How to map different Tomcat 9 applications to different URLs? - tomcat9

I have a Tomcat 9 server with two applications installed on it: "App1" and "App2". Obviously, these applications are accessible using these two URLs:
http://my_xyz.com/App1
http://my_xyz.com/App2
I need to be able to access the first application using the URL:
http://other_xyz.com/
and the second application using:
http://yet_xyz.com/
It is required NOT to use a web server in front of it. Only the Tomcat 9 server should be configured.
Remark that "App1" and "App2" does not appear in the new URLs. Tomcat virtual hosts is the solution, but how can I hide the applications names?
Thanks

As you remark in your post you just need to:
create two virtual hosts:
<Host name="app1.example.com" docBase="webapps/app1.example.com">
...
</Host>
<Host name="app2.example.com" docBase="webapps/app2.example.com">
...
</Host>
Once the virtual hosts are configured, you can independently add applications to each one of them. Most importantly you can have two applications with an empty context path (one for each host). E.g. you can move the WAR file of the first application to webapps/app1.example.com/ROOT.war and the second one to webapps/app2.example.com/ROOT.war (or use any of the other ways to deploy an application).

Making nextcloud work on a prefixed path (using docker and caddy)

I'm trying to setup my own instance of nextcloud on my server but I'm running into a problem as I want nextcloud to be available under https://example.com/cloud/.
Next cloud is running in a CoreOS virtual machine called let's say myvm.
So this is the way I setup my CaddyFile:
example.com {
gzip
proxy /cloud myvm:8080 {
transparent
without /cloud
}
}
I have other proxies that work fine for other services or VMs that are written similarily.
With this, and publishing port 8080 in my docker-compose file, I manage to connect to the nextcloud instance. But every time I go to example.com/cloud/ it will redirect me to example.com/apps/files/ instead of example.com/cloud/apps/files/.
If I enter this last url manually, I can access to nextcloud, but also the page doesn't load properly because all the contents cannot be loaded because they are not prompted with the prefix cloud/.
Is there a way to explain nextcloud about this prefix through the configuration of docker-compose file? (It's the only configuration I created, it works with just that and no extra work, I use one similar to the one available here (the apache one).)
Or maybe I can improve the CaddyFile config? (By the way, if I don't use the without option, it will just not work at all and return 404 when I go to the url).

How to change default start page of Glassfish?

Currently when I type in the URL of my webapp, say "http://abc.edu/mywebapp/", I am taken to the login page of my webapp. When I type "http://abc.edu/", I am taken to the GlassFish info page. How can I do it such that when I key in "http://abc.edu/", I will be taken to my login page and not the GlassFish info page?
Option 1: You can set one of your webapps as default. This can be done with the admin console:
Configuration --> Virtual Servers --> server
Then select your default web application from the drop-down menu. If your webserver port is 8080, you can start your application now by:
http://hostname:8080
instead of http://hostname:8080/webapp
Notice that "server" is the name of Glassfish's default virtual server. If you configured a different virtual server for your webapp you need to change it accordingly.
Furthermore regarding this source, there might be some problems with JDBCRealms.
Option 2: You could also deploy your default webapp to "/" instead of "/webapp" but I think the first option is more flexible.
You need to change your context root to "/" Edit the application.xml that is where the context root for the app is set. You might have to undeploy the default context root inorder to do that (that is what I do in JBoss, I undeploy ROOT.war).

using old port after chaging domain.xml

I am using Glassfish V3 which comes with netbeans only , as there are few servers running on my pc , i have changed the port from 8080 to 8787 of glassfish v3 by altering domain.xml
<http-listener id="http-listener-1" port="8787" address="0.0.0.0" default-virtual-server="server" server-name="" />
<http-listener id="http-listener-2" port="8181" enabled="false" address="0.0.0.0" security-enabled="true" default-virtual-server="server" server-name="">
Now when i deploy the restful webservies over server or click on Test Restful Webservice in netbeans
i am getting a page in a browser which still uses the old port and even there is not webservice option get displayed on it the page is blank. here is the screen shot
note: i tried restarting it may times but still using the old port
In your Netbeans project node there must be a sub node like "Generated sources (rest-test)" or similar (I don't have Netbeans in english).
If you expand this node, there must be a file named test-resbeans.html. Open this file and check the following entry:
var baseURL = "http://localhost:8080/MyFirstWebService/||/resources";
The term MyFirstWebservice needs to be replaced by your services's name.
Change the port there if necessary.
There was an open issue for something similar. I fixed it a while back, but the change will be in NB 7.0. I do not think anybody will backport the change into 6.7... but you never know.

