Is there a difference between your versions of Java? > Please, has anyone got imageop scale and resize working on 2.1.12? No. I looked yesterday at Cocoon running locally using the SVN branch 2.1.13-dev The block samples show the same as what you described above. The cocoon log file does show the errors, but doesn't mean much to me. This was with Java 8. The only thing that i can suggest is to look at the changes that have been made to the code in 2.2 and compare with 2.1 branch. http://svn.apache.org/viewvc/cocoon/branches/BRANCH_2_1_X/src/blocks/imageop/ http://svn.apache.org/viewvc/cocoon/trunk/blocks/cocoon-imageop/ Perhaps when the last changes were made, then there was a slight difference, and perhaps no-one tested after that. Those last changes seem to be https://issues.apache.org/jira/browse/COCOON-2169 https://issues.apache.org/jira/browse/COCOON-2177 -David > Thanks > > Peter > > > > On 17/09/2014 07:11, Miguel wrote: > >I've done some test and modulo in cocoon 2.2 project works fine.
