The primary means of integrating with MantisBT is with the SOAP API , bundled with MantisBT. The SOAP API is accessible at http://server.com/mantis/api/soap/mantisconnect.php. For ease of integration of the Java clients, SOAP stubs are maintained and deployed in the Maven central repository. To include them in your project, use the following coordinates: <dependency> <groupId>biz.futureware.mantis</groupId> <artifactId>mantis-axis-soap-client</artifactId> <version>1.2.6</version> </dependency> Alternatively, download the latest available version from http://search.maven.org/#search|gav|1|g%3A%22biz.futureware.mantis%22%20AND%20a%3A%22mantis-axis-soap-client%22. If you would like to use Axis in an OSGi environment, it is recommended that you use a ready-made bundle, such as the Axis bundle available from Eclipse Orbit The SOAP API signature will change between minor releases, typically to add new functionality or to extend existing features. Some of these changes might require a refresh of the client libraries generated, for instance Apache Axis 1 SOAP stubs must be regenerated if a complex type receives a new property. Such changes will be announced before the release of the new MantisBT version on the mantisbt-soap-dev mailing list . Typically there will be two weeks time to integrate the new SOAP stubs. The primary means of obtaining support is through the mantisbt-soap-dev mailing list.
