Fitnesse – Slim : Could not invoke constructor for : Java Solution

I was trying to install fitnesse and get some basic fixtures(Decision Table) going. I was faced with  ”Could not invoke constructor for”.  I tried a couple of solutions like,

1. Setting the !Path “Location of the .class file”.  I got the location of the .class file wrong. I pointed it to actual directory where .class file was, even though it was in a Java Package.

So the solution was,

!Path “Point to bin directory (Simple Java Project ) or target directory (Maven Project)”

and then create a Import table which specifies the package of the Fixture class. For example:

|import |
|com.om.example.dvr.fixtures|

This will make sure that Fitnesse can find your fixtures. I’m currently using this tutorial, which is turning out to be a wonderful Fitnesse-Slim resource.

I’m going to show my fixture properties. Might be helpful , If you are facing this error.

 

!contents -R2 -g -p -f -h
!define TEST_SYSTEM {slim}

!path C:\Users\ddd\JavaWorkspace\fitnesse-tutorials\my-project\bin
|import |
|com.om.example.dvr.fixtures|

!define COLLAPSE_SETUP {true}
!define COLLAPSE_TEARDOWN {true}

sqlplus: error while loading shared libraries: libsqlplus.so wrong ELF class

sqlplus: error while loading shared libraries: libsqlplus.so wrong ELF class 

This error happens If you are working on a 64 bit operating system and pointing to a 32 bit library.

So this is how your environment variables should look like.

PATH=$PATH:$HOME/bin
ORACLE_HOME=/x/home/oracle/product/11.2.0.1
PATH=$ORACLE_HOME/bin:$PATH
PATH=$ORACLE_HOME/lib64:$PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib64
export ORACLE_HOME
export LD_LIBRARY_PATH
export PATH 

This will fix the issue.
