Consumption of web services in J2EE app

Hi experts!
I have an J2EE java application, and I need to consume some external web service there with configuration capabilities in NWA->Application Communication->Consumed Services (like as using Enterprise Web Service model WebDynproJ app).
Now I'm using JAX-WS for this purpose, but the problem is there are no possibility to configure its endpoint and call parameters via NWA console.
Is there some way to do it?

Certificate Issue in web services Using j2ee in oracle apps 11i

Hi all,
I am working with web services integration in oracle apps 11i. I used j2ee technology. I installed j2eesdk-1_4_03 and test with j2eetutorial. I have to integrate third party payment system with web services in oracle apps 11i. I run following commands in putty
build: asant build
packing: asant create-war
deploy: asant deploy-war
client java:
compile: asant build
run: asant run
While i run the "asant run" command, i got below the error
sun.security.validator.ValidatorException: No trusted certificate found
I added third party certification but i got same error which i mentioned above.
Is any certification or settings need for run the web services in ebs.
Thanks

Hi,
I do the settings according to your advice, i got below error when i run below command to add certificate to keystore.
command:
keytool -import -keystore /usr/j2ee/jdk/jre/lib/security/cacerts -file /usr/Class3G2.cer
Error:
keytool error: java.lang.Exception: Input not an X.509 certificate

Learning Web Services with J2EE

Hi:
I've been developing in J2EE for 3 years now, using Servlets/JSP/Tag Libraries etc.... I want to find a good source (book) that teaches you web services with J2EE, does anyone recommend any good starters to advance books for Web Services.
Thank you
Goce

Have you looked at the J2EE 1.4 Tutorial?
http://java.sun.com/j2ee/1.4/docs/tutorial/doc/index.html
It includes chapters on developing both Web applications and enteprise beans as Web service endpoints.

Web services (eprint and Apps) could not be enabled

just opened my new HP officejet pro 8600 and trying to enable web service and I received the following error: web services (eprint and Apps) could not be enabled. I have no idea how to debug this issue.
Any help out there?

They are the same, however be advised that anything that is pending in the queue will be gone, as well as your current custom email address. You will have to readd the printer with a new info page, and use a different custom email address.

Web Service Client(Console App) not working on Windows Server 2008 R2 Standard Edition

I am trying to consume an ASMX Web Service in a console app, its working fine in Windows 7,Windows Server 2012 Standard,Windows Server 2008 R2 DataCenter,Windows Server 2008 R2 Enterprise, But its not working in Windows Server 2008 R2 Standard Edition which
is the deployment server.
I tried consuming the ASMX web service using Web Reference and Service Reference as well but its not helping. Its throwing up the following error,
Message:There is an error in XML document (1, 331491).
Inner Exception : System.Xml.XmlException: '.', hexadecimal value 0x00, is an invalid character. Line 1, position 331491.
The scenario is that i call the web service and it returns me an XML i am not able to receive the XML on Windows Server 2008 R2 Standard Edition.
Please provide suggestions on this I need to resolve this ASAP.

Hi,

Calling a Web Service from J2EE application running on WebSphere

This may have been answered before, but could not find using multiple searches that I did on this forum.
We are just in the process of using the newly installed SAP WAS 6.40 with J2EE engine and I understand from SAP's documentation that all BAPIs and remotely callable RFCs should be invokable via a Web Service call from remote applications. Couple of questions on this:
1. Is there a documentaion that describes steps to enable BAPIs or RFCs as web services?
2. Is there a documentation that describes steps to invoke a web service that in turn uses BAPI or RFC (code sample).
We are J2EE literates but not familiar with SAP WAS, and not sure if calling/invoking the WS would be similar to calling any other WS from other WS Containers.
Appreciate a response or suggestions.

Hi Bharat,
see this weblog , where it gives the steps to create a RFC and convert it into web service.
/people/thomas.jung3/blog/2005/01/05/develop-a-web-service-that-sends-an-email--in-abap
Invoking WS is similar to calling any other WS from other containers. Either you have to give the WSDL file location or the external UDDI Server address in WebService creation wizard.

How to configure CA for access to a Web Service from an app deployed in WL

Hi everyone.
I have an app deployed in a WLS (10.3). This app acts like a web service client and works correctly (spring + cxf). The web service is provided by an external company and now they want to switch to https. They are using a self signed certificate. My company's support staff told me that they already configured the domain's trusted key store but the app fails to invoke the WS with the following error:

I'm the app's developer and I don't have experience in this subjects. Is the wl misconfigured? Should I do something from the app to reference the keystore?
Thanks un advance.
Sorry for my english.

