Forte recommends not using DOM for 'documents with large

(TechNote 11811) so I am using SAX.
Any thoughts/suggestions would be welcome,

Hi Laks
Here is an example of converting a XML doc to a DOM object.
The method is ParseXML(pXMLString:TextData, pListType:CSAListInterface).

Re: (forte-users) SAXParser and InputSource

Hello,
I was wondering if anyone has any experience using the XMLParser
Library!? in Forte. I have no problem parsing a file using the
forte parser but when I try to parse a message/TextData object I get
the error " element not found " ( which is not due to my xml file )
The class InputSource has a method that takes SeekStream in its
setCharacterStream method:
str : MemoryStream = new();
str.open(SP_AM_READ_WRITE);
str.WriteText(myMessage);
theSource : InputSource = new();
theSource.setCharacterStream(str);
myParser.parse(theSource);Add this line after you're done writing to the MemoryStream:
str.Seek(position=0);
When the SAX parser is reading, it's reading from the current position
forward; after writing to the stream the current position is at the
end, so you have to rewind it to the beginning before giving it to the
SAX parser.

Why not this:

myText.ReplaceRange('-', myText.Offset, myText.Offset+1);

or if you prefer verbosity:
while myText.moveToString(source=' ') do
myText.ReplaceRange(source='-', startOffset=myText.Offset,
endOffset=myText.Offset+1);

Re: (forte-users) Fusion for the VAR

Hi,
It is a good idea. In fact, I think that how Forte is
going to integrate her own suite of app. too. ( I
kind of recall that there is a speech on this topic in
Forum ).
However, as Forte will most likely goes toward Java, I
would suggest that you take into account the
abstraction on Conductor ( which is frankly an event
broker ) and Fusion ( which handles the XML mapping )
too. In doing so, you can save guard your investment
on the design without binding tightly with FORTE and I
bet there will be tons of event broker or XML parser
in the future market.
On the other hand, this integration by Fusion would be
perfect for a perfect world. But, in this imperfect
world, it would be hard to do cross-checking between
apps in Fusion.
In the old days, we repulicate data or do file
transfer to integrate apps. In doing so, we also
build-in all the cross-checking procedure / reports.
In the case of Fusion, is there such a safety net to
save guard data integrity. Can I identify a lost
event and trace back to find out whether it is a app.
problem or Conductor problem?
I think the customer would surely like to know.
Regards,
Peter Sham.

Fusion has been positioned as an EAI tool, something
at which it appears to
be very, very good, but in recent months I have been
thinking about its
possible role as an architectural tool for those of
us who build large,
multi-application suites of applications. Having
been tossing some of
these ideas around the halls at Harrison Street, I
thought I would try some
of them on this audience as well to see what
reaction I got.
This concept is based on the context that one has
multiple interacting
applications which are loosely coupled, or at least
which should be. E.g.,
an order processing application may need credit
status information from an
accounts receivable application and may generate
invoices which then need
to be tracked for payment by that application, but
the connections between
these applications are specific, limited, and
readily enumerable. Mind
you, people don't always build their applications so
cleanly modularized,
but I think we all agree these days that they should
be.
The idea is to provide each application with a
specific API, which it may
currently have only indirectly. I.e., today one
might simply have calls
directly from one application to another, but one
would gather all these
links together and define an API, probably in XML
which covered all of the
necessary communciations between applications.
These would then be used to
build a Fusion Proxy and one would build the
necessary Conductor processes
to handle the communications which previously might
have been made directly
between applications. There is probably some
performance loss in this
process, but many of these interfaces are not
performance intensive and my
bet is that if the whole Fusion concept has adequate
performance for the
purposes for which it is being primarily marketed,
then it has the
performance for this sort of usage.
One would get several advantages from this
structure:
1) Interapplication communications would be handled
by a Conductor process
and thus be much more readily configurable than any
hard-coded link.
2) One would gain the ability to unplug one's own
application and plug in a
customer's application when the customer insisted on
using something else.
3) The discipline of working in this structure would
insure clean boundries
between applications, which is not only sound
design, but promotes the
flexibility of the overall suite.
4) Those with untransitioned legacy applications
would have a framework
that would allow a mixture of new and old
applications to co-exist, thus
providing them with a transition strategy until the
full product line was
converted.
Note that I am assuming that one would want to build
the individual
applications so that they also used Conductor for
managing their business
process logic, but that seems to me to be an
independent decision from this
one.
So, comments?
Any downsides?
Any added benefits I haven't covered here?
Are there many out there that would benefit from
this approach or just a few?
Is anyone doing anything like this?
Note that the one downside I have found so far is
that Fusion licensing,
independent of the Conductor aspect, is based on the
number of proxies and
so someone like CI who has 15 or more applications
in a typical site is
going to have 15 or more proxies. My bet is that
this can be handled once
it is clear that use of Fusion by a VAR for
integrating own applications is
not the same use as by an end-user integrating
arbitrary multiple applications.

