Hidde database values when looping through jsp:useBean collection

<jsp:useBean id="categories" scope="request" class="java.util.Collection"/>
<c:forEach var="dto" items="${categories}">
<td width="375px" class="categoryContentTD">${dto.categoryName}</td>
<td width="75px" class="categoryContentTD">${dto.categoryStatus}</td>
<td width="75px" class="categoryContentTDEdit" align="center">
edit
</td>
</c:forEach>
When I view source I can see the values in my database. Is there anyway to hide these from view source?

You can use an alias for the key values. For example, if you have a list of personIDs for your list as follows:
325244,32156,51255 that you dont want on the displayed page, you can store those numbers in a two dimentional array in the user's session scope back on the server as follows:
1 325244
2 32156
3 51255
Now, you send 1,2,3 to the JSP page. When you get back 1,2, or 3, you use that two dimentional array to convert the number back to personID. Now you have personID you can use in your datbase sql statements.
You can use a simliar array if you dont want to display the database table column names in the JSP page (so user's dont know info about your database schema).

How can i load A gui JTable bean through jsp:useBean tag in a jsp page

Hi,
i am chiranjit , i am in a jsp project . i am desparately looking a solution for below stated problem:
i want to make a jsp page for master entry , that why i want to load a GUI Java bean in my jsp page.This GUI Bean contaning a JTable in which allow grid type data entry in the jsp page. But i am unable load that bean in the jsp page through jsp:useBean tag in my page.So if you have any solution then send in the forum as early as possible.
Thank you
chiranjit

No can do. JSPs can only output plain HTML (and javascript...) They are not used like normal Java classes.
If you need a complex GUI then you might use an Applet instead. If you want to use a JSP then you are stuck using normal HTML components, like <table> <form...> <input type="text"> etc...

Problem when loop through a list within CollectionModel

In my bean, I have these codes to define a node.
Map<String, Object> node = new HashMap<String, Object>();
node.put("Nodeid", nodeid);
List theColors = new ArrayList();
node.put("Colors", colors);
node.put("Type", type);
node.put("Desc", desc);
Then, a list of these nodes are converted to CollectionModel using ModelUtils.toCollectionModel(nodes);
In my jspx, I am able to loop through nodes, and get Type, Nodeid and Desc from the node to show on the screen.
I am trying to loop through the list of colors within the node to draw circles with different diameter.
<af:forEach var="theColor" items="#{node.Colors}" varStatus="vs">
<dvt:pointLocation pointX="50%" pointY="50%">
<dvt:marker id="mk2" scaleX="#{15-vs.index*2}" scaleY="#{15-vs.index*2}" shape="circle" fillColor="#{theColor}" />
</dvt:pointLocation>
</af:forEach>
But above code does not work.
Can someone help me? Any suggestions?
Thanks.

I want to call a javascript function inside a c:forEach loop.Nope sorry, won't work.
Java/JSP runs on the server. At the server end, any html/script code is just template text to output to an html file.
The server produces an html file, and sends it to the client.
Java stops running.
Java cannot call javascript, javascript can not call java. There is no direct communication.
Java code can produce javascript code to run on a page.
The only communication javascript has back with the server is if it makes a request (click a link, submit a button, Ajax call...)

Text is not being displayed in sync on a label when looping through a list -- how to fix?

I have a list of states (50 states). I loop through this list (in a winform app -- VS2012) and want to display the current state ID that is being processed in the loop in the text property of a label. I precede the label.Text = StateID line with
Application.DoEvents() but I am also (in Debug mode) writing the same text to the console. The console displays correctly, but there appears to be a lag in the label.Text property
List<string> StateList = new List<string> { "al", "ak", "az","ar","ca","co","ct","de","fl","ga",...};
foreach (string stateID in StateList)
Application.DoEvents();
lblStateID.Text = "State is " + stateID; //--there is a lag here
I vaguely recollect something about a NotifyPropertyChanged event. I know this is common in WPF, but is there something similar in winform? Or is there a way to make the desired text to be displayed in the label.Text property in synchronization
with the loop?

Thank you. This is way simpler than implementing the INotifyPropertyChanged Interface. Although, here is an article on the INotifyPropertyChanged Interface and event

How to get the database value without submitting the jsp page

Hi,
I have a form that has many fields (textbox/listbox). when user enter/change a value in the first textbox, I need to pass this value to the database to check whether it exist and get the other values to be displayed to other fields in that form (i cannot get the javascript value to be pass to jsp without reload/refresh/submit. But, I need to get the user entered value, so I thought of hidden popup, iframe, etc but not sure how I could apply and which best suit this case). If I submit the page then I can easily get the value thru 'request.getParameter("fieldname") but cannot use this because I cannot submit the page.
Pls help and possible provide me with the sample coding
Thanks

