Exposing Java method as Web service

Hello,
I would like to know how can I make a Java Method expose as a webservice using BPEL.
I have created a java class To do some processing. I want to make this as a service. Is there any sample code to do this? Please provide any links..

If you used the Web Service Wizard the easiest thing to do is:
1. Delete the WS class - when prompted also delete all artifacts - you should now see your original class files. *
2. Add extra methods.
3. Regenerate web service using same parameters as previously (make sure you use the same namespaces).
(4. Apply any customisations you made)
*Occasionally this will not work and will not remove the references to the WS artifacts from the project file, in this case you will need to manually remove them from the project xml file.
You can also edit the project to make the classes visible (can't remember the exact steps for this, it's been a while), change the classes and regenerate services, however this will overwrite any customisations you have made, so is little different to removing the artifacts and regenerating.
Finally you can make the classes visible as above, updatethem and then manually edit the other web service artefacts (<name>-java-wsdl-mapping.xml,webservices.xml, oracle-webservices .xml, Interface, etc). This is a lot more tedious than using autogeneration.

Follow up to web services question: How do I expose java components as web services on iPlanet 6.0 app server?

My task - my company has several legacy PowerBuilder applications that access a variety of Sybase and MS SQL databases. Rather than re-inventing the wheel by re-writing these applications in Java, we would like to enable these applications to call java components (EJBs) that will provide new functionality. I would need a piece of software called CSXtend (from www.cynergysystems.com) to allow PowerBuilder to call a web service. However, I am not sure how to expose my business functions (EJBs) as web services on the iPlanet 6.0 App server. Thanks for all previous responses! Any additional info would be greatly appreciated! Mike

I have used Glue (http://www.themindelectric.com/products/glue/glue.html) to expose some of our stuff as Web Services. I recently found this on serverside. It's pretty good.
http://www.theserverside.com/resources/article.jsp?l=Systinet-web-services-part-1
I believe that the middleware they use can be plugged into IPlanet. There is also an article in the knowledge base on the IPlanet site.

Contivo Java class as web service

Hai,
We used the contivo mapping and from that generated one java class. We need to use it as webserivce.
With the help of Eclipse and AXIS( 1.4 ) made a try, and while making it as webservice , getting warning as The service class "Transform_source1_to_dest1" does not comply to one or more requirements of the JAX-RPC 1.1 specification, and may not deploy or function correctly.
In wsdl file also some errors are getting in namespace imports.
So please help me to solve this problem.
Can we use the Contivo generated java class directly as a web service ? for that which web service engine can be used?
Apache AXIS 1.4
JDK 1.5
Contivo Analyst 3.11.2.1.5
Thanks in advance.
Rgds,
Rajeev

Rajeev,
Contivo transforms can be invoked indirectly through two APIs, which have often been used for invoking transforms from web services. One API is called Transform and the other is called TransformAny. The Javadoc for both is distributed with Analyst, and the "Runtime Guide" is also distributed with Analyst.
Does this get you closer?

Error converting CFML arguments to Java classes for web service invocation.

Hello all.
I am working on writting a small application that will use a web service that is provided by our IVR (Angel.com). I am able to login, however when I attempt to do anything with complex objects, I get the error stated in the title.
It seems to be having a problem with the array, because when I remove it, or turn it into a simple string, i get errors about the function not being found. I am fairly new to web services, and especially dealing with complex data types, so any help would be much appreciated.
You can see my testing page at
http://webservices.fpitesters.com/AngelCalls.cfm
The WSDL I am using can be found at
http://www.angel.com/outbound/wsdl/OutboundCallService.wsdl
Here is sample code that does what I want it to do in Java / Apache Axis
http://www.socialtext.net/ivrwiki/index.cgi?java_sample_code
Here is a description of the function I am having problems with
http://www.socialtext.net/ivrwiki/index.cgi?placecall
And attached is my code.
     <cfset email = "xxxxxxxxxxxxxxxxxx">
     <cfset pin = "xxxxxxxxxxxx">
     <cfinvoke webservice="http://www.angel.com/outbound/wsdl/OutboundCallService.wsdl" method="login" returnvariable="login">
          <cfinvokeargument name="email" value="#email#"/>
          <cfinvokeargument name="pin" value="#pin#"/>
     </cfinvoke>
     <cfdump var="#login#">
     <cfset Token = login.getToken()>
     <cfdump var="#token#">
     <cfset CallItem.maxWaitTime = 100>
     <cfset CallItem.phoneNumbers[1] = "7632344306">
     <cfset CallItem.siteNumber = 100041>
     <cfinvoke webservice="http://www.angel.com/outbound/wsdl/OutboundCallService.wsdl" method="placeCall" returnvariable="call">
          <cfinvokeargument name="Token" value="#Token#"/>
          <cfinvokeargument name="CallItem" value="#CallItem#"/>
     </cfinvoke>
     <cfdump var="#call#">

