Hello,
we are using Cocoon 2.0.1, Tomcat 4.0.2, JDK 1.3.1 and try to develop
something with XSP using external Java-Classes to access Databases and
performs some Calculation.
The two files (I know, there are a few things that can be done in a better
way, like xsp:include in example.xsl ...) show our problems and are an
extract of a larger file. We are using the example.xsl as a logicsheet and
setup everything in cocoon.xconf, inserted the required fields in
sitemap.xmap to match example.xsp with the serverpages-gererator (Can
provide the files if neecessary). Basically, all this works, especially the
output of our database-request is stored in msg and printed on the screen:
OUTPUT: file:///home/vorms/lomobjects/lo/vorms/tp3/author/stefanvoss_1_1.0.xml
We have to problems:
1: There seems to be some kind of caching in a way we do not want. We
assume that the xsp is compiled to a generator whenever we change something
in one of the files and reload the page in a browser (we tried 5 browser,
all have the same problem). E.g., these files produce the output above. If
we change something in the xsl-file (like the "file://" in "foo://", the
pages in the browser do not change. Furthermore, even a restart of cocoon
(and tomcat) sometimes are not working either. Strange to say, it works
sometimes but we could not discover any pattern. The question is: How do we
prevent a caching and force a recompilation of the xsp-pages whenever we
have a reload in the browser.
2: We want to set a xsl:variable to the value of the variable of "msg"
being part of the xsl:logic. Using this structure, it seems that the
xsp:expr is not evaluated and therefore not working. Is there any way to do
this.
<xsl:variable name="toInsert">
<xsp:expr> msg </xsp:expr>
</xsl:variable>
The reason for this solution is that we want to include another file with
<xsl:apply-templates select="document($toInsert)" />
and within document it is not allowed to use <xsp:expr>.
Thanks for your help
Torsten
