Very new to Hawtio and Jolokia. I am NOT using JBOSS or any other RedHat product, only Tomcat. I downloaded Hawtio-default.war (ver. 1.4.21) and Jolokia.war (ver. 1.2.2). I have two Tomcat (7.0.39) instances on my local machine (localhost), running on port 18080 and 38080 respectively.
The issue: If I didn't enable the security for Jolokia, I was OK to connect from Hawtio (port 18080) to Jolokia (port 38080) without any problem. However, if I enabled the security for Jolokia, I was NOT able to connect and always got below error (tried in both FF and Chrome):
This is the details of I have done:
1. Deployed Hawtio.war to Tomcat running on port 18080.
2. deployed Jolokia.war to Tomcat running on port 38080.
3. Without enabling security for Jolokia, I was able to connect from Hawtio (port 18080), without proxy, to Jolokia (port 38080). Success.
4. Then, I tried to enable security for Jolokia by uncommenting the section in its web.xml to make it look like this:
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>UserDatabase</realm-name>
</login-config>
<security-constraint>
<web-resource-collection>
<web-resource-name>Jolokia-Agent Access</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>Jolokia</role-name>
</auth-constraint>
</security-constraint>
<security-role>
<role-name>Jolokia</role-name>
</security-role>
and in tomcat/conf/user-tomat.xml file, I added:
<role rolename="Jolokia"/>
<user username="admin" password="hawtorwhat" roles="Jolokia"/>
- Add username/password and role to tomcat-users.xml file as:
- restarted both Tomcat instances.
- Tried to goto Jolokia directly
http://localhost:38080/jolokia, it prompted me for username and password. After I typed in admin and hawtorwhat, I was shown below message in my browser. So it looked like OK to directly remote connect to a security-enabled Jolokia. - launched
http://localhost:18080/hawtio, clicked on "Connect" tab, provided same info plus username and password for localhost port 38080 (without proxy), un-success. the error was always the same (different error for different browser, strange, no previous hawtio plug-in for Chrome):
In FireFox:
Cannot Connect: [Exception... "Failure" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: http://localhost:18080/hawtio/app/app.js?6f7be3a9a9f2ffe8 :: .send :: line 8" data: no]
In Chrome:
Cannot Connect: NetworkError: Failed to execute 'send' on 'XMLHttpRequest': Failed to load 'http://localhost:38080/jolokia-war-1.2.2/?maxDepth=2&maxCollectionSize=500&ignoreErrors=true&canonicalNaming=false'.
I also tried check 'use proxy', it didn't work regardless with or without security enabled. Error message was as:

My IE (ver. 9) doesn't seem to support html5, leave it out for now...
I read docs and others internet posts for both Hawio and Jolokia, not sure what I missed. Based on #3 and #7 above, Jolokia seemed to be running fine. What else should I do? Is any config or additional files that I need to add anywhere? Please help. Also, how am i going to debug this?
Thank you,
