Configure a connector for the port given in redirectPort. Update the Keystore path, password, and the server name in the file. Save the file.

    -Djavax.net.ssl.trustStore=<Adeptia Connect Truststore location)
    -Djavax.net.ssl.trustStorePassword=<Adeptia Connect Truststore password>

 How can I ensure that Tomcat is working fine?

To check the status of Tomcat, open the browser and type the URL in the below format:

<protocol_name>://<IP_address>:<port_number> 

where,

<protocol_name> is the name of the protocol you are using, for example, HTTP or HTTPS.

<IP_Address> is the IP address of the computer where Apache Tomcat 9 is installed.

<port_no> is the port number of the computer on which Apache Tomcat 9 is installed.

For example, http://192.168.1.1:80

The Tomcat welcome page appears, indicating Tomcat is running.

 Where can I view Adeptia Connect Logs in Tomcat?
  1. Go to …/<ApacheInstallFolder>/Tomcat<version_no>/logs.

    The URL format for app.adeptia.host.url is

    <protocol_name>://<IP_Address>:<port_no>

    where,

    <protocol_name> is the name of the protocol you are using, for example, HTTP or HTTPS.

    <IP_Address> is the IP address of the computer on which Adeptia Suite is running.

    <port_no> is the port number of the computer on which Adeptia Suite is running.

 How can I upgrade to latest Tomcat Version?

We don't recommend upgrading to Tomcat version. However, if required contact Adeptia Support as upgrading on your own can cause system failure.
