I'm using OSB 12c and JDeveloper 12.2.1.2.0.
How I can use and create XSLT functions with conjunction of xs constructor functions like xs:integer, xs:string or xs:date ? The following XSLT transformation results in my JDeveloper an error:
The first argument to the non-static Java function 'xecho' is not a valid object reference.
That prevents deployment from JDeveloper.
e002-transform.xsl:

\<!-- OSB 12c works when the following line is commented.
When the line is enabled the following error is reported by JDeveloper:
The first argument to the non-static Java function 'xecho' is not a valid object reference. -->
\<xsl:value-of select="xs:integer(.)"/>
\</integerOriginal>
\<integerDoubled>
\<xsl:value-of select="jh:xdouble(.)"/>
\</integerDoubled>
\</xsl:template>
\<xsl:template match="string">
\<stringEcho>
\<xsl:value-of select="jh:xecho(.)"/>
\</stringEcho>
\</xsl:template>
</xsl:stylesheet>
When the above transformation is run in XMLSpy 2018 the following input file:
<input>
\<integer>1\</integer>
\<integer>13\</integer>
\<integer>42\</integer>
\<string>20-Mar-2018\</string>
\<string>Lorem ipsum\</string>
</input>
Is (correctly) transformed to the following output:
<?xml version="1.0" encoding="UTF-8"?>
<output>
\<integerOriginal>1\</integerOriginal>
\<integerDoubled>2\</integerDoubled>
\<integerOriginal>13\</integerOriginal>
\<integerDoubled>26\</integerDoubled>
\<integerOriginal>42\</integerOriginal>
\<integerDoubled>84\</integerDoubled>
\<stringEcho>20-Mar-2018\</stringEcho>
\<stringEcho>Lorem ipsum\</stringEcho>
</output>
In OSB the transformation is executed in a trivial pipeline assign action:
