Re: Multibox problem when defaulted all on
I'm still a little hazy on when reset is called on forms, but you may want
to try moving
marketing = marketingItems;
to the forms constructor, so when the form is created the first time its
holding the default values.
And inside the reset method:
marketing = null;

Subject: Multibox problem when defaulted all on
I am having a problem with multibox. I need to have a set of checkboxes to
default on in my form. I found and followed Ted Husted's Struts Tip #7
http://husted.com/struts/tips/007.html - Use Multibox to manage
checkboxes and everything works well, except in one condition explained
below.
When everything is defaulted on, and the user checks off the boxes but
leaves at least one checked on, everything works as planned. However, if
all
the boxes are defaulted on (as in the code below) and the user checks all
the boxes off, the marketing array is not updated. In this case, the form
ends up telling me that the checkboxes are all on.
How do I get it to work properly in this situation?
-
Form:
public void reset(ActionMapping mapping, HttpServletRequest request) {
...
marketing = marketingItems;
}
private String[] marketing = {};
private String[] marketingItems =
{accountHolder,user2,user3,user4,user5};
public String[] getMarketing() { return this.marketing; }
public void setMarketing(String[] marketing) { this.marketing =
marketing; }

Re: Multibox problem when defaulted all on
I don't think I explained myself quite clearly.
WORKS: All the checkboxes on the form default to on.
WORKS: User leaves all checkboxes on.
WORKS: User turns some of the checkboxes off.
DOESN'T WORK: User turns all of the checkboxes off.
In the last situation, the form reports to the action that the marketing
array still has the value of {accountHolder, user2, user3, user4,
user5}, even though the user turned all the checkboxes off.
This is because when nothing is selected, nothing gets sent to the form to
be populated, so assuming your form is in session scope, whatever you had in
there when it was rendered, is still in there. That's why inside the reset
method of the form you need to empty that string array. That way if there
are value submitted they will be populated, and if there are none, it will
stay at none.

Re: Something after RequestProcessor adding extra / to URL?
Wendy, Not certain where the trailing / is coming from, but I believe as soon as it encounters the ? everything past there is considered parameters, so basically if you seperate everything left of the ? and its a working url, great.

Tomcat and matching actions
Hey all.. I have experienced some really stupid behavior of tomcat/struts when combined.. let me explain. In web.xml if you map *.do to the struts action servlet you are able to match actions with paths, ie /blah/something.do correctly gets matched to /blah/something (the .do gets stripped.. still don't understand why) But what really irks me is I need to do some directory matching, ie in web.xml i have /getDocument/* mapped to the struts servlet. But in my struts config I cannot match /getDocument/**, the only way I can match is based on file extensions because the /getDocument/ gets stripped, so im forced to matching *.pdf, *.zip.. etc! Is there some way to fix this?? Or a suitable good alternative? Thanks, David - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Tiles attributes problem
First the sample code:
XML defintion:
definition name=.default path=/tiles/layouts/base.jsp
put name=header value=/tiles/header.jsp/
put name=menu value=.menu.main/
put name=body value=${body}/
put name=footer value=/tiles/footer.jsp/
put name=logon value=/tiles/logon.jsp/
put name=title value=CMC/FLEX Sales Web/
put name=messages value=/tiles/messages.jsp/
put name=path value={path}/
/definition
my editUsers.jsp
%@ taglib uri=struts-tiles.tld prefix=tiles %
tiles:insert definition=.default controllerUrl=/admin/editUsers.do
flush=true
tiles:put name=path value=/admin/userManagement/
tiles:put name=menu value=.menu.prospect/
tiles:put name=body value=/WEB-INF/apps/admin/editUsers.jsp/
/tiles:insert
Now here's the problem, my controller action basically prepares its view by
doing some logic and placing things in the request etc. My editUsers.jsp
(the body content one) relies on the tiles attribute path for links to other
webpages. This is the crazy thing, if i set my TilesAction (editUsers.do)
to return null as its actionForward somehow the tiles context does not get
passed to my editUsers.jsp!! However if I DO return an actionForward its
fine! What the heck is up with that? Having to return an actionForward
defeats the purpose OF the tile does it not?? Any ideas? (PS the way I
found out it works if I specify a forward was in my struts-config i set
success as the forward to /WEB-INF/apps/admin/editUsers.jsp... but that
obviously messed up my whole definition by not using anything but that
content page)
Thank in advance,

Encode/Encrypt url parameters?
Hi I was wondering if there are any easy to use Java classes or otherwise that could be used to encrypt or encode url parameters? Basically what I want to do is this: Action (encodes the url parameters, puts them into the request object) - forwards to jsp containing a link that grabs those parameters from the request - click link takes you to an Action that decodes and uses them. The parameters are to files on our site.. its no big deal because they are in the web-inf directory and unaccessable from the web but I'd rather hide them from the surfers anyway.

I don't know the layouts of your jsps or what you are doing in them.. but JSP's are inherently non-static because they use runtime expressions to generate the html, and that can change on a per request basis.

