External library use within the EP6 framework

hi all,

we are trying to make use of an external java lib (.jar)

this lib is quite big, like 6mb ⚠️

We tried to set a modified classpath in the go_loop.bat start file. it is supposed to point the folder where we have our .jar file somewhere on the server (equivalent to configuring the portal through the use of the j2ee server config tool)

the error we have is quite interesting : the dispatcher fails to start ! (and therefore the portal remains silent)

What we did in order to get convinced that our jar is for nothing in this problem, is that we placed it as a reference in our iview code : and it works...

has anyone an idea about this ?

that we be a pity to be forced to have ext ref in iview code as some jar are too big for this.

thanks a lot
