Get and Set XSP-Session Attributes errors
Hello, I have to set and get a user name in my web-application. I use a xsp-session and followed the sample from Cocoon Developer's handbook : using content logic XSP about authentification. But if I write exaclty the same pages, I get this error: org.apache.cocoon.ProcessingException: Exception in ServerPagesGenerator.generate(): java.lang.NullPointerException But why? I checked the session:set-attribute name=userxsp:expruser/xsp:expr/session:set-attribute line, and it seems correct. The string user is not null. So why do I get an error Thanks - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

AW: xsp-session and JAVA sessions
from within an XSP you can have a session be created by specifying the xsp:page's attribute @create-session=true (this is handled by the session logicsheet. this way a session will be created if it didn't yet exist. problems can occur with these sessions, though; sessions created by the session logicsheet from within the XSP are created when actual generation begins, i.e. after pipeline setup. thus, transformers in the pipeline (for which the XSP is the generator) won't see the session instantly. your safest bet is to create the session before the generator step (e.g. via an action) and have the generator access this one via the session logicsheet. -Ursprungliche Nachricht- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Auftrag von [EMAIL PROTECTED] Gesendet: Mittwoch, 26.

RE: xsp session logicsheet
Hi Cyril,
try adding
xmlns:session=http://apache.org/xsp/session/2.0;
namespace to your xsp page. Then have a look at the generated code.
Basically you should see a java variable (object) named session, with it
you can do what you want. No need to declare it, cocoon does it for you.

Subject: Re: xsp session logicsheet
Thanks for you response.
hum, I guess actions are still a little bit too complex for me, regarding my
knowledge of Cocoon...
Isn't it really possible to add merely values to the same session's
attribute with the ESQL logicsheet? It sounds odd...
Cyril.
Hi Cyril
Why don't use an action, I think it's better not to have too much Java
code
in your xsp-pages.
In an action you can take your code as it is.

Hi,
I would like to deal with session through xsp, and serve as far as
possible
the same goal as with the following servlet: e.g put all the parameters
named 'item' in the object of type Vector 'items' bound to the current
session, so that it would be possible to list at any time all of the
items
chosen so far by the client in his session.
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
res.setContentType(text/html);
PrintWriter out = res.getWriter();
// Get the current session object, create one if necessary.
HttpSession session = req.getSession(true);
// Cart items are maintained in the session object.
Vector items = (Vector)session.getAttribute(cart.items);
if (items == null) { items = new Vector(10,5);}
String item = req.getParameter(item);
items.add(item);
session.setAttribute(cart.items,items);
out.println(HTMLHEADTITLESessionTracker
modifie/TITLE/HEAD);
out.println(BODYH1Session Tracking Demo/H1);
// Print the current cart items.
out.println(You currently have the following items in your
cart:BR);
if (items == null) {
out.println(BNone/B);
}
else {
out.println(UL);
for (int i = 0; i items.size(); i++) {
out.println(LI + items.get(i));
}
out.println(/UL);
}
out.println(/BODY/HTML);
}
}
Below is the xsp i've written for the moment,: this is working fine,
but
does not do what I want: because each time the client chooses an item
and
pass it via the parameter 'item', instead of being added in the object
cart.items, its value overrides this of the preceding parameter.

xsp-session:get-attribute name=cart.items/
br/
bYour session was created:/b xsp-session:get-creation-time

Some of you would know how I can improve my code? Indeed, I would like
cart.items to be like a Vector, so that it would be possible to put
merely
values onto it.
Thanks in advance for your help,
Cyril.

Re: xsp session logicsheet
Hi Roman,
Indeed I've done this:
?xml version=1.0?

xmlns:xsp=http://apache.org/xsp;
xmlns:xsp-session=http://apache.org/xsp/session/2.0;
xmlns:xsp-request=http://apache.org/xsp/request/2.0;

default=not set/
br/
bYour session was created:/b xsp-session:get-creation-time
as=string/
/html
/xsp:page
My problem is the following: I would like to add items to the attribute's
session 'cart.items'.
For the moment, the preceding code doesn't do this task.
When I call http://localhost:8080/cocoo/mount/try/session.xsp?item=3
I receive the following html result:
The list of items is: 3
Your session was created: Wed Feb 05 13:41:32 CET 2003
when I then call http://localhost:8080/cocoo/mount/try/session.xsp?item=5
The result is the following:
The list of items is: 5
Your session was created: Wed Feb 05 13:41:32 CET 2003
and of course, I would like
The list of items is: 3, 5
Your session was created: Wed Feb 05 13:41:32 CET 2003
What i would like to know : is it possible to achieve this task by using
Session Logicsheet by itself, does this Logicsheet provides this
functionnality?
If not, the alternative is also to use actions, as suggested in this thread
before?
Is a built-in action available for this, or do I have to build one from
scratch?
Any help or hint would help me,
Thanks,
Cyril.

