    Default Java command line

    Hello to everyone,

    I decided to post this thread in this forum and not in Eclipse because I am new to Java and this question is technically not an eclipse one :)

    So here is the question:

    I compile and run this program in Eclipse and it works perfect.

    I am trying to incorporate it in another application by means of a comand line interface ... the application has means of sending a command to a cmd command
    interpreter and executing it. When I try and test this on the command line I get the following error:

    Exception in thread "main" java.lang.NoClassDefFoundError: myclass (wrong name: com/example/java/swiss/myclass)

    I thought this could be due to my environment not being set-up correctly. So added the following to my CLASSPATH and PATH:

    C:\Work\Java Work Space\src\com\example\java\swiss;C:\Work\Java Work Space

    C:\Work\Java Work Space\TonerWebService\lib; <==== where the class (in a jar file) my program is calling is located
    C:\Work\Java Work Space\TonerWebService\lib\ ttpConnection.jar; <==== the jar itself
    C:\Work\Java Work Space\TonerWebService\classes\com\example\java\swi ss <==== where the compiled class (main) is located

    I also tried the following and get the same error.

    Java -cp "C:\Work\Java Work Space\TonerWebService\lib;C:\Work\Java Work Space\TonerWebService\lib\ ttpConnection.jar" myclass

    I also included -jar "<PATH TO JAR>" but without success.

    Do you have any idea as to where I am going wrong? Is there anything I am missing???

    Is there any where in Eclipse you can capture the java command line that the IDE executes to run myclass .. perhaps some log file or a way that this command line can be generated within the IDE??

    Classpath is the path to where your JDK instalation can be found. Not the working folder. Something like this,

    c:\programme\j2sdk1.4.2_08\jre\lib; .........

    Default Classpath

    Many thanks Eranga...

    My class path already has the followings but did not incluce them in my previous pot:

    C:\Archivos de programa\Java\jre1.5.0_08\lib;
    C:\Archivos de programa\Java\jre1.5.0_08\bin

    So yes I have the path to the JRE included as well and get the same error.
