LDAP acces via SSL - javax.net.ssl.SSLHandshakeException

March 22, 2013, 5:58 am

Hello All

 

I'm trying to fing reason for non-working SSL connection from java app (EJB) to LDAP server.

 

Code is:

 

env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
System.setProperty("ssl.ServerSocketFactory.provider","oracle.security.ssl.OracleSSLServerSocketFactoryimpl");
env.put(Context.PROVIDER_URL, urlLdapServer + baseDN);
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, "user");
env.put(Context.SECURITY_CREDENTIALS, "password");

 

And while trying to connect exception is thrown:

 

Exception while getting data from LDAP:

javax.naming.CommunicationException: simple bind failed: server_address:636 [Root exception is javax.net.ssl.SSLHandshakeException:

sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException:

unable to find valid certification path to requested target]

 

In portal's configuration there is key storage named TrustedCAs containing valid certificate for this LDAP server.

 

I'm bit stuck, so any help would be highly appreciated.

 

Thanks in advance

Hi All,

 

I am executing a JCO Program which triggers a RFC using JCO's <b>execute(String functionName)</b> method.

 

RFC inturn calls an SAP interface which process the goods issue files.

 

After processing few files i get a connection closed error.

 

In seeing in Transaction ST22 the error was DYNPRO_SEND_IN_BACKGROUND

 

When executed in SAP GUI the error never comes and also when the abapDebug is set to true

 

and its strange that its coming after processing some few files.

 

Any Idea

Hello everyone,

 

I want to know the basic idea on how to make a RFC call to SAP from JAVA.

 

What are the pre-requisites for it ? What are the tools (JAVA tools , DLL files etc ) required before I can make a RFC call? Basically I am asking for a high level design with basic technical pre-requisites.

 

 

Thanks-

Harmeet.

Java EE concepts for Portals custom development

Hi Gurus,

 

Which concepts of Java EE are helpful/required for custom development of Netweaver Portals?

 

What I am trying to find is the list of Java EE topics that are redundant as far as Netweaver Portals are concerned. In that case, I can only concentrate on relevant topics.

 

Or should I take an EE book and read from start to finish?

 

Thank you.

Hi all,

As far as I know, SAP's bleeding edge AS (NW73 AS) is based on EE5.

As several java AS vendors are releasing EE6 compliant products, I would like to know whether any deadline has been set for SAP's EE6 app server release.

 

Thanks in advance

Java RFC Connection: Step by step

June 7, 2011, 2:00 am

Hi folks,

 

my first goal is to achieve a remote function call from Java to SAP or the other way.

My first attempt is a Java application which does a RFC to a SAP ABAP function that returns me some database data, but more about that later.

The first thing where i already fail is to build up a simple connection between Java and SAP.

I tried it with JCo v2.1.x and JCo v3.x (Which version should i prefer? are there advantages, disadvantages?)

Here are the two approaches:

{JCO v2.1.x}:

 

          
JCO.Client myConnection = JCO.createClient("001",                                                               "***",                                                                "****",                                                                "DE",                                                                "***",                                                                "00");
myConnection.connect();
...
...

 

 

I get a "(103) RFC_ERROR_LOGON_FAILURE: Userid or password incorrect". I put in my normal SAP GUI account. Its not an admin account but i can create reports etc in the ABAP Editor.

I checked the spelling several time and it should be ok. Why does it say incorrect user or password?

Is this possible because of insufficient rights?

 

{JCo v3.x}:

I just tried the "StepByStepClient" example included in the sapjco3 download and i saw that every connect function begins with a "JCoDestination destination = JCoDestinationManager.getDestination(String);" line.

But what exactly does this getDestination function do? What string do i pass there? In the example is it JCoDestinationManager.getDestination("ABAP_AS_WITHOUT_POOL"); but then i get the error: ""(106) JCO_ERROR_RESOURCE: Destination ABAP_AS_WITHOUT_POOL could not be created:"..

Can anyone explain me how this works?

 

Thanks in advance!
