SchemaSpy DB2 Connection Failure - db2

Question

I tried to analyze a DB2 database with SchemaSpy, but got a warning 'Connection Failure'. I tried this way:
java -jar schemaspy-6.0.0.jar -configFile schemaspy.properties --logging.pattern.console="%d{HH:mm:ss.SSS} %clr(%-5level) - %msg%n" --logging.level.org.schemaspy=TRACE
(found the logging part on https://github.com/schemaspy/schemaspy/issues/250)
The .properties file looks like this:
schemaspy.t=db2
schemaspy.dp=C:\tmp\db2jcc.jar
schemaspy.host=**host**
schemaspy.port=50000
schemaspy.db=**db**
schemaspy.u=**user**
schemaspy.p=**password**
schemaspy.o=D:\**\schemaspy-output\
schemaspy.s=**schema**
The error I got was:
14:24:20.297 DEBUG - Unable to find driverClass COM.ibm.db2.jdbc.app.DB2Driver'
14:24:20.308 WARN - Connection Failure

I guess, the error comes from the wrong class path? But how can I fix this? I tried to change the line in db2.properties
driver=COM.ibm.db2.jdbc.app.DB2Driver
to
driver=COM.ibm.db2.jcc.DB2Driver
, because I extracted this class path from the driver's .jar flie, but it did not help.

Answer 1

this worked for me using db2jcc.jar
# type of database. Run with -dbhelp for details
schemaspy.t=db2
# optional path to alternative jdbc drivers.
schemaspy.dp=/lib/db2jcc.jar
# database properties: host, port number, name user, password
schemaspy.host=xxxxxx
schemaspy.port=xxxxx
schemaspy.db=xxx
schemaspy.u=xx
schemaspy.p=xx
# output dir to save generated files
schemaspy.o=/output
# db scheme for which generate diagrams
schemaspy.s=xxxx
driver=com.ibm.db2.jcc.DB2Driver
connectionSpec=jdbc:db2://xxx.xx.x.xxx:[PORT]/[DBNAME]
schemaspy.cat=%
The command used:
java -jar schemaspy-6.1.0.jar -configFile db2.properties --logging.pattern.console="%d{HH:mm:ss.SSS} %clr(%-5level) - %msg%n" --logging.level.org.schemaspy=TRACE