The best way for you is surely AJAX. But there is another way to stay compatible with older browsers:
Since the default method a browser supposed to get data is refresh, there is nothing unnatural in it. Browsers are optimized to refreshes, like cached images, etc..
So for these step-by-step things, you need to roll forward your data from page to page, and make the page to respond according the data it actually have. This can be easily achived with type="hidden" input fields in a form: the user will send you back all the data. Optionally you may show him the data you already have as visible text too.
A more generalised way to "pull" the data: you make a whole page you include every time you need an additional data. This page will receive 2 parameters from where you've included it. This 2 parameters are each indexed arrays with the datas you have to pull in (here the default value), and you need to push forward. Optionally there is a 3rd parameter, the url it have to return (as the form's action property).
And for them who now say that it would me more culture way to store this data in the session: Beware! Common mistake: Sessions are to store data about the user itself, not the datas for the next page! You never know what will be the next page! The user click some backward button and refresh button, and depending on your script, it may go stupid! Ok, not all the codes, but I've seen some. It's ok to store a sent file (fx. image) on the server, but always think the evil refresh and back buttons!

Updating a database value when you don't have the current value

I need to write a query that updates the amount of points a
user has, even though i don't know how many they have currently.
This is part of a referal program. When a user gets another user to
join, the original user gets 15 more points. The problem is I do
not want to write a query that finds how many points the original
user has because that seems wasteful. It should look something
like..
<cfquery datasource="users" name="givepoints">
Update users
set points = [whatever the current value is + 15]
where userlogin = form.referer
</cfquery>
That line that has the value in the brackets is where i am
confused. I don't know the current value so how can i add 15 to
it?

In some databases, oracle for example, the use of
cfqueryparam speeds up your queries. It also has the potential to
simplify your code in that it handles things like apostrophes, so
you don't have to.
On the other hand, if you want to cache your query, you can't
use cfqueryparam. Also, if you are using some sort of logic to
build an sql variable to use in your query, it takes a lot of
effort (more than I'm prepared to give) to use cfqueryparam.
Also, not every db supports it.
cfqueryparam has it's place, but that place is not
everywhere.

Set Page item value when paging through an sql query report

I have a report that includes a checkbox to indicate which rows a process is to be run on. I have a "Select All" button that sets a value to check all boxes in the report, and deselect button to turn that feature off. The page only renders one of the buttons at a time depanding on the value. If the "Select All" is turned on, I would like to set the value to "OFF" when a user goes to another page of the report.
For example:
A user enters the page and the report is rendered. The rows returned are greater than what is displayed. The paging options for the report are shown. 1-15 16-30 etc. It is currently showing the first 15 rows of the report.
The user clicks the select all button, and all checkboxes are now checked. Currently it will remain this way until the deselect button is clicked.
When the user clicks the report paging, I would like to set the value of the Select All item to off.
Does anyone know how to do this at this point?

Pass intersection values when drilling through by clicking on a value in a matrix

I have two SSRS reports. One is acting as a source report and the other as a target report.
Both reports give information about "Customer Contact".
My source report contains one matrix with the following attributes:
Columns: Contact type (Email, Phone, Desk)
Rows: Employee function (Administrative, Manager)
Measure: Contact quantity
The source report has two parameters on 'Contact type' and 'Employee function'
My target report contains one matrix with the following attributes:
Columns: Customer name
Rows: Employee name
Measure: Contact quantity
The target report has two parameters on 'Contact type' and 'Employee function'
I am using [Action] from the [Textbox property] of 'Contact Quantity' to go to my target report.
What i want to achieve is the following:
Lets say i select All for both parameters when running my source report.
I get all the Contact types against all the Employee functions.
Now the intersection between 'Email' and 'Manager' is 27.
When i click on the value 27 in the matrix i want to go to my target report and pass trough Email and Manager so filtering can take place based on the intersection i clicked on in the source report.
What it does now is just pass the full parameter value selected from the prompts in source report. I want to narrow it down.
Any help? Thanks!

