[Wsag4j-users] Error on SampleAgreementTemplate

[SunDevil L. <sun...@gm...>]

I am new for the WSAG4J rest 2.0. I just follow the steps to execute the
software and the source is attached. I got a error and I need help to deal
with it.

The statement

SampleAgreementTemplate negotiationTemplate = new
SampleAgreementTemplate(template);

causes errors

Exception in thread "main" java.lang.NoClassDefFoundError:

Hi Giacomo,

>> org.apache.xmlbeans.impl.values.XmlAnyTypeImpl cannot be cast to org.ogf.graap.wsag4j.types.configuration.WSAG4JEngineConfigurationDocument

this error can basically have two reasons:

1) the wsag4j engine types are not included in the classpath and
therefore the engine configuration is not correctly instantiated by
xmlbeans.
2) the wsag4j engine configuration file is corrupt, i.e. the xml root
element has a wrong namespace or name.

You should first check if you have included the wsag4j-common-types
jar file in the classpath of your project. In case you have, check if
the engine configuration file is correct (i.e. compare to default
configuration file).


Best regards
Oliver

Re: [Wsag4j-users] wsag4j as a standalone application

[Oliver W. <ow...@us...>]

Hi Giacomo,

the wsag4j modules are available as maven modules via the Maven
Central repository.
If you want to implement an OSGI application you can use the
wsag4j-engine module
(jar files) for that.

Best regards,
Oliver

[Wsag4j-users] wsag4j as a standalone application

[Giacomo T. <g.t...@ie...>]

Hi,
I am new to this software and i need some clarification regarding how to
use it and also how to customize it. First of all I tried the software as
it is, I deployed the war server in a tomcat7 container and everything
seems to work correctly (with the WSRF distribution). However I read on the
site " It is also possible to use the WSAG4J engine without a remote stack
at all, e.g. in a desktop application", this is exactly what I need. In
detail, I want to integrate WSAG4J in an OSGi container, so all remote
calls must become local calls between OSGi bundles. I tried to inspect the
code but there are many jars and I can't understand which ones are needed
for my purpose. Can someone give me some suggestions or explain where I can
find a tutorial explaining which jars or classes are needed to build a
WSAG4J server without remote stack?

Thanks in advance
Giacomo

Re: [Wsag4j-users] Validation of the negotiation offer against template failed.

[Oliver W. <ow...@us...>]

Hi Adriano,

what I see from the client log is that the negotiation constraint
"TimeConstraintSDT_TimeConstraint_START_TIME" is defined wrong. You
set a min/max inclusive value which is applicable for a date time
element, but you refer in the constraint location element to the
complex type ".../wsag4jt:TimeConstraint" (not to the start or end
time). Therefore the validation must fail. You should use a valid
XPath expression in your negotiation constrains location, such as:

declare namespace
wsag-tc='http://schemas.wsag4j.org/2009/07/wsag4j-scheduling-extensions';declare
namespace wsag='http://schemas.ggf.org/graap/2007/03/ws-agreement';$this/wsag:Terms/wsag:All/wsag:ServiceDescriptionTerm[@wsag:Name
= 'TIME_CONSTRAINT_SDT']/wsag-tc:TimeConstraint/wsag-tc:StartTime

Moreover, make sure that you use the namespace prefixes that you
defined in the beginning of your XPath expression throughout the
expression (i.e. don't use wsag4jt in the expression if you defined
the prefix wsag4-tc in the XPath declaration section).

You should find more detailed information on the validation process in
the server error log (i.e. catalina.log when you use tomcat). This
should make debugging for such issues more easy. If there are more
problems with constraint validation please also attach the server log.

Best regards,
Oliver

Hi Adriano,

could you please provide the complete error or the server log? Usually
you should find a more specific error message here, for example which
part of the negotiation constraint checking failed.

Basically, all negotiation offers are checked against the creation
constraints of the template and additionally against the negotiation
constraints of the previously exchanged
offers. The detailed XML validation error can be found in the error
details or the log file.

This error may also occur in case the negotiation offer is not valid
according to the schema, for example a required element/attribute is
missing; or, in case you use extension points, the corresponding
schema is missing on the server.

Best regards,
Oliver

Re: [Wsag4j-users] Validation of the negotiation offer against template failed.

[Oliver W. <ow...@us...>]

Hi Adriano,

could you please provide the complete error or the server log? Usually
you should find a more specific error message here, for example which
part of the negotiation constraint checking failed.

Basically, all negotiation offers are checked against the creation
constraints of the template and additionally against the negotiation
constraints of the previously exchanged
offers. The detailed XML validation error can be found in the error
details or the log file.

This error may also occur in case the negotiation offer is not valid
according to the schema, for example a required element/attribute is
missing; or, in case you use extension points, the corresponding
schema is missing on the server.

Best regards,
Oliver

[Wsag4j-users] Validation of the negotiation offer against template failed.

