Sample Web Interaction code

hi sun community,
I just want to interact with my own website through j2me. Is it possible to do that ?
if yes, then what are the steps to do that and what are the APIs which will be used, and the major question is how do i find the different APIs available..
Please help me asap !
thanks in advance :)

Yes the is possible.
First define the contract between your mobile application and your site. You will need to consider the protocol including authentication and authorization, efficiency, etc.
Please see the Java ME section of this site. Sun offers tutorials on midlet/server communication.

How do you create an interactive floor plan in flash using AS2?

I am attempting to make an interactive floor plan. I am sure that I have done it wrong, I am new to flash. So far I have outlined the rooms that I want to make "hot spots", turned them into buttons. Then I selected all the buttons and turned it into a movie clip called "mcbtns". I then turned it into a movie clip again, named it "mcbtninside"; this is where I house all of my buttons which have instance names "btn1" thru "btn11".
The images that corrospond with the rooms of floor plan are housed in a movie clip named "mcPhotos". On the timeline the photos are place at 10 frame increments, and the Action Script time line above them has frame names "img1" thru "img11", which corrospond with the photos every 10 frames. Frame 1 on the AS line has the code stop();
Now back to Scene 1...
Scene 1 frame 1 on the Action Script line I have in the following script:
mcPhotos._visible = false;
this.mcbtns.onRollOver = function() {
     mcPhotos._visible = true;
this.mcbtns.onRollOut = function() {
     mcPhotos._visible = false;
stop();
In frame 1 on the Action Script line within "mcbtninside" I have the following script:
var frameNum:Number;
function photoChange(){
     _root.photos.gotoAndPlay("img" + frameNum);
btn1.onRollOver = function(){
     frameNum = 1;
     photoChange():
btn2.onRollOver = function(){
     frameNum = 2;
     photoChange():
The code continues thru btn11.
So I am sure that I have gone wrong in many places. If someone could lead me in the right direction I would greatly appreciate it.

Take all the interactive code off the mcbtns movieclip, and even get rid of that clip if it serves no other purpose than to collect all the rooms. Assign the code to make the photos appear / disappear to all of the rooms... (what's shown below assumes mcbtns went away and the rooms are on the same timeline as the photos mc)
btn1.onRollOver = function(){
     frameNum = 1;
     photoChange():
     mcPhotos._visible = true;
btn2.onRollOver = function(){
     frameNum = 2;
     photoChange():
     mcPhotos._visible = true;
btn1.onRollOut = btn2.onRollOut = function(){
     mcPhotos._visible = false;
If you keep the mcbtns movieclip, then your button code would have to use a _parent reference to target the mcPhotos... _parent,mcPhotos.visible = etc... actually, I'm not sure where things lie in that aspect, so hopefully you can figure out the correct targeting

Url link in flash page flip book

I am very inexperienced at what I am trying to accomplish.
I have created a flip book in flash. On a page in the book I made a button that is a link to an external url. When I place the the swift file of that page on my webstie, the link works. I have made a link from my homepage to the flipbook. But when I open the flip book the url link does not work.
Does anyone out there know what's wrong?
thanks

If the flip page the swf is in has interactive code asigned to it, such as whatever you use to flip the page, it could be blocking access to any clickable objects in the swf file.

