So it executed the Servlet Login2 as evidence in the stacktrace....
> root cause > > java.lang.NoClassDefFoundError > at Login2.doGet(Login2.java:51) > at > javax.servlet.http.HttpServlet.service(HttpServlet.java:740) ... and it got all the way to line 51. It looks like there are other classes from this jar package that are being invoked. If they are being invoked with no exception then the jar file is found. But the class at line 51 is not found. My line counting isn't working so you need to point to the source code line 51. Also assuming your classes are like this: com.sap.mw.jco.JCO.Repository and the jco.jar file is in your WEB-INF/lib directory. > -----Original Message----- > From: Korakaki Stella [mailto:[EMAIL PROTECTED]] > Sent: Thursday, March 28, 2002 4:39 AM > To: Tomcat Users List > Subject: Apache Tomcat/4.0.3 - HTTP Status 500 - Internal Server Error > -HELP-ME-PLEASE > > > > When I'm trying to execute the following servlet from the > web browser: > --------------------------------------------------------------------- > > import com.sap.mw.jco.*; > import java.io.*; > import javax.servlet.*; > import javax.servlet.http.*; > > public class Login2 extends HttpServlet > { > > JCO.Client mConnection; > JCO.Repository mRepository; > > public JCO.Function createFunction(String name) throws Exception { > try { > IFunctionTemplate ft = > mRepository.getFunctionTemplate(name.toUpperCase()); > if (ft == null) > return null; > return ft.getFunction(); > } > catch (Exception ex) { > throw new Exception("Problem retrieving JCO.Function object."); > } > } > > public void doGet (HttpServletRequest req, > HttpServletResponse res) > throws ServletException, IOException > { > > res.setContentType("text/html"); > PrintWriter out = res.getWriter(); > String tmp; > > out.println("<html><body>"); > > try { > // Change the logon information to your own system/user > mConnection = > JCO.createClient("300", // SAP client > "username", // userid > "********", // password > "EN", // language > "127.0.0.1", // application server host name > "00"); // system number > mConnection.connect(); > mRepository = new JCO.Repository("ARAsoft", mConnection); > } > catch (Exception ex) { > ex.printStackTrace(); > System.exit(1); > } > > JCO.Function function = null; > JCO.Table codes = null; > try { > function = this.createFunction("ZRFC_CUSTOMERS"); > if (function == null) { > System.out.println("ZRFC_CUSTOMERS" + > " not found in SAP."); > System.exit(1); > } > > JCO.ParameterList input=function.getImportParameterList(); > input.setValue("0001","BUKRS"); > > mConnection.execute(function); > > codes = > function.getTableParameterList().getTable("CUSTOMER"); > for (int i = 0; i < codes.getNumRows(); i++) { > codes.setRow(i); > > tmp=codes.getString("NAME1"); > if (tmp.length() < 12 ) { > out.println("<li>");out.println(tmp);} > else {out.println("<li>");out.println(tmp.substring(0,12));} > } > } > catch (Exception ex) { > ex.printStackTrace(); > System.exit(1); > } > out.println("</body></html>"); > > mConnection.disconnect(); > > } > } > -------------------------------------- > -------------------- > Stella Korakaki > Koutoudis Consulting > > > -- > To unsubscribe: <mailto:[EMAIL PROTECTED]> > For additional commands: <mailto:[EMAIL PROTECTED]> > Troubles with the list: <mailto:[EMAIL PROTECTED]> > -- To unsubscribe: <mailto:[EMAIL PROTECTED]> For additional commands: <mailto:[EMAIL PROTECTED]> Troubles with the list: <mailto:[EMAIL PROTECTED]>