Er, no. But you probably didn't mean ESQL anyway.
You need to do it as you did it before: retrieve the value, add a new
element to it and then store it again.
// Cart items are maintained in the session object.
Vector items = (Vector)session.getAttribute(cart.items);
if (items == null) { items = new Vector(10,5);}
String item = req.getParameter(item);
items.add(item);
session.setAttribute(cart.items,items);
Would translate to
xsp:logic
Object items = xsp-session:get-attribute name=cart.items/;
if (items == null) items = new Vector(10,5);
((Vector) items).add(xsp-request:get-parameter name=item/);
request.getSession().setAttribute(items);
// logicsheet only supports setting Strings objects :-(
// thus do it manually.
/xsp:logic

Mind you that items is declared of type Object because that cast to
Vector might result in a NPE when applied to null. Thus size() and
get() method are not declared for this object! You need to cast it
first (and probably assign it to a variable of type vector).

Re: xsp session logicsheet
Hi Roman,
thank you very much for your reponse.
I know that in theory, using actions is better than simply mixing pure Java
code in XSP pages. But it's true that I must go quite quickly, and just to
have an idea of how sessions work in Cocoon, I just would to have a first
try with the second solution. Of course, I have in project to have a deeper
understanding of what goes on under the hood with actions, but a little bit
latter. AFAIK, this concept is not really simple to figure out...
The solution you suggested to me works well, thanks:
?xml version=1.0?
xsp:page
xmlns:xsp=http://apache.org/xsp;
xmlns:xsp-session=http://apache.org/xsp/session/2.0;
xmlns:xsp-request=http://apache.org/xsp/request/2.0;
create-session=true
xsp:structure
xsp:includejava.util.Vector/xsp:include
/xsp:structure
content
xsp:logic
Vector items = (Vector)xsp-session:get-attribute name=cart.items/;
if (items == null) items = new Vector(10,5);
items.add(xsp-request:get-parameter name=item/);
session.setAttribute(cart.items,items);
bThe list of items is:/b xsp-session:get-attribute name=cart.items
default=not set/
/xsp:logic
/content
/xsp:page
But the result is of the following form:
The list of items is: 1336364336433643323643
and I would like better it would be of this form:
The list of items is:
.133636
433
643
3643
323643
So instead of the following code,
bThe list of items is:/b xsp-session:get-attribute name=cart.items
default=not set/
I' ve tried the following one:
bThe list of items is:/b
ul
for (int i = 0; i lt; items.size(); i++) {
lixsp:expritems.get(i)/xsp:expr/li
}
/ul
I have the following error:

org.apache.cocoon.www.mount.essai.session3_xsp
Christian Haul has already taken pains (one more time) to explain me what
went wrong, but I'm afraid I've not all understood. I've casted the former
Object items onto Vector one, as suggested,
but it doesn't seem to be sufficient.
Have any idea?
Regards,
Cyril.
Hi Cyril,
you do not have to use actions if you do not want :-)
As I said, when you use session namespace, there is always a variable
session there in the generated java code. You can access this session
either
directly in xsp page from within xsp:logic tags, or you can write your
own
taglib. This taglib can then implicitly use session variable, though it
will
never be declared there. What I propose to you is a kind of dirty
programming style, but as I understood you want a quick solution.
Try something like this, you have to experiment and always look at the
generated code:
?xml version=1.0?
xsp:page
xmlns:xsp=http://apache.org/xsp;
xmlns:xsp-session=http://apache.org/xsp/session/2.0;
xmlns:xsp-request=http://apache.org/xsp/request/2.0;
create-session=true
html
xsp:logic
// beginning of the java code
try {
// Cart items are maintained in the session object.
Vector items = (Vector)session.getAttribute(cart.items);
if (items == null) { items = new Vector(10,5);}
String item = req.getParameter(item);
items.add(item);
session.setAttribute(cart.items,items);
/xsp:logic
bThe list of items is:/b xsp-session:get-attribute name=cart.items
default=not set/
/html
/xsp:page

