Hi ESB Team, I think it's not right to resolve these kind of issues as "Not a bug"!
More details are available in the JIRA comments. Please provide an acceptable solution to the issue. Thanks! Best Regards, ---------- Forwarded message ---------- From: Boguslaw Szczepanowski (JIRA) <[email protected]> Date: Tue, Mar 25, 2014 at 5:21 PM Subject: [Carbon-jira] [jira] (ESBJAVA-3064) ESB proxy service does not start if target is unavailable To: [email protected] Boguslaw Szczepanowski <https://wso2.org/jira/secure/ViewProfile.jspa?name=boguslaw.szczepanowski%40ingbank.pl> created [image: Bug] ESBJAVA-3064 <https://wso2.org/jira/browse/ESBJAVA-3064> *ESB proxy service does not start if target is unavailable* <https://wso2.org/jira/browse/ESBJAVA-3064> *Issue Type:* [image: Bug] Bug *Affects Versions:* 4.8.1 *Assignee:* Kasun Indrasiri <https://wso2.org/jira/secure/ViewProfile.jspa?name=kasun%40wso2.com> *Created:* 25/Mar/14 5:20 PM *Description:* I have a simple Proxy Service deployed on WSO2 ESB. The service is defined as follow: <?xml version="1.0" encoding="UTF-8"?> <proxy xmlns="http://ws.apache.org/ns/synapse"; name="HelloWorld" transports="https http" startOnLoad="false" trace="enable" statistics="enable"> <description/> <target> <endpoint> <wsdl service="HelloWorld" port="HelloWorldImplPort" uri="http://myhostname:9001/HelloWorldInternal?wsdl";> <suspendOnFailure> <errorCodes>101508,101505,101503,101504</errorCodes> <initialDuration>1000</initialDuration> <progressionFactor>1.1</progressionFactor> <maximumDuration>30000</maximumDuration> </suspendOnFailure> </wsdl> </endpoint> <outSequence> <log level="full"/> <send/> </outSequence> </target> <publishWSDL uri="http://myhostname:9001/HelloWorldInternal?wsdl"/> </proxy> When I start WSO2 ESB when the target service is down, I get the following error in ESB logs: [2014-02-20 14:25:05,168] INFO - ProxyService Building Axis service for Proxy service : HelloWorld [2014-02-20 14:25:06,176] ERROR -

The only way to make my proxy service visible again, is to touch it's configuration file, so it gets redeployed. *Environment:* Microsoft Windows 7, Oracle JDK 1.7.0_03 *Project:* WSO2 ESB <https://wso2.org/jira/browse/ESBJAVA> *Priority:* [image: Normal] Normal *Reporter:* Boguslaw Szczepanowski <https://wso2.org/jira/secure/ViewProfile.jspa?name=boguslaw.szczepanowski%40ingbank.pl> This message is automatically generated by JIRA.
