JMX and Webservice

Hi,
I am using JMX in my application which supports HTTP, RMI, CORBA, TL1 and SNMP protocols. Now I am planning to include SOAP as well. Looking at this scenario, I have the following questions:
1. Do I really need to support SOAP in JMX? The logic here is SOAP is already platform independent, so why not directly use webservices.
2. Which version of Axis can be used with any SOAP implementation in JMX (Axis/Axis2)?
3. Is there any commercially free connector available? If yes, how is the performance of this connector?
4. What will be the deployment scenario (since there is not much documentation available)?
Any inputs will be valuable.

Can you please help?So you've got some MBeans, and you want to expose them over as many different protocols as possible? No reason why you can't do that, if that's what you really want. Sounds like overkill, or a refusal to consider actual requirements, to be honest. The fact that JMX is at one end of the equation is pretty much irrelevant, it's all going to just be data as far as SOAP's concerned.

Questions on JMX and management-config

I was wondering if anyone can clarify the usage of management-config.
We've got a setup with managed-nodes=all and allow-remote-management=true (other params defaulted). We've got processes that occasionally ping the cluster (via a single node) to log performance statistics and to look for problems that might require intervention (across all nodes via remote management).
I'm trying to determine if the JMX subsystem is completely isolated from runtime cache performance.
1) Does the setting for the read-only flag impact performance in any way? If set to false, is there any sort of locking or synchronization that takes place when querying cluster nodes?
2) Do calls to JMX (and presumably the Invocation Service) share any resources with a Distributed Cache Service?
3) the Default management-config settings in Tangosol-coherence.xml point to the "Management" service - which is not actually defined elsewhere in the configuration file. Is this actually an implicit link to the Invocation Service?
4) Is there a single "Service Thread"? or does each distinct service have its own service thread?
Thanks in advance,
Dave

The performance impact of management is relatively small. The consumption is based on the information "read" (getAttribute/getAttribute) and the frequency of the poll. Polls of the same data element within 1 second will receive the same result for remote nodes.
The formula to determine the network consumption estimation formula for Coherence 3.3 on a single poll of the information is:
Estimated network bytes per poll =
Number of remote Node MBeans retrieved * 725
+ Number of remote Cache MBeans retrieved * 225
+ Number of remote Storage Manager MBeans Retrieved * 720
+ Number of remote Service MBeans Retrieved * 144
+ Number of remote Point to Point MBeans * (Number of Nodes in Grid -1 * 250)
Given the order N size of the Point-to-Point MBeans, It is not recommended to put that information in a loop for a large cluster.
1) Does the setting for the read-only flag impact performance in any way? If set to false, is there any sort of locking or synchronization that takes place when querying cluster nodes?
EW: The Read-only flag does not impact performance. There is no synchronization on read of the objects. Synchronization on update is on an attribute by attribute basis.
2) Do calls to JMX (and presumably the Invocation Service) share any resources with a Distributed Cache Service?
EW: The JMX calls are processed through the Management (Invocation) Service. This shares system (memory, CPU, network) resources with other services. The management information is not processed out-of-band and under extreme load performance will be impacted.
3) the Default management-config settings in Tangosol-coherence.xml point to the "Management" service - which is not actually defined elsewhere in the configuration file. Is this actually an implicit link to the Invocation Service?
EW: The Management service is a non-configurable Invocation service.
4) Is there a single "Service Thread"? or does each distinct service have its own service thread?
EW : Not exactly sure I understand the question. Each service has its' own "Service" thread and thread pool. However, there are some shared components at the TCMP (network) layer.
Hope this helps,
Everett Williams

Directory structure for servlets and webservices in one application

hi,
Can any one help me for creating servlets and webservices in one
application and deploying in Jboss 4.2.0.
I want to know exactly what is the directory structure for creating this
application and what are the additional .xml files for deploying this application.
if any one know this answere please tell the answere.

