Lost in the deep sea of Java !
I was fairly into Java development and had done some programming using release 1.1. But that was until 1999. Subsequently I changed job and became engrossed with new work requirement (no Java related work there). As a result I've now lost a complete track of the happenings in the Java world, i.e. what are the various new technologies, new developments, releases, products, platforms, news, etc.
Now I am seriously trying to jump in back to the scene. But I find the current scene as somewhat incomprehesibile. What I am now looking for right now is a single source (maybe a web source, or a Book) that will give me an overview of what all the various Java technologies, platforms, etc. are availabe and what to they mean to me as a Developer AND/OR User.
Any help with URLs, real good books, etc. is welcome.
TIA

You mean you want an overview that says "Java Beans do this; Enterprise Beans do that; . . ."?
If that's the case, try your nearest ultra-large bookstore. Get a cuppa that over-priced but very good java, and sit down with a stack of java books and start reading intros and first chapters. By the end of a day you'll know servlets from doclets, beans from enterprise beans, JDBC from JNI, etc.
Good luck.

The hard disc of my laptop has crashed and i lost all the data. Now I want to take back up of my I phone and transfer contacts , messages and music etc back into my laptop , how can I do that. Also let me know how I can transfer the contacts into Windows contacts from I phone. Pl help
Your content will only be where you put it. It has always been very basic to always maintain a backup copy of your computer.
You can transfer itunes purchases from your iphone: File>Device>Transfer purchases.
You can import your pics taken with the iphone as you would with any digital camera.
You can e-mail the other pics to yourself, they will never be of the original quality.
You can out a unique contact and calendar entry on the computer. You should get the option to merge the data when you sync. -
When I create an EJB Transport Business Service, after selecting the jar that has the EJB 2.1 artefacts (Remote, Home, etc) the oepe plugin fails and can't continue.
As I understand it seems that there is a problem with the classpath of ant build.xml that oepe creates inside folder /tmp/alsbejbtransport/ to compile the bs and generate the wsdl. I checked if tools.jar is in the classpath (in eclipse) and is included, so I can't figure out wich is the problem.
I found this in Oracle, but not helps solve the problem:
BEA-398120
Error: The WSDL for the typed transport endpoint could not be accessed.
Description
There was a problem retrieving the WSDL from the typed transport service endpoint at the time of service registration
Action
Contact technical support
This is the the full stacktrace that shows eclipse.
Generate : Error during generation of the WSDL:

How to create a report with data using the Crystal Reports for Java SDK
Hi,
How do I create a report with data that can be displayed via the Crystal Report for Java SDK and the Viewers API?
I am writing my own report designer, and would like to use the Crystal Runtime Engine to display my report in DHTML, PDF, and Excel formats. I can create my own report through the following code snippet:
ReportClientDocument boReportClientDocument = new ReportClientDocument();
boReportClientDocument.newDocument();
However, I cannot find a way to add data elements to the report without specifying an RPT file. Is this possible? I seems like it is since the Eclipse Plug In allows you to specify your database parameters when creating an RPT file.
is there a way to do this through these packages?
com.crystaldecisions.sdk.occa.report.data
com.crystaldecisions.sdk.occa.report.definition
Am I forced to create a RPT file for the different table and column structures I have?
Thank you in advance for any insights.
Ted JenneyHi Rameez,
After working through the example code some more, and doing some more research, I remain unable to populate a report with my own data and view the report in a browser. I realize this is a long post, but there are multiple errors I am receiving, and these are the seemingly essential ones that I am hitting.
Modeling the Sample code from Create_Report_From_Scratch.zip to add a database table, using the following code:
<%@ page import="com.crystaldecisions.sdk.occa.report.application.*"%>
<%@ page import="com.crystaldecisions.sdk.occa.report.data.*"%>
<%@ page import="com.crystaldecisions.sdk.occa.report.document.*"%>
<%@ page import="com.crystaldecisions.sdk.occa.report.definition.*"%>
<%@ page import="com.crystaldecisions.sdk.occa.report.lib.*" %>
<%@ page import = "com.crystaldecisions.report.web.viewer.*"%>
<%
try {
ReportClientDocument rcd = new ReportClientDocument();
rcd.newDocument();
// Setup the DB connection
String database_dll = "Sqlsrv32.dll";
String db = "qa_start_2012";
String dsn = "SQL Server";
String userName = "sa";
String pwd = "sa";
// Create the DB connection
ConnectionInfo oConnectionInfo = new ConnectionInfo();
PropertyBag oPropertyBag1 = oConnectionInfo.getAttributes();
// Set new table logon properties
PropertyBag oPropertyBag2 = new PropertyBag();
oPropertyBag2.put("DSN", dsn);
oPropertyBag2.put("Data Source", db);
// Set the connection info objects members
// 1. Pass the Logon Properties to the main PropertyBag
// 2. Set the Server Description to the new **System DSN**
oPropertyBag1.put(PropertyBagHelper.CONNINFO_CRQE_LOGONPROPERTIES, oPropertyBag2);
oPropertyBag1.put(PropertyBagHelper.CONNINFO_CRQE_SERVERDESCRIPTION, dsn);
oPropertyBag1.put("Database DLL", database_dll);
oConnectionInfo.setAttributes(oPropertyBag1);
oConnectionInfo.setUserName(userName);
oConnectionInfo.setPassword(pwd);
// The Kind of connectionInfos is CRQE (Crystal Reports Query Engine).
oConnectionInfo.setKind(ConnectionInfoKind.CRQE);
// Add a Database table
String tableName = "Building";
Table oTable = new Table();
oTable.setName(tableName);
oTable.setConnectionInfo(oConnectionInfo);
rcd.getDatabaseController().addTable(oTable, null);
catch(ReportSDKException RsdkEx) {
out.println(RsdkEx);
catch (Exception ex) {
out.println(ex);
%>
Throws the exception
com.crystaldecisions.sdk.occa.report.lib.ReportSDKException: java.lang.NullPointerException---- Error code:-2147467259 Error code name:failed
There was other sample code on SDN which suggested the following - adding the table after calling table.setDataFields() as in:
String tableName = "Building";
String fieldname = "Building_Name";
Table oTable = new Table();
oTable.setName(tableName);
oTable.setAlias(tableName);
oTable.setQualifiedName(tableName);
oTable.setDescription(tableName) ;
Fields fields = new Fields();
DBField field = new DBField();
field.setDescription(fieldname);
field.setHeadingText(fieldname);
field.setName(fieldname);
field.setType(FieldValueType.stringField);
field.setLength(40);
fields.add(field);
oTable.setDataFields(fields);
oTable.setConnectionInfo(oConnectionInfo);
rcd.getDatabaseController().addTable(oTable, null);
This code succeeds, but it is not clear how to add that database field to a section. If I attempt to call the following:
FieldObject oFieldObject = new FieldObject();
oFieldObject.setDataSourceName(field.getFormulaForm());
oFieldObject.setFieldValueType(field.getType());
// Now add it to the section
oFieldObject.setLeft(3120);
oFieldObject.setTop(120);
oFieldObject.setWidth(1911);
oFieldObject.setHeight(226);
rcd.getReportDefController().getReportObjectController().add(oFieldObject, rcd.getReportDefController().getReportDefinition().getDetailArea().getSections().getSection(0), -1);
Then I get an error (which is not unexpected)
com.crystaldecisions.sdk.occa.report.lib.ReportDefControllerException: The field was not found.---- Error code:-2147213283 Error code name:invalidFieldObject
How do I add one of the table.SetDataFields() to my report to be displayed?
Are there any other pointers or suggestions you may have?
Thank you -
I downloaded the iOS7, lost all the custom ring tones that I had on my phone. the iTunes sync page says that they have all been selected but they don't show up in my phone? Help?
I had the same problem and was able to fix it. Go to your iTunes and click on the Tones folder on the left under library. Some of my ring tones had an exclamation mark next to it and those were the ones that did not sync. You have to click on those and find it in your computer. Once the exclamation mark is gone, go to Tones section of your device in iTunes, make sure you select the tones you want synced, and click apply. I hope that helps you!

