I guess you are not using Alfresco SDK for your development. If u are not using SDK, first download SDK then you will get some examples. After that ur development becomes easy.
Any way, I hope the following code will help you.

public static void uploadFile(){
      String msg="";
      try {
         String fileName="";
         String title="testfile";
         String description="xml file";
         //String path = "C:/LL Data/ATAD/Alfresco-Labs-3Stable-OOo-Setup.exe";
         String path = "C:/application-context.xml";
         path = path.replaceAll("\\\\", "/");
         fileName = path.substring(path.lastIndexOf('/')+1,path.length());
         String ext= fileName.substring(fileName.lastIndexOf('.')+1,fileName.length());
         System.out.println("FileName    ==== >> "+fileName);
         System.out.println("Path       ==== >> "+path);
         String contType="";

         if(ext.equals("txt"))
         contType = "text/plain";
         else if (ext.equals("xls"))
         contType = "application/vnd.ms-excel";
         else if (ext.equals("doc"))
         contType = "application/msword";
         else if (ext.equals("html") || ext.equals("htm"))
         contType = "text/html";
         else if (ext.equals("jpg") || ext.equals("jpeg"))
         contType = "image/jpeg";
         else if (ext.equals("bmp"))
         contType = "image/bmp";
         else if (ext.equals("pdf"))
         contType = "application/pdf";
         else if (ext.equals("ppt"))
         contType = "application/vnd.ms-powerpoint";
         else if(ext.equals("xml"))
         contType = "text/xml";
         else if (ext.equals("zip"))
         contType = "application/vnd.ms-zip";
         else if (ext.equalsIgnoreCase("wm"))
            contType = "video/x-ms-wm";

         Store storeRef = new Store(Constants.WORKSPACE_STORE, "SpacesStore");
         RepositoryServiceSoapBindingStub repositoryService = null;
         Reference content = null;
         if(contType.equals(""))
         {
            contType = getMimeType(fileName);
         }
         if(contType.equals(""))
         {
            msg="Unknown file format. File not uploded.";
         }
         else
         {
            AuthenticationUtils.startSession("admin", "admin");

      //      create content
      //       Construct CML statement to create content node
      //       Note: Assign "1" as a local id, so we can refer to it in subsequent
