Worst design and esp. documentation in Java???

I'm talking about javax.swing.undo.UndoableEdit
http://download.oracle.com/javase/7/docs/api/javax/swing/undo/UndoableEdit.html
From the javadoc:
... "UndoableEdit is designed to be used with the UndoManager. As UndoableEdits are generated by an UndoableEditListener they are typically added to the UndoManager." Why from an UndoableEditListener??? Couldn't this be from any source?
"If addEdit returns false replaceEdit is called on the new edit with the current edit passed in as the argument. This is the inverse of addEdit — if the new edit returns true from replaceEdit, the new edit replaces the current edit."
Huh? Am I the only one who had to read this 3 times to understand it?
"The UndoManager makes use of isSignificant to determine how many edits should be undone or redone. The UndoManager will undo or redo all insignificant edits (isSignificant returns false) between the current edit and the last or next significant edit. addEdit and replaceEdit can be used to treat multiple edits as a single edit, returning false from isSignificant allows for treating can be used to have many smaller edits undone or redone at once. Similar functionality can also be done using the addEdit method"
Does this not say the same thing twice? Also, there are grammatical problems around "allows for treating can be used to have many smaller edits undone or redone at once"
The designers admit that there are two ways to do the same thing with insignificant edits, but make no comments about why they made this design choice nor which is preferred under which set of circumstances. Why would you make more methods to support when they have the same functionality???
Where can I enter a bug / request for clarification for this?

OO Design and Java

I've been studying Java for a while now and am comfortable with the syntax and OO concepts. However, most of my programming experience is more traditional where you start off with an ER diagram and then develop the application to go on top of that. I have an idea for an application that I want to create using Java, but I'm having a hard time bringing the concepts of OO into a realistic design for a Java program. Can anybody out there point me to a site or resource that has an example of an OO design and what it looks like fleshed out in a Java program?
Thanks!

Entity relationship diagrams.
I associate them with database designs though.
To model in OO just try and think of everything as real world objects.
So for example if you would like to program a chessboard.
You would define a class which models the behaviour of the board which would include things like movePiece, setup board, PlayersTurn etc...
Now on that board you would have chess peieces each with thier own ability. You would have a class named abstract peiece which can not be instansiated just subclasses. Your subclass would be pawn, rock, knight etc.
Each has thier own ability. Object communicate by passing messages to one another.
Hope this helps somewhat