ASP.Net MVC 2 on nginx/mono 2.8

I am trying to setup ASP.Net MVC 2 application on Linux environment. I've installed Ubuntu 10.10 on VirtualBox, then installed Mono 2.8 from sources. After that I have installed nginx and configure it as recommended here.
Unfortunately, FastCGI shows me standard error 500 page:
No Application Found
Unable to find a matching application for request:
Host localhost:80
Port 80
Request Path /Default.aspx
Physical Path /var/www/mvc/Default.aspx
My application is located in /var/www/mvc directory. I've tried to create some stub Default.aspx file and place it in root dir of my application, but it didn't help, same error occured.
Thanks.
I've been doing some testing with this as well, using all ubuntu10.10 binaries.
From what I can make from it, either nginx fails to pass the hostname of the mono server fails to receive it over the fastcgi protocol. Anyhow, the tutorial line:
fastcgi-mono-server2 /applications=www.domain1.xyz:/:/var/www/www.domain1.xyz/ /socket=tcp:127.0.0.1:9000
doesn't work. Removing the hostname makes the thing work:
fastcgi-mono-server2 /applications=/:/var/www/www.domain1.xyz/ /socket=tcp:127.0.0.1:9000
but this of course blocks the use of multiple virtual mono hosts.
Since you are running ASP.NET MVC 2 application you should use fastcgi-mono-server4.
Adding following line in /etc/nginx/fastcgi_param resolves the issue for me. It also allows to use multiple virtual hosts.
fastcgi_param HTTP_HOST $host;
Does your application work with xsp (xsp4 if you are using .net 4.0)? You'll want to make sure that is working before you try configuring the connection to another web server.
Does nginx know where to find mono? You most likely have a parallel install and it won't be in the default paths.
I use apache, but you may still find some of the instructions on my blog useful:
http://tqcblog.com/2010/04/02/ubuntu-subversion-teamcity-mono-2-6-and-asp-net-mvc/
I had this problem just now, I too had been following the document on the mono site:
I was trying to start the fastcgi-mono-server as it suggested:
sudo fastcgi-mono-server4 /applications=www.domain1.xyz:/:/var/www/www.domain1.xyz/ /socket=tcp:127.0.0.1:9000 &
However when I did it like that I got the same problem as you. I changed it to this:
sudo fastcgi-mono-server4 /applications=/:/var/www/www.domain1.xyz/ /socket=tcp:127.0.0.1:9000 &
And it worked ( I had to type in www.domain1.xyz/Home/Index to see my MVC page, not worked out how to stop it looking for www.domain1.xyz/default.aspx yet XD ).
You need to make sure the domain set in your site config matches the domain passed to the fastcgi server. So for example if your default site (/etc/nginx/sites-enabled/default) has the following config:
server {
...
server_name www.domain1.xyz;
...
}
You would need to pass that domain into the fastcgi server:
sudo fastcgi-mono-server4 /applications=www.domain1.xyz:/:/var/www/www.domain1.xyz/ ...
Then when you access the site it will obviously need to be with that domain you set.

How to run multiple instances of JBoss in a one single machine?

