Where is the ConnectPool class?

I am using WSAD 4.0.3 and wanted to use the Microsoft JDBC driver.
But when I try to set the WS server up with connection pooling I am at
a loss as to what the com.microsoft.ETC is to the ConnectionPool
class. What is it called and where is it?
Thanks in advance,

Crickets chirping in the night.......
Sigh I really hate to flame but what can I say. I have been involved with Java development off and on over several years. Granted most of those years have been in the Microsoft world but there have been times and clients that Java was the best solution.
Having worked in both camps, I have to tell you. I have always been sorely disappointed in the so called "community" of Java developers. A question such as the one posed would have generated a good dozen responses by now (48 hours old) within a Microsoft developer forum. Whether the question is basic, simple, obvious or just plain stupid is irrelevant. Either way it would not hinder developers from stating the fact plus the answer.
There can be many reasons, maybe this is not a very active forum. If not then what website would have a quality and active forum?
Maybe the question is viewed as redundant, or too simple to warrant a answer. But when has that stopped a good developer from pointing out the obvious? :-)
Maybe Java, J2EE, etc. is not nearly as widely used as Microsoft's technologes. I know I have certainly seen this to be the case. Microsoft's weakness of being platform specific is in fact its' greatest strength. Everything works, together, seemlessly. No complex interoperatability issues. Open source is in many ways is open sores. With configuration and interoperability being a daunting manual labor intensive task. Case in point seems to be WSAD, works great simple as cake with Websphere Application Server and DB2. Try to use other non-IBM software such as SQL Server then all of a sudden you start slamming your hand in the drawer, repeatedly. I guess it could be the same in trying to use DB2 from .NET but then again, the developer base is there and you WILL get a response from someone who has done it.
Of course, the reason for the lack of response is mostly likely something entirely different. Either way, this response, my response, should get some attention. Maybe.
Sorry for the post, just some frustration I have been having since jumping back into the wonderful world of Java, Servlets and J2EE. Most likely does not help that my previous project was .NET with all its' ease.

Where is the member class?

Hi,
I am Ryan.
Here is a small piece of code.
<pre>
if( error.getClass().equals( SoftErrorException.<b>class</b> ) )
throw new JspException();
</pre>
Can somebody tell me where is the member "class" referred in the object SoftErrorException. I checked in the class "Object" and "Class". I also checked in the Java documentation index. I still could not find it.
Thanks in advance

Ryanclass is not a member. This is part of the language. Also, SoftErrorException is not an Object it is a class. I'm also having a problem finding the documentation for this. I assume it is part of the JLS. ClassName.class is the same as InstanceOfClass.getClass().

Where does the java classes go?

I normally use IntelliJ which automatically puts the java class and the jsp where they are meant to go.
Can some help me.
Can someone please tell me where to put the java class, i have put the jsp pages in the webapps\ROOT but where does the java classes go?

Only a type can be imported. com.database.contactDB resolves to a packageDo you have a package structure that looks like this:

com/database/contactDB/
Because that is what the compiler is saying. Though it may be thrown off by case (see below)
P.S. If you use the jsp:useBean you do not need the import statement which appears to be where the error occurs. (One of the things that makes JSPs so hard to debug is the fact that the error line in the generated java file as referenced above is never the same as the line in the JSP file).

And to be ultra clear - you did compile contactDB from a .java file to a .class file, and the class is called contactDB and not ContactDB correct? The class name is case sensitive and should be the exact same case in the useBean and import statements as in the real class name.

Fixed compile from .class file to a .java file to compile from a .java file to .class file

Where is the anonymous class in this? (lotsa code)

When I compile ThreadPool.java, I get three classes: ThreadPool.class, ThreadPool$WorkerThread.class, and ThreadPool$1.class. I understand the first two, but I can't figure out where the anonymous class is coming from. Could it be some kind of automatically-generated wrapper class caused by the fact that all accesses to the Queue object are within synchronized blocks? Curiosity attacks!
Thanks,
Krum
ThreadPool.java:
package krum.util;
* A thread pool with a bounded task queue and fixed number of worker threads.
public class ThreadPool {
   protected Queue queue;
public ThreadPool(int threads, int taskQueueSize) {
   queue = new Queue(taskQueueSize);
   /* create the worker threads */
   for(int i = 0; i < threads; ++i) {
      Thread t = new Thread(new WorkerThread());
      t.setDaemon(true);
      t.start();
* Queues a task to be executed by this ThreadPool. If the task queue is
* full, the task will run in the calling thread. (Could easily be modified
* to throw an exception instead.)
public void doTask(Runnable task) {
   boolean added = false;
   synchronized(queue) {
      if(!queue.isFull()) {
         queue.add(task);
         added = true;
         queue.notify();
   if(!added) task.run();
* Tests if the task queue is empty. Useful if you want to wait for all
* queued tasks to complete before terminating your program.
public boolean queueEmpty() {
   synchronized(queue) {
      return queue.isEmpty();
private class WorkerThread implements Runnable {
public void run() {
   Runnable task;
   while(true) {
      task = null;
      synchronized(queue) {
         try {
            if(queue.isEmpty()) queue.wait();
            else task = (Runnable)queue.getNext();
         } catch(InterruptedException e) { break; }
      if(task != null) task.run();
} /* end inner class WorkerThread */
} /* end class ThreadPool */Queue.java:
package krum.util;
* Implements a FIFO queue for storage and retrieval of objects. This class
* is not synchronized.
public class Queue {
     /** circular buffer containing queued objects */
     protected Object[] queue;
     /** index of next object to be returned */
     protected int nextReturn;
     /** index in which to store next object inserted */
     protected int nextInsert;
public Queue(int capacity) {
     queue = new Object[capacity];
     nextInsert = 0;
     nextReturn = 0;
public boolean isEmpty() { return(queue[nextReturn] == null); }
public boolean isFull() { return(queue[nextInsert] != null); }
public void add(Object obj) throws QueueException {
     if(queue[nextInsert] == null) {
          queue[nextInsert] = obj;
          ++nextInsert;
          nextInsert %= queue.length;
     } else throw new QueueException();
public Object getNext() throws QueueException {
     if(queue[nextReturn] != null) {
          Object obj = queue[nextReturn];
          queue[nextReturn] = null;
          ++nextReturn;
          nextReturn %= queue.length;
          return obj;
     } else throw new QueueException();
} /* end class Queue */QueueException.java:
package krum.util;
public class QueueException extends RuntimeException { }