Problems with page and event paramters in java portlets

Hi there!
Following the documentation in "A primer on Portlet Parameters and events" and "Adding Parameters an Events to Portlets" I tried to develop two portlets (who will be at the same page), one showing some content of a repository (with possibilities to browse throw it) and another showing a sitemap of the repositories whole content, presenting links to the content's pages to be shown in the content portlet.
So I added:
1. a page parameter called pageMenuID to identify the current content page to be shown in the content portlet
2. an input parameter for content portlet called portletMenuID. This input parameter is mapped to the page parameter pageMenuID
3. an event for content portlet called changeContent with output parameter contentMenuID. When this event rises, "go to page" is set to the current page and the output parameter contentMenuID is mapped to the page parameter pageMenuID.
4. an event for sitemap portlet called changeContentFromSitemap with output parameter sitemapMenuID. When this event rises, "go to page" is set to the current page and the output parameter sitemapMenuID is mapped to the page parameter pageMenuID.
This is the code for some constants and a function to build the links in the content portlet, that I want to use:
// page parameter (shouldn't be used here)
private final static String pageParamMenuID = "pageMenuID";
// parameter names as given in providers.xml:
// portlet input parameter
private final static String inputParamMenuID = "portletMenuID";
// event name
private final static String eventName = EventUtils.eventName("changeContent");
// parameter name for event parameters
private final static String eventParamMenuID = EventUtils.eventParameter("contentMenuID");
String getEventUrl( PortletRenderRequest portletRequest, long menuID) {
NameValuePair[] eventParams = new NameValuePair[2];
eventParams[0] = new NameValuePair(eventName,"");
eventParams[1] = new NameValuePair(eventParamMenuID, "" + menuID);
try {
return PortletRendererUtil.constructLink(portletRequest, portletRequest.getRenderContext().getEventURL(),
eventParams,
true,
true);
} catch (Exception e) {
return "null";
This is the analog code from the sitemap portlet:
// page parameter defined on "edit page mode" (shouldn't be used here)
private final static String pageParamMenuID = "pageMenuID";
// parameter names as given in providers.xml:
// event name
private final static String eventName = EventUtils.eventName("changeContentFromSitemap");
// parameter name for event parameters
private final static String eventParamMenuID = EventUtils.eventParameter("sitemapMenuID");
String getEventUrl( PortletRenderRequest portletRequest, long menuID) {
NameValuePair[] eventParams = new NameValuePair[2];
eventParams[0] = new NameValuePair(eventName,"");
eventParams[1] = new NameValuePair(eventParamMenuID, "" + menuID);
try {
return PortletRendererUtil.constructLink(portletRequest, portletRequest.getRenderContext().getEventURL(),
eventParams,
true,
true);
} catch (Exception e) {
return "null";
But what actually happens is nothing. I also tried to construct the links with EventUtil.constructEventLink() with the same result. Checking the produced html-code in the browser shows that the same URLs are produced. So I'm of the opinion, that proper event links are created.
After checking the sent and received request parameters I came to the conclusion, that the event output parameters are never mapped to the page input paramters, as they should. So I changed the code to the following:
// page parameter (shouldn't be used here)
private final static String pageParamMenuID = "pageMenuID";
// parameter names as given in providers.xml:
// event name
private final static String eventName = EventUtils.eventName("changeContentFromSitemap");
// parameter name for event parameters
private final static String eventParamMenuID = EventUtils.eventParameter("sitemapMenuID");
String getEventUrl( PortletRenderRequest portletRequest, long menuID) {
NameValuePair[] eventParams = new NameValuePair[1];
eventParams[1] = new NameValuePair(pageParamMenuID, "" + menuID); <-- Note that the page parameter and not the event output parameter is used here -->
try {
return PortletRendererUtil.constructLink(portletRequest, portletRequest.getRenderContext().getEventURL(),
eventParams,
true,
true);
} catch (Exception e) {
return "null";
Now everything works fine, including addition of persistent private portlet parameters and further input/page/event parameters as well as working with a third portlet with performs a search (and presents the search results as links which change the content in content portlet).
But this is actually NOT the way it should work: The names of the page parameters are hard-coded in the portlets, so the roles of page designer and portlet developer are not separated in the way it is presented in the documentation. I coulnd't find a way to map the event output parameters to the page parameters to work this out.
Now I wonder whether there's some known bug in PDK or perhaps a mistake in the documentation or wether I'm just missing doing the right things. I've already read some postings in this forum concerning this problem (for example how to change the query??? but I think I've done all the things that are suggested there (checked the entries in provider.xml and the proper mapping of page parameters, public (input) portlet parameters and event output parameters, also the way I read the received request parameters and build the links)
Has anybody an idea what's wrong here?
Best regards
Torsten

Hi Amjad,
thank you very much for time and effort you spent on helping me solving this problem.
Unfortunately, I think I already tried what you suggest in your answer, but without success. From my experience, the following two calls:
1.
<%!
private static String eventName = "changeContent"
private static String eventParamID = "menuID"
String getEventUrl(PortalRenderRequest prr, long menuID) {
NameValuePair[] eventParams = new NameValuePair[1];
// no addition of eventName in the array
eventParams[0] = new NameValuePair(eventParamID, "" + menuID);
return EventUtils.constructEventLink(prr, eventName, eventParams, true, true);
%>
<a href="<%= getEventUrl(portletRequest, 1234) %>">some link for ID 1234</a>
2.
<%!
private static String eventName = EventUtils.eventName("changeContent");
private static String eventParamID = EventUtils.eventParameter("menuID");
String getEventUrl(PortalRenderRequest prr, long menuID) {
NameValuePair[] eventParams = new NameValuePair[2];
eventParams[0] = new NameValuePair(eventParamID, "" + menuID);
eventParams[0] = new NameValuePair(eventName,"");
return PortletRendererUtil.constructLink(prr, prr.getRenderContext().getEventURL(), eventParams, true, true);
%>
<a href="<%= getEventUrl(portletRequest, 1234) %>">some link for ID 1234</a>
produce identical links. I took the second way because it is easer to add private portlet parameters to the link: just as additional NameValuePairs in the eventParam- Array (name constructed with HttpPortletRendererUtil.portletParameter()), instead of constructing the link "by hand" as mentioned in the javadoc for constructEventLink(). I have to add these private portlet parameters here because when an event from a private parameters owning portlet is fired, the private parameters are lost (in difference to when an event from ANOTHER portlet is sent).
So I think, when you also look closely to the code snippet I added in the first posting, I made shure that I added the name of the event and not just the event parameters to the link.
I hope that I understood your answer right. Perhaps you have another idea what might be wrong. Thank you again,
best regards
Torsten

Switching between Design and JSP tabs add code?

