Re: Does clustering broadcast client's requests?
Thanks again Paul! 2008/11/1 Paul Fremantle [EMAIL PROTECTED] Only one node receives the request. Clustering shares the context across nodes. You can use mod_proxy to distribute the request to a server, or Synapse has some intelligent load-balancing code to do it.

Re: Clustering and passive replication
Thanks Afkham! 2008/10/21 Afkham Azeez [EMAIL PROTECTED] Hi Igor, At the moment, a member can only be started in the ACTIVE state. I started work last week on making it possible to configure a member to be ACTIVE or PASSIVE in the cluster configuration section. Part of this work is already available in the trunk. When an active member fails, the coordinator will activate one of the passive members. Also, the passive member will not start any transport listeners, hence will not be able to do anything useful until it is activated. Hopefully, this feature will be available in the next Axis2 release. Also like Paul said, you can use a Linux HA setup to achieve the same.

Re: In-flow request insertion
I am not clear about your requirement. But may be looking at Axis2 clustering would be usefull to you. Amila, Basically I want to do this: I have several services distributed on several servers. Only one of them will process client's requests- the primary one. If the primary fails, then one of the sleeping replicas will be elected as the new primary and will respond to the client's invocations from this moment on. My problem is: If the primary fails processing a specific client's invocation the new elected primary must be aware of the client's address in order to process and answer this request. On the next requests the client will invoke the new functional primary, so there's no problem. On clustering used by Axis, all requests are spread to all replicas, ins't it? In passive replication, only primary receives client's requests while the replicas sleep. If the primary fails, a replica will be elected new primary Thanks!

Guys with Axis2 clusering is it possible to build passive or active replication schemas? Or both? ;-) Best Regards, Igor Nogueira Santos

LocalTransportSender nullexceptionerror
Guys, I'm developing an handle. It is located at the postdispatch phase.
Actually, I copy the Messagecontext on a local static variable
everytime the handler's init method is called. On this handle, I may need
to to invoke another webservice operation. But, as I need to keep the
MessageContext's To parameter in order to send the new invocation respone
to the same client, I'm trying to use the Axis API.
Here's the code I'm trying:
Creating the Envelope to be sent:
public SOAPEnvelope creatSOAPEnvelop() {
SOAPFactory fac = OMAbstractFactory.getSOAP11Factory();
SOAPEnvelope envelope = fac.getDefaultEnvelope();
OMNamespace omNs = fac.createOMNamespace(
http://ws.apache.org/axis2;, ns1);
OMElement method = fac.createOMElement(urn:createSession, omNs);
OMElement value = fac.createOMElement(urn:createSession, omNs);
value.setText(Hello);
method.addChild(value);
envelope.getBody().addChild(method);
return envelope;
}
Here I try to use the LocalTransportSender:
LocalTransportSender sender = new LocalTransportSender();
ByteArrayOutputStream envelope = new ByteArrayOutputStream();
creatSOAPEnvelop().serialize(envelope);
sender.finalizeSendWithToAddress(contextomensagem, envelope);
contextomensagem is the variable I keep the MessageContext, it keeps the
To parameter. When I try this I receive java.lang.NullPointerException. Is
there something missing? Shouldn't the SOAPMessageBodyBasedDispatcher find
the action on the Envelope's body first element? Is there something else I
can do in order to fix it?
Thanks in advance,

In-flow request insertion
Guys, I have the following situation: I have a handler inserted on in-flow. It's phase is located after postdispatch phase. On this handler I modify the message, I mean the SOAPEnvelope and I'd like to re-send it to the beginning of the in-flow, like a new invocation to the service. Is it possible to do? If yes, what should I use? Thanks in advance, Igor Nogueira
Re: In-flow request insertion
Hey Martin, Thanks for answering! But I didn't understand. I mean the first phase of in-flow is TransportIn so shouldn't I send the message to this point, at the beginnig of the flow? How could I define an action there? Sorry me, but as a newbie at Axis and Java I'm confused ;-) Thanks again! Igor

