Re: JavaScript/JSP Question
Hi,
Yes, there is a way. It is not related to Tomcat in any way but...
what you need to use is string.indexOf(string2)
So, take the value of the current item in the combo box and see if it
contains the string you are searching for using the indexOf() method. This
is a JavaScript issue though so I suggest if you have further problems you
try addressing comp.lang.JavaScript (available from Google).
If the indexOf() method does not find the substring it will return -1 if it
does, it will return it's index.

Andoni.

I'm using the following JavaScript to create lists of restaurants by

Is there a way to modify the script to accept a value for the restaurant
name that would
be similar to a %LIKE% function in MySQL when the user hits the submit
button?
Thanks,

This question is not tomcat specific so I'm marking [OT].
I believe Javascript has the same startsWith/endsWith string
functionality that Java has.
You should be able to simulate that pretty easily.

JSP question
Hello All,
I am pulling my hair on this problem, and since there are many Java experts
on this mailing list, I hope someone can help me on this.
I have a simple servlet that calls a JSP page where the user can enter a
search value. When the user clicks on the submit button, the search value
will be passed back to the servlet for processing and display. All these
are running on Tomcat 4.1.24.
Everything works fine until I added the form validation routine in the JSP
page. Initially, my input button type was submit. I changed it to
button and leave the submission to the form validation routine which is in
JavaScript. Now, when I click on the button, I get the error message of:
Object doesn't support this property or method
at the line of code:
document.form1.submit();
Does anyone know why? The following is code of the JSP page:
//code begin--
html

RE: JSP question
A better solution for what you're doing is to leave the button as
type=submit and remove its onclick event. Instead, add an onsubmit
handler to form that calls return validateForm() - return false in your
function when validation fails.

Matt

RE: JSP question
Hi There,
Why dont you change the button back to a submit and then add a
onSubmit='return validation();' to you form ?
Thats what we do
Eg.
Script
function valid () {
if (document.form.val.value.length 1) {
alert(Please enter a value);
return false;
}
return true;
}
/Script
form onSubmit=return valid();
table
tr
td
input type=text name=val
/td
td
input type=submit
/td
/tr
/table
/form
Thanks

Most likely document.form1 is not visible in the browser object model.
There are various ways to address the form, but the most portable in this

Re: JSP question
Thanks for the reply. But this cannot be true. If I leave the textbox
blank, I got the alert. That means it is seeing the document.form1
object. It just does not like the .submit() method which I can't understand
why.
Thanks.

Actually, after the post I figure using the %@ include filefilename % would be
useless because it was static
So I started to look at %jsp:include ... \ for dynamic includes, and then soon
realized it was more trouble that it was worth :)
So I have decided just to redirect to individual jsp pages based on
applicationJar.getPageName() instead of including dynamic content in a common page

Re: General HTML/jsp question, any one
To convert the string to xml compliant string, you could use a custom tag to convert to quot;, to lt;, et c. instead of having an input tag, you could have a custom tag such as filtered-input.

I think you are generating you html by concatenation of strings or so.

JSP question
I'm working on a web application that will be used by about 150 people concurrently. One of the requirements is to show text field hints in the status bar whenever the mouse passes over a text field. All of the hints are stored in the database. I need to write a class that will be available at the application level that returns some javascript along with the correct hint for whatever field the mouse is currently over. Since there are over 1000 fields in this web application, I'm looking for alternatives to writing a class with a get method for each field. What would work very well is if I could pass an argument in a getProperty call. For example, jsp:getProperty name=testBean property=hintText value=firstName / That way, I could store the values in a hashtable and just get whatever one was requested. Of course, I can't do that. I also can't set a property then immediately call get property to get the one I just requested in the set since the class is going to be shared by all users. Can anyone suggest a way to do this? I feel sure there must be a way, but I can't think of it. Thanks --Michael
Re: JSP question
Assuming you have a controller servlet that could load the hint text from the database, why not have a static hashtable in your servlet code that is initialized with the values from the database in the init() method. Then as each session is initialized, you could put a reference to the hashtable in each session with session.setAttribute(hints, hintTable); Then you have access to the hints wherever you need them. jsp:useBean name=hints class=java.util.Hashtable scope=session ... input type=text name=myField onMouseOver=self.status='%= (String)hints.get(myField) %' Or better yet you could write a custom taglib... mytags:textWithHint name=myField and then do the hint lookup in the custom tag code. You could even have your hashtable stored and initialized in the taglib code. Then your pages would never need to know about it. I hope these ideas help...

