I'm trying to connect JVisualVM, running on my local machine, to a remote machine which is running a WildFly server (version 8.1.0, to be specific.)
I didn't configure the WildFly server myself, and I don't know who did, but I do know that I can log in as an administrative user from my local machine by pointing my browser at:
https://[ip address of the remote machine]:9443/console
Note that it's https, not ordinary http, and that the port for that has been set to 9443 (I think the default is 8080 or 9990 or something... IDK, I saw a lot of port numbers online. I have been explicitly told that http was disabled for this WildFly server).
I can SSH into the remote machine. I can navigate to the bin directory for WildFly and run jboss-client.sh. I have to connect on port 9999 (I think the default is 9990 for that?)
I copied the jboss-client.jar (under bin/client) to my local machine and ran JVisualVM from the command line like this:
.\jvisualvm.exe -cp:a C:\[path to]\jboss-client.jar
It launches fine. File > Add Remote Host: Then I entered the IP. OK. I right clicked on it under Remote in the tree and picked Add JMX Connection. I entered
service:jmx:http-remoting-jmx://[ip]:9999
I checked off that I wanted to use the security credentials and entered the username and password. Checked off to save the security credentials. Left "Do not require SSL Connection" unchecked. Hit OK. It immediately spat out the message
Cannot connect to admin#service:jmx:http-remoting-jmx://[ip]:9999 using service:jmx:http-remoting-jmx://[ip]:9999
I also tried the port 9443, 9990, and 8080 instead. None of those worked. I tried https instead of http in the protocol name. That also didn't work.
What am I missing? How is it that I can access the console, and connect with jboss-client.sh, but I can't use JVisualVM? Is there some log I can use somewhere to see what's wrong? Maybe someone can point out a configuration I've missed somewhere?
Not sure if it's important or not, but my local machine is running Windows 10 with JDK8 installed. The WildFly server is using Java 6 on CentOS 6.3.
You need to add the jboss-client.jar (or jboss-cli-client.jar) to the class path for JVisualVM. The library can be found in the bin/client directory of the WildFly install.
I used the following command to add the library to the class path.
jvisualvm --cp:a ~/servers/wildfly-10.0.0.Final/bin/client/jboss-client.jar
Then I used service:jmx:remote+http://[ip]:[port] and was able to connect.
I don't know if someone else is also (still) having the same issue (Wildfly10 on a remote machine where management console is available at 9443 with HTTPS). The following worked for me.
For ssh connections:
Starting jvisualvm with jboss-client.jar
jvisualvm --cp:a #JBOSS_HOME/bin/client/jboss-client.jar
Using the following connection string:
service:jmx:remote+https://remote-server:9443
NOTE: I used here remote+https
Provide username and password
Hope this helps.
you missed run jstatd command in remote host ,
this little program is RMI server that possible connection from client to remote host though you using jmx connection it used jmxrmi protocol for that connection .
so first in remote host create file name as security.policy with this contain :
grant codebase "file:${java.home}/../lib/tools.jar" {
permission java.security.AllPermission;
};
off course you must in file section for linux put explicit path and then of creation this file put it in bin directory of jdk.home
then you should run this command on remote host
$JAVA_HOME/bin/jstatd -J-Djava.security.policy=path of /security.policy -J-Djava.rmi.server.hostname=remote ip address -J-Djava.net.preferIPv4Stack=true
then you could connect to server off course with correct settings.
Include jboss-cli-client.jar and jboss-client.jar under \lib\visualvm\platform\lib and restart jvisualvm to pickup new jars.

To load some code, I need a clean local AEM Author instance running on my laptop. I start it using CLI like :
bash$ java -jar aem-author-p4502.jar -nointeractive
Default user/password is then admin/admin to access AEM on http://localhost:4502. I'm ok with that but I've tested from another computer and port 4502 is open from full local network.
I'd like to limit access only from localhost, maybe by configuring listener address to 127.0.0.1 only. How ?
Recent AEM versions uses Apache Felix Lightweight HTTP Service as HTTP Server. I found how to bind it to 127.0.0.1 when it is embedded in AEM.
Configuration file is crx-quickstart/launchpad/config/org/apache/felix/http.config. I added last line :
:org.apache.felix.configadmin.revision:=L"1"
org.apache.felix.http.session.timeout=I"10"
org.apache.felix.https.jetty.protocols.excluded=[ \
"SSLv3", \
]
org.apache.felix.proxy.load.balancer.connection.enable=B"true"
service.pid="org.apache.felix.http"
org.apache.felix.http.host="127.0.0.1"
Now AEM Author is available only from localhost.
Maybe you can try to add an exception on your firewall to the port 4502 and only enable connections from your local and deny the others.
Regards,
I tried almost all internet and stackoverflow tips and no one didn't help me to open ports in Weblogic Server. My Weblogic server starts as windows service in windows server 2008 r2. In config.xml on the path
..user_projects\domains\%Any_app%\config\config.xml i added this string for each server in arguments -
<server-start>
<arguments>... -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=1777,server=y,suspend=n ...
</arguments>
</server-start>
and i always check in cmd with netstate -a or telnet this port but it doesn't appear and doesn't work.
For the first, check your firewall - ensure that port is open.
Second, check config.xml again, then in administration console go to
Servers - Configuration - Listen Port - made modifications if needed.
