Character problems with xsql:include-xsql reparse="yes"

Question

I have a problem retrieving XML-fragments from CLOB columns.
Danish ISO-8859-1 characters (aelig, oslash, aring) are returned as "?" from Apache/Jserv when using xsql:include-xsql reparse="yes".
My platform is Solaris9/Oracle-9.2.0.2/XDK-9.2.0.4.
Database characterset is we8iso8859p1.
I'm using the Apache/Jserv that comes with Oracle 9.2.0.1.
Steps to reproduce problem:
-- Table data:
create table tab1 (id number,clob_col clob);
insert into tab1 values(1, '<x>fxe</x>');
/*inserted characters are aelig(230), oslash(248), aring(229)*/
commit;
-- test.xsql:
<?xml version="1.0" encoding="ISO-8859-1"?>
<testdata xmlns:xsql="urn:oracle-xsql" connection="pnrtest">
<xsql:include-xsql reparse="yes" href="inc.xsql" />
</testdata>
-- inc.xsql:
<?xml version="1.0" encoding="ISO-8859-1"?>
<?xml-stylesheet type="text/xsl" href="unquote_clob_col.xsl"?>
<xsql:query
xmlns:xsql="urn:oracle-xsql"
connection="pnrtest"
tag-case="lower"
>
select clob_col
from tab1
</xsql:query>
-- unquote_clob_col.xsl:
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="xml" indent="yes" omit-xml-declaration="no" encoding="ISO-8859-1"/
<xsl:include href="identity.xsl"/>
<xsl:template match="clob_col">
<clob_col>
<xsl:value-of select="." disable-output-escaping="yes"/>
</clob_col>
</xsl:template>
</xsl:stylesheet>
-- identity.xsl:
<!-- The Identity Transformation -->
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<!-- Whenever you match any node or any attribute -->
<xsl:template match="node()|@*">
<!-- Copy the current node -->
<xsl:copy>
<!-- Including any attributes it has and any child nodes -->
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
-- Notes:
Running test.xsql works fine with XSQL command-line, but FAILS through Apache/Jserv (danish characters are returned as "?").
inc.xsql works fine through XSQL command-line and Apache/Jserv, problem only happens with xsql:include-xsql reparse="yes" (e.g. test.xsql).
xsql:include-xml works fine, but I cannot use this, bca. in my real business case I'm selecting more than one row from the database.
I've checked and double-checked my jserv.properties several times, and believes it to be correct.
The xsql:include-xsql reparse="yes" technique works fine in our Solaris9/Oracle-8.1.7/iAS-1.0.2.2 environment.
Any suggestions ?

Answer 1

If I put the following line in jserv.properties:
wrapper.env=LANG=en_US.ISO8859-1
the problem with xsql:include-xsql reparse="yes" seems to go away.
Really strange, since Oracle products in my experience normally only uses NLS_LANG, not LANG.
Also, we're accessing several databases with different charactersets from the same ApacheJserv installation, so I don't understand why LANG (or NLS_LANG) should be set to a particular value.
Can anybody explain ?
