WSGEN question on WLS 6.1 / Web Services

I am just starting out with Web Services and I am trying to
build some examples from the WebLogic 6.1 Bible step-by-step
using Ant 1.3.
I get this error when I execute Ant with the -verbose option:
allen @ olc301 [5] ant -verbose rpc.ws

Common solutions are to use taskdef to declare your task,
or, if this is an optional task, to put the optional.jar in
the lib directory of your ant installation (ANT_HOME).
Can anybody help me ? I see several similar questions in the
newsgroups but no answers - I am missing something simple I
think !!
Thanks in advance -

Don, thanks for the reply !
I was using a different version of Ant and using the BEA version helped. Maybe
this is something I missed in the documentation ?

Are you using the version of ant that comes with WLS (which has the
taskdefs in the defaults.properties file) or your own copy of ant?

Are the WLS 9.1 Web Service Ant Tasks ready for prime time?

I am trying to create a Proof of Concept (POC) for Enterprise and B2B Services at Wendy's Int'l, Inc.
As part of this POC, I created a WSDL for an in-house service and then used the wsdlc and jwsc Ant Tasks to translate this WSDL to Java classes and ultimately (I hoped) a deployable services.
In this document, I describe the issues I encountered setting up what I consider to be a simple POC.
I'll try to attach my WSDL file and build.xml so you can follow along.
I'll also try to attach my CSS file so you can compare how the generated WSDL appears in the Browser to the way I want it to appear.
If attachments are not allowed on these forums, then I will wait and see if there is interest in those documents before I paste them under this topic.
Some preliminary information about my environment.
Environment:
 Windows XP Pro SP2
 WebLogic 9.1
 Java 1.5.0_04
Service Name:
 AppRelease
Note: If I modify my WSDL (perhaps to add a new Operation or to change the definition of an element) and run wsdlc again, the AppReleaseSOAPPortImpl.java file is overwritten For this reason, I implemented my service logic in a class called AppReleaseServiceImple.java.
Now, for the issues.
1. Bug:
In the WSDL generated by wsdlc, the wsdl:part child of the wsdl:message tag is erroneously prefixed with a colon.
This occurs whether or not I specify a prefix for the http://schemas.xmlsoap.org/wsdl/ namespace.
Work around: Extract the wsdl from the jar file, fix it and add it back into the jar.
2. Bug:
In the WSDL generated by wsdlc, the wsdl:input and wsdl:output children of the wsdl:operation child of wsdl:portType tag are erroneously prefixed with a colon. Like 1 above, this occurs whether or not I specify a prefix for the http://schemas.xmlsoap.org/wsdl/ namespace.
Work around: Extract the wsdl from the jar file, fix it and add it back into the jar.
The error message generated by Bugs 1 and 2 is not helpful in diagnosing the problem:
[jwsc] Error at line:46 col:7 ':' expected [?! -- [CDATA[ ]
3. Bug:
In the WSDL generated by wsdlc, the documentation elements have all of my html elements stripped out, as well as my xhtml and wsdl namespace references. This completely negates one of the best features of the documentation tag, being able to present the WSDL in a browser as a nicely formatted, human friendly document which is also the underlying WSDL that can be viewed when the person views the source document.
I label this as a bug because it greatly reduces the functionality of the resulting WSDL.
4. Annoyance:
The WSDL generated by wsdlc has all of my comments stripped out, except the comments in the xsd:schema section of the wsdl:types element. I would prefer that all my comments be left in the WSDL, but if comments must be stripped out then I think all of the comments should be stripped out.
5. Annoyance:
The WSDL generated by wsdlc has my CSS specification stripped.
Work around: I donâ€™t know if adding the CSS back will do any good because I have not yet created a deployable service (see the last issue below).
6. Annoyance:
The WSDL generated by wsdlc has different namespace prefixes than the ones I specified for my application's namespace and for the http://schemas.xmlsoap.org/wsdl/soap/ namespace.
Work around: Perform a find/replace on namespace prefixes "s0" and "s1" to return them to my prefered values.
Another thing I can do at this point is simply replace the generated WSDL in the jar file with my original WSDL. This would address issues 1 thru 6 above.
7. Annoyance:
The java source files created by wsdlc are put into a jar file. This makes it annoying when working within a traditional IDE like Eclipse because there is no way to reference the source files within the jar as working source.
Work around: Extract the source files from the jar and identify the resulting directory structure as part of the source structure of the project.
8. Bug:
The jwsc task complains if the same parameter name is used in multiple operations. I received the following Errors from jwsc:
[jwsc] C:\IDE\workspace\Acre-WL9.1\AppReleaseSOAPPort.java 0:0
[jwsc] [ERROR] - Parameter element "{http://acre.services.wendys.com/AppRelease/}garRequest" is not unique across document/literal bare WebService.
Since the operation names are unique, I see no reason to also require uniqueness in the parameter names used by those operations.
Work around: Use unique element names for the input parameters of the services operations.
9. Bug:
Once items 1, 2 and 8 above are taken care of, jwsc fails with the following error:
java.lang.AssertionError: java.lang.ClassNotFoundException: weblogic.j2ee.descriptor.ApplicationBeanImpl
This seems to be due to the weblogic.jar file not being in the System Classpath.
However, I should note that when I set verbose="on" and debug="on" in the jwsc ant task, there was a message from the task which stated "[jwsc] [search path for class files: [big freakinâ€™ jar list]". In the big freakinâ€™ jar list, I did find weblogic.jar and weblogic.jar has the required ApplicationBeanImpl. This indicates to me that the jwsc task does not fully honor either its classpathref attribute, nor an embedded classpath element.
Work around: Make sure the weblogic.jar is in the System Classpath.
10. Bug:
I fixed bug #9 by running a setDomainEnv script and then ran my ant task. This time I received the following output:
ant build-serviceBuildfile: build.xml
build-service:
[jwsc] 1 JWS files will be processed.
[jwsc] Processing JWS: C:\IDE\workspace\Acre-WL9.1\src\com\wendys\services\acre\AppReleaseServiceImpl.java
[jwsc] JWS: C:\IDE\workspace\Acre-WL9.1\src\com\wendys\services\acre\AppReleaseServiceImpl.java Validated.
[AntUtil.deleteDir] Deleting directory <some temporary directory>
BUILD FAILED
java.lang.ExceptionInInitializerError
At this point, I am completely stymied about how to proceed.
I wonder what new issues await once this 10th issue is addressed.
Really, is this tool set ready for prime time?

