NEWBIE JSP QUES

I'm really new at jsp, and have a frustratingly simple question. All I'm trying to do is get a .jsp page to display in internet explorer. So I create the file and put this in it:
<%
String test = "this is a test";
%>
<html>
<%=test%>
</html>
And nothing displays!!! I've also tried not using "Sting" before the variable, but it still shows nothing when I open the file in Internet Explorer. Any explanation would be appreciated.

all I did was download and install j2sdkee1.2.1 from java.sun.com. (already having jdk 1.2.2 on my system) and then ran j2ee.bat (in ROOT:\j2sdkee1.2.1\bin). This started the J2ee server. Then all I did was put my .jsp files in the ROOT:\j2sdkee1.2.1\public_html folder and point my browser to http://localhost:8000/<name of jsp>.jsp.
So do I need to get Tomcat?

Newbie - JSP & bean shopping cart logic error?

Hello,
I am attempting to bulid a shopping cart facility on a JSP site that I am building.
I am having difficulties adding an item to the basket.
The page below (bookDetail.jsp) displays items for sale from a database. At the foot of the page, I have set up a hyperlink to add an item to a basket bean instance created in this page.
What happens is the page will load correctly, when i hover the mouse over the hyperlink to add the item to the basket, the status bar shows the URL of the current page with the details of the book appended. This is what I want. But when I click the link, the page will only reload showing 20% of the content.
Netbeans throws up no errors, neither does Tomcat, so I am assuming I have made a logical error somewhere.
I have enclosed the Book class, and the ShoppingCart class for your reference.
Any help would be really appreciated as I am at a loss here.
Cheers.

Newbie - JSP and TAG library problem

I am trying to execute a JSP program on a server with
jakarta-tomcat-4.1.29.
Here is a program:
<%@ taglib uri="testTagURL" prefix="testTagPrefix" %>
<testTagPrefix:myFirstTag/>
in web.xml I have definition:
<taglib>
<taglib-uri>testTagURL</taglib-uri>
<taglib-location>/WEB-INF/tld/testTag.tld</taglib-location>
</taglib>
I have testTag.tld file located at: /WEB-INF/tld
When I execute my program I am getting:
org.apache.jasper.JasperException: File "/test-jsp/testTagURL" not
found
My question: how come my program is looking for "/test-jsp/testTagURL" and
not for "/WEB-INF/tld/testTag.tld"?
Thanks,
Zalek

means what it says.
If you look in the file WEB-INF/displaytag.tld you'll see it
has a definition for a custom tag, I'm guessing it's called column.
The tld states that this tag has an attribute called "value". ie that
in a jsp file you would write
<display:column value="SomeSuperValue" /> However the java class that implements that custom tag
does not have a setter method for value. ie. the class
org.displaytag.tags.ColumnTag is missing the method
public void setValue(String value) { .... }

Newbie: jsp compile error w/ tomcat 5.0.19

Hello there, this is my first time try to write something in jsp/ servlets, and i encounter a minor installation problem:
using mdk linux with j2sdk1.4.2 (locate at /usr/local/), tomcat is also locate at /usr/local.
I am able to see HelloServlet.java, and HelloWorld.html at http://localhost:8080/servlet/HelloServlet
and http://localhost:8080/testing/HelloWorld.html
but i'm unable to see HelloWorld.jsp at http://localhost:880/HellowWorld.jsp (my HelloWorld.html and HellowWorld.jsp are locate at the same dir)
here's are the things i added in my /etc/profile so far:
CATALINA_HOME="/usr/local/Tomcat"
export CATALINA_HOME
JAVA_HOME="/usr/local/j2sdk1.4.2"
export JAVA_HOME
JavaPath="/usr/local/j2sdk1.4.2/bin"

export CLASSPATH
when do java -verison, i see:

Using CATALINA_HOME: /usr/local/Tomcat
Using CATALINA_TMPDIR: /usr/local/Tomcat/temp
Using JAVA_HOME: /usr/local/j2sdk1.4.2
i thought i did everything that was told, yet i can't see jsp page on my browser, while i can see servlets and html,
thank you for your time in advance ^_^

sorry, it was a typo, yea...it was for http://localhost:8080/testing/Hello.jsp
this morning, i copied "tool.jar" from j2sdk1.4.2 to my /usr/local/tomcat/common/lib, restarted, fire it up again using "./catalina.sh" just to see where the problems came from, and here's where the compile error occue:

looking over the compiler error, it seems to me tomcat is able to recongize /usr/local/j2sdk1.4 's location. which i assume it implied JAVA_HOME and CLASSPATH are setup correctly.
Dunno why it just won't display jsp pages and kept saying compiler error...
thank you for helping

Newbie jsp question

Hello, I am coming from php, and I was looking for a server side language I could use, but would also hide the source code(meaning i can give people a binary to put on there servers liek with regular java,c,or c++). I searched around for information reagrding this and jsp, and I am unable to tell if i can just give the jsp server a compiled app to run. I am interestd in writing some simple webapps such as a webmial interface, do you think that js pis too overboard for a project like that? Do you guys know of any other server side langauges that might be more useful to me in a situation like that, but can also run off compiled programs instead of reading a script like php and perl? Sincerely,
Jason

java binaries (bytecode) do not hide implementation. All that is lost in compiling java sources are tho comments and variable names. Even more, if compiled without the parameter -g:none, some debuging info is left in the bytecode, so it is possible to determine the name of the local variables. For someone who is familiar to java, reading a decompiled source is not very difficult.