RE: RE: newbie jsp question
From the Javadocs for java.lang.VerifyError (great source of information, by
the way):
Thrown when the verifier detects that a class file, though well formed,
contains some sort of internal inconsistency or security problem.
So I would say that somehow your JDBC drivers are corrupt. I have seen
JBuilder produce classes that caused this - a simple recompile fixed
everything for me. The Stack Trace would seem to indicate the problem is in
interbase.interclient.ErrorKey. I would suggest trying to create a
standalone application that exhibits this problem and contact the vendor's

Duplicate Class Names in JSP Question
I have the following code in one of my .jsp files. %@ page import=com.redsoft.ems.beans.app.User % %@ page import=com.redsoft.ems.tags.app.User % It causes the errors listed below. Interestingly, if I comment out either page directive, I don't get the error. I also verified through testing that the problems seems to be related to the ending classname being the same (ie. User). I created two classes with the same class name, but in different packages and still had the same problem.

Re: Duplicate Class Names in JSP Question
The generated Java class for your JSP page is required to be legal Java code -- and it's not legal to import both of these names in the same source file. Therefore, your program is in error.

XML version of JSP question
Hello. I've looked through the archives, but I haven't seen a solution to this problem. I'm using XSLT to create a JSP page and to get that to work, I am using Tomcat 4.0 Release Candidate 1 (on a Windows 2000 box, only running Tomcat--no Apache nor IIS). But the simple tests of the XML-version of JSP I'm using seems to process all the scriplets first, and then the HTML. For instance, this code in regular JSP format returns the right results: % int a = 15; % htmlheadtitlehi there/title/head body Hi. My variable is: %=a%. br / % out.println(I like mongeese!br /); % /body/html **the results*** Hi. My variable is: 15. I like mongeese! ** While the XML-style, which looks like this: ?xml version=1.0 ? jsp:root xmlns:jsp=http://java.sun.com/JSP/Page; version=1.2 jsp:scriptlet int a = 15; /jsp:scriptlet htmlheadtitletest/title/head body Hi everyone! The number is: jsp:expressiona/jsp:expression.br / jsp:scriptlet out.println(I like the mongoose!br /); /jsp:scriptlet /body/html /jsp:root Returns this: 15 I like the mongoose! Hi everyone!

(I'm assuming that I have to stick a line in web.xml?) 2) How do I get Tomcat to render XML-style JSP in the right order, just as regular style JSP renders?

Take care with the case sensitive.
A way to see which parameters were passed is using a code like:
%@ page import=java.util.*%
html
head
/head
body
pre
%
Enumeration e = request.getParameterNames();
String s = new String();
while(e.hasMoreElements()) {
s = (String) e.nextElement();

The parameter %=s% has value%=request.getParameter(s)%br

}

Java Beans and JSP Question.
I have a standard java bean. The different thing about it is that I
usually have two overloaded set methods per attribute. For example,
public class MyBean {
private int a;
public setA (int a) throws Exception {
if (a 100) throw new Exception (Must be less than 100);
}
public setA (String a) throws Exception {
try {
setA(Integer.parseInt(a));
} catch (NumberFormat Exception exception) {
throw new Exception (Format incorrect.);
}
}
//I usually have one getA
public int getA() {
return a;
}
}
Now when I use this bean in a JSP that is stored in the request scope,
at times the compiler will complain that it cannot find a get method for
A. Even though one get method for that particular attribute is
clearly there.
Some added information, I use Forte Community Edition 2, and Tomcat.
Forte's compiler complains about one attribute while Tomcat complains
about another completely different attribute it cannot find the get
method for. Which makes me itch with anger. The note is my example
above is very simple. I used it just to explain my problem. My actual
bean has about 17 attributes all with 2 setter methods each and 1 get
method each.
Does anyone know how to resolve this issue?
Thanks for your help.