[OT] Question about CSS inheritance/cascading
Hey I am using CSS like most everyone, I was wondering if its possible to
apply multiple styles to a single element?
IE I have a table cell, in my CSS it automatically receives this style:
TD {
color : #00;
font-family: Arial, Verdana, Times;
font-size: 10pt;
}
and by specifying class=Blue I can make it change the text color:
.Blue{
color: #323299;
}
however I'd also like to add a bottom border element to it ie:
.BlueThinBottomBorder {
border-bottom: 1px solid #323299;
}
Is it possible within the class= to specify multiple style sheets to apply
and if so how?
(The idea is to keep me from having to make a BlueTextBlueThinBottomBorder
style)
Thanks,
David

Re: [ot] hibernate jndi
Mark, I had initially setup my hibernate to try and bind to a JNDI name created by tomcat in the server.xml and it failed to work with that, I ended up setting up hibernate to create its own JNDI name put its SessionFactory there. Then I used a Filter based plugin to give out session's and close them as needed. I'd imagine you could have your own servlet put hibernate into a JNDI name and as long as that name is available to the other webapps they could have plugins to grab sessions from that SessionFactory. -David - Original Message - From: Mark Lowe [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Wednesday, January 07, 2004 4:20 AM Subject: [ot] hibernate jndi Has anyone any words of wisdom when it comes to configuring a jndi service for hibernated classes that ideally only runs a service from a webapp?

Dependent Drop Down Boxes

Best Practice: Dealing with null inner objects within forms
Ok well I've been fighting this problem for months now and have never really
figured out the best way to deal with it. I'll give a short description
hopefully it makes sense:
public class Parent {
private String firstname;
private String lastname;
private Address address;
.. getters/setters etc.
}
Ok now my form object basically just has a getter/setter for a Parenty
object.
Within my jsp I want to use html:text elements for parent.firstname,
parent.lastname, AND parent.address.street, parent.address.city,
parent.address.state, etc. Now the problem is address has the potential to
be loaded as null from the database if an address record is not tied to the
parent. So in that case my jsp will throw a null pointer exception because
it tried to initialize the text element from a null'd variable member. But
even if there is no record for that I want to be able to edit the field and
add one if its submitted. This doesn't pose a problem for
firstname/lastname because the parent object will never be null.
The alternatives that I can see to solve this:
1) Use logic:notEmpty tags to display the textbox as long as there is a
record, but if theres not the user won't be able to edit on that page, so
that doesn't really solve the problem
2) Within my parent object in its constructor initialize any member object.
IE:
public Parent () {
address = new Address()
}
3) Within the form's constructor make sure all of its member variables
variables are non null. IE:
public myActionForm() {
parent.setAddress(new Address());
}
I don't like this though because that requires me to edit the form
everytime I change ANY of the objects contained therein.
4) ??
I hope that was clear.. any alternatives or what is everyone else doing to
deal with this problem?
Thanks,
David

Quoting David Erickson [EMAIL PROTECTED]: Hey I have been reading a lot about threading lately from the JLS and otherwise.. but my question is what would be an example of a non-threadsafe action? Struts manual said that only one instance of an action exists in the JVM.. and when I run an action each thread creates its own versions of all the variables within the action correct? More precisely, you get per-thread *local* variables (i.e. those defined inside a method). If you use *instance* variables (those defined in the class, rather than inside the method, there is only one copy of those variables -- and you get in trouble if you use those variables to store information that is specific to a particular request. So assuming I'm not accessing some outside 'global' variable, everything is inherintly threadsafe right? If anyone can give me an example of what 'not' to do that would help tremendously. thanks, David Consider the LogonAction class in the struts-example app. Note that the username and password variables are defined inside the execute() method, so they are local variables (and therefore have a copy per thread). What would happen to your logon processing if you moved those variable declarations to be outside the method instead of inside? Then, if you had two people logging on at the same time, the single copy of the username and password variables would be at risk for getting scribbled on by the second user. The most important rule for thread safety is to use local variables to store anything that is specific to a particular request (using instance variables to store read-only copies of things needed by multiple requests, on the other hand, is fine).

try this solution From Gogeneni Pratima:

in the application.properties you should have:
view.construction.error=liCould not construct view because: {0}/li
e.getMessage() is substituted instead of {0}

Re: Form and Pass the Form to the Business Tier
However, I have to supply a number of additional
properties for the business tier to process. For
example, the property threadType is to be assigned to
zero manually and the property parentPostID is to be
found from another class, how do I code them in the
form bean? Do I use get methods shown below (without
set methods)?
public int getThreadType() {
return 0;
}
This is fine I assume.
public int getParentPostID() {
return ParamUtil.getParameterInt( request, parent
);
}
This wouldn't work properly. I would make a setter for parentPostID and in

html:hidden name=yourformname property=parentPostID value=%=
request.getParameter(parent)%/

Re: Form and Pass the Form to the Business Tier
Thank you for your response.
According to my understanding of your advice, if I
want to pass a hidden field from JSP to a form bean, I
must have name=myFormName in the JSP's html:hidden
tag? Please confirm.
From the docs:
The attribute name of the bean whose properties are consulted when rendering
the current value of this input field. If not specified, the bean associated
with the form tag we are nested within is utilized. (RT EXPR).
I always put it as good practice.
Another additional property that is to be assigned a
value in my form bean is now with Timestamp type.
Do I code this way in my form bean class? Please
confirm:
pubic Timestamp getNow() {
return DateUtil.getCurrentGMTTimestamp():
}
Ya that looks fine.

