RE: JTDS (JDBC Driver) & JDBCR4 Connect String

Scott,

Thank you for your help. I'm a complete novice with Java. I'm saving your instructions for next time.

It turned out to be a signing on issue needing some more properties set in the jtds definition because of our local environment. The JDBCR4 subprocedures are working great and our proof of concept has moved past connecting to MS SQL and now waiting for a temporary license with the third party software.

Thanks again.

Jack,

The beginning of this stack dump is FAR FAR more useful than the end of
it... why did you only include the end?

If the problem is that it is scrolling past and you cannot stop it, then do this:

1) Start a fresh job
2) Type OVRPRTF FILE(STDOUT) TOFILE(QSYSPRT) HOLD(*YES)
3) Type OVRPRTF FILE(STDERR) TOFILE(QSYSPRT) HOLD(*YES)
4) Run your program that is failing
5) Sign off.

Now you should have the complete message in the spool. Please get the details from the START of the error dump and post them here so that we know what problem you're experiencing.

-SK

I'm trying to connect to MS SQL from RPGLE using Scott Klement's JDBCR4 service program. (Thank you! Scott. Have enjoyed your sessions at the last two RPG/DB2 Summit Conferences in beautiful suburban Lombard Illinois) I've been fighting this since Friday and hoping someone can help me login to the MS SQL database. I can connect using Microsoft SQL Server management Studio using it's driver and windows authentication (no password supplied) so I have the authorization. Got past the JVM & JDBC mismatch issue yesterday morning by getting a later JDK installed on the iSeries (7.1). I run this before calling the RPGLE that trying to connect:

ADDENVVAR ENVVAR(CLASSPATH)
VALUE('/QOpenSys/QIBM/ProdData/JavaVM/jdk71/32bit') REPLACE(*YES)

I call my program. JVM starts up with no error messages. Then I'm getting this:

net.sourceforge.jtds.jdbc.Driver.connect(Driver.java:184)

Login failed for user 'CFI\JPRUCHA'.

My application code, which calls JDBCR4 subprocedures, looks like this:


// Setup ClassPath before starting JVM

p_envval = getenv('CLASSPATH');
if (p_envval <> *null);
EnvVal = %str(p_envval);
endif;
if %scan('.:':EnvVal) = *zeros;
eval EnvVal = '.:' + EnvVal;
eval EnvValChanged = *on;
endif;
if %scan('/sqljdbc.jar':EnvVal) = *zeros;
eval EnvVal = EnvVal + ':/MSSQL/jtds-1.3.1.jar';
eval EnvValChanged = *on;
endif;
if EnvValChanged;
putenv('CLASSPATH=' + EnvVal);
endif;

UserId = 'CFI\JPRUCHA';
PassWrd = '########';

conn = JDBC_Connect('net.sourceforge.jtds.jdbc.Driver'
:'jdbc:jtds:sqlserver://T0B-DBMS03:1086'
+'/LaserRepository;'
+'instance=ISCR01'
: %Trim(UserId)
: %Trim(PassWrd));

if (conn = *NULL);
return;
endif;



The port is what the firewall setup is here but I've tried 1433 also. I've been all over the various Midrange listservs and everywhere else seeing different methods of setting up the Connect string. Am I doing something wrong here? Can someone supply a working example?

TIA