Sorry to hear you are having so many issues with using the WLS 9.1 web service Ant tasks, inside of Eclipse.
I generally create a User Library for the couple weblogic jars needed, and use it (the User Library) in my Eclipse projects that I create JWSes in. 
I also have a separate WebLogic Library in Eclipse (actually 2 libraries since I work with WL 8.1 and now WL 9.1). As you may know, one of the long-standing issues with the Ant integration within Eclipse is the fact that Ant, being an External Tool, does not receive the Project-specific Paths/Libraries. However, since most Java-relevant Ant tasks can take classpath and classpathref attributes, this is usually not an issue. In the case of the BEA-supplied wsdlc Ant task, it is apparent from the verbose/debug console output that wsdlc can see the jars in its classpathref, but it ignores those references when resolving class references and instead only uses the system classpath.

I've only needed the weblogic.jar and xbean.jar, not all the ones you mentioned in an earlier thread of this post. 
I have not tried to winnow down exactly which jars are required. I simply included all the jars that exist and were added to the system classpath by the setDomainEnv.bat file created by WebLogic 9.1.

Afterwards, I create an Ant Builder to build the JWS Web Service EAR, as opposed to fiddlin' with Eclipse. 
I too use Ant to build my deployable archives. Eclipse is simply my IDE of choice. I validated that all the issues I listed occurred when running Ant from the command line.

