cfindex:Unable to connect to the ColdFusion Search service

Wed, 20 Feb 2008 17:58:00 GMT

Problem I ran into recently where I knew the collection existed. Running Coldfusion 8 in multiserver configuration on a Windows machine that previously had Coldfusion 7 installed. Tried to use the cfindex tag to no avail.

Trial and error and some reading here on Adobe's site led me to this:

Uninstalled Coldfusion 7 Search Service still on the box
Checked cfadmin to see what ports should be used 9951, 9921 & 9961
Noted that k2index.exe and k2server.exe services were not running via cports (i.e. 9921 & 9961)
ran C:\JRun4\verity\verity-install.bat and noted the following errors:
1. WARNING: The RCAdmin call failed. Command = styleset 1 "Def_FileSystem" 1 1 filesys "default File System style files" y exit
2. WARNING: The RCAdmin call failed. Command = styleset 1 "ColdFusionK2" 1 1 filesys "ColdFusion K2 Style Files" y exit
3. WARNING: The RCAdmin call failed. Command = styleset 1 "ColdFusionVspider" 1 1 filesys "ColdFusion Vspider Style Files" y exit
4. WARNING: The RCAdmin call failed. Command = serverset 1 "ColdFusionK2_server1" 9921 "ColdFusion K2Server" y y y ColdFusionK2 "C:\JRun4\verity\k2\common" 200 2 n 300000 900000 y exit
5. WARNING: The RCAdmin call failed. Command = indexerset 1 "ColdFusionK2_indexserver1" 9961 "ColdFusion K2 Index Server" ColdFusionK2 4 1 y exit
ran C:\JRun4\verity\k2\_nti40\bin\rcadmin.exe
1. styledel Def_FileSystem
2. styledel ColdfusionK2
3. styledel ColdfusionVspider
ran C:\JRun4\verity\verity-install.bat (still will get serverset and indexerset failure messages)

Works again.

Think the problem is either because (a) had Coldfusion 7 search service installed or (b) the admin.xml files inside the verity directory (subdirectory) had bad values in them and running styledel and subsequently the .bat file resolved it.

XML StAX Processing with Coldfusion

Wed, 28 Mar 2007 15:04:00 GMT

Several problems with Coldfusion XML processing and solution set:

Slow: due to DOM processor (Xerces)
Inconsistent Round-Tripping (i.e. serialization / deserialization) :
1. (un-) escaping characters
2. non-printable characters
3. missing / multiple XML declaration(s)
4. character set problems
5. et al.
Kludgy Tree API yes you can use structure and array functions, just don't like it.

Note, don't see this as a flame on Adobe/Macromedia. The Coldfusion XML implementation uses best available technology at the time and APIs that fit in with the language paradigm. Just have better options now.

Slow Solution

Woodstox: Jim Collins wrote a CFDJ article about using a StAX XML processor with Coldfusion. Unfortunately, as near as I can tell, his open source project to integrate Coldfusion with Woodstox was never released. Testing demonstrates a StAX processor, such as Woodstox, provides very efficient (read: fast) XML processing, and a more intuitive API, than a SAX processor. But still not intuitive enough for me. So enter...

Round-Tripping & API Solutions

XOM provides a very easy to use API that roundtrips XML like a champ. Correct I/O is XOM's middle name. But it doesn't integrate natively with a StAX processor unless you use...

NUX is like a Swiss Army knife for XML. But the purpose of this entry just know it's the glue between XOM and Woodstox (note that NUX includes the XOM jar so you do not need to download it separately).

Code

Download the Woodstox and NUX jars and configure them in your Coldfusion classpath. The examples below build upon each other.

Setup

Creates a XOM Builder object backed by a StAX processor.

inputFactory = createObject("java", "com.ctc.wstx.stax.WstxInputFactory").init()
builder = createObject("java", "nux.xom.io.StaxUtil").createBuilder(local.joInputFactory, javacast("null", "")

XMLParse() Alternative

Returns a XOM Document object. Note: provide XMLString variable.

document = builder.create(XMLString)

XMLSearch() Alternative

Returns a XOM Nodes object (i.e. an iterator of Node objects). Note: provide XQueryString variable.

nodes = createObject("java", "nux.com.xquery.XQueryUtil").xquery(document, XQueryString)

loop from="0" to="#nodes.size() - 1#" index="idx"
element = nodes.get(javacast("int", idx))
attributeValue = element.getAttribute("attributeName").getValue()
attributeText = element.getValue
/loop

ToString() Alternative

Creates a string representation of the XML.

XMLString = document.toXML()
