load main class” mean? 24 answers I am having trouble compiling and running my Java code, intended to allow me to interface Java with a shared object for Vensim, a simulation modeling package. The following code compiles without error: javac -d . -cp ./apache-log4j-1.2.16/log4j-1.2.16.jar:./vensim.jar SpatialModel.java VensimHelper.java VensimException.java VensimContextRepository.java However, when I try to run the following: java -cp ./apache-log4j-1.2.16/log4j-1.2.16.jar:./vensim.jar SpatialModel vars I get the following error: "Error: Could not find or load main class SpatialModel ". My SpatialModel.java code does contain a 'main' method (below), so I'm not sure what the problem is - can anyone please help me out? Thanks. import java.io.File; import java.text.NumberFormat; import java.util.ArrayList; import java.util.Arrays; import java.util.List; import org.apache.log4j.Logger; public class SpatialModel { private VensimHelper vh; public static final String DLL_LIBNAME_PARAM = "vensim_lib_nam"; public static final String MODEL_PATH_PARAM = "vensim_model_path"; private final static int VENSIM_CONTEXT_CREATION_MAX_FAILURE_COUNT = 10; public SpatialModel() throws SpatialException { String libName = System.getProperty(DLL_LIBNAME_PARAM); String modelPath = System.getProperty(MODEL

Gepubliceerd op 2 mrt. 2016First we can successfully compile with setting path of Java program ,But wile run that simple program we will get an error : "could not find or load main class in java ".Why it happens ?Because we can compile our java programs with their paths ,but while running that program we get an error : could not find or load main class in java,because JVM could not load that .class from that directory...In my case i have written one simple java program ,I was save simple program in F:\ drive i can compile my program through its path 1.C:\Program Files 86\Java\jdk1.8.0\bin javac F:\Test.java2.It can compile successfully ,but when i am trying to run above program ,i got an error "could not find or load main class in Test.java "3.So to avoid that problem we need to change our directory path where actually our .class file is exists and also we need to set path and class path too..4. Then you wont get any errors ,you can run program happily ...Thank you guys ...for more information see my blog : ensuretoday.blogspot.com Categorie Mensen & blogs Licentie Standaard YouTube-licentie Meer weergeven Minder weergeven Laden...

or load main class in Java [Solved] Error: Could not find or load main class HelloWorld comes when you are trying to run your Java program using java command with the main class as HelloWorld but Java is not able to find the class. In order to http://javarevisited.blogspot.com/2015/04/error-could-not-find-or-load-main-class-helloworld-java.html solve this error, you must know how Java find and loads the classes, that's a https://coderanch.com/t/552833/java/java/run-time-error-find-load little bit complex topic for beginners, but we will touch the same base here. For the curious reader, I would suggest reading my post How Classpath works in Java, a must read for a beginner. For now, you just remember that there is an environment variable called CLASSPATH which includes directories where Java looks for all class files and if it doesn't find could not your main class there then it throws "Error: Could not find or load main class XXX", where XXX is the name of your main class. Since many Java programmer is now started programming using Eclipse they face this issue when they first try to run their Java program from command line. In Eclipse, it's easy to compile and run the program because Eclipse takes care of all Classpath setup, but when you run your Java program from command line, could not find CLASSPATH environment variable comes in picture. Personally, I don't like this environment variable and doesn't define in my environment variable, because its confusing and source of so many classpath related issue. Instead, I use -cp or -classpath option with java command to run my program. This way you always know which JARs are included in your classpath. For beginners, another important thing to understand is the difference between PATH and CLASSPATH, you must know that PATH is used locate system executable, commands or .exe, .dll files (in Windows) and .so files (in Linux). It is also used to locate native libraries used by your Java program. While, CLASSPATH is used to locate the class file or JAR files. It's Java class loader who looked into CLASSPATH for loading classes. Coming back to the problem in hand, if you are a beginner in Java, who are able to run the program from Eclipse but getting "Error: Could not find or load main class HelloWorld" when trying to run the same program from the command line then follow the steps given here to solve it. Solving Error: Could not find or load main class HelloWorld Unfortunately beginner's book like Head First Java, which many developers used to learn Java, doesn't teach you how to deal with this kind of errors. You need to build this skill by doing active development. In order to understand the prob
