Known Issues

1. It is not possible to use the HTTPS transport with a JDK version below 1.5

If a JDK version below 1.5 is being used, the existing <transportReceiver> and <transportSender>

elements of the conf/axis2.xml must be replaced as follows. This will allow the admin console

to run over the HTTPS transport, although services are accessible only over HTTP.

Replace

<transportReceiver name="https"
class="org.apache.axis2.transport.nhttp.HttpCoreNIOSSLListener">



...



</transportReceiver>






With:



<transportReceiver name="https"
class="org.wso2.esb.transport.jetty.HttpsTransportListener">



<parameter name="port" locked="false">9443</parameter>



<parameter name="max.idle.time.ms"
locked="false">30000</parameter>



<parameter name="keystore" locked="false">



<KeyStore>



<Location>lib/identity.jks</Location>



<Type>JKS</Type>



<Password>password</Password>



<KeyPassword>password</KeyPassword>



</KeyStore>



</parameter>



</transportReceiver>

And, Replace

<transportSender name="https" class="org.apache.axis2.transport.nhttp.HttpCoreNIOSSLSender">

...

</transportSender>

With

<transportSender name="https" class="org.apache.axis2.transport.http.CommonsHTTPTransportSender">

<parameter name="PROTOCOL" locked="false">HTTP/1.1</parameter>

<parameter name="Transfer-Encoding" locked="false">chunked</parameter>

</transportSender>

2. Dependencies are currently allowed to be removed while they have live references to them

The ESB UI currently does not perform a check on references before the elements are removed. Thus there is a possibility of defining references to non-existent endpoints, sequences etc. as

well as removing them while live references still exist.

3. Inability to run axis2server.bat and wso2-esb.bat from a path which exceeds 255 characters in a MS Windows operating system
