JaspertReports Struts Problem
Hi all,
I have a strange problem using JasperReports, actually I´m using JDeveloper
10g and JasperReport 1.2.8.
The problem start to appears without a reason, at least I don´t see a reason
for it.
I use this for load my jasperReport from my application:
//Parameters:
param.put("NAME",
String.valueOf(carne.getName()));
param.put("LASTNAME",
carne.getLastName().toString());
ServletContext context = session.getServletContext();
File reportFile = new File(context.getRealPath
("/WEB-INF/reportes/carne.jasper"));
InputStream report = new FileInputStream(reportFile);
JasperPrint jp = JasperFillManager.fillReport(report, param,
new JREmptyDataSource());
I know that the reportFile its ok, because if I put a different direction on
it, it throws a not found exception. The problem is with the method
fillReport, now it dowsn´t works, the exception that I recivied is this one:
JRException with the message: Error loading object from InputStream, I know
that is not a version problem beacause I use IReports 1.2.8, like I said,
all worked fine but suddenly not.
Thanks for your help
Struts-DisplayTag(partial list)
Hello, I', using struts framework and displaytag 1.0, all works great. Now, I want to implement pagination using the the partial list (External Paging and Sorting) for displaying records (display tag 1.1 facility). I have this doubt: - For pagination we will be providing display tag only the records that required to be displayed from the full list i.e. if there are 500 records from backend populated in full list, we will be creating a partial list of desired records (say 50) from full list and then feeding this partial list to display tag ? - Or we will be querying backend only for the desired 50 records ? And if so how we take care for sorting, page number etc. ? Can someone share there experience for implementing partial list in display tags? Can someone give me some example code (what to put in the JSP, the action, dao, etc) Thanks!!!

OutputStream out = new FileOutputStream(path);
properties.store(out, "");

Hi all
I have a question, how I can set the path for the OutputStream like i get
it for the InputStream with getResourceAsStream?
This is my code:
Properties properties = new Properties();
String pathToConfigurationFile =
"common/properties/Configuracion.properties";
InputStream input =
Thread.currentThread().getContextClassLoader().getResourceAsStream(
pathToConfigurationFile);
//Load the properties
properties.load(input);
input.close ();
//Set the property datasource
properties.setProperty("datasource", datasource);
//Now I want to save the changes to the properties file
OutputStream out= new FileOutputStream(
pathToConfigurationFile);
properties.store(out, "");
//But an exception occurs and it tells me that the
"common/properties/Configuracion.properties" was not found.
How I can get the correct path for the outputStream like i did with the
inputStream
Thanks!!

Re: Performance issue
Thanks again Leon :)
2007/1/4, Leon Rosenberg <[EMAIL PROTECTED]>:
there are 4 scopes or visibilities/lifecycles of attributes in the
servlet/jsp world.
page : the jsp page, same as local variable in a class.
request: the duration of the request over multiple pages
session: the duration of the user session, over multiple requests
application scope: the whole webapp.
However, talking about one of these scopes, you are always talking
about _one_ server and _one_ webapp.
So the application scope is something which belong to a) webapp and b)
server in first line.
As for multi-server environment - there are a lot of details here, and
I don't really know whether yours handle application scope like a
cluster-scope or not.
I would assume that each server has its own copy created at the start
of the server / deployment of the application.
In my world, if I'd have to implement this requirement I would select
one of two choices:
In both: Create a service which manages the data and speaks to the db.
Option 1. A thread in the application (or timer event, or scheduler)
checks periodically (depending on the requirements it could be 1
minute or 15) with the service whether the local data is still
up-to-date. This can be done by comparing version numbers or creation
timestamps. If not the data in the application scope gets replaced.
Option 2. Service distributes new versions of the data via some
publisher/subscriber mechanism, like JMS, CORBA
Event/NotificationService, or something you develop yourself. The
subscriber resides in the webserver and puts updated data into the
local application scope.
Option 3. You may also use whatever capabilities your environment has,
if any. But I'd be very careful with loadbalancing and scope
distribution, 99.99% of what I saw sofar sucked badly.