Sax parser problem

hi,
i am assuming the problem is with sax parser but i cant be sure. I am parsing a xml file (about 1.4MB) with some data in it. the parser i have created reads the xml file correctly for the most part but when at some point the
"public void characters(char buf[], int offset, int len) throws SAXException"
function stops working correctly....i.e it doesnt fully read read the data between the "<start>" and "</start>" element. say it reads about 100 id's correctly---for 101 ID it does this. This is just an example. Since, the problem might be with how :
"public void characters(char buf[], int offset, int len) throws SAXException"
function is reading the data i was wondering if anybody else had encountered this problem or please let me know if i need to change something in the code: here's a part of the code :

I haven't gone through your code but I also had a similar error....and the exception in my was because of an "&" instead of the entity reference & in one of the element values. I use a non-validating parser but if you use a validating one then this might not be the reason for your exception.

Re: (forte-users) Minimal Fusion

Thomas,
A response which may contain no answers...and may lead to more questions...
As a novice fusion user, one of the largest obstacles to using Fusion is the lack of XML API's in an application, be it a customer's in-house or vendor's software product. Corresponding to this is simply the lack of any API's in the application. As Forte (abet Sun, now iPlanet) says in their training manual 'A nontrivial task is to build new adapters for your programs if you wish to enable them to interact using XML documents over HTTP'. This is probably an understatement.
The question that come to mind is:
Does the warehouse have published API's their product?
If not, then, IMHO, you have steep hill to climb, not the least being communication, cooperation, and coordination from the warehouse vendor (another one of those 'nontrivial tasks') in trying to create the required API's
if so, then it is a matter of building an adapter, in a language that is compatible with the warehouse's API (hopefully C or some derivation of) , that contains (1) a DOM (Document Object Module) to API Translator, (2) an XML Parser (converts XML to DOM and visa-versa) , and (3) a HTTP server (again, another one of those 'nontrivial tasks').
Forte (abet Sun, now iPlanet) suggests, and I would concur (with reservations), that if you haven't done this before you should probably hire their services from the Forte Integration Services group. Their costs (admittible high) should be offset be the time it would take to develop one on your own. A side benefit is working with them, you learn the process for making other adapters in the future. If Fusion is a marketing success, then the benefits should out weigh the costs.

As to your question "Is it reasonable to consider doing this project under Fusion as a
getting-feet-wet experience?" If you (or your customer) can afford the costs, and the warehouse has published API's, I would say that you gotta get-your-feet-wet somehow. If the warehouse doesn't have published API's and are not willing to put forth the effort and resources to do so, I would say your chances of success are considerably less.
In any case, IMHO, it will be a 'non trivial' undertaking.

