View Replies View RelatedI am trying to display a list fetched from DB in a JSP.
My servlet mapping is:
<servlet>
<description></description>
<display-name>DocumentsServlet</display-name>
<servlet-name>DocumentsServlet</servlet-name>
<servlet-class>com.xyz.servlet.DocumentsServlet</servlet-class>
[Code] ...
The code in the servlet is:
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
List<Doc> docs = null;
Connection con = null;
[Code] ....
The code in JSP is:
<%
List<WWDoc> completedDocsList = (List)request.getAttribute("completedDocs");
System.out.println("In JSP == "+completedDocsList.size());
%>
The request is not coming back to the JSP page.
If I change the servlet and have "request.getRequestDispatcher("/pages/ViewCompletedWWDocs.jsp").forward(request, response);" un commented, I get exception "java.lang.IllegalStateException: Cannot forward a response that is already committed".

I need to fetch the values inside the tag/node of an XML file.
The xml.file looks like this,
<numeric_values>
<data cc="100" ln="58">2291</data>
<data cc="100" ln="59">2291</data>
<data cc="105" ln="58">2389</data>
<data cc="105" ln="59">2389</data>
<data cc="110" ln="59">1</data>
<data cc="110" ln="57">1</data>
[Code]...
I need the value of cc and ln.
For example the first line contains cc = 100 and i need to fetch 100 and ln = 58 and i need the value 58.
I am generating textfields dynamically using JSTL forEach. Here is the code ..
<c:forEach var="underlyingTickers" items="${underlyingTickersList}" >
<tr>
<td ><input name="underlyingTickers" type="text" id = "underlyingTickers" value="<c:out value='${underlyingTickers}' />">
</td>
</tr>
</c:forEach>
If there are 4 values in underlyingTickersList A, B C, D and E ... I am getting those values correctly displayed in each text field.
However if I submit the form with all these value how can I get it in the bean? I guess I need to have dynamic id or name for each text field. How can generate it?
Note** I dont have Struts framework.. I am using request.getParameter to fetch the values and set into the bean variable.
I have code which query value from database, the use case is the user can enter value as 1,01,11 in database but when the user enter value in xml file he can only enter 11,01,12 in database there is two columns lets say column test1=1 and test2=2 combination of this is 12, which is the value the use will enter in xml, but sometime the use can enter test1=04 than column test2=00 how can i approach this
I got table called card with column crdind,crdpos1,cardpos2 as primary key. The user can enter value as
crdind=1
crdpos1=5
crdpos2=3
inactivedate=2013-05-24
activedate=null
another row
crdind=1
crdpos1=5
crdpos2=5
inactivedate=2013-05-24
activedate=null
another row
crdind=6
crdpos1=02
crdpos2=00
inactivedate=2013-05-24
activedate=null
The rule say if you enter one number in crdpos1 eg 2 than you must enter value in crdpos2 it can be any number 1-9 but if you enter 00-09 in crdpos1 than crdpos2 is 00
The challenge I have is to query this value after they been enter. I have xml file which got field crdpos the use enter 15 which is the combination of column crdpos1=1 and crdpos2=5 ... How can I split the value crdpos and got and able to query in database in two separate column ....
we had a requirement to display a combobox which is filled with some values on the webpage when somebody checks the checkbox which is present on the webpage.
The approach we have taken is ajax. how we did this is, when somebody checks the checkbox on the webpage we are initiating the ajax call requesting a servlet. this servlet pulls the data from the database, places the data in the request and forwards the request to a jsp. In that jsp i am writing simple html combobox and populating the values in the combobox from the request using JSTL and this jsp will be sent as response to ajax call. The ajax gets the html as responce which contains a combobox and i am just placing that html ( the complete response) in a div which is next to checkbox.
In this approach there is lot of pain. if i have to display 10 html components dynamically based on some condition then i have to have 10 jsp's one for each component. I always feel this is a wrong way of doing things. what is the best approach to deal with the dynamic stuff on webpages.
I want to develop a dynamic webpage (using JSP & tomcat hosted on windows server) which will connect to unix server and on button "Show Files" click on dynamic webpage it should display all the files present in the unix server.
The button click should display the files which i can see when i run "ls -ltr" in unix server home directory.
I am trying out jsp and servlets now for the first time. I have to insert two data, car code and car name into a mysql table. I got those details using jsp but if I use form, it redirects to another page for insertion. I want the data to be inserted and still remain in same jsp page. I am thinking of using onClick from javascript but as I googled this many places have said it is a bad idea to use jsp inside javascript. If so how can we insert data to mysql table without redirecting to another page?
View Replies View RelatedHow can I get id from db table for each column values with java or oracle query? I did get before each column content from file and now i need get the id of this column values from db. I read csv files from folder and then load the data from these files into subfolder, and here with line li = line.split(","); I get the values that i have in csv file and split them and become in li the value name, and then in else block i create a P objekt where i set this values from csv files, and with [I]p.setLid(li); I set the value for all valuenames, and then get these valuenames in separate column with other content from this csv.
My question is, i need to do this with db, and write these csv file values to the table in db (it will be done with another java class), what i need, that to write the ids of these values into the table in db, instead of valuename, and while there is no ids for valuenames in csv files, i need to get the id from the table in db where these are already listed with sequences, and i don't know how can i write in data table the id of this valuenames and other content, this data table should contain the ids of valuenames timestamp values and the ids of the csv files name, i don't know how to do this with the ids, i must get the ids from the db table and then set these on [I]p.setLid(li); where i set early the valuenames, instead of valuenames i should set ids, that will set ids automatically for all these valuenames.
Java Code:
try {
while ((line = br.readLine()) != null) {
if (lc == 0) {
li = line.split(",");
[Code] ....
with
Java Code : li = line.split(","); mh_sh_highlight_all('java');
I got the values that then will be given to [I]p.setLid(li); and iterate, but now i want to get id from the table in db where this values stored with id instead of this column values, how can i do it?

View Replies View RelatedHow to pass the value of a field in a database from one view to another. I currently have a list of members drawn from a database.
The members view is a list of members. From the list the user clicks view button to view a particular member. This is achieved by using a inputHidden tag with the value of the list of members in a data table.
<h:dataTable value="#{controllerBean.listAllMembers()}" var="mem">
<h:form id="inputForm">
<h:inputHidden id="idToken" value="#{mem.id}" />
in the RequestScoped bean I am able to use FacesContext to extract the value of idToken from the requestParameters and create the view for the particular member.
One field in the member view I would like to toggle - "Y" to "N" or vice versa via a commandButton. The issue is I can find no way of passing this single value back to the bean as is.
<td>Active:</td>
<td><h:outputText value="#{controllerBean.member.active}" /></td>
<td>
<h:outputLabel value="To change toggle active button below" />
<h:inputHidden id="actToken" value="#{controllerBean.active}"/>
</td>
//further down the view
<h:commandButton style="float: right" value="Toggle Active" action="#{controllerBean.toggleActive()}"/>
The issue is the value is displayed within the output text - how to pass the value into the inputHidden value.
I am using primeface in this project. I have a database with orders, order details and customers. The index page displays the order details and I click on one of the orders I want the customer details of that order to be displayed. But right now when I click on an order the dialog box that appears is empty. I'm not sure if the problem is with the jsf for the customer class.
here is the jsf page:
<p:dataTable value="#{orderDetailsBean.list}" var="anOrder"
paginator="true" rows="10"
paginatorTemplate="{CurrentPageReport} {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"