Subject: Re: xsp session logicsheet
Hi Roman,
Indeed I've done this:
?xml version=1.0?
xsp:page
xmlns:xsp=http://apache.org/xsp;
xmlns:xsp-session=http://apache.org/xsp/session/2.0;
xmlns:xsp-request=http://apache.org/xsp/request/2.0;
create-session=true
html
xsp-session:set-attribute name=cart.itemsxsp-request:get-parameter
name=item//xsp-session:set-attribute
bThe list of items is:/b xsp-session:get-attribute name=cart.items
default=not set/
br/
bYour session was created:/b xsp-session:get-creation-time
as=string/
/html
/xsp:page
My problem is the following: I would like to add items to the attribute's
session 'cart.items'.
For the moment, the preceding code doesn't do this task.
When I call http://localhost:8080/cocoo/mount/try/session.xsp?item=3
I receive the following html result:
The list of items is: 3
Your session was created: Wed Feb 05 13:41:32 CET 2003
when I then call http://localhost:8080/cocoo/mount/try/session.xsp?item=5
The result is the following:
The list of items is: 5
Your session was created: Wed Feb 05 13:41:32 CET 2003
and of course, I would like
The list of items is: 3, 5
Your session was created: Wed Feb 05 13:41:32 CET 2003
What i would like to know : is it possible to achieve this task by using
Session Logicsheet by itself, does this Logicsheet provides this
functionnality?
If not, the alternative is also to use actions, as suggested in this
thread
before?
Is a built-in action available for this, or do I have to build one
xsp session
Hi,
I would like to deal with session through xsp, and serve as far as possible
the same goal as with the following servlet: e.g put all the parameters
named 'item' in the object of type Vector 'items' bound to the current
session, so that it would be possible to list at any time all of the items
chosen so far by the client in his session.
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
res.setContentType(text/html);
PrintWriter out = res.getWriter();
// Get the current session object, create one if necessary.
HttpSession session = req.getSession(true);
// Cart items are maintained in the session object.
Vector items = (Vector)session.getAttribute(cart.items);
if (items == null) { items = new Vector(10,5);}
String item = req.getParameter(item);
items.add(item);
session.setAttribute(cart.items,items);
out.println(HTMLHEADTITLESessionTracker modifie/TITLE/HEAD);
out.println(BODYH1Session Tracking Demo/H1);
// Print the current cart items.
out.println(You currently have the following items in your cart:BR);
if (items == null) {
out.println(BNone/B);
}
else {
out.println(UL);
for (int i = 0; i items.size(); i++) {
out.println(LI + items.get(i));
}
out.println(/UL);
}
out.println(/BODY/HTML);
}
}
Below is the xsp i've written for the moment,: this is working fine, but
does not do what I want: because each time the client chooses an item and
pass it via the parameter 'item', instead of being added in the object
cart.items, its value overrides this of the preceding parameter.

xsp-session:get-attribute name=cart.items/
br/
bYour session was created:/b xsp-session:get-creation-time
as=string/

/xsp:page
Some of you would know how I can improve my code? Indeed, I would like
cart.items to be like a Vector, so that it would be possible to put merely
values onto it.
Thanks in advance for your help,
Cyril.

Re: xsp session
Hi Cyril
Why don't use an action, I think it's better not to have too much Java code
in your xsp-pages.
In an action you can take your code as it is.

RE: xsp-session : Bug with Cocoon? or Bug with programmer?
After searching the created Java file (apologies for my earlier
mistake), the request helper is the only place it could be trying to set
the variable.
For example the following XSP (entire file) :
+-+
?xml version=1.0?
xsp:page
xmlns:xsp=http://apache.org/xsp;
xmlns:xsp-session=http://apache.org/xsp/session/2.0;
create-session=true
page
xsp-session:set-attribute
name=fruitApple/xsp-session:set-attribute
fruitxsp-session:get-attribute name=fruit//fruit
/page
/xsp:page
+-+
Generates the following Java
+-+
public class test_xsp extends XSPGenerator {
static {
dateCreated = 1037088922427L;
dependencies = new File[]{
};
}
/* Built-in parameters available for use */
// context- ServletContext
// request- HttpServletRequest
// response - HttpServletResponse
// parameters - parameters defined in the sitemap
/* User Class Declarations */
/**
* Generate XML data.
*/
public void generate() throws SAXException, IOException,
ProcessingException {
this.contentHandler.startDocument();
AttributesImpl xspAttr = new AttributesImpl();
this.contentHandler.startPrefixMapping(xml,
http://www.w3.org/XML/1998/namespace;);
this.contentHandler.startPrefixMapping(xsp,
http://apache.org/xsp;);
this.contentHandler.startPrefixMapping(xsp-session,
http://apache.org/xsp/session/2.0;);
this.contentHandler.startElement(, page, page, xspAttr);
xspAttr.clear();
this.characters(\n);
XSPRequestHelper.setSessionAttribute(objectModel,
String.valueOf(fruit),
this.characters(Apple);
);
this.characters(\n);
this.contentHandler.startElement(, fruit, fruit, xspAttr);
xspAttr.clear();
XSPObjectHelper.xspExpr(contentHandler,
XSPRequestHelper.getSessionAttribute(objectModel,
String.valueOf(fruit), ));
this.contentHandler.endElement(, fruit, fruit);
this.characters(\n );
this.contentHandler.endElement(, page, page);
this.contentHandler.endPrefixMapping(xml);
this.contentHandler.endPrefixMapping(xsp);
this.contentHandler.endPrefixMapping(xsp-session);
this.contentHandler.endDocument();
}
}
+-+
So as you can see from the above the only place it is possible creating
the session variable is
XSPRequestHelper.setSessionAttribute(objectModel,
String.valueOf(fruit),
this.characters(Apple);
);
And this is where the rogue semicolon appears.
I can remove the rogue semicolon by creating the String Apple and
reverencing that string through xsp:expr tags. But this leads to a
nullPointerException.
I think that either I am being really dim with this or some powers that
I can't control are at work here!