If you are interested in how I do it, send me an e-mail (to [email protected]), and I'll send you a zip of one of these JWS projects. The build.xml script for the project, takes care of a lot of the "annoyances" you mentioned, one of which I think is not accurate. I have never had a situation where the wsdlc Ant task "overwrote" my XXXImpl.java file.. 
Since I'm doing a POC to determine how we want to proceed with developing Web Services and an SOA in general, I tried to perform the same tasks using Axis 2 1.0, the WebLogic 9.1 tools, and XFire 1.1. Overwriting the Impl class is a common failing in the tools which take a WSDL and create Java source files for all three frameworks.

Try my scenario. Add another operation to an existing WSDL, and run the wsdlc Ant Task. The old IMPL class will be over-written.

Because of this, I have a separate Impl class and I make sure that all its methods and annotations match the methods and annotations in the Skeleton Impl class created by wsdlc.

Maybe that's because I use the <exec> Ant task with jar.exe (the xvf options) in my build.xml, to only get what I need out of the .jar/.zip the wsdlc generates. I'm typically only interest in the interface class that my XXXImpl.java file needs to implements, because I use XMLBeans for the input args (and return values) of my web service operations. 
Perhaps. I am not using XMLBeans in any of the three frameworks because the resulting service seems to be lighter-weight in all three frameworks if XMLBeans is not used. I'm sure there will be scenarios where XMLBeans is preferred, but I have not encountered that case in this POC.

Mike Wooten

Problems - WLS 10.0 web service client

I'm having a few issues with WLS 10.0 web service client.
 I generated a service control from the WSDL. The service is provided by a 3rd party (non-WLS) at another company. I generated the control within my web project and it's deployed as part of the web application. I experience the following problems with the service control API:
 1) The methods setKeyStore(), setTrustStore(), setClientCert() all seem to be ignored - the server always uses the values set in the server's environment definition. Note - the setEndpointAddress() seems to work.
 2) The client request does not set the 'Content-Type' HTTP header correctly (it's set to text/html) - I have no way to override this via the service control API (that I can see).
 3) I don't see any way/place to turn on more detailed tracing of what's going on internally with the service control invocation - is there a way to enable a detailed trace log of what is happening within the service control?
 Note: I'm able to call the web service via the test client (after importing the 3rd party server cert into my local cacerts).
 Thanks,
 [email protected]

Thank you for the reply..
But im still geting the same error. I have tried to include all the libraries in JWSDP pack but still.. I have managed to narrow down the place where the error occures.. It actually happens when I try to get the WebService Client Servant which is located in the package LSC:
---> LSC.LWServiceGenClient.LWS_Impl service = new LSC.LWServiceGenClient.LWS_Impl();
LSC.LWServiceGenClient.LWSServantInterface lagerServiceServant = LSC.LWServiceGenClient.LWSServantInterface_Stub)service.getLWSServantInterfacePort();
return lagerServiceServant;
Could something be wrong with the way I package the Jar? I'm using Sun One Studio and have tried including the 5 packages the application consists of; I have tried including just the files; moving the main class to <root>.. Still same problem..
Or could there be some different fundemental thingy I have forgotten ??
thanks

Looking for WLS 7.x Web Services interoperability information

Does anyone know of any published reports on compatibility when non-WLS clients
access a WLS web service? I’m completing some tests with clients created using
the Java Web Services Developers Pack but I’m more interested in how it also does
with other vendor implementations (Microsoft, IBM, Apache). I’m also interested
in whether WLS 6.x clients can access WLS 7.x web services. I haven’t seen BEA
referenced very often on the interoperability sites. Has BEA published any information
on their compatibility? Has anyone else published information on this?
Thanks,
Dave

The server seems to be OK (tried intra and internet) ... yes it's normally up.
Please try again and let me know of any further problems.
Thanks,
Bruce

The workaround is to change the complex data types

Attachment in WLS 7 sp2 Web Service

Hi, I'm trying to send to a Web Service in WLS7 sp2 SOAP message with attachments. My problem: when I don't add any attachment to SOAP message all go OK, but when I add an attachment with the "href" attribute in an element of the message (I need do it because I use the MM7 protocol of 3GPP), WLS7 donÂ´t accept my message and tell me: "The ID referenced by ..... is unknow". The Content-ID of attachment is equal to value of the href attribute.
Please, I need help with this!! If anyone knows any URL or sample code that can help me, please, reply to this post.
Thanks and sorry, my english is not very well.

