| destroy | | public void destroy()(Code) | | Finalize this servlet.
|
| displaySize | | protected void displaySize(StringBuffer buf, int filesize)(Code) | | Display the size of a file.

existing content in oldRevisionContent (if present). This code does
not support simultaneous partial updates to the same resource.
|
| getETag | | protected String getETag(ResourceInfo resourceInfo)(Code) | | Get the ETag associated with a file.
Parameters:
resourceInfo - File object
Parameters:
strong - True if we want a strong ETag, in which case a checksumof the file has to be calculated |
| getRelativePath | | protected String getRelativePath(HttpServletRequest request)(Code) | | Return the relative path associated with this servlet.
Parameters:
request - The servlet request we are processing |
| getResources | | protected DirContext getResources()(Code) | | Get resources. This method will try to retrieve the resources through

disabled). It will return null.
A JNDI DirContext, or null. |
| normalize | | protected String normalize(String path)(Code) | | Return a context-relative path, beginning with a "/", that represents
the canonical version of the specified path after ".." and "." elements

boundaries of the current context (i.e. too many ".." path elements

Parameters:
path - Path to be normalized |
