I have down loaded WSO2 ESB Version 4.6 and started the server. Clicked on proxy service. There I have selected WSDL Proxy option. It is asking the following for creating proxy.
Proxy Service Name* OpportunityService
WSDL URI* https://crm-aufsn4x0ruf.oracleoutsourcing.com//opptyMgmtOpportunities/OpportunityService?WSDL
WSDL Service* https://crm-aufsn4x0ruf.oracleoutsourcing.com:443/opptyMgmtOpportunities/OpportunityService
WSDL Port* 443
I just want consume this external web service via ESB. So I dont want publish. Did not configure any publish related fields. Now When I click on create it throws exception "Failed to add proxy service: OpportunityService. Check whether the Proxy already exists
". But I am sure that there is no existed service with that. I have tried with different names but the error is same.
I suspect that may gave values wrong for fields WSDL Service and WSDL Port. If click on Test URI its giving success.Can any one please suggest where I am doing wrong.
Thanks&Regards,
Raghu
For wsdl service parameter you need to give the <wsdl:service name>which you can find in the particular wsdl itself. I dont think it will be a URI like you have mentioned above. Likewise for port you can find the <wsdl:port> parameter in the wsdl.

We have deployed our webservice in liberty server.Earlier it was on IBM WAS. After deploying in liberty, we came to know that Webservices is running on CXF webservice framework. In WAS, it was Axis framework.
Another difference is that , changes happened in wsdl url & content. The old wsdl url is http://localhost:8080/Hello/HelloServices/Helloservices.wsdl and it contains xsd schema definition.
In the liberty server above wsdl url is not working and throwing file not found. But if we try to invoke http://localhost:8080/Hello/HelloServices?wsdl it's working.
Could anyone tell why old url is not working in New server. Is it due to server or inbuilt cxf framework in server.
Another team is using wsdl url to consume this webservice, with this new url they are not able to achieve it.
Any thoughts or suggestions are appreciated..
Thanks in Advance
The main reason for this is the change in the JAX-WS implementations used by the different WebSphere profiles. CXF, unfortunately, hard codes the WSDL url to append ?wsdl in several locations and so this is something that is not possible to change in configuration. The easiest solution would to add a ServletFilter to check the incoming request url for http://localhost:8080/Hello/HelloServices/Helloservices.wsdl and then redirect the request to http://localhost:8080/Hello/HelloServices/Helloservices?wsdl.
There's a good SO post that shows how to write a ServletFilter to redirect here:
How to use a servlet filter in Java to change an incoming servlet request url?
The other option would be to have the client side update either their code or configuration to account for the change to the WSDL URL.
I am new in the area of SOAP Based web services. I am using TomEE server. The server is a bit customized according to my organization's need.
Few days back, when I was trying to run the web services example from TomEE website, I was able to generate the wsdl and calling the web service by a client.
Now, when I need to use the customized version of TomEE plus (by the organization), I can see that the request does reach to the server and hence there is a log entry also but my #WebMethod is not getting executed.
Does any one has any idea about any configuration which can prevent the request from reaching to the webservice method? Is there any pointer around how can I debug further to reach out to the root cause of this issue?
Without further information about what is customized it's like fishing in the dark.
I would guess that perhaps the global web.xml or the server.xml of tomee server is changed so that some URI context mappings are not forwarded or ignored. But it's only a lucky tip.
I try to use WSO2 ESB at workplace where Proxy Server is available.
Set Proxy Server settings in axis2.xml,
Install certificate.
Initialize Salesforce connector(Salesforce certificate has been installed).
Test the API, run into an exception - SOAPProcessingException,
Really appreciate if someone can give ideas of solution.
First of all I have tried this type of a scenario using WSO2 ESB 4.9.0 and which was perfectly working fine. By looking at your error messages I can see that there was an Authentication failure, hence Sales Force end point returns some HTML error message. The ESB tries to build this HTML error message using the SOAP builder leading to this situation.
This could be due to some missing configuration in your setting. You may follow [1] to enable HTTP Proxy to Sales Force. Then to setup Sales Force [2] will be helpful.
Couple of thing I need to highlight here. Did you import the Salesforce certificate into the ESBs client trust store using the keytool import command. If not please go ahead and do so. Also is there a particular reason for you to use NHTTP transport here. Ideally we would use Passthrough transport to add the proxy host as given in [1].
If you still get the error after following the above steps please enable the wirelogs and post it here to investigate further. Follow these steps to enable wirelogs.
Open log4j.properties file from a text editor.
log4j.properties file is located in $ESB_HOME/repository/conf directory.
Un-comment the following entry.
log4j.logger.org.apache.synapse.transport.http.wire=DEBUG

I am trying to create a proxy in ESB using the wsdl. The log says: "Unable to add proxy service: Failed to add proxy service: HCCProxyService. Check whether the Proxy already exists-Failed to add proxy service: HCCProxyService. Check whether the Proxy already exists" but existing proxy service is not their in application server,
and other issues is that its always redirect logine page after some moment of time both wso2esb and wso2as application server also.
I don't know what to do. What is the configuration for my scenario? Please help me!
It seems you are adding already existing proxy. Yo can go to ESB_HOME/repository/deployment/server/synapse-config/default/proxy-service folder and check for the your_proxy_name.xml file and delete it.
Then you may recreate it with the UI. Other issue is due to session timeout. You may ask browser to remember your credentials.
I have done a few use cases on WSO2-ESB including protocol mediation with transformation and service-chaining.
In all of them I had to manually write the wsdl for the proxy service. Having experienced other vendor products including Oracle and Tibco where wsdl generation is done by the tool.
Would it be right to assume in WSO2 ESB one needs to manually write the wsdl file to expose a proxy service on any protocol, do not see any documents calling that out.
Considering the usage of wsdl in practical use cases.
I have seen posts stating "you can give the WSDL available at your Axis2 service" but most of real time use cases would not be pass through and have custom request and response.
Thanks,

I'm also confused with manual wsdl creation. As far as I can see there are gaps in wsdl proxy description. When I do wsdl proxy with WSO2 I have to indicate wsdl to expose
its either as:
"none" and I have only mediate function exposed
"same contract" and this breaks the whole idea of proxy because after that clients read original wsdl and go straight to original server access point.
or and I have several options to make my own wsdl.
With rich SOAP API (hundreds of methods) none of above work well, considering that manual support of exposed WSDL is rather cumbersome.
I wonder if there is more adequate way for proxying WSDL?
You can use java2wsdl generator tool to achieve the WSDL generation.
For the proxies, if you try to restrict access for some operations in your backend service, you can attach customized wsdl to the proxy.
The customization has to be done by yourself and it is simple..
If you want to generate a wsdl fro your service, jsut deploy the service in wso2as, and check the service dashboard, wsdl option to view the wsdls.