If you are not initializing phoneNumbers as an array before setting
<cfset CallItem.phoneNumbers[1] = "7632344306">
it will be passed as a struct with a key of 1. This could cause your argument conversion error.
So:
<cfset CallItem.maxWaitTime = 100>
<cfset CallItem.phoneNumbers[1] = "7632344306">
<cfset CallItem.siteNumber = 100041>
Will result in
struct
MAXWAITTIME
100
PHONENUMBERS
struct
1
7632344306
SITENUMBER
100041
<cfset CallItem = StructNew() > 
<cfset CallItem.maxWaitTime = 100 >
<cfset CallItem.phoneNumbers = arrayNew(1) /> 
<cfset CallItem.phoneNumbers[1] = "7632344306">
<cfset CallItem.siteNumber = 100041>
Will result in
struct
MAXWAITTIME
100
PHONENUMBERS
array
1
7632344306
SITENUMBER
100041

Add java classes as Additional Classes to web service and JAXB 2.0 usage

Hi,
I start using JDeveloper 11g TP3 to create web service. I encounter two problems.
1. I created a schema file as the following,
<schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://FromWSDL/" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:tns="http://FromWSDL/">
<xsd:complexType name="sayHello">
<xsd:sequence>
<xsd:element name="arg0" type="xsd:string" default="Tommy"/>
<xsd:element name="arg1" type="tns:arg1Enum"/>
</xsd:sequence>
</xsd:complexType>
<xsd:simpleType name="arg1Enum">
     <xsd:restriction base="xsd:string">
     <xsd:enumeration value="preserve"/>
     <xsd:enumeration value="replace"/>
     <xsd:enumeration value="collapse"/>
     </xsd:restriction>
</xsd:simpleType>
<xsd:element name="sayHello" type="tns:sayHello"/>
<xsd:complexType name="sayHelloResponse">
<xsd:sequence>
<xsd:element name="return" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
<xsd:element name="sayHelloResponse" type="tns:sayHelloResponse"/>
</schema>
then I used TopLink/JPA-->JAXB 2.0 Content Model from Schema, I got four java files: Arg1Enum.java, ObjectFactory.java, SayHello.java, and SayHelloResponse.java.
After, I create a java class with @WebService and @WebMethod annotation. Right Click on the web service class,
select Web Service Properties-->Additional Classes, I added the four java classes. but there are error message for SayHello and Arg1Enum
"the type SayHello cannot be serialized into XML and no custom serilizer has been defined for it"
2. In JDeveloper, I create Java model from the above schema, then reverse the steps, create a new schema from Java Model, the original schema and the schema from Java Model are not same, especially for "defaultValue" and "required" fields for the custom element(SayHello and Arg1Enum).
Any help will be appreciated

First what you mean by "deploying classes as web services"? Chances are you
can do it with something like Glue from The Mind Electric ... but chances
are that you don't want to. What are you trying to accomplish?

Hi, can WebLogic deploy simple Java classes (not EJB's or JB's, just

The WebLogic installation has one measly web services example, and it's an

Benefits of exposing function module as web services

Hi All,
We are developing a case study about exposing function modules as web services.
Those web services would be later used for integration to SAP box with a Java application.
Kindly help me with the pros and cons of exposing function modules as web services when compared to SAP PI. Also please do quote some examples, wherever possible.
Thanks,
Varun

Hi Varun,
Pros--->
1)Exposing FM as Web Services is indeed a good choice when you want service consumer to be platform and language independent.
i.e it can be consumed by .Net, java or any other language.
2) You are moving towards SOA
3) Composing Business Process by concatenating different functional modules is easy.
4) Complexity is less while consuming services Java, CAF etc.
Cons----> Performance for Web Services is comparatively less than JCo .
If you are bringing PI in between landscape, you are increasing one more layer of middleware which would also hit performance.
The benefit which PI can give is monitoring your company wide integrations at one central point when you have huge systems.
Hope this helps.