Unfortunately this makes no difference.
The cocoon version is 2.03
Going to try downloading the 2.03 for JDK 1.4 binary - see if this makes

I think that either I am being really dim with this
or some powers that
I can't control are at work here!
Thanks for everyone's help so far

RE: xsp-session : Bug with Cocoon? or Bug with programmer?
Are you sure you're looking at the right section of your xsp? The section you've quoted doesn't match, making it most likely that something else in your xsp is causing the problem. Search for fruit in the generated java file you've been looking at - you should find something almost identical to: session.setAttribute(String.valueOf(fruit),Apple); XSPRequestHelper should never enter the picture. By the way, the XSP creates a java file to be compiled, not JSP. Geoff Howard --- Tom Place [EMAIL PROTECTED] wrote: My apologies. I made a typo on this message (not in cocoon).

RE: [Auth-Framework] Using xsp-session and session namespaces
Hi, you can put the session transformer in your pipeline behind your serverpages generator - but then you don't have access to the authentication information in your xsp. If you need this, you have to write your own logicsheet for the authentication framework. In this logicsheet you can embed any java. What you have to do then is to lookup a session manager component and can invoke according methods to get the information.

Re: [Auth-Framework] Using xsp-session and session namespaces
Thanks Carsten after thinking about that all the afternoon and half of the night fighting with the 2 pipelines (curently 1:00 a.m here). I comes to the same place .( I need a logicsheet since I am working with XSP. I am trying to working on this logicsheet since 9:00 p.m. BTW, I think many people using XSP (like me) need this logicshhet. I thinked about to write it and (if you want) built-in into Cocoon like an standard logicsheet that will do the same work as the well knowed session:getxml. What about that? My main problem is how to get the SessionContext from Java in a xsl from scratch. I am reading and reading the Cocoon API. Now I know the packages are the: org.apache.cocoon.webapps.authentication org.apache.cocoon.webapps.authentication.acting org.apache.cocoon.webapps.authentication.components org.apache.cocoon.webapps.authentication.context org.apache.cocoon.webapps.authentication.generation org.apache.cocoon.webapps.authentication.selection and maybe more, who knows I am also going into and trying to understand the Cocoon Java code and trying to write it. But I dont know how. Anyway I am a very hardhead ;) I will try until I will get this, because I need it to check the permission of the user for more than 120 pages. Its a database application in Cocoon. Also it can help me to change password, etc. Maybe this can be my mastering in Cocoon! Who knows :) I know you are very busy, but can you help me a little more just some tips, please.

[Auth-Framework] Diference between xsp-session and session
Can someone explain what is the diference between xsp-session and session? I am trying to do this. But does not work: xsp:page xmlns:xsp-session=http://apache.org/xsp/session/2.0; xmlns:xsp=http://apache.org/xsp; document xsp-session:getxml context=authentication path=/authentication/data/full_name/ /document /xsp:page My main development is using XSP and I cannot get the authentication data in anyway. I need to use then: xsp:page xmlns:session=http://cocoon.apache.org/session/1.0; xmlns:xsp=http://apache.org/xsp; Then after generate a servepage, I need to do a transformation to make work the session name space. All this works fine. But when I need to use esql. This all the stuf is broken. The serverpages is generated first and then he cannot use session:getxml context=authentication path=/authentication/data/full_name/ to filter the result of a query. What can I do?

RE: difference between xsp-session and session
xmlns:xsp-session=http://apache.org/xsp/session/2.0;
There is no difference as long as the namespace URI is the same. The
namespace prefix is just a short name for the namespace URI.
That's what I assumed at first, but as one example showed otherwise.
** How about the necessity of create-session=true ?
** How can I use the session- or request-object within a xsp:logic
Like in :
xsp:logic
boolean isTrue() {
boolean result = false;
String language = (String)session:get-attribute
name=somename/;
or (String) session.getAttribute(somename);
return ;
}
xsp:logic
This give me a compilation-error because no object session can be found.
This method gets compiled as class-method but as session is not defined globally, this
doesn't get compiled.

Re: xsp-session ns calls element creation funcs?
Hi, I had the same problem with esql in a Dynamic XSLT using XSP. There was no solution found or given, so I made a workaround and skipped the logic sheet and did everything straight in Java.
