Hello group,
I created a minimal webapp and found the following remark from Geoff Howard in
[1 href="http://wiki.cocoondev.org/Wiki.jsp?page=CreateMinimalWebapp";]
CreateMinimalWebapp:
2. edit lib/jars.xml to comment out/remove all the optional jars except the ones noted
above
1. could be done with an xsl transform
[/1]
I wrote 2 XSLT- files that are working fine to do the job, but I would like to have
more "intelligence" (please see below):
The first xslt (jars2exclude.xsl [2]) checks the <lib> element form the jars.xml
whether it starts with 'optional/' (the dir to exclude files from). If so they will
be labeled "2exclude" (there are exceptions - you will see later).
<xsl:when test="starts-with(text(), 'optional/')"> [compare 2]
The jars.xml looks like this:
...
<file>
<title/>
<description/>
<used-by/>
<lib>core/jvm1.2/excalibur-datasource-vm12-20021121.jar</lib>
<homepage/>
</file>
...
The example file would not meet the criteria. The following would:
<file>
...
<lib>optional/servlet_2_2.jar</lib>
...
<file>
But this certain file has to be left untouched [1] - this is one of n exceptions (2
are mentioned in [1], but I need more<-n exception). This is be done with
<xsl:choose><xsl:when>[2]. Here is an example of an exception:
<xsl:when test="substring-after(text(), 'optional/')='servlet_2_2.jar'">
<xsl:value-of select="."/>
</xsl:when>
The result of the transformation [2] will look like this:
<file>
<title>XML Catalog Entity Resolver</title>
...
<lib>2exclude</lib>
...
</file>
<file>
<title>Servlet API</title>
...
<lib>optional/servlet_2_2.jar</lib>
...
</file>
Transforming this result with exclude2jars.xsl [3] will result in the new jar.xml
(without the exclusions, but with the exceptions).
Ok, that is nice but I would prefer not to hard code the exceptions, e.g.:
substring-after(text(), 'optional/')='servlet_2_2.jar'
|------------| |--------------------|
|---| hard coded exception (e.g. |optional/|
I prefer to use something like jars2exclude.xml [4] where I declare the |---| hard
coded exceptions.
...
<dir2exclude>optional/</dir2exclude>
<except>servlet_2_2.jar</except>
...
..but how can I do that?
Have a look at sitemap.snippet [5] to install it on your local cocoon version.
Any help and any ideas welcome.
King regards
Thorsten