Re: Performance issue
Thanks Leon!!!
Ok I made it using the servletcontext like you have said :-), with this
servlet.getServletContext().setAttribute("objHospital", objHospital);
All works fine, even if the user made a mistake :)
One question:
1- I dont understand something about the servletContext, which is the
problem of have multiple-server configuration? In both servers the data is
store in the servlet context right? I guess the problem is that in some
moment the objHospital in one server is diferent to the objHospital in other
server because it change in the database? Or that the actions of one war
don´t have the same servlet context that the actions on other war? I really
don´t understand this, can you explain me that, like i said all works fine
but i want to understand this.
Thanks
Re: Performance issue
Leon!!! something happen... I applied your solution putting the objects in
the request in the preExecute method of the base action, and all works
fine, but... when the user made a mistake, for example leave a required
field in blank, and the ActionErrors validate method of the ActionForm
return the errors, the jsp launch the following exception:
javax.servlet.jsp.JspException:
Cannot find bean under name objHospitals
This only happen when the method validate of the actionErrors returns an
error, why the request is lost or why the jsp don´t found the object? How
can I solve this problem, thanks!!! Hope you can answer Leon

Right, but since the data is readonly its ok to have a copy per
webserver, right? It doesn't harm you to put one data-object (even a
complex one) in the application scope. If you need to check for
updates periodically you could make use of the subject-observer
pattern and notify the webservers from the business layer via
rmi/corba/jms/whatever to renew their data or just check if the data
is still valid and replace it if needed periodically in a separate
daemon thread.

BaseAction extends Action{
private static Data1Class data1;
private static Data2Class data2;
static{
data1 = createData1FromDB();
data2 = createData2FromDB();
}
//now in my actions i have my own execute method, you may have
something //similar:
protected void preProcessExecute(
ActionMapping mapping,
ActionForm af,
HttpServletRequest req,
HttpServletResponse res)
throws Exception{
req.setAttribute("data1", data1);
req.setAttribute("data2", data2);
.
}
protected void postProcessExecute(
ActionMapping mapping,
ActionForm af,
HttpServletRequest req,
HttpServletResponse res)
throws Exception{
}
public abstract ActionForward myExecute(
ActionMapping mapping,
ActionForm af,
HttpServletRequest req,
HttpServletResponse res)
throws Exception;
public final ActionForward execute(
ActionMapping mapping,
ActionForm bean,
HttpServletRequest req,
HttpServletResponse res)
throws Exception {
preProcessExecute(mapping, bean, req, res);
ActionForward forward = myExecute(mapping, bean, req,
res);
postProcessExecute(mapping, bean, req, res);
return forward;
}
}
You just have to ensure, that when an Action overwrites preProcess it
calls super.preProcess.
The advantage of this method is, that actions at the end of the
hierarchy have a chance to overwrite the data by the base action,
which is quite useful for internationalization and such.
Same rules for updates as for servletContext apply.

Re: Performance issue
Thanks Leon, about using the servlet context, I read that on a distributed application the share information of the servlet context is not entererly global right?: *"...In the case of a web application marked "distributed" in its deployment descriptor, there will be one context instance for each virtual machine. In this situation, the context cannot be used as a location to share global information (because the information won't be truly global). Use an external resource like a database instead."* About the second solution that you gave to me, I do not understand, you said that for example in my BaseAction Class create a method to put the objects in the request? The problem is that in every request the application will go to the database to load the objects and then put them on the request! What I do not understand is how to put the objects in the request without have to go the database each time that a request is made and the method in the BaseAction is call. 2007/1/2, Leon Rosenberg <[EMAIL PROTECTED]>: The easiest way is to initialize the data once in the init(ServletConfig) method of the servlet and put them into the application scope (servletcontext). The struts tags will be able to access the data directly, so you don't need to change a bit. Of course the data structures theirself must be threadsafe to access, which shouldn't be a problem if you are only reading them. Alternatively you can perform this in a static initializer in a action and put them in the request scope of each request (if you have a common code block all actions are passing through, like authorization) or into the application scope on first request (which would need a bit of synchronization with double checked locking) regards leon On 1/2/07, Daniel Chacón Sánchez <[EMAIL PROTECTED]> wrote: > Hi all, I'm using struts framework on my application, but I have a > perfomance question. > > When my application starts I load objects in session that may or may not > will be used (depends on what the user does), for example I load the health > centers, hospitals, countries, etc, that will be available for the users in > html:selects, I know that to had many objects in session is not good, in > fact each time the user click on one application option (menu) all the > objects in session are erased, except the ones that I load on the start of > the application.

