Hello, I got a doubt about the support to Drools 5 announced on Seam 2.2.0 release notes (and posts on blogs all over the internet, like the In Relation To...). It says: "We've also moved our Drools <http://www.jboss.org/drools/> support from Drools 4 to Drools 5" Maybe I'm misunderstanding exactly what Seam team intended to say, but I got confused. In SVN, there's another branch, called Seam_2_2_Drools5, and there's a lot of commits trying to integrate Seam and the Drools 5 API. On the otherhand, the branch Seam_2_2 really doesn't seems to support this API (KnowledgeBase and other new stuff). It looks like I still have to use the old drools 4 api to make Seam 2.2.0 work with Drools. Am I wrong?

Implementing REQUIRES_NEW for seam transaction management

by Stuart Douglas

I would like to implement REQUIRES_NEW as a transaction type for the @Transactional annotation. My basic plan is: - Create a TransactionManager component that can be installed into components.xml, and give the option to configure the JNDI location of the JTA TransactionManager. - modify the Work.workInTransaction method to check if the existing transaction need to be suspended, as if so use the TransactionManager component to suspend and resume the transaction. I can't help thinking that there is some problem with this approach, otherwise someone else would have already done it. I also know that TransactionManager is not supposed to be used by the application, does anyone know if this will cause problems? I would also like to implement the ability to control seam global transactions based on a flag in pages.xml, so they can be disabled for specific views. Would anyone have any objections to this?

Maven Seam version within a Seam distribution

by Snjezana Peco

I have tried to find Maven versions of Seam and required libraries in order to fix https://jira.jboss.org/jira/browse/JBIDE-4813. I have succeeded to find versions of the required libraries in <SEAM_HOME>/build/root.pom.xml, but haven't succeeded to find the version of Seam (root.pom.xml contains @seam.version@). I have also tried to find the version of Seam within the jboss-seam.jar file. For EAP 5.0, the jboss-seam.jar file contains the 2.2.0.EAP version that isn't any Maven version. Is it possible to find the Maven version of Seam within any Seam distribution? Snjeza

seam-gen

by Info

Hi I am using Dan Allens book ( Seam in Action) and have been following the instructions to get seam-gen going. I have hit an error in 'seam generate' related to Hibernate and I am unsure of how to troubleshoot it. If anyone has any ideas I would appreciate it.

Importing the photoalbum maven application to m2eclipse/JBoss Tools

by Snjezana Peco

I have tried to import the photoalbum application from http://jboss.org/downloading/?projectId=jbossrichfaces&url=http://downloa... to Eclipse. There are a few issues related to m2eclipse and WTP. In order to import the application to Eclipse and configure it to work with m2eclipse and JBoss Tools, it is necessary to do the following: 1. ejb, ear, web modules - change the names of the modules to: photoalbum-ear photoalbum-ejb photoalbum-web 2. ear module - set the version to 5 in maven-ear-plugin - set photoalbum-ear final-name to photoalbum-ear and add bundleFileName to the web and ejb module of maven-ear-plugin - obliged because the WTP deployer ignores deployName - see https://jira.jboss.org/jira/browse/JBIDE-4655 i https://issues.sonatype.org/browse/MNGECLIPSE-1564 - create application.xml and jboss-app.xml in src/main/application/META-INF - see https://jira.jboss.org/jira/browse/JBIDE-4809 - change context-root from photoalbum to photoalbum-web in pom.xml and application.xml because m2eclipse ignores context-root - see https://issues.sonatype.org/browse/MNGECLIPSE-1564 3. ejb module - move component.properties from src/main/resources-filtered to src/main/resources with the following contents: # #Mon Sep 15 14:29:32 EEST 2008 jndiPattern=photoalbum-ear/#{ejbName}/local embeddedEjb=false and remove src/main/resources-filtered - remove the configuration of maven-resource-plugin I haven't succeeded to configure Maven resource filtering within m2eclipse. But, as it is, Maven resource filtering is unnecessary here because I have had to change the EAR's final name. 4) There is a bug in org.jboss.tools.jsf/PostInstallJsfFacetDelegate - this class calls IProject.refreshLocal within the facet install procedure which, sometimes, throws an exception. Until the bug is fixed, you can workaround it by calling Maven>Update Project Configuration on the EAR project In order to test importing the photoalbum application, you can do the following: - install/update m2eclipse >= 0.9.9.20090820 - install the latest JBoss Tools trunk - define Seam Runtime 2.1.1.GA and the DefaultDS connection profile (they can be set after checking out Maven projects) - call Import>Check out Maven Projects from SCM - select svn for SCM URL and enter http://anonsvn.jboss.org/repos/jbosstools/workspace/snjeza/photoalbum - finish the Import wizard You will get the photoalbum application containing the JBoss Tools settings.

Subtle changes in seam-gen affecting JBDS :)

by Max Rydahl Andersen

Hi, I've added Pete as a watcher on https://jira.jboss.org/jira/browse/JBDS-828 but if someone else knows about what components-war-tokenized.xml is and why components.xml is not targeting AS5 so JBoss Tools/JBDS breaks...then please feel free to comment. p.s. I assume the tokenized.xml is to add some flexibility and that is great, but adding that flexibility to JBDS this close to codefreeze is something I would like to avoid if possible. Next version we should sync on what flexibilities were added since I got a feeling that more than this were added to seam-gen recently ;) /max

PDF: missing pageEventClass

by Kenneth Christensen

Maybe someone could explain me why the "pageEventClass" have been removed from the UIDocument and why is it not supported by Seam PDF anymore? JBoss Seam 2.0.3: @Override public void encodeBegin(FacesContext context) throws IOException { super.encodeBegin(context); stream = new ByteArrayOutputStream(); try { writer = createWriterForStream(stream); initMetaData(context); initPageEvent(writer); processHeaders(); document.open(); } catch (DocumentException e) { throw new RuntimeException(e); } } protected void initPageEvent(DocWriter writer) { if (pageEventClass != null && writer instanceof PdfWriter) { try { PdfPageEvent event = (PdfPageEvent) Class.forName(pageEventClass).getConstructor().newInstance(); ((PdfWriter) writer).setPageEvent(event); } catch (Exception e) { throw new RuntimeException(e); } } } JBoss Seam 2.2.0: @Override public void encodeBegin(FacesContext context) throws IOException { super.encodeBegin(context); stream = new ByteArrayOutputStream(); try { writer = createWriterForStream(stream); initMetaData(context); processHeaders(); document.open(); } catch (DocumentException e) { throw new RuntimeException(e); } } Best regards Kenneth Christensen

Reaching the seam-dev mailing list is a nightmare (Second try)

by denis.forveille＠gmail.com

(Second try..) Hello, I don't know if moderators and the list manager(s) are aware of this, but this is a nightmare to post a message to the mailing list. Almost none of my message have reached the list on the first post, and some never reach it after the third 3 tentative. For those I gave up (!) I understand that this list has to be moderated and that moderators receives tons of spam and it's hard to filter messages, that people are busy doing more important things etc etc You can not image the amount of frustration this generates for a newly committer like me that need, from time to time, advises on how to act regarding the code before committing and potentially break things, or simply ask a questions that are obviously not of the domain of the general forum (Like fixing the build or the WiKi). I don't know if they are other means to ask dev-related questions, but as-is, the seam-dev list is not an answer, at least for "external" people like me as most of the message never reach the list. I hope this message will reach people that can act on this. If not ill re- post it 3 times, no more. Thanks for your time. Denis Forveille
