[copied from post to Help Forum]
I successfully installed combean with swimp in NetBeans 7.1.1 and solved a simple LP. However, to get my code to run I had to add two jar files to the library that were not documented in the instructions.
I needed qsopt.jar which I downloaded from http://www.tsp.gatech.edu/~wcook/qsopt/downloads/downloads.htm.
I also needed commons-collections-3.2.1.jar which I downloaded from http://commons.apache.org/collections/download_collections.cgi.
The problem is that the license for qsopt.jar is not as generous as the licenses for combean and swimp. Is there an alternative source for the necessary class files with a more open license?
If I omit the qsopt.jar file from the library, I get an error message "java.lang.NoClassDefFoundError: qs/QSException". A websearch led me to the gatech site for qsopt.jar. Thanks, Peter