Currently there is no option to turn off security check.
I think you can use a servlet filter mapped to the URL
of your service, instead of a proxy servlet?

Hi!
We need to implement authentication using our own methods, and theauthentication
information is provided to the web service implementation in a basicauthentication
header. The problem is, that the servlet
weblogic.webservice.server.servlet.WebServiceServlet, which handles webservices
in
wls 7.0.sp2, always attempts to perform authentication, if the header ispresent.
Is there any way to circumvent this, because we want to implementauthentication
on our own?
I already know two workarounds:
The best would of course be to implement a custom security realm for ourown
authentication system. This is not an option, implementing an own security
realm is overkill for this specific web service.
The other way would be to route the requests by way of a custom servlet,which
would
remove the basic authentication header, and put the authentication info incustom
headers, such as x-auth: <user:password>, or smthng similar, and aftersuccessful
authentication, make a call to bea's servletweblogic.webservice.server.servlet.WebServiceServlet.

But still, I'd like to know if there is any way to tell bea's servlet toignore
the basic
authentication header?
Oh yeah, by the way, this is URGENT, as always. (really!! ;)

Simple question re invoking non-WebLogic web services

I have a very simple question that I haven't been able to resolve elsewhere.
I need to invoke 3rd-party SOAP interfaces from my WebLogic 6.1 client EJB. All
the Bea documentation I've found refers to invoking "WebLogic Web Services" and
speaks of downloading the client.jar -- however, in my case it's not a "WebLogic
Web Service" I'm invoking, it's a non-WebLogic web service.
Does WebLogic 6.1's WebServiceProxy (or other tool) allow this? Or must I use
some other SOAP tool such as Apache Axis in this case?
Thanks.
Cheers,
allan

Could this interopability problem have something to do with a problem
I'm experiencing on 61.sp3?
I have an EJB that accesses SOAP services on a Tomcat server. The SOAP
service sends back a SOAP exception which is correct in what I am asking
in to do. However, the weblogic app server is returning a SOAP
exception to my EJB rather than passing the SOAP exception to the API
that I am using to make my SOAP calls.
Has anyone seen something like this?

Note that your best bet, if possible, is to use the JAX-RPC
APIs within WebLogic 7. The SOAP support in WL6.1 has
interoperability issues.

Does WebLogic 6.1's WebServiceProxy (or other tool) allow this? Or must

Questions on using a SOAP web service's data in a Crystal Reports report

I'm attempting to create a report using CR 2008, accessing data from a SOAP web service. I've run into a few problems, and need some advice.
1) CR doesn't seem to support WSDL files that use relative URI imports (for example, I have a relatively complicated WSDL file that imports other WSDL files and schemas using relative URI locations). To solve this problem, I have downloaded all of the files to my local hard drive, and changed the "location" attributes to point to local files. Is there any other solution to this problem?
2) CR doesn't seem to support circular references within schema files. To solve this problem, I have removed circular references from my local schema files. Of course, my actual web service will still potentially return data structures with these circular dependencies. Is there any other solution to this problem?
3) CR doesn't seem to support request documents that allow for arrays of elements. For example, my schema allows the user to specify an array of Instruments that should be returned by the web service. In the meantime, I have changed the schema to only specify single instances of the Instrument element in the request. Is there any other solution to this problem?
4) CR doesn't seem to support empty values for optional attributes that are specified in the schema. So, when the "Enter Values" parameter form appears, I am required to enter values for these attributes, even though they are listed as optional in the schema. To avoid this problem, I have commented out the optional attribute values in the schema. Is there any other solution to this problem?
5) When the schema specifies that a value is based on a restricted simple (string) type, the CR parameter form shows a drop list with ellipses (...), but the drop list does not contain the enumerated types specified in my schema. Instead, I must manually enter a value. Do you know of any reason why the drop list is not populated?
6) The SOAP response document from my web service is relatively complicated. So, in the "Data" page of the Standard Report Creation Wizard, each and every XML element level of the response document listed in the schema is shown as a separate entry. If I choose just the top level element ("fetchInstrumentSetResponse"), then very little data is shown on the next page of the wizard (only the ID attribute). But, if I select each and every element type from the response document, CR prompts me for the request document parameters for each row I have selected (I see the same form 30+ times), even though there really should only be a single SOAP request to the web service to return this response document. It seems to be treating each of these elements as a separate "database table", with a different query string for each. Am I using this feature incorrectly?
If you can point me to somewhere in the documentation that handles this in more detail, that would be great (all I could find were the step-by-step instructions on how to connect to a web service as a data source).
Thanks!