HOWTO: Using a BC4J Application Module in an Stateless EJB Session Bean

HOWTO: Using a BC4J Application Module in an Stateless EJB Session Bean
by Steve Muench
Overview
BC4J provides automatic facilities for deploying any application module as a stateful EJB session bean. If you want to leverage the features of your BC4J application module from a stateless EJB session bean, it's not automatic but it is straightforward to implement. This howto article explains the details.
For our example, we will create a stateless EJB session bean that uses a container-managed transaction. To keep things simple, let's assume the session bean has a single public method on its remote interface named createDepartment() with the following signature:
public void createDepartment(int id, String name, String loc) throws AppException
AppException is an example of an application-specific exception that our method will throw if any problems arise during its execution.The goal of this article is to illustrate how to use the BC4J application module named com.example.hr.HRApp as part of the implementation of this createDepartment method on our stateless enterprise bean. Let's assume that the HRApp application module has a view object member named Departments, based on the com.example.hr.DeptView view object, based on the familiar DEPT table and related to the com.example.hr.Dept entity object so our view can be updateable.
Creating the Stateless Session Bean
We can start by using the JDeveloper Enterprise Bean wizard to create a new stateless session bean called StatelessSampleEJB implemented by:[list][*]com.example.StatelessSampleEJBBean (Bean class)[*]com.example.StatelessSampleEJBHome (Home interface)[*]com.example.StatelessSampleEJB (Remote interface)[list]
We then use the EJB Class Editor to add the createDepartment method to the remote interface of StatelessSampleEJB with the signature above. We edit the remote interface to make sure that it also reflects that the createDepartment method thows the AppException like this:
package com.example;
import javax.ejb.EJBObject;
import java.rmi.RemoteException;
public interface StatelessSampleEJB extends EJBObject {
void createDepartment(int id, String name, String loc)
throws RemoteException,AppException;
}Before we start adding BC4J into the picture for our implementation, our StatelessSampleEJBBean class looks like this:
package com.example;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;
public class StatelessSampleEJBBean implements SessionBean {
public void ejbCreate(){}
public void ejbActivate(){}
public void ejbPassivate(){}
public void ejbRemove(){}
public void setSessionContext(SessionContext ctx){
public void createDepartment(int id, String name, String loc)
throws AppException {
    // TODO: Implement method here
}We can double-click on the ejb-jar.xml file in our project to see the XML deployment descriptor for the bean we just created:
<ejb-jar>
   <enterprise-beans>
      <session>
         <description>Session Bean ( Stateless )</description>
         <display-name>StatelessSampleEJB</display-name>
         <ejb-name>StatelessSampleEJB</ejb-name>
         <home>com.example.StatelessSampleEJBHome</home>
         <remote>com.example.StatelessSampleEJB</remote>
         <ejb-class>com.example.StatelessSampleEJBBean</ejb-class>
         <session-type>Stateless</session-type>
         <transaction-type>Container</transaction-type>
      </session>
   </enterprise-beans>
</ejb-jar>We need to add the extra <assembly-descriptor> section in this file to indicate that the createDepartment method will require a transaction. After this edit, the ejb-jar.xml file looks like this:
<ejb-jar>
   <enterprise-beans>
      <session>
         <description>Session Bean ( Stateless )</description>
         <display-name>StatelessSampleEJB</display-name>
         <ejb-name>StatelessSampleEJB</ejb-name>
         <home>com.example.StatelessSampleEJBHome</home>
         <remote>com.example.StatelessSampleEJB</remote>
         <ejb-class>com.example.StatelessSampleEJBBean</ejb-class>
         <session-type>Stateless</session-type>
         <transaction-type>Container</transaction-type>
      </session>
   </enterprise-beans>
   <assembly-descriptor>
      <container-transaction>
         <method>
            <ejb-name>StatelessSampleEJB</ejb-name>
            <method-name>createDepartment</method-name>
            <method-params>
               <method-param>int</method-param>
               <method-param>java.lang.String</method-param>
               <method-param>java.lang.String</method-param>
            </method-params>
         </method>
         <trans-attribute>Required</trans-attribute>
      </container-transaction>
   </assembly-descriptor>
</ejb-jar>
Aggregating a BC4J Application Module
With the EJB aspects of our bean setup, we can proceed to implementing the BC4J application module aggregation.
The first thing we do is add private variables to hold the EJB SessionContext and the instance of the aggregated BC4J ApplicationModule, like this:
// Place to hold onto the aggregated appmodule instance
transient private ApplicationModule _am = null;
// Remember the SessionContext that the EJB container provides us
private           SessionContext    _ctx = null;and we modify the default, empty implementation of the setSessionContext() method to remember the session context like this:
public void setSessionContext(SessionContext ctx){ _ctx = ctx; }We add additional constants that hold the names of the J2EE datasource that we want BC4J to use, as well as the fully-qualified name of the BC4J application module that we'll be aggregating:
// JNDI resource name for the J2EE datasource to use
private static final String DATASOURCE = "jdbc/OracleCoreDS";
// Fully-qualified BC4J application module name to aggregate
private static final String APPMODNAME = "com.example.hr.HRApp";We expand the now-empty ejbCreate() and ejbRemove() methods to create and destory the aggregated instance of the BC4J application module that we'll use for the lifetime of the stateless session bean. When we're done, ejbCreate() it looks like this:
public void ejbCreate() throws CreateException {
try {
    // Setup a hashtable of environment parameters for JNDI initial context
    Hashtable env = new Hashtable();
    env.put(JboContext.INITIAL_CONTEXT_FACTORY,JboContext.JBO_CONTEXT_FACTORY);
    // NOTE: we want to use the BC4J app module in local mode as a simple Java class!
    env.put(JboContext.DEPLOY_PLATFORM, JboContext.PLATFORM_LOCAL);
    env.put(PropertyConstants.INTERNAL_CONNECTION_PARAMS,DATASOURCE);
    // Create an initial context, using this hashtable of environment params
    InitialContext ic = new InitialContext(env);
    // Lookup a home interface for the application module
    ApplicationModuleHome home = (ApplicationModuleHome)ic.lookup(APPMODNAME);
    // Using the home, create the instance of the appmodule we'll use
    _am = home.create();
    // Register the BC4J factory to handle EJB container-managed transactions
    registerContainerManagedTransactionHandlerFactory();
catch(Exception ex) {
