In case of compilation error Resin shows a simple page with the only message:
Server Error
The server is temporarily unavailable due to an internal error. Please
notify the system administrator of this problem.
And all significant information I should seek in the log file.
Is it possible to redirect somehow all error diagnostics to the browser window?
Try setting <development-mode-error-page/> tag to true. In later versions of Resin the value is externalized into resin.properties:dev_mode

With some Uploads in Moodle (3.9) Uploads are not successful, mainly pdf.
The message that comes up is: "An error occured whilst communicating with the server".
not successful requests show
POST /course/dndupload.php undefined
successful requests show
POST /course/dndupload.php HTTP/1.1
When a pdf is reexported with libre office for example the same pdf can be uploaded without problems.
any ideas?
Is the LibreOffice pdf smaller? It could be PHP timing out.
https://docs.moodle.org/311/en/File_upload_size#Modifying_the_php.ini_file
What is the value for max_execution_time ? You can check the PHP values here -
Site administration > Server > PHP info
Also, try switching debug to developer level and see what the error message is.
Site administration > Development > Debugging
Debug messages = Developer
Display debug messages = checked
Although be cautious changing the debug level if its a production site. If you have access to the config.php file then you can specify a user.
// You can specify a comma separated list of user ids that that always see
// debug messages, this overrides the debug flag in $CFG->debug and $CFG->debugdisplay
// for these users only.
// $CFG->debugusers = '2';
Thanks for the response, in the meantime a solution to the problem was found. On the server a measurement against log4j2-vulnerability has been implemented: https://support.f5.com/csp/article/K59329043#proc2. This caused the misbehaviour, the iRule has been removed, now it works again.
All of a sudden we are seeing this random error / exception in our web application.
Failed to load resource: the server responded with a status of 502 (Bad Gateway).
In the Log Stream, we are seeing the following details, with specific error code as 502.3 - Bad Gateway: Forwarder Connection Error (ARR).
Also, sometimes in the browser itself we see "The CGI application did not return a valid set of HTTP errors." getting displayed.
Most of the searches for these error codes refer to "IIS / Proxy Server" configuration. But, we haven't changed any such settings.
The error happens very randomly and not specific to any user action/function. Same functionality works first and on second execution immediately after first one throws this error.
How to figure out what is causing this and how to fix?
I google this question, because the program was normal at the beginning, and the subsequent 502.3 error. After I checked the information on the Internet, I feel that it can only give us an inspiration, and it cannot solve your problem immediately.
So my suggestion is that first you browse post1 and post2 I provided.
Next, proceed to Troubleshoot according to the steps of the official documentation. Specific errors require specific analysis.
The website URL works fine. The link from google maps on the phone works fine. For some reason when you google it in the browser (mobile browser or desktop) you get an Internal Service Error. Google said it was nothing on their end to be done.
Has anyone encountered this or have an idea of what's causing it? The error received is below.
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator and inform them of the time the error occurred, and the actions you performed just before this error.
More information about this error may be available in the server error log.
Apache Server at www.thetechbuyer.com Port 80
As the error suggests, an Internal Server Error is internal to your webapp or web service on your host. It usually means that your program, whatever it is doing, has crashed. This could be because of misconfiguration, or a bug in your code, or something else - without knowing more (possibly a lot more) about your server environment, it is impossible to know what.
Check your server logs - they should have more information.
(It also isn't clear what this has to do with Google+.)
I have migrated an application from WL 8 to WL 10 and set up my managed servers. They indicate that they are running, but when I try to access the site it throws a 404. This is my first time deploying anything on 10 so I could be missing something. Any ideas? Please let me know what additional information could be helpful. edit: I had this working, added a db connection and now it fails.

You got a weblogic.management.DeploymentException and this means that something went wrong in some server even if everything seems OK from the console.
Underlying error is from weblogic.management.configuration.JDBCSystemResourceMBeanImpl so I would review datasource config is appropiate for every target in your environment. Also check that datasource targets are the same as web application targets and JDBC drivers are available at managed servers classpath as well.
Try to log to the WebLogic Admin console and see what is the status of your application.
You can use the 'Testing' tab of your deployment to see the URL that the application has been deployed to. This will assist you in the troubleshooting process.
If you don't see anything here to test there are a few possible reasons, including the following:
The application failed to deploy and/or is not 'Active'
You are using a cluster and no managed servers are running
You have managed servers running but they are not in a 'RUNNING' state
I have problem with WCF on IIS when using diagnostics.
When I call the service I get the following error:
System.Net.WebException: The remote
server returned an error: (500)
Internal Server Error..
If I remove "system.diagnostics" section I dont get error 500 but I get an error
The requested service,
'http://localhost/CustomerServiceSite/Customer.svc'
could not be activated. See the
server's diagnostic trace logs for
more information..
Which obviously needs diagnostics to get fixed.
Any idea why diagnostics doesnt work?
Check event log on web server - http 500 should be logged there. Also check that Account running your AppPool in IIS has access rights to file used for diagnostics.
The diagnostics will write a trace file to disk - maybe the user account WCF/ASP.NET is running under doesn't have permissions to write the file.
If I opened my service in browser (http://localhost/CustomerServiceSite/Customer.svc) I have seen the whole error.
The problem was becouse I used NHibernate and Diagnostics in wrong way. Commenting NHibernate configuration solved my problem.