"Thomas Mercer-Hursh, Ph.D." <thomascintegrity.com> 10/31/00 04:49PM >>>This may be one of those questions which has no answer, but ...
Our long term plan is to develop XML APIs to each of the modules in our
suite of non-Forte applications and to integrate these under Fusion, thus
gaining Conductor management of the inter-module work flows and a cleaner
loose coupling of the applications along with other benefits such as the
ease of integration with other packages, a clean way to migrate to Forte
modules, and an ease of interconnecting "mini-applications" to address
specific customer needs.
I have an existing customer who has made a decision to migrate to a third
party warehouse from an in-house warehouse. I.e., were this transition to
the new structure complete, this would correspond to unhooking some of our
modules and replacing these with an adapter to the corresponding modules in
the third party warehouse.
In fact, as it looks now, I will need to build the logical equivalent of
these APIs anyway -- might as well do it in XML, right? And these APIs
will communicate with a daemon responsible for the message traffic to and
from. I tried to get this traffic to be XML and to use MQSeries or JMS as
the transport, but the folks at the warehouse end don't seem to be able to
handle such things, so I am stuck doing something fairly stupid for the
actual communication.
So, the question for those out there who have already paid their Fusion
dues, is it reasonable to consider doing this project under Fusion as a
getting-feet-wet experience. There are only half a dozen APIs to do and I
have to do those anyway and am inclined to make them XML regardless. There
will be one communication daemon to which all these connect and the
business processes originally implemented in Conductor will basically be
just point to point connects, except for routing traffic from the daemon to
the right API based on message type. That's really all I need it to do,
i.e., far too simple to actually need Fusion, but a possible opportunity
to get started and then to expand to other uses.
Crazy?

As a novice fusion user, one of the largest obstacles to using Fusion is
the lack of XML API's in an application, be it a customer's in-house or
vendor's software product.In this case, the good news is that one of the applications in question is
our own, so whipping up an XML API to suit each required transaction on
that side is no more, probably less, work than importing or exporting a
flat file or whatever. Moreover, my current expectation of how this
interaction will work is something like this:
</pre>
---Fusion------
| |
WACS<-->WACS_Daemon<----VPN socket
connection---->IS_Daemon I/S
</pre>
I.e., I/S, our application, and the IS_Daemon which handles the connection
traffic across the internet link are both mine. For I/S, I will create XML
APIs to suit. For the IS_daemon, I might use the transform facilities to
convert this XML to the pipe-delimited format they are expected at the
other end and make the daemon a simple manager of the connection or, the
daemon could do the conversion, but the former seems like the more
appropriate approach. The API between the two daemons is something we are
defining now (unfortunately I lost the argument to make that XML).
Corresponding to this is simply the lack of any API's in the
application. As Forte (abet Sun, now iPlanet) says in their training
manual 'A nontrivial task is to build new adapters for your programs if
you wish to enable them to interact using XML documents over HTTP'.My neophyte understanding is that, since I am defining the API to I/S in
the diagram above and I can make this XML, then the adapter issue
disappears there. I might have to create an adapter for the daemon, but if
necessary, I could make that the same XML on a pass through and do the
translation in the daemon.
If not, then, IMHO, you have steep hill to climb, not the least being
communication, cooperation, and coordination from the warehouse vendor
(another one of those 'nontrivial tasks') in trying to create the required
API'sWe are well through this process anyway. ... which is not to say that it
has been or will be easy, but it must be done whether I use Fusion or
not. Given that the vote has gone in favor of simple messages of
pipe-delimited records, i.e., basically flat file, the technical issues
there are minimal.
if so, then it is a matter of building an adapter, in a language that is
compatible with the warehouse's API (hopefully C or some derivation of) ,
that contains (1) a DOM (Document Object Module) to API Translator, (2)
an XML Parser (converts XML to DOM and visa-versa) , and (3) a HTTP server
(again, another one of those 'nontrivial tasks').I'm not sure I quite understand what you are saying here. The HTTP part
won't be there since we will apparently be connecting via a VPN sockets
connection. But, how are you distinguishing DOM and XML since DOM is a
particular form of XML? The XML API I build for I/S will be DOM compliant.
Forte (abet Sun, now iPlanet) suggests, and I would concur (with
reservations), that if you haven't done this before you should probably
hire their services from the Forte Integration Services group. Their
costs (admittible high) should be offset be the time it would take to
develop one on your own. A side benefit is working with them, you learn
the process for making other adapters in the future. If Fusion is a
marketing success, then the benefits should out weigh the costs.I am familiar with the "party" line. If I were building a complete
interface to another major product (I/S is roughly equivalent to JDEC in
coverage) in the context of an EAI project, I would happily invite them in
and hope to pick up pointers. Here, though, there are only 8 or 9 total
transaction types and either all of the interfaces are XML, i.e., no
adapter required as I understand it, or only the daemon will need an
adapter and that will be a choice I can make depending on how things
go. One does wish it were possible to sample a small piece of that
knowledge store without having to buy the whole thing, though.
The Forte Integration Services group markets, or will market, a Fusion
Adapter Designer, some sort of a SDK, which assists in the creation of
Adapters. I do not know the availability of that product at this time.Last I checked, one couldn't get this without the consulting ... hence the
last sentence above.
Thanks for your input.