I can't explain why it happens, but I've seen this
behaviour before. I found that it was to do with an
inner class (WorkerThread in your code) having a
private constructor - if I made my inner class
constructor at least package (default) access, then
the anonymous class was no longer created.
The generated default constructor for a class has the
same access modifier as the class, so in your example,
the default constructor that the compiler generates is
private.
I suspect the problem will go away if you either:
1. Remove the private modifier from the WorkerThread
class declaration.
or:
2. Add a no-args constructor to the WorkerThread
class, and don't specify an access modifier.Yes, the reason is the private constructor. After decompile using JAD, the reason seems to be: if a private inner class does not explicitly have any constructor, a default no-arguments private constructor is created, and seems this default constructor can't be accessed directly (in source code, it can). So, another no-private constructor (package accessible) is created automatically (with an argument of Object's type), and the
new WorkThread();is actually like this:
new WorkThread(null);
private class WorkThread implements Runnable{
   private WorkThread(){}
   WorkThread(Object obj) {
      this();
}and I would guess it's using anonymous class tech to achieve this like:
new WorkThread(null) {
   WorkThread(Object obj){
      this();
}The JLS should have specified this situation.

Where is the WebService class located in the Flex SDK?

You must have a maintenance contract. You can call your Sales rep or Support to work this out.

Where is the Debug Class

Does anyone know what package the Debug Class is in? I searched through the Java API, but I couldn't find it...

There are also third-party debuggers. Most (all?) IDEs come with a debugger. Arguably you really couldn't call it an IDE if it didn't have a debugger.
I suppose it's typical for interpreted languages to have a separate class or module to be the debugger, whereas compiled languages tend to require a separate program. (Opinions?) In Java the JVM can be interfaced to an external program (eg jdb) to do debugging.

Where is the DefaultRealmImpl class?

Hello all,
I have been getting the java.lang.ClassNotFoundException:
weblogic.security.acl.DefaultRealmImpl. I have been looking around for the
class in order to add it to my classpath, but I have not been able to locate
it. Does anyone know where, e.g. which jar, to find it? Is this a
classpath issue or is there something deeper here? I noticed that several
other people were getting the same error.
BTW I am running jdk1.3, weblogic 5.1, and I am on NT.
Thanks,
Lee

Are you upgrading from an earlier version of WLS to 5.1? If so, you

Hi, I have exactly the same problem. I not upgrading, I use 5.1 sp5. And

As far as I understand, the problem is that somebody hardcoded the wrong
package name of the DefaultRealmImpl (it should be
weblogic.security.acl.internal.DefaultRealmImpl).
Question: inside my code I use this line to get RDMBS realm:
RDBMSRealm realm = (RDBMSRealm)Realm.getRealm
(RDBMSRealm.REALM_NAME);
The constructor of RDMBS realm uses super(REALM_NAME). Maybe I should
use some other name? If you create DefaultRealmImpl in case you can't
find the specified realm, just tell me how to correctly find/register
custom realm. I tried passing fully qualified name of the realm class,
but it didn't help.

Where should the support classes of servlets, JSPs and EJBs be placed

          Hi
          Could you please tell me where the support classes (simple
          java classes) used by servlets, JSPs and EJBs should be placed.
          I find that my application does not work if I place all the
          support classes of a servlet under $MYSERVER/clientclasses. I need to place some in $MYSERVER/clientclasses and some in
          $MYSERVER/servletclasses. But I figured this out my trial and error and I could not find any logical explanation why some of them should go into $MYSERVER/clientclasses and others into
          $MYSERVER/servletclasses.

This looks like a classpath issue. The aurora directory only exists in the JAR file where the classes are stored. In this case they are in the

Where is the Vector class? Can't use it.

Hello!
I've downloaded Flex Builder 3 Trial from Adobe's website.
Now I want to use the Vector class, but this code for example:
var v:Vector.<String>;
v = new Vector.<String>();
Gives me this error:
1046: Type was not found or was not a compile-time constant: Vector.
At the IDE, going to
Window -> Preferences -> Flex -> Installed Flex SDKs
I can see that I have Flex 3.2 SDK.
Even more than that: When I search for "Vector" in the help ("Adobe® Flex™ 3 Language Reference") I can see all the details about Vector.
What can I do?
I'd like to avoid installing any newer SDKs due to all the bugs I see listed here in the forums.
Thank you!

It looks like you are trying to type Java code in Flex Builder. Flex applications are generally built using ActionScript.
These docs might help you learn ActionScript:

And each .class file must be in a directory that reflects its package. So in your example ProjectGUI.class must be in the directory projectRFID/ inside the .jar file.
