Java Class Settings for new type

forums_noreply@adobe.com — Wed, 04 Oct 2006 23:33:10 GMT

Hi

I've modified the example SocketGateway to create a SilentSocketGateway.

I copied the original SocketGateway.java file and renamed it SilentSocketGateway.java. And modified the new file.

All I have done is commented out the two lines that say hello when you first connect and modified the main function names to be SIlentSocketGateway instead of SocketGateway. So not exactly rocket science in the JAVA programming stakes.

I haven't changed the package at the top of the java file.

I've compiled it (javac SilentSocketGateway.class) and run the class file into a JAR file (jar -cf SilentSocketGateway.jar SilentSocketGateway.class). I've copied the resulting JAR file to the C:\CFusionMX7\gateway\lib directory.

Restarted CF (on Windows obviously) and it finds the JAR because I can't delete it as its "in use"

But I can't install the new type, no matter what I type in the Java Class section of the new type I get a message saying

"Unable to find or load Gateway class examples.socket.SilentSocketGateway"

I've tried every variation of examples.socket.SilentSocketGateway I can think of. I've moved the java file, modified the package setting, all to no avail.

Can anyone help?

What should I be putting in the Java Class field of the new type?

Many thanks

run large file processing batches in scheduled task is failing

forums_noreply@adobe.com — Tue, 13 Oct 2009 10:06:09 GMT

We have a system that receieves real time messages via an event gateway. We file all these messages onto disk as small TXT files. I am trying to get our staging environment to load these TXT file overnight to bring staging back up to date with live. We are about 3 weeks behind at this point with about 45k messages a day.

We have a CFM page that gets a list of all the TXT files, reads each one in and then uses a set of CFC objects to create an object structure from the message (the message has various subcomponents/combinations) it then calls a serialise function on the object which serialises the object into a database, it passes the serialise call down to all the subcomponents.

This page seems to run fine if I run it manually. I can run blocks of 10k messages in comfortably as long as I'm willing to sit and watch it. This takes about an hour.

I wanted to schedule this page overnight so it would process the messages at 3am and thus be up to date by the time we came in about 8.

When I run the page as a scheduled task it gets to just over 1000 messages and crashes with a JVM out of memory error

Now I can't let this run as it also takes down the gateways that are responding to live messaging and while we can catch up its not really very practical.

I am resetting the object at the bottom of each loop using <CFSET msgObj = JavaCast("null","")> in the hope it wouldn't consume tons of memory, but obviously this isn't wokring. I am saving the scheduled task output to a file so I can see what happened but I don't really understand why its behaving so differently when i run it as a scheduled tasks to when i run the page in a browser,

Anyone have any pointers as to what i might try?

List currently executing pages or scheduled tasks

forums_noreply@adobe.com — Wed, 14 Oct 2009 07:38:28 GMT

I wondered if there was a way of executing a scheduled tasks, lets say every five minutes. But it needs to check that its not already running. i.e. that the previous execution has not taken longer than 5 mins.

I know that you can do lots of clever things with gateways but they don't do things serially and the order of execution is absolutely vital in this case.

This might be a way round an issue I hit in a previous post. http://forums.adobe.com/thread/505742?tstart=0

I figured I could process them in blocks of 500 every 5 mins. And just exit out if the previous block hadn't finished yet.

Any pointers as to where I might look?

many thanks

SQL Server DSN using a domain account to login

forums_noreply@adobe.com — Thu, 20 Aug 2009 14:21:30 GMT

This doesn't seem to work in CF8. If I use a SQL login it works fine but our production SQL servers dont use mixed mode security, its domain accounts or nothing. Does anyone have any idea how I can get a domain account set up at the CF end to use for the database login?

I need to do this per DSN as we run multiple apps on our CF server. So I can't just use the service account the CF server is running under. This is all down to the demands for "security" from our SQL DBA.

many thanks

Editor niggles

forums_noreply@adobe.com — Tue, 14 Jul 2009 10:15:17 GMT

Stupid things I know but...

You can't hit CTRL + RETURN to get a line break tag inserted, same for Paragraph tags and Bold, Underline or Italic. I edit lots of static documentation pages in amongst my CFML and being able to edit the text easily was pretty good in CFEclipse.

I couldn't figure out how to add keyboard commands the CFML editor through the Preferences dialog. Didn't seem to let me add things just edit the ones already present.

Its noce they are on the HTML toolbar but shortcuts to them are far faster. Any chance they can be added or get an instriction for how to add your own?

thanks

CGI scope not being initialised properly

forums_noreply@adobe.com — Fri, 28 Nov 2008 08:30:13 GMT

Something of an odd one here.

We run a version of the TCP/IP socket gateway on our boxes (CFMX7 and CFMX8) we recieve text packet messages from a remote server and send back acknowledgements.

