Hi All, I am using an XPATH expression as follows,
<sequence xmlns="http://ws.apache.org/ns/synapse"; name="sequence1"> <log level="custom"> <property xmlns:ns="http://org.apache.synapse/xsd"; xmlns:fn="http://www.w3.org/2005/xpath-functions"; name="insq" expression="fn:string-join('name','age', '-')"/> </log> <drop/> </sequence> When I invoke the proxy I am getting an error as follows SynapseXPath Evaluation of the XPath expression fn:string-join('name','age', '-') resulted in an error org.jaxen.UnresolvableException: No Such Function {http://www.w3.org/2005/xpath-functions}:string-join at org.jaxen.SimpleFunctionContext.getFunction(SimpleFunctionContext.java:127) at org.apache.synapse.util.xpath.SynapseXPathFunctionContext.getFunction(SynapseXPathFunctionContext.java:93) at org.jaxen.ContextSupport.getFunction(ContextSupport.java:242) at org.jaxen.Context.getFunction(Context.java:216) at org.jaxen.expr.DefaultFunctionCallExpr.evaluate(DefaultFunctionCallExpr.java:172) at org.jaxen.expr.DefaultXPathExpr.asList(DefaultXPathExpr.java:102) at org.jaxen.BaseXPath.selectNodesForContext(BaseXPath.java:674) at org.jaxen.BaseXPath.selectNodes(BaseXPath.java:213) at org.jaxen.BaseXPath.evaluate(BaseXPath.java:172) at org.apache.synapse.util.xpath.SynapseXPath.stringValueOf(SynapseXPath.java:297) at org.apache.synapse.mediators.MediatorProperty.getEvaluatedExpression(MediatorProperty.java:138) at org.apache.synapse.mediators.builtin.LogMediator.setCustomProperties(LogMediator.java:192) at org.apache.synapse.mediators.builtin.LogMediator.getCustomLogMessage(LogMediator.java:131) at org.apache.synapse.mediators.builtin.LogMediator.getLogMessage(LogMediator.java:117) at org.apache.synapse.mediators.builtin.LogMediator.mediate(LogMediator.java:91) at org.apache.synapse.mediators.AbstractListMediator.mediate(AbstractListMediator.java:77) at org.apache.synapse.mediators.AbstractListMediator.mediate(AbstractListMediator.java:47) at org.apache.synapse.mediators.base.SequenceMediator.mediate(SequenceMediator.java:131) at org.apache.synapse.mediators.AbstractListMediator.mediate(AbstractListMediator.java:77) at org.apache.synapse.mediators.AbstractListMediator.mediate(AbstractListMediator.java:47) at org.apache.synapse.mediators.base.SequenceMediator.mediate(SequenceMediator.java:131) at org.apache.synapse.core.axis2.ProxyServiceMessageReceiver.receive(ProxyServiceMessageReceiver.java:166) at org.apache.axis2.engine.AxisEngine.receive(AxisEngine.java:180) at org.apache.synapse.transport.passthru.ServerWorker.processEntityEnclosingRequest(ServerWorker.java:411) at org.apache.synapse.transport.passthru.ServerWorker.run(ServerWorker.java:183) at org.apache.axis2.transport.base.threads.NativeWorkerPool$1.run(NativeWorkerPool.java:172) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:722) According to [1] it states the string-join function should be as follows, fn:string-join(('name','age'), '-') - with two brackets but when I try to do so, ESB doesn't support this.
