EMC Documentum includes Java Method Server (JMS), a customized version of JBoss to execute Content Server Java methods. One Java Method Server is installed with each Content Server installation. You can use Documentum Administrator to modify existing Java Method Servers, but you cannot add new Java Method Servers from the Documentum Administrator interface. To add a Java Method Server, you have to run the Content Server Configuration Program. For more information about installing multiple Content Servers, Java Method Servers, and the supported JMS failover configurations, refer to the Content Server Enterprise Edition Installation Guide.
EMC Documentum provides a servlet called DO_METHOD to execute Documentum Server methods. The compiled servlet code is found in the mthdservlet.jar file located on the same host as Content Server. The file contains the IDmMethod class. Java Method Server runs as an independent process. The process can be stopped or started without recycling the Content Server. On Windows platforms, the Java Method Server can be run as a Windows service or as a process.
The method server itself is a Java-based web application. Each time a method is invoked, the Content Server makes an HTTP request passing the name of the Java class which implements the method along with any specified arguments to a servlet which knows how to execute the specified method.
The Java method server can also be used to execute Java methods that are not associated with a method object. Use an HTTP_POST administration method to send the request to the Java method server. For details about the administration method, refer to the Content Server DQL Reference Manual.
