Re: JDBCR4:Can't connect,not sure how to get full java error text

Hi Tony,

A quick Google turns up the following Microsoft page:
http://support.microsoft.com/kb/826080

I'm not sure if that page directly relates or not, but it does tell me the following:

a) SQL Server has an option that forces SSL for all clients (Whether they enable it or not.)

b) There have been bugs in that support for Type 4 JDBC drivers (which is what you're using) in the past, and that there's a fix for it.

You may already have that fix, and you simply don't have SSL set up on the server side, I don't know.. But maybe it'll get you hopping along the right path (sorry, it's Easter tomorrow, so I had to use that sort of wording.)

But I am not sure why it would be using SSL... I am not specifying SSL, but
maybe that is a requirement. Is this telling me that I am missing a
protocol driver?

Good Afternoon!

I have started using Scott Klement's JDBCR4 service program to connect to
an SQL server, and I have a quick question. First of all, I would like to
thank Scott for this service program and the documentation. Integrating DB2
with other DB platforms is becoming the core challenge at my shop, and this
will greatly simplify accessing all data from the iSeries. I am trying to
connect to an MS SQL 2000 server (see source below).

d/copy carollat/jdbcr,jdbc_h
d LynxConn s like(Connection)
d UserName s 50a inz
d Password s 50a inz
/free
*inlr = *on;
UserName='username';
Password='password';
LynxConn=JDBC_Connect('com.microsoft.sqlserver.jdbc.SQLServerDriver
'
:'jdbc:sqlserver://10.10.4.22:1433'
:%trim(UserName)
:%trim(Password));
if LynxConn=*Null;
dump(A);
endif;
return;
/end-free

When I run the program the first time, I get a JVAB56D message in my job
log (Java Virtual Machine is Classic.). Then, I get a screen like this:

_____________________________________________________________________

and then I get the following error:

The driver could not establish a secure connection to SQL Server by using
SecureJNI_CHECKERROR Ø Xë « Ø ­ÏFs

I have some java experience, and if I could just see the top the java
error message, I could at least have something to go on. But the screen
above is input inhibited the entire time it is shown (can't scroll "up"!),
and the dump just shows the stuff in the RPG program. I have tried using
the 'JDBC_ConnProp()' method also, and with the same result (what I can see
of the result anyway).

So my question is, first of all, to anyone who uses this service program
(or Scott, if he has time 8)), can you see anything wrong with the
connection attempt, assuming the IP and user/pwd are valid, and the java
odbc driver is installed correctly? Or to anyone who uses java with RPG,
how can I view the entire java error message. Thanks in advance!
