This post covers issue encountered during EBS R12 integration<\/strong> with Oracle\u00a0WebCenter<\/strong>.<\/p>\n

Oracle EBS R12 integration with Oracle Webcenter Suite is explained in My Oracle Support Note # 1074345.1 <\/strong><\/p>\n

For EBS-WebCenter integration :<\/p>\n

1.<\/strong> You must first register WebCenter server in list of allowed servers to access EBS OA_HTML\/portlets\/*******.<\/p>\n

This is done by adding webcenter server name in s_trusted_portal<\/strong> in Context File<\/a>\u00a0and run AutoConfig <\/strong>here<\/a> and here<\/a><\/p>\n

Note<\/strong>: Running autoconfig adds server name in apps.conf <\/strong>under $INST_TOP\/ora\/10.1.3\/Apache\/Apache\/conf\/apps.conf \u00a0(For R12)<\/p>\n

2.<\/strong> You must then register EBS Suite Portlet Producer<\/strong> with Oracle WebCenter so that EBS Portlets can be displayed to WebCenter page .<\/p>\n

EBS Portlet Producer can be registered with WebCenter either using WebLogic Scripting Tool <\/strong>– WLST : registerWSRPProducer <\/strong>or using FMW Control \/em of webcenter (GUI).<\/p>\n

If you register Portlet Producer in webcenter and hit error like<\/p>\n

____<\/p>\n

Error occurred while performing mbs.queryNames(objname) for “oracle.webcenter.portlet:name=ProducerManager” None<\/font><\/p>\n

Error retrieving WSDL at URL “http:\/\/innowave12.com:80\/OA_HTML\/portlets\/WSRPBaseService?WSDL”
\n____<\/font><\/p>\n

Then check following things<\/p>\n

a)<\/strong> Check if WebCenter server can telnet to EBS on port 80 (web port) – If not then check if EBS Middle Tier is up and EBS Apache port is open (80 in this case) between WebCenter and EBS<\/p>\n

b)<\/strong> Check if you can access URL http:\/\/innowave12.com:80\/OA_HTML\/ portlets\/WSRPBaseService?WSDL<\/strong> from webcenter machine . Use tool like wget<\/strong> on Unix<\/p>\n

c) <\/strong>If from wget you get error code 500 , then check EBS Suite OC4J logs (Oracle Container 4 Java). For log location in EBS R12, click\u00a0here<\/a><\/p>\n

In my case error message was 403 – Access Denied<\/strong>\u00a0which means EBS Suite has denied access to WebCenter Server for URI \/OA_HTML\/portlets\/WSRPBaseService?WSDL<\/p>\n

Output from wget http:\/\/innowave12.com:8000\/ OA_HTML\/portlets\/ WSRPBaseService?WSDL<\/strong> \u00a0(from webcenter node)<\/p>\n

___<\/p>\n

Connecting to<\/font><\/p>\n

> innowave12.com[192.168.1.12]:8000\u2026 connected.
\n> HTTP request sent, awaiting response… 403 Forbidden
\n> 16:51:49 ERROR 403: Forbidden.
\n<\/font>___<\/p>\n

This message means that WebCenter server can connect to EBS Suite server but access to URI OA_HTML\/portlets\/WSRPBaseService?WSDL is denied<\/strong> by server (ERROR 403: Forbidden<\/font>)<\/p>\n

If you check EBS Apache Server access_log <\/strong>& error_log<\/strong> (for log location in EBS R12 click here<\/a> )<\/p>\n

_______
\n[Mon Jan 30 11:10:20 2012] [error] [client 10.10.1.24<\/strong>] [ecid:1327921819: 172.22.81.141 :6094906:0:1167,0] client denied by server configuration: \/OA_HTML\/portlets\/WSRPBaseService
\n_______<\/font><\/p>\n

Where \u00a0IP address of WebCenter machine is 192.168.1.15 \u00a0(10.10.1.24 is one of IP from NAT pool load balancer and request to EBS goes via load balancer)<\/p>\n

Access to URI is controlled by configuration file<\/p>\n

$INST_TOP\/ora\/10.1.3\/Apache\/Apache\/conf\/apps.conf<\/strong> with entry like<\/p>\n

Default Entry
\n<Location ~ \/OA_HTML\/(portlets|providers)\/*>
\nOrder deny,allow
\nDeny from all
\nAllow from localhost
\n<\/Location><\/font><\/p>\n

Above setting allows access to portlet URL only from localhost address of EBS Middle Tier<\/p>\n

After adding Webcenter Server hostname\/IP in context file (s_trusted_portal) you should see entry like<\/p>\n

<Location ~ \/OA_HTML\/(portlets|providers)\/*>
\nOrder deny,allow
\nDeny from all
\nAllow from localhost webcenterhost 192.168.1.15
\n<\/Location><\/font><\/p>\n

Above configuration means on \/OA_HTML\/(portlets|providers)\/* , access is allowed only from localhost, webcenterhost and 192.168.1.15.<\/p>\n

Issue: <\/strong>In my case request from WebCenter host to EBS goes via Load Balancer and though request to portlet originates from WebCenter Host, for EBS client is Load Balancer NAT address.<\/p>\n

Fix:<\/strong> Add load balancer NAT address in\u00a0s_trusted_portal <\/strong>in context file and run Auto Config.<\/p>\n