Example of a non-threadsafe Action?
Hey I have been reading a lot about threading lately from the JLS and otherwise.. but my question is what would be an example of a non-threadsafe action? Struts manual said that only one instance of an action exists in the JVM.. and when I run an action each thread creates its own versions of all the variables within the action correct? So assuming I'm not accessing some outside 'global' variable, everything is inherintly threadsafe right? If anyone can give me an example of what 'not' to do that would help tremendously. thanks, David - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: struts, hibernate, datasources .... so lost
Rich I know how you feel. I just dealt with nearly the same problems the other day. I for the life of me could not get Hibernate to bind to my JNDI datasource.. so I bailed on that and in my hibernate.cfg.xml I just had it setup the datasource and manage it from there: hibernate-configuration session-factory name=salesweb:/hibernate/SessionFactory property name=dialectnet.sf.hibernate.dialect.MySQLDialect/property property name=show_sqltrue/property property name=connection.usernameuser/property property name=connection.passwordpass/property property name=connection.urljdbc:mysql://192.168.0.104:3306/salesweb/property property name=connection.driver_classcom.mysql.jdbc.Driver/property property name=use_outer_jointrue/property property name=transaction.factory_classnet.sf.hibernate.transaction.JDBCTransactio nFactory/property property name=dbcp.minIdle1/property /session-factory /hibernate-configuration etc. So what hibernate does when you build its config is load up a JNDI name and bind its session to that at salesweb:/hibernate/SessionFactory. Then I am using the hibernateFilter which the first run through will build that config and also store a static instance of the factory within that class. The reason its important to use the filter (to my understanding) is this: User requests a webpage, goes to struts action, action calls getSession() from the hibernatefilter, it binds that session to the current executing thread and ships it to the action. Action loads the requested items, perhaps the item has a collection that is loaded lazily, so it doesnt actually get loaded in the action. Action finishes and forwards to view (Note this is in the same thread!!), the view is a jsp that wants to render that lazily loaded collection. Well if you closed the session in your action this would fail. but because the session is still maintained until the request is fully finished it succeeds. Make sense?

I feel that what I'm doing is conceptually simple; yet I can't seem to actually implement any of it. I think I have a rudimentary understanding of how to integrate Hibernate into Struts, but I'm unsure on a few points. First the datasource. I'm trying to set up a default data source that all web applications can use. I use container based authentication and I want my realm to use it as well. Trolling these lists showed me a solution that does work with my realm (XML fragments follow below). But when I try to use that same datasource with Hibernate, my web application fails to load and I get the following error: SEVERE: Could not find datasource: java:comp/env/jdbc/prospectingDB javax.naming.NameNotFoundException: Name jdbc is not bound in this Context Here are the XML fragments from server.xml. First, I set up a global resource: GlobalNamingResources Resource name = jdbc/prospectingDB auth = Container scope = Shareable type = javax.sql.DataSource/ ResourceParams name=jdbc/prospectingDB ... Usual parameters go here Right under the engine tag I define my realm. This works for my container based auth Engine name=Catalina defaultHost=localhost debug=10 Realm className = org.apache.catalina.realm.DataSourceRealm debug = 99 dataSourceName = jdbc/prospectingDB userTable = auth_roles_view userNameCol= email userCredCol= pwd userRoleTable = auth_roles_view roleNameCol= role/ Then I set up a resource link in the default context: DefaultContext ResourceLink name = jdbc/prospectingDB global = jdbc/prospectingDB type = javax.sql.DataSource / /DefaultContext As I said, that all seems to work. But Hibernate bails: hibernate-configuration session-factory name=prospecting/hibernate/SessionFactory property name=connection.datasourcejava:comp/env/jdbc/prospectingDB/property property name=show_sqlfalse/property property name=dialectnet.sf.hibernate.dialect.PostgreSQLDialect/property mapping resource=Employee.hbm.xml/ /session-factory /hibernate-configuration I can't seem to figure out why. If I change the server.xml to define the datasource in my web-app context, then I get problems with container based authentication not finding the datasource?? ... and speaking of Hibernate, I think I figured out how to use the HibernatePlugIn. I use that to set-up a Hibernate session factory on web app instantiation. But what I'm not 100% sure on is why I need to set-up a filter to implement the open session in view pattern.