Quick questions on the topic of Web Services and EJB POJOs

I have been reading about Web Services and the data types that are aloud as operation parameters and return types. I was wondering what the standard practice for return types; is it to use the Entity classes straight and customize the WSDL instead of letting the EE container do it (avoid cyclic problems in the schema that can occur when using entity 1-to-many and many-to-1 mappings) or; is it to off load the data into a DTO/VO/Bean and let the EE container take care of all the schema mapping for the WSDL? I look at the EE tutorial and bought a EE book both use very basic examples that do not include connecting to a database or using EJB3 for the data store.
Thanks for any information

Newbie question about the viability of web services.

Hello All,
I have never dealt with web services, and have only cursory knowledge of the technology, so forgive my ignorance in advance.
I have a situation that I wonder if Web Services might help me solve.
I have built a Java/JSP application that resides on a server that is inside our firewall. It has been successful, and management wants to make the data and functionality available to our customers outside the firewall.
The problem is that our organization tightly controls the "public" applications. And the UI for my system does not meet their standards. Nor will they punch a hole in the firewall to allow access to my server.
The solution we have been working on is to create a new UI using their approved methods, and copy the needed java classes to the "public" server.
As you can see, if I do this, I will have to maintain two instances of the same class on two different servers.
Can I avoid this by using web services to make those classes available to other applications from my internal server?
Thanks in advance for your help.
James.

The solution we have been working on is to create a
new UI using their approved methods, and copy the
needed java classes to the "public" server.
As you can see, if I do this, I will have to maintain
two instances of the same class on two different
servers. Okay, first, yes - webservices can help you if you MUST maintain two seperate UI's for some reason using the same backend data code or if you want to provide a datafeed only to your external users. It will take care of having to maintain seperate but identical class files, but it will create other overhead such as interfacing the existing files and the like, but if you must enable the UI then you will have two versions of this to maintain. If you are looking to just enable the data feeds and not the UI then it would seem a very logical fit.
If you must maintain the UI, then why can't you convert your app over to the approved UI and host it on the "public" server for all users (internal and external)? Then you only have one set of data to maintain - period and webservices aren't necessary. If you proceed with either your current implementation or even with a webservices based implementation, you will have at least two seperate UI's to maintain as well as whatever the resulting support code - be it webservice interfaces to existing code or replicates of existing code - to also maintain.

Short question about networking, Threads and web services..

Lets say I got 2 classes, Midlet A and Thread B.
I created Thread B because web services (jsr-172) uses networking and It has to be done in a separate thread other then the Midlet A.
So, in Thread B, I have the run(), where I do all my stuff, and some getSomething() methods.
I need to have run() complete before calling getSomething(), so I used something like this in Midlet A:
while(true){
if(b.isAlive())
getSomething();
}Problem is, Thread B only runs to completion when I don't call b.isAlive(). (I know from System.out.println I placed in it) When I do use any methods like wait() or join() or isAlive(), Thread B stops at the web service call.
I really don't understand what's the problem. I've tried various ways to only call getSomething() when the thread finishes running, but all of them made my WTK emulator hang at the part where it asks for permission to access the network.
If I don't use getSomething(), which is the purpose of starting the thread in the first place, it runs fine in the emulator and doesn't hang anywhere. Oh the irony.