Re: Java Beans and JSP Question.
I spent some time chasing the same problem. It
appeared to me that the Introspector was getting
get/set methods in pairs based on the property name,
parameter list, and return type. It seemed to expect
that you adhered to the Java beans standard of
void setA(int a){}
int getA(){}
where the return type of the getter matched the input
parameter of the setter. It matched up get/set method
pairs that way.
So in your case the pair would be
void setA(int a)
int getA()
void setA(String a)
null
It then iterated through the list of methods looking
for one that matched the *name* I had requested. It
sometimes found the pair where the getter was null
before finding the other pair and caused the error
you've found.
I fixed it by renaming my method to setAasString() or
something like that. A bit ugly, but I couldn't find
another way to make the introspector behave.

Doing this violates the design patterns for getters and setters listed in the JavaBeans specification. Therefore, the JDK's introspection logic will not recognize this as a property. You need to either have only one setter (with a type that matches the corresponding getter), or you must define a BeanInfo class that specifically lists the method names and parameter types of your getter and setter methods.

Java Beans and JSP Question.
Dear Dan,
I believe I'm familiar with the problem you're having and think it's related to Forte.
In my case, either Tomcat or Forte complained about methods that were clearly there.
What I've had to do is take my bean and put it in two places. Within Explorer in
Forte which shows my filesystems I have
c:\tomcat\webapps\myApp\WEB-INF\classes\com\koyuru. I have also had to directly mount
com\koyuru as a filesystem within Forte as well. If I modify a bean in one, I must
copy it to the other, otherwise either Tomcat or Forte will complain.
In my case I was using examples from the jspBook and tried to modify them but Forte
claimed my new method wasn't there. It didn't seem so related to overloading as much
as the filesystem. That shut it up though.

private int a;
public setA (int a) throws Exception {
if (a 100) throw new Exception (Must be less than 100);
}
public setA (String a) throws Exception {
try {
setA(Integer.parseInt(a));
} catch (NumberFormat Exception exception) {
throw new Exception (Format incorrect.);
}
}
//I usually have one getA
public int getA() {
return a;
}
}
Now when I use this bean in a JSP that is stored in the request scope,
at times the compiler will complain that it cannot find a get method for
A. Even though one get method for that particular attribute is
clearly there.
Some added information, I use Forte Community Edition 2, and Tomcat.
Forte's compiler complains about one attribute while Tomcat complains
about another completely different attribute it cannot find the get
method for. Which makes me itch with anger. The note is my example
above is very simple. I used it just to explain my problem. My actual
bean has about 17 attributes all with 2 setter methods each and 1 get
method each.
Does anyone know how to resolve this issue?
Thanks for your help.

Doing this violates the design patterns for getters and setters listed in the JavaBeans specification. Therefore, the JDK's introspection logic will not recognize this as a property. You need to either have only one setter (with a type that matches the corresponding getter), or you must define a BeanInfo class that specifically lists the method names and parameter types of your getter and setter methods.

Java Beans and JSP Question
Dear Dan,
I believe I'm familiar with the problem you're having and think it's related
to Forte. In my case, either Tomcat or Forte complained about methods that
were clearly there. What I've had to do is take my bean and put it in two
places. Within Explorer in Forte which shows my filesystems I have
c:\tomcat\webapps\myApp\WEB-INF\classes\com\koyuru. I have also had to
directly mount com\koyuru as a filesystem within Forte as well. If I modify
a bean in one, I must copy it to the other, otherwise either Tomcat or Forte
will complain.
In my case I was using examples from the jspBook and tried to modify them
but Forte claimed my new method wasn't there. It didn't seem so related to
overloading as much as the filesystem. That shut it up though.
Shawn
I have a standard java bean. The different thing about it is that I
usually have two overloaded set methods per attribute. For example,
public class MyBean {
private int a;
public setA (int a) throws Exception {
if (a 100) throw new Exception ("Must be less than 100");
}
public setA (String a) throws Exception {
try {
setA(Integer.parseInt(a));
} catch (NumberFormat Exception exception) {
throw new Exception ("Format incorrect.");
}
}
//I usually have one getA
public int getA() {
return a;
}
}
Now when I use this bean in a JSP that is stored in the request scope,
at times the compiler will complain that it cannot find a get method for
"A". Even though one get method for that particular attribute is
clearly there.

