PoolableSQLConnectionFactory$1 on new install on tomcat 8

[rpoyner]

Using: SmartClient_v110p_2017-05-15_PowerEdition

I'm doing my first install on a tomcat server. When I load the page the outline of the gui appears but when it tries to initially populate the data I get a warning box with:

com/isomorphic/sql/PoolableSQLConnectionFactory$1

I'm still working on getting logging configured so I can see the isomorphic server logs, but maybe this is the result of some common newb mistake?

Thanks

No way to tell - keep going on getting the logging set up as that's the starting point of all troubleshooting.

Figured out the log. First thing I notice is that the log timestamps are UTC, not local time. I wonder if that will cause problems talking to MySQL or Oracle.

Here is a portion of the log that seems interesting:

[rpoyner]

Solved it. The critical log entry is:

java.lang.NoClassDefFoundError: org/apache/commons/dbcp/PoolableConnection

Those in the know might deduce that commons-dbc-nnn.jar is missing. For me the answer was to grep the jar files in the SDK.

cd smartclientSDK/WEB-INF/lib/
for n in `ls *.jar`;do jar -tvf "$n" | grep -Hsi PoolableConnection && echo $n ;done

Which output the name of the maching jar file:

commons-dbcp-1.3.jar
