Axis2 HTTPS client error: Parser already accessed!

Problem:
 
  I am trying to use HTTPS for the client side of an Axis2 web-service.

  Running the service over HTTP works fine. I am currently configuring
the client
  use http by setting the targetEndPoint as 
  "https://localhost:8443/axis2/services/billing" in my client Stub
(generated using
  WSDL2Java).
 
  But when I try to use HTTPS,  an exception is thrown by the client.

  The error seems to be very similar to the bug (AXIS2-1380) where the
error was caused by
  calling a service through a proxy.  However I am not using a proxy.
 
  I am trying to determine if this is a problem with my code, with
Tomcat or with Axis2.
 
  Has anyone else come across this problem?


Platform:
 
    Java JDK 1.5.0_09
    Tomcat 5.5.17 (non-native mode) (cannot use native DDL with HTTPS
due to Tomcat bug)
    Axis2.0 version 1.0
    Windows XP SP2
 
Keystore and Tomcat configuration:
 
  I generated the keystore using the instructions on the Tomcat website 
  (http://tomcat.apache.org/tomcat-5.0-doc/ssl-howto.html)
 
  The command issued was:
 
    %JAVA_HOME%\bin\keytool -genkey -alias tomcat -keyalg RSA
 
    The generated keystore file was then copied to the Tomcat conf
directory.

The Tomcat server.xml was configured as follows:
 
    <Connector
        allowTrace="true"
        port="8443"
        scheme="https"
        keystoreFile="conf/.keystore"
        sslProtocol="TLS"
        maxSpareThreads="75"
        maxThreads="150"
        uRIEncoding="null"
        minSpareThreads="25"
        secure="true"
        clientAuth="false">
    </Connector>

I do not send any login information. I just need to use HTTPS for
secure transport.

Do you send any login information. Do you use the
HttpTransportProperties.Authenticator to set any user name password?
If you do, HttpTransportProperties.Authenticator has a setAllowedRetry
flag, please try switching that on.

Martin,

please see my email on this thread :) No need to hack the code (hopefully!)

Re: Axis2 HTTPS client error: Parser already accessed!

Posted by Martin Gainty <mg...@hotmail.com>.
Mike-

Most probably an unhandled exception when OMElement serializes..a solution is available at
http://mail-archives.apache.org/mod_mbox/ws-axis-dev/200606.mbox/%3Cb8d11a3b0606012222y49cc495cv1a558b8f5cb550e@mail.google.com%3E

Anyone else?

Subject: Axis2 HTTPS client error: Parser already accessed!



Problem:
 
  I am trying to use HTTPS for the client side of an Axis2 web-service.

  Running the service over HTTP works fine. I am currently configuring
the client
  use http by setting the targetEndPoint as 
  "https://localhost:8443/axis2/services/billing" in my client Stub
(generated using
  WSDL2Java).
 
  But when I try to use HTTPS,  an exception is thrown by the client.

  The error seems to be very similar to the bug (AXIS2-1380) where the
error was caused by
  calling a service through a proxy.  However I am not using a proxy.
 
  I am trying to determine if this is a problem with my code, with
Tomcat or with Axis2.
 
  Has anyone else come across this problem?


Platform:
 
    Java JDK 1.5.0_09
    Tomcat 5.5.17 (non-native mode) (cannot use native DDL with HTTPS
due to Tomcat bug)
    Axis2.0 version 1.0
    Windows XP SP2
 
Keystore and Tomcat configuration:
 
  I generated the keystore using the instructions on the Tomcat website 
  (http://tomcat.apache.org/tomcat-5.0-doc/ssl-howto.html)
 
  The command issued was:
 
    %JAVA_HOME%\bin\keytool -genkey -alias tomcat -keyalg RSA
 
    The generated keystore file was then copied to the Tomcat conf
directory.

The Tomcat server.xml was configured as follows:
 
    <Connector
        allowTrace="true"
        port="8443"
        scheme="https"
        keystoreFile="conf/.keystore"
        sslProtocol="TLS"
        maxSpareThreads="75"
        maxThreads="150"
        uRIEncoding="null"
        minSpareThreads="25"
        secure="true"
        clientAuth="false">
    </Connector>
 

Exception thrown by Axis2 client:
