[jboss-user] [JBoss Seam] - Seam PDF with content-disposition=attachment - is it possibl
Currently, when I generate PDFs using Seam PDF, they either a) open in the same browser window by default, or b) open in a new window, if I use s:link with target=_blank. What I'm missing (compared to the old way of generating PDFs using Jasper - not that I miss Jasper by any amount) is the ability to force a save dialog to pop up when a PDF is requested, by setting content-disposition: attachment in the response. Now, my question is, was this ever addressed by Seam? Is it possible to force a save dialog when generating PDF using Seam PDF? Alternatively, is it possible to get the generated PDF as a byte[] in the code - so that I would output it manually, setting the content-disposition on the way?

[jboss-user] [JBoss Seam] - EntityQuery.resultList contains all nulls after AJAX request
This one drives me crazy! If there's a list box backed by an EntityQuery, on
the same page with an AJAX component (in my case it's RichFaces
DataScroller/DataTable), then after several AJAX requests, the resultList for
EntityQuery contains a list of nulls. It looks like every entity in the
resultList is replaced with a null. I'm not sure whether it's Seam or
RichFaces, but it's bound to be one or the other.
Anyway, here's the setup: Seam 2 GA, RichFaces 3.1.2, Facelets 1.1.14, JSF RI
1.2.05, Hibernate 3.2.5 GA.
The entites A and B are identical in structure (though they can be different,
for as much as this bug cares):
@Entity
| public class A implements Serializable {
| @Id
| private String name;
|
| public String getName() {
| return name;
| }
| }
The EntityQuery's:
core:init debug=false /
| core:manager conversation-timeout=12
concurrent-request-timeout=500 /
| persistence:entity-manager-factory name=testDatabase /
| persistence:managed-persistence-context name=entityManager
| entity-manager-factory=#{testDatabase} auto-create=true /
| transaction:entity-transaction entity-manager=#{entityManager} /
| framework:entity-query name=listOfA scope=conversation ejbql=FROM
A a order=name /
| framework:entity-query name=listOfB scope=conversation ejbql=FROM
B b order=name /
| security:identity authenticate-method=#{authenticator.authenticate}
/
| web:ajax4jsf-filter force-parser=false enable-cache=true
class=org.ajax4jsf.FastFilter /
Now, the Facelets page:
h:form xmlns=http://www.w3.org/1999/xhtml;
| xmlns:h=http://java.sun.com/jsf/html;
xmlns:f=http://java.sun.com/jsf/core;
| xmlns:s=http://jboss.com/products/seam/taglib;
xmlns:r=http://richfaces.org/rich;
| r:dataTable id=list var=a value=#{listOfA.resultList} rows=4
| r:column
| h:commandLink action=Dummy value=#{a.name} /
| /r:column
| /r:dataTable
| r:datascroller align=left maxPages=1 for=list
fastControls=auto /
| br /
| h:selectOneMenu value=#{notImportantHere}
| s:selectItems value=#{listOfB.resultList} var=b
label=#{b.name} noSelectionLabel=Select one... /
| s:convertEntity /
| /h:selectOneMenu
| /h:form
Pretty simple - there's a scrollable datatable for entity A, and a dropdown for
entity B. Now, when user activates the datascroller twice, and then selects an
A from the data table, the list of Bs is empty - it contains the same # of
entries as before, but they are all empty.
Has anyone ever encountered such behavior before? Is this a bug? I myself have
seen it before, with a different AJAX component (it was a RichFaces suggestion
box that time), but dismissed it on the notion that what else could you expect
from a beta (Seam was B2 at the time)?
Thanks in advance,
Alex

@Name (scheduler)

| @Startup
| public class Scheduler {
| @In
| private IService service;

| // set in seam.properties via scheduler.reminderCron

| @Create
| public void startJobs() {
| log.info(Reminder task started on #0, cron schedule is #1,
| new Date(), reminderCron);
| service.sendReminders(reminderCron);
| }
| }
public interface IService extends Serializable {
| void sendReminders(String cron); // other methods are omitted
| }
@Name (service)
| @Scope (ScopeType.CONVERSATION)
| @AutoCreate
| @Transactional
| public class Service implements IService {
| @Asynchronous
| public void sendReminders(@IntervalCron String cron) {
| log.info(Reminder task activated on #0, new Date());
| // plus whatever other functionality you need here...
| }
| }
|
The scheduler starts with the app, and runs every morning (as per cron
expression, which you can change as needed)

[jboss-user] [JBoss Seam] - Re: 2.0.0 CR2 is out
There are a few problems with this release (as far as Maven is concerned, anyway): 1. Jboss-EL is still CR1 - have there been any changes to it as part of CR2? 2. Source JARs have incorrect naming - there's an extra dash in there that makes them unrecognizable to Maven(jboss-seam-2.0.0.CR2--sources.jar vs expected jboss-seam-2.0.0.CR2-sources.jar) 3. Seam UI declares a hard dependency on JSP-API, which makes absolutely no sense if Facelets are used. Shouldn't that one be declared as provided, just like JSF RI does it? Other than that, thanks for the good work!

Just make the changes yourself, then (you did read the bug report details,

Grab MenuRenderer from the latest RI release.
Scroll to the end of renderOption method, and change the following code block
if (curItem.isEscape()) {
| String label = curItem.getLabel();
| if (label == null) {
| label = curItem.getValue().toString();
| }
| writer.writeText(label, component, label);
| } else {
| writer.write(curItem.getLabel());
| }
| to this one: if (curItem.isEscape()) {
| String label = curItem.getLabel();
| if (label == null) {
| label = valueString;
| }
| writer.writeText(label, component, label);
| } else {
| writer.write(curItem.getLabel());
| }
|
Include the changed file in your web project (mind the correct package name),
this should automatically place the compiled class into WEB-INF/classes.

Yes, this sounds about right (though I never used seam-gen, so I have no idea about the structures it creates). Overriding a class is trivial - just include the correct version in WEB-INF/classes, this will override the JAR version. To be on the safe side, you might as well open the JAR with any ZIP program (WinZip, WinRAR, etc.) and delete the old class version. Is this a web (WAR) project you have, or a full-blown EAR?

vincent.latombe wrote : AFAIK, outjection is done after each call of each
method of a component.
Yes, if there's a method call - but what if there isn't one?
My use case is pretty simple, actually: there's an entity X, with an User
attribute, so that each user can see their own Xs, while an admin can see all
of them (optionally filtetred by user). Thus, there's an EntityQuery set up
(FROM X x) with restrictions in the form of x.user = #{selectedUser}, where
selectedUser is outjected. Admin screen either outjects null (default on page
load) or the user that list should be filtered on (via method call in admin
screen controller). User screen, OTOH, is to automatically outject the current
logged in user as selectedUser. To accomplish this, the controller bean for
user screen declares @In @Out (selectedUser) User principal; (principal is
the current logged in user, outjected into session on login).
The only problem is, there's no way to control which of the controller beans
would outject the value first (on first page load, for instance). The hacker
way to solve this is to introduce a no-op method in each of the controllers,
that would execute on page load and do all the outjection, like that: page
view-id=/attestation/accounts.xhtml
| action=#{accountController.noOp} /, but of course this is
just a hack...

[jboss-user] [JBoss Seam] - Re: Multiple beans outjecting same variable - how to control
No, still doesn't work - if I add the factory only to the user controller, then admin controller uses it as well, as it's the only one defined (filtering where it shouldn't), and if I add one to admin as well (returning null, of course), then user controller uses that one, too... So I guess I'm back to the no-op method, which seem to be the only working here :( Anyway, thanks for help. I guess it would be nice to be able to specify a default resolver for a page (in pages.xml), so that on page load, a particular bean would handle all outjection - what do you think, is this a sensible way to handle such situation?

If you're using plain JPA (no EJB3) and you don't require JTA, then no, you
don't need jboss-embedded at all. You'll need to
a) use Seam transaction manager transaction:entity-transaction
entity-manager=#{entityManager} /
b) declare your datasource in Tomcat
c) reference the datasource in persistence.xml, and make sure to specify
transaction-type=RESOURCE_LOCAL
If you need any more info, just ask (but make sure to read the docs first, it's
all explained in detail there)

Looks like I mixed up the two. It's the validateAll that I used (with s:decorate, as per Seam examples), and yes, it now works with s:validate - thanks. Now, I take it, there's no way to incorporate s:validate in s:decorate template (as it goes inside the input field), is there? :( View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=4074190#4074190 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=4074190 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

You should be able to make it working without using the data model, or at least I was able to. Try placing the trackList (it's an EntityQuery, right?) inside a long-running conversation, as it might be that, by the time the playMediaId() is called, the trackList is already expired, so track.id would evaluate to null. Then again, it's all pure guesswork, it would help to see more configuration than that...

Page- or event-scoped query would be recreated (and reexecuted) for each and every action performed on the page, including record navigation/selection. My idea was to minimize database hits by caching the queried list in conversation scope, only updating it when I know its state would change, i.e. when a record gets updated/inserted/deleted.

[jboss-user] [JBoss Seam] - Re: EntityQuery.refresh() doesn't clear the result list??
I must add - sometimes the queried list would get quite big (say, if it were the audit record that were queried, it might be measured in millions of records), so it would be lazy-paged in this case, and re-executing such queries on every page action wouldn't be a good idea...

[jboss-user] [JBoss Seam] - Re: EntityQuery.refresh() doesn't clear the result list??
First, thanks for the pointers. I'll look up the after transaction event in
the CVS. It must have been a freshly added one, as it's not listed in the Seam
2B docs... yet.
Now, in regards to anonymous wrote : How about using your debugger to find out
why ? Sheesh! where did I say that I didn't use one? Just tried to spare
everyone the gory details, as my concern was mainly whether I use the
components in a correct way - but since you asked, here goes...
To trace the problem, I used a modified EntityQuery class, with some logging
added to the methods that manipulate resultList. Only modified methods are
shown for brewity.
package org.jboss.seam.framework;
| public class EntityQuery extends QueryEntityManager {
| private static final Log log = LogFactory.getLog(EntityQuery.class);
| private List resultList;
|
| private void initResultList() {
| log.warn(Entered initResultList(), ejbql + getEjbql()
| + , hashcode + this.hashCode() + , list
size
| + (resultList == null ? null :
resultList.size()));
| if (resultList == null) {
| javax.persistence.Query query = createQuery();
| resultList = query == null ? null :
query.getResultList();
| }
| log.warn(Exited initResultList(), ejbql + getEjbql() + ,
hashcode
| + this.hashCode() + , list size
| + (resultList == null ? null :
resultList.size()));
| }
| @Transactional
| @Override
| public List getResultList() {
| log.warn(Entered getResultList(), ejbql + getEjbql() + ,
hashcode
| + this.hashCode() + , list size
| + (resultList == null ? null :
resultList.size()));
| if (isAnyParameterDirty()) {
| refresh();
| }
| initResultList();
| try {
| return truncResultList(resultList);
| } finally {
| log.warn(Exited getResultList(), ejbql + getEjbql()
| + , hashcode + this.hashCode() + ,
list size
| + (resultList == null ? null :
resultList.size()));
| }
| }
| @Override
| @Transactional
| public boolean isNextExists() {
| log.warn(Entered isNextExists(), ejbql + getEjbql() + ,
hashcode
| + this.hashCode() + , list size
| + (resultList == null ? null :
resultList.size()));
| return resultList != null resultList.size()
getMaxResults();
| }
| @Override
| public void refresh() {
| log.warn(Entered refresh(), ejbql + getEjbql() + , hashcode
| + this.hashCode() + , list size
| + (resultList == null ? null :
resultList.size()));
| super.refresh();
| resultCount = null;
| resultList = null;
| singleResult = null;
| log.warn(Exited refresh(), ejbql + getEjbql() + , hashcode
| + this.hashCode() + , list size
| + (resultList == null ? null :
resultList.size()));
| }
| }
And here's the log output during the execution of controller's save() method
for a new record:
WARN [org.jboss.seam.framework.EntityQuery] - Entered refresh(), ejbql FROM
Account WHERE closed = false AND familyExemption = false AND user =
#{principal}, hashcode 10610605, list size 5
| WARN [org.jboss.seam.framework.EntityQuery] - Exited refresh(), ejbql FROM
Account WHERE closed = false AND familyExemption = false AND user =
#{principal}, hashcode 10610605, list size null
| WARN [org.jboss.seam.framework.EntityQuery] - Entered getResultList(),
ejbql FROM Account WHERE closed = false AND familyExemption = false AND user =
#{principal}, hashcode 10610605, list size 5
| WARN [org.jboss.seam.framework.EntityQuery] - Entered initResultList(),
ejbql FROM Account WHERE closed = false AND familyExemption = false AND user =
#{principal}, hashcode 10610605, list size 5
ejbql and hashcode output is mainly to make sure we're dealing with the right
query, and that it stays the same object during execution (i.e., not dropped
and re-created).
As you can see, refresh() resets the resultList to null all right, yet the next
time query gets accessed, it still contains the same old result list (refreshed
one would contain 6 items, as one was added)! There are no modifications to
resultList in between these calls, as evident from both the logs, and from the
breakpoints I've been placing. My suspicions were at the javassist, that with
the bytecode enhancement on
[jboss-user] [JBoss Seam] - Re: EntityQuery.refresh() doesn't clear the result list??
Thanks for your help Gavin.
There's a manual flush right before the refresh() call:
public void save() {
| em.persist(selectedAccount);
| em.flush();
| selectedAccount = null;
| userAccounts.refresh();
| }
and the data does indeed get into the database. Here's the same log, this time
with SQL logging included:
WARN [org.jboss.seam.framework.EntityQuery] - before em.persist()
| Hibernate: select SEQ_ACCOUNT.nextval from dual
| WARN [org.jboss.seam.framework.EntityQuery] - before em.flush()

| WARN [org.jboss.seam.framework.EntityQuery] - before refresh()

| WARN [org.jboss.seam.framework.EntityQuery] - Exited refresh(), ejbql FROM
Account WHERE closed = false AND familyExemption = false AND user =

| WARN [org.jboss.seam.framework.EntityQuery] - after refresh()

|
But that's not even what baffles me. If resultList was set to null, it would
have to be refreshed from the query. Now, where's the SELECT that refreshes the
list? As you see, no SQL SELECT is logged between the places where resultList
is null and where it's 5 items long again!
I'm suspecting that one of the interceptors resets the query state to what it
was before the save() call - but again, it must be doing it in a way that my
debugger doesn't catch. At least, the variable modification breakpoint in
Eclipse doesn't catch that update.
I'll try it with the after transaction event, to see if it makes any
difference, but still, it does look strange...

[jboss-user] [JBoss Seam] - Re: EntityQuery.refresh() doesn't clear the result list??
Nope, raiseAfterTransactionSuccessEvent() didn't help. Here's the code I used:
@Observer (refreshAccounts)
| public void refresh() {
| userAccounts.refresh();
| }
| @Transactional
| public void save() {
| em.persist(selectedAccount);
| em.flush();
| selectedAccount = null;
|
Events.instance().raiseTransactionSuccessEvent(refreshAccounts);
| }
and the result is exactly the same, both behavior-wise and log-wise.
Now, the EntityQuery is declared as @In private EntityQuery userAccounts; -
does it also need to be outjected if I change its internals, for the change to
take effect?

[jboss-user] [JBoss Seam] - EntityQuery.refresh() doesn't clear the result list??
Not sure whether it's a bug, or just me, but it doesn't look like the refresh()
method is doing anything for me - the result list is stale and never refreshes,
until I start a new coversation...
I have a simple CRUD screen where the edit form is combined with the record
listing:
h:form id=listForm styleClass=form
| ui:repeat var=transaction value=#{userTransactions.resultList}
| h:commandLink
action=#{transactionController.select(transaction)}
value=#{transaction.account.accountNumber} /
| /ui:repeat
| h:commandButton action=#{transactionController.create} value=Add
New /
| /h:form
| h:form id=rowForm styleClass=form rendered=#{not empty
selectedTransaction}
| !-- form fields go here --
| h:commandButton action=#{transactionController.save} value=Save /
| h:commandButton action=#{transactionController.remove}
value=Remove immediate=true rendered=#{not selectedTransaction.new} /
| h:commandButton action=#{transactionController.cancel} value=Close
immediate=true /
| /h:form
The query for record listing is an EntityQuery defined in components.xml:
framework:entity-query name=userTransactions scope=conversation
order=transactionDate, securityName
| framework:ejbql
| FROM Transaction
| WHERE user = #{principal}
| /framework:ejbql
| /framework:entity-query
and the controller code has the EntityQuery injected, and refreshes the list as
necessary:
@Name (transactionController)
| @Scope (ScopeType.CONVERSATION)
| public class TransactionController extends BaseController {
| @Out (required = false)
| private Transaction selectedTransaction;
| @Inprivate EntityQuery userTransactions;
|
| public void cancel() {
| selectedTransaction = null;
| }
| public void create() {
| selectedTransaction = new Transaction();
| }
| @Transactional
| public void remove() {
| em.remove(selectedTransaction);
| em.flush();
| selectedTransaction = null;userTransactions.refresh();
| }
| @Transactional
| public void save() {
| em.persist(selectedTransaction);
| em.flush();
| selectedTransaction = null;userTransactions.refresh();
| }
| public void select(Transaction transaction) {
| selectedTransaction = transaction;
| }
| }
The whole thing runs in a long conversation, started when the page is entered:
page view-id=/attestation/transactions.xhtml
| begin-conversation flush-mode=manual join=true /
| /page
Now, any time a new record is inserted, or an old one removed, the list should
refresh, shouldn't it? It doesn't, and I'm running out of any ideas on to why
would this happen... Help, anyone?
Thanks,
Alex

[jboss-user] [JBoss Seam] - BaseSeamTest - unnecessary depencency on JBoss Embedded?
I noticed that the org.jboss.seam.mock.BaseSeamTest has some references to what
it seems to be JBoss Embedded:
import org.jboss.deployers.spi.DeploymentException;
| import org.jboss.embedded.Bootstrap;
| snip
|protected void startJbossEmbeddedIfNecessary() throws
DeploymentException, IOException {
| if ( !started ) {
| Bootstrap bootstrap = Bootstrap.getInstance();
| bootstrap.bootstrap();
| snip
| }
|}
Is this intentional? As a result, SeamTest refuses to start (throws
ClassNotFoundException) unless JBoss Embedded is present. When I removed the
above method, SeamTest executed normally in a standalone environment, so
there's no real dependency there.

Given that we're stuck here with Tomcat anyways, I'd say it doesn't make much sense to use JBE for tests if it's not used in production (and if it is capable of running standalone - which it is), so, yes, if that dependency could be reworked into a soft one, that would greatly help...

Yes, and I declare it in persistence.xml, via hibernate.* properties.

[jboss-user] [JBoss Seam] - Re: s:decorate vs ui:decorate - different behavior for multi
One idea on how this might be fixed - allow s:decorate to take for attribute, that would be used to identify the input field, if one is not provided within the tag body. That way, users can decorate the label without the field (most common case in forms, IMO) without losing the ability to AJAXify the thing.

[jboss-user] [JBoss Seam] - Re: While Seam is great, is any weakness of this framework?
The only complaint I have about Seam so far, is the recommended packaging for Tomcat. The Microcontainer-based packaging places very serious restrictions on the application (for example, try passing the Tomcat-configured DataSource into the MC-based app) that makes this configuration not acceptable for production environments, leaving us Tomcat users feeling like second-class citizens. There are alternatives (using a JTA implementation), but they are not documented anywhere, so whoever decides to take this route is basically on their own (it took me awhile to get my environment running). Heck, some of the open-source JTA implementations are even coming from JBoss itself (JBoss Transactions), so why not dump the MC abomination altogether and use JBoss JTA/JCA modules directly, instead?

[jboss-user] [JBoss Seam] - Re: While Seam is great, is any weakness of this framework?
Because we're a major bank where everyone cannot run whatever they please. There are tons of regulations regarding what is allowed to run production environments. There's an architectural department that makes such decisions for a few years ahead. There are administrators that are hired with specific skill sets. But, yes, I guess I'll simply go to our production admins and say Hey, why aren't you willing to just download JBoss AS for free and use the embedded Tomcat?. Yes, that suddenly seems a terribly good idea... Seriously though, we here have WebSphere for mission-critical apps (no, I don't want to go into argument why are we using it), plus Tomcat for everything else that doesn't require a full-blown appserver. Tomcat administration is order of magnitude simpler than it is for an appserver, so, in the long run, these guys are saving a good money on support costs, both hardware and salaries.

You missed the point. Yes, time was spent integrating Seam with plain JTA and Tomcat (and I don't regret it), but I don't see why Seam documentation and examples shouldn't incorporate these findings.

My integration covers JOTM, Atomikos and JBoss Transactions (Arjuna JTA) - frankly, I hoped that the integration with the latter one would generate some more attention from JBoss crowd, that being a JBoss product and such. I also tried to explore integration with the JTA/JCA taken from the JBoss AS, but couldn't find any documentation on these modules (heck, even Javadoc is a pain to find!)

Is it possible to declare an @In property in an (abstract) superclass, but allow subclasses to configure the actual component name that gets injected? Currently, the only way I found was to declare an abstract String getComponentName() in superclass, and retrieve the query via Component.getInstance(getComponentName()) instead of @In declaration - but I consider this way to be rather ugly. Are there any alternatives, or maybe some planned enhancements?

[jboss-user] [JBoss Seam] - Re: @In with configurable component name - is it possible?
My main concern with your approach is that the whole @In semantics gets lost
from the parent class, even though it clearly belongs there. I was thinking of
something like an @Override annotation that would look something like:
public class Parent {
| @In private Foo foo;
| }
|
| @Override (
| property = foo,
| overrides = {
| @In (specificFoo)
| })
| public class Child {
| }
I found that it's possible to do the overriding in XML, but that's static DI,
not bijection. I'll try making foo a Seam's ValueBinding, maybe that would
result in true bijected foo...

[jboss-user] [JBoss Seam] - Re: @In with configurable component name - is it possible?
Well, if it's the parent class that (exclusively) makes the use of foo, then I guess it makes sense to contain the foo declaration in parent class as much as possible. The only thing that child class does is wiring - specifying what component gets injected into foo. Regardign the second point - yes, it does look complicated in this particular case. Yet, the generic way of overriding annotations in class hierarchy (something that Java currently lacks on the language level, IMHO) might get useful in some situations, even if it's not going to be an often-used feature.

Umm... I'd rather post it here, you can copy it later to Wiki if you know how
to do it ... as I don't :(
Note: each of the JTA implementations used has its own problems: JOTM doesn't
automatically shutdown with Tomcat; Atomikos has its own log framework that is
a pain to configure (they promised to migrate to log4j/CL though); and JBoss Tx
doesn't seem to have a way to configure XA-aware datasources (I've asked for
help on their forum, waiting for answers). Nevertheless, all of them allow to
start up Seam without the Microcontainer (that's 3.5Mb of JARs and a bunch of
nasty restrictions, mind you...). All that is needed is the Tomcat's standard
META-INF/context.xml file (or use server.xml if you prefer), some declarations
in META-INF/persistence.xml file, plus some glue code and some property files.
JOTM setup (http://jotm.objectweb.org/):
context.xml:
?xml version=1.0 encoding=UTF-8?
| Context

JOTM is the only one that doesn't need any glue code, as all the necessary
factories (Hibernate TM lookup, UT factory, and XA DataSource factory) are
already in place.

jta.properties (place in classpath):
com.atomikos.icatch.service=com.atomikos.icatch.standalone.UserTransactionServiceFactory
Atomikos needs one piece of glue code, and that is to look up the
UserTransaction properly. The developers promised to create the lookup class in
later versions, but for now, use this:
public class AtomikosUTLookup implements ObjectFactory {
| public AtomikosUTLookup() {
| }
| public Object getObjectInstance(Object obj, Name name, Context nameCtx,
| Hashtable environment) throws Exception {
| return new UserTransactionImp();
| }
| }

[jboss-user] [JBoss Seam] - Re: Possible bug - POJO doesn't automatically join transacti
Ok, thanks for the clarification. So, as I understand it, managed transactions give me a transaction around the method, and managed PCs give me an injected EM - but this doesn't mean that the EM automatically joins the transaction? Searched the reference docs, but haven't found any mention on whether it works one way or the other... Still, the fact that it only breaks for transient entities and not for managed ones, is hard to explain (for me, anyway). Also, it only breaks when the @Out annotation is present, which makes it even more strange.

[jboss-user] [JBoss Seam] - Possible bug - POJO doesn't automatically join transaction
Environment: Tomcat 5.5 + Seam 2.1.0 + Microcontainer, Seam-managed
transactions and PCs.
UserBean.java - displays a list of existing User records, allowing user to
select one (a-la clickable lists example) and edit it, or to create a new
record:
@Name (userBean)
| @Scope (ScopeType.CONVERSATION)
| @Transactional
| public class UserBean extends EntityController {
| @DataModelSelection
| @Out (required = false)
| private User selectedUser;
| @DataModel
| private ListUser users;
|
| public void addUser() {
| selectedUser = new User();
| }
| public void cancelEdit() {
| selectedUser = null;
| }
| @Factory (users)
| @Begin (flushMode = FlushModeType.MANUAL)
| public void createRecords() {
| users = createQuery(SELECT u FROM User u).getResultList();
| }
| public void saveUser() {
| // getEntityManager().joinTransaction();
| persist(selectedUser);
| flush();
| addFacesMessage(User #{selectedUser.username} succesfully
saved);
| createRecords();
| }
| public void selectUser() {
| }
| }
|
When executing saveUser(), if selectedUser is a transient (new) instance, the
flush() call throws a javax.persistence.TransactionRequiredException: no
transaction is in progress. If the first line is uncommented, the save
completes successfully (verified in DB). When selectedUser is a managed
(existing) instance, the updates complete successfully whether the first line
is commented or not.
Is this a bug? Am I using the bean in a correct way?
Thanks,
Alex

[jboss-user] [JBoss Seam] - Large Data Tables in Seam - feedback welcome
This is my take at the way to manage large datasets in @DataModel, without
loading them all in memory. Hopefully, this code will be of use to others
and/or generate useful improvement suggestions. Anyway, here goes:
LazyList.java - implements List interface, allowing its use in @DataModel. Only
holds one page (size can be configured) worth of data, delegating the actual
retrieval to the fetcher interface. Knows the total amount of data, again by
calling the appropriate method in fetcher.
public class LazyListT implements ListT {
| public static final int DEFAULT_PAGE_SIZE = 20;
| private int currentPage;
| private ListT dataset;
| private int datasetSize;
| private IFetcherT fetcher;
| private int pageSize = DEFAULT_PAGE_SIZE;
|
| public LazyList(IFetcherT fetcher) {
| this.fetcher = fetcher;
| datasetSize = fetcher.getDatasetSize();
| currentPage = 0;
| }
| public LazyList(IFetcherT fetcher, int pageSize) {
| this(fetcher);
| this.pageSize = pageSize;
| }
| public T get(int index) {
| int requestedPage = index / pageSize;
| if (index 0 || index datasetSize) {
| throw new IndexOutOfBoundsException();
| }
| if (dataset == null || currentPage != requestedPage) {
| currentPage = requestedPage;
| dataset = fetcher.getDatasetPage(currentPage *
pageSize, pageSize);
| }
| return dataset.get(index % pageSize);
| }
| public boolean isEmpty() {
| return datasetSize == 0;
| }
| public int size() {
| return datasetSize;
| }
| // the rest of the interface methods {
| throw new UnsupportedOperationException(Not implemented);
| }
| }
|
IFetcher.java:
public interface IFetcherT {
| /** Fetch a page of data */
| ListT getDatasetPage(int start, int pageSize);
| /** Fetch total dataset size */
| int getDatasetSize();
| }
|
CriteriaFetcher.java - implemets fetcher interface via Hibernate criteria
calls. Hibernate Session is injected via Seam, the criteria properties neeed to
be specified during fetcher construction (cannot be placed in constructor as
Seam needs a no-arg one). Criterias are used because sorting and filtering can
easily be added to them.
@Name (fetcher)
| @Scope (ScopeType.CONVERSATION)
| public class CriteriaFetcherT implements IFetcherT, Serializable {
| @Logger
| private static Log log;
| private DetachedCriteria countCriteria;
| private DetachedCriteria queryCriteria;
| @In
| private Session session;
|
| @SuppressWarnings (unchecked)
| public ListT getDatasetPage(int start, int pageSize) {
| log.trace(Fetching #0 records starting from #1, pageSize,
start);
| return
queryCriteria.getExecutableCriteria(session).setFirstResult(start).setMaxResults(pageSize).list();
| }
| @SuppressWarnings (unchecked)
| public int getDatasetSize() {
| log.trace(Fetching dataset size);
| return (Integer)
countCriteria.getExecutableCriteria(session).uniqueResult();
| }
| public void setCountCriteria(DetachedCriteria countCriteria) {
| this.countCriteria =
countCriteria.setProjection(Projections.rowCount());
| }
| public void setQueryCriteria(DetachedCriteria queryCriteria) {
| this.queryCriteria = queryCriteria;
| }
| }
|
Now any bean would use the paged lists in the following way:
@In (create = true)
| private CriteriaFetcherT fetcher;
| @DataModel
| private LazyListT records;
|
| protected DetachedCriteria buildCriteria() {
| return DetachedCriteria.forClass(T.class);