SAX parser problem in JDK1.5

I have parse the xml file using SAX in jdk1.5 environment. During the parsing, it missed the some text content.
for example

</employeeid>
If i have parse the above xml file using SAX in jdk1.5 environment. The output is
1001
100
during the parsing , SAX parser misses digit of 2.
if i have parse the above xml file using SAX in jdk1.4 environment , it is working fine.
what is the problem in jdk1.5
please help
bala

What I expect the problem to be was discussed recently in a topic titled "SAX Parser Problems" that was started on March 14 at 6:59 AM by JackoBS.
Read that and see if it fixes your problem. If so, it is not a JDK1.5 problem, but a user error.

Oggetto: Re: (forte-users) XML - ExportDocumentproblem

Ok, I'll detail the question.
The application I'm talking about is a Fortè server and a Java client (or other
client platform).
I have to send via HTTP a XML message to and from the two.
I'm developing the Forte side (but think will have the same problems in Java).
Since there could be lots of client sides developed by others teams (or given
out to external suppliers) my concern is to send the message containing the DTD
information to enforce the validation on the various application.
Maybe you are right and I'm overcautious, but the messages are to be built
following the various DTDs (and this is impossible aside starting from a xml
template, since I cannot create a DTD runtime or insert a declaration <!DOCUMENT
...> ... I'll example:)
doc : document = new();
xml : processistruction = doc.createprocessistruction('xml version="1.0"');
root : element = doc.createelement('root');
dtd : ????? = doc.create??????(???);
doc.addchild(xml);
doc.appendchild(dtd);
doc.addchild(root);
All would be nice if I only know how to fill the ???
This is needed because I want to use the parser to make the work for me and
check the doc while I build it.
Also since the DTD should be put on a url it could change and I need to send
this info along with the message to inform the client (since I'm the server
[suffering of multiple personality problem] I think is my duty).
If I recall well DTD are meant to force the parser to create defaults and things
like that.
As I said I'm new of the problem and probabli I may use DTD in a wrong way, but

Subject: RE: (forte-users) dynamic select & maxrows parameter
Think there's a mis-understanding. The maxrows I refer to is not SQL but a
forte method parameter as in the following:
dynStatement = self.DefaultDBSession.Prepare(commandString = sqlStatement
,inputDataSet = inputDescriptor
,cmdType = commandType);
rowType = self.DefaultDBSession.Select(statementHandle = dynStatement
,inputDataSet = inputDescriptor
,resultDataSet = outputDescriptor
,maxrows = 100);
the variable sqlStatement holds the "dynamic" select string.
If I don't set maxrows I get a runtime error, as mentioned, it is running
against Oracle.
At 14:47 10/12/99 +1100, you wrote:
We use Oracle and Rdb and we have dynamic and non-dynamic SQL. No
combination of
these demand a max rows clause.
For example the following query works on both databases :
lvLanguageCodesList : Array of LanguageCodes = new();
begin transaction
sql select Language_Code LanguageCode,
Language_Nm LanguageNm,
System_Control_YN SystemControlYN,
Other_Language_YN OtherLanguageYN
into :lvLanguageCodesList
from SRD_LANGUAGE_CODES
order by Language_Nm
on session StudentRegistryDBSession;
end transaction;
if lvLanguageCodesList.items = 0 then
return Nil;
else
return lvLanguageCodesList;
end if;
Indeed if we wanted to use max rows its a bit of a pain in the bum because
Oracle and
Rdb use different syntax to define the row limit. So our dynamic SQL
'builder class'
has to detect the database flavour and configure max rows accordingly(where
we want to use
it).
I can only guess that the error you are getting is not assoicated to therow
limit or is caused because of the database you are using ?

