[JBoss Web Services] New message: "Re: org.jboss.ws.WSException: Invalid HTTP server response [411] - Length Required"

by Michael Eibeck

User development, A new message was posted in the thread "org.jboss.ws.WSException: Invalid HTTP server response [411] - Length Required": http://community.jboss.org/message/521363#521363 Author : Michael Eibeck Profile : http://community.jboss.org/people/skymic Message: -------------------------------------------------------------- Problem solved. The remote WSEndpoint did not like the HTTP Chunking feature activated. Now I has to disable this feature for my WS client. This can be done as follows: QName qname = new QName(namespace,"TapasAuthentificationServiceV1.0"); String className = System.getProperty("xxxx.service.factory.auth", xxxxAuthentificationServiceV10_Service.class.getName()); xxxxAuthentificationServiceV10_Service service = (xxxxAuthentificationServiceV10_Service)getServiceInstance(className, serviceUrl, qname); // switch off Chunking feature of HPPP1.1 ChunkedEncodingFeature feature = new ChunkedEncodingFeature(false); return service.getxxxxAuthentificationServiceV10SOAPhttp(feature); The JBoss version which I used is JBoss-5.1.0-GA. This version comes with the JBossWS 3.1.0 stack. The class ChunkedEncodingFeature exists only in JBossWS 3.2.0 stacks and higher. I has to download JBossWS 3.2.0 separately and install it for JBoss-5.1.0-GA which worked fine (follow the Installation guide for JBossWS). When I deployed and run my application the exception was gone. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/521363#521363

[JBoss Cache] New message: "How to evict a node when all its children have been evicted?"

by Nicolas Filotto

User development, A new message was posted in the thread "How to evict a node when all its children have been evicted?": http://community.jboss.org/message/521362#521362 Author : Nicolas Filotto Profile : http://community.jboss.org/people/nfilotto Message: -------------------------------------------------------------- Hi All, Since the last past days, I have been working on finding a memory leak in my program. I finally identified it, in fact it is due to the fact that in JBC when all the sub nodes of a JBC node are evicted, the parent node is never evicted even if it has not been declared resident. Let's take a concrete example We assume that I have the following configuration {code} <eviction wakeUpInterval="5000"> <default algorithmClass="org.jboss.cache.eviction.FIFOAlgorithm" eventQueueSize="1000000"> <property name="maxNodes" value="1" /> </default> </eviction> {code} if I first call cache.put(Fqn.fromElements("1","1"),key,value) If I then call cache.put(Fqn.fromElements("2"),key,value), the node "/1/1" is evicted but its parent node "/1" is not evicted If I then call cache.put(Fqn.fromElements("3"),key,value), the node "/2" is evicted but node "/1" is still present. This zombie node (i.e. node "/1") is the cause of my memory leak. So my question is, is there a way to make JBC evicts those kind of nodes? To limit the memory leak, I implemented a EvictionActionPolicy, but I would like to know if there is a better solution. If I don't have any other way, could you check my code below and tell me how I could improve it, because up to now, it fixes about 95% of the memory leak but it seems that it doesn't work 100% of the time: {code} public class MyEvictionActionPolicy implements EvictionActionPolicy { Cache<?, ?> cache; private static final Log log = LogFactory.getLog(DefaultEvictionActionPolicy.class); public void setCache(Cache<?, ?> cache) { this.cache = cache; } public boolean evict(Fqn fqn) { boolean result; try { if (log.isTraceEnabled()) log.trace("Evicting Fqn " + fqn); cache.evict(fqn); result = true; } catch (Exception e) { if (log.isDebugEnabled()) log.debug("Unable to evict " + fqn, e); result = false; } try { Fqn parentFqn = fqn.getParent(); // My problem only occurs with the nodes under if (parentFqn.size() == 2 && (parentFqn.get(0).equals(JBossCacheWorkspaceStorageCache.CHILD_NODES) || parentFqn.get(0).equals( JBossCacheWorkspaceStorageCache.CHILD_PROPS))) { Node<?, ?> node = cache.getNode(parentFqn); Set<Object> names = node.getChildrenNames(); if (names.isEmpty() || (names.size() == 1 && names.contains(parentFqn.get(1)))) { cache.evict(parentFqn); } } } catch (Exception e) { if (log.isDebugEnabled()) log.debug("Unable to evict " + fqn, e); } return result; } } {code -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/521362#521362

User development, A new message was posted in the thread "Unable to distingusih between  pooled-Actors and Swimlane": http://community.jboss.org/message/521344#521344 Author : Ronald van Kuijk Profile : http://community.jboss.org/people/kukeltje Message: -------------------------------------------------------------- Yes, it still is wrong... As I said, locking a token is a technical thing internally used by jBPM. Regarding your problem. If a task is assigned to pooled actors they all see it in the pooled task list in their ui. Once the FIRST one clicks on it, you should assign the task to that user. Not earlier. The others won't see it now unless you re-assign it to 'null'. Once the assigned user complets the task, it is gone anyway.... -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/521344#521344

I do not know who will do it first. if any one of the user (A,B,C,D) does approve others should not approve the Registration So that i use locking the token. If it is wrong way please suggent the way to do -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/521340#521340
