Managing password updates in Commons-DBCP
Hello Commons-Users, The issue we are having is that we are implementing a policy forcing database account password changes every 90 days. Our DataSource implementation class uses the SharedPoolDataSource (from commons-dbcp) in managing its PooledConnections. Unfortunately, it appears that SharedPoolDataSource maps the user/password info using the user name. If the user's password changes and the old user/password info is already in the Map, a test in the SharedPoolDataSource prevents client apps from getting a connection on the user. Also the Map object is private to SharedPoolDataSource, and simply implementing our own version of SharedPoolDataSource will not work, since there's a ton of package level classes being used. Can anyone provide a straight-forward method to replacing the expired username/password mapping such that a SharedPoolDataSource may recognize/replace the new account password? Thank you for any suggestions. Scott Stevens - Do you Yahoo!? Yahoo! Small Business - Try our new resources site!
[transaction.locking] Modify the behaviour of the ReadWriteUpgradeLockManager
Hi,
In the documentation I find that while an upgrade lock is held, it is possible
for read locks to be obtained, and when the request is made to upgrade to a
write lock, the lock manager prevents additional read locks until the write lock
can be acquired.
I don't understand why when the upgrade lock is granted, it is possible to
obtain read locks ? Is there a reason to keep accepting read locks when you
already know (because there is a upgrade lock on the data) that the data will be
updated soon ?
The behaviour that I want for my lock manager is following. To modify a data,
you must obtain an upgrade lock if there is already read locks on the data and
then to transform the upgrade lock in write lock when all the readers ended.
When the upgrade lock is granted no more read locks could be granted.
Is it possible to implements this behaviour using the
ReadWriteUpgradeLockManager ?
For the moment I implements the transformation of an upgrade lock in a write
lock when all readers finished.
public class LockManager
{
public static ReadWriteUpgradeLockManager mRWULockManager;
public LockManager()
{
mRWULockManager = new ReadWriteUpgradeLockManager
(new PrintWriterLogger(new PrintWriter(System.out), Locking, false)
, mRWULockManager.DEFAULT_TIMEOUT);
}
public static void readDemand(Thread aOwnerId, Interval1D aIntervalToLock)
{
mRWULockManager.readLock(aOwnerId, aIntervalToLock);
}
public static void writeDemand(Thread aOwnerId, Interval1D aIntervalToLock)
{
if(mRWULockManager.tryWriteLock(aOwnerId, aIntervalToLock) == false)
{
upgradeDemand(aIntervalToLock, aOwnerId);
synchronized(aIntervalToLock)
{
try
aIntervalToLock.wait();
writeDemand(aOwnerId, aIntervalToLock);
}
catch (Exception e) {}
}
}
}
/**
* Traitement d'une demande d'un lock Upgrade
* @param aOwnerId Thread Identifiant du demandeur
* @param aIntervalToLock Interval1D Intervalle à verrouiller
*/
public static void upgradeDemand(Interval1D aIntervalToLock, Thread aOwnerId)
{
if(PDOM.TRACE)
System.out.println(LM: Upgrade Demand);
mRWULockManager.tryUpgradeLock(aOwnerId, aIntervalToLock);
}
/**
* Relacher un lock
* @param aIntervalToUnlock Interval1D
* @param aOwnerId Thread
*/
public static void release(Interval1D aIntervalToUnlock, Thread aOwnerId)
{
if(PDOM.TRACE)
System.out.println(LM: Release + aOwnerId + + aIntervalToUnlock);
synchronized(aIntervalToUnlock)
{
mRWULockManager.release(aOwnerId, aIntervalToUnlock);
aIntervalToUnlock.notifyAll();
if(PDOM.TRACE)
System.out.println(LM: Il devrait repartir );
}
}
In this sense the write lock becomes preferred over all other locks when it gets
upgraded from a upgrade lock. Preferred means that if it has to wait and others
wait as well it will be served before all other none preferred locking requests.

commons attribures: Inheritable
Hi all,
I've got a question about the usage of
org.apache.commons.attributes.Inheritable.
I specify an attribute for the method in interface and
I want that attribute to apply to the method in the implementing
class.
For example:
interface ISome {
/** @@Permission(WRITE) */
void someMethod();
}
class CSome {
public void someMethod() {
...
}
}
Now when I call Attributes.getAttribute() for CSome.someMethod I
expect it to return permission attribute specified in ISome. Is it
achievable with org.apache.commons.attributes.Inheritable ?
I made my Permission class (which represents attribute) to extend
Inheritable but it didn't work.
Any help would be appreciated.
Vitali.

Re: [OT] The wisdom of Albert (was Chain: too damn buggy to be out of sandbox)
Seneca said: [w]hen in Rome, do as the Romans do. When not in Rome, do as the Romans do. You know what this has been taken to mean. EVERYONE makes the same mistake frequently. That is kind of the nature of EVERYONE. The book In Praise of Folly, which actually is taken to be in praise of folly by EVERYONE, was written by Erasmus in grief over the beheading of his friend, Thomas More by Henry VIII. Peter Nannius wrote: Erasmus the glory of our times, lived in the heart of More, More, the sole light of Britian, lived in the heart of Erasmus. The one exchanged life with the other; each lived a life not his own. It is no marvel that with the death of More, Erasmus wished for death, unwilling to live longer. The title word folly is a Latin pun for More and the title actually means In Praise of More, who was recognized as one of the most if not the most erudite (certainly no friend of folly) man in extant Christiandom. Now EVERYONE thinks that the book is in praise of the simple life and, indeed, folly. Plato's The Republic (whose actual title is The City - politeia) is a careful _reductio ad absurdum_ of the idea of a perfect city that suspiciously sounds like the hated Sparta (Socrates took hemlock rather than leave Athens, remember) but this has not stopped EVERYONE from forgetting the admonition in that book to hide behind the walls until the political winds have died down and from deciding that the book attempts to do the opposite, i.e. posit a perfect society based on Spartan principles. EVERYONE takes the New Testament, a book slabbed together and retrofitted from multifarious sources to meet the political ends of Emporer Constantine and his toady Eusebius to be the Word of God itself. EVERYONE also says the Lords Prayer in public, which aside from being an obviously later addition to the Book of Matthew was cautioned by Jesus to be used only in private. EVERYONE is not a good source. EVERYONE is a particulary bad source on the Internet, the home of fluff and deception for small personal triumphs. There, now you have it. ///;-) Jack On Thu, 31 Mar 2005 09:02:07 -0500 (EST), Frank W.