I figured out a solution - it's a problem of policies. In detail: Server1's codebase entry (file:) refers to the class directory of Server1's project. In the simple case of only Client1, which has no codebase entry, it works fine without a file permission on the side of Server1. In the complex case of Client1+Server2, which has to have a codebase entry (file:) refering to the class directory of the Server2's project on a separate machine, for exactly the same method call from Client1 to Server1 a file permission entry on the side of Server1 is needed for Server1's class directory. But WHY ???
It seems to be a little confusing with the codebase entries, many of the posts are contrary to others and to my personal experiences. Some comments given by Adrian Colley throw a little light upon some aspects. Is there anybody, who can explain the whole topic, when, why, and which part of RMI application deals with codebase entries, also in case of not dynamic code downloading ? May be there is also a reference into the java docs, which I didn't found up to now.
Thanks in advance

Making a call over HTTPS with LoadVars, XML.load(), and WebService - Yes or No?

Hello, do LoadVars, XML.load(), or WebService support HTTPS-based endpoints, Yes or No?
BACKGROUND
============
I've been trying to get a LoadVars to actually make a call to an HTTPS endpoint. There is nothing in the documentation that says it can't. I know that there's also XML.load() and WebService class, but from the looks of it they don't do HTTPS.
During my tests I have absolutely no issues with making calls to the same service over HTTP. When I change it to HTTPS I don't see HTTPStatus or even failures. Also, netstat on my server will show a connection being established with the endpoint when using HTTP but not when using HTTPS. I've also tried setting SSLVerifyCertificate to "false" in my Server.xml and after a restart of AMS it doesn't help, same symptom.
I've also googled and looked through all Adobe forum posts that I can find:

WebService Class - http://stackoverflow.com/questions/5619776/webservice-and-fms
The best I found from the posts above is a non-commital answer from adobe staff at https://forums.adobe.com/message/4938426#4938426 and a 3rd party person saying that Webservice doesn't work at http://stackoverflow.com/questions/5619776/webservice-and-fms.
All I need is an official supported/not-supported from the Adobe staff. Shouldn't be to hard after 5 years or so of ignoring the questions in the forum right?

Adobe, please provide some details to your current and possibly potential customers, in at least one of the many unanswered posts about making HTTPS requests from AMS.

BPM and Webservices

I'm new in using of BPM and Webservices
Netweaver version is CE 7.2 SPS03
I use Web dynpro to write a ap to trigger web service for start BPM process.
It took about 40 sec for waiting response when i trigger the synchronous web service.
And i get a exception "DEFAULT_WS_METADATA_DEST. The server response timed out"
But i check my process status, it is running ok.
When I tested for asynchronous web service ,I get quick response for it
Does this version only support asynchronous web service?
Do I need another configuration to use synchronous web service?

Hi
For process start you need a asynchronus web service (no output / response).
Also, you can use a synchronus one if you are aware of this: If you use a synchron web service, you have to model a parallel split at the beginning of the process and finishing one of both tokens directly. This way, a response is generated when the first token hits the end event and the rest of the process is handled asynchronus.

BPM 11g: JAVA API and Webservice API

Who knows BPM 11g: JAVA API and Webservice API?
Customer want to call BPM 11g between Heterogeneous systems, such .net framework. One way is use webservice API, I think, but where can find it? thank you

When you create a BPM application in 11g, you're actually creating a SOA composite application with a BPMN component in the composite. From within the BPMN editor, you can specify the interface (parameters) of each start node in the process. If you select a start node, look at the implementation tab, you'll see a properties group that lets you define the interface one property at a time, or by selecting an interface from the catalog.
By defining these properties you're also defining the shape of the Web Service interface that will automatically be created in the composite. If you switch to the composite view, you'll see your BPMN process with a wire to it from a Web Service that's generated from the interface defined in the BPMN editor. The naming convention is the BPMN process name with ".service" appended. When you deploy the BPMN process, the web service will also be deployed, since it's also part of the composite. From Enterprise Manager (EM) you can test the service and get the WSDL, which could be used by other applications (e.g. .NET) to start and interact with a process instance.
This is one of the advantages of the 11g architecture. The composite exposes services to consumers/clients. The implementation could have been BPEL, BPMN, a Mediator, Java/EJBs, or any combination working together. To the consumer, it's just a web service.
In case your next question was about security ... you won't see properties about security in the BPMN editor. You use Web Service Manager to apply security or other constraints to the web service endpoint.

