JDeveloper / Web Services Challenge

Last Fall, Oracle offered a JDeveloper / Web Services challenge. It was a simple task that led the developer to build a simple java app to consume an Oracle supplied Web Service based on the SCOTT/TIGER schema. After submitting the correct response from the web service, Oracle promised a free Oracle Press Book. I supplied the response, selected my book and got a confirmation email from Oracle indicating that, once released, I would recieve my copy of the JDeveloper Handbook. To date, I have not received the book. Any Insights?
Thanks.

You are in fact a valid entry and should have been sent a book ... we are following up with the publisher to find out why you did not receive the book. The books were mailed out in December and January.

Web Services Challenge

Greetings,
Hello, I am a first year college student at UCSD and I am also a graduated member of the Oracle Internet Academy, a high-school program that teaches Oracle. I am interested in entering the Web Services challenge and possibly working with other Oracle professionals/students. If anyone is interested in working together on a project, or collaborating on ideas feel free to email me at [email protected] Thanks

Jdeveloper- web service- can't produce wsdl for java List

Hi-
I think this is a jdeveoper bug. It looks like the same bug as #4706306 in Jdeveloper 10g bugs.
There is a workaround suggest to use additional classes in the web service. But it does not work on 11g.
Details of the problem ........
I am trying to create a web service and client using jdeveoper 11g.
For some reason, the wsdl generated from the jdeveoper is incorrect. My java classes used List.
Apparently, jdeveoper does not like List . I can reproduce the problem using three files as attached.
the files are 1)Baby.java, 2)Papa.java, and 3)MyCall.java. The webservice is MyCall Class and the web method is getPapa().
After I created the web service and its wsdl, I then used the wsdl to create a client. then files are generated from the
wsdl for client . One of the file as in 4)Papa.java has a wrong List<Object>. It should be List<Baby>.
I can't move forward because of this problem. If any one can help, I'll be very appreciated.
Thanks!
Jason

Try using Collection instead of list so:
Collection<Baby> babyList = new ArrayList<Baby>();

JDeveloper & web services problems

I've recently installed jdeveloper onto winXP pro from the jdev9i_902.zip download and installed to D:\jdeveloper. Following the instructions I also installed JDK1.3 to D:\jdk1.3.1_04. I ran the setup for oc4j.
The problem I have is that when I followed the "Publish a stateless Java class as a Web service" tutorial, everything goes well until I run it. The errors produces are (taken from the tcptunnel output):

The main section that concerns me is "Invalid class file format in E:\Program Files\Java\j2re1.4.0\lib\rt.jar(java/lang/Object.class). ", why is it using this?
Any feedback on this is appreciated.
Dave

Hi Dave and Xuemei
I'd like to try and help you on this question. Can you confirm the following for me:
Did you download jdev9i_902.zip - the complete install or jdev9i_902_base.zip - the base install?
Dave, in you mail you say you have downloaded the complete install. If this is the case, then you did not need to install JDK1.3 and change the SetJavaHome variable. If you now comment out that variable then JDeveloper should use its shipped JDK1.3
The error message seems to indicate that a JDK1.4 version is being picked up by your system at runtime. Can you check if your classpath is set to this E:\ProgramFiles... directory. If so, can you try removing it (save it first!)
JDeveloper is certified against JDK1.3.1_02

JDeveloper Web Service Client/Proxy Basic Authentication

Hi I recently migrated a 10g Web Service to an 11g Web Service that uses basic authentication.
I then generated the client/proxy using the WSDL for my consumer application in JDeveloper 11g. however I cannot find any functions that will allow me to set the username and password to access the web service.
For instance, in 10g Client, I simply had to this:
myPort = new SoapHttpPortClient();
myPort.setUsername("username");
myPort.setPassword("password");
I am not sure how I do the same in the generated Web Service client in 11g.
Thanks in advance.

Thanks Frank. I was able to get it to work!
I did google it but I always add "jdeveloper 11g" in my searches so that must be why this did not come up. :) Thanks again!

JDeveloper "Web Services" tutorial new version needed

Hi everybody,
I'm studying web services now.
I've tried to follow "Publishing, Consuming, Deploying and Testing Web Services" JDeveloper tutorial (http://www.oracle.com/technology/products/jdev/collateral/tutorials/9050/mvcmodel_webservices_tut.html), but I've failed. Tutorial seems to be too old. I've got problems with generating web service and so on... This "End2End" web service demo (http://www.oracle.com/technology/products/jdev/viewlets/10g/WS_End2End_Demo_viewlet_swf.html) is too old as well...
Are there any more web service tutorials (preferrably online) for JDeveloper 10.1.3 except "building simple application"?