     ex.printStackTrace();
    throw new CreateException(ex.getMessage());
}and ejbRemove() looks like this:
public void ejbRemove() {
try {
    // Cleanup any appmodule resources before getting shutdown
    _am.remove();
catch(JboException ex) { /* Ignore */ }
}The helper method named reigsterContainerManagedTransactionHandlerFactory() looks like this:
private void registerContainerManagedTransactionHandlerFactory() {
SessionImpl session = (SessionImpl)_am.getSession();
session.setTransactionHandlerFactory(
    new TransactionHandlerFactory() {
      public TransactionHandler createTransactionHandler() {
        return new ContainerManagedTxnHandlerImpl();
      public JTATransactionHandler createJTATransactionHandler() {
        return new ContainerManagedTxnHandlerImpl();
}The last detail is to use the BC4J appmodule to implement the createDepartment() method. It ends up looking like this:
public void createDepartment(int id, String name, String loc)
throws AppException {
try {
    // Connect the AM to the datasource we want to use for the duration
    // of this single method call.
    _am.getTransaction().connectToDataSource(null,DATASOURCE,false);
    // Use the "Departments" view object member of this AM
    ViewObject departments = _am.findViewObject("Departments");
    // Create a new row in this view object.
    Row newDept = departments.createRow();
    // Populate the attributes from the parameter arguments.
    newDept.setAttribute("Deptno", new Number(id));
    newDept.setAttribute("Dname", name);
    newDept.setAttribute("Loc", loc);
    // Add the new row to the view object's default rowset
    departments.insertRow(newDept);
    // Post all changes in the AM, but we don't commit them. The EJB
    // container managed transaction handles the commit.
    _am.getTransaction().postChanges();
catch(JboException ex) {
    // To be good EJB Container-Managed Transaction "citizens" we have
    // to mark the transaction as needing a rollback if there are problems
    _ctx.setRollbackOnly();
    throw new AppException("Error creating dept "+ id +"\n"+ex.getMessage());
finally {
    try {
      // Disconnect the AM from the datasource we're using
      _am.getTransaction().disconnect();
    catch(Exception ex) { /* Ignore */ }
Building a Test Client
With the EJB-Tier work done, we can build a sample client program to test this new stateless EJB Session Bean by selecting the bean in the Oracle9i JDeveloper IDE and choosing "Create Sample Java Client" from the right-mouse menu.
When the "Sample EJB Client Details" dialog appears, we take the defaults of connecting to embedded OC4J container. Clicking the (OK) button generates the following test class:
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
import com.example.StatelessSampleEJB;
import com.example.StatelessSampleEJBHome;
public class SampleStatelessSampleEJBClient {
public static void main(String [] args) {
    SampleStatelessSampleEJBClient sampleStatelessSampleEJBClient =
       new SampleStatelessSampleEJBClient();
    try {
      Hashtable env = new Hashtable();
      env.put(Context.INITIAL_CONTEXT_FACTORY,
              "com.evermind.server.rmi.RMIInitialContextFactory");
      env.put(Context.SECURITY_PRINCIPAL, "admin");
      env.put(Context.SECURITY_CREDENTIALS, "welcome");
      env.put(Context.PROVIDER_URL,
              "ormi://localhost:23891/current-workspace-app");
      Context ctx = new InitialContext(env);
      StatelessSampleEJBHome statelessSampleEJBHome =
           (StatelessSampleEJBHome)ctx.lookup("StatelessSampleEJB");
      StatelessSampleEJB statelessSampleEJB;
      // Use one of the create() methods below to create a new instance
      // statelessSampleEJB = statelessSampleEJBHome.create();
      // Call any of the Remote methods below to access the EJB
      // statelessSampleEJB.createDepartment( int id, java.lang.String name, java.lang.String loc );
    catch(Throwable ex) {
      ex.printStackTrace();
}We uncomment the call to the create() method and add a few calls to the createDepartment() method so that the body of the test program now looks like this:
// Use one of the create() methods below to create a new instance
statelessSampleEJB = statelessSampleEJBHome.create();
// Call any of the Remote methods below to access the EJB
statelessSampleEJB.createDepartment( 13, "Test1","Loc1");
System.out.println("Created department 13");
statelessSampleEJB.createDepartment( 14, "Test2","Loc2");
System.out.println("Created department 14");
try {
// Try setting a department id that is too large!
statelessSampleEJB.createDepartment( 23456, "Test3","Loc3");
catch (AppException ax) {
System.err.println("AppException: "+ax.getMessage());
}Before we can successfully run our SampleStatelessSampleEJBClient we need to first run the EJB bean that the client will try to connect to. Since Oracle9i JDeveloper supports local running and debugging of the EJB-Tier without doing through a full J2EE deployment step, to accomplish this prerequisite step we just need to right-mouse on the StatelessSampleEJB node in the System Navigator and select "Run". This starts up the embedded OC4J instance and runs the EJB right out of the current out path.Finally, we can run the SampleStatelessSampleEJBClient, and see the output of the test program in the JDeveloper log window:
Created department 13
Created department 14
AppException: Error creating dept 23456
JBO-27010: Attribute set with value 23456 for Deptno in Dept has invalid precision/scale
Troubleshooting
One error that might arise while running the example is that the database connection information in your data-sources.xml for the jdbc/OracleCoreDS datasource does not correspond to the database you are trying to test against. If this happens, then double-check the file .\jdev\system\oc4j-config\data-sources.xml under the JDeveloper installation home directory to make sure that the url value provided is what you expect. For example, to work against a local Oracle database running on your current machine, listening on port 1521, with SID of ORCL, you would edit this file to have an entry like this for jdbc/OracleCoreDS :
<data-source
    class="com.evermind.sql.DriverManagerDataSource"
    name="OracleDS"
    location="jdbc/OracleCoreDS"
    xa-location="jdbc/xa/OracleXADS"
    ejb-location="jdbc/OracleDS"
    connection-driver="oracle.jdbc.driver.OracleDriver"
    username="scott"
    password="tiger"
    url="jdbc:oracle:thin:@localhost:1521:ORCL"
    inactivity-timeout="30"
/>This is the data-sources.xml file that gets used by the embedded OC4J instance running in JDeveloper.
Conclusion
Hopefully this article has illustrated that it is straightforward to utilize the full power of BC4J in local mode as part of your EJB Stateless Session Beans using container-managed transaction. This example illustrated a single createDepartment method in the enterprise bean, but by replicating the application module interaction code that we've illustrated in createDepartment, any number of methods in your stateless session bean can use the aggregated application module instance created in the ejbCreate() method.

