Resolution

This issue is due to dependency for jaspersoft  i.e If we create any graph report and want to download in PDF format there is an dependency of Chromium.

 
Refer the below  url for more details 

https://community.jaspersoft.com/documentation/jasperreports-server/tibco-jasperreports-server-installation-guide/v900/jrs-install-guide-_-binary-installer-_-select-phantomjs/

We have identified three alternative solutions:

 

Solution 1

 Install Google Chrome and define chrome path in js.config.properties file 

 Please follow the below steps to resolve the issue 

-- Navigate to Nimsoft_Install_Dir\probes\service\wasp\webapps\cabijs\WEB-INF and take back up of js.config.properties

--  Open js.config.properties file and edit  for chrome.path = as below 

chrome.path=INSTALL_DIR//Google//Chrome//Application//chrome.exe

or 

“INSTALL_DIR/Google/Chrome/Application/chrome.exe "(replace \ with  /).

Restart the robot and verify 

Note1: In case Chrome browser is not installed we need to install Chrome Browser on CABI  Robot and chrome browser is not required on any other machine for this to work

Note2 :Above solution will work even if you use Edge browser as it uses chrome internally and you don't need to specify the Edge browser executable path in js.config.properties

 

 

Solution 2 :

Download chromium and provide path in the js.config.properties file

Chromium download link   -  https://www.chromium.org/getting-involved/download-chromium/

Edit chrome.path =  Chromium-download-dir//chrome.exe

Restart the robot and verify 

 

 

Solution3:

Apply the hotfix provided in KB attachments 

JS 8.2.0 Hotfix (Readme) and hotfix CABI_Scheduler_Hotfix.zip 

Note1 :Solution 3 will be applicable only on windows CABI Environment

Note2: Please revert the js.config.properties to its original value before applying this hotfix i.e keep the chrome.path in js.config.properties empty

 

 

Additional Information

Solution 1 ,2 and 3 is only applicable on windows environment with cabi 23.4

If we deploy any CABI build post 23.4  like (23.4 Cu2) we need to reapply the above solutions /Hotfix