Hello Qiuyun,
Thank you very much for your reply.
I have managed to get the drilltrough from source to target working correctly by passing the field value. I first got it to work on a small test data set and it works fine. However when i used this method on my production reports the performance became very
bad. My first drilltrough took about 30 seconds instead of 2 seconds when i was passing the full parameter values. The next drilltrough gives back an out of memory error after quite some time (20 minutes +).
One important thing to mention is that these reports run on an SSAS cube. I made the following changes to the setup to get the pass field value method working.
Initial setup: (Fast response)
1. I start of by creating a new report.
2. I select a the datasource (SSAS Cube) and i open the 'Query builder'.
3. I then drag the attributes i need from the cube to the query.
4. Afterwards i drag the attributes i want to use as parameters to the pane above the query and mark them as parameters. When finishing this step the parameters are automatically created in the design view (Report Data Pane) and within the data set of the
report. When running the report the available values for the parameter are displayed automatically.
5. Now i can run the report without having defined filters on the dataset. This setup performs very good but does not make it possible to pass trough field values.
New setup: (Very slow response)
1. I start of by creating a new report.
2. I select a the datasource (SSAS Cube) and i open the 'Query builder'.
3. I then drag the attributes i need from the cube to the query.
4. I DON'T drag any attributes to the above pane (Dimension, Hierarchy, Operator, Filter Expression, Parameter) to be marked as parameters, i just finish after dragging to the query pane.
5. Now i create my parameters manually in the design view (Report Data Pane).
6. If i want to populate the parameters i do this by defining a separate dataset (query) per parameter to populate the drop down box. Otherwise i manually enter a string.
7. I manually add the parameters to my dataset in the design view.
8. Last i add filters which indicate what fields need to be filterd based on which parameter value.
Any suggestions on how to get this working with acceptable performance?
Thanks in advance for your help.
(If you need screenshots to clarify the steps please let me know)
Kind regards,

Sy-subrc = 8 when looping through a table...

i am looping one table and reading other.
now sy-subr = 8,it is showing what can be the reason.
Thanks in advance.

Subject title improved

Hi,
If
sy-subrc = 4 No lines were read.
sy-subrc = 8 The search key was not fully qualified.
So u can add the logic for sy-subrc = 8 or u can change the logic as
if sy-subrc is initial.
else.
endif.

For installing JSTL, all you need are the jar files in the web-inf/lib directory.
- No entries in web.xml
- no tld files lying around
- no problems!
I think you may have a versioning problem here.
What version of Tomcat are you using?
With JSP1.2 (eg Tomcat 4), you should be using JSTL1.0. <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
With JSP2.0 (eg Tomcat 5), you should use JSTL1.1. <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
Note the difference in the URIs. - the second one includes a /jsp
Currently you are using the URI for JSTL1.0, but you look to have the tld from JSTL1.1. If you are using a JSP1.2 container, I don't think it could read this tld file, hence the error.
Try installing the correct version of JSTL, properly (ie as they tell you in the readme file) and it should all work.

Jsp:useBean : Missing value of String classed bean with 'session' scope

Hi!
I'd like to ask some help.
I have these two JSP pages:
1.jsp<jsp:useBean id="str" class="java.lang.String" scope="session"/>
<html>
<body>
<% str="hello"; %>
<a href="2.jsp">click</a>
</body>
</html>
2.jsp<jsp:useBean id="str" class="java.lang.String" scope="session"/>
<html>
<body>
<%=str%>
</body>
</html>When I open 1.jsp in my browser, then click on the link, the result is "nothing" (empty string). Why does the bean lose its value on the way?
I use a Tomcat 5.5.9 server.
Any help will be highly appreciated.

You have to think of several scopes when working with JSP. The first is the local scope: the method _jspService() where all the work of the JSP is done. This acts as a normal method and is where all the sciptlet code goes.
When you use jsp:useBean you are creating two references to a new String object. One in the local scope accessible through <%= str %> and the other in the session scope.
When you do <% str = "hello"; %> you are changing the local str variable to reference the String "hello" (this is equivalant to doing <% str = new String("hello"); %>). Only the local reference is changed, not the second reference in session.
If you want the change to take affect, then you will have to store the new value in session with the same name:
<% session.setAttribute("str", str); %>

Passing "Value Objects" from one JSP to next (2)

          Someone posted a response from BEA which has since disappeared, it was no different
          from what I was doing and it I still can't get it to store the information in
          the Value Object.
          I get values (true/false) from a Radio button on a FORM in a JSP, press a "Next
          Step" Button.
          I have a "Value Object" in JSP_1, which I use the setters to store various information
          obtained from the <FORM>. I then "jsp:forward" to JSP_2, set different information
          and then I "jsp:forward" to JSP_3 & so on. At the end of the JSP chain only the
          last setter is has the value "true", all the other values are false, despite all
          being "set" to "true".
          The "Value Object" is not storing the information set in previous JSPs. When I
          initially create the "value object" I use;
          <jsp:useBean id="myVO" class="uk.co.notify.valueobjects.MyVO" scope="request"
          />
          <jsp:setProperty name="myVO" property="*"/>
          In JSP_2 JSP999 I don't use <jsp:setProperty> I let the setter in the VO do
          it.
          I am using WebLogic 6.1 sp2 under Windows 2K Pro.
          Any pointers. Thanks.

Ok. here's the difference.
          Hitting submit is altogether a different "new" http request. It will send a
          new request from your browser to the server. Whereas, the jsp:forward is
          within the server itself.
          So the VO object whose scope is set to "request" will not retain its values
          between 2 http request.
          For such kind of parameter passing, you could very well store the info. in
          user's session object.
          I hope this helps.
