from here and follow the following tutorial for adding the required jars. Although the Client class is available in jaxrs-ri\api jar.
You want to grab this zip file and make sure the jaxrs-ri/api/jakarta.ws.rs-api-2.1.6.jar is in your classpath.

I have a maven project (folder ev) and I want to run a java class (ChargerLocation.java) from the cmd. I 've tried the link but didn't work. When I run the ChargerLocation.java from Eclipse it works but I want to run it from the cmd.
It looks like that I should be able to run by: Run Configurations->Show Command Line and paste that in my cmd, however I get the following error'-classpath' is not recognized as an internal or external command, operable program or batch file.
In order to do the: Run Configurations->Show Command Line-> paste in cmd, in which folder should I be located?
I was wondering whether the command at the cmd should be something like Maven/apache-maven-3.6.3/bin/mvn exec:java -Dexec.mainClass="" since it's a maven project as a whole? Or it doesn't matter?
By simply doing javac ChargerLocation.java I get 45 errors which seem to be like it cannot find the proper libraries to build.

I also attach a photo of my folders in eclipse.
Finally, I want to call this java file from Python, so what I am trying to do here is: open cmd from Python (os.system()) with pre-written command to call java Class (ChargerLocation.java) and finally run the java class.
Thanks in advance
#howlger here is the command line I get from eclipse.
It's not the arguments that increase the number of characters but the different jar libraries that needs to be build first before running my main java file org.matsim.contrib.ev.example.ChargerLocation
As far as I understand the argfile is to write arguments, which in my case there aren't any.
The following is my system configuration: windows8.1, vmware v12, 2 centOS VMs. I have installed hadoop on my VMs, one as master and the other as slave1. The services are correctly up and running on both nodes.
I want to compile my first mapreduce program, the wordcount tutorial:
I'm trying to compile using the following:

I googled and everyone said it's due to $CLASSPATH.
this is my /etc/bashrc file:
export JAVA_HOME=/opt/jdk
export JRE_HOME=/opt/jdk/jre
export PATH=$PATH:/opt/jdk/bin:/opt/jdk/jre/bin
export HADOOP_CLASSPATH=$JAVA_HOME/lib/tools.jar
export HADOOP_HOME=/opt/hadoop/

any idea why I get this error?? I see no problem... :(
According to the documentation you can do the following (tested on my system and works)
export HADOOP_CLASSPATH=${JAVA_HOME}/lib/tools.jar
$HADOOP_HOME/bin/hadoop com.sun.tools.javac.Main WordCount.java
and finally create the jar using
jar cf wc.jar WordCount*.class

Got the same error, but
Closing android studio,cleaning the build and again rebuilding it solved my error.
I'm new with spark, and I want to use the Fp Growth found in Mllib with java and maven. But I get this error during the compilation:
[ERROR] COMPILATION ERROR :
[INFO] -------------------------------------------------------------
[ERROR] /home/cjd/fpgexample/src/main/java/org/fpgexample/FpgTest.java:[25,7] cannot find symbol

this are the imports and the error line:
package org.fpgexample;

import org.apache.spark.mllib.fpm.FPGrowth;
import org.apache.spark.mllib.fpm.FPGrowthModel;
JavaRDD<List<String>> transactions = data.map( new Function<String, List<String>>() {`
I update the maven compiler to the 3.3 (using JDK 1.7), and spark-core and mllib 2.11 (1.5.1) versions. (with the mllib 2.10 1.4 maven didn't recognize the fpm.AssociationRules).
EDIT: I changed the maven compiler, pom.xml and JDK to 1.8 from 1.7, but the error persist.
You should import the correct package as below:
import org.apache.spark.api.java.function.Function;
I'm trying to compile this very simple JUnit test on my Windows 10 box:
import static org.junit.Assert.assertTrue;
import org.junit.Test;
public class TestHelloWorld
{
#Test
public void BasicTest ()
{
assertTrue(true);
}
}
However, this seemingly innocuous task has proven impervious to three to four hours of research and trial and error.
From a Cygwin terminal I see this:
javac -cp lib/hamcrest-core-1.3.jar:/lib/junit-4.12.jar:. TestHe
TestHelloWorld.java:1: error: package org.junit does not exist
import static org.junit.Assert.assertTrue;

TestHelloWorld.java:9: error: cannot find symbol
assertTrue(true);

5 errors
and from a CMD prompt I see this:
javac -cp C:\Users\canon\Documents\GitHub\cse1341\AssignmentTester\lib\junit.jar TestHelloWorld.java
error: error reading C:\Users\canon\Documents\GitHub\cse1341\AssignmentTester\lib\junit.jar; error in opening zip file
1 error
I honestly have no idea what I'm doing incorrectly here. I've always been on a *nix machine before, where I don't recall having any problems compiling JUnit tests when I pass in the junit and hamcrest jars to the class path using the -cp flag. Any ideas or guidance here would be much appreciated!
There are two thing:
Java in windows using ';' to separate the jar files in classpath argument so it should be
"javac -cp lib/hamcrest-core-1.3.jar;/lib/junit-4.12.jar;. TestHeTestHelloWorld.java" in cygwin
check if C:\Users\canon\Documents\GitHub\cse1341\AssignmentTester\lib\junit.jar is a valid jar. (you can use zip tool to check).
The slash before lib/junit-4.12.jar seems to be wrong.
