Custom tags in CF9

Nosredna, here's a possible explanation why some work for you and some do not. When "registering" the java CFXs, have you noticed that you don't specify their location? That's because they're expected to be found in places that CF can find them, as defined by the classpath configured for CF, which includes a couple of default locations: in the WEB-INF/classes directory if .class files, or in the WEB-INF/lib for .jar files.

Also, you can tell CF to find them in other locations, by modifying the classpath, either in the CF Admin (Java and JVM page) or in the jvm.config.

I wonder if the ones that are working for you are found in the default locations, and the ones that are not are in locations that either weren't brought forward and specified in the classpath for your upgraded server, or perhaps the paths are there but not correct (if this is a new server).

Much of this is discussed in the CF docs, such as a series of pages starting here:

for CF8: http://livedocs.adobe.com/coldfusion/8/htmldocs/help.html?content=CFXTags_4.html.

for CF9 (same text): http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec0a4b8-7ffb.html

You say that "Obviously, CF9 handles custom tags differently but I can't find any documentation on this". I'm really not aware of any changes in this regard, since CF 6.

As for not finding any docs, if you mean about a change in CF9, well, there isn't any as far as I know, not since CF4.51 when Java CFXs were introduced (though the default locations for classes and lib did change as of CF 6.)

If you may have meant that you could find no docs on registering CFXs at all, well, a common problem is that people tend to focus solely on the CFML Reference. The doc I point to above is in the Developer's Guide. There is also an Admin and Config Guide:

for CF8: http://livedocs.adobe.com/coldfusion/8/htmldocs/Part_2_Config_Admin_1.html

for CF9: http://help.adobe.com/en_US/ColdFusion/9.0/Admin/index.html

Though that really doesn't offer much on CFXs. Instead, it points readers to the online help, which again people often miss. This is referring to the help icon within the CF Admin. And that page (called from the CFX page) does indeed offer information on registering CFXs and these paths in which to place them, or the need to modify the classpath.

Hope that helps.

If you are using CF enterprise license , in CF administrator, there is a option of building CAR file. You can use this to migrate your CFX tag from CF 7 to 9.

If you using CF standard, then make it in developer edition and then this option will come in CF admin