Re: struts, hibernate, datasources .... so lost
That code should work assuming your object is fully loaded by the time it
gets to the view and no longer needs the session. Also I would use
Transactions in your code even on simple query's.. that was the advice given
on hibernate's site. ie: Transaction tx = session.beginTransaction(). then
tx.commit() when done or rollback or whatever.
Also I don't know what you are using as your log manager but using log4j
when I get a hibernate error I also send it the exception and it prints a
stack trace for me which gives more information on what went wrong.
Can't say that I've seen that behavior with tomcat myself =).. I have a
whole other can of worms I've had to deal with involving that...

I think that makes sense. So basically you are saying I HAVE to
implement the filter and doing something like this:
try
{
Context ctx = new InitialContext();
SessionFactory sf =
(SessionFactory)ctx.lookup(prospecting/hibernate/SessionFactory);
Session session = sf.openSession();
Query query = session.createQuery(select e.pwd from
com.autorevenue.prospecting.hibernate.Employee e where e.email =
:email);
query.setString(email, email);
e = (Employee)query.uniqueResult();
if( e != null)
{
password = e.getPwd();
}
session.close();
}
catch(Exception exc)
{
servlet.log(Hibernate error + exc.getMessage());
}
Won't work??
I've made some progress, I think. Log output shows Hibernate is
returning a value for a given query but the code above keeps
throwing an exception that is simply Hibernate error null Perhaps I'm
getting that because I'm not using the filter yet?
Another frustrating thing is that my container based auth stopped
working. Keep getting Name jdbc is not bound in this Context. Have to
play with that some more.
Another weird thing. Copying a new war to the war directory and having
Tomcat reload my war doesn't seem to work anymore. I mean, it does load,
but when it does changes to the Hibernate config aren't updated. Only
way, so far, to see changes has been to shutdown server, deleted war
filed and war directory, copy new war file to webapp directory, and
restart. Does the same thing happen to anyone else?

The sessions essentially just a sort of Map. Access to it may be

associated with the same session will execute simultaneously.
If you have 1 threads playing with the same unsafe object (which you just

synchronise their access to it externally.
ie:

Not sure how OT this question is.
My current plan (unless this is bad for some reason, but if so, Ted H

a user into his httpSession, and reuse it on each request.
A Hibernate Session instance isn't threadsafe. I imagine if two really
quick http requests got generated out of the same browser, all hell
could break out.
I guess I want to know if mortals like me need to worry about this.
Does Struts (or the Servlet container FAIK) prevent this from occuring,
or do I need to ensure this doesn't happen? If so, how? With a token or
is there a better strategy?

That second one actually works great, 43.html. Since each request is
running in its own thread it has the possiblity to create a new hibernate
session for every request, but it only creates it if you call the getSession
method on the filter. And at the end of the request that session is
destroyed.

Synchronizing on the session object may cause you all sorts
of grief...or it may not. It all depends on your container.
The spec makes no guarantees about the identity of the object
returned by methods like PageContext.getSession or
HttpServletRequest.getSession. For example, here's a test JSP:
%@ page contentType=text/plain %
%
out.println(session: + session);
out.println(pageContext.getSession: +
pageContext.getSession());
out.println(request.getSession: +
request.getSession(false));
out.println(request.getSession: +
request.getSession(false));

Here's the output from TC 4.1.24:
session:

pageContext.getSession:
[EMAIL PROTECTED]
request.getSession:
[EMAIL PROTECTED]
request.getSession:

And that's just within the same thread! I'm pretty sure TC
4.1.29 does return the same instance, but just remember it's
not guaranteed.

There's nothing in the specs that guarantee threadsafe
access to
session attributes.
A pattern I've become quite fond of is to create a
single object
(we call it a shell, analogous to an operating system shell)
which encapsulates everything you want in session context for a
given user;
then put just this object into session scope, and use
methods on
it
to do everything else. This helps you apply
synchronization where
appropriate. There's still a risk of a race condition
involving the
initial creation of the shell (assuming you do something like
check
the session to see if there's a value under the key you
use for the
shell) -- you can put that in a block synchronized on
the session
object:
MyAppShell shell = null;
synchronized (session)
{
shell = (MyAppShell) session.getAttribute(SHELL_KEY);
if (shell == null)
{
shell = new MyAppShell ();
session.setAttribute(SHELL_KEY, shell);
}
}
If the shell concept seems like high overhead to you, you
can still
synchronize accesses on the session object along those
lines; you may
just have more trouble keeping track of all the places
it needs to
happen.

Well what that plugin does is IF you request a session from it, it binds a Hibernate Session to your current executing thread. thus if you are using actions, anywhere in that action and in the resulting jsp the same session is used if you requested it again. And on requests for images or whatever since its never requested it doesn't get created.

I'm pretty sure TC 4.1.29 does return the same instance, but just remember it's not guaranteed.

David, There is an alternative Struts/Hibernate/JNDI combination. All of it hinges on one file: hibernate.cfg.xml. It doesn't require any changes to server.xml or web.xml and works (at the very least) for me on Struts v1.0 v1.1 with Hibernate v2.0.3 V2.1beta6 under Tomcat 4.1.24 through 4.1.29. * Use a hibernate.cfg.xml file like so (passwords changed and pardon my MySQL slant) ?xml version='1.0' encoding='utf-8'? !DOCTYPE hibernate-configuration PUBLIC -//Hibernate/Hibernate Configuration DTD 2.0//EN http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd; hibernate-configuration session-factory name=dgf:/hibernate/SessionFactory property name=dialectnet.sf.hibernate.dialect.MySQLDialect/property property name=connection.usernameAA/property property name=connection.passwordBB/property property name=connection.urljdbc:mysql://localhost:3306/authors/property property name=connection.driver_classcom.mysql.jdbc.Driver/property property name=show_sqltrue/property property name=use_outer_jointrue/property property name=transaction.factory_classnet.sf.hibernate.transaction.JDBCTransactio nFactory/property property name=dbcp.minIdle1/property !-- Optional, I use this but it requires an opensymphony.org download of OSCache property name=cache.use_query_cachetrue/property property name=cache.provider_classnet.sf.hibernate.cache.OSCacheProvider/property -- !-- insert any mapping file so you don't need to hardcode adding classes or adding files in a Java class -- mapping resource=hibernate/Misc.hbm.xml/ /session-factory /hibernate-configuration The JNDI location is set in the session-factory tag using the 'name=' attribute. Whatever name you choose, DO NOT use anything starting java:comp/env as that is read-only in Tomcat and will NOT work. I made up a context named dgf:/hibernate/SessionFactory and was pleasantly surprised when hibernate created the context for me and stored the SessionFactory within it so I could us it in JNDI context lookups after I got the InitialContext and performed a ' SessionFactory sf = (SessionFactory) context.lookup(dgf:/hibernate/SessionFactory);'. I see you want to use DBCP. As long as you set a minimum of 1 dbcp property, hibernate will detect you want to use DBCP as your connection pool. Feel free to set more than one DBCP property or even to use something other than dbcp.minIdle as in my working example above. Hibernate can work with other connection pools. I recommend avoiding C3P0 as it can't shutdown (eats up memory unless you fully shutdown the JVM [i.e. TOMCAT] and restart). A Beta C3P0 allows shutdown of a C3P0 pool, but the last time I checked, the Hibernate controlling class for C3P0 pooling still had an empty finalize() and never actually shutdown my C3P0 pool.

Strategy for out of date items through forms using hibernate?
Hi I am using Struts with Hibernate in a webapplication.. we are using forms etc. The problem I am currently trying to decide how to handle is thus: Assume user 1 loads up an object in a form and is modifying it. Assume user 2 loads up the same object in a form and is also modifying it. User 1 submits the modified object. User 2 also submits the object, however his is out of date and I would like the webapp to tell him that and show the differences that exist. What is the best way to use hibernate to deal with this? What I have attempted is using the built in timestamp feature in MySQL, I have a field in my object that is timestamp but does not insert or update, thus mysql controls its value. Then when the user submits the object I loaded another copy of that object from the DB and tried to compare their dates.. however this gave me an error saying: net.sf.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: 1, of class: cmcflex.salesweb.model.prospect.Prospect because of the object I loaded to compare. What do do? Is there a better strategy for tackling this? I tried using the actual timestamp in the properties for my object, but then when I tried to submit the object the generated sql said when id=? AND timestamp=? meaning it would not update if the timestamp is different, and I'm unsure if I could even determine if it did or did not update.

Re: Strategy for out of date items through forms using hibernate?
I have done this. Hibernate supports versioning (using a version number column), if you use this Hibernate can make sure the changes are not overwritten. The basic process is: 1. Hibernate session A loads object A1 (with identifier 1234) 2. Hibernate session B loads object B1 (also with identifier 1234) 3. Session A modifies object A1 and saves it 4. B modifies object B1 and attempts to save it 5. Hibernate will detect the version number for the object has changed and generate an exception (StaleObjectStateException) 6. Catch this exception, close the hibernate session, return an error message to the user using ActionErrors etc I also have a refresh button so that at any time the user can press refresh which reloads the object from hibernate so it is up to date. When I return my stale object error I also allow the user to either refresh (loses the users changes), cancel (do nothing, return to parent menu), or overwrite. Overwrite can attempt to overwrite the changes by reloading the new object, but use the posted field changes to update and then save the object. Yes I figured this out just barely, rather I used timestamp instead of version (are there any drawbacks to that?). I am interested in doing exactly what you did, but how did you go about overwriting the things that have been changed?