Hi user10939158, thank you for your response. Maybe I was not precise in my previous post. I know how certificates work and that I should not be using self signed ones. Due to a reason (non technical) we MUST use a self signed certificates. Considering this as a prerequisite let me clarify my situation:
- We added the certificate to the custom trust store connfigured in WL
- We configure the managed server to be more "verbose" about SSL stuff
- When the managed server start it outputs the following lines in the log:
<Dec 13, 2010 5:31:21 PM ARST> <Notice> <Security> <BEA-090169> <Loading trusted certificates from the JKS keystore file /wldomains/desa_domain/TrustCTWebservices.jks.>
<Dec 13, 2010 5:31:21 PM ARST> <Debug> <SecuritySSL> <BEA-000000> <SSLContextManager: loaded 1 trusted CAs from /wldomains/desa_domain/TrustCTWebservices.jks>
<Dec 13, 2010 5:31:21 PM ARST> <Debug> <SecuritySSL> <BEA-000000> <Subject: CN=jserver, OU=SWG, O=IBM, C=US; Issuer: CN=jserver, OU=SWG, O=IBM, C=US>
- In this lines we can see the certificate that interests us (jserver)
- When the app do a WS reqeust we see in the log:
<Dec 13, 2010 5:32:43 PM ARST> <Notice> <Stdout> <BEA-000000> <trustStore is: /opt/bea/jrockit_160_05/jre/lib/security/cacerts> (THE VM's DEFAULT KEYSTORE!!!!!!)
- If we add the cert to /opt/bea/jrockit_160_05/jre/lib/security/cacerts everything works ok but I have doubts that this is right.
Why the default keystore is used?
Thank you very much

Consuming RESTful web service in Apex app

Hi,
I have created a RESTful Web service through an Apex application (4.0) and published as a public web service. Can someone point me to an example of how to then consume that service in another Apex app? The output is straightforward XML that I can retrieve just by pointing the browser to the URL of the service created, but when I go to create the REST Web Reference for the receiving application, I am not sure what to put for the Response Xpath or Response Namespace. The service is meant to just return report records that were created in the REStful Web service with no input required.
The service XML looks like this:
<ROWSET>
<ROW>
<PROJ_ID>132</PROJ_ID>
<PSL_NETID>xxxxxxxx</PSL_NETID>
<PROJECT_TITLE>11g- Oracle Upgrade to RAC 11g</PROJECT_TITLE>
<CUSTOMER>OIT</CUSTOMER>
<DIVISION>EIS</DIVISION>
</ROW>
<ROW>
<PROJ_ID>132</PROJ_ID>
<PSL_NETID>xxxxxx</PSL_NETID>
<PROJECT_TITLE>11g- Oracle Upgrade to RAC 11g</PROJECT_TITLE>
<CUSTOMER>OIT</CUSTOMER>
<DIVISION>CSS</DIVISION>
Any help would be appreciated.
Thanks,
Pat

Hi,
I have made progress in this. I created the RESTful report service in an Apex 4.1 application. (previous attempt was with 4.0 version of Apex)
I then created a separate application and created a RESTful web service reference that I tested and it was successful in bringing up XML. However in Apex 4.1, when I create a report following the Wizard for creating a report based on that Web service reference I get the error: ORA-31013: Invalid XPATH expression Which I don't know how to get past. The Xpath provided in the Web service reference test gave output below and brought back a result. There was no where during the Report creation to provide an Xpath. Am I missing something or is 4.1 not quite Web service ready??
This is what I get from the test of the Web service reference in the Apex App from which I want to create a report: (I see in this XML the data I was expecting from the test of the RESTful web service but it looks like the output I get from the Web service test is more like the Report xml itself.)

How to use web services in JSF app

I am unsure if this is the right forum for this question. Let me know if it is not - and where I should go.
Anyways, I'm building a JSF web app, in which there is a datatable page displaying some business data. The app is going to be deployed and run in the customer's web server, but the data to be displayed is from the business solution provider's database. Currently the provider supplies web services to retrieve the data. So, my task is to call these web services from my JSF page, get and display the data.
I've never used web services before. Can someone give me a quick start, as what I need to know to use these web services, and how to use them in coding terms. I googled the web quite a bit and finally decided to turn to SDN forum.
Thanks!

