I've had a lot of issues with JasperServer. A **LOT**. Even on freshly installed operating systems, things often just randomly fail with NullPointerExceptions and memory leaks being reported in catalina.log. No idea what's going on inside of the web application, but many issues are simply beyond my capability. How much for one-off assistance if we provide you with SSH access? Is it a per-hour amount or is it a per-job amount?

Try this. echo $RANDOM The result should be 5. If it's a different error, there's a problem with your setup or report, not with JasperServer. /END SARCASM

Wow, someone on the forums had to solve the issue themselves without any help from staff. Big surprise there.

Really? No assistance with this?

14 years old an not even a response from staff.

lucianc, that makes sense and is the typical reason software provides unique identifiers to customers on errors. However, in this case I am the system administrator, and as per my original post, the only thing that appears in the error log is a message to contact the system administrator.

I see frequent references in the logs to error UIDs. 2020-03-02 09:41:59,093 ERROR SecureExceptionHandlerImpl,pool-5-thread-2:116 - There was an error on the server. Try again or contact site administrators. (Error UID: c4c3f8d2-6fab-4e01-abdb-93aecba1d563)[/code]I have searched the entire database: psql -tA -U postgres -d jasperserver -c "select 'select ' || quote_literal(column_name) || ', count(*) from ' || table_schema || '.' || table_name || ' where ' || column_name || ' ilike XXX' from information_schema.columns where data_type in ('text', 'character varying')" | sed "s/XXX/'%c4c3f8d2-6fab-4e01-abdb-93aecba1d563%' union all/g" | paste -s - -d ' ' | sed 's/union all$//g' | psql -U postgres -d jasperserver -tA[/code] I have also searched the directory structure: grep -rHniF c4c3f8d2-6fab-4e01-abdb-93aecba1d563 /opt/jasperreports-server-cp-7.2.0[/code]There are no references to this error ANYWHERE except the original message posted above. So my question is this: Does the error UID even have a purpose, and if so, what is it?

Like most other issues on the JasperSoft website, this issue is nearing ***SIX (6) YEARS** old and not resolved. 28-Feb-2020 12:17:47.108 SEVERE [localhost-startStop-3] org.apache.catalina.loader.WebappClassLoaderBase.checkThreadLocalMapForLeaks The web application [jasperserver] created a ThreadLocal with key of type [com.sun.xml.bind.v2.runtime.Coordinator$1] (value [com.sun.xml.bind.v2.runtime.Coordinator$1@979c98a]) and a value of type [com.sun.xml.bind.v2.runtime.Coordinator[]] (value [[Lcom.sun.xml.bind.v2.runtime.Coordinator;@6d90fbfa]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak. If I had the choice, I would NEVER use Jasper Server again. I would rather use groff, xslt or html2pdf, one of the numerous dedicated PDF libraries, or even a "backyard" solution written by a non-English speaking hermit with zero support.

Year 2020. Still present. Garbage software.

Our installation (year 2020, JasperServer 7.2) produces hundereds of memory leaks per day. 28-Feb-2020 12:17:47.108 SEVERE [localhost-startStop-3] org.apache.catalina.loader.WebappClassLoaderBase.checkThreadLocalMapForLeaks The web application [jasperserver] created a ThreadLocal with key of type [com.sun.xml.bind.v2.runtime.Coordinator$1] (value [com.sun.xml.bind.v2.runtime.Coordinator$1@979c98a]) and a value of type [com.sun.xml.bind.v2.runtime.Coordinator[]] (value [[Lcom.sun.xml.bind.v2.runtime.Coordinator;@6d90fbfa]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak.

I have a very similar issue, which is presenting when the firewall is completely turned off. I've tested the database connection via the command line with the same settings and it works properly.

Did you find a solution to this??

I've had a number of very similar issue with the "Context is read only" error message. Very frustrating.