SLD conf for JDBC and webservice

Hi,
I am coonecting to source and target via webservice or JDBC.Do we need any configuration in SLD for systems.Driver and webservice has all details to connect to source and target system.Please confirm me if I am wrong.

When you have complete tech details of the system, you can create a Business System for the same and import it into your ID.
In short, a Business System represents a physical system.
When you don't have complete info for the system, you can create a business service in your ID.It represnts an abstract service that makes connection to the source/target system.
The choice depends on our own.

Unable to add XML and Webservices Datasource in Crystal Reports

Hi,
when I am trying to add a Web service datasource upon clicking the XML and Webservices Datasource in Database Manager I get the following error.
Invalid Arguments Provided.
Details: Java server startup failure. Verify PATH (JDK), CLASSPATH, and IORFileLocation properties in the CRConfig.xml file. In addition, verify that you are using JDK 1.5.
I am using Windows server 2003 OS. Java is version 1.6. I tried the below things but none of them worked.
1.Edit the crconfig.xml file to add classpath and license information
2.reverted to java 1.5
3.uninstalled and installed the CR 2008 software. None of these worked. Please help.

Thanks Don but my issue is not proxy related.
I am not using a proxy though I am using a VPN to be in the network of the Webservice hosting server. Also, my problem is that I am not able to even enlarge the XML and Webservices Data source to add any xml or web service file let alone the one I want to.

EAI and Webservices

Which is the intersection point between EAI and Webservices?
Regards.

Hi Harmeet,
I hope its because ODI is an E-LT and OWB is ETL tools. As i said in the previous post E-LT approach needs less servers and provides good speed.

Compare weblogic SM and webservice SM in OES

Can you please tell me which one is the better one between the weblogic SM and webservices SM in OES.
If you have any link which will explains the difference please let me know

I presume you're talking about OES 11g. WebService SM has some limitations. I would advise to go with WebLogic SM and deploy webservice application in WebLogic Server and play with it.

Hi Ravi,
Jin has correctly explained.
Only two connectors are provided from SAP
JCO- for connecting java applications
>.Net connectors - for connecting >net applications
And SAP has provided these connectors bcoz these the two most popular technologies or framefork these days which are very common.
But In my previous examples , I try to explain the concepts only by giving .net as example.
Now for making you clear, No SAP connector is available for C++ for accessing RFC but C++ can access web services using XML and SOAP
Again Note these points.
RFC is SAP specific.
Used For----->
SAP applications- SAP applications
SAP Appl - Java Applications(Using JCO)
SAP Applications->Net Applications( using >NEt connectorprovided by SAP)
Web Service is open standard
Any Platform/Any Language to Any Platform/Language( which can understand SOAp and XML).

Problem in creating EJB and WebService using complex class structure

Hi All,
My requirement is like :
I have a class with very complex structure.
I have also used external .jars.
Now when I have created an EJB with a method's return parameter as above class.
But when I am creating a Webservice, it doesnot allow me to select this method.
Not able to configure why ?
Please Help.
Thanks.

Hi,
I have gone through your code and the problem is that when you create jar it takes a complete path address (which is called using getAbsolutePath ) (when you extract you see the path; C:\..\...\..\ )
You need to truncate this complete path and take only the path address where your files are stored and the problem must be solved.

Ejb 3.0 and webservices

Hello everybody?
Does everybody know if i can create a web service from an ejb 3.0 stateless session inside jdeveloper 10 g 10.1.3 (using a wizard for example)?
Thank you

It's almost too easy to need a wizard - try this:
Trhough your project properties add the JSR-181 Web Service library
In your session bean type @Web (at the top of the class or above a method) and you'll be prompted to import javax.jws.WebMethod (using Alt-Enter) then you can select the appropriate tag (@WebService for all methods to be published, @WebMethod at the individual method level, etc.)
Then deploy your EJB as normal and voila! See the deployed EJB and Web Service