Hi Steve, It4s me again;
About the question I made, I tried with a single assembly-descriptor tag and a single container-transaction tag in the deployment descriptor of the session bean and these were the results.
java.lang.NullPointerException
     void com.evermind.server.rmi.RMIConnection.EXCEPTION_ORIGINATES_FROM_THE_REMOTE_SERVER(java.lang.Throwable)
     java.lang.Object com.evermind.server.rmi.RMIConnection.invokeMethod(com.evermind.server.rmi.RMIContext, long, long, java.lang.reflect.Method, java.lang.Object[])
     java.lang.Object com.evermind.server.rmi.RemoteInvocationHandler.invoke(java.lang.Object, java.lang.reflect.Method, java.lang.Object[])
     java.lang.Object com.evermind.server.rmi.RecoverableRemoteInvocationHandler.invoke(java.lang.Object, java.lang.reflect.Method, java.lang.Object[])

     void SamplemdeController.envolturaControlEJBClient.main(java.lang.String[])
Then I tried with multiple assembly-descriptor tags each with a single container-transaction tag and the results were:
java.lang.NullPointerException
     void com.evermind.server.rmi.RMIConnection.EXCEPTION_ORIGINATES_FROM_THE_REMOTE_SERVER(java.lang.Throwable)

Finally I tried with a single assembly-descriptor and multiple container tags and the results were:

Processing the multibyte chars in the [b]cluster[/b] environment.

