A

You are getting the following SoapUI error, because the SLF4J implementation JAR file is not included in the installation:

C:\fyicenter>\fyicenter\SoapUI\bin\soapui.bat
...
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
...

You can download and install SLF4J implementation JAR to fix the error.

1. Go to https://www.slf4j.org/download.html site.

2. Download slf4j-1.7.25.zip and unzip it.

3. Copy the following two JAR files from the slf4j-1.7.25.zip to SoapUI installation:

c:\copy \fyicenter\slf4j-1.7.25\slf4j-api-1.7.25.jar \fyicenter\SoapUI\lib
c:\copy \fyicenter\slf4j-1.7.25\slf4j-simple-1.7.25.jar \fyicenter\SoapUI\lib

4. Delete the old slf4j-api-1.6.1.jar from SoapUI installation:

c:\del \fyicenter\SoapUI\lib\slf4j-api-1.6.1.jar

This will resolve the "SLF4J: Failed to load class" error.
