Dynamic generate JNLP from JSP ?

Hello,
I tried to generate JNLP from JSP, but it just show the Opem/Save diakog and cannot startup the Web Start.
I am using Tomcat-5.5.12 in WinXP + JDK1.5
How can I dynamically generate JNLP ?

It will range from easy to rather difficult, depending on how hard you try...
If you want to do the bare minimum it will require you to code up some JSPs with scriptlets, declarations, expressions, and <jsp:xxx ...> tags, have some server turn them into a servlet for you, and then determine how things like
<%@ page isELIgnored="false" %> are handled. Things like:
<jsp:useBean ...> <jsp:setProperty ... > should be rather easy to translate using introspection on the beans they refer to. But <jsp:import ...> and the likes may be more difficult.
Any normal html code is just wrapped inside a out.println(...) statement. Scriptlets should have the <% %> stripped and coppied to the output. Expressions should have their <%= %> stripped and be added to the surrounding out.println...
for example:
<a href="<%=thePage%>">
should become:
out.println("<a href=\""+thePage+"\">");
All the content should be added to a _jspservice method. Then, things between <%! %> should be coppied to source file as methods.
Complications come when people start to use custom tags. You will have to learn how to create a PageContext that will be available to the jsp service method.
You should also look up the JSP/Servlet spec to see how this stuff should be done.
It is a whole nuther can o worms if the resulting JSP is expected to compile without a server...</a>

Including dynamically generated pages in jsp

          Hello All, Scenario is like this, i am creating the dynamic htmls pages, in the
          servlets and after creating the htmls pages in the servlets , the control passes
          to the jsp page, where i am including the html page that is created at the servlets,
          its works fine, but some time it shows me null exception at the jsp page, i.e
          it won't find the htmls pages, even they are created b'fore. I am using weblogic
          server 6.1 with sp3. Can anybody know what is the reason.


After you have generated checkbox by jsp, you have to generate JavaScript for the checkboxes.
<%
// assume I have found I need to generate 5 checkboxes with jsp
int chkboxCount = 5;
String user = request.getParameter("user");
boolean showUser = false;
if (user!=null && user.trim().length()>0){
showUser = true;
%>
<script lang="JavaScript">
var chkcount = <%=chkboxCount%>;
for (int i=0; i<chkcount; i++)
     alert(i);
<%
if (showUser)
%>
    alert("hello <%=user%>");
<%
%>
</script>It is difficult to trace though.

WL10 generated servlets from jsp pages

hi!
I'm looking for .java servlet files automatically generated from JSP (Weblogic 10). Do anybony know where can I find this files?
Thanks in advace,
Bartek

Well, Servlet and JSP both are server side technologies and both can be used in web applications. You can write web pages using both servlet and JSP. In fact, your JSP pages are converted to Servlet by container while serving requests. However, writing a JSP page is relatively easier and requires minimal Java knowledge.
When you will develop real world java based web applications you will find that you are writing more JSP pages than servlet.
In a typical MVC (Model View Controller) architecture a single servlet is used as controller and JSP pages are used to generate web content.

What is the best way to delete dynamically-generated symbols from another symbol?

in the onClick handler for 1 symbol, I have:
var sandwhichQty1 = sym.createChildSymbol("sandQty1", "Stage");
another symbol inside sandQty1 has the onClick method:
this.deleteSymbol();
which works fine, deleting sandQty1. I'd like to delete it, and others, from another button, in the circumstance where users don't close them this way.
I notice that id and class are dynamically assigned to the child symbol, which makes it hard for me.
any ideas?

Hi, I did it in this way, and functions well; maybe this is not the best way, but worked for me. Obviously this code is based on the elainafineell's correct solution.
This is my scenario:
In a Trigger @ xxxxms there is that:
var i = 1;
$.each(results, function(index, element)
     var s = sym.createChildSymbol("mySymbol", "someContainer");
     // some code here
     // Creating the variable that save my new instance of mySymbol
     sym.setVariable("var_id"+i, s);
     i++;
// a global var, take care with the name
numOfInstances = i;
Then, in a click action of some button, symbol, anything that support an action, I code this:
sym.eraseSymInstance();
And, in the creationComplete, I code the function like this:
sym.eraseSymInstance = function()
          for(var i = 1; i <= numOfInstances; i++)
                         var s = sym.getVariable("var_id"+i);
                         s.deleteSymbol();
For me function well.
I hope this can be usefull for somebody else.

HTML from JSP

Hi all,
I got a problom,
How can i get the output of a JSP page into a java class?.That is,The original JSP page sends the generated HTML to the browser.What i need is that generated HTML into a java class.
Suppose i got an Email class ,
String myContent = -------
Email.setContent(mycontent);
The string myContent should be the dynamically generated HTML from a JSP page.
that is,
String myContent = output from CustInfo.jsp.
How to achieve this?.

>
String myContent = output from CustInfo.jsp.
How to achieve this?.Open a URLConnection (or HttpURLConnection) to CustInfo.jsp,
use the getInputStream() method to get a reference to the input stream for the jsp,
read this stream (which will be the HTML for CustInfo.jsp) into the String.

