Newbie: Best practices for DocBook XSL on Cocoon

[Joe Williams]

I have a question about using DocBook XSL with Cocoon, for anyone who has been successful in doing so. In hopes of getting some help and maybe helping others, I offer the following background.   After reading numerous posts to the archives for this list, and other resources, I am aware that not everyone is in favor of using the DocBook XSL stylesheets with Cocoon. However, I have also found that some people have done so successfully, and would like to do so myself.   I have been successful in serving DocBook XML content with a homegrown XSL stylesheet and CSS, but when I attempted to use the DocBook XSL to produce html, I get a blank page. (The transform runs fine from the command line.)   Looking at cocoon/WEB-INF/logs/error.log I see a fatal exception in "docbook/html/common/common.xsl; Line 1576; Column 35", "javax.xml.transform.TransformerException: 13 >= 1" and farther down in the log, I see "java.lang.ArrayIndexOutOfBoundsException: 13 >= 1"   Going to "docbook/html/common/common.xsl; Line 1576; Column 35", I see the following:   <xsl:when test="$value !="''">   OK, so xalan doesn't like this line, I guess?   Here's my setup:   Cocoon 2.0.3   Using these classes in /usr/tomcat/webapps/cocoon/WEB-INF/lib:   xalan-2.3.1.jar   xalan2.jar (docbook extensions from Norm)   xercesImpl-2.0.0.jar   xml-apis.jar   Using jre 1.3.1_06   DocBook XML DTD 4.2   DocBook XSL 1.5   I would like to keep using xalan, but if I have to add saxon, please point me to a good procedure for doing so. Ditto for any other suggestions.   When I get the setup working, I will post the info to the list.   Thanks.   Joe