RE: [commons-logging] Problem renaming logfiles

[HttpClient] HttpClient and sendRedirect problem
Hi!! I am using HttpClient to post xml files from my servlet to a JSP/servlet. My application is designed in such a way that have a big XML which I parse and get smaller XMLs and loop through them posting each smaller XML to a JSP. This part works fine. Now, after I post the XML to my JSP/Servlet I want to do a response.sendRedirect within the JSP/Servlet to another URL where I do some processing and then want the control to return to where it has been posting the XML file from, i.e. return the control back to the servlet which does the posting. But once I post the XML to the JSP/Servlet using HttpClient response.sendRedirect doesn't seem to be redirecting me to the other JSP. Any help?? Thanks, Swati __ Do you Yahoo!? Yahoo!

Re: [transaction.locking] Modify the behaviour of the ReadWriteUpgradeLockManager
Hmmm, not quite sure that I get this all right, but to me it seems you
describe the simple read/write locks (without the upgrade step). Is
that possible? If so you could simply use the ReadWriteLockManager.

I have struggled to find what I am doing wrong and have seen plenty of
references to the HttpServletRequest version (1.0) on Google, but nothing
for a Portlet code example version. What have I missed? :) Do I need to
write additional code for one of these classes - is this class and other
classes in the package unfinished? Does anyone have any example (working)
snippets?
Any help you could provide would be greatly appreciated.
Cheers, Pete.
RE: [PortletFileUpload] class compiling error
That's because it isn't a servlet - it's a portlet. Are these files really
necessary? It uses the ActionRequest object, rather than an
HttpServletRequest object - which are very different in a Portal Server. I
have been struggling with this all day and have still not progressed very
far. Has anyone managed to upload a file through a Portlet (JSR 168) or is
this not possible?
Cheers, Pete.

I have struggled to find what I am doing wrong and have seen plenty of
references to the HttpServletRequest version (1.0) on Google, but nothing
for a Portlet code example version. What have I missed? :) Do I need to
write additional code for one of these classes - is this class and other
classes in the package unfinished? Does anyone have any example (working)
snippets?
Any help you could provide would be greatly appreciated.
Cheers, Pete.

Subject: RE: [PortletFileUpload] class compiling error
That's because it isn't a servlet - it's a portlet. Are these files really
necessary? It uses the ActionRequest object, rather than an
HttpServletRequest object - which are very different in a Portal Server. I
have been struggling with this all day and have still not progressed very
far. Has anyone managed to upload a file through a Portlet (JSR 168) or is
this not possible?
Cheers, Pete.

I think the problem is the classpath value. Check that you have tools.jar
and servlet.jar in it.

I would appreciate some assistance in creating a JSR 168 compliant File
Upload Portlet. I have downloaded the 1.1-dev JAR from the commons website
(Nightly build) but seem to be having problems compiling.

DiskFileItemFactory dfif = new DiskFileItemFactory(10240, tmpDir);
...
PortletFileUpload pfu = new PortletFileUpload(dfif);
...
try
{
List fileItems = pfu.parseRequest(request);
Iterator iter = fileItems.iterator();
while (iter.hasNext())
{
FileItem item = (FileItem)iter.next();

Re: [dbcp] Help! getting AbstractMethodError
You should make a list of differences between you new system and the QA setup. Start with VM version, global tomcat jars (including dbcp version) and application specific ones. In this specific case check the database driver jar, make sure you use the same jar everywhere. If you find the sulotion please add it to the wiki FAQ page or let us know. -- Dirk Rumpa Giri wrote: I am unable to figure out why I am getting this following exception. When I do a brand new installation, everything works, but on our QA server installing on top of existing tomcat, and as a part of existing web application, it throws the exception.

Re: [transaction.locking] Modify the behaviour of the ReadWriteUpgradeLockManager
Hi, Selon Oliver Zeigermann [EMAIL PROTECTED]: Hmmm, not quite sure that I get this all right, but to me it seems you describe the simple read/write locks (without the upgrade step). Is that possible? If so you could simply use the ReadWriteLockManager. My lock manager has not exactly the same behaviour as the ReadWriteLockManager and I think looks more like the ReadWriteUpgardeLockManager. I will try to explain what I want to do ;o) In my case : * Read access requires a shared lock (S). * Write access requires an exclusive lock (X). * An upgrade lock (U) supports read with (potential) write access and prevents further shared locks (S) for the same object. An upgrade lock (U) can be converted to an exclusive lock (X) after the release of the existing shared locks or back to a shared lock if no update action is needed (time out). So, the difference is when I have an upgrade lock on a data, it is impossible to obtain shared locks, but locks that are already granted keep going on. With the exclusive lock no other locks can be obtained or exist on the same data. I expect it's more clear? Is it possible to transform the ReadWriteUpgradeLockManager to obtain this ?
