p4 over http tunneling

[Former Member]

Hi guys

I have SAP NW 7.4 (only JAVA stack).

Was configure p4, add to profile this parameters

icm/server_port_2 = PROT=P4, PORT=5$(SAPSYSTEM)04

icm/server_port_3 = PROT=P4SEC, PORT=5$(SAPSYSTEM)05

and set ALLOW_NON_SSL_TUNNELING = true

can you help me, what I do wrong, I write next JAVA code but can't connect to server

import javax.naming.InitialContext;

import javax.naming.NamingException;

import java.util.Properties;

public class rmi2 {

   private static InitialContext ctx = null;

   public static void main(String[] args) {

   init ("", "10.0.0.5", "50005", "user", "1111", "httptunneling");

  }

   public static void init(String schema, String host, String port, String user, String pass, String transportType) {

   try {

  Properties p = new Properties();

   if (schema == null) {
    schema = "P4://";
   }
   p.put("java.naming.factory.initial", "com.sap.engine.services.jndi.InitialContextFactoryImpl");

  p.put("java.naming.provider.url", schema+host+":"+port);

  p.put("java.naming.security.principal", user);

  p.put("java.naming.security.credentials", pass);

   // Parameter transportType for Transport Layer Queue has value
  // "None", "ssl", "httptunneling_ssl" or "httptunneling".
   ctx = new InitialContext(p);

  System.out.println("NamingClient context: " + ctx);

  } catch(NamingException e) {

  e.printStackTrace();

  }

  }

}

get this error

hi baji,

have you found this documentation link: Getting New Initial Context Using P4 Fails - SAP NetWeaver™ Problem Analysis Guide (PAG) - SAP Libra...?

based on the "Cannot create new RemoteLoginContext instance" error messag this document mentions the following points:

• is the j2ee engine running?
• is the naming service running?
• are the url and p4 port settings correct?

i know this documentation is not for nw7.40 but since the exception is mentioned there and it also states that its validity is J2EE Engine 6.40 and higher you might give it a try.

regards,

christian

thank you for reply, but yes, all service is working. I can connect to 50004 port and call some functions, but can't connect with http protocol.

hi again

check out this documentation link Creating an Initial Context - Developing Java EE 5 Applications - SAP Library it mentions "As an external client, you have to use the InitialContext constructor with a Hashtable as a parameter, which contains environment properties specifying the connection details that should be used by the system in the context creation.".

based on your code snippet you're using Properties - try it with Hashtable instead.

regards,

christian