[Adriano G. <A.G...@le...>]

Hi,

I upgraded wsag4j to 2.0.0
everything is working fine with the provided template sample-template.xml
but if I want to used my template carmen-template.xml (see below) I get:

<ErrorCode dialect="http://schemas.scai.fraunhofer.de/wsag4j">2101</ErrorCode>
            <Description xml:lang="en">org.ogf.graap.wsag.api.exceptions.NegotiationException: Validation of the negotiation offer against template failed.</Description>
            <Description xml:lang="en">	at org.ogf.graap.wsag.server.engine.GenericNegotiation.negotiate(GenericNegotiation.java:336)</Description>
.......

Any idea why?

Re: [Wsag4j-users] ERROR: Invalid number of advance reservation time constraints in template.

[Oliver W. <ow...@us...>]

Hi Adriano,

with the 2.0.0 version we fixed some typos in the example templates
and the corresponding code in the pattern module. You should change
the name of your resource service description term from "RESOURCE_STD"
to "RESOURCE_SDT". Simmilar name changes are required for
"COMPUTE_SDT".

Best regards,
Oliver

[Wsag4j-users] ERROR: Invalid number of advance reservation time constraints in template.

[Adriano G. <A.G...@le...>]

Hi everybody,

I get this error message and I have no idea how to fix it:
java.lang.IllegalStateException: Invalid number of advance reservation time constraints in template.
	at org.ogf.graap.wsag.api.pattern.AdvanceReservationPattern.initialize(AdvanceReservationPattern.java:114)
	at org.ogf.graap.wsag.api.pattern.AdvanceReservationPattern.<init>(AdvanceReservationPattern.java:102)
	at org.ogf.graap.wsag.samples.actions.SampleAgreementTemplate.<init>(SampleAgreementTemplate.java:319)
	at uk.leeds.csp.client.Main.main(Main.java:226)

I created my Template 

<wsag:Template wsag:TemplateId="1" xmlns:wsag="http://schemas.ggf.org/graap/2007/03/ws-agreement">

    </wsag:All>
  </wsag:Terms>
  <wsag:CreationConstraints>
  <!-- Resources_SDT -->

  </wsag:CreationConstraints>
</wsag:Template>

I added the line below in wsag4j-engine.config

<wsag4j-config:Validator>
                <wsag4j-config:SchemaImports>
                    ......
                    <wsag4j-config:SchemaFilename>/validator/CMAC-scheduling-types.xsd</wsag4j-config:SchemaFilename>
                </wsag4j-config:SchemaImports>
</wsag4j-config:Validator>

then I created my CMAC-scheduling-types.xsd which is similar to wsag4j-scheduling-types.xsd with the Frequency element:

Hi everybody,

I am trying to set up wsag4j-client using eclipse and as a maven project.
Once inserted the following lines in pom.xml

<dependencies>
    <dependency>
      <groupId>net.sf.wsag4j.wsrf</groupId>
      <artifactId>wsag4j-wsrf-client</artifactId>

    </dependency>
  </dependencies>

        <repositories>

                        <url>http://packcs-e0.scai.fraunhofer.de/archiva/repository/maven</url>
                </repository>
        </repositories>

I get "Missing artefact net.sf.wsag4j.wsrf ..."
But if I change <url>http://packcs-e0.scai.fraunhofer.de/archiva/repository/maven</url> 
With <url>http://packcs-e0.scai.fraunhofer.de/archiva/repository/internal</url>
Which is the old repository, this is fine.

Anybody knows way?
Shall I keep /maven or /internal ?

Cheers,

Re: [Wsag4j-users] Client's Endpoint Reference from wsag4j server

[Oliver W. <ow...@us...>]

Hi Adriano,

the process is slightly different. The idea is when a new negotiation
instance is created, the first thing that has to be done is to
identify the responsibilities of the negotiating parties. Therefore we
pass in the negotiation context. That context provides the metadata
for the new negotiation instance and clarifies the roles and
responsibilities. Let's take a look on the following code in order to
illustrate the idea:

NegotiationContextDocument negContextDoc =
NegotiationContextDocument.Factory.newInstance();
NegotiationContextType negContext = negContextDoc.addNewNegotiationContext();
negContext.setAgreementFactoryEPR(factory.getEndpoint());
negContext.setAgreementResponder(NegotiationRoleType.NEGOTIATION_RESPONDER);

This code creates a new negotiation context and sets an agreement
factory endpoint. This endpoint identifies the agreement factory for
which an agreement offer is negotiated. If a suitable offer was
negotiated this factory is the place to create the agreement with,
because this factory should be aware of the preceding negotiation
process. The property agreement responder specifies that the responder
of an agreement creation request (that is the agreement factory) is
the same party as the negotiation responder. In other words, the party
that initiates the negotiation process must also send the create
agreement request. That's all what is specified in the context, no EPR
yet.

Basically, this is a very specific signaling scenario. There might be
other scenarios where the roles are changed. Imagine a situation where
a system automatically starts service advertisements or negotiation
processes with customers, but the customers are finally in charge to
create the agreements if they find some offers beneficial. WSAG4J does
not support such scenarios out of the box, it only provides a
framework that allows you to implement such scenarios.

