RE: cfmx and CAPTCHA
Hi All,
After having read through everyones posts here is how I actually did it
and its currently running today on a site that gets 2000 new
registrations a day. BTW this will run on CF 4.5 and up:
Create a Java CFX which randomly uses a True Type Font from a zip file
and randomly picks 6 characters to be displayed in a JPEG file. It
writes the image fiel to the filesystem so you can display it on the
page. It also returns (as a coldfusion variable) the six characters that
it has chosen to put in the image. eg.
You then immediately hash the contents of the variable and place it in a
hidden form field
Then have an input box for the users to type into
And finally on the page the form posts to you compare the hidden form
field value 'hashcode' to the hash value of whatever the user entered.
If this is the same then they entered the string correctly
if( hash( form_ivchars ) EQ form_hashcode ){
success = 1;
}
And there you have it. I'll have a word with the powers that be and see
if I can give the source code out. Please don't get your hopes up
though.

Subject: cfmx and CAPTCHA
Hi All,
How would one provide a cfmx-only solution (no .Net) for a
'CAPTCHA' solution. Any ideas would be appreciated.

RE: JAI Image resize gives rubbish images.
Hi Stephen, To increase the quality of the images you need to add a new JPEGEncodeParam: Add this before your ParameterBlock() and before the JAI.create(). JPEGEncodeParam encodeParam = new JPEGEncodeParam(); encodeParam.setQuality(quality); Where quality is a float. I belive 0.0 is crap and 1 is great, can't remember though. Adam. -Original Message- From: Stephen Moretti [mailto:[EMAIL PROTECTED] Sent: 17 February 2004 14:28 To: CF-Talk Subject: JAI Image resize gives rubbish images. Reading Java classes and methods and trying to work out how they all work and what I should be using has given me a permanent headache, so I hope someone out there can help. I've used and got working Matt Liota's ImageUtils cfc example/article. http://www.evolt.org/article/Image_Manipulation_with_CFMX_and_JAI/18/33907/ Only trouble is the thumbnails it generates are of less that great quality.

Complex Data Types in CF Websevice
Hi All, I'm having problems trying to consume a CFMX 6.1 Struct with a .NET SOAP Client. Here is my very simple cfc: Both of the methods work fine and I'm getting data back to my .NET SOAP Client its just that I cannot convert the returned structure content to anything useful. The problem is that in the WSDL generated by CFMX it defines a custom type "Map". I have tried casting this as a hashtable,Idictionary and a host of other things in C# but it doesn't work. Does anybody know what this "Map" object is and how I can decode it? Adam [Todays Threads] [This Message] [Subscription] [Fast Unsubscribe] [User Settings]
RE: cfexecute on unix
Hi Hugo, I had the same thought and the same issues with it.

RE: Novell to acquire SUSE
Redhat are not ending their free distros in fact they are extending the free distro into a new release called Fedora. See http://fedora.redhat.com.

