Hello Patrick,
The same thing you are trying to do here is already implemented in the
SessionBean class in 5250.
What you should do, I think (and we do it all the time in our ERP systems
based on our own Java Workflow framework for iSeries) is setup a cache of
authentications for the user. When he first tries to access a system by
name, you should get his profile from the cache (userid & password). If its
not there, you should popup you own dialog to ask for, try to authencitcate
the user by using the following code:
String user = dialog.getUserName();
String pwd = dialog.getPassword();
String host = "myhost";
AS400 as400 = new AS400(host);
as400.setGuiAvailable(false); // disables all password popping
as400.authenticate(user, pwd);
cache.put(name, new User(user.pwd);
When you need a 5250 connection, create a sessinbean, set its properties
and connect. Also set userid and password. Normally the bean allows you to
login automatically by keystroke simulation or by embedding the credentials
in the datastream (for the last to work your as400 must allow this by
setting the system value QRMTSIGN to *VERIFY). The property
bean.setSignonEmbedded() controls how the emulator does the auto signon.
Hope this helps,
Wim.

|
>-------------------------------------------------------------------------------------------------------------------------------|
Hi Guys,
It's been a long time, let's pump up the channel again :-)
I want to discuss the password-issues again.
As you all know we have to provide tn5250j or any jython
script we create with a valid password over and over again.
Since yesterday i finally saw you're able to provide the
AS400 class com.ibm.as400.access.AS400 with the
next statement to keep the password in cache.
AS400.setPasswordCache(1) --> in jython
AS400.setPasswordCache(true) --> in java
is the statement to let the jtopen toolkit store the
password in cache. So if we can change tn5250j
somewhat so that when we give username and
password for the first time (for example when we
provide the data for the first login-session) and then
imediately let jtopen open an iSeries connection and
also close it right away then we're sure the password
is in cache, which means that when we have to open
a new connection to the iSeries, that we simply can
use the next command to logon without the password
dialog popping up...
AS400("as400.stafa.nl", System.getProperty("user.name"))
On our systems, the user.name of the windows-box is
the same as the profile on the iSeries, but for other
users it should be possible to store the username in
a variable by the first logon-session. In other words,
if we should do it that way, and for example create a
variable that hold the username (read profilename) then
we could just use AS400("as400.stafa.nl", ProfileVar)
to open a connection to the iSeries and users are
happy cause they do not have to provide that freaking
password over and over again.
What do you guys think about that
The password needs only to be referenced once, when
we get the logonscreen for the first time and only then,
so there is no need to store the password into a variable
like we do for the username, cause the password is
stored in the cache we do not need a variable for it and
we are save again in the view of security, cause you're
not able to obtain the password in any way, except for
logging in with jtopen cause it stored that password in
cache the very first time.
If all this above is not clear, read it over and over again,
and just ask if something is unclear. If this all is possible
i get new power in mood again, cause i do not have to
worry anymore about users providing the password over
and over again, and we can focus on extending tn5250j
ever further, and programming java, jython and our iSeries
becomes fun again. Cause that was the only thing why
i always programmed my apps in VB.NET cause CA
stored the password in cache also, and you only had to
provide it once. So think about it and let me know.
Met vriendelijke groeten,
Best Regards,
