Synapse2: Question about XPath Expressions in SwitchMediator
Hi,
I am using Apache Synapse 2.0-SNAPSHOT and I have a problem with XPATH
expressions.
I have defined the following configuration:
..
<configuration:switch
source="{http://mytravelagency.com}searchFlights/{http://mytravelagency.com}destination">
..
which should be a a valid XPATH expression.
Synapse throws the following exception:
ERROR SynapseServer - Error starting Apache Synapse, trying a clean shutdown...
org.apache.synapse.SynapseException: Invalid XPath for attribute
'source' : {http://mytravelagency.com}searchFlights/{http://mytravelagency.com}destination
at org.apache.synapse.config.xml.SwitchMediatorFactory.createSpecificMediator(SwitchMediatorFactory.java:71)
at org.apache.synapse.config.xml.AbstractMediatorFactory.createMediator(AbstractMediatorFactory.java:88)
......
I've also looked at the code and saw that the SwitchMediatorFactory
directly calls new SynapseXPath(xpathAttrib.getAttributeValue()),
whereas in your test cases you are rather using the
SynapseXPath.parseXPathString(XPATHString) method which does some
preprocessing especially with namespaces. Wouldn't it be better to use
that method in the Switch MediatorFactory instead ?
Thanks,
Benjamin

Hi,
have you already fixed the problem with xpath in switch? I've
installed the 2.0 release of Synapse, but the problem still remains.
Thanks,
Benjamin

Hi,
to fix it you can replace the following line in
SynapseXPathFactory.getSynapseXPath(elem, ATT_SOURCE):
LINE 47: xpath = new SynapseXPath(xpathAttrib.getAttributeValue());
by xpath = SynapseXPath.parseXPathString(xpathAttrib.getAttributeValue());
Thanks,
Benjamin

I think you are correct, let me have a look at using the parseXPathString
instead of the current one.

Synapse2: Question about XPath Expressions in SwitchMediator
Posted by Benjamin Schmeling <be...@googlemail.com>.
Hi,
I am using Apache Synapse 2.0-SNAPSHOT and I have a problem with XPATH
expressions.
I have defined the following configuration:
..
<configuration:switch
source="{http://mytravelagency.com}searchFlights/{http://mytravelagency.com}destination">
..
which should be a a valid XPATH expression.
Synapse throws the following exception:
ERROR SynapseServer - Error starting Apache Synapse, trying a clean shutdown...
org.apache.synapse.SynapseException: Invalid XPath for attribute
'source' : {http://mytravelagency.com}searchFlights/{http://mytravelagency.com}destination
at org.apache.synapse.config.xml.SwitchMediatorFactory.createSpecificMediator(SwitchMediatorFactory.java:71)
at org.apache.synapse.config.xml.AbstractMediatorFactory.createMediator(AbstractMediatorFactory.java:88)
......
I've also looked at the code and saw that the SwitchMediatorFactory
directly calls new SynapseXPath(xpathAttrib.getAttributeValue()),
whereas in your test cases you are rather using the
SynapseXPath.parseXPathString(XPATHString) method which does some
preprocessing especially with namespaces. Wouldn't it be better to use
that method in the Switch MediatorFactory instead ?
Thanks,
Benjamin
