OSWorkflow

It does not use a graphical tool for developing workflows, but can be configured by writing a xml file as the main conf file for the workflow process.

Graphical solutions don't provide the flexibility to properly fulfill all requirements in a full-blown application. In this way the programmer can go in and customize the OSWorkflow after his specific needs.

Situations like "loops" and "conditions" that might be represented by a graphical icon in other workflow systems must be "coded" in OSWorkflow.

Compiling from CSV:

To get the latest version of OSWorkflow,it is recommend that the source via CSV is to be downloaded and compiled using the Jakarta Ant build script provided there. Compiling OSWorkflow from source is trivial with the following ant targets:

1. jar (default) - compiles the library osworkflow.jar
2. example-war - compiles and assembles osworkflow-2.8.0-example.war, which is configured to use memory persistence and should deploy without any configuration into most web containers.
3. example-ear - compiled and assembles osworkflow-2.8.0-example.ear, which is a J2EE application that is configured to use osworkflow with the EJB persistence store. Some configuration of data sources is required, as well as a full J2EE application server.
4. client-jar - compiled and assembles designer.jar, which is a Swing GUI workflow designer application that can be used to visually inspect and edit workflows.
