Could not initialize class javax.media.jai.JAI
Hi everybody, A few days ago, one of our Web-sites that we have hosted by Yohost started display error: Could not initialize class javax.media.jai.JAI when ImagePaste() function is executed. The code was working for a long time. It still works correctly on my development server. This is CF8. Host guys cannot figure out what's going on. Does anybody have any insights on this error? We need to fix this ASAP. Thank you in advance.

Re: Problem with CF Execute
If this software requires a registration, like entering serial number or activation code, most likely, it uses Windows registry to remember it. When it starts up, it looks for this entry in registry, possibly in the profile of the current user. When you run the program from CF under SYSTEM account, that profile is not available. Therefore, your program exits, because it thinks it is not registered. Some ideas. (1) In CF Service options (Control Panel - Services-Properties) check box Allow service to interact with desktop. Restart CF service. Now, if you are on the server machine, you will be able to see that error message box that bips. (2) Run CF under account that you used to register the program. Will work, but not recommended. (3) It might be possible to re-register it under SYSTEM. For this, use (1) and CFEXECUTE the program in interactive mode (with GUI), while on the server computer. Enter the registration number, as needed. Try if it works. If it does, you can now uncheck the Interact with desktop checkbox. It will work in a normal way now. I think I might have narrowed the cause down to the account permissions. When I ran cmd.exe as the Local System account and tried to execute my command line arguments, I was actually able to see what the error dialog mentioned. The third party application doesn't think it's registered. So, I'm thinking this isn't a CF problem at all, but one with the Windows account permissions. Still don't know how to solve it, but that's what it looks like to me.

Re: scoping
From my [private] point of view, the scoping of 100% variables is a programming extremism. When some scope is implied, there is no reason to scope variables, unless it is absolutely necessary, like in CFQUERY-related loops, or using functions with side effect(s). Or if this is a policy of your organization (strange places may have strange rules). This is similar to requiring the use of parenthesizes in arithmetic expressions in all cases, instead of relying on defined functions precedence rules. Or to prohibit the use of a++, allowing only the use of a=a+1 in C code for readability reasons. Moreover, I always thought that for a default scope, there is no performance gain, if I use fully qualified references, because the default namespace is always checked first, regradless of what some people say that, if you don't use scoping, some overhead is aways involved. So, I wrote a simple test below. No functions, no CFCs, just plain page code: cfset a=1 cfset b=2 !--- This is how most people would write this --- cfset c=0 cfset stTime=GetTickCount() cfloop index=i from=1 to=10 cfset c=a+b /cfloop cfoutputNo scope: c=#c#, time=#GetTickCount()-stTime#br/cfoutput !--- This suppose to be more readable and safe --- cfset c=0 cfset stTime=GetTickCount() cfloop index=i from=1 to=10 cfset variables.c=variables.a+variables.b /cfloop cfoutputScope: c=#c#, time=#GetTickCount()-stTime#br/cfoutput I would expect exactly the same or, at least, very close results. But, results are so unexpected, that I was clicking the Refresh button of my browser for 10 minutes, like crazy. Non-scoped version ALWAYS runs 5-15 times FASTER than the scoped version! This is on CF8, 32-bit, 4 CPU Dell Server, Windows 2003. Could somebody run this on CF9 32/64 bit? Any ideas, how it can be? Remembering scope precedence rules in CF8, I wrote another test for a function with a side effect. Therefore, the explicit scoping of external references suppose to increase the performance. Right? So, this is the test: cffunction name=test1 cfset var i=0 cfset var stTime=GetTickCount() cfloop index=i from=1 to=10 cfset variables.c=a+b /cfloop cfoutputFunction no scope: #GetTickCount()-stTime#br/cfoutput /cffunction cffunction name=test2 cfset var i=0 cfset var stTime=GetTickCount() cfloop index=i from=1 to=10 cfset variables.c=variables.a+variables.b /cfloop cfoutputFunction scope: #GetTickCount()-stTime#br/cfoutput /cffunction cfset a=1 cfset b=2 cfset c=0 cfset test1() cfoutputc=#c#br/cfoutput cfset c=0 cfset test2() cfoutputc=#c#br/cfoutput Non-scoped version ALWAYS runs 2-3 times FASTER than the scoped one. So, at least on my server, the claim that scoping not only increases readability, but also gives a performance gain looks like not entirely accurate (c). So, scope as less, as you can??! ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:344818 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: cfhttp response with non-english characters gets cut off
I think, you gave up too early. This is how I would do this. Version 1. Use another tool to get the stuff from the server. Not a browser or cfhttp. It must be able to save your stream, as an unchanged byte stream without any conversion to a disk file. So the number in the Content-Length would exactly the same, as the length of the file. Don't want to advertise anything on this list. You can easily find such tools. After that you can conduct clean experiments using cffile. Obviously, this must be the case, when cfhttp truncates the data. stPos=1 cfloop - Use ASC() to find the first character with the code above 127, starting from stPos. cfloop - Go to some Web-site that has utf-8 table (like Wikipedia) and look whether this is a valid escape character. If not, break - it is not valid utf-8 stream. Report error to your provider. - Get the code of the next character. See, if this is an escape or data char. Consult the table above. Break with utf-8 error, as before, if sequence is not valid. - End this loop, if a data char was read. Continue, if an escape char was read. /cfloop utf-8 sequence is valid. Modify stPos to set it after the valid sequence. Continue. /cfloop utf-8 stream is valid. Report error here and to Adobe. Version 2 Enforce some 8-bit encoding in your cfhttp call, like iso-8859-1. Save result in a file using cffile with the same charset. This suppose to produce unchanged 8-bit stream, but I am not 100% sure (depends on what exactly CFHTTP is doing). Repeat process above. ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:344789 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: cfhttp response with non-english characters gets cut off
Dump HTTP headers and look at Content-Type header. There is a charset attribute that specifies the input stream encoding. Most likely it is missing or incorrect. If the charset is missing, CF assumes UTF-8. However, in UTF-8 any char with the code higher than 127, is treated as an escape code that initiates multibyte sequence (up to 6 bytes). Not all sequences are valid UTF-8 sequences. When CF tries to convert not valid UTF-8 stream, the truncation or abort happens. Any 8-bit code that uses high codes, will not be converted correctly, unless the proper charset setting is used. Looks like your case. Same will happen, if HTTP header says UTF-8, but the stream is, actually, some 8-bit national encoding. MSXML does not make any conversion. It assumes your default codepage (8-bit) and makes UTF-16 out of this. This is why you get all characters, but not necessarily correct ones. Resume. Provide correct charset parameter in CFHTTP. This might be tricky, since you may not always know how the original stream was encoded. ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:344636 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: ColdFusion and AJAX choices