I am working in an environment where we are mixing the two. My advice to you is to *not* do it. Pick one and use it as it was intended to be used. I personally prefer iBATIS. It is very simple; it plays well with existing databases; it allows you the flexibility, commodity and performance tuning of sql; it provides object wrappers for your data. All while staying in your DAO and out of your application. From my experience, if you are using hibernate, you write hibernate applications, not java applications that use hibernate - even if you try to wrap it so that it is not used directly. Trust me, we did. If you are willing to accept that, hibernate may work for you. Some other factors to consider: - How many developers know hql vs sql? - How much time will it take for a new person to learn the idiosyncrasies of the tool (and they both have them)?

named getForumGroup? How does struts determine what to call to just get a

Once again solved my own problem minutes after posting about it.. lol..
anyway for anyone else that searches this down the road.
It is ESSENTIAL in your form that your method for getting one element from
the list your iterating over matches your variable name in the jsp your
using or what not. Example:
logic:iterate name=userForm property=forumGroups id=forumGroup
trtd width=1%html-el:checkbox name=forumGroup property=available
indexed=true//td
td width=25% nowraphtml-el:hidden name=forumGroup property=id
indexed=true write=false/
html-el:hidden name=forumGroup property=name indexed=true
write=true//td
tdhtml-el:hidden name=forumGroup property=description indexed=true
write=true//td/tr
/logic:iterate
notice my arraylist is named forumGroups, and each object in that array is
assigned as forumGroup. Therefore my method in the form that takes the
index as its parameter to return that object from the arraylist MUST be
named getForumGroup(int index).

Yep, the same setup works in that situation - and the way Tomcat knows
to use the precompiled JSPs is that special entries for each of the
servlets generated from jasper (the JSP compiler) are entered into the
web.xml file (this, of course, can be automated).

Re: Eclipse + Ant + precompile - Tomcat
Ok I solved that question its looking for an exact directory. But now I'm
getting this error when trying to build:
java.lang.NoClassDefFoundError:
org/apache/xerces/impl/XMLNSDocumentScannerImpl$NSContentDispatcher
And I made sure that my path has the newest versions of the xerces jars...
any ideas?
Here is my build file
target name=jspc
delete dir=${WEB-INF.dir}/src/

pathelement location=${java.home}/../lib/tools.jar/

/taskdef
mkdir dir=${WEB-INF.dir}/src/
jasper2 validateXml=false
uriroot=c:\projects\salesweb\build
webXmlFragment=c:\projects\salesweb\uild\WEB-INF\generated_web.xml
outputDir=c:\projects\salesweb\uild\WEB-INF\src /
/target
the xerces jars are in eveyr one of the fileset include dirs.. what gives?

What values are expected to go into
jasper2 validateXml=false
uriroot=/salesweb
webXmlFragment=${WEB-INF.dir}/generated_web.xml
outputDir=${WEB-INF.dir}/src /
the uriroot, webXMLFragment, and outputDir? Are they the full path names

Yep, the same setup works in that situation - and the way Tomcat knows
to use the precompiled JSPs is that special entries for each of the
servlets generated from jasper (the JSP compiler) are entered into the
web.xml file (this, of course, can be automated).

Subject: Eclipse + Ant + precompile - Tomcat
I've been doing some googling on having a webapp precompiled when
deployed to Tomcat via an Ant task and I'm a bit intimidated with
what's
involved. Has anyone out there done this? Right now, I have an Ant
build
setup as an external build in Eclipse that does a variety of things,
including building, packing up my WAR, and installing this WAR to
Tomcat
using the catalina-ant install command that uses the management URL
and an external context file to install the webapp in a (local)
running
Tomcat instance.
I'd like to follow-up the install with a directive to Tomcat to
precompile the JSPs in the web application - does anyone have an Ant
task that I could adapt to this purpose that they'd be willing to
share?
Thanks!

Re: Tiles Redirect Bug on a per Tile basis? Help!
Adam,
Essentially I just want to display a different content in that area of my
layout. And I considered using a jsp:include, but by the point the logic
determines that a different page needs to be in that spot it has already
loaded a bunch of JSP variables and stuff into the page, by including
another page with variables potentially the same would it mess everything
up? Also for example was:
if (x condition is met)
{
%
jsp:include blah.jsp
%
return;
}
%
Would that return successfully quit running any logic from my original jsp?
Thanks,

These are my two tile definitions in my tiles-defs.xml file. I call a

%@ taglib uri=/WEB-INF/struts-tiles.tld prefix=tiles %
tiles:insert definition=.Forum flush=true
tiles:put name=body value=/forum/test-.jsp/
/tiles:insert
(which is basically just a way to call a definition without using a
struts
action for right now)
The above fills everything into our page layout and overrides body with
test-.jsp. Now test-.jsp goes into the body slot, the main area on the
page. I do some logic in it and determine, before its rendered, that
the
user is not logged in or whatever else, and instead of it going into the
body area it needs to redirect to another page to fill that slot.
However
when I try that the body area just comes up blank. And thats just
using:
url = response.encodeRedirectURL(request.getContextPath() +
/forum/transition.jsp);
response.sendRedirect(url);
return;
I know the above redirect code works, because when I put it in a .jsp
that
does not includes our tiles layout it works fine.
It's not clear whether you want to do a redirect to take the user to a
different page, which is what I assumed from your first message, or
whether you want to stay on that page and just have different content in
your body slot.
If you only need different content, why do a redirect? Why can't you
just do a straight jsp:include?

