Activiti is distributed under the Apache V2 license. The distribution contains most of the sources as jar files. Activiti runs on a JDK higher than or equal to version 7. There are installation instructions on that page as well.
To verify that your installation was successful, run java -version on the command line. That should print the installed version of your JDK. Activiti development can be done with the IDE of your choice.
Download the eclipse distribution of your choice from the Eclipse download page. Unzip the downloaded file and then you should be able to start it with the eclipse file in the directory eclipse. Further in this user guide, there is a section on installing our eclipse designer plugin. Every self-respecting developer should have read How to ask questions the smart way. All classes that have. However, if the user guide mentions those classes as configuration values, they are supported and can be considered stable.
In the jar file, all classes in packages that have. No stability guarantees are given on classes or interfaces that are in implementation classes. After downloading the Activiti UI WAR file from the Activiti website , follow these steps to get the demo setup running with default settings. But we test on Tomcat primarily. Login with admin and password test. The Activiti UI application uses an in-memory H2 database by default, if you want to use another database configuration please read the longer version.
The way to do this depends on your operating system. By default the UI application runs with an in-memory database. The process engine user console. Use this tool to start new processes, assign tasks, view and claim tasks, etc.
Note that the Activiti UI app demo setup is a way of showing the capabilities and functionality of Activiti as easily and as fast as possible. This does however, not mean that it is the only way of using Activiti. Or you could very well choose to run Activiti as a typical, standalone BPM server. If it is possible in Java, it is possible with Activiti!
As said in the one minute demo setup, the Activiti UI app runs an in-memory H2 database by default. To run the Activiti UI app with a standalone H2 or another database the activiti-app.
To include the Activiti jar and its dependent libraries, we advise using Maven or Ivy , as it simplifies dependency management on both our and your side a lot. The Activiti download zip contains a folder libs which contain all the Activiti jars and the source jars. The dependencies are not shipped this way. The required dependencies of the Activiti engine are generated using mvn dependency:tree :. Note: the mail jars are only needed if you are using the mail service task. All the dependencies can easily be downloaded using mvn dependency:copy-dependencies on a module of the Activiti source code.
Playing around with the Activiti UI web application is a good way to get familiar with the Activiti concepts and functionality. However, the main purpose of Activiti is of course to enable powerful BPM and workflow capabilities in your own application. The following chapters will help you to get familiar with how to use Activiti programmatically in your environment:.
The chapter on configuration will teach you how to set up Activiti and how to obtain an instance of the ProcessEngine class which is your central access point to all the engine functionality of Activiti.
These services offer the Activiti engine functionality in a convenient yet powerful way and can be used in any Java environment. Then continue on to the BPMN 2. The Activiti process engine is configured through an XML file called activiti. The easiest way to obtain a ProcessEngine , is to use the org. ProcessEngines class:. This will look for an activiti.
The following snippet shows an example configuration. The following sections will give a detailed overview of the configuration properties. Note that the configuration XML is in fact a Spring configuration.
This does not mean that Activiti can only be used in a Spring environment! We are simply leveraging the parsing and dependency injection capabilities of Spring internally for building up the engine.
The ProcessEngineConfiguration object can also be created programmatically using the configuration file. It is also possible to use a different bean id e.
It is also possible not to use a configuration file, and create a configuration based on defaults see the different supported classes for more information.
All these ProcessEngineConfiguration. After calling the buildProcessEngine operation, a ProcessEngine is created:. The activiti. This bean is then used to construct the ProcessEngine. There are multiple classes available that can be used to define the processEngineConfiguration.
These classes represent different environments, and set defaults accordingly. The following classes are currently available more will follow in future releases :. StandaloneProcessEngineConfiguration : the process engine is used in a standalone way. Activiti will take care of the transactions. By default, the database will only be checked when the engine boots and an exception is thrown if there is no Activiti schema or the schema version is incorrect.
An H2 in-memory database is used by default. The database will be created and dropped when the engine boots and shuts down. When using this, probably no additional configuration is needed except when using for example the job executor or mail capabilities. SpringProcessEngineConfiguration : To be used when the process engine is used in a Spring environment. See the Spring integration section for more information. There are two ways to configure the database that the Activiti engine will use.