I am new to SJSC and I am taking the time to go through all of the little odds & ends of the IDE.
I was looking at:
http://blogs.sun.com/roller/page/tor?entry=computing_html_on_the_fly
And I decided to try this.
When I add the following in the JSP tab:
<h:outputText binding="#{Page1.tableHtml}" id="outputText1"/>Save.
Then click on the Design tab, then go back to the JSP tab, I now have:
<h:outputText binding="#{Page1.tableHtml}" id="outputText1"/>
<h:outputText binding="#{Page1.outputText1}" id="outputText1"/>It's late here, but this doesn't make any sense, why would switching between Design and JSP tabs add code?
Thanks,

Document Autosave and Recovery - Documentation

We have done lot of search on Internet and Documentation and unable to find "Document Autosave and Recovery" - Documentation
We are looking for detailed workflow of this feature.
TIA
Any more information other then xi3-1_whats_new_en-1.pdf will be helpful
Document autosave and recovery
Web Intelligence now protects your work by automatically saving documents
before a server timeout, and at defined intervals while the document is open.

What exactly do you need to know ?
I would like to give User detailed workflow of Document Autosave and Recovery, Few things which i noted is that...
1. Once users session timeout users are prompted with alert for "Restore" is clicked it automatically logs back in without prompted for the password so there is another functionality and probably some security issues also.
2. How to enable and disable Autosave feature, right ...
3. How does it work with JAVA/HTML/Interactive viewer.
4. We have seen that in some scenario it saves report in another it does not saves report.
When you login into Infoview first time and edit webi report, you will be prompted with Auto Save dialog, explaining how it works.
Basicaly, webi report you're editing will be saved in your Favorites ~WebIntelligence folder, where it can be recovered.
Even though you are not timed out if users open two browser with same id "In ~WebIntelligence folder"' user see report. So can we assume that it still saves report even though users does not timeout.
So overall We need some detailed documentation from BO, Else i am tempted to create one with all my testing

How to design and implement an application that reads a string from the ...

How to design and implement an application that reads a string from the user and prints it one character per line???

This is so trivial that it barely deserves the words "design" or "application".
You can use java.util.Scanner to get user input from the command line.
You can use String.getChars to convert a String into an array of characters.
You can use a loop to get all the characters individually.
You can use System.out.println to print data on its own line.
Good luck on your homework.

Control Design and Simulation and DAQ

I'm learning Control Design and Simulations. I have some questions about it.
1. For System Identification use, we can find the transfer function/model of the system by feeding data measurement from the system. But, how long data do we need to be sufficent for Identification System to estimate the model? Until the get saturated value (steady state)? or any other intervals? What if the system is unstable? How will Identification System Toolkit estimate that case?
2. For connecting to hardware, we just connect the clock in the simulation loop to the hardware? And the simulation loop will simulate the blocks inside once it got the trigger/data from the DAQ? what about the step time and solver? Do they follow the timing from hardware? or they will run on their own supplied values/clock?if we use USB DAQ, we can't have any clock from it (as far as I know it's because USB connection is not that stable for clocking since it might be any jitters or delays.) So, how do we configure the timing parameter for USB DAQ?
3. There is possibility to convert model in transfer function to state space, how do we know the states inside that conversion?
Any helps would be great...
Thanks in advance...