Re: Tiles Redirect Bug on a per Tile basis? Help!
Adam,
I agree with you.. I'm not a big fan of logic in jsps other than minimal
stuff, but in this circumstance we are retooling a jsp based forum and
eventually will port it to struts but at the moment time is scarce.
I was able to make it work using the jsp:include pageblah/ tag. I found
some interesting stuff with it though. The page url is relative to your
context. So if my context was /salesweb, and i wanted the page at
/salesweb/forum/transition-.jsp I would need to send it
/forum/transition-.jsp. Also when I tried jsp:include page%=
request.getContextPath() %/forum/transition-.jsp/ I would get a compile
error (this was before I figured out it was context relative), however
jsp:include page%= StringNameHere %/ would work. Very odd. I just
wish the original redirect would work, so my code doens't look all sloppy ;)
Thanks Adam,
David

Regarding the variables getting messed up: there are 2 types of includes
- I think the one you have used above would be OK. There is also the
straight @% include file= %. Again though JSP is not my forte.
I'm not sure whether the return would end the JSP. A check in the
compiled JSP file would show you. I never do too much logic in my JSPs
so I'm not too hot on that.
Perhaps you should make an else {} that encompasses the whole of the
rest of the JSP. Horrible, but I take it you are modifying existing
code, so it might be the easiest way.

That is a demanding question. The problem is that the outer-most Tile
controls its child Tiles. This is a complete stab in the dark but try
writing the redirect URL into the request attributes, and then at the
end of the outermost Tile, check to see if there is a non-null value,
and if so, do the redirect there.

Cannot redirect within Tiles?
Essentially I have a tile that includes a bunch of little jsps. Actually I am integrating Yazd messageboard into our app. But anyway it posts to itself (has the logic to do so) and if the post is successful it does a response.sendRedirect to another page instead of displaying itself again. Well I'm not getting any errors on it sending the redirect, but when the page loads its just empty in the spot where the redirected jsp should display.

Getting a url inputstream from within an action loses the session?
Hi everyone, I'm doing some xml and xsl transformations within one of my actions, and the action needs to get an inputstream or some type of reader on a url for the xml and xsl, however when I request those URLS it goes through our filter and gets denied because the request is somehow outside of the session scope of the logged in user! The code I was using : SAXSource saxSrc = new SAXSource(new InputSource(myUrl.openStream())); very simple.. our login management information is stored in the session, but when this url is requested on our system from within an action that session information does not propogate to the filter so when the filter checks the session for a user its not there.

log4j configuration question
A couple quick questions: 1) Using tomcat is it possible to configure log4j to only be functional for your particular webapp? Because I put the log4j jar into my web-inf/lib directory, built a log4j.properties and put it in /web-inf/classes and set log4j's rootlogger to debug and got log messages from tns of stuff that I certainly hadn't setup to log.. just wondering. 2) I'd like to keep my log files potentially in my /web-inf/logs directory, however how can I get a handle on the realpath to that directory from the config file if I don't know where the deployed path would be?! I'm assuming I'd have to do that programmatically after the config file loads and that could be a major PITA if there are lots of log files correct? Some help and guidance in this direction would be appreciated. -David - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

To further clarify what seems to be my problem. Display action sets begRecord and endRecord attributes in the request - JSP renders a form - submitted form goes to Modify Action - modify action tries to put something in begRecord and endRecord, appears to be ok - forwards to display action, display action sees the same values in its request object that were originally set by itself earlier.

The usage of the Tiles Controller Actions are essentially to perform logic on a per tile basis.. so yes you could have a TilesAction for each of your tiles and inside each it could query the database, get the required information and push it into the tiles context, from which your jsp could get that data and display it. -David - Original Message - From: Barry Volpe [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Tuesday, September 16, 2003 4:46 PM Subject: Dynamic links, Tiles and Actions Let's say I have several groups of links grouped as tiles. The displayed links will be dynamic based on the current state of the database. I have read what may be a possible solution: Tiles Controller feature here is an article: http://www.theserverside.com/resources/article.jsp?l=Tiles101 If I am understanding correctly it would not be good practice to query the database (Mysql by the way) directly from my JSP. (Not sure how to do this anyway - tags etc). Could I use multiple forms (with an action for each) on one JSP? What is the common solution? Having a page which may for example have several form controls and links that require querying the database and would be dynamic? Several queries will be required to be performed at the same time for one jsp view. Thanks, Barry - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Struts Tag Question
Here is the code I'm trying to get to work:
html-el:link
href=javascript:Start(${indexedBean.id})test/html-el:link/
but what I need are double quotes around the ${indexedBean.id} part. I've
tried using both quot; and \ both seem to not work because the link ends
up stopping at wherever I insert that at.. for example if I try:
html-el:link
href=javascript:Start(\${indexedBean.id})test/html-el:link
the link when moused over shows: javascript:Start(
same thing if I try quot; instead of \
any ideas?