Newbie jsp/javabean

Hello,
I'm trying to do my first web app. First I must log a user from a server database. I thought using JSP to display html pages and javabean to contain logic and functions. In my first page there are a login form with a submit button. How can I call a javabean after pressing button and then read a validate property value from it to login again or pass to next form? To call logic procedures must call setproperty method and do anything inside?
Thanks,
Julian.

You do realize that Java runs on the server don't you? So it you want use java to validate, you would have to do this:
1) submit username + password to a JSP or servlet
2) inside that JSP or servlet, read the values from the request and validate them using your bean
3a) if correct, go on
3b) if not correct, display error message and show login form again
How to call the javabean depends on what you are using. If you are using scriptlets, simply call the method as if it were a regular java class. If you are using JSTL, you should read up on that right now because learning that by just coding away is far to difficult. Check out the book you can download for free on this website.

1) One of my pages, takes around 10-15 seconds to load in the browser. I'm assuming thats because tomcat is putting it through some compilation process (does a JSP page get dynamically converted to a servlet at runtime?) This is not just on the first access, but any subsequent request. There is only a few db queries and some XML output using XJTL.
In $tomcat\conf\web.xml I've set
<init-param>
<param-name>development</param-name>
<param-value>false</param-value>
</init-param>
<init-param>
<param-name>checkInterval</param-name>
<param-value>60</param-value>
</init-param>
under the JSP servlet element, but it seems to make no difference.
2) I' m an experienced ColdFusion developer, so alot of the tag based concepts are the same, but I'm finding the datatypes are a lot more focused, where the CF datatypes are very generic and no real casting is required. In CF there is a "CFDUMP" tag which you can throw any variable at and it will recurisvely write it out, no matter how deep the array or structure. Is there anything similar for JSP?
Any help is appreciated.
Cheers,
Jon

1) >This is not just on the first access, but any subsequent request.
The jsp transforms to a servlet on first request. The servlet is compiled and executed and its this output that's streamed to the browser. The keyword is 'first request' which in turn means the first access may be a bit slow (& which can be overcome by precompilation), but if subsequent access to the resource still takes a long time, you have other problems.
The check interval in tomcat's web.xml is to address a wholly different issue. Its the interval that the container checks for newer versions of the jsp (in a development environment) and will not solve your problem.
2) Hmmm, you want to output readable data when you print out a variable ? For user defined datatypes, you could override the toString() method in the class.
cheers,
ram.

Newbie : JSP session problem after reload with IE refresh button.

Hi,
I had an issue with JSP reloading using tomcat 4.* and IE.
I have a jsp1.jsp is opened in two different IE windows(one by one). Once i refreshed using IE refresh button from the first window, its loaded with second windows session details. Its changess whole http request object with second window.
Am not sure , why its happening ? Could anybody shed light on this ?
Thanks and Regards
PV

Hello,
No, am not saving any form details . But i noticed session id is changing completely for the first window once i loads frame on the second window.
javascript:alert(document.cookie) Above scriptlet (IE address bar) returns session id from the second window rather than current window without refreshing, that means, its removed whole request completely or somehow manipulated previous sessions. Can anybody explain this behaviour ?
Thanks

Newbie JSP/Servlet general question

Hi,
I am currently studying the life cycle of a JSP page from the Java EE 5 Tutorial (http://java.sun.com/javaee/5/docs/tutorial/doc/bnahe.html). This document says that: "+If an instance of the JSP pages servlet does not exist, the container loads the JSP pages servlet class, instantiates an instance of the servlet class, initializes the servlet instance by calling the jspInit method+".
My two questions are:
i) Does this JSP servlet implement the HttpJspPage interface defined in javax.servlet.jsp?
ii) Does Struts and Spring MVC provide such JSP servlet Java classes implementations or are these part of other packages? If not, which packages offer such implementations?
Thanks,
J.

Newbie: JSP Setup (WBL6) ? _ TIA

Hello, I am trying to test a simple JSP page i created ( JSP code =
          "<%= "Hello" %>", but i am getting an error page (Error Message
          described below)
          I probably didn't set up correctly but I couldn't find anything on the
          edocs about setting JSP.
          This is what I did:
          - Install Weblogic 6
          - Found the path to index.html (http://localhost:7001/index.html)
          - Created the sample JSP page and placed it on the same path as
          INDEX.HTML
          - Replaced index.html for mypage.JSP
          (http://localhost:7001/mypage.jsp)
          - Received error message.

