Hawtio/Jaas ldap login

trying to add in authentication to hawtio using JAAS by following the configuration docs
Started by using jetty's demo-base test-jaas war to configure a basic JAAS/jetty login and was able to authenticate/authorize.
Tried to incorporate the same concept into hawtio by reading the docs but I'm convinced that it doesn't even seem to reach out to ldap since when I tried this with the demo war I would get logs like "found user? true"
.
I've decided to just ignore authorization for now and just try to authenticate with ldap. If anyone has any suggestions on what I can try to do to debug this further, I would appreciate it.
Here's my realm config:
hawtio {
org.eclipse.jetty.jaas.spi.LdapLoginModule required
debug="true"
useLdaps="false"
contextFactory="com.sun.jndi.ldap.LdapCtxFactory"
hostname="10.10.10.10"
port="389"
bindDn="asfd#test.com"
bindPassword="asdf"
authenticationMethod="simple"
forceBindingLogin="false"
userBaseDn="cn=Users,dc=test,dc=com"
userRdnAttribute="cn"
userIdAttribute="sAMAccountName"
userPasswordAttribute="userPassword"
userObjectClass="user"
roleBaseDn="cn=Schema Admins,cn=Users,dc=test,dc=com"
roleNameAttribute="name"
roleMemberAttribute="member"
roleObjectClass="group";
};
some of the web.xml for hawtio regarding jaas/authentication/roles:
<env-entry>
<description>Enable/disable hawtio's authentication filter, value is really a boolean</description>
<env-entry-name>hawtio/authenticationEnabled</env-entry-name>

</env-entry>
<env-entry>

and some of the logs i'm looking at

This is more of a workaround solution, but finally got hawtio to be configured by using a different ldaploginmodule
Must be some sort of configuration with the org.eclipse.jetty.jaas.spi.LdapLoginModule class.

java.lang.ClassNotFoundException: org.eclipse.jetty.server.Request when starting with jetty:run-forked and connecting with ssl

I'm using jetty's pushbuilder to push some resources. As these resources are specified from inside the webapp, i can't use jetty's default pushCacheFilter.
When i start jetty embedded from my main java-class, it works well, i can connect to my page with https and also the push works fine.
But when i start via jetty:run-forked, it starts and gives this output:
**Started ServerConnector#45b4c3a9{SSL,[http/1.1, ssl, alpn, h2]}{0.0.0.0:8443}**
And then when accessing the page i get this error:

Maybe it's sth. with the maven classloading?
Edit
Another error occurs: Some of my latest Code-Changes seem to be missing after the maven-build. I've tried to just run "maven clean", but there are still missing fields and an exception is thrown.
These fields also are found, when starting jetty embedded.
Thx a lot!

After reading the jetty-docs again i found the reason:
server-classes are hidden from the webapp if jetty is the servlet-container. So this was my fault, the exception had to be thrown!
(see the docs here: http://www.eclipse.org/jetty/documentation/9.4.x/jetty-classloading.html)
I think the other missing-field-exceptions were related to this "forbidden" import.
So i think my problem is another one:
How can the (jetty-specific) serverPush can be realized, when it's not sure, that my webapp is deployed in jetty??
Jetty's own solution (pushCacheFilter.java) doesn't fit my needs.
So i guess i have to check, if i can write a filter that works in the moment when jetty sends the response.

We thought we avoid that issue if we update Jetty libs but issue still reproduces.
We use Jetty 9.4.

I guess you are using the old version of asm.jar with newer compiled Java bytecode.
For Java 8 bytecode, use asm 5.0.1+
See Strange java.lang.ArrayIndexOutOfBoundsException thrown on jetty startup
Dont't forget to update cglib.jar to a proper version because it has the asm as a dependency

My query is as follows
MATCH (place:Place)<-[:IN]-(event:Event {id:'29_jun_2'})-[]-(chat:Chat), (user:User {id: 'NJE86-jRe'})
OPTIONAL MATCH (event)-[:CHKIN]-(friendchkin:User)-[:FRIEND]-(user)
WHERE NOT (friendchkin)-[:BLOCK]->(user)
return event, chat, user, COLLECT(distinct friendchkin) AS friendschkin;
When I comment out the part after OPTIONAL MATCH the query works fine, but gives error included back in. In browser console I get event,chat,user as expected and COLLECT returns an empty Array.
Also will mention that No Error stack trace shows up in Neo4j console when running NodeJS application, error only shows up at the NodeJS Server terminal.

Install ActiveMQ on CentOS cannot open admin and other webpages

I am installing ActiveMQ 5.13.1 on CentOS 6.7. I am fellowing this tutorial: https://rburnham.wordpress.com/2012/09/14/installing-and-managing-activemq-on-centos/.
I almost fellow the steps, now I can access
http://xxx.xxx.xx:8161/ from remote client, it shows "Welcome to the Apache ActiveMQ!" page, but once I open http://xxx.xxx.xx:8161/admin, error appears:
HTTP ERROR 500
Problem accessing /admin/. Reason:
Server Error

Actually some steps I cannot achieve:
sudo /opt/activemq/bin/activemq-admin list
It said there is no activemq-admin.
After I do :
sudo /opt/activemq/bin/activemq setup /etc/default/activemq
/etc/default/activemq is not created. so I cannot do:
sudo chown root /etc/default/activemq
and
sudo chmod 600 /etc/default/activemq
I also fellow another answer( ActiveMQ console not available ) change the config file from
<import resource="jetty.xml"/>
to
<import resource="${activemq.base}/conf/jetty.xml"/>

I also faced same problem after installing maven , for workaround did uninstall maven and perform the below steps.
Tried to reinstall activemq .
brew reinstall activemq.
after this restart the system as well.
