HI,
For a client I am using the following configuration:
1-An OpenDS server version 2.2
2-An OpenLDAP client (the Novel libraries)

Both are very easy to use.

There is a need to query the LDAP server for information such as password expiration time, number of failed logins etc. This information is readily available by using a command line interface which is provided by OpenDS : https://docs.opends.org/wiki/Diff.jsp?page=HowToManageUserAccounts&r1=20...

For instance to get the failure time one would invoke:

<code>
manage-account get-authentication-failures-times \
--targetDN "uid=kvaughan,ou=People,dc=example,dc=com" \
--hostname localhost --port 1389 \
--bindDN "cn=Directory Manager" --bindPassword password

The blog post compares the performance and memory footprint of Wicket vs JSF+Seam by implementing one of seam examples in Wicket. 

Bottom line: Wicket is a clear winner.

The author has other implementations, including for tapestry, grails and wicket with groovy / scala: http://code.google.com/p/perfbench/ (anyone up to writing a django implementation?)

Regarding Scala vs. Java, here's the same wicket page in Scala and Java:

I need something that creates symbolic link aka shortcut on Windows.

Code below creates symbolic link on Linux

<code>

Runtime.getRuntime().exec("ln -s <target> <link>");

</code>

Some windows installations can contain linkd.exe/shortcut.exe/xxxlink.exe but some don't.

I need something that will surely work on all. may be JNI and C/C++.

Good news for those of you who love working with Notepad++ and work with Subversion!

No need to switch to Explorer for simple SVN actions anymore - there is a Subversion plugin for Notepad++ that should work under Windows XP, Vista, and 7. Both 32 bit and 64 bit operating systems are supported.
