fop 2 + xsl = Image not found

When moving from one server to another, pictures no longer appear when generating pdf using fop 2 + xsl

Trying to understand someone else's code when generating pdf using fop 2 + xsl I get in the logs

[FOUserAgent] Image not found. URI: test/myimg2/logo.png (No context info available)

relative paths are specified in xsl, the full path to the image will be /myserv/mydir/test/myimg2/logo.png

I read that in version fop 2 you can set the base url using FopFactoryBuilder

FopFactoryBuilder builder = new FopFactoryBuilder(new File("/myserv/mydir/").toURI(), resolver);

However, in my code the following construct

FopConfParser parser = new FopConfParser(new File(fopBaseDir, "userconfig.xml"));
FopFactoryBuilder builder = parser.getFopFactoryBuilder();

fopBaseDir - fop library directory
fonts are specified in userconfig.xml

builder is already created using userconfig.xml

Can you please tell me how can I specify the base URL for images? Can this be done in userconfig.xml?

i don't use servlets, JSF

I debugged the code and saw that after creating the fop object, BaseUri leads to the userconfig.xml file

fop -> foUserAgent -> ResourceResolver -> BaseUri = file:/myserv/etc/tomcat/fop/userconfig.xml

Is this normal? Or is the BaseUri not the base url that is used to search for images?

One of the working options when using the configuration file is to specify the base url settings there

<base>...</base>
<font-base>...</font-base>

I notice you've tagged the question with xslt; that suggests to me you might be willing to use an XSLT to pre-process your XSL-FO document and fix the image resource URLs, perhaps by using a template that matches fo:external-graphic/@src and prepends your image base URI, or just adds an xml:base attribute, e.g.

<xsl:stylesheet version="1.0" 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:fo="http://www.w3.org/1999/XSL/Format">

    <!-- supplement external-graphic's @src with a base URI -->
    <xsl:template match="fo:external-graphic/@src">
      <xsl:copy/>
      <xsl:attribute name="xml:base">file:/myserv/mydir/</xsl:attribute>
    </xsl:template>
    
   <!-- copy everything else unchanged -->
   <xsl:template match="node()|@*">
       <xsl:copy>
         <xsl:apply-templates select="node()|@*"/>
       </xsl:copy>
   </xsl:template>
   
</xsl:stylesheet>

You could even just set an xml:base attribute of /myserv/mydir/ on the XSL-FO document's root element, but beware that would also affect other relative hyperlinks in the document.