Dear Chin ho,
After going through your questions I found some documentation which will be useful for you. But I you still have more questions, you can reply me any time.
1- About the data and amount of it I couldn't find any info but maybe you can use the new functions in LV version 2009 and find your answer.
Estimating States of Nonlinear Stochastic State-Space Models with Extended Kalman Filters
In previous versions of the LabVIEW Control Design and Simulation Module, you can use the Discrete Kalman Filter function and the Continuous Kalman Filter function to estimate the states of a linear discrete or linear continuous stochastic state-space model, respectively. In the LabVIEW 2009 Control Design and Simulation Module, you can use the Continuous Extended Kalman Filter function and the Discrete Extended Kalman Filter function to estimate the states of a nonlinear continuous or a nonlinear discrete stochastic state-space model, respectively.
The Continuous Extended Kalman Filter function and the Discrete Extended Kalman Filter function estimate model states of a partially observable plant based on noisy measurements. First, use the SIM Discrete Nonlinear Plant Model template VI or the SIM Continuous Nonlinear Plant Model template VI, located in the labview\templates\Control and Simulation directory, to define the system model. Then use the the Discrete Nonlinear Noisy Plant function or the Continuous Nonlinear Noisy Plant function to simulate the discrete or continuous nonlinear model, respectively, with the addition of noise. Finally, use the Continuous Extended Kalman Filter function or the Discrete Extended Kalman Filter function to estimate the states of your model.
The Continuous Extended Kalman Filter function and the Discrete Extended Kalman Filter function linearize the nonlinear system either by calculating a Jacobian matrix internally or by using an external Jacobian matrix that you define. Use the SIM Continuous Jacobians template VI or the SIM Discrete Jacobians template VI, located in the labview\templates\Control and Simulation directory, to define an external Jacobian matrix.
Refer to the LabVIEW Control Design User Manual, accessible by navigating to the labview\manuals directory and opening CD_User_Manual.pdf, for more information about estimating the states of nonlinear stochastic state-space models with extended Kalman filters.
2- I think that I found a pdf document about this part of your question which will be helpful. If you would like to give your email address, I can send it to you.
3- About this part you can check the help function in LabVIEW when you open the "CD Convert Transfer function To State-space" function in your front panel.
I pasted some info about the mathematic part below.
The LabVIEW Control Design and Simulation Module provides tools to study the dynamics of systems described by linear time-invariant (LTI) continuous and discrete models. You can create deterministic state-space, transfer function, and zero-pole-gain models. You also can create stochastic state-space models and the second-order statistics noise models. You can use these forms to describe both single-input single-output (SISO) and multiple-input multiple-output (MIMO) systems.
Continuous transfer function and zero-pole-gain models use the s variable to define time, whereas discrete transfer function and zero-pole-gain models use the z variable to define time. Continuous state-space models use the t variable to define time, whereas discrete state-space models use the k variable to define time.
Deterministic State-Space Model
Continuous
x(t) = Ax("t) + Bu(t)
y(t) = Cx(t) + Du(t)
Discrete
x(k + 1) = Ax(k) + Bu(k)
y(k) = Cx(k) + Du(k)
Stochastic State-Space Model
Continuous
x(t) = Ax(t) + Bu(t) + Gw(t)
y(t) = Cx(t) + Du(t) + Hw(t) + v(t)
Discrete
x(k + 1) = Ax(k) + Bu(k) + Gw(k)
y(k) = Cx(k) + Du(k) + Hw(k) + v(k)
Second-Order Statistics Noise Model
Q = E{w . wT} – E{w} . ET{w}
R = E{v . vT} – E{v} . ET{v}
N = E{w . vT} – E{w} . ET{v}
where
t is continuous time.
k is the model sampling time multiplied by the discrete time step, where the discrete time step equals 0, 1, 2, …
x is the model state vector.
u is the model input vector.
y is the model output vector.
w is the process noise vector.
v is the measurement noise vector.
A is an n × n state matrix of the given model.
B is an n × m input matrix of the given model.
C is an r × n output matrix of the given model.
D is an r × m direct transmission matrix of the given model.
n is the number of model states.
m is the number of model inputs.
r is the number of model outputs.
G is a matrix relating w to the model states.
H is a matrix relating w to the model outputs.
Q is the auto-covariance matrix of w.
R is the auto-covariance matrix of v.
N is the cross-covariance matrix between w and v.
E{} denotes the expected value or the mean of the enclosed term(s).

Advantages and Disadvantages of webdynpro JAVA over J2ee?

Hi,
Can anybody provide me the advantages and disadvantages of webdynpro java over the J2EE?
Regards,
Harish.

