SLF4J: and java.lang.ClassNotFoundException: errors found on SoapUI-x32-5.2.1

Hello All: I am getting SLF4J and ClassNotFoundException errors while running test using testrunner.bat of SoapUI 5.2.1 (x-32 version). Could you please let me know where is the problem ?     OS ...
plugins
testrunner.bat

    Finally, the problem was solved !

     

    The other problem ties to the default plugins installed under "C:\Users\<user name>.soapuios\plugin".

     

    For SoapUI 5.2.1, there are 4 default plugins installed under this directory:

    1. readyapi-swaggerhub-plugin-1.0.jar
    2. ready-mqtt-plugin-dist.jar
    3. ready-uxm-plugin-1.0.1-dist.jar
    4. soapui-swagger-plugin-2.2-dist.jar

    Renamed the original folder 'plugins' to 'plugins_NOTinUse' (or something else), so that default plugins could be forced hidden during runtime. The problem then disappeared.

     

    Kudos for Rao for all the hints he gave me to resolve the issue under this thread.

    Now, I am able to enjoy ZERO error testing :smileyhappy:

     

    Suggestion, packaging of SoapUI can be modified to avoid installing default plugins.

Thank you for your patience. It is absolutely strange. Can you try starting soapui from command prompt (open cmd prompt, go to soapui_home/bin/soapui.bat) and what happens in the console?

Hello Rao:
Thanks again for your debugging direction.
I started soapui.bat from Windows command shell and captured the logs (two files attached below). The SoapUI application started as expected. But the captured logs have errors.

    It is really strange behaviour, no one really mentioned of this issue. Do you want to try on another /a collegue machine if any/possible?
    Otherwise, remove the plugins (you can see the location from the above log) and try.
    You can also download slf4j jar from internet (that is only case if that does not exists, but you say that is available).

    Hello Rao:

    I know you would respond to my posting, thank you.

     

    This is my 3rd machine having the same error message.

    Note that, I am setting up a lab with 4 new HP Z440 desktop machines running Windows 7 to run some web service testing for a project, I have another machine left which I'll try on Monday. I am pretty sure, the outcome would be the same :-(

     

    Yes, SLF4J is already existed under the SoapUI install directory.

     

    BTW, could you please comment about the other execeptions (Java exceptions).

     

    Regards.

    Hello Rao (and other friends following this thread):

    After a hint from you (thanks again :smileyhappy: ), I started investigating what SLF4J tells about this error.

     

    I found a solution they suggested in their webpage (SLF4J.org) as below:

    Failed to load class org.slf4j.impl.StaticLoggerBinder

This error is reported when the org.slf4j.impl.StaticLoggerBinder class could not be loaded into memory. This happens when no appropriate SLF4J binding could be found on the class path. Placing one (and only one) of slf4j-nop.jar, slf4j-simple.jar, slf4j-log4j12.jar, slf4j-jdk14.jar or logback-classic.jar on the class path should solve the problem.

    I then downloaded slf4j and extracted the file slf4j-nop-x.x.xx from the package and put under the SoapUI lib folder (where slf4j-api-x.x.xx already pre-existed. This new file, slf4j-nop-x.x.xx eliminated the SLF4J loading error completely.

     

    Now, I need your help to resolve the other error: "java.lang.ClassNotFoundException: com.eviware.soapui.plugins.auto.factories.AutoDiscoveryMethodFactory".

    Note that, upon searching, I found a thread related to the same problem here: AutoDiscoveryMethodFactory ClassNotFoundException....

     

    Thanks.

    What if these plugins are required ? This solution doesn't works in that case.

    DO you want to open a new topic instead of reviving a closed one? By the way, which plugin you wanted to used ? what did you try and what is the error do you see?
    I at least use swagger plugin and it worked.

    Hi nmrao,

     

    I am also trying to use swagger plugin but for me the solution suggested doesn't works. Swagger plugin doesn't gets loaded.
