Configuring Tomcat to use a proxy server

Procedure

Stop your Tomcat server.

Set the configuration according to the way Talend Administration Center is run:

If you run Talend Administration Center as a server module.

Go to <TomcatPath>\bin, and edit the setenv.bat file. If the file does not exist, create it.

Add the following parameters, changing the parameters to match with your configuration:

set CATALINA_OPTS=%CATALINA_OPTS% -Dhttp.proxyHost=proxy.server.com # Specify the host name or IP address of your HTTP proxy server. You can use this parameter for http and https host names.
set CATALINA_OPTS=%CATALINA_OPTS% -Dhttp.proxyPort=YourHttpProxyPort # Specify the port number of your proxy server.
set CATALINA_OPTS=%CATALINA_OPTS% -Dhttp.nonProxyHosts="localhost|host.mydomain.com|192.168.0.1" # Specify a list of hosts separated by "|" that do not require access through your proxy server.

For example:

set CATALINA_OPTS=%CATALINA_OPTS% -Dhttp.proxyHost=proxy.server.com 
set CATALINA_OPTS=%CATALINA_OPTS% -Dhttp.proxyPort=3128
set CATALINA_OPTS=%CATALINA_OPTS% -Dhttp.nonProxyHosts="localhost|host.mydomain.com|192.168.0.1"

In case you use a proxy with authentication, go to <tomcat_path>/WEB-INF/classes/configuration.properties file and uncomment the following lines:
- proxy with the HTTP protocol:
```
#http.proxyUser=someuser
#http.proxyPassword=somepassword
```
- proxy with the HTTPS protocol:
```
#https.proxyUser=someuser
#https.proxyPassword=somepassword
```

If you run Talend Administration Center as a Windows service, change the Java properties using Windows command prompt:

Run the following commands:

<tomcat_directory>\bin\tomcat9w.exe //ES//talend-tac-x.x.x ++JvmOptions=-Dhttp.proxyHost=proxy.server.com
<tomcat_directory>\bin\tomcat9w.exe //ES//talend-tac-x.x.x ++JvmOptions=-Dhttp.proxyPort=YourHttpProxyPort
<tomcat_directory>\bin\tomcat9w.exe //ES//talend-tac-x.x.x ++JvmOptions=-Dhttp.nonProxyHosts="localhost|host.mydomain.com|192.168.0.1"

For example:

C:\Talend\7.3.1\tac\apache-tomcat\bin\tomcat9w.exe //ES//talend-tac-7.3.1 ++JvmOptions=-Dhttp.proxyHost=proxy.server.com
C:\Talend\7.3.1\tac\apache-tomcat\bin\tomcat9w.exe //ES//talend-tac-7.3.1 ++JvmOptions=-Dhttp.proxyPort=3128
C:\Talend\7.3.1\tac\apache-tomcat\bin\tomcat9w.exe //ES//tvalend-tac-7.3.1 ++JvmOptions=-Dhttp.nonProxyHosts="localhost|host.mydomain.com|192.168.0.1"

Restart your Tomcat server.