Re: cfhttp response with non-english characters gets cut off
Andrei, one of my coworkers had much the same thought. The headers are reporting utf-8, and I've created a test document containing an omega character I've saved as plain text utf-8 encoded and it still truncates. Just created a text file that contains the entire Greek alphabet plus crazy Scandinavian characters using Character Map and save it locally in UTF-8 (notepad). Everything works, as it should be. I am 99% sure that your problem relates to charset encoding/decoding. I have CF8 here. If you post an actual URL that causes a truncation, it could help. ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:344703 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: ColdFusion and AJAX choices
Didn't really wanted to start a discussion. Just expressed my private opinion applied to this particular situation, not really trying to make any general claims. 1) It's 90k minified Only 90? Great! 2) Those 10 lines will inevitably be 1 line of jQuery No, my custom line will be 11th one. 3) Those 10 lines will work in your favorite browser; then you find that IE x has some quirk you didn't count on, etc XMLHTTPRequest is the only thing (thanks Computer God!) that works the same way everywhere. All browsers employ MS XMLHTTP interface. Only difference is in the initialization process, and this is why it requires 10 lines of code, not 1 or 2. 4) You and Claude S will best friends, I can tell Does it mean I am blacklisted now? jQuery core is only 229K uncompressed... This, of course, is much better than 300. Do those 10 lines of code enable you to write different handlers depending on the status code and success of the http call without any fuss? Do they translate common response formats into plain js objects for you? Yes, I could, but I don't need to, and I don't want to. I am calling MY Web-site, I know EXACTLY what to expect. I don't want library function to perform checks for situations, which will never happen. I want to have my own interface that fits my needs better. Unless I forced to do so, I will make entire HTML cooking on the server-side (this is why we use ColdFusion) and just dump results to the browser, to avoid annoying freezes of client's browser, while it processes JS objects, JSONs, XMLs, and created HTML on the fly. If you move server-side processing to the client side, than yes, you might need something like jQuery to help you with this. But, from my point of view, this is some different programming concept that significantly differs from the client-server paradigm that assumes that client must be as stupid and as simple, as possible. To be clear, even on Edge or 56K dial-up, non-cached Jquery, with all its built-in goodness, arrives in less than a second...so...I really can't imagine why rolling your own just-enough JS would be better. At least when it comes to speed/performance This is because you think that 1 sec is a short time and can be ignored. I have a different vision of this. I would fight for this 1 sec. As well as for the size of browser's working set. Clearly, use whatever you like...but...wrt your harvester analogy: when the harvester is free, doesn't impact speed/performance, and will handle the 10 square feet of grass and the 10 hectares of grass...I'm not seeing the drawback of using it for both No, this is a wrong example. The correct one is when you try to build a car that simultaneously can be used as a truck, limo, and participate in Formula-1. And yes, it must be electrical. Convertible? Please... Perhaps, you could build something like this, but in reality it is much better to have 3 or 4 DIFFERENT cars for different purposes. The only place where you can find a piece of free cheese is a mousetrap... jQuery (and other libraries) is well tested, well maintained, hugely popular and well thought out. All these things will have an impact on the speed of development and quality of code, especially for someone who wasn't coding before these things were commonplace. Andrei's assertion that using jQuery in this case would be 'nonsense' ignores these pertinent benefits and is itself nonsense. My definition of library is something that contains millions of books, but I can come there and borrow a SINGLE book I need, rather than carry back home all millions books. jQuery is a great exercise in JS programming. Never could imagine that so many things could be done in the browser! All those flying DIVs and popping images are amazing and REALLY require significant amount of efforts to create and maintain, especially considering the browsers war. But what it has to do with my simple task of dynamic update of the application screen? Therefore, my word nonsense should be applied to THIS situation ONLY and should NOT be used in any other context. Again, I did not try to offend anybody. The best language/tool/browser/etc. is the one you know. For example, we all reading this post because we all love ColdFusion and think it is the best. Want to learn an alternative point of view? Go to PHP or .NET forums. So, if you like jQuery, you comfortable with it, you totally trust and rely on it, could quickly produce desired results, or just because it is an internal standard of your company - USE IT. But don't tell me this how EVERYBODY should program, because this is the best, everybody use it, this is a common standard, it increases (??) the code quality, and so on, and so on. By the way, if people who created jQuery would think the same way, they would never created it in the first place, since it wasn't a common standard and not everybody used it. There are always attempts in the programming

Re: Problem with getting cfhttp to do a post
If POST from a browser works AND it is NOT an authetication issue, you should be able successuly POST using CFHTTP or CFX_HTTP5. Wondering, why do you have encoded=no set? Browsers, do URL-encoding of values before POST. So, you might be rejected, because some values you are posting are not decoded properly on their side. ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology-Michael-Dinowitz/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:337161 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
