Re: [eclipse-clp-users] Problem: OutOfProcessEclipse and Java

Hello,

thank you for your answer but setting the eclipse prolog path is not a 
solution and made no difference. When I set a wrong path I got an error 
message that it can't find eclipse prolog and when I set the right path 
I got the old error message I told you in my last e-mail :( I used the 
setEclipseDir method. It seems that it is a eclipse prolog bug :(

Greetings!

Martin
