TimeoutException when try to Export Dashboard to PDF

[sanidu_lakmal]

After trying the steps stated in Link

In my local Environment

Java 8 , Jasper 8, Windows 11

Now I can export a dashboard report using Screenshot -> PDF.

 

But in remote environment (uses docker), it failed with Timeout exception.
In Js.config.properties, chromium path is set

chrome.path=/usr/lib64/chromium-browser/chromium-browser.sh

and I try increasing timeout (chrome.page.timeout) but I does not fix the issue.

and I also tried the solutions suggested here but no success.

Here are the logs

Hi, 

I am combining both the solutions provided by our team here.

1. In WEB-INF/applicationContext.xml
 
<prop key="net.sf.jasperreports.chrome.argument.enable-logging">stderr</prop>

Add below 2 properties after the above property in the file, if these don't exist.
 
<prop key="net.sf.jasperreports.chrome.page.isolate">true</prop>
<prop key="net.sf.jasperreports.chrome.argument.remote-allow-origins">*</prop>

2.

In WEB-INF/js.config.properties:

Put your server URL with correct domain apart from local URL.

deploy.base.local.url=https://localhost:8443/jasperserver-pro
deploy.base.url=https://{domain}:8443/jasperserver-pro

--Example http://bi.example.com/jasperserver-pro for deploy.base.url

And in WEB-INF/classes/jasperreports.properties add the following:

net.sf.jasperreports.chrome.argument.ignore-certificate-errors=true 
 

**make sure to use http or https appropriately. 
These changes require a restart of the JR server.

As the issue is repeating with dockerized setup, need to make sure all these are correctly set and remote JRS is restarted after all these change.

I tried the solution suggested by jmand.
The only new thing I have done is adding deploy.base.url.

Other options are already there.

but unfortunately it does not fix the issue. (I redeployed them on remote, So the JR server is started fresh with those changes)

[Jitendra Mandalia]

I don't see why it shouldn't work now. Can you recheck the chromium path? The usual location for Chromium in Linux is /usr/bin/chromium-browser... 

If there is any issue with the path then correct it and restart the server and try. If the given path is correct, then I will try to verify a few things to see if the issue is identifiable. As this seems to be specific to your environment.

HI jmand , arai_4 

Sorry for the late reply.
Path to chromium executable is correct.

 

PS : I encountered wrong path issue before . It gives me another error message than this.
java.io.IOException: error=2, No such file or directory

Hi sanidu_lakmal

I don't see much options other than the provided config which would cause this issue. Can you share what exact JRS version are you using? Is it 8.2 or 8.0.4? Do you have all the hot fixes applied specific to the version you are using? Can you try with the latest version with all the hot fixes applied? That will make sure all the configuration are applied correctly. We don't see any other reason behind this error.

[sanidu_lakmal]

Hi jmand !

It is 8.0.2 on my remote Environment

but it is working on my local which has the version 8.0.0