Bump!
Anyone got even half a clue what's wrong? =O
Hmm. I think that having the midlet wait for the thread causes the midlet to hang because the thread will then wait for the midlet for permission to access the network, but the midlet is waiting for the thread to finish it's code. Damn.

Question about the distribution of web service or servlet

Hello,
I don not know how to distribute a web servcie or servlet on the web server. I can only use this web service with the open state of the glassfish. If I close the glassfish server, the servlet cannot be accessed.
I just want the web service or the servlet to be disributed on the web server. Web service and the servlet are available when the web server is on.
anybody can help me?
thank you in advance.

Licensing question of OAS 10g with web services

Does it cost anything extra to run/manage/secure web services built with jdeveloper 10g running on OAS 10.1.3?
thanks,

Hi Shay,
I have followed exactly what the tutorial
http://www.oracle.com/technology/obe/obe1013jdev/ws/wsandascontrol.htm
explains. But at the end of the wizard , I cant select the methods for the web service to expose. When i click whynot ? button it says the the validity of the methods is not correct and there may be compilation errors. My JDeveloper is uptodate . When I selected Oracle service in the Web Service type selection of the wizard , it did everything and exposed methods, generated wsdl .. etc..
Can you please tell where the problem is ?

Designer beginner's question: How to populate form with XML web service output?

sorry, here is yet another Adobe Designer beginners question: My form uses a webservice data connection which returns an xml-string like this: <?xml version="1.0" encoding="utf-16"?> <CurrentWeather> <Location>Sion, Switzerland (LSGS) 46-13N 007-20E 481M</Location> <Time>Apr 26, 2007 - 09:50 AM EDT / 2007.04.26 1350 UTC</Time> <Wind> from the WSW (240 degrees) at 15 MPH (13 KT):0</Wind> <Visibility> greater than 7 mile(s):0</Visibility> <SkyConditions> partly cloudy</SkyConditions> <Temperature> 80 F (27 C)</Temperature> <DewPoint> 46 F (8 C) </DewPoint> <RelativeHumidity> 30%</RelativeHumidity> <Pressure> 29.88 in. Hg (1012 hPa)</Pressure> <Status>Success</Status> </CurrentWeather> What is the simplest and recommended way to extract the element fields to my form? Thank you very much an kind regards, Hans Grund

The question is still unanswered!
Let me give some details and break up the problem
in more specific questions:
- In Designer 8.1 I click new data binding --> wsdl -->
http://www.webservicex.net/globalweather.asmx?wsdl
A message box comes up and says "cannot load wsdl file"
==> 1. Question:
Why maybe refuses Designer to load the http-wsdl,
although this option is explicitly allowed?
- When I save the wsdl to a file, Designer loads it
without any problems. The web service uses two input parameters
(CountryName and CityName) and returns an xml-string GetWeatherResult)
like the one in my first posting. I drag these fields from the binding view to my form, and it runs ok!
- THE PROBLEM IS, THAT I NEET TO EXTRACT THE ELEMENT FIELDS
FROM THE RESULT XML-STRING!
==> 2. Question:
How to extract xml element fields from wsdl output into a form?
- I tried with eclipse and XmlSpy to build a modified wsdl file
with structured output definition, so that the specific element fields
show up in the data binding view and are usable to my form,
and the modified wsdl maps consistently to the web service result string.
So far without success: In the PDF -preview or Reader-
when the wsdl-binding is executed and the web service output
should show up in the result fields, just nothing happens.
==> 3. Question:
Can this strategy to provide a "modified wsdl" possibly succeed,
and how?
==> 4. Question:
Is is possible -and how?- to check whether an xml string
is valid as web service output against the wsdl-definition?
==> 5. Question:
How to debug a web service connection with Designer?
- Finally I tried to find a way to load the result xml-string
into a local var in the script editor and parse it, much like:
var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.load(DataSet.MyForm.GetWeatherResult.rawValue);
==> 6. Question:
Is it possible -and how?- to use a framework like dotnet?
How to utilize SAX or DOM in Designer?
Many thanks and appreciations for your help!!