This might sound very silly, but when i download tomcat? do I need to upload that to my web space? Or jsp pages just won't work if my web space provider didn't offer that?
Do i need to install tomcat so that I can view it? or others can view it?
Sorry for the silly questions, but I am just so confused right now. Thanks for all the help.

Newbie: JSP - JSPX

I am trying to create an app in jdeveloper. after following examples with JSP (pages), i got a few pages up and running. My pages were a combination of html with a few buttons for navigation, with the html formatted via CSS - pretty simple stuff. Now I need to add some fairly complex interface components, and I have read that it is "suggested" that developers use JSPX (documents as opposed to pages) when they are going to use ADF components.
So I thought I would begin again but with JSPX instead of JSP - but I cannot get it to make sense... If I include html elements (eg <div id="anId"> for formatting, and plain text with links included some places) - these will not be well formed XML elements (?), and they do not show in the development environment's design view - however they appear when I run/deploy. Maybe this is just a fluke?
Am I missing something?? how do I use html elements (text, links, layout etc) in JSPX? all the examples I find have bound fields to display information - but this surely cannot always be the best way to show basic information.
Should I use a combination of JSP and JSPX (JSP for the simple pages that are mostly info, links (html), and use JSPX when i want heavier app stuff)???
any comments / tips / links are appreciated...
/caj

thanks for you comments! I actually got this working myself before reading your relpy, but I did extactly what you suggested - so it was great to get a confirmation that I am on the right track...
I just got a bit too caught up in using adf:document and panel pages, like in oracles SRDemo app (these were much too complex for my initial needs). I am now creating simpler pages OK, hopefully things will go smoothy when I come to the pages with more complex structures (tree menu with a work area that changes based on the chosen branch).
I have now come to another issue (with backing beans), which I will no post in a new post!
thanks!!!

NEWBIE JSP Deployment Problems

I know this is will probly bore to some of you but I'm trying to evalutate this software.
I created a test JSP via the wizard and ran it in Jdev ok. Deployed and Copied the files to the Apache web server provided with 8.1.7. Ran on browser and got this error:
java.lang.RuntimeException: JSP Registry could not locate runtime property file:....
I included the business classes but apparently I'm still missing something...
I have been searching for documentation on this error but not much luck so far...

I have deployed a JSP with BC4J Application on an Oracle IAS and it works fine, but to do it i had to include a path to the .jar file that contains my classes in Jserv.properties
When i need to change, add or manipulate something in the jar file or include a new jar file, i have to shut down the service because while active, the files that are being pointed by the conf file become locked... I have read something about "zones" and i have no idea about apache or OracleJSP configuration. I began yesterday to read the JavaServer Pages Developer4s Guide and Reference... But it has 420 pages and i will last a lot till i find what i4m looking for.
If you can explain me the way you make your jar file accesible by the system in a correct way or the pages in which it is explained, please, make me know.

Newbie ACE Ques:

Hi
Cat6k
"sup-bootdisk:s72033-ipservicesk9-mz.122-18.SXF8.bin"
ACE10-6500-K9 with 3.0(0)A1(3b)
What is the recommend way for session persistence or if no recommend, what do most folks use? IP-Source-Address, Cookie injection from ACE or Cookie injection from the WebServers
I am testin IP-Source-address. Any body can post sample configs?

First UPGRADE.
A1(3b) is DEAD !!!
Go to A2(1.1) as soon as possible.
The best sticky method for HTTP traffic is most probably cookie injection from ACE.
But more CPU intensive than sticky source-ip.
Gilles.

Newbie: Advanced Queing sample...

Hello,
I'm new to Oracle AQ, so I'm researching whether or not this is what we want to use - we would like to setup a messaging queue to be accessed using web services and soap calls via the internet.
I see the advanced queuing sample for Oracle 9i, but we have installed the Oracle 10g database - I'm wondering if I can just install and run that sample as is? Or is their a better sample out there I can reference for the web service wrappers around the enqueue/dequeue messages, and how to set that up?
Can anyone point me in the right direction for a good sample app to reference for the developing the client app for referencing Oracle AQ?
Thanks,
Greg

You have to install the samples from the companion disk or download, but the samples are older than 10g. Also read the docs on this and you may find some answers to what you need to do.

No me funciona el Response Urgente que te cagas

Me da este error:
Servlet API error : send Error with commited buffer
Es urgente mis huevos dependen de ello.

Ver�s resulta que estoy trabajando con un servidor Tomcat 3.2.1
Y sin motivo aparente el maldito se caer sin previo aviso. He revisado TODAS la conexiones y esta se cierran correctamente. Cierro todos los statement, los resultSet, las llamada a procedimientos almacenados,... Todo lo cierro todo, y el maldito se sigue callendo sin mostrar un patr�n. Usamos el Poolman.jar como pool de conexiones. Y lo �nico 'raro' que he hecho, ha sido crearme unos tags de jsp que se lanzan en todas las p�ginas. No se me ocurre que puede ser. Sabr�as a que se puede deber. Much�simas gracias
Un saludo.