TCP error
Guys, I'm trying to use the TCP protocol on axis. I've already uncommented
the tag on axis2.xml:
transportReceiver name=tcp
class=org.apache.axis2.transport.tcp.TCPServer
parameter name=port6060/parameter
If I set the client to invoke tcp://
127.0.0.1:8080/axis2/services/ShoppingCart it gives me
com.ctc.wstx.exc.WstxEOFException: Unexpected EOF in prolog I think
because of HTTP protocol.
If i set it to tcp://127.0.0.1:6060/axis2/services/ShoppingCart it gives
me:
java.net.ConnectException: Connection refused: connect at
org.apache.axis2.transport.tcp.TCPTransportSender.openTheConnection(TCPTransportSender.java:122)
error.
Here's my client:
EndpointReference targetEPR = new EndpointReference(
tcp://127.0.0.1:6060/axis2/services/ShoppingCart);
Options opts = new Options();
opts.setTo(targetEPR );
opts.setTransportInProtocol(Constants.TRANSPORT_TCP);
opts.setAction(urn:createSession);
//engaging addressing
ConfigurationContext ctx =
ConfigurationContextFactory.createConfigurationContextFromFileSystem
(D:\\axis2-1.4.1\\repository, null);
ServiceClient client = new ServiceClient(ctx,null);
client.setOptions(opts);
OMElement testando = client.sendReceive(getPayload());
private static OMElement getPayload() {
OMFactory fac = OMAbstractFactory.getOMFactory();
OMNamespace omNs = fac.createOMNamespace(
tcp://127.0.0.1:6060/axis2/services/ShoppingCart, );
OMElement method = fac.createOMElement(createSession, omNs);
OMElement value = fac.createOMElement(Text, omNs);
value.addChild(fac.createOMText(value, Axis2 Echo String ));
method.addChild(value);
return method;
}
Am I doing something wrong?
And another question, is there a way of using TCP protocol without engaging
addressing? I'm trying to invoke a web service from Jgroups. As it works
over TCP, I'll try to build the SOAP Envelope and send it from another group
member to test if I can invoke the service. This member may not be another
Web service, so I don't know if I'm able to use addressing on it...
Best Regards,
Igor Nogueira
Re: Jgroups
I've post this doubt to Jgroups list and they told that it is possible.
That's the idea:
byte[] buf=marshal(envelope); // marshal() needs to generate a byte[] buffer
from the envelope
Message msg=new Message(null, null, buf);
disp.cast(null, msg, ...);
On the receiver side:
Object handle(Message req) {
byte[] buf=msg.getBuffer();
envelope=unmarshal(buf);
I know I can build a SOAPEnvelope with Axis and I'm marshaling the SOAP into
a byte[] this way:
ByteArrayOutputStream baos = new ByteArrayOutputStream();
SOAPEnvelope envelope =
envelope.serialize(baos);
My doubt is that the receiver side would be Axis2. In this case if I
engage a module to unmarshal the message, would it work even if the message
received ins't a SOAPEnvelope? Because that's the situation.
Best Regards,
Igor Nogueira