about another completely different attribute it cannot find the get
method for. Which makes me itch with anger. The note is my example

white space in JSP - question from a newbie
I ran across a problem while trying to learn how to program with tomcat/jsp.
I was running a simple case statement and got an error stating Statement
not reached.
=
Error: 500
Location: /lucas/switch.jsp
Internal Servlet Error:
org.apache.jasper.JasperException: Unable to compile class for
JSPC:\bin\tomcat\3.2.3\work\localhost_8080%2Flucas\_0002fswitch_0002ejspswit
ch_jsp_3.java:74: Statement not reached.
out.write(\t\r\n\r\n);
^
===
I couldn't figure this out for a while until I understood out how to view
the java produced by the jsp code. Because my case statement had
whitespaces between jsp tags the jasper engine decided to produce out.write
statements in the wrong place.
I modified my jsp to work but I wanted to ask if this was a bug.
I can just format my code differently, but it seems like a error other
newbies would make and I am sure it can get a bit nastier with more
complicated code. Is this behaviour part of the spec or can I expect
different implementations to behave differently.
Rodney
Here is a listing to reproduce the error. I have fixed most of the
whitespace problem exept for the case statement just before monday.

Jsp question
Let's say I have multiple forms on a page. Does anyone know if I can retrive the name of the form that was submitted using the request object? or if there is any other way to find out. Thanks! Fredrik
Re: Jsp question
Two quick ideas: 1. Include in each of your forms a html hidden tag that has a name value that will be common for each form, and a value dependent on the identity of the form. Then you can get from the request object the expected key value and find the form. input type=hidden name=FormVariable value=FormNumber2 2. If every one of your forms has some sort of submit button, you can give that button a common name for all forms, and a value dependent on the form its a part of. input type=submit name=FormVariable value=FormNumber1 Hope that helps, Matt - Original Message - From: Fredrik Liden [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, June 28, 2001 1:44 PM Subject: Jsp question Let's say I have multiple forms on a page.

Tomcat/JSP Question
Hi, Forgive me for the beginner question but I am trying to instantiate a class for a JSP. I am using: jsp:useBean id = "EX" class = "Example" scope = "session" / Thus I am under the assumption that my "Example" class is being instantiated and the constructor is called, is this incorrect?Basically I am trying to instantiate a class for a session and was wondering if this is the way to do it. And so if it is can I access class objects, I am assuming I am supposed to use jsp:get_property jsp:set_property rather then EX.counter where counter is a property of the "Example class" Once again sorry for the newbie question and thanks for any help you can give!! Mike
RE: Tomcat/JSP Question
I think you may have the syntax for jsp:get_property jsp:set_property wrong. It is jsp:getProperty() and jsp:setProperty() Here is a textbook example from Fields and Kolbs book.

RE: Tomcat/JSP Question
Title: RE: Tomcat/JSP Question
Try putting in get/set methods for the object, then getting them that way, e.g.:
--
public Object getMyObject()
{
return myObject;
}
public void setMyObject(Object _o)
{
myObject = _o;
}
% Object myObject = EX.getMyObject(); %
--
The get/set methods will allow introspection.
Or, if you want to just get it directly, you need to have a semicolon on the end, like this:
--
% Object myObject = EX.myObject; %
--
For regular code in the jsp, you need to enclose it in % % and follow regular syntax rules. If your bean had a String property, you could get it this way:
--
%=EX.myString%
--
The %= % is shorthand for % out.print( );%.
Kinda confusing at first, but you get used to it. Hope this helps...

mod_include/jsp question...
I'm trying to use Apache to parse the bulk of a web page, pulling in a small amount of JSP in the footer with SSI. I'd like the page to be SHTML, and the footer to be JSP. But I'm having trouble... apparently, mod_include doesn't treat included files exactly the way Apache does. (I am _not_ specifying IncludesNoExec). My question is: can you use SHTML to #include a JSP, such that Apache handles the SHTML part and Tomcat handles the JSP part? If so, where could I find some specific information for setting this up? thanks, nate roe - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