| @Factory (records)
| public void createRecords() {
| fetcher.setCountCriteria(buildCriteria());
| fetcher.setQueryCriteria(buildCriteria());
| records = new LazyListT(fetcher, 10);
| }
|
If sorting/filtering is needed, simply recreate the records variable with a
different fetcher that has the necessary sorts/filters built in. Until then,
the constructed LazyList stays in its scope (CONVERSATION is recommended),
fetching data pages as necessary.
Comments/suggestions are welcome - though the code is working already, so I'm
not looking for others to fix it for me :)

Thanks Gavin, that was quick :) Now, when is the next release planned? Do you guys do it once a month? Too bad I've missed yesterday's release with my bug report :( View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=4032487#4032487 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=4032487 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
[jboss-user] [JBoss Seam] - Re: Tomcat deployment with external datasource - is it possi
Actually, any JTA-compliant TM should do, I suppose, JOTM was picked only because it was the first one I've heard about (I plan to try Atomikos, and to ask around who's using what on Spring forum). No MC for me for sure, as any appservers are off-limits in our environment, and the ability to use Tomcat DS is a must. Now, sorry for being persistent, but could you expand a little bit more on why you couldn't use Seam-managed Tx in your setup?

[jboss-user] [JBoss Seam] - Re: Tomcat deployment with external datasource - is it possi
Baz, could you please post your setup that you said was working? And what do you mean by losing Seam-managed transactions? Did you still use Seam's transactional JSF interceptor? Overall, I'm leaning towards opening a JIRA issue for that, as it doesn't look like it's possible to mix the lookups to the Microcontainer JNDI and to the Tomcat one...

[jboss-user] [JBoss Seam] - Tomcat deployment with external datasource - is it possible?
I'm currently trying to adopt the Seam JPA example to our Tomcat deployment guidelines, and I'm facing a problem here... The example uses a DataSource that is supplied by the Microcontainer, in jboss-beans.xml: bean name=bookingDatasourceFactory | class=org.jboss.seam.microcontainer.DataSourceFactory | property name=driverClassorg.hsqldb.jdbcDriver/property | property name=connectionUrljdbc:hsqldb:./property | property name=userNamesa/property | property name=jndiNamejava:/DefaultDS/property | property name=minSize0/property | property name=maxSize10/property | property name=blockingTimeout1000/property | property name=idleTimeout10/property | property name=transactionManager | inject bean=TransactionManager / | /property | /bean | bean name=bookingDatasource class=java.lang.Object | constructor factoryMethod=getDataSource | factory bean=bookingDatasourceFactory / | /constructor | /bean | My question is: is it possible to somehow use the DataSource that is configured in Tomcat, as in ?xml version=1.0 encoding=UTF-8? | Context | Resource name=jdbc/DataSource auth=Container | type=javax.sql.DataSource maxActive=100 maxIdle=30 maxWait=1 username=username password=password driverClassName=oracle.jdbc.driver.OracleDriver url=jdbc url / | /Context | The idea is to be able to create data sources outside the deployed WAR, so that the same WAR could be deployed to different environments without any changes - this is a common requirement for production-level Tomcat applications. When I try to remove the data source definition from jboss-beans.xml, it gives me the name not bound exception (naturally), and I suspect that it only uses the Microcontainer's JNDI, ignoring the Tomcat-supplied one. Is such setup supported at all? Is there any way to configure the data source outside the WAR, while using Seam/Microcontainer/JPA stack?
