Using hyper-links in a jsp pages that are in a Session
Hi i am trying to include a hyper-links in my jsp pages that are in a Session, however when i use the links to navigate throughout the pages i get a java.lang.NullPointerException. The Session begins after the user has been validated i.e
String cid= request.getParameter("counsellorID")
session.setAttribute("counsellorID",cid);
All the pages included within the session have a session scope=session
; and they call the attributes that have been set when the session first begins i.e
String counsID= (String) (session.getAttribute("counsellorID"));
Any advice on this problem would be most appreciated!
Many Thanks
Stephen

How to use ShowValue within a UIX/JSP page to display an active link?
I am storing URL's in the DB and want to display them as active links on a UIX/JSP page. I thought that I had this working some time ago, but now it no longer works.
Using <bc4juix:RenderValue datasource="ds1" dataitem="myTextField" /> will display "http://www.otn.oracle.com" as an inactive link using UIX/XML which is expected.
Using <jbo:ShowValue datasource="ds1" dataitem="myTextField" /> will display an active link using if using BC4J/JSP, which is expected.
However, I have not been able to do this using a UIX/JSP page.
Is it possible to use ShowValue within a UIX/JSP page to display an active link?
Thanks,
Bill GHi Juan,
I've done the following and it does not work for me;

<uix:form name="form1" method="GET">

JSP on BEA Weblogic: random error when loading a jsp page that uses a Bean
Hi!
I wrote a simple jsp page that stores a String in a JavaBean, and then forwards to another jsp page to display that String. The jsp pages are deployed on a BEA Weblogic 6 Server, but I get a weird behaviour when loading the page into my browser. Usually I get an error message:
/Response.jsp(9): class 'query.jsp.QueryBean' could not be loaded
probably occurred due to an error in /Query.jsp line 9:
<jsp:useBean id = "queryBean" scope = "request" class = "query.jsp.QueryBean" />
But the funny thing is that after reloading the page a few times it eventually works. The bahaviour seems to be totally random - sometimes it works, sometimes it claims not finding the JavaBean class.
Anyone experienced something similar?
Thank you very much,
CharlieIs QueryBean.class located under '<appname>/Web_inf/query/jsp/'?
If it is please try changing the package name to something else like com.myclass or something like that. -
Need to create a JSP page that informs user how many SMSes are sent.
Hello again ,
My project , which is based on a web-based group SMS module is working , but unfortunately when I send out the group SMS to the selected group , the notification of the sending of SMS is only made visible in the Apache Tomcat status screen . For every SMS sent , the Apache Tomcat screen will display that the SMS is sent to this phone number and recipient number out of the maximium number of recipients.
How can I make a JSP page that would allow me to display these messages instead ? Any help and advice would be welcomed .
Cheers
SeiferiaThe simple way would be to just write a simple jsp that takes the output of the class and displays it. A JSP is nothing more than a servlet class, so you can use your existing classes inside it. If you want to do it the correct way, you should use taglibs to build the JSP. It's up to you.
I suggest buying a good book about JSP's and read that first, else you may be a little overwhelmed. -
Can I Use Swing Components in a JSP Page
Hi,
Can I use Swing Componnents in a JSP Page.If so,Can anybody provide with a sample code.
Thanks.hi,
I wanted to use the JTabbedPane for tab buttons in my
Jsp Page.Is that possible?I am afraid that you can't.
As for GUI (graphics) in the HTML page you can use only the html form elements (but you should simulate other behaviours by dynamically reloading the page).-

Using Java Objects in my JSP page... objects are in a different directory
Hi,
I would like to call and use an object from a JSP page. The java object is in one directory, the jsp is in another. When I call my object, I get a JSP error that says it can't find the object and lists the directory name as part of the file.
For example, here are my two files:
/java/MyObject.class
/web/page.jsp
When I make the call to new MyObject(), I get an error message saying _web.MyObject cannot be found. Any ideas on this?
Thanks!Okay, I figured it out. In case anyone else needs it, here is what I needed to do.
1) I created my object in a package. The JSP page was looking for the object in _dir directory because a package wasn't specified. I created a subdirectory in one of the directories in my classpath and named it the same thing that the package was named.
2) Import the package
3) Make sure all methods in the classes are public, since only public methods can be accessed from outside the package.
Thanks for the help, it got me going in the right direction. -
Problem for getting the real path using one servlet and one jsp page
I have one tomcat machine and several virtual domains. Eahc virtual domain has one realpath in the disc.
I am using one servlet and one jsp page for using this servlet.

