no way to specify external classpath with updateDomain or scripts using online wlst

[rjnkmr]

Most of the scripts (tool) use shared.sh and in this script the WLST_EXT_CLASSPATH is set to a fixed value (and is not extended).
WLST_EXT_CLASSPATH="${WLSDEPLOY_HOME}/lib/weblogic-deploy-core.jar"; export WLST_EXT_CLASSPATH

So there is not way to set classpath before calling a tool, for example updateDomain.sh.

In case of pure wlst using "${ORACLE_HOME}/oracle_common/common/bin/wlst.sh", I have used WLST_EXT_CLASSPATH for that purpose.

I have noticed this in case of updating "Custom security providers", see: https://oracle.github.io/weblogic-deploy-tooling/samples/securityproviders-model/

For example updating this configuration

SecurityConfiguration:
    Realm:
      myrealm:
        RoleMapper:
          XACMLRoleMapper:
            XACMLRoleMapper:
          myAppRoleMapper:
            "xyz.myAppRoleMapper":
              URL: 'someUrl'
              User: 'someUser'
              PasswordEncrypted: 'somePwd'
              CacheExpiresInSeconds: 3605

produces this error

I am using WDT version 2.1.0 with weblogic 14.1.1.0

The probable solution I see is, by propagating (extending) the set value of WLST_EXT_CLASSPATH in shared.sh script:
WLST_EXT_CLASSPATH="${WLST_EXT_CLASSPATH}:${WLSDEPLOY_HOME}/lib/weblogic-deploy-core.jar"; export WLST_EXT_CLASSPATH