Hi
I have a problem while processing the multibyte chars in the cluster environment.
I have 2 pages(JSP) where one is a handler jsp. I entered the multibyte say HINDHI language chars in one jsp, and in the 2nd jsp I used the request.getParameter() method.
In non-clustered environment, in the 2nd jsp the chars are shown as (???????) . But in clustered environment, they were shown as "�� ".
I have written database interaction code in the 2nd page, the data inserted here is not of expected.
Note: Database is UTF-8 supported and I tried with all databases(DB2, Oracle,MSSQl and Syabse)
This problem is occuring in the clustered environment only with J2SE 5.0
Please provide your thoughts..........
Thanks in advance,
Sri

I have multiple movie clips on stage (all in separate layers, of course) as well as buttons on stage to play each movie clip. There are buttons inside each movie clip. The problem is that the buttons inside the top layered movie clip work, but the others in the movie clips below don't.
This is frustrating!! Can anyone help???

It shouldn't matter which layer things are on. If they are separate movielcips, one should not impact another. What version of actionscript are you using? Do any of the movieclips have mouse interactive code assigned to them?

Font not consistent in movie clips

Hi,
Can't sort this out, I've got a movie clip where I've used the embedded text option (static text) it looks fine but in another MC (same .fla) I use the same Font (embedded) but it looks different !! I've checked the setting in the text properties but cannot get it to look the same.
My set up is, Flash Pro CS5 running on Win 7 64 bit.
Can someone help me out here please?
Thanks, Pete

BMP in EJB 3.0

I've been on the google for a few days now and haven't found one single notion on bean-managed persistence in EJB 3.0 specification. Even the official specification PDFs don't mention it :(
Help! I need BMP! Does anybody know what's the situtation in EJB 3.0? Can I and how mark an entity bean to be bean-managed persistent and use ejbLoad and ejbStore functions like in the EJB 2.0 or something like that?
Tnx in advance,
Igor

Hi Sumit,
The direction the spec took was to define a completely new persistence model rather than try to retrofit the old BMP/CMP model. As with all Java EE releases, all requirements supported in previous releases of the platform continue to be supported. That's why you can continue to choose to develop using BMP if you'd like.
However, there is no architected relationship between the Java Persistence API and BMP/CMP. One thing the Java Persistence API and CMP have in common is the belief that all database interaction code should be perfomed by the system layer and not reside in the application.
That's why you don't see BMP-like features within the new Persistence API. In addition, Entity classes developed using the Java Persistence API are not EJB components. The Java Persistence API can be used from any Java EE component (EJB, web component, Application Client) and from J2SE.
The Java Persistence API does define many lifecycle callbacks events (e.g. @PrePersist, @PreUpdate, etc.) that can be delivered to the Entity class. However, these are intended for performing tasks other than direct interaction with the persistent store.

Converting AS3 to AS2. Some movieclip buttons not working.

25 movieclip buttons in frame 126 maintimeline. Buttons are on top layer above all other content.
Buttons 1_1, 2_1, 3_1, 4_1, and 5_1 work. All buttons have correct instance name. The buttons are in a 5x5 grid. Hence the naming convention of column_row. So all row 1 buttons are working. Do not get hand cursor over any of the other buttons. This is totally baffling. I am using Flash CS4. The file is saved as CS3 and the publish settings are AS2, Flash player 8.
Here is the AS for frame 126.
stop();
trace("tScore = "+tScore);
trace("i = "+i);
if (i == 0) {
    i++;

videoBtn4_5.onRelease = function() {
    gotoAndStop(127);
    videoBtn4_5.play();
videoBtn5_5.onRelease = function() {
    gotoAndStop(127);
    videoBtn5_5.play();

You can probably reduce all that interaction code to a loop...
for(i=1; i<6; i++){
   for(k=1; k<6; k++){
      this["videoBtn"+i+"_"+k].onRelease = function() {
          gotoAndStop(127);
          this.play();
As for why movng the buttons to another layer fixed anything, it will not have mattered. Whatever fixed the problem will remain a mystery. It could have been an issue with instance names/frames since you are at frame 126 for some reason. If you transition the buttons into place, that might be related to what the problem was.