Re: ServiceContext in OperationContext does not match error

That´s a clent side envelope: ?xml version='1.0' encoding='utf-8'?soapenv:Envelope xmlns:soapenv= http://schemas.xmlsoap.org/soap/envelope/;soapenv:Header xmlns:wsa= http://www.w3.org/2005/08/addressing;wsa:To http://127.0.0.1:8080/axis2/services/ShoppingCart/wsa:Towsa:MessageIDurn:uuid:79E6715443849740D21222111363367/wsa:MessageIDwsa:Actionurn:addItem/wsa:Action/soapenv:Headersoapenv:Bodyns1:addItem xmlns:ns1=http://ws.apache.org/axis2 Testando!!!/ns1:addItem/soapenv:Body/soapenv:Envelope That´s a server side one: ?xml version='1.0' encoding='utf-8'?soapenv:Envelope xmlns:soapenv= http://schemas.xmlsoap.org/soap/envelope/;soapenv:Bodysoapenv:Faultfaultcodesoapenv:Server/faultcodefaultstringunknown/faultstringdetail //soapenv:Fault/soapenv:Body/soapenv:Envelope Thanks, and sorry me for the insistence :-)
Re: SOAPSession error
Hi Charitha! Thanks again! I found out the error. The first invocation I was doing to the service was a fireAndForget so, as the service didn´t reply to this invocation, the servicegroupid wasn't being sent. I changed the service implementation, now everything is ok. Best regards, Igor Nogueira Santos
SOAPSession error
Hello guys, I'm trying to use soapsession scope to test a service. I've already engaged the addressing module, but I just can't access the service's operations. I've got the following message on log: [WARN] triggerActionNotSupportedFault: messageContext: [MessageContext: logID=urn:uuid:99B68224CFE1AABF211222024829486] problemAction: urn:anonOutonlyOpResponse [ERROR] The [action] cannot be processed at the receiver. org.apache.axis2.AxisFault: The [action] cannot be processed at the receiver. at org.apache.axis2.addressing.AddressingFaultsHelper.triggerAddressingFault(AddressingFaultsHelper.java:373) at org.apache.axis2.addressing.AddressingFaultsHelper.triggerActionNotSupportedFault(AddressingFaultsHelper.java:336) at org.apache.axis2.handlers.addressing.AddressingValidationHandler.checkAction(AddressingValidationHandler.java:149) at org.apache.axis2.handlers.addressing.AddressingValidationHandler.invoke(AddressingValidationHandler.java:55) at org.apache.axis2.engine.Phase.invoke(Phase.java:317) at org.apache.axis2.engine.AxisEngine.invoke(AxisEngine.java:264) at org.apache.axis2.engine.AxisEngine.receive(AxisEngine.java:163) at org.apache.axis2.transport.http.HTTPTransportUtils.processHTTPPostRequest(HTTPTransportUtils.java:275) at org.apache.axis2.transport.http.AxisServlet.doPost(AxisServlet.java:133) at javax.servlet.http.HttpServlet.service(HttpServlet.java:637) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:286) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:845) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Unknown Source) What's goino on?

Re: SOAPSession error
Hey all, Forget about my last doubt! I was setting the options object wrongly. But now I've got another error. As I said, I'm using soapsession as scope but I can´t live in the same session throughout different invocations. I'm trying to test the ShoppingCart example. I've deployed the service as soapsession, engaged the adressing mudule to the client and set the ManageSession flag true. Is there something missing? Here's an example of a soap envelope the client is composing: ?xml version='1.0' encoding='utf-8'?soapenv:Envelope xmlns:soapenv= http://schemas.xmlsoap.org/soap/envelope/;soapenv:Header xmlns:wsa= http://www.w3.org/2005/08/addressing;wsa:To http://127.0.0.1:8080/axis2/services/ShoppingCart /wsa:Towsa:ReplyTowsa:Addresshttp://www.w3.org/2005/08/addressing/none/wsa:Address/wsa:ReplyTowsa:MessageIDurn:uuid:57AA5B8A82899D9AAD1222038876428/wsa:MessageIDwsa:Actionurn:createSession/wsa:Action/soapenv:Headersoapenv:Bodyns1:createSession xmlns:ns1=http://ws.apache.org/axis2; //soapenv:Body/soapenv:Envelope There isn´t a servicegroupid tag.