Exposing RFC as a Web Service

Hello All,
I am working on a SOAP to SOAP (Backend as ECC where I am exposing an RFC as Web Service). Once the Web service is generated for RFC and the WSDL is imported in PI, I can see that all the fields in different nodes become mandatory.
Is it how normally Web Service for BAPI works or can this behaviour (mandatory / optional) be controlled ?
Also when I execute the end to end scenario via SOAP UI, I don't get any error back but also neither get the Return table nor the Sales Order NO. I am using the BAPI BAPI_SALESORDER_CREATEFROMDAT2.
Can it be because of no COMMIT (The BAPI uses external commit although this reason seems less likely as executing a RFC wo any commit atleast gives me a Sales Order no) ?
How can this call be analysed in backend ECC system ? (As I assume that messages will not be visible in SXMB_MONI as explained by the Harald's thread below. I am currently in process of getting authorization of SOAMANAGER logs but wondering how it'll help?
Thanking you in advance.
SOAP to SOAP scenario: XML messages not visible in SXMB_MONI

Hi,
Please see the SOAP ststud..
http://<host>:5<sys#>00/mdt/amtServlet
also you might check any error logs.
The error is because of invalid xml document. So check the validity of the xml message ie. after first mapping i.e Req mapping.
For this you can refer this -

What the mechanism of the Java Proxy for Web Services in WLS 8.1

Hi, all;
I try to find out how the java proxy of web service in weblogic server 8.1
works. Suppose I use the java Proxy of a WebSerice in a client application whatever
whithin or outside the application of the web service, does the proxy actually:
1. translate my java arguments objects in XML to create SOAP msg,
2. then send the msg across the network, and web service also response SOAP msg,
3. then proxy translate it into return value of the method call ?
If that is true , the Java Proxy seems very inefficient, right?
Can any body tell me how the proxy works ?
regards,
shannon

Hi Shannon,
The type of proxy I'm familiar with is at the http connection level and
associated with the networking properties in the JDK, See:
http://java.sun.com/j2se/1.4.2/docs/guide/net/properties.html
Your question may be related to JWS proxies, See:
http://edocs.bea.com/workshop/docs81/doc/en/workshop/guide/howdoi/howUseTheJavaProxyForAWebService.html
You may want to ask this question in the workshop newsgroup.
Hope this helps,

Exposing Inbound Interfaces as Web Service

Hi,
when it comes to expose XI interfaces as web services, the XI documentation quotes:
"Sie können sowohl von Outbound- als auch von Inbound-Message-Interfaces WSDL-Beschreibungen erzeugen."
-> i.e. Inbound interfaces can be exposed as web services.
But the web service definition wizard expects the quotation of an outbound interface. So am I right when I say that I always need an outbound interface? If yes, why is it possible to expose inbound interfaces???
Cheers,
Heiko

Hi,
no, inbound interfaces can only call web services
that are exposed on some other web servers
only outobund XI interfaces can be exposed as web services
(in this case XI acts as a web server)
and other applicaitons can call this outbound interface

Is it possible to invoke a Java class from Data Services 4.0?

Is it possible to invoke a Java class from Data Services? I have a query transform with a varchar column which I want to run an external java class against to encrypt the string value. In the Management Console, I created an adapter of type TestAdapter and referenced my jar file in the Classpath section, but when I create a Datastore of type Adapter I can't import any functions related to my java class? It seems like I need to create a new Adapter type similar to the TestAdapter with the 'Adapter Class' set to my java class? I can't figure out how to do this - which is the correct approach and is there some documentation available? thanks!

First u nees to imoprt the class which u are doing right
then u need to call the function of the class , and then you can put the value in a string .
DbCon.function()
String data = DbCon.db;
where db is a string in DbCon
