Hi,
I fixed my problem by setting the system wide variable (WindowsXP)
CLASSPATH to r:\\dealershop\\WEB-INF\\classes.
Thanks,

Is it possible to include JSF into JSP-Servlet application?

I have an existing JSP-servlet application. I am wondering if it is OK to add new pages to this application in form of JSF?
Thanks

Just learn JSF and it will all be clear.
They can perfectly co-exist and you can perfectly link or redirect from one to other (plain GET requests), you can perfectly share the same session and application scoped attributes, but for POST requests (forms submits) from JSP to JSF or vice verse you just need to understand how the one handles/expects the request parameters and that kind of stuff.

How to run JSP/Servlet applications on Apache?

As we all know that tomcat is an JSP/Servlet engine. Apache is a web server not a JSP/Servlet enabled web server. Then in order to run JSP/Servlet applications on Apache web server on unix, what should I do?
Thanks.
James Liu

Can you give me some detailed information about how to combine Apache and Tomcat? Note, the application is going to run on Sun Solaris Operating System.
By the way, where do you put your final version of application? on windows or on Unix? on tomcat or on apache?
I am building the application using tomcat on windows, but now I almost finished the application, so I decide to move it to Unix which uses apache as the web server. But I got problems, the Servlet engine (JServ) can not understand "RequestDispatcher" (an object used to redirect jsp pages).
Help please.

General design tip needed to write a small Jsp/servlet application

I am developing a small application using few JSP pages and a single servlet(as it iwas told to me that, number of servlet should be 1).
My problem is,
I have multiple JSPs. and multiple button within each JSPs.On click of each button, requeswt should be sent to Servlet and servlet performs some logic for esch button clicked.
I have 2 option to identify the button clicked and write the logic.
1.Servlet will get the value of each button.I will write one 'if loop' each for one button value. Whichever (request.getParameter("btnxyz")) returns 'NOT NULL', corresponding 'if loop' gets executed.This works fine.but servlet code looks like a mess as number of if loops = total number of buttons of all jsps.
2.Have a hidden field in each JSP.Onload of the button i will write some value to the field.On exit of JSp i will make it null.So, when button is clicked, in the servlet i will first identify the JSP from which request has come. and then identify the button as in step1.
My question is , which option is better?
Please suggest me other better solutions for the same.
Thanks,
Gowtam

Have you considered using Struts?
It would make your life so much easier.

Sample JSP&Servlet application required?

hey all
iam new to jsp&servlets
i did read some tutorials about the basics
and i want any link to a tutorial or a project that uses both jsp&servlets
any help?

At the risk of sounding really dumb the examples are just too complex. There does not appear to be anywhere on the web where I can find a simple JSP/servlet/bean example of the type I described. There is enouigh material describing each individual component, but what I need is an example to cement the ideas, but the ones suggested are too much for a newbie. Even the much vaunted Pet Store thingy causes my eyes to glaze over.
I dont expect anyone to have written something with my exact requirements, but surely to goodness there must be something that:
1. On entry presents a search form on a table (e.g. EMP)
2. On submission list all rows in EMp matchiung the criteria.
3. The user can either click the link 'Edit' which opens up a form dispalying the row allowing the user to edit and save the changes, or click the 'New' button to show a blank form to create a new EMP.
All this via a Controller servlet, with the database logic handled by a java bean, and all the presentation done via JSP.
To me this is the most obvious and instructive example of this technology, but after days of trawling the web, and looking through a number of books, I cannot find such a thing.
CGI with Perl DBI/DBD was a breeze to work with compared to this stuff ..... maybe ASP with SQL/Server would be a more fruitful use of time.

Please state your problem that you are having more clearly so we can help.
I looked at your code I here are a few things you might consider:
It looks like you are putting freely typed-in comments from end-users into an xml document.
The problem with this is that the user may enter characters in his text that have special meaning
to xml and will have to be escaped correctly. Some of these characters are less than character, greater than character and ampersand character.
You may also have a similiar problem displaying them on your JSP page since there may be special characters that JSP has.
You will have to read up on how to deal with these special characters (I dont remember what the rules are). I seem to recall
if you use CDATA in your xml, you dont have to deal with those characters (I may be wrong).
When you finish writing your code, test it by entering all keyboard characters to make sure they are processed, stored in the database,
and re-displayed correctly.
Also, it looks like you are putting business logic in your JSP page (creating an xml file).
The JSP page is for displaying data ONLY and submitting back to a servlet. Put all your business logic in the servlet. Putting business logic in JSP is considered bad coding and will cause you many hours of headache trying to debug it. Also note: java scriptlets in a JSP page are only run when the JSP page is compiled into a servlet by java. It does not run after its compiled and therefore you cant call java functions after the JSP page is displayed to the client.