Re: SOAPSession error

Re: SOAPSession error
Sorry, I've sent the answer form my classmate's mail...We are trying to implement a passive replication schema in stateful webservices. We´re trying to use the soapsession in order to serialize it and recover it on another server to keep replica's state up-to-date. Thanks! 2008/9/21 Tina Silva [EMAIL PROTECTED] Hi Charitha, First of all thanks for answering! I did what you said: ConfigurationContext ctx = ConfigurationContextFactory.createConfigurationContextFromFileSystem (D:\\axis2-1.4.1\\repository, null); ServiceClient client = new ServiceClient(ctx,null); client.engageModule(addressing); Options opts = new Options(); opts.setManageSession(true);... It really doesn't report that client is Unable to engage module:addressing . But I still can't access the session content in a different invocation. That's my situation: I have a .jsp with 3 methods. testCreate - Creates a List element on the ServiceContext callse ShoppingCart; testAdd - Adds an element in ShoppingCart; testList - List ShoppingCart's content; I call the methods exactly on this order. testCreat works well, but I get a nullexception when I call testAdd and testList, because I just can´t recover ShoppingCart in a different invoke. My Soap Envelopes are just like this: ?xml version='1.0' encoding='utf-8'?soapenv:Envelope xmlns:soapenv= http://schemas.xmlsoap.org/soap/envelope/;soapenv:Header xmlns:wsa= http://www.w3.org/2005/08/addressing;wsa:To http://127.0.0.1:8080/axis2/services/ShoppingCart /wsa:Towsa:ReplyTowsa:Address http://www.w3.org/2005/08/addressing/none/wsa:Address/wsa:ReplyTowsa:MessageIDurn:uuid:F3FEEC679D471BCF2E122204804/wsa:MessageIDwsa:Actionurn:createSession/wsa:Action/soapenv:Headersoapenv:Bodyns1:createSession xmlns:ns1=http://ws.apache.org/axis2; //soapenv:Body/soapenv:Envelope There's no groupid tag, is it right?

Client should report Unable to engage module:addressing error if addressing module is not found. In order to engage addressing at client side, create a configurationContext and use it when instantiating ServiceClient or stub as follows. ConfigurationContext ctx = ConfigurationContextFactory.createConfigurationContextFromFileSystem(\home\user\axis2-client\repository, null); SoapSessionServiceStub stub = new SoapSessionServiceStub(ctx); addressing-1.4.1.mar can be placed at the modules directory of \home\user\axis2-client\repository.

Re: Rebuilding Context
Same doubt... 2008/9/20 Tina Silva [EMAIL PROTECTED] Hello Everybody! I'm new at this list. I am new at Java and Axis too, so I really need your help. I'd like to save and restore the message context. Actually, I've alredy serialized it and sent it to another service as an OMElement object. What do I have to do to rebuild it? As far as I know, the messagecontext class implements the readExternal method, I just don't know what to do to unserialize it... Thanks in advance!
MessageContext writeExternal
Hey all! I've got a doubt. How can I save the MessageContext? I have following piece of code: ByteArrayOutputStream baos = new ByteArrayOutputStream(); ObjectOutputStream oos = new ObjectOutputStream(baos); oos.writeObject(MessageContext.getCurrentMessageContext()); But it doesn't work. It gives me the following error: Caused by: java.lang.ClassCastException: java.lang.Object cannot be cast to java.io.ObjectOutput at ShoppingCart.getState(ShoppingCart.java:97) ... Is that the right way of saving the Message context? What's wrong on this code? Thank you in advance, Igor Nogueira
Re: passive replication
Thanks! I'll read it! 2008/9/16 Deepal jayasinghe [EMAIL PROTECTED] Yes , we have implemented a way to keep session aware data. However you have to remember that all the data have store in Axis2 Context hierarchy. If you look at Axis2 clustering then you can understand the rest. -Deepal http://blogs.deepal.org Igor Nogueira wrote: Hello guys, I'm new at axis2 and I have a doubt; I need to implement a passive replication mechanism for stateful WebServices.

Re: passive replication
I've read it and tried to work with the ConfigurationContext just to test it, but it isnt's serializable, is it? If I need to keep the backup replicas up-to-date, so I shouldn´t use soapsession as session scope, but application or group scope isn't it? Thanks you in advance! P.S: My English is awful, I hope you understand me ;-)
