[EJB 3.0] New message: "How to initialize the State of an EJB3 Stateful Bean"

by Jerry Simone

User development, A new message was posted in the thread "How to initialize the State of an EJB3 Stateful Bean": http://community.jboss.org/message/522999#522999 Author : Jerry Simone Profile : http://community.jboss.org/people/jlsimone Message: -------------------------------------------------------------- In EJB2, you can pass the state to a stateful EJB using the home interface and the arguments that are defined for the ejbCreate method of the bean. This seems like it should be a simple thing do to, and I feel a little dumb asking the question, but how do you pass the state into an EJB3 stateful bean? All of the documentation that I have read so far assumes that the EJB creates its own state when the (no-arg) constructor is called. But in my case, the business logic of the application has already created a state (in the form of an object tree) that it needs to pass into the stateful bean. I have created what I consider a hack, which is to expose an "initialize" method in the remote/local interface. The initialize method sends the state to the EJB in the arguments of the method arguments. What are the better options for doing this? -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/522999#522999

[Beginner's Corner] New message: "Re: How do I enable pass-by-reference for EJB3 in JBoss AS container?"

by Jerry Simone

User development, A new message was posted in the thread "How do I enable pass-by-reference for EJB3 in JBoss AS container?": http://community.jboss.org/message/522997#522997 Author : Jerry Simone Profile : http://community.jboss.org/people/jlsimone Message: -------------------------------------------------------------- I am using remote interfaces. Generally, the client looks up and gets a remote interface to, say, EJB1. When the client requests additional functionality from the server, it makes a call to EJB1 which looks up EJB2 and EJB1 passes the remote interface for EJB2 back to the client. The client can now invoke the methods of EJB2 using the remote interface provided by EJB1. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/522997#522997

[JBoss Web Services] New message: "Slow performance with JBossWS 3.2.0_GA"

by Michael Eibeck

User development, A new message was posted in the thread "Slow performance with JBossWS 3.2.0_GA": http://community.jboss.org/message/522994#522994 Author : Michael Eibeck Profile : http://community.jboss.org/people/skymic Message: -------------------------------------------------------------- Hi, I use a JBoss AS V5.1.0_GA. I have downloaded JBossWS V3.2.0_GA separately and deployed it to JBossAS V5.1.0_GA. I use JDK V1.6.0_17. I generated a WS from a wsdl with wsconsume using the top down approach. I deployed the server part as a web application (war) on JBoss AS. The client part is included in a java client. During testing between client and server I noticed slow response time. I tracked down the problem and noticed, that the slow performance is due to slow response time of the WS stack. The request time from client to server is OK. The response time of the server response from server to client is up to 21 sec. That's literally the elapsed time from WS server response to WS client reception of this response. I have observed this slow response on all my WS messages, simple ones and complicated ones. To illustrate the problem I include one message here: wsdl: <message name="loginRequest"> <part name="loginRequestPart" element="sdo:login"/> </message> <message name="loginResponse"> <part name="loginResponsePart" element="sdo:loginResponse"/> </message> <operation name="login"> <input message="tns:loginRequest"/> <output message="tns:loginResponse"/> <fault name="LoginFault" message="tns:loginFault"/> </operation> <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/> <operation name="login"> <soap:operation/> <input> <soap:body parts="loginRequestPart" use="literal"/> </input> <output> <soap:body parts="loginResponsePart" use="literal"/> </output> <fault name="LoginFault"> <soap:fault name="LoginFault" use="literal"/> </fault> </operation> the involved types of the imported schema file are: <xs:complexType name="login"> <xs:sequence> <xs:element name="username" type="xs:string"/> <xs:element name="password" type="xs:string"/> <xs:element ref="sdo:scopeIdentifier"/> </xs:sequence> </xs:complexType> <xs:complexType name="loginResponse"> <xs:sequence> <xs:element name="securityToken" type="xs:hexBinary"/> <xs:element name="isSupervisor" type="xs:boolean"/> <xs:element name="isEditor" type="xs:boolean"/> </xs:sequence> </xs:complexType> Does anyone know what the reason for the slow response time of such a simple WS message could be? Thanks -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/522994#522994

I created two classes Order and OrderItems. The dialog just says: "Java Class must be configured" and there is nothing on the box below. Am I missing something from the configuration.

User development, A new message was posted in the thread "jBPM 4.3 - Multiple values (types) in JBPM4_VARIABLE for single entry.": http://community.jboss.org/message/522977#522977 Author : Martin Porter Profile : http://community.jboss.org/people/jedizippy Message: -------------------------------------------------------------- Hi, Unfortunately its not that easy to reproduce. It seems to occur randomly and we have so far not been able to identify the cause. We send in 5 parameters into each subprocess and it seems that one of these parameters (String) ends up in the same row as a value that is created inside a DecisionHandler java class. I will try and see if we can figure out what might be causing it. We are having major issues with ID generation at the moment and have implemented our own ID Generator to see if we can cure the problem. Maybe that will also solve this issue.I will update this thread if I find anything out.
