Hi,
I'm trying to create a dynamically constructed pipe using endpoints loaded
from a database at runtime. 'ToD' is being used with a header to set the
endpoint.
Camel version used is '3.0.0-M4', although I'm having a similar issue with
2.13.1
The XMLDSL for the main loop is as follows :
<route id="dynamicPipe">
<!-- Iterate through filters -->
<from uri="direct:dynamicPipe"/>
<!-- Populate header 'myFilter' with the endpoint uri -->
<bean ref="pipeManager" method="popFilter"/>
<when>
<simple>${header.myFilter}</simple>
<toD uri="${header.myFilter}"/>
<to uri="direct:dynamicPipe"/>
</when>
</route>
This works well for simple bean calls or logging, for example :
log:com.test.log?level=DEBUG
bean:jsonTools?method=convertXMLtoJSON
However when attempting to use the XSLTComponent with the bean scheme for
XSLT lookup, I'm getting an error.
The endpoint string is :
xslt:bean:entityCache.getXslt(${header.callerId},'myXSLT')?contentCache=false
or
<toD
uri="xslt:bean:entityCache.getXslt(${header.callerId},'myXSLT')?contentCache=false"/>
The stack trace is :

Any ideas? I've attempted to write a custom URIResolver instead but Im
having trouble passing all the information I'd like to (callerId,
artefactId) so it can lookup the required entity from a database.
Many Thanks,
James.