Restart weblogic. Check if service is started, if not then modify windows service.
Read this article how to manage ports.
Change the port number with WLST, if it possible for you.
For me the solution was to edit regedit with my weblogic as win service. Path:HKEY_LOCAL_MACHINE/SYSTEM/services/%Name_of_service% and here u can edit settings
(add some strings in setting fields) and then restart machine with u server.
I was implemented two different servlets in two different web projects in netbeans using tomcat server. When try to run html file for one servlet in one project it running, but when trying to run another servlet in second project the following message appear in browser. This site cannot be reashed in localhost 8080 and localhost refused to connect.
I try to solve it by following steps in cmd:
1-ipconfig /release
2-ipconfig /all
3-ipconfig /flushdns
4-ipconfig /renew
5-netsh int ip set dns
6-netsh winsock reset
and try close proxy and windows firwall but the problem is still.
You are trying to serve requests with 2 programs in the same port, which can't be done. What would you expect it would happen if you went to localhost:8080? Both of them would be serving requests in that port, so the OS doesn't allow it.
You can go to tomcat>conf folder in one of the projects, and edit the server.xml file.
There should be a line saying Connector port. Replace "8080" for other port, for example "8081" and start tomcat.
I cannot have my tomcat server started and at the same time use internet.
either I can start Tomcat (in Eclipse) and internet is not available.
or I can access the internet but tomcat cannot be started.
Here the original probleme I had when I first wanted to use Tomcat and display my html page on localhost.
GRAVE: StandardServer.await: create[localhost:8005]: I find a way to start the Tomcat Server: in the terminal:
sudo lsof -i : 8005 # checks port 80
sudo route -n flush
sudo route add default 192.168.1.1
then I can use tomcat and localhost:8080 but my internet connexion is dead
if I want my internet connexion then I stop the tomcat server by clicking on the red square in eclipse and then in the terminal I do:
sudo route -n flush
sudo route add default 192.168.0.1
THen I can use internet but tomcat cannot be restarted. I have to undergo the first process.
this of course is a very boring process and I would like to know what 's wrong and how I could fix it.
I use tomcat 9 / Mac OS sierra / Eclipse Neon3
When you say "my internet connexion is dead", do you mean that your network connection drops or that your DNS lookups fail? (What do you think this command is doing and why are you performing it: sudo route add default 192.168.1.1?)
If your program is modifying your system's connectivity settings, I would strongly recommend against preventing it from doing that. There's no reason for it to do so at that level, a more appropriate place to set settings would be at some deploy stage.
Alternatively, you could run your app in a Docker container which I strongly suspect will solve your problem. Visit www.docker.com to learn more.
I'am installing ArcGisServer for the Java plataform on Centos 5.5 x86_64, this is not a supported platform but I have overcome almost every problem preventing the success of the installation. It uses exhaustively Sun Directory Server. The last error i receive was:
ldap_simple_bind: Can't connect to the ldap server - No route to host
It happens in other applications which makes uses of it, so it seems to be an specific problem of Sun Directory Server on linux and solaris. There is no reported solution. Usually I search the problem as much as I can but this time I have reached my patience and I need it working as soon as posible. I recognize this as an excellent forum because of it's community and quality of answers, ¿can anybody help me with this?
The "No route to host" error suggests that the issue is one of network connectivity between your ArcGIS server (the Sun Directory Server component, as you mention) and the LDAP server. So, a few things to examine, in order:
Do you have an LDAP server set up and running?
Is your LDAP server reachable from your Centos machine outside of the ArcGis server?
Is your ArcGis configured with the correct address to the LDAP server - should be in the web.config file? Example below:
<connectionStrings>
<add name="ADConnectionString"
connectionString="LDAP://SERVER_LDAP:389/ou=Sigestredi,o=Sicondef,dc=aplicaciones,o=mdef,c= es" />
</connectionStrings>
Disclaimer: I don't know anything about the ArcGIS server per se - I'm just diagnosing the "no route to host error" with a few snippets I picked up from some quick searches of the ArcGis forums.
ArcGIS includes a Sun Directory Server on it, so arcgis server and ldap are on the same machine. The port is set to 62000. When I run the diagnostic tool the DG028 fails:
DG028 - check LDAP server: is listening
I made a prove using nmap as:
nmap localhost -p62000
And it says it is opened. I don't know how to verify if LDAP is up and running, the startup log doesn't show anything wrong. I have found a config file named ldap.conf:
url ldap://name.subdomain.domain:62000/dc=name,dc=arcgis
admnm agsadmin
And my /etc/hosts is:
127.0.0.1 localhost localhost
ip_direction name.subdomain.domain name.subdomain.domain
I don't have an alias for "name", so:
ping name.subdomain.domain
Works
But:
ping name
Doesn't work
I have never used ldap so I don't know what should be on "dc". Could my hosts file be malformed or is my ldap.conf?
Another information is that the computer I am using is part of a domain. When I installed Centos, /etc/hosts file had an alias for the loopback interface as localhost.localdomain but i removed it.
I would appreciate any help.
I have solved my problem, the problem was on my /etc/hosts file. I added an alias for my ip direction:
127.0.0.1 localhost localhost
ip_direction name.subdomain.domain name
Then I run the ServerConfig script. This is a successful installation of ArcGIS Server for the Java platform on Linux. Thanks Greg for your guide.
