Bug #: 51558
Summary: Tomcat Embedded: using tomcat.addWebapp always
overrides programmatic context-settings with default
values for the context at start of tomcat server
Product: Tomcat 7
Version: 7.0.16
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
AssignedTo: [email protected]
ReportedBy: [email protected]
Classification: Unclassified
when i deploy an webapp with a tomcat server, i use the Function
"tomcat.addWebapp". I looked into the code of this function and it makes the
following call:
ctx.addLifecycleListener(new DefaultWebXmlListener());
When i start tomcat, this DefaultWebXmlListener is activated automatically, and
always does the following code, so the manager i set for my context gets
overriden with this code:
public static void initWebappDefaults(Context ctx) {
...
// Sessions
ctx.setManager( new StandardManager());
ctx.setSessionTimeout(30);
...
}
so when i set a StandardManager programatically, it gets overriden by this
code. The workaround i used, is to unregister the DefaultWebXmlListener, and
than add my own context.xml specific settings, like a custom manager for
deactivating session persistance:
Context warContext = tomcat.addWebapp(warContextPath, warLocation);
LifecycleListener[] lclisteners = warContext.findLifecycleListeners();
LifecycleListener defaultWebXMLListener = null;
for (int i=0; i < lclisteners.length; i++){
if (lclisteners[i] instanceof DefaultWebXmlListener){
defaultWebXMLListener = lclisteners[i];
}
}
warContext.removeLifecycleListener(defaultWebXMLListener);
...
StandardManager manager = new StandardManager();
manager.setPathname(null); // disable session persistance:
//manager.setPathname("SESSIONS.ser");
warContext.setCookies(true);
warContext.setCrossContext(true);
warContext.setManager(manager);
i think its a bug that using the "tomcat.addWebapp" method makes it impossible
to set context.xml specific settings programmatically, because they always get
overriden by default values at the tomcat start.