I tried to follow "Building a JAX-RPC Web Service" (http://www.oracle.com/technology/obe/obe1013jdev/unitedloan/unitedloan.html#p) tutorial, but I've got problems with steps 2,3,4.
Step 2 output: "Could not canonicalize 'P?↕' (The filename, directory name, or volume label synt
ax is incorrect). From system property java.library.path.
Enter an admin password to use:"
I enter password "welcome" as it is said in tutorial, but then step 3 causes problems.
Step 3 output: "Could not canonicalize 'P?↕' (The filename, directory name, or volume label synt
ax is incorrect). From system property java.library.path.
05/08/16 09:24:05 *** (CRITICAL) Tue Aug 16 09:24:05 EEST 2005 [Thread[OC4J Launcher,5,main]] setConfig

Step 4 fails because "test connection" fails.

Oracle9i Jdeveloper Web Services Deployment Descriptor

hii,
i have created a web service in oracle9i jdeveloper. It is running. But I need to define a handler for this web service to handle multiple attachments. But whenever i give the handler chain in web.xml, the handler is not invoked. Also it does not allow me to change the deployment descriptor file to webservices.xml. please let me know a solution.

I believe this is a bug in JDev/OC4J 9.0.3 that is being further investigated right now. I have duplicated your problem in a simpler test case and folks are looking into it.
Mike.

Classic Web services challenge; help please

Hi :
We are developing a webservices application and our architecture is somehow falls
into different category. We have some challenges in creating stateful web services.
First and foremost, our webservices is going to be within corporate and the direct
user of the service @least initially is some other web-based application (GUI), which
may inturn be accessed by users.
Challenge:
We may need to maintain a state for every users. The web based HTTP session wont'
work as the users are routed thro' another interfacing application. So for our web
service the request comes from single IP.
I think we should write our own session management layer for maintaining user session.
Just wanted to know is there any standardized way of doing this ? does weblogic
provide some feature or doc.?
we will be able to identify every new user in web service with the help of calling
application. so identifying new user is not a problem.. its all about maintianing
session.
any help, all suggestions welcome and appreciated ,
Venki

Thanks manoj and bruce:
manoj, the challenge of session management is solved if we were to use stateful
session bean. Whereas our implementation i'm not sure we can use stateful session
bean. Our arch. is doesn't require stateful part( which i can always explain if
need), so introducing stateful session may be the only req. to maintain user session.
But the real problem is our application individual users cannot be identified
as our arch..
calls WS
User ---> GUI APP ------------> WS
So the User is unaware of WS and user request will not be directly forwarded to
WS. So we may need to maintain our own session.
Introducing conversation ID can solve identification challenge, whereas i'm concerned
on maintaining session per sever.( like storing [converstaionID,SessionInfo] map).
using Custom maps work well in single mode whereas in clustered environment ,
the map should be supported for seamless migration of session in fail over.
Option:
Using single HTTP session per server and storing conversation map , is good but
the size is huge and memory replication traffic will be enormous as every request
modify the data.
I feel this is one of the major challenge, whereas minor ones' are manageable.
My primary concern is on scalability and reliability.
Hope this helps, ( if needed i'll be able to detail down further,lemme know mailto:[email protected]

An example of using state full session bean is attached.
In this example the web service component does the
state management. It needs to do lot of work to achieve
this, but it gives better control on how the sessions
are maintained. For eg: where to put the session info
(which header/body part), when to start/end a session etc.
If there is lot of interest in this kind of use case, it is not
that difficult to roll this example out as a web service end
component. Let us know.

Jdeveloper web services

Does Jdeveloper use AXIS as the web services pack OR Jdeveloper has its own jar files ?
Thanks

AFAIK I think it uses its own implementation.

