load main class [duplicate] up vote 225 down vote favorite 27 This question already has an answer here: What does “Could not find or 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 . could not find the main class program will exit eclipse -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_PATH_PARAM); if(libName == null || libName.trim().equals("")) { log.error("Vensim library name has to be set with -D" + DLL_LIBNAME_PARAM); throw new SpatialException("Vensim library name has to be set with -D" + DLL_LIBNAME_PARAM); } if(modelPath == null || modelPath.trim().equals("")) { log.error("Model path has to set with -D" + MODEL_PATH_PARAM); throw new SpatialException("Model path ahs to be set with -D" + MODEL_PATH_PARAM); } for (int i = 0; i < VENSIM_CONTEXT_CREATION_MAX_FAILURE_COUNT && vh == null; i++) { try { log.info("creating new vensim helper\n\tdll lib: " +

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...

This Site Careers Other all forums Forum: Beginning Java Java problem: Could not find or load class bolisetti sriharsha Greenhorn Posts: 8 posted 5 years ago I am new to java but previously i did some basic programs on my system.... i never got this error message....so i removed java sdk and reinstalled it... i set PATH variable as C:\Program Files\Java\jdk1.7.0\bin CLASSPATH variable as C:\Program Files\Java\jdk1.7.0\lib JAVA_HOME as C:\Program Files\Java\jdk1.7.0 i am unable to run even programs which i executed earlier... when i compile them ... it is not showing any error message but when i tried to run them(by using java command in command prompt) iam getting error message as "Error: Could not find or load main class Applicant" PLZZZZ Help me Guys........... sorry for my poor english THANKS IN ADVANCE Ganesh Akondi Greenhorn Posts: 6 I like... posted 5 years ago 2 To check whether JDK got installed properly or not..open command prompt and type javac ->enter You should get some list of options instead of an error message like javac is not an internal command. Then you have installed your JDK properly. Differences between PATH and CLASSPATH is: (both are environmental variables) PATH - points to bin of your java installation (system variable to tell the OS where is your JDK installed) CLASSPATH - can say java variable, which is used to tell locations of all jar/zip(classes) files to Compiler. Classpath is nothing but setting up the environment for Java. Java will use to find compiled classes eg: If we are using JDBC Driver then we need to keep classes12.jar in classpath, If we are using sevlets future then we need to keep servlet-api.jar in classpath .. like these so many places we use this. bolisetti sriharsha Greenhorn Posts: 8 posted 5 years ago Thanks for the reply..... when i typed javac and pressed enter.... it shows ..as you said a list of options.... so jdk is installed properly..