I dowloaded ios5 for my iphone4, and when i finished the backup i lost all the music and all the videos i bought from the iTunes store. How can i get it back?
Backup do not contaiuns music or apps, you will either need to resync them from your itunes computer, or you can go to purchase history in itunes or app store app and go to purchase history and redownload them.

Remote Object - not able to get the returned value from java method
Hi ,
I am developing one sample flex aplication that connects to the java code and displays the returned value from the
java method in flex client. Here I am able to invoke the java method but not able to collect the returned value.
lastResult is giving null . I am able to see the sysout messages in server console.
I am using flex 3.2 and blazeds server and java 1.5
Here is the code what I have written.
<?xml version="1.0" encoding="utf-8"?><mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" backgroundColor="#FFFFFF" initialize="initApp()">
<mx:Script><![CDATA[
import mx.controls.Alert;
import mx.binding.utils.ChangeWatcher;
import mx.rpc.events.ResultEvent;
import mx.messaging.*;
import mx.messaging.channels.*
public function initApp():void {
var cs:ChannelSet = new ChannelSet();
var customChannel:Channel = new AMFChannel("my-amf", "http://localhost:8400/blazeds/messagebroker/amf"); cs.addChannel(customChannel);
remoteObj.channelSet = cs;
public function writeToConsole():void { remoteObj.writeToConsole(
"hello from Flash client");
var returnedVal:String = remoteObj.setName().lastResult; Alert.show(returnedVal);
//[Bindable]
// private var returnedVal:String;
]]>
</mx:Script>
<mx:RemoteObject id="remoteObj" destination="sro" />
<mx:Form width="437" height="281">
<mx:FormItem>
</mx:FormItem>
<mx:Button label="Write To Server Console" click="writeToConsole()"/>
</mx:Form>
</mx:WindowedApplication>
Java code
public
public SimpleRemoteObject(){
super(); }
class SimpleRemoteObject {
public void writeToConsole(String msg) { System.out.println("SimpleRemoteObject.write: " + msg); }
public String setName(){ System.
out.println("Name changed in Java");
return "Name changed in Java";
And I have configured destination in remote-config.xml
<destination id="sro">
<properties>
<source>SimpleRemoteObject</source>
<scope>application</scope>
</properties>
</destination>
Please help me .You are not able to get the returned value because if you see the Remote object help you will realise you have to use result="resultfn()" and fault = "faultfn()"
In this you define what you wish to do.
More importantly in the remote object you need to define which method you wish to call using the method class like this
<mx:RemoteObject id="remoteObj" destination="sro" result="r1" fault="f1" >
<Method name="javaMethodName" result="r2" fault="f2"/>
<mx:RemoteObject>
r2 is the function where you get the result back from java and can use it to send the alert. -

I am trying to use a website that requires that my computer have the latest version of Java, which I have updated and installed Java 7 Update 51 (64-bit), however Firefox does not recognize that I even have Java on my computer. My computer is 64-bit
When I run "Verify Java Version" it show nothing is installed... but it is, I know that for a fact because it shows in my "Control Panel/Programs/Programs and Features".
When I go back to the Java Download page, the following message is visible:
"We have detected you may be viewing this page in a 32-bit browser. If you use 32-bit and 64-bit browsers interchangeably, you will need to install both 32-bit and 64-bit Java in order to have the Java plug-in for both browsers."
My question is this:
Is there a way to change my Firefox browser from 32-bit to 64-bit.... because it appears that this is way Java is not functioning properly?Firefox needs 32-bit plugins, so you'll need to install 32-bit Java for Firefox.
No, you can't change Firefox from 32-bt to 64-bit. There is a Nightly 64-bit version (alpha) of Firefox, but it is used only to test for regressions until development is resumed. -
Background:
I have had this problem for several months, now. This problem began when an update came for Java on the Firefox Plugin-check. I promptly installed the new Java update. But the Firefox update wouldn't register that I downloaded it, even after I refreshed the page. So, I got rid of the old Java, and downloaded the new Java again. When the page continued to display the same message it had before, I downloaded it a few more times. Finally, Firefox stopped saying that I was out of date. Then a few weeks later maybe, I check Firefox Plugin, and on the page it says that I am outdated in Java. So I downloaded Java again. But Java was still in the list, with red and said that it needed to be updated. I restarted the computer. Then, I restarted Mozilla Firefox with no add-ons. When Java still appeared that it needed to be updated, I gave up and didn't do a thing more about it.
Problem:
Today I decided to check my plugins. Java was not in update the list, and at the top a banner stated, "Missing JAVA? For your safety, Firefox has disabled your outdated version of Java. Please upgrade to the latest version." I clicked "upgrade to the latest version" and was led to the Java page. I clicked the download button. My cache stated that this was the (6) download of that same Java plugin (see background). I chose to re-download it anyways. But Firefox still insists that I have not downloaded it.
Question:
Do I need to go to the control panel of Java and change something? Do I need to fix some setting on Firefox? Should I disable Java altogether, delete all Java-related files on my computer, and start all over with Java? What should I do?Try using http://ninite.com/java/ninite.exe to install Java. Please note that even though you download it you have to double click it to get it to run and install.

