RE: How to use catalina classloader
The manager servlet implements CatalinaServlet (so gets initialized with setWrapper method). I have written a similar custom servlet, but it seems to be not calling setWrapper since it dosent load using the Catalina classloader. The documentation suggests to be put the classes in server/classes, but it makes automated builds harder. Besides tomcat manager dosent seem to have its classes in server/classes. Any help is appreciated.

Re: How to use catalina classloader
thats because the manager webapp accesses classes from $TOMCAT_HOME/server/webapps/manager/WEB-INF/lib/catalina-manager.jar if you place the classes in $TOMCAT_HOME/server/webapps/manager/WEB-INF/classes the manager webapp will be able to access those classes M- This e-mail communication and any attachments may contain confidential and privileged information for the use of the designated recipients named above.

It's ContainerServlet, not CatalinaServlet. A higher degreee of accuracy in your mailings will get you answers faster. Besides tomcat manager dosent seem to have its classes in server/classes.

Subject: RE: How to use catalina classloader
Wondering if the code loads with Catalina
classloader based on package structure ?
Looks to me like either that or the privileged flag should work. Here's
the relevant code snippets from StandardWrapper.java:
// Special case class loader for a container provided
servlet
if (isContainerProvidedServlet(actualClass)
! ((Context)getParent()).getPrivileged() ) {
// If it is a priviledged context - using its own
// class loader will work, since it's a child of the
container
// loader
classLoader = this.getClass().getClassLoader();
}
// Special handling for ContainerServlet instances
if ((servlet instanceof ContainerServlet)
(isContainerProvidedServlet(actualClass) ||
((Context)getParent()).getPrivileged() )) {
((ContainerServlet) servlet).setWrapper(this);
}
/**
* Return codetrue/code if the specified class name represents a
* container provided servlet class that should be loaded by the
* server class loader.
*
* @param classname Name of the class to be checked
*/
private boolean isContainerProvidedServlet(String classname) {
if (classname.startsWith(org.apache.catalina.)) {
return (true);
}
try {
Class clazz =
this.getClass().getClassLoader().loadClass(classname);
return (ContainerServlet.class.isAssignableFrom(clazz));
} catch (Throwable t) {
return (false);
}
}
Not sure why the privileged flag by itself is insufficient. Perhaps the
since it's a child of the container loader comment isn't completely
accurate, or something isn't being inherited properly.