Because we run this on several boxes we use an application.cfm to initialise various things, we use the CGI.SERVER_NAME to determine thesettings in the application.cfm by reading a config file and picking the right section, that way our code can be dropped onto any box, we just add a new section to the config file with the new machine name.

Yay config management!

Every now and again it dies and reports an error, we're talking maybe a half a dozen times a week out of the 250,000 messages its processing.

the error should report like this.

CONFIG ERROR: Unknown Server (gbstahosphlgw01) for application HL7 Messaging Gateway; TIME: 07:37 AM
APPLICATION.user_for_config:
CGI.SCRIPT_NAME: /hl7_gate/xml_from_ll/xml_listener.cfm
APPLICATION.this_server_name: gbstahosphlgw01

But they are in fact coming through like this.

CONFIG ERROR: Unknown Server (none) for application HL7 Messaging Gateway; TIME: 11:29 AM
APPLICATION.user_for_config:
CGI.SCRIPT_NAME: C:\Inetpub\wwwroot\hl7_gate\inbound_classics_STAR_LIVE.cfcC:\Inetpub\wwwroot\hl7_gate\inb ound_classics_STAR_LIVE.cfc
APPLICATION.this_server_name: gbstahosphlgw01

CONFIG ERROR: Unknown Server (none) for application HL7 Messaging Gateway; TIME: 01:04 PM

APPLICATION.this_server_name: gbstahosphlgw01

Anyone have any ideas?

SQL Server @@IDENTITY strangeness

forums_noreply@adobe.com — Tue, 25 Nov 2008 12:07:05 GMT

OK something changed in CF8. Either in the JDBC or the SQL Server drivers.

I have a lump of code that looks like this in a custom tag

<cfquery name="make_new_ref_id_qry" datasource="#ATTRIBUTES.dsn#">
INSERT INTO referral_tbl
(referral_type,
an_number,
account_number,
referral_status_code,
rejection_code)
VALUES
('INIT',
'#ATTRIBUTES.AN_number#',
'#ATTRIBUTES.account_number#',
'INIT',
0)
SELECT new_id = @@IDENTITY
</cfquery>
<CFSET rms_referral_id = make_new_ref_id_qry.new_id>

To get the new ID out. Now I'm changing this to be a stored proc that gives me the ID back cos I know this is really sloppy practise.

But this code has been running fine on our CFMX7 boxes, we've upgraded our dev boxes to CF8 and sometimes (not always) this code dies with the fllowing error being reported

Element NEW_ID is undefined in MAKE_NEW_REF_ID_QRY.

Now I want to know is there something I can change on the CF8 boxes that will make it easy for me to just upgrade the porduction boxes or do I have to trawl all my apps and code for this stuff and turn them into stored procs?

What changed?

Also does anyone have any idea, why it works sometimes?

I'd point out that the dev system and live system are in fact talking to the same database. So there's no difference on the SQL Server side of things.

many thanks

CFGRID HTML AJAX doesn't work in IE5.5

forums_noreply@adobe.com — Fri, 15 Feb 2008 10:38:55 GMT

It would seem there is a problem using an editable grid in IE5.5. If you use dropdowns as part of your editable HTML AJAX CFGRID.

To reproduce make a grid and set it as editable.

Set the values and valuesdisplay attributes on a gridcolumn and make the column selectable.

Now try and view the grid in IE 5.5.

You just get the dropdown for the slectable columna and a Javascript error. LIne 26 char 288 Object doesn't suport this property or method.

Stop the column being Selectable and its fine.

Make the column selectable but remove the values and valusdisplay attributes and its also fine for editing.

Sounds like a bug to me.

If anyone has any idea how to fix this. I'm guessing its buried in one of the many Javscript files that are loaded when using AJAX controls then I'd be very grateful.

many thanks

Flex Builder 2 not compiling or debugging?

forums_noreply@adobe.com — Sun, 22 Apr 2007 10:42:09 GMT

I have been working my way through the Flex 2 Training from the source book. I'm on a vista laptop and have run into problems compiling and debugging my projects (chapter 5). Whenever I try to debug I just get a browser window saying "Initializing" and not much else.

If I go and find the BIN directory of the project I can run the SWF directly or via the HTML and the updates are in place but it won't actually debug. Flash is reporting version 9.0.45.0 and really simple flex projects seem to compile and debug fine (a couple of buttons on screen) but the more complex projects just don't want to co-operate. I've tried it with both my own code and the sources from the book.

As I say they will run fine when I open them directly but not much use for debugging

Socket Gateway modifications

forums_noreply@adobe.com — Thu, 05 Oct 2006 12:56:44 GMT

Anyone have any ideas how I could change the control characters that the socket gateway uses. Its adding a character to the ACK message I am returning to another system. Its causing us some problems. I want to strip this last char off, i'd also like to change the end of message character as my messages are frequently chopped up because of stray CHR(13) values in the string I am being sent. I'm trapping this by stitching messages together until I receive the EOF marker but once again its a pain and not very efficient.

Many thanks

Steve