Parallelized for loop. Searching for a one-line solution

Hi.
In an usual day I do a lot of for loops inside of command line. But I noted that my loops don't use the full power of my dual core processor, they only use one processor.
A lot of the loops I do have independent interactions in the sense that a interaction code don't need the results of another interaction. This is the simplest problem in multiprocessing, I only need to execute N process in parallel.
I'm searching for a one-line solution that I can use in place of a 'for i in *.txt; do echo $i;done'. With one-line I means that can be used as one-line but the implementation can be longer. And can be in any programming language.
For now I'm using the following small python solution (the smallest I could get)
#!/usr/bin/env python
# -*- coding: utf-8 -*-
from multiprocessing import Pool
from glob import glob
from subprocess import call
def f(x):
call(['asy', '-f', 'png', '-render=0', x])
pool = Pool(processes=4)
pool.map(f, glob('*.asy'))
But I like something that can be integrated in my "shell life". Anyone know a solution for my problem?

Buttons in an overlay

Hi all
Recently I created a simple flash text card animation with arrows allowing the user to scoll through the different cards. I wanted to go a step further and make an overlay so when the user rolls over it, it would expand showing a variety of buttons for them to click and link off to in different places
this is where my problem began. I created to overlay as a movie clip and when a small arrow is rolled over the movie clip overlay_mc plays and expands to reveal the buttons and the rollout function causes it to contract. The buttons however are un-clickable and after some research i discovered this is because the overlay_mc clip acts as a layer over the buttons.
Is there anyway I can create an overlay with the buttons remaining active? Help greatly appreciated
Thanks!

If you make the background of your movieclip the object with the rollover/rollout code, then you can have your buttons sitting a layer above it where they will be fully accessible. You will have to add the rollover/rollout code to the buttons as well because when you rollover them you rollout of the background.
Another way to do this would be to use AS3 where you can do all of your interactive code outside of the movieclip.

Casting a JDBC resultSet to VO RowSet?

Is it possible to somehow transform a plain vanilla jdbc ResultSet to a VO RowSet? (Of course without iterating!) Either by passing the entire object (with all rows intact) or by casting?
Thanks

PS. Rob, you know why I want to do this, right<g>?

We use JDBC to access the database internally. BC4J automates a best-practice use of JDBC PreparedStatements and ResultSet's for you without your having to worry about remembering the low-level details.
Our generic JDBC-interaction code worries about consistently applying the best-practice and highest-performance JDBC techniques for you. When we discover a further improvement and implement it, all of your view objects immediately benefit in the next release.
We had a team in Oracle Applications who claimed they could read large amounts of data faster with hand-coded JDBC than with BC4J. They weren't using BC4J in the optimal way and I illustrated by modifying their benchmark how to make BC4J be faster than hand-coded raw use of JDBC.
Their benchmark wasn't really comparing apples to apples, so I made sure they were comparing roughly equivalent amounts of work before we could conclude what was better.

Installing PCI-MIO-16XE-10

I am completely new to National Instruments and/or LabView. I need to do some project development with the PCI-MIO-16XE-10 board.
I need to install the board. Where can I find up-to-date drivers?
Also:
What is Measurement Studio? Should I use it ?
The purpose of this excercise is to develop a program for a medical application with extensive test of parameters and then dumping everything into firmware that will run a Microchip controller.

Hi Mentamax,
To find the latest drivers available for your DAQ board, check out our website at DAQ Driver Support Page
Measurement Studio is a suite of native measurement and automation controls, tools, and class libraries for Visual Studio .NET and Visual Studio 6.0. Measurement Studio dramatically reduces application development time with ActiveX and .NET controls, advanced analysis libraries, scientific user interface controls, mewizards, interactive code designers, and highly extensible classes.
There is a great application note on our website that talks about all the benefits of using Measurement Studio. I found it really helpful and its a great resource.

Tortured by Dr. Watson.

I m running java servlets here on Windows NT workstation with service pack 6. Now I m encountering an error of Dr. Watson everytime i run the servlets which has the Database-Interaction code. The error states that it was caused due to java.exe application. For ur information, I m using jdk1.2.2 & jsdk2.1 for the development. I also tried installing Tomcat 3.3 instead of jsdk2.1, but no good. I tried to search about this. All i can find was that this error can be eliminated by using type 4 drivers. I downloaded some type 3 drivers. But well was unsuccessful in making them to run, 'coz at some or other point they also showed their affinity towards Dr. Watson. So can u plz guide me as to what should i do ? I tried to search for those type IV drivers for Access 97, but cant find it ....

You have an environment problem and is probably not directly related to the database access.
First you might try uninstalling and re-installing java.
Second you might want to search the jdbc forum where it suggests that updating MDAC might help.
There is no such thing as a type 4 driver for MS Access. By definition, since there is no MS Access 'server', there can't be a type 4 driver.