Performance issue
Hi all, I'm using struts framework on my application, but I have a perfomance question. When my application starts I load objects in session that may or may not will be used (depends on what the user does), for example I load the health centers, hospitals, countries, etc, that will be available for the users in html:selects, I know that to had many objects in session is not good, in fact each time the user click on one application option (menu) all the objects in session are erased, except the ones that I load on the start of the application. Is there a way (maybe a pattern) to load this objects in the moment that are needed, and not load all at the start of the application.

You can use this code:

Re: Get real path of an action
Thanks, Yeap, but how can i use it on the jsp:
retrieveURL('*(realPath)*/mostrarRegistrarPersona.do', 'PersonaForm')
Thanks
Re: Get real path of an action
Ok let me try to explain it better.
From the *registrarPersona.jsp* I use ajax to call some actions, one action
is found by the ajax call and theother don´t.
This is the call to ajax:
retrieveURL('*actualizarCamposForm.do*?paso=paso1', 'PersonaForm') --->*
found*
retrieveURL(*'mostrarRegistrarPersona.do*', 'PersonaForm') --> *don´t found*
In the struts-config.xml:
I guess that de mostrarRegistrarPersona action is not found because It make
references to the jsp in where I already be, */JSP/registrarPersona.jsp* and
the action is not found. So I need to obtain the real path (all the
direction of the action) to find it not matter in which JSP i call it, not
matter in which level of the context i be.

Re: AJAX + Struts, IE Problem
Frank ist seams like it's a caching problem This is a note for myself but it could be useful for anybody writing some Ajax calls. If you use a GET method to send an asynchronous request to your server side code, if you don't do anything Internet Explorer will cache locally your request, so obviously you won't have the latest result in your response. So instead of scripting something like this in Javascript (unless you use a POST method): var url = 'GetCustomers.aspx?country=ireland' use this: var url = 'GetCustomers.aspx?country=ireland' + *"&dummy=" + new Date().getTime();* This will force IE to show a fresh version of your request all the time. Firefox doesn't seem to have this problem apparently. What I don´t know is how to put that parameter in the retrieveURL function Click Here I can obtain the getTime value like this: <% long time= new Date().getTime(); %> but how i can put in here that value: Click Here Thanks for all the help Frank

Re: Out of topic, Oracle SEQUENCE
Well you where correct, this is the answer of a metalink user: user_seq.CURRVAL (with two R's) is the last number that was assigned in your session. Even if records are added in other sessions, your CURRVAL remains the same. Try it. Open two SQL*Plus windows (you can even use the same username) and see that CURRVAL in one remains the same even while CURRVAL in the other increases.

Hi I know this the struts mail list, but I have a question and I hope that someone know the answer I'm using an oracle database, I have a sequence to obtain the nextval that will be the key of the row that I will insert, after the insert I need to know which is that value so I can tell the user with which value the row was inserted. Is there a sure fire way to do this, or am I stuck with "select max(id) from table" and hope nothing else has been inserted in that few milliseconds it takes to go from my insert statement to my select statement? Some code, for better explanation: CREATE SEQUENCE user_seq INCREMENT 1 MINVALUE 0 NOMAXVALUE START WITH 0 NOCACHE NOCYCLE insert into users values (user_seq .nextval, 'userName'); Then I need to know the value with which the row was inserted, how can I do that Thanks!

Re: Double Execution of Struts Actions
I understand all that, but It not have to happen, fot me its a bug, because the action don´t have to be call twice, no matter that the property of the td was wrong 2006/9/9, Laurie Harper <[EMAIL PROTECTED]>: That's not a Struts bug, it's a common HTML coding error. IIRC, the 'background' property of a TD specifies the URL of an image to place as the background, not a colour; at least, that appears to be what's happening here. As with , the image URL is being interpreted as the current page, so when the browser sees that TD, it tries to use the current page URL to load the background image -- hence, hitting the action again.

The app works fine, but my logs show that the first execution is the 'real' one. But there is also a log of another call through the code. I can't figure out where this one is coming from or going to. Someone who can help me, i saw anothers threads about this topic but none had solved the problem! (Spanish) *Doble llamado a una acción de struts* Extrañamente algunas veces cuado llamo a una acción se llama* 2 veces*, es extraño porque llevo trabajado bastante con struts y esto nunca había pasado