Let's come back to your question. The first thing is that when you
want to pass an EPR of the client to a server you first need a client
resource that is represented by that EPR. The EPR could for example
represent a WSRF resource, it could be also some other kind of
remotely accessible resource. Let's assume you have deployed a servlet
that represents the initiator at http://foo.org/bar. This servlet
should be invoked when the server creates the agreement. This can be
achieved through the following code:

...
// create an offer based on template1 and set the URL to you servlet
AgreementOfferType offer = new AgreementOfferType(template1);
offer.setInitiatorEPR(EndpointReferenceType.Factory.newInstance());
offer.getInitiatorEPR().addNewAddress().setStringValue("http://foo.org/bar");
AgreementClient agreement = factory.createAgreement( offer );
...

In your create agreement action that is invoked for that offer (the
action that registered for offers based on template1) you need to
extract the initiator EPR as follows:

public Agreement createAgreement( AgreementOffer offer )
{
    EndpointReferenceType epr = offer.getInitiatorEPR();
    // now get the address of the EPR, create a java.net.URL and call
the initiator
    // servlet through a HTTP GET request
    ...
}

As mentioned before, I have tested this with the 2.0.0 version. I'm
not sure if this also works for 1.0.2. I hope this helps.

Best regards,
Oliver

Re: [Wsag4j-users] Client's Endpoint Reference from wsag4j server

[Oliver W. <ow...@us...>]

Dear Adriano,

I checked your test program against the wsag4j 2.0.0 version from
sourceforge and for me it seems to work.
I changed the template and factory id back to the sample ids and the
test worked fine.

I guess your problem is that the initiator agreement id is not
automatically set by the API when creating an
agreement offer from a negotiated offer. As I explained before, the
initiator id is primarily foreseen by the specification
for symmetric signaling scenarios. If you want to use the initiator
EPR in a custom scenario in a slightly different way,
this is still possible. In that case you need to set the EPR in your
code. The following snippet illustrates this:

            AgreementOfferType offer = new AgreementOfferType(
selectedCounterOffer );
            offer.setInitiatorEPR(
EndpointReferenceType.Factory.newInstance() );
            offer.getInitiatorEPR().addNewAddress().setStringValue(
"http://foo.org" );
            System.out.println( " EPR in client \n" + offer.getInitiatorEPR() );

            AgreementClient agreement =
getFactoryClient().createAgreement( offer );

On the server side you can than query the agreement initiator with the
normal API, i.e.:

            offer.getInitiatorEPR();


Best regards,
Oliver

Re: [Wsag4j-users] Client's Endpoint Reference from wsag4j server

[Adriano G. <A.G...@le...>]

Dear Oliver,

I am using WSRF.
I attach a simple client which contacts the wsag4j server.
I am using wsag4j-engine.config from the wsag4j-server-1.0.2
Thank you very much.

Kind regards,
Adriano

Subject: Re: [Wsag4j-users] Client's Endpoint Reference from wsag4j server

Dear Adriano,

The EPR you try to use is basically the initiator agreement EPR. It
should be used when you have a scenario were each party needs a copy
from the created agreement after agreement creation, i.e. for
bi-lateral monitoring (see WS-Agreement spec, section Port Types and
Operations - signaling scenarios). However, this should basically
work. I took a look on the WSRF implementation and the initiator EPR
is set in the WSRF stack. By the way, negotiation is supported by the
framework out of the box.

In order to help you could you please tell me which implementation you
use, WSRF or REST? Is the Initiator EPR set on the client side (this
is not done automatically). Could you please provide a simple test
project?

Best regards,
Oliver

[Wsag4j-users] Client's Endpoint Reference from wsag4j server

[Adriano G. <A.G...@le...>]

Hi,

I am using wsag4j 1.0.2 and working on a renegotiation protocol.
I am struggling to retrieve the client Endpoint Reference fron the server side (I need this information because the server might recontact the client in the future to renegotiate the agreement).
I tried with offer.getInitiatorEPR() in SampleCreateAgreementAction
but I get a null pointer.

Does anybody know how to retrieve the client Endpoint Reference/url.

Thank you very much in advance,

Kind regards,
Adriano

Re: [Wsag4j-users] problems in checkout from SVN

[Oliver W. <ow...@us...>]

The web page http://wsag4j.sourceforge.net/site/source-repository.html
lists the relevant ways to access the project sources in the SVN
repository. If you use a SVN client to checkout the sources you have
to use the repository URL listed in section Anonymous Access. The
repository URL in section Web Access is intended only to be used from
your web browser. Accessing this URL from a SVN client will result in
the redirect cycle error.

To make it short, use the following URL in your SVN client in order to
check out a released version:

https://wsag4j.svn.sourceforge.net/svnroot/wsag4j/framework/tags

or use the following URL to check out the trunk version:

https://wsag4j.svn.sourceforge.net/svnroot/wsag4j/framework/trunk