Dynamically generating the jnlp file

Hi Experts,
Im working on a project in which we launch the Eclipse RCP from the web UI (thin client).
I want to dynamically generate the jnlp file cause I want to pass the session of the user from the web client to RCP.
So for this i have thought of having a variable let say sessionID ,which will take value of the session
sum thing like this...
<application-desc main-class="com.rcp.core.HelloWorld">
<property name="sessionID" value="$$userSessionId"/>
</application-desc>
But im not able to figure out how i will populate the sessionID variable.
which class should be responsible for doing this?
whether that class will be in the RCP code or in the Web code...i guess it is in the web code?
Please if u can clarify these doubts then it will be great.
Thanks
ved

usually you would use jsp or a servlet to generate the jnlp file.
If you extend the JnlpDownloadServlet (found in the sample directory in the JDK) you can generate the session id.

How to generate Word document from JSP ?

Hi,
I want to generate Word documnet from JSP. I am using Neva objects to generate Word document. Now my problem is Word doc generation code works alright as a Java application but when I place that piece of code in a JSP bean it throws an exception. The reason seems to be unavailibility of DLLs and other files of Neva in Tomcat environment. I do not want to use other complex packages like JIntegra, I would prefer any freeware solution. There is not much info. about Word document generation on POI project in Jakarta site.
Could anyone suggest way out ? Any Java examples doing the same would be of great help.
Thanks,
Akash

Hi Saurabh,
Thanks for the reply.
I have tried that too. Problem with that solution is that if you have used CSS in your JSP code MS word does not understand it and generates word doc which is not the same as HTML which JSP otherwise would have generated.

Dynamically generate JSF Source code in a JSP

Hi,
I have a JSP and instead of writing the JSF source Code like:
<h:inputText
styleClass="entryInput"
id="textNumberOfServerMachinesInput"
value="#{DataAccess.value}"
valueChangeListener="#{InputValueChanged.processValueChange}">
</h:inputText>
manually in the jsp I want the JSF source code to be added dynamically to the jsp.
So what I want is including a tag in the jsp and this tag generates JSF source code like seen above.
This source code should then be treated just the way it would be if I had written it manually in the JSP. This means that the dynamically generated JSF code must be interpreted and all Listeners and Beans work just fine.
How can I make this???

Hi,
I have a smiliar problem:
JSP:
<h:panelGrid binding="#{fileUploadGrid.panelGrid}">
   <%-- emty in jsp --%>
</h:panelGrid>The panel should be populated with items the backing bean creates in source code:
FileUploadGrid.java
public void setUploadFieldNumber(int uploadFieldNumber) {
    this.uploadFieldNumber = uploadFieldNumber;
    this.refresh();
private void refresh() {
    if (this.panelGrid == null)
      this.createPanelGrid();
    List children = this.panelGrid.getChildren();
    children.clear();
    for (int i = 0; i < this.uploadFieldNumber; i++) {
      HtmlOutputText out = new HtmlOutputText();
      out.setTitle("Image " + i);
      out.setRendered(true);
      HtmlInputText in = new HtmlInputText();
      children.add(out);
      children.add(in);
private void createPanelGrid() {
    this.panelGrid = new HtmlPanelGrid();
    this.panelGrid.setColumns(2);
    this.panelGrid.setCellpadding("1");
    this.panelGrid.setBorder(1);
    this.panelGrid.setWidth("50%");
    this.panelGrid.setRendered(this.isRendered());
public void setPanelGrid(HtmlPanelGrid panelGrid) {
    this.panelGrid = panelGrid;
public HtmlPanelGrid getPanelGrid() {
    return this.panelGrid;
}The backing bean is initialized in faces-config.xml:
<managed-bean>
<managed-bean-name>fileUploadGrid</managed-bean-name>
<managed-bean-class>org.smi.pte.isf.FileUploadGrid</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property>
    <property-name>rendered</property-name>
    <value>true</value>
</managed-property>
<managed-property>
     <property-name>uploadFieldNumber</property-name>
     <value>6</value>
</managed-property>
</managed-bean>The problem is: although the debug output of the faces framework (I use it along with Tomcat) shows that the in- and output fields are added correctly to the panel, the page remains empty at display.
Thanks in advance for any help.

When someone other than myself downloads an image from my web album, a dynamically generated file name replaces the original file name. How I can prevent the original file name being replaced during the downloading process?

When someone other than myself downloads an image from my web album, a dynamically generated file name replaces the original file name. How I can prevent the file name being changed during this downloading process?

Hi Glenyse,
Here are my steps.
1. I upload multiple image (jpg) files onto my photo album.
2. I select the "sharing" by email option for this album.
3. I enter the recipient's email address.
4. The recipient receives my message and clicks on the link.
5. The recipient accesses my photo album and clicks on one of the images.
6. The image opens up to its own screen.
7. The recipient selects the "download" and then save file option.
Here is the part I do not understand. For some reason, during this "download" process, the original name which I have given to the file is replaced by different name. So I was hoping that someone knows how to prevent the file name from being changed during the "download and save" process.
Much appreciated if you can help me find a solution to this problem.
