Why Linux app is mapping paths from Windows like this one:

I installed java 11. It is not well explained what dependencies it needs. Can someone installed it on Ubuntu 20.04?

Try to remove extracted folder and repeat installation again.

I am getting problem on "credit card C app whatever" complaining about one lost log. I removed app folder and extracted again and it works.

you must run linux app using sudo ./weblauncher.sh.

Locate this script in webapp folder.

chmod a+x sudo weblauncher.sh

sudo ./weblauncher.sh

Hi Sir ,

I run sudo ./weblauncher.shand still run into the same issue .

First of all why does it look for Websphere in my local (C:\Program Files\IBM\WebSphere MQ\java\lib) . Please see the exception below . (Note :I have installed the EasyTravel on Ubuntu 20 linux ). Appreciate your help. Thanks

Hi Everyone

I had the same error: "WebLaunche WARN [DocumentStarter] Exception occurred while opening URL: http://localhost:8094/. Exception: Cannot run program "firefox": error=2, No such file or directory"

My Fix:

I figured that firefox was not install on my VM. I ran "yum install firefox" (as root) then relaunched my weblauncher "./weblauncher.sh" and the error stopped popping up. Hope that helps

Hi there. I know this is an old thread to dust off, but I am having the same error as the person who you replied to (Walter2) and I would appreciate any help I can get.

My scenario is effectively identical. I am on Ubuntu Server 22.04. The installation of easyTravel worked perfectly on a fresh build with java 11. After extracting the .jar file without issue, I did "/bin/bash installChromeDeps.sh" in the RESOURCES directory. Again, no problem.

It's when I attempt to invoke ./weblauncher.sh that I get I get the same failure as above:

Hi for your issue you will need to keep the terminal runing on weblauch command and open the browser on your easytravel machine then access the link localhost:8094 if you are logged from another machine use the specific ip address of your easytravel machine with the port 8094.

be aware to allow the ports used on your easytravel machine such 9080 8079 8080 8094