Hi,
Webdynpro is the SAP standard technology for developing business user intrefaces.
Webdynpro is like the frame work which follows the MVC Design pattern.
Webdynpro uses most of the UI developement as declarative approach , i.e. most of the code will generated by the framework. so it will reduce the developement efforts.
Adaptive RFC model to connect with SAP systems.
All these are advantages over than the J2ee.

Should I learn database design and development skills?

Hi everyone,
I am a junior Oracle with 3 years experience. I have got Oracle 10g and 11g OCP certifications.
I know how to install, configure,monitor and maintain databases, but I don't know hot to design and develop databases.
I know that employers demand of us more and more. Database design and development skills are the basic requirements.
Should I start to learn database design courses?
If yes, please recommend me the books(or Oracle Docs) of Getting Started.
Thank you very much

Google "data normalization" and study up on 1st, 2d, and 3d Normal Form.
Go through the Oracle docs and get very familiar with the different data type (varchar, number, date, etc)
Read the Tom Kyte Books.
Programmers keep wanting to re-invent what the database already does, and treat the database as a data dump. As a result, I'd focus on analysis and design issues before approaching books on programming technology. (and I was an applications programmer/analyst for about 15 years before transitioning to DBA)

Management VLAN Design and Implementation

Greetings, friends. I'm having trouble getting a clear picture of how a management VLAN ought to look. I just installed a Catalyst 6509-E as my core switch, and as soon as they arrive I'm going to be replacing all of our other (HP) switches with Catalyst 3560X switches. I understand the reasoning behind segregating traffic, not using VLAN1, etc., but I've never actually implemented a management VLAN--I've always just accessed the switches via the IPs assigned to them where all the client traffic flows (not VLAN1, by the way).
Is "management VLAN" simply what we as humans call a VLAN we dedicate to management activities, or is there something official in these switches to designate a "management VLAN?"
Is it best practice to include SNMP, netflow, syslog, and NTP as "management" traffic?
There's a lot of documentation talking -about- management and management VLANs, but unless I'm blind or not looking hard enough I can't seem to find any implementation whitepapers or best practices whitepapers that demonstrate setting one up on a campus LAN. Are you able to point me in the right direction to find such documentation? Is it perhaps buried in a manual somewhere that isn't explicitly labeled "Management VLAN Design and Implementation" or somesuch?
What is the best practice for accessing the management VLAN? Inter-VLAN routing + ACLs? Multi-homed PCs or servers? Additional PCs to be used as access stations?
Thank you for your wisdom, experience, and advice!
Kevin

1. Yes, you may want to keep this traffic separate of the other traffic limiting device management access to just this vlan, as this prevents eavesdropping.
2. Indeed all other housekeeping goes via this VLAN altough you could limit it to the interactive or session traffic.
3. On a campus you could think of one big VLAN spanning the campus, one a multi-site environment or where you use L3 to go to you datacenters you probably need multiple management lan's. I've seen implementations where the management traffic was kept separate and even didn't use the routing protocol in use. The whole management lan was statically routed and would work even if OSPF or BGP was down.
4. I feel a situation where the people providing support are connected on the lan giving access to the devices is probably best. A dual homed pc is a good solution I think, other customer feel the management lan should be treated as a DMZ accessible via a firewall, but the hardcore customer insist on a second pc connected to the management lan.
Points to consider are as always,
Find the single point of failure. Any device, L2 L3 firewall that could cut off management from accessing a part of the network.
Find the right balance between security, costs, easy of access for the business your in.
Cheers,
Michel

Where is the download for Oracle Weblogic Portal and current documentation?

The web page for Oracle Weblogic Portal has a download link, but nothing happens when I click it:
http://www.oracle.com/technetwork/middleware/weblogic-portal/downloads/index.html
I've downloaded the documentation

which is supposed to be for version 10.3, but the dates on the documents are all from 2008. I don't see anything indicating support for JSR 286 in those documents.
Are there more up-to-date documents for the latest version of Oracle WL Portal?
Thanks.

Hi Dean
Looks like that site is down. On Firefox, I checked in Error Console window and it shows some java script error like acceptAgreement is not found etc. This link did worked earlier. I hope they fix it asap. Same problem with IE browser also (java script error).
Coming to documentation, based on your link, I hope you are using 10.3.2 docs. I clicked on View Library and then select Portlet Development -> Java Portlets link and got this link: This link does cover JSR 286 stuff. For more indepth JSR 286, you can google and get more details.
