404 error while invoking servlet in weblogic 6.0

Question

          Hi,
          When I try to invoke a servlet from weblogic 6.0, I am getting
          404 error. I have copied the HelloWorldServlet class into defaultWebAppl_Server/WEB_INF/CLASSES
          directory and when I invoke the HelloWorldservlet, its giving file
          not found(404) error. I am doing exactly what has been given in
          the "quick start to servlets" in weblogic 6.0. I am using Windows
          NT.
          I have also another problem when I use java utils.dbping to test
          the connection to my oracle8.1.8, its giving licence file not found.
          Could some one help me out from this.
          Thanks in advance,
          Ramu

          Hi kumar,
          I have been keep trying to solve that. After some time Suddenly
          "Error 404" disappeared and instead "Error 500" came. Okay kumar,
          here is what I am doing...
          I have installed weblogic6.0(eval), oracle 8.1.6 on Windows NT4.0.
          I have installed oracle Enterprise edition from CD "ORACLE 8.1.6
          for NT".
          I installed the weblogic under D: drive.
          I did class path settings as given in documentation. But Iam not
          sure whether I need to do any other class path settings.
          I was able to run pet store application given in weblogic server.
          I went to "quick start" section and ran HelloWorld.jsp page from
          "DefaultWebApp_myServer" directory.
          I was not able to run servlet program as per given in the "quick
          start". I am getting
          "Error 500---Internal server error"
          The server encountered an unexpected condition which prevented
          it from fulfilling the request"
          I have modified the web.xml under WEB-INF of DefaultWebApp_myServer
          as per given in the quick start.
          Here is the quick start link For you reference(as what I talking
          about)
          http://edocs.beasys.com/wls/docs60/quickstart/quick_start.html
          In the web.xml, I have given <servlet-class> as just HelloWorldServlet,
          since I directly copied the file from some other examples directory.
          But still I am getting 500 error.
          Here is the url that I am invoking...Http://ramup:7001/quickStartServlet
          Coming to your oracle connection test, I did exactly what you said.
          kumar, I have executed the command
          "D:\bea\wlserver6.0\config\mydomain>java -classpath %classpath%;D:\bea
          utils.dbping ORACLE
          >scott tiger TestDB"
          Where TestDB is the database that I have created while installing,
          but I am not aware of the instance you said.
          Here is what I got after executing the command.
          --------*******-------Pasting the ms-dos command results----**-
          // This mode is superior, especially in serverside classes because
          // it avoids DriverManager calls are class synchronized, and will
          // bottleneck any other JDBC in the server, even already-running
          // connections, because all JDBC drivers use DriverManager.println()
          // to log info and exceptions, and that call is also class synchronized.
          // For repeated connecting, a single driver instance can be re-used.
          **** or ****
          Class.forName("weblogic.jdbc.oci.Driver").newInstance();
          java.sql.Connection conn =
          DriverManager.getConnection("jdbc:weblogic:oracle:TestDB", "scott",
          "tiger")
          **** or ****
          java.util.Properties props = new java.util.Properties();
          props.put("user", "scott");
          props.put("password", "tiger");
          props.put("server", "TestDB");
          Class.forName("weblogic.jdbc.oci.Driver").newInstance();
          java.sql.Connection conn =
          DriverManager.getConnection("jdbc:weblogic:oracle", props);
          D:\bea\wlserver6.0\config\mydomain>
          --------*******-------Pasting the ms-dos command results----**-
          I think I have connection to database, thanks for your suggestion.
          Kumar, I have not seen weblogic.properties file any where in D:\bea
          directory.
          Kumar, if you have some time can you jot down the classpath settings
          and path settings for executing SERVLETS/EJB programs.
          Thanks for helping me out..,