For a simple JSP/Servlet application, is JBoss better than Tomcat?

Hi,
We have a simple JSP/Servlet/Struts application which currently runs inside a Tomcat container. Are there any advantages to move to JBoss in terms of better memory management or things like that?
Thanks in advance.
Niranjan

If your requirements and application is small and simple then I think that Tomcat is OK atleast Tomcat is clean and simple. Tomcat gives you slight better performance as compared to JBoss on simple sites but please google to find out how can you tune your tomcat to give you desired output.

Install an application through the configurator

Dear All
we wrote an application running very well on iPhone 3 and 4.
Then i tried to install un upgrade. Unfortunately I get always the same error:
The program could not be installed on the phone.-Error: A signed resource has been added, modified, or deleted.
I reset both phones, it still does not let install the program. What is wrong? We regenerated the profile and the program,
but nothing helps. it's impossible to install the program. Always the same error.
Any idea, where could be the problem? Do I have to reinstall the configurator or iTune?
Thank you for a hint.
George

When you say, "locked" was already deselected, I take it that you mean the small icon at the bottom right of the Get Info window displayed an open lock picture.
Have you tried locking it, then unlocking it again? I expect you will be able to lock it by simply clicking on the open lock icon, but to unlock it again you will need to supply an Admin password.
Odd that DU didn't fix it. That would be my first thought also. Suggest trying it again, if you haven't already done so.
Speaking of DU, have you verified your HDD?

Not able to access the application through URL in clustered environment.

Hi,
I recently depoyed my application on clustered environment of weblogic 8.1 SP4.
Now I am able to access the application through the managed server name with port number but not able to access through URL.
For ex
http://machine1:7001/test/login.do?m=begin
this is accessible
If I use
http://test.domain.com/test/login.do?m=begin
Then application is not accessible.
any HTML or JSP page page is in reach by both the URL.
Please suggest me what should I do in this regard.
thanks

Hi Syed,
I meant to ask are you able to see the application you created in Hyperion Planning Login page,if yes try accessing the created application through Hyperion Planning(Try restarting Planning Services once even if you are able to launch hyperion planning page) url "http://servername:8300/HyperionPlanning and selecting the application you created.
And also could you please let me know if you are logging in to workspace through admin username ? and also check if you are able to see the application in shared services and try to provision any group on that application.
(The Assumptions are if application is not created successfully then it will not be available in workspace to launch and if its in maintainance mode (Application Maintenance Mode) in Application Settings and last would be check OHS and Hyperion Planning Services)
Thanks

How to call jsp /servlets running in different web application in tomcat

hello all,
i have 2 web applications(Charts and Reports) in the same tomcat,i want to call jsp/servlets running in the Reports webapp from Charts webapp.how do i achieve this.
thanx
ravi

You can also use getContext(String context) in the ServletContext class to get a request dispatcher.
Using the above example it would be :
// in a servlet in the charts webapp
ServletContext context = getServletContext();
ServletContext reportsContext = context.getContext("/reports");
RequestDispatcher dispatcher = reportsContext.getRequestDispatcher("/path")
dispatcher.forward(request, response);Just note, that depending on your server's configuration getContext(...) might return null.

You can add a webapp using console but not a servlet individually.

Business Intelligence -- Servlet Application

Hello
I have created Business Intelligence --> Designer and then
I have created Servlet Application through
New --> Business Intelligence --> Servlet Application
It working fine and runs with url
http://192.168.1.237:8988/dw-dw_proj-context-root/mypackage1.BIController1
I want to define a alias for it i.e.
user can access it with the url
http://dwapp/ {How to define such alias?}
I want to make different tiers how to do that i m new so plz guide me

Have your application been deployed to an application server? If yes, you can define a virtual root to point to the url of the servlet application. If no, you may want to create a page that redirects the user to the servlet application.
Thanks

Deployment of BC4J/JSP/Struts application to tomcat-4.18

Please see the online help for deploying JSP web applications. The instructions are under User Guides, Developing Web Applications, Developing JSPs and Servlets...
There are a number of dependency archives that need to be deployed to your webserver in order for the BC4J JSPs to run correctly.
IF you look at the Project Properties for your JSP project, you will see a number of them such as Connection Manager, ORacl e8.1.5 JDBC, etc. EAch of these libraries is based on one or more .jar or .zip files which need to be present in your webserver.
Which ones you deploy somewhat depends on how you have deployed your Business Components app module. The online help provides more details.
The Oracle JDBC classes are all located in <JDEV_HOME>/jdbc/lib/oraclex.x.x/classes111.zip. Where x.x.x is the version of the drivers. 8.1.5 is the default in JDev 2. and 3.0.