Web Services with Sun App Server

We are load testing a simple web service running in SJSAS 8.0 Standard. With 1 or 2 users concurrent it seems OK, but once we move up to 5 concurrent users calling the WS, the domain in SJSAS crashes.
Does anyone have experience or information regarding the app server and load with web services? Are there some config options that we can tweak? Are there any numbers out there about how many simultaneous connections the server can handle?
A final note, things seem fine if we are just serving a simple web page from the server, its only when we try to call a WS that we run into these performance issues.
Thanks.

Are you connecting to any external resource using JNDI by any chance? If you're using Unix, check the number of file descriptors being opened on the Sun App server. "new dirContext(env)" creates OS file descriptors each time it's invoked (calling the web service for example).
use
$ps -ax
get the process number of sjas and try issuing a:
lsof -p <sjas_process_number> |wc -l
and keep invoking the web service. If this number keeps increasing then you've an "fd" leak (perhaps not closing the dirContext). Linux for example has a default max file limit of 1024 under "root" user and when depleted, sjas will hang.
Could this be the problem?

Oracle Web services and J2EE 1.4

Hi,
Can anyone tell me if the Oracle Web services generated by Jdeveloper from a Java Class is compliant to the specification: Web services J2EE1.4 (JSR 109) ?
Thanks,
Best Regards,

In JDeveloper 10.1.3 the J2EE 1.4 (JAX/RPC) Web Services are.

No web services show under web services node in app server navigator

Hi,
(JDev 11.1.1.5.0 and WLS 10.3.3.0)
In JDeveloper Help, the topic Publishing Web Services to a UDDI Registry says:
1. Deploy the web service to Oracle WebLogic Server.
2. In Application Server navigator, expand the application server node.
3. Expand the web services node and locate the node (which represents the WSDL) of the web service you want to publish.
4. Right-click the WSDL node and choose Publish WSDL to UDDI to launch the Publish WSDL to UDDI Registry dialog.
I did 1, 2 & 3 but nothing shows under the web services node in the app server navigator.
There are lots of web services in that server, not only the one I had just deployed.
What can be wrong?
Thanks
Luis

Hi SilverCat,
I'm sorry to hear that you are having problems getting your claim code to setup ePrint on your Officejet 6700.
Yes you can obtain the printer claim code. There are a couple different ways that you can do so. The steps to do so can be found in your user's guide starting on page 69. I have included a link to your User Guide. The easiest is to do it from the front panel of the printer. I have included a document on getting your printer claim code and it has those steps for you. I have also included a document on getting started with HP's ePrint for additional reference.

Java Web Service Deployed on App server does not run

hi,
I created a java web service and deployed it on my Application server. When i open the enterprise manager i find my webservice there. I click on test web service and it gives me two options one with a 4443 port and other with a 7777 port. It picks up a 0.0.0.0 hostname though i deplyoed it on to a different machine.
I choose to use the 7777 port and test the web service whrn i click invoke it give me the error
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
and when using the 4443 port it gives me the error as
"SSL Error: unable to find valid certification path to requested target"
please suggest how i can test a simple java webservice.
Thanks
Sravanti

I think the problem is to add the custom dll files while deploying the application. Could any one please suggest how i can add custom dll file for deployment?
Thanks

Securing a 1.5 web service using J2EE security and JDev 11g

Hello,
I'm looking for a tutorial or similar that will help me create a secure (1.5 EE with annotations) web service. I'm interested in just the development view at this point - xml file mods, etc.
I did find a good resource on how to do this in 10.1:
http://www.oracle.com/technology/products/jdev/101/howtos/securews/index.html
and am wondering if it has been updated (even beta!) or in another form.
Thanks

Steve,
The WSDLBaseURL property just prepends a string to the WSDL URL property so that you can abstract out the protocol, server and port values separately depending on the target system you wish to hit for the service call.

Web service in j2ee

Hi Guys,
I create a java application for connecting to sap using sap-connector. and expose that java application as a webservice. Its perfectly working. Now i have to call the web service in a web application. Means i have to call the webservice in a jsp. But i am unable to do this. But in a normal java application i am calling the web service.
Thanks,
Kharthik

What version of AS Java are you using? The technique depends on that.
For Java EE 5 (NW CE 7.1) --> [Creating Web Service Client Applications|http://help.sap.com/saphelp_nwce10/helpdata/en/45/113a1221337249e10000000a155369/frameset.htm]
