After migrating from glassfish 4.1.2 to glassfish 5 in our project, grizzly is throwing the following exception:

I tried the following commands to change maximum headers on running server-config:
asadmin set configs.config.server-config.network-config.protocols.protocol.http-listener-1.http.max-request-headers=1000
asadmin set configs.config.server-config.network-config.protocols.protocol.http-listener-2.http.max-request-headers=1000
asadmin set configs.config.server-config.network-config.protocols.protocol.http-listener-1.http.max-response-headers=1000
asadmin set configs.config.server-config.network-config.protocols.protocol.http-listener-2.http.max-response-headers=1000
But with no luck. Still grizzly throwing exception Illegal attempt to exceed the configured maximum number of headers: 100
How to fix the problem?
start glassfish
bring up the admin console
navigate to Configuration->HTTP Service->HTTP Listeners->http-listener-1->HTTP
set Send Buffer Size and Header Buffer Length
restart glassfish

I developed an API which will trigger email alerts based on some business requirements. To raise email alerts, I used cloudHub create-notification connector. The connector configuration is below:
<cloudhub:config name="CloudHub_Config" doc:name="CloudHub Config">
<cloudhub:connection
username="${ch.username}"
password="${ch.password}"
environment="${environment.id}"/>
</cloudhub:config>
Username and password are configured in Runtime manager > Application > properties, and the user has required permissions which I verified in Access Management. A Custom Application Notification alert is configured on correct environment in Runtime manager.
I am using below code to generate alerts from mule flows.
<cloudhub:create-notification doc:name="Success" config-ref="CloudHub_Config" domain="${domain}" priority="INFO">
<cloudhub:message><![CDATA[#["
Success scenario
Hello user"]]]>
</cloudhub:message>
<cloudhub:custom-properties><![CDATA[#[output application/java
---
{
"category" : "Info",
"status" : "Success"
}]]]>
</cloudhub:custom-properties>
</cloudhub:create-notification>
I tested this flow on 4.4.0 (latest) runtime on Studio pointing to AnyPoint platform TEST environment, and it was success. I deployed the same code to cloudHub worker (within VPC) and it failed test-connection during application start-up. The deployment went through and started successfully, but it fails when executing the component from flows. The error details is:

Scenarios I tried:
Running the same code on 4.3.0 runtime on same cloudHub
worker within VPC - IT FAILED.
Running the same code on 4.4.0 (latest) runtime on another
AnyPoint platform's cloudHub worker which is not on VPC - IT WORKED FINE.
Seems like connectivity of cloudHub-notification component running on worker within VPC is causing SSL handshake error. Strange that this component doesn't provide any settings to configure SSL.
Has anyone faced this issue before, if yes - please help me here?
Hi All can validate my implementation of SSL over glassfish PLEASE ?
I have a domain cloud3.dyalogodev.com into my glassfish server.
The SSL its ok charge but the render of my application is very slow, can you test.
https://cloud3.dyalogodev.com:8182/dyalogocbx/
BUt without https is fast:
http://cloud3.dyalogodev.com:8081/dyalogocbx/

PLEASE HELP ME, THanks advance.
This is NOT a solution to your interesting problem, but I need more space than the comments allow to provide some feedback.
On a Windows 10 machine I tried the URL https://cloud3.dyalogodev.com:8182/dyalogocbx/ in several browsers: Chrome, Edge, Firefox, Opera and Vivaldi.
The response was fast in all browsers except Firefox where the response took about a minute to complete.
Using Web Developer > Performance I captured the Waterfall output. See the screen shot below.
It seems that almost all the time is being spent in various phases of Garbage Collection (CC Graph Reduction, Non-incremental GC, Minor GC and Cycle Collection), or transitions between those phases. The screen shot shows that about 16 seconds was spent doing nothing but CC Graph Reduction which Mozilla describes as "Preparation/pre-optimization for Cycle Collection". Something is clearly wrong for that to be taking so long.
Note that at the bottom of the screen shot there are also a couple of warnings
Loading failed for the <script> with source “https://cloud3.dyalogodev.com:8182/dyalogocbx/javax.faces.resource/jquery/jquery-plugins.js.jsf?ln=primefaces&v=6.0”.
TypeError: this.jq.draggable is not a function[Learn More]
The information above is only descriptive, not diagnostic. I have no idea what is causing the problem. Perhaps you could simplify the code in your JSF page, and then if the performance problem goes away progressively reintroduce the complexity.
I think this problem may be more suitable for a Mozilla forum or SuperUser than Stack Overflow.
This is the error I get when trying to connect to an SFTP server running SSH-2.0-OpenSSH_7.1 using Coldfusion 10:

port, key, connection, proxyServer, and secure (as applicable).

This is the code. Obviously the asterisks have values, just commenting them out for obvious reasons.

that issue is reported as a bug: https://tracker.adobe.com/#/view/CF-4014234
the solution is to update CF to the latest version: Cf Admin Panel > Server Update > Updates
specifically this bug has been resolved in the ColdFusion 11 Update 14 version
I am new to OpenAM and trying to learn by setting up an authentication solution involving a SAML2 service provider, SAML2 IdP Server, SAML2 IdP proxy.
I am able to set up a service provider, an identity provider and currently at the stage of setting up the IdP proxy "Step3: Configuring the Identity Provider Proxy (machineb)" in the guide SAMLv2 IDP Proxy Part 1. Setting up a simple Proxy scenario.
I am able to complete till "Step 3: b" and when I try "Step 3: c", I am getting the Null Pointer Exception.
My set-up is slightly different and I can map it like this:
machinea.sp.com is http://sp1.sp.com:8080 : The machine that will function as a SAML2 Service Provider (SP)
machineb.idpproxy.com is http://openam.idam.com:8080/OpenAM-11.0.0 : The machine that will work as the SAML2 IdP Proxy
machinec.idp.com is http://idp1.idp.com:8080/OpenAM-11.0.0: The machine that will assume the role of a SAML2 IdP.
Each of these are set up as a Virtual box VMs on my Mac OS X.
My circle of trust is spcot instead of cot and realm is /sprealm.
The stack trace I get on the web page after submitting the changes is:
HTTP Status 500 -

Can anyone tell why this happens?
Thanks.
Your problem kicks off here:
at pwcms.GetRecommendations.doPost(GetRecommendations.java:41)
Looks like its trying to find a recommendation when there isn't one there - or an attribute of the recommendation is set to null when it shouldn't be. I'm 100% this isn't a tomcat issue. Try taking a peak in your database to check all the data is setup correctly.
looks like deployment issue. Or may be issue with tomcat.
Can you reinstall and try?