Re: Problem with Checkboxes using logic:iterate
I am assuming you are using this form in a session scope then.. check back through the archives on the reset function of the form there have been numerous posts within the last few weeks on this topic.. Essentially what happens is that if you deselect a checkbox and then submit the form, nothing is submitted for that checkbox, the only values that are submitted are when the checkbox is clicked and it submits true or on or whatever you tell it to submit. If the form is request scope its already gone and the values are initialized to blank anyway so its no problem. But in Session youll typically have to work with the reset function of the form..

Quick Java question..
Hey as I've been building my actions I was thinking it could be useful for me to have a method that does some database querying, but I would like to give the user the ability to narrow down that query with as many input fields as he needs. Is there a way to write a method that takes a non-set amount of arguments? (Other than just passing the method a growable array.. which is a viable alternative) Ie public String myfunction(String a, String b, String c on down the line indefinitly) ? I thought I had seen this done somewhere somehow but I may be wrong. Thanks! - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

The problem is I need a seperate tiles definition for every possible menu configuration, and then if I want an action that forwards to a definition that could show different menus.. etc etc it gets to be a pain. So would it be possible to change whats in that list or add to that list in my action before I forward to a tiles def? *Shrug just trying to get some ideas together here*. If that is not possible then my next question is in my baselayout.jsp I have the tiles:insert attribute=menu/ tag. In which scope does it search for a variable named menu? and if i changed that to tiles:insert attribute=$menu/ or something of that nature could it change at runtime based on something in my request/or session scope?

Re: html:checkbox, iterate and a value
Here's how I'm doing it:
table border=3 bordercolor=#323299
trtd/tdtdPermission/tdtdDescription/td
html-el:form action=/saveuser.do?user=${requestScope.userid}
type=salesweb.EditUserForm
logic:iterate name=edituserForm property=indexedBeans
id=indexedBean
trtdhtml:checkbox name=indexedBean property=available
indexed=true//td
tdhtml-el:text name=indexedBean property=id indexed=true
readonly=true//td
tdbean:write name=indexedBean property=description//td/tr
/logic:iterate
/table
My form contains a getter for indexedBeans that returns an ArrayList, and it
iterates through each item of that storing my custom bean in indexedBean.
IndexedBean has getters and setters for available, id, description. My
action that forwards to this jsp prepopulates all the items.. if oyu want
the checkbox to be checked on viewing the property must be set to on yes
or one other indicating yes, if you want it to be set to off just leave it
blank. When the form is submitted if its not checked it submits no value at
all.

Subject: html:checkbox, iterate and a value
What is the proper way to build html:checkbox's inside of an
logic:iterate loop?
It seems that the html:checkbox's value parameter can't reference a
property from the bean of the iterate loop.
I have something close to:
logic:iterate id=myItem name=myData type=...MyData indexId=index
...
html:checkbox indexed=true property=uniqueKey name=myItem/
...
html:link action=MyViewItemsAction
paramId=myId
paramName=myItem
paramProperty=uniqueKey
bean:write name=myItem property=uniqueKey/
/html:link
...
The html:link works great. I just don't know how to achieve the same
for the checkbox. What I get sent is:
myItem[0].uniqueKey=on
myItem[1].uniqueKey=on
myItem[2].uniqueKey=on
Not much of a help. I really need the value of that uniqueKey to be the
value of the checkbox.
Any help steering me in the right direction would be appreciated.
Thanks!

I was thinking it had something to do with this function:
public PermissionLine getIndexedBeans(int index) {
System.out.println(Index Requested: + index + Size of Array: +
this.myBeans.size());
while (index = this.myBeans.size())
this.myBeans.add(new PermissionLine());
return (PermissionLine) this.myBeans.get(index);
}
But i through that debugging code in there and it never gets output at all..
so it must be something to do with the populate function on copying getters
and setters from the form to the bean, but its the exact same bean i used to
populate it with, doesnt make any sense.. anyone got any ideas?

Dynamic Form help
I'm developing some administrative functions for our web app, currently im working on a page where it will list all the permissions available with a checkbox by each, and the ones the current user has will be checked. I'm trying to decide the best way to go about it, becaues the permissions are pulled from a database and so they could change everytime the page is loaded, and obviously every user will have different permissions which need to be checked. It shouldnt be a problem to iterate through a list of permissions, but the question I have is when I go to submit a the form to modify the users permissions, the names of each checkbox (permission) will change, so how would I develop a form to handle that? And is there an easy way to populate all the checkboxes when the page loads? I'm using JSP's to handle it.. would love to use struts html:XXX tags if possible. Reccomendations welcome =) Thanks - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