How to open and validate the tif images via java?
Is it possible to open and validating the photoshop images via java. Kindly advise me.
Thanks for looking into this.
Maria PrabudassI have recently looked at athe code for Image Processor.
To avoid bailing on errors it uses two techniques.
1) It turns off all PS error reporting in addition to just turning off dialogs with: app.displayDialogs = DialogModes.NO; (it restores the original settings when exiting)
2) It uses the Javascript construct Try.....Catch around the basic body of the code so "any" error will not abort the script but just jump to the "Catch" code.
Hope that is useful -

I cant seem to download and install the latest iphone software update. I have tried since the release and have been unsuccessful on more than 7 occasions and lost all the data on the process. Anyone have that problem an how do I fix this problem?
Hi
Thanks but I have tried doing the above - when I said 7 times I was modest, its more like 15 times.
And I am referring to the 5.1 software update. I dont have wifi so I guess I will have to try that seeing that my husband also has the same problem - he has also tried downloading several times. It always times out en says that the connection is lost but yet there are always an internet connection and a decent signal once it stopped. Think it said error 32052 or something!
I am disappointed because the update includes inprovement on the battery life - did you guys notice any difference? -
How can i use or embed the ' C' language in java
thanks a lot friends for your suggestion on using 'c' language to implement the control of the keyboard ie. to prevent a key stroke of : ctrl+alt+delete keys from closing a running java application. i was advised that it won't be possible to implement this with java language, the use of 'C' language was suggested. i then wish to ask the following:
1. how can i use 'C'language in a java program and be able to compile to program so that the resultant program can help me prevent the closing of my java-application when the user of the application presses the following keys : ctrl+alt+delete. i don't even know the c language at all. how can i start and how can i combine the resultant code with java.
2. i'm thinking of creating an application that retrieves information from a database, like microsoft sql or oracle, and displays the resultant data from a table, say STUDENT TABLE, in a java application using the JTable class. i don't even know how to use this JTable but i've seen it used and know it will suit what i have in mind.
3. how can i make the table dynamic, ie. how can i make the table to immediately register / show the result of an update to the 'STUDENT' table in the database.
4. THANKS FOR YOUR HELP IN ADVANCE. i will most appreciate it if you can give me a sample code or a site where i download one. once again thanks.Good luck disabling Ctrl+Alt+Del! I've read quite a bit about it, and at least on Windows 2000 (not sure about NT) or higher, disabling it is next to impossible. Problem is CAD is a system command, and the OS doesn't even send the keys to the active program. Ctrl+Alt+Del is handled by the GINA (Graphical Identification and Authentication) DLL installed on the system. You'll have to write and export the functions you need and change the GINA DLL used by the system to your own. Bear in mind that any small mistake in the dll can cause you to lose access to your computer if you haven't taken precautions!
On Windows 95/98, disabling Ctrl+Alt+Del is fairly easy as you just have to write some simple native code to fool the system that a password protected screensaver is running.
I've provided a link regarding winlogon and GINA here, but you've been forewarned!