Need JDeveloper Web Service with HTTP POST method

Hello all,
I am creating a Web Service from a java class using JDeveloper. The wsdl created uses a SOAP binding. When I test the web service, either through JDeveloper or by deploying to OAS, the HTTP request created uses the HTTP GET protocol. I am assuming that this would be the same for anybody doing this.
I need to know how to change it to be an HTTP POST protocol instead.
The reason that I need to try and use the POST method is that the xml needed by the service holds a lot of data and the http server is giving me a "URI too long" error. I have read and been told that using POST instead of GET would help this, but I can't figure out what to change to make this happen. I am not sure if I have to make a change in the generated wsdl or somewhere else. Or if it just won't work that way.
Any help you can provide would be appreciated.
Thanks,
rob

Jdeveloper Web Services Documentation

hi , i'm developing web services using jdeveloper 10g , these web services are an application modules web services , i'm writting a full java documentation for the methods in my application modules classes , when i generate the web service , the methods "service" documentation is not included in the generated wsdl file ,
how i can show this documentation in the wsdl file , to make it easier for those whose viewing the web page for that service to see a clead description of the service ????

Hi,
any news on this since last year? Or any other solutions to do it automatically?
It would be essential to have the WSDL documented by automatic generation from javadoc or even from PL/SQL comments when using PL/SQL web services.
At least / besides, a tool/dialog in JDeveloper would be nice which substitutes manually inserting a lot of documentation tags.
Regards,
Patrik

The same webservice, with stubs created using Axis2 ADB works...

The problem was in the web service, not in the proxy.
The web service did not set the "nillable" attribute of one of its inputs, so the client had exceptions. Setting to "true" or "false" the attribute, fixed the problem on client.

Type mismatch on SOAP Web Service method invocation

When I run the generated client for a web service, I get the following error, which I can get rid of by using a primitive type (e.g. String) as the parameter to doSomething instead of wstest.test2.APIClass3, i.e. the SOAP server seems happy handling wstest.test2.APIClass1 as a return type, but not a similar class as a parameter type:
[SOAPException: faultCode=SOAP-ENV:Server; msg=type mismatch [java.lang.IllegalArgumentException]]
     wstest.test2.APIClass1 wstest.test2.EmbeddedStatelessTest2Stub.doSomething(wstest.test2.APIClass3)
          EmbeddedStatelessTest2Stub.java:89
     void wstest.test2.EmbeddedStatelessTest2Stub.main(java.lang.String[])
          EmbeddedStatelessTest2Stub.java:48
I am using JDeveloper9i 9.0.3 Preview and the standalone OC4J 9.0.3 that came with it. I followed the Oracle9i JDeveloper 9.0.3 Web Services Quickstart Install (http://otn.oracle.com/tech/webservices/htdocs/quickstart/quickstart903.html) to get OC4J running standalone. I had to register the stateless EJB provider, and the WEB services wizard didn't manage to include APIClass2 (an instance of which is contained in APIClass1) in the .dd so I added it manually which works fine with APIClass1 as the method return type.
Sorry for the length of this posting, but I wasn't sure which bits would be relevant.

I believe this is a bug in JDev/OC4J 9.0.3 that is being further investigated right now. I have duplicated your problem in a simpler test case and folks are looking into it.

Appreciate any help. Thanks.

Ok, this sounds like a known bug ( Bug 5908689 ) in 10.1.3.1, but this was specific to non-Windows platforms. Are you on Linux/Solaris or any other platform? It might or might not be the same problem you are hitting but it does seem quite close (can't say for sure without a close investigation, I am afraid!)
In any case, this bug is fixed in the 10.1.3.4 patchset (besides quite a few other fixes and enhancements) - so would recommend you to first apply the 10.1.3.4 patchset and retest. The patchset is available on My Oracle Support (formerly Metalink) under Patch 7272722. Or you could go a step ahead, and apply the 10.1.3.5 patchset (Patch 8626084) instead which is the latest patchset for OracleAS 10.1.3.x.

Web Service Error - No Result Tree to Report On

After successfully creating a web service reference and then using the 'Form and Report on Web Service' wizard I get an error, after defining the input items, at the 'Web Service results' Stage.
It states :
"No Result Tree to Report On
This Web service does not have a result tree in its definition that is appropriate for a report. You may wish to run the Form on Web Service wizard instead."
This web service returns an array of records and runs successfully outside of HTML_DB. Has anyone else had this problem ? I cannot find any information about this so far. I am using App Ex v2, 10g App Server and 9i (9.2.0.4.0) DB. The WSDL file for the web service is below.
Thanks

This has been the subject of bug 5394491 for several weeks now without any resolution. It looks like this error will prevent the use of Jdeveloper web services that use array parameters in the current versions of Application Express. We are not planning to use Application Express for this purpose any more as there is no information about the bug (or fix) forthcoming.
