Dear all,
I am using DSPACE 5.5 with Mirage theme. I want to add a javascript
function that calculates the SHA1. I have inserted in item-view.xsl the
following:
...
xmlns:tib="tib"
extension-element-prefixes="tib"
...
<xalan:component prefix="tib" functions="SHA1">
<xalan:script lang="javascript">
<![CDATA[
function SHA1(msg) { ... }
]]>
</xalan:script>
</xalan:component>
and the call:
<xsl:template name="TIB-Link-test">
<a>
<xsl:attribute
name="href">https://www.tib.eu/en/search/id/eg%3Asha_doi~<xsl:value-of
select="tib:SHA1($identifier_doi)"/>/</xsl:attribute>
<img height="64"
src="{concat($theme-path,'/images/tib.png')}" title="Buy-Link"/>
</a>
</xsl:template>
But it doesn't work. I am getting an java.lang.NullPointerException:
*Unknown error in XPath.*
context:/file:///var/lib/tomcat8/webapps/ROOT/themes/Mirage_EG/lib/xsl/core/page-structure.xsl

I have nothing changed in page-structure.xsl. What am I doing wrong?
Any help is appreciated.