I need to run multiple(more than 4) instances of JBoss server on a single machine.
I am using JBoss 4.2.3 GA.
I found the answer. We have to configure the jboss-service.xml to run multiple instances in the same machine.
We may need to keep the same "default" instance same as it is under the JBOSS_HOME\Server.
We have to create another folder say "instance2" under JBOSS_HOME\Server.
Copy all the contents from JBOSS_HOME\Server\default to this newly created folder.
Now goto conf folder under JBOSS_HOME\Server\instance2 directory.
Edit the jboss-service.xml.
Search for mbean code="org.jboss.services.binding.ServiceBindingManager" in this configuration file.
By default this xml tag is commented. We have to un comment it and change the value ports-00 to ports-01.
Then start this instance2 jboss instance. We can access this application by using the port number 8180.
We can go for at maximum of 3 instances with this way.
To run more than this we have to add some more running tags in
JBOSS_HOME\docs\examples\binding-manager\sample-bindings.xml.
You can make things a lot simpler by simply changing the IP that the server is bound to.
You will need to copy the entire jboss folder several times and configure run.bat to use the -b parameter on startup.
If this is a Windows server and you're running jboss as a service, you might want to edit the service.bat for each instance too so that the servers all have different names in the services control panel.
Part of the problem we ran into when trying to use different HTTP ports was that jboss uses 'lots' of ports for different purposes and it was a pain to edit all of these port numbers to be unique on each instance. By changing the bind address you can avoid this problem entirely.
Create multiple loopback adapters and bind each ip address to different instance.
No need of changing port.
RK
1) Copy the default folder with new name: instance name
2) In jboss-service.xml Uncomment the ServiceBindingManager mbean and change the ServerName to ports-01 or 02 or 03 e.g:ports-01 and ports-01/02/03 configuration should be there in sample-bindings.xml(present in docs/examples/binding-manager) And make the changes in all the ports mentioned under ports-01/02/03 tags, So that ports will not get conflict. Remember the server will run on the binding port like 8080/8180/8182.
from cmd promt go to the bin folder and run the instances with cmd:
run -c instancename
Running multiple instances of JBoss on the same server:
We should keep the "default" instance same as it is under the **JBOSS_HOME\Server
Copy the default folder with new name (instance name) say default2 under JBOSS_HOME\Server. Copy all the contents from JBOSS_HOME\Server\default to this newly created folder.
The binding service manager needs to be enabled in conf/jboss-service.xml for instances that are not using the default ports.
a. (i.e.) In the copied instance, go to conf folder under JBOSS_HOME\Server\default2 directory. Edit the jboss-service.xml.
b. Search for mbean code="org.jboss.services.binding.ServiceBindingManager" in this configuration file.
c. By default this xml tag is commented. We have to uncomment it and change the value ports-00 to ports-01.
In the same file, Under "Socket transport Connector", in the "Configuration" section, serverBindPort must be changed to another value or it will conflict with the default (4446).
<mbean code="org.jboss.remoting.transport.Connector"
name="jboss.remoting:service=Connector,transport=socket"
display-name="Socket transport Connector">
...
<attribute name="Configuration">
...
<attribute name="serverBindPort">25447</attribute>
...
In default2/deploy/ejb3.deployer/META-INF/jboss-service.xml, for the remoting.transport.Connector mbean, port 3873 must be changed to another value or it will conflict with the default.
<mbean code="org.jboss.remoting.transport.Connector"
name="jboss.remoting:type=Connector,name=DefaultEjb3Connector,handler=ejb3">
<depends>jboss.aop:service=AspectDeployer</depends>
<attribute name="InvokerLocator">socket://${jboss.bind.address}:25874</attribute>
...
In default2\deploy\jboss-web.deployer\server.xml
set redirect port value to the one configured in step 4
<Connector port="8180" address="${jboss.bind.address}"
maxThreads="250" maxHttpHeaderSize="8192"
emptySessionPath="true" protocol="HTTP/1.1"
enableLookups="false" redirectPort="25447" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true" />
Also, the port value configured in step 5
<!-- Define an AJP 1.3 Connector on port 8009 -->
<Connector port="25010" address="${jboss.bind.address}" protocol="AJP/1.3" //change the connector port value to avoid conflict
emptySessionPath="true" enableLookups="false" redirectPort="25874" /> // port value configured in step 5
In summary, the directory structure for setting up two other instances would be something
like the below with modifications in the filenames in bold.
$JBOSS_HOME/server/default
$JBOSS_HOME/server/default2
$JBOSS_HOME/server/default2/conf/jboss-service.xml
$JBOSS_HOME/server/default2/deploy/ejb3.deployer/META-INF/jboss-service.xml
$JBOSS_HOME/server/default2/deploy/jboss-web.deployer/server.xml**
$JBOSS_HOME/server/default3
$JBOSS_HOME/server/default3/conf/jboss-service.xml
$JBOSS_HOME/server/default3/deploy/ejb3.deployer/META-INF/jboss-service.xml
$JBOSS_HOME/server/default3/deploy/jboss-web.deployer/server.xml**
7.From command prompt go to the bin folder and run the instances with cmd:
run -c instancename
In this case, it is: run -c default2
And applications accessed with url’s like:
http://localhost:8080/myapp/
http://localhost:8180/myapp/
http://localhost:8280/myapp/
Note: We can go for maximum of 3 instances with this way.
To run more than this we have to add some more running tags in JBOSS_HOME\docs\examples\binding-manager\sample-bindings.xml.
I used this article to install mine.
http://wiki.adempiere.net/Setup_2_Adempiere_JBoss_server_in_1_physical_server
You should create different services to control the adempiere servers.
Also if you work with jasper report, use unique file names for reports or you will face permission denied exception.
Ex : if you attach "report.jrxml" to two servers. Server will create /tmp/report.jrxml tmp file.
The second server will also try to create the same file and get crashed
Copy complete JBOSS setup to new location, and start new server with offset option, which will start server on existing ip and changing port to previously_configured_port+offset
standalone.bat -c standalone-full.xml -Djboss.socket.binding.port-offset=100
This command will make default jboss console 9990 to 10090
Now you can add your war file in new deployments folder and start deployment on new port
The quickest and easiest way that comes into mind is simply configuring multiple IP addresses to the hosting machine. Then you can use the different IP addresses to bind to each instance. Doing this means you don't have to change any default ports and allows for an easier environment to manage.
We can easily do this on JBOSS EAP
For first instance, just start the JBOSS as it is.
for the second instance,
Copy the JBOSS home folder to a different location.
go to standalone/configuration/standalone.xml. go to the section(at bottom of the file) and set port-offset value to some value(EX: 10000) which doesn't have any port binding issue on currently running application. Here the default port-offeset value is 0.
start the second instance as usual .
