Proxy Authentication Required in a Web Service call

Hi, we have a problem with our WebService.

In fact we created a webservice using the eclipse plugins.

We now have a webservice project with a portalapp.xml file which is the following :

<?xml version="1.0" encoding="iso-8859-1"?>

<application alias="WebServicePlanchettes">

<application-config>

<property name="SharingReference" value="com.sap.portal.runtime.application.soap">

</property>

</application-config>

<components>

</components>

<services>

<service name="WebServicePlanchettes" alias="WebServicePlanchettes">

<service-config>

<property name="className" value="com.stibmivb.portal.service.WebServicePlanchettes.WebServicePlanchettes">

</property>

<property name="startup" value="true">

</property>

<property name="WebEnable" value="true">

</property>

<property name="WebProxy" value="false">

</property>

<property name="SecurityZone" value="com.sap.portal.pdk/low_safety">

</property>

</service-config>

</service>

</services>

</application>

The problem is that we always receive an error telling :

javax.xml.soap.SOAPException: Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy service is denied. ) (proxy host: 10.1.2.35, proxy port: 80, non proxy host: localhost|.irisnet.be|portdev.|sto1513s)

But the URL of our WebService is http://sto1513s/planchettesXML/planchettesXML.asmx and this server is listed in the non-proxy hosts !

We've added it using the J2EE config tool and also via the portal itself by editing the proxy object of the com.sap.portal.ivs.httpservice service.

After these changes we've restarted the Server.

Has anybody an idea why our webservice seems to still try to go through the proxy ?

Thank you in advance,

Xavier.
