Oracle APEX calls web service

Oracle APEX calls web service:

1)     Create web service reference in sharedcomponents and invoke.

You can follow the following demo:

Creating and Using a Manual SOAP Web Servicein Your Application

http://apex.oracle.com/pls/apex/f?p=44785:24:7736223348442:::24:P24_CONTENT_ID,P24_PREV_PAGE:5815,24

 

2)     Invoke web service API in PLSQL block: APEX_WEB_SERVICE

You can refer the doc:

http://docs.oracle.com/cd/E37097_01/doc/doc.42/e35127/apex_web_service.htm#BABFFDEH

 

APEX_WEB_SERVICE.MAKE_REQUEST(

    p_url               IN VARCHAR2,

    p_action            IN VARCHAR2 default null,

    p_version           IN VARCHAR2 default '1.1',

    p_envelope          IN CLOB,

    p_username          IN VARCHAR2 default null,

    p_password          IN VARCHAR2 default null,

    p_proxy_override    IN VARCHAR2 default null,

    p_transfer_timeout  IN NUMBER  default 180,

    p_wallet_path       IN VARCHAR2 default null,

    p_wallet_pwd        IN VARCHAR2 default null )

RETURN XMLTYPE;

 

Table 22-4 MAKE_REQUEST Function Parameters

Parameter	Description
p_url	The URL endpoint of the Web service.
p_action	The SOAP Action corresponding to the operation to be invoked.
p_version	The SOAP version, 1.1 or 1.2. The default is 1.1.
p_envelope	The SOAP envelope to post to the service.
p_username	The username if basic authentication is required for this service.
p_password	The password if basic authentication is required for this service
p_proxy_override	The proxy to use for the request. The proxy supplied overrides the proxy defined in the application attributes.
p_transfer_timeout	The amount of time in seconds to wait for a response.
p_wallet_path	The file system path to a wallet if the URL endpoint is https. For example, file:/usr/home/oracle/WALLETS. The wallet path provided overrides the wallet defined in the instance settings.
p_wallet_pwd	The password to access the wallet.

 

·        p_wallet_path to a wallet if the URL endpoint ishttps.

For windows: file:c\oracle\wallets

For linux : file:/usr/home/oracle/wallets

For Oracle Cloud: you don’t need to configthe wallets, since Oracle Cloud already has a lot of certification.

 

Eg. https://xxx:443/opptyMgmtOpportunities/OpportunityService?WSDL

You need to export the root/parentcertificate.

Refer (http://blog.whitehorses.nl/2010/05/27/access-to-https-via-utl_http-using-the-orapki-wallet-command/)

·        p_username/p_password is needed for https site.

 

Here is the PLSQL procedure to invoke the web service:

You need to add the WSSE:security policy in the HTTP headerfor username-token security policy web service