public Edicion() {
public String cc(){
ServletContext myContext= getServletContext();
String abspath = myContext.getRealPath("/");
//here i want to return the real path
return abspath;
public static void main(String args[]){
and the jsp page is:
<%@ page import="utils.ticker.*" %>
<jsp:useBean id="tick" class="utils.ticker.Edicion" scope="session"/>
<html><head><body>
<%
tick.cc();
%>
</body></head></html>
But this produces one error, NullPointerException and dont shows me the real path.
Can anyone help me?
thanksi have put this into one sevlet:

I recently upgraded to iOS 7.0. When I open Safari to a blank page, a small "Settings" icon appears against the white background. When I click on it, it opens a link to a web page that is not among my other bookmarks. How can I get rid of it?
Leliforever, cheek you list of installed add-ons, the Ask toolbar can be installed without the users knowledge.
For checking other extensions that may cause this, follow the procedure in this link - https://support.mozilla.com/kb/Troubleshooting+extensions+and+themes -
Using IBook, I can't seem to figure out how to insert a blank page inbetween pages that are already set up, like if you want to add some pictures or something. Anyone have any tips on this? Thanks, Mark
To enable the form to be signed in Reader you will need to open the form in Acrobat; goto Advanced>Enable Usage Rights and then save this copy of the form for sending out to the users.
The user should then be able to edit and digitally sign the form. They can then email the signed/saved pdf as a browsed for attachment or via the email icon in the toolbar. Note - if you have created an email submit button on the form, then unless they have Acrobat they could only return an xml file.
The other way to do this however is to create a dataset by 'distributing' the form. This time the Email Return button will send back a full version of the form. During the distribution setup you will have the option to email the form directly or to save it and send it later,so you can send to users as and when or even post it to a website or intranet.
When you receive and open the returned form it will ask whether you want to add it to the predetermined dataset (or if you want to categorise the returns into geographical areas for example, you could create new additional datasets at this point). If the form is data heavy however, the dataset will become very large and unwieldy pretty quickly, but you can export the data from it (including signatures) in xml format and import this into an Excel spreadsheet.
To simplify the Excel xml import process I'd recommend you carefully structure your form in the hierarchy (LiveCycle) into the order you would want the data items to appear in your spreadsheet and switch off those data items that you will not need by setting the default binding for the irrelevant fields to "None".
Clear as mud? Hope this helps. -
Print only pages that are checked on page one??? Hidden is possible?
Please help. I know a little about java and acrobat but not enough to do everything I want.
I am making a form that has many pages but not all the pages apply to every event. So what I want to do is put a number of check boxes near the top of the form. When I print I only want the pages that are represented by the checked boxes to print. Even better, I would like those pages not visible at all just print. For example: Page one is a form that one would fill out: name, address, phone number, etc. Near the bottom that person would check all that apply: page A, page B, etc. That’s all he would see but when printed, it prints out the form and any of the pages that are checked.
Am I asking too much?
Thank you for any and all help.It's possible to use a script to print only certain pages, but any contiguous page ranges have to be sent as a single print job. For example, to print pages 1-5, 10-20, and the single page 50, you would have to issue 3 separate print statements.
It's possible to have non-visible pages (templates), but it's not possible to print them until they are displayed. Since Reader 11 now supports templates, it would be possible to display the selected pages in the order that you want, which would presumably be a single continous range of pages, which would then require just a single print statement, as opposed to multiple ones as described above. -

I would like to use GarageBand to remaster downloaded music files that are in iTunes. Poorly mastered files keep clipping and damaging my speakers. When I try to use an iTunes file as a new project, it greys out the iTunes songs so I can't select them. Any ideas?
As I said - look whether your original file is damaged or not. If not, I wouldn't change it and find out what in your system makes it sound like it's clipping.
Good sound file, with volume maxed out. No need to change anything.
The same song clipped - no chance to repair. -