RE: CFMX Instances on JRUN
Hi Joe, > I am unable to access the CFMX administrator with different port numbers. > i.e. > http://127.0.0.1:8300/CFIDE/administrator/index.cfm > http://127.0.0.1:8101/CFIDE/administrator/index.cfm When you use the default J2EE install and you tell it to connect to the webserver what happens is that it installs the CFIDE in webroot>/CFIDE/. So you will be able to access /CFIDE/. You will find that it has installed the CFIDE directory structure in: //CFIDE But there will be no .cfm pages in there. What you need to do is take a copy of the CFIDE from webroot>/CFIDE/ and place them in / root>/CFIDE which should be: /opt/jrun4/servers/cfusion-ear/cfusion-war/cfusion/ Now remove the /CFIDE/. You will also find that if you connected your first instance to Apache on installtion that the internal web server will not be running for your first instance. You can start that from: Jrun Admin Console -> -> Services -> WebService Just click the run button. Now you should be able to access both of the coldfusion administrators individually by using: ://CFIDE/administrator/index.cfm You will also need to remove the web connector and re-attach it to the cluster you created in JRUN that points to both of your instances. Remove by using: java -jar wsconfig.jar -uninstall -v Restart apache. Re-connect by editing the cfmxconnectors.sh in /opt/jrun4/bin and changing the line with the server in to cluster: So this: $CF_DIR/runtime/jre/bin/java -Dtrace.ci=1 -jar $CF_DIR/lib/wsconfig.jar -server cfusion -ws apache -dir /usr/local/apache/conf -bin /usr/local/apache/bi n/httpd -script /usr/local/apache/bin/apachectl -map .jsp,.jws -coldfusion -v Becomes: $CF_DIR/runtime/jre/bin/java -Dtrace.ci=1 -jar $CF_DIR/lib/wsconfig.jar -cluster mycluster -ws apache -dir /usr/local/apache/conf -bin /usr/local/apache/bi n/httpd -script /usr/local/apache/bin/apachectl -map .jsp,.jws -coldfusion -v Execute the cfmxconnectors.sh as root and check the /opt/jrun4/ConnectorInstall0.txt for any errors. If that was successful, stop and start all your cfusion server instances from the JRUN admin console and they will find each other. The event logs will show this as they are now clustered. You can now place content in your /usr/local/apache/htdocs directory and have your pages accessed by both instances. Bear in mind that by default JRUN uses sticky sessions so that if you are testing from a single machine/browser you will most likely only see one instance processing anything. You can tun off sticky sessions but I would only recommend this if you do not want to share session data between the instances because when you make a request to one server it stores your session data in ram and when you immediately hit the next server it sync's all your session info. Thus drastically slowing down the server. I hope this help (and I hope I didn't miss anything), Adam Hope. [Todays Threads] [This Message] [Subscription] [Fast Unsubscribe] [User Settings]

Please help with apache connector CFMX 6.1
Hi All, I'm having problems getting Apache to pass the .cfm templates to CFMX. I have run the cfmx-connectors.sh shell script int /opt/jrun4/bin directory and it completes successfully with no errors. It modifed the apache/conf/httpd.conf file successfully as well and the mod_jrun.so file is successfully built in the /opt/jrun4/lib/wsconfig/1 directory. However when I browse /CFIDE/administrator/index.cfm it just displays the encrypted coldfusion template as plain text. It isn't handed over to Cf to process. As far as I can see everything is setup correctly even the jrunserver.store file points at the right port. I can access the administrator fine by going to :8101/cfusion/CFIDE/administrator/index.cfm so the deployment has worked. I just can't access it through apache. System config: CMFX 6.1 deployed as EAR onto bundled JRUN4 Apache 1.3.27 Solaris 8 Adam. ~| Archives: http://www.houseoffusion.com/lists.cfm?link=t:4 Subscription: http://www.houseoffusion.com/lists.cfm?link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 This list and all House of Fusion resources hosted by CFHosting.com.

RE: Search Engines
Hi Ryan, We used to use verity but when we started indexing over 3million files it got very slow indeed. We now use lucene to index flat files and database content. If you are a java coder you can write your own cfx interface to lucene and then anything you can access with java you can index with lucene. It seems a daunting task at first but once you get your head around how lucene works its really easy. To give you an idea of speed we index over 90,000 flat files in one index and the search takes about 140ms on a Sun E250. (dual proc 300mhz 1gb ram). The indexing is also far quicker.

RE: PCodeRuntimeContextImp::executeSQLTagCFQuery::endTag and other weird errors
Hi Andres, Take a look at this document at MM about Locking Best Practices: http://www.macromedia.com/v1/handlers/index.cfm?id=20370&method=full That should give you a guide on how to implement good locking in your code. If you want to track down an elusive lock then on a development server enable "Automatic Read Locking" for all the scopes in the Coldfusion Administrator Locking section. This performs full write locking checks as well and wiil halt your code when it finds unlocked writes.
