I'm just guessing but you run your code and get the
ORA-30625: method dispatch on NULL SELF argument is disallowedand then after a while you eventually start getting
ORA-29270: too many open HTTP requestsIf so, ORA-29270 happens because I don't see your code closing the HTTP connection when an error happens. In other words, does your error handling close the connection as well?
The ORA-30625 is happening because your are calling an XMLType based function and passing in a NULL value. This usually happens (to me) when I nest XMLType functions and one returns NULL due to an error. I have no clue what your line 9 is so I can't guess what you are doing to get the error though.
I m assuming the following code closes all the connections
I m calling the procedure from sql plus like this
UTL_HTTP.END_REQUEST (http_req); UTL_HTTP.END_RESPONSE (HTTP_RESP);
Is there a parameter for no. of http connections to be made from PL/SQL, any kind of setting, I assume the webservice is not returning any response bcos of too many http requests and therefore its failing

Can someone please let me know how to go about?
In my SOAP RESPOND variable I get server failure error, So i think its not connecting to the webservice, which is on my pc,
I dont know what to do next, it was working fine 2 days back, and I can access the web url from browser and it works fine, So something in pl/sql which is not allowing me to connect now.....
When i debug line by line, i get an error in the Insert into staging XMLTYPE(SOAP_RESPOND) bcos SOAP_RESPOND contains Server Failure Error.
utl_http.set_proxy (proxy => 'http://confirm:email@example.com:8080'); http_req :=utl_http.begin_request ('"http://hullcc-37692/WebApi/WebService1.asmx"','POST','HTTP/1.1'); utl_http.set_header (http_req, 'Content-Type', 'text/xml'); utl_http.set_detailed_excp_support(true); utl_http.set_authentication (http_req, 'confirm', 'c0nf1rm'); utl_http.set_header (http_req, 'Content-Length', length (soap_request)); utl_http.set_header (http_req,'SOAPAction','"http://webapi/Streets_Events_Get"'); utl_http.write_text (http_req, soap_request); insert into xxhcc_staging_xml values ((xmltype (soap_request)), sysdate,'Street_Events_Get SOAP Request'); commit; http_resp := utl_http.get_response (http_req); utl_http.read_text (http_resp, soap_respond); insert into xxhcc_staging_xml values ((xmltype (soap_respond)), sysdate,'ssssss'); commit; --RESP := XMLTYPE.CREATEXML (SOAP_RESPOND); utl_http.end_request(http_req); utl_http.end_response (http_resp); --RESP := XMLTYPE.CREATEXML (SOAP_RESPOND);
Not sure why its not conecting to the URL which is my pc only.
I m stuck here, Any inputs appreciated?
All you should need is
Here is the documentation on the difference. Since you are completing a normal process and not aborting after you send the request, that is all you need.
ERROR at line 1:This is because xml_out variable is null as you appear to have discovered in your later posts.

Is there a parameter for no. of http connections to be made from PL/SQL, any kind of setting, I assume the webservice is not returning any response bcos of too many http requests and therefore its failingThe issue is not because of the remote web server but because of your code failing to close the connection. Without seeing the full path of your code, I cannot determine why it appears to not be executing the END_RESPONSE line above. I still suspect it is throwing an error you are hiding in your code.
when i give the ip address of my machine it works but when i give the actual name of my pc it doesnt workDoes your host file resolve the name of your machine to the current IP address? I doubt your companies DNS does but I could be wrong. The easiest fix is to add an entry to the host file on your OS to resolve that issue.
Never used that package before but it appears it should, as long as something somewhere supports resolving the name into an IP address. You also need to consider the machine this code will be deployed to. Will it already be able to resolve the name to an IP address when UTL_HTTP is used? Servers usually are configured to be able to do that since I suspect the web service will not reside on the server. This is where you need to change your dev environment to function like the Test/Prod environment will and not code in fixes that work on your dev machine but add overhead to the Test/Prod environments.
* All the above is based on past experiences and it could be your networks are setup differently and all I said is wrong.
Yeah I know what u r saying, i will test if the method works fine in the DEV and LIVE environments, We have like TEST,DEV and LIVE setups, and I m sure if it has worked on one of the environment it shuld work in others too.
As of now the webservice is hosted on my pc, We wuld be moving that to a server and i hope all servers shuld be able to communicate with each other.
