How can i login to a remote SAP NetWeaver 6.40 SR1 j2ee server?
I try this:
LoginContext vLContext = new LoginContext("SAP-J2EE-Engine", new ABSCallbackHanlder("id", "psw));
vLContext.login();
and this work fine if this run under the web container.
But if is used from a external client (on other machine), this exception occurs:
Caused by: java.lang.SecurityException: Unable to locate a login configuration
at com.sun.security.auth.login.ConfigFile.<init>(ConfigFile.java:97)
I have the jndi.properties in classpath.
Using JBoss the system properties "java.security.auth.login.config" must be set to the auth.conf file.
I think that for SAP i need to do it also, but i don't find this kind of configuration file.... Where i can find it?
Thank You
Roberto
ABSCallBackHanlder is:
public class ABSCallbackHanlder implements CallbackHandler
{
protected String iUserName;
protected String iUserPassword;
public ABSCallbackHanlder(String aUserName, String aUserPassword)
{
iUserName = aUserName;
iUserPassword = aUserPassword;
}
public void handle(Callback[] callbacks) throws IOException, UnsupportedCallbackException
{
for (int i = 0; i < callbacks.length; i++)
{
if (callbacks<i> instanceof TextOutputCallback)
{
TextOutputCallback toc = (TextOutputCallback) callbacks<i>;
switch (toc.getMessageType())
{
case TextOutputCallback.INFORMATION :
System.out.println(toc.getMessage());
break;
case TextOutputCallback.ERROR :
System.out.println("ERROR: " + toc.getMessage());
break;
case TextOutputCallback.WARNING :
System.out.println("WARNING: " + toc.getMessage());
break;
default :
throw new IOException("Unsupported message type: " + toc.getMessageType());
}
}
else if (callbacks<i> instanceof NameCallback)
{
NameCallback nc = (NameCallback) callbacks<i>;
nc.setName(iUserName);
}
else if (callbacks<i> instanceof PasswordCallback)
{
PasswordCallback pc = (PasswordCallback) callbacks<i>;
pc.setPassword(iUserPassword.toCharArray());
}
else
{
throw new UnsupportedCallbackException(callbacks<i>, "Unrecognized Callback");
}
}
}
}
Hi Roberto,
AFAIK, to do a remote login you need to use the RemoteLoginContext instead of the pure JAAS LoginContext. For more details you can have a look at this page in the documentation: http://help.sap.com/saphelp_nw04/helpdata/en/ac/ce417acc9a4d48aa52fa562cb9b194/frameset.htm
Hope that helps!
