Java in XSL

I would like to call java function in xsl to get logged in user. I see in the theme-examples.xsl you use the namespace version pointing to java class and then call the function. What class and function would be called to access the xxforms:get-remote-user() function? Or is there a different class and function I should be using? Thanks Brian Steuhl BTMSoftwareSolutions.com

I unpackaged the orbeon.jar file and located class file which when decompiled has getRemoteUser() method.  Why doesn't this work in my xsl file?

 xmlns:remoteUser="java:org.orbeon.oxf.externalcontext.ExternalContextToHttpServletRequestWrapper"

<xsl:variable name="remoteUser" select="remoteUser:getRemoteUser()" as="xs:string"/>

<xsl:value-of select="$remoteUser" />

I keep getting:

Error at line 33, column 86 of oxf:/config/theme-examples.xsl:
XPath syntax error at char 26 on line 33 in {remoteUser:getRemoteUser()}:
Cannot find a matching 0-argument function named {java:org.orbeon.oxf.externalcontext.ExternalContextToHttpServletRequestWrapper}getRemoteUser()

Thanks.

Brian,

xxforms:get-remote-user()  is a function we specifically expose to the
XForms engine. It is not available to the XSLT processor.

Here is some Saxon documentation on calling Java:

http://www.saxonica.com/documentation9.1/extensibility/functions.html

It's fairly easy to call static methods, but a pain to create objects
and call non-static methods on objects.

Also, ExternalContextToHttpServletRequestWrapper is not the right
place to get the remote user from XSLT.

StaticExternalContext.getStaticContext().getExternalContext().getRequest().getRemoteUser()
would be it.

Note that for security reasons, calling Java functions from XSLT only
works when the oxf:unsafe-xslt processor is used. By default, page
models/page views use oxf:xslt, which is the "safe" version with calls
to external functions disabled.

BTW you don't need to decompile, you can just get the source from github ;)
