Hello Knime Workgroup
I am currently analysing a huge set of data using knime. The data is structured into subsets with identical properties but changing characteristics. I also build a knime (v 1.2.1, developer version) workflow to analyse and visualise one of these subsets and the result was very good. The problem is the number of sets I like to analyse using knime. I do not want to execute the workflow for each of these sets, it is just too much handwork and not applicable for an automated process.
I read below, that it is not possible to iterate a knime workflow as such, unless I use the knime batch process, which I don't want because I have to pre-process and post-process the date I which to send to knime. Storing everything in a flie or database is too much of an afford because of its one time use only (i just did it to test the knime on my data). Therefore, I would like to use the knime functionality as external class library, to invoke knime nodes from within my program. Unfortunately, using the jar-libraries of the eclipse plugins seem not to be working for this.
The following example leads to:
FuzzyClusterNodeModel clusterModel = new FuzzyClusterNodeModel();
leads to the following exception:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/log4j/spi/Filter
The same problem occurs if I try to initialise a factory class.
I would be thankful for any help,