The first option is to define the JDBC properties of the database:. The data source that is constructed based on the provided JDBC properties will have the default MyBatis connection pool settings. The following attributes can optionally be set to tweak that connection pool taken from the MyBatis documentation :.
Default is Default is 20 seconds. Our benchmarks have shown that the MyBatis connection pool is not the most efficient or resilient when dealing with a lot of concurrent requests.
As such, it is advised to us a javax. Note that Activiti does not ship with a library that allows to define such a data source. So you have to make sure that the libraries are on your classpath.
The following properties can be set, regardless of whether you are using the JDBC or data source approach:. Should only be specified in case automatic detection fails. See the supported databases section for an overview of which types are supported. By default, the database configuration for Activiti is contained within the db. By using JNDI Java Naming and Directory Interface to obtain the database connection, the connection is fully managed by the Servlet Container and the configuration can be managed outside the war deployment.
This also allows more control over the connection parameters than what is provided by the db. Configuration of the JNDI datasource will differ depending on what servlet container application you are using. The instructions below will work for Tomcat, but for other container applications, please refer to the documentation for your container app. The default context is copied from the Activiti war file when the application is first deployed, so if it already exists, you will need to replace it.
Default is \”true\”. Add an Activiti configuration file activiti. However, often only database administrators can execute DDL statements on a database. On a production system, this is also the wisest of choices. The scripts are also in the engine jar activiti-engine-x. The SQL files are of the form. Where db is any of the supported databases and type is. These tables are optional and should be used when using the default identity management as shipped with the engine.
Optional: not needed when history level is set to none. Note that this will also disable some features such as commenting on tasks which store the data in the history database. When using the DDL file approach, both a regular version and a special file with mysql55 in it are available this applies on anything lower than 5.
This latter file will have column types with no millisecond precision in it.

Honorary Professor at UCT. His primary research interests are C-type lectin receptors and their role in homeostasis and immunity, with a particular focus on antifungal immunity. His research interests revolve around investigating immune regulation and dysregulation in the context of HIV infection or exposure.
He focuses on Immune ontogeny in HIV exposed infants, placental investigations and pre-term birth, and epithelial immunity in the foreskin.
Her Research Unit is involved with clinical research, epidemiology and operational research, and is a treatment site for HIV infected adults and children. Her research interests include HIV vaccine research, microbicide research and other biomedical and behavioural interventions, and she is an investigator in testing two HIV vaccine regimens in late stage clinical development.
He has been an author on over manuscripts in the field of infectious diseases and has an extensive track record in infectious diseases research and practice covering clinical, laboratory and epidemiological aspects. He is an HIV and TB immunologist focused on studying the immune response to these pathogens in affected tissues, and how this relates to what can be observed from the blood.
The research goal is to improve understanding of the immunopathology of TB and HIV, using this information to aid in developing novel therapeutic approaches and diagnostic biomarkers.
His research has centered on understanding the mechanisms by which the human immune system recognises the Mycobacterium tuberculosis M. His work has a strong translational component, asking if both classically and non-classically restricted T cells are associated with infection with M. The translational significance of this research is centred on informing the development of novel vaccines and diagnostics for childhood TB. Her current research focuses on HIV broadly neutralising antibodies and their interplay with the evolving virus.
Recent studies published in PloS Pathogens, Nature and Nature Medicine have highlighted the role of viral escape in creating new epitopes and immunotypes, thereby driving the development of neutralisation breadth, with implications for HIV vaccine design. Research interest in tuberculosis and in developing and testing point of care diagnostics suitable for the developing world.
More specifically, the reconstitution of the immune response during antiretroviral treatment, in order to identify correlates of protection including immune mechanisms that lead to reduced susceptibility to TB , and pathogenesis such as the Tuberculosis-Associated Immune Reconstitution Inflammatory Syndrome, TB-IRIS ; the biosignature of the TB infection spectrum, from latent infection to active disease; preventing TB infection in HIV infected people more effectively; and the pathogenesis of tuberculous meningitis and pericarditis.
