ROOT

Software AG Spring Board
buffer restriction
Integration Server does not support incremental buffering of HTTP responses.
Clients are connecting directly to Tomcat HTTP listeners and use the typical Tomcat buffering methods.
shared jars
All files in ServerClassloader, including common/lib and common/lib/ext.
All files in the org.apache.catalina host bundle classpath graph.
undeployment
Unloading the IS web package removes the WAR application from the container.
You must remove the WAR project from the Software AG_directory /profiles/IS_default/workspace/webapps/ directory path.
server configuration path
Integration Server_directory /web/conf/
Software AG_directory /profiles/IS_default/configuration/tomcat/conf/
port configuration path

Leverages the Integration Server JAAS-based configuration.
tomcat.base path
Integration Server_directory /instances/ instance_name/web/
Software AG_directory /profiles/IS_default/configuration/tomcat
Tomcat filter support
Filtering happens at a late stage, after WmTomcat sends a request to the embedded Tomcat.
Fully supported.
logging
You must copy the commons-logging.properties file to the directory where the package containing your web application that uses the Jakarta commons-logging API is located.
WmAppPlat bridges logs to Log4j and writes them to the sag-osgi.log and wrapper.logs files for your web application container.
Tomcat Manager Application
Included in WmTomcat.
Not included in WmAppPlat. You can install it separately. For more information about installing the Tomcat Manager Application, see Administering Web Applications.
security realm
The Integration Server realm is used.
By default, the org.apache.catalina.
realm.LockoutRealm
is used. You can also add a custom AppPlatformRealm.
working directory
WmTomcat uses the Integration Server_directory
\instances\instance_name\web\work directory as a working directory and Apache Tomcat administers this directory.
Software AG_directory /profiles/IS_default/workspace/work/
