use the Report() class. Where can this class be found?

column "does not exist"

manley — Wed, 09 Mar 2005 17:17:48 -0000

I am dragging a column from the Field Browser into the report, and
an exception is thrown. Any idea why?

java.lang.IllegalArgumentException: The column
AST_OWNER.LAE_GEO_MASTER.GEO_ID does not exist in the
data
source.

Cannot open database tables

saifi26 — Sun, 23 Jan 2005 00:41:50 -0000

I was trying to connect to my sql server database
throught ativav jdbc driver .. and it doesnt show me the
database tables. Instead it shows me generic
INFORMATION_SCHEMA tables in the list. I am trying to
connect to localhost. I tried the same thing at my office
computer and connected to our database server and it
worked. The connection information is as follows:

driver class name: net.avenir.jdbc3.Driver

connection info: jdbc:avenirDriver://localhost

dbase:eEMS

username: sa

password:

Please not that it does connect to the server but just
doesnt show the database tables in the All database
fields list.

Thanks

Creating PDF on the flights

aleli — Thu, 27 May 2004 16:19:06 -0000

I am trying to create a report for each individual in a
company that has opened support records and later
export to pdf.
I also need to create a report containing all the open
records for the company (but this is no problem, since I
created (pre-defined) a report in datavision for each
company(user coordinator)).

But I do not know how to create the reports for each
individual. I do not want to add a new report in
datavision each time a new (different) user opens a
report.
Can I create the output report for each individual on the
flight?.
Later I need to email a pdf to each general individual and
to the company coordinator

Thanks,
Aleli

the feature "group by user columns"

mammalian — Sun, 24 Aug 2003 07:32:49 -0000

Hi Jim!
It seems that datavision would support group by user
columns since 0.5.3 according to your respond to
feature request, but i can't know how to use this
feature.

make Database abstract !

Stefan Hansel — Mon, 14 Oct 2002 16:50:41 -0000

that would be a great deal.

Currently I have the problem, that I want to integrate
Datavision-classes into a very strict other Framework
which I have to use.

This framework already has a full set of DB-classes and
is already initialized by various means (jdbc-driver,
name, password etc.)
As a programmer I am not allowed to ask for passwords
of the running-server of course and thus have no means
to get the information about it over this framework and
the classes, BUT

the framework is so nice, to return a readyForUse
Connection-Class.
And that's definitely all what your Report-Framework
(without Swing-GUI) needs ...

currently I wrote a class that extends your Database-
class.
All I had to do was to override the initializeConnection()
method.

You may ask: where is the problem - if you extended
the class, than everything should be just fine.

Unfortunataly not:

Of course my own constructor has it's own variables for
the class, which want to be saved in private members !
Your class doesn't own a standard-constructor (not even
protected), which forces me to call your constructor with
empty variables at first (JAVA forces me to call super()
as the first thing in a constructor)

And here begins the problem:
Your constructor already calls initializeConnection().
That's fine, because my overridden code is called,
BUT ... my own constructor couldn't finish so far to
initialize all variables, that initializeConnection already
needs !

I solved the problem the following way to have it work in
my environment, but it is merely a hack - an abstract
baseclass for Database would be the better solution !

This is just a dummy of how my code looks like now :(( :

public class MyDatabase extends Database {
// my variables ...
DBManager myDbMan;
boolean fullInitialized=false; // hack

public MyDatabase(DBManager myDbMan, Report
report)
throws allYourEcxpetions {
super("","",report,"",""); // have to call it first :((

// initialize my Variables ..
this.myDbMan=myDbMan;
fullInitialized=true;

// and call again the other functions
initializeConnection();
loadAllTables();

}

public void initializeConnection()
throws allYourExceptions {

if (!fullInitialized) return; // hack

try {
conn=dbManager.getConnectionByDataSource
dataSourceName);
} catch (Exception e) {
errLg.logIt("MyDatabase.initializeConnection: couldn't
establish connection");
throw new IllegalAccessException();
}
}

Defining custom page size

Anonymous — Tue, 09 Jul 2002 08:20:03 -0000

We are able to define the types of pages but
userdefined page size is not supported .

so can somehow this be manipulated as i have a
special requirment to print report on a printed statioary
of odd size?

if anyone finds its solution plz reply me at
Ravi_indore@rediffmail.com

Thanks
