Re: [daemon] JSVC re-exec requires execution with an absolute or relative path

Hi: UPDATE: The UNIX error message is referring to the absolute path of the jsvc executable. When I invoked the executable with its absolute path it worked. I assume it's the same problem on Mac OS X. /usr/local/bin/jsvc -jvm server -debug -home /usr/lib/jvm/java-6-openjdk -cp /usr/local/bin/

Hi. Thanks Luc for your help. I modified my code as you recommend (it is given below), but it doesn't work either. The error message (at running) is : Exception in thread "main" org.apache.commons.math3.exception.MathUnsupportedOperationException: contrainte [...] It is about a contraint

If you are implementing on Linux classpath version mismatches can be overcome by executing version-specific maven-jsvc-plugin in pom.xml Maven-Jsvc-Plugin grab the source here https://github.com/jeroenr/Maven-Jsvc-Plugin Martin Gainty _
