Issue/Introduction

After CU2 patch installation, observed several error messages (java.io.FileNotFoundException) in UI and Manager log files.

Cause

Reference to tools.jar is a historical reference that would not cause a problem but had not been removed.

Changes in Tomcat configuration for jarscanner relate to the upgrade to Tomcat 9.0.45 in CU2

There is no functional impact to the errors

Resolution

1.) Stop all the SOI Services

2.) For UI, 

        a.) Go to <SOI_HOME>\SamUI\conf\ and edit context.xml

        b.) Add <JarScanner scanManifest="false"/> entry within <Context> tag and save it.

        c.) Go to <SOI_HOME>\jsw\conf\ and edit soi-user-interface.conf 

        d.) Comment(by adding #) or remove below entry

                wrapper.java.classpath.2=%JAVA_HOME%/lib/tools.jar

3.) For Manager, 

        a.) Go to <SOI_HOME>\tomcat\conf\context.xml and edit context.xml

        b.) Add <JarScanner scanManifest="false"/> entry within <Context> tag and save it.     

        c.) Go to <SOI_HOME>\jsw\conf\ and edit soi-manager.conf

        d.) Comment(by adding #) or remove below entry 

                wrapper.java.classpath.2=%JAVA_HOME%/lib/tools.jar

4.) Now Start all the SOI Services in the recommended order.

Additional Information

This is still necessary after applying CU3