against Oracle.
At 14:47 10/12/99 +1100, you wrote:
We use Oracle and Rdb and we have dynamic and non-dynamic SQL. No
combination of
these demand a max rows clause.
For example the following query works on both databases :
lvLanguageCodesList : Array of LanguageCodes = new();
begin transaction
sql select Language_Code LanguageCode,
Language_Nm LanguageNm,
System_Control_YN SystemControlYN,
Other_Language_YN OtherLanguageYN
into :lvLanguageCodesList
from SRD_LANGUAGE_CODES
order by Language_Nm
on session StudentRegistryDBSession;
end transaction;
if lvLanguageCodesList.items = 0 then
return Nil;
else
return lvLanguageCodesList;
end if;
Indeed if we wanted to use max rows its a bit of a pain in the bum because
Oracle and
Rdb use different syntax to define the row limit. So our dynamic SQL
'builder class'
has to detect the database flavour and configure max rows accordingly(where
we want to use
it).
I can only guess that the error you are getting is not assoicated to therow
limit or is caused because of the database you are using ?

Subject: (forte-users) dynamic select & maxrows parameter
the help for DBSession.Select method says that the maxrows
parameter is not
required. Leaving it out does not give a compile error.
However at runtime
an error is got saying maxrows must be > 0.
I am using a method that accepts a where clause as a
parameter and am not
really interested in what the number of rows will be.
Should I be?
Does anyone have any knowledge they can share on this one.
Thanks.

Re: (forte-users) Hi - Query on XML Import document -Hang

Double check that your XML is valid. I've seen
importDocument hang when I'm missing an end tag.
I don't think it's a validating parser.
Of course, there's no documentation, so.... :)

Hi guys,
I am trying to import an XML document from a
Memory stream object. I
got the example
from this group ( It was very helpful ).
Sample Code :
l_MemStr : MemoryStream = new;
l_MemStr.Open( SP_AM_READ_WRITE );
l_MemStr.WriteText( source = l_XMLData );
l_MemStr.Seek( position=0 );
-- Create a Document object from the memory stream
myDoc : Document = new;
myDoc.importdocument( l_MemStr );
After this line nothing seems to happen.. the
partition just hangs... keeps
the CPU busy.
If i deploy the same in a NT or on a IBM box it
works fine. The problem is
with the Sequent box..( i guess ).
Did any of you guys face a problem like this...
Please let us know..
I would really appreciate it.
Thanks

Well, Forte have agreed to release a patch for the XML bug on DG Unix with
Forte Version 3.0.M.2. I've attached a related mail with this.

I did check the xml by opening it in IE 5.0 for it's well-formedness. Still
it's failing on sequent box.

Well not really. One way to check if the xml is valid is to open it in IE
5.0. If its well formed then it will show up otherwise it will give you an
error. Also the document object is not the best code that came out of Forte
and has errors, so this might be a bug you will have to report. And they
are not giving any new patches until 3.5 comes out in 2 months.

If the XML is invalid it should fail on all boxes. This should be a sequent
specific problem.

Another SAX Parser Question

Hi All,
I get an xml file by making an http request. The name of the DTD comes as a relative path in the response xml file.
Questions
1. Is there a way to handle this
2. I read somewhere that i could avoid looking at the DTD alltogether,
can someone show me how with a sample code.
Kind regards

Nothing seems to help, Please help,
Im using jdk1.4 A full source codee would be great.
Thanks in advance.
This is the trace and the Code follows below:
