Running PL/SQL Web Service Example

Hi,
I followed all the steps as mentioned in the example "Publish PL/SQL as a Web Service" but I am getting the following error:
[SOAPException: faultCode=SOAP-ENV:Server; msg=[SOAPException: faultCode=SOAP-ENV:Server; msg=]]
     scott.Employee mypackage1.CompanyStub.getemp(java.math.BigDecimal)
          CompanyStub.java:111
     void mypackage1.CompanyStub.main(java.lang.String[])
          CompanyStub.java:68
Process exited with exit code 0.
Can anyone please help me resolve this error?
Thanks in advance,
Jatinder

Well the good news is that you got the row added so the SOAP messaging is at least working. It seems odd that you can add
the employee and not have the same error ... the add process should run into difficulties with the same class presumably that you
are having with the getemp one.
I am grasping at straws here ... are you using a JDK that is JDK 1.3.1_02 or higher? I know OC4J has some problems with 1.3.1_01.
I see you are on Solaris ... is that JDev or just the app server? DB version shouldn't matter if your install worked fine.
Perhaps the last thing you could post is the full log of the error message you see in JDev that might have some clues too. If you are
running JDev on Windows, if you start it up with jdev.exe instead of jdevw.exe it will also put up an internal logging DOS window that
may have some other pointers.
That's about all I can think of.
Mike.

Problems deploying PL/SQL Web Service example to standalone OC4J

I have built the PL/SQL Web Service example EMP_FETCHER in the tutorials that come with JDeveloper. When run with the embedded OC4J container, the web service works ok using the autogenerated client. However, while I can then successfully deploy the web service to a standalone OC4j instance running on a separate database server, when I point the client at it, a NoSuchMethodError exception is thrown by oc4j with the following stacktrace;
at tutorial_jdbc_connection.Emp_fetcher.get_emp(Emp_fetcher.sqlj:43)

Looks like I'm missing some support libraries but I'm unsure which ones they are, and why they wouldn't be part of a standard OC4J installation.
I've tried including the SQLJ runtime and Oracle JDBC library support in the deployment and redeploying but the same error persists.
Any assistance would be appreciated

You have an old version of java installed. That is what "java.lang.UnsupportedClassVersionError" tells.

Cannot run "Publish PL/SQL as a Web Service" example

Hello!
I have Oracle 8.1.7 AS and 9i JDeveloper running on Windows 2000. I'm trying to run the "Publish PL/SQL as a Web Service" example, but am encountering errors I believe are related to my hostname/IP address/DNS entry. Of course, I could be wrong.
Here is some information:
==========================================================
1. I was able to successfully initialize Containers for J2EE. However, when I was trying to deploy the PL/SQL example, it inserted this information:
C:\oracle\jdev9i\j2ee\home>C:\oracle\jdev9i\jdk\bin\java.exe -jar C:\oracle\jdev9i\j2ee\home\oc4j.jar
Node started with id=-1753996682
Oracle9iAS (9.0.3.0.0) Containers for J2EE initialized
Error updating application PLSQL-PLSQL-WS: Error loading web-app 'WebServices' at
C:\oracle\jdev9i\j2ee\home\applications\PLSQL-PLSQL-WS\WebServices:
resource-ref 'jdbc/testCoreDS' referenced from resource-ref-mapping not found
==========================================================
2. I went through the instructions from the website, and when I began the deployment process it generated this information:
---- Deployment started. ---- Jan 17, 2003 1:20:27 PM
Wrote WAR file to C:\oracle\jdev9i\jdev\plsql-webexample\Project1\WebSe[i]Long postings are being truncated to ~1 kB at this time.

Couple of suggestions despite your post being cut off with what might be useful information (please post the rest if these suggestions don't help):
1. There are some bugs with Personal Oracle and Web services, notably Oracle9i Personal that may apply also to 8.1.7. If you have a MetaLink account it is logged as bug 2591731.
2. As you are using your local machine, make sure your proxies are turned off (Tools-Preferences Web Browser/Proxy)
3. I've noticed problems when folks use a JDK with a version lower than 1.3.1_02 to run OC4J - it is certified only with 1.3.1_02 or higher. If you are using the built-in JDeveloper JDK to start up OC4J (e.g. <Jdev_home>\jdk\bin\java.exe) you should be fine. But if you are just typing in java -jar oc4j.jar it is worth checking. Check the your default JDK version by typing in: java -version. If it is lower, then download a new version from http://java.sun.com/j2se/1.3/download.html.
4. For level setting it is best to be using build 1035 of JDeveloper, the current production release and either the OC4J embedded in it or the stand-alone version here on OTN.
Hope these point in the right direction.
Mike.

How can I return multiple values with PL/SQL Web Services

Hi,
I'm new to developping Web Services. I'm doing some tests with JDeveloper and OC4J on my local machine with a Web Services based on a PL/SQL function within a package. Right now that function only returns one value. So the xml response only has one output.
I'd like to know how can I return multiple values with my PL/SQL Web Service. For example, if I want to return an employee's name and id? And that the xml contains two output : <employee>, <empid>?
Reginald
ps : I have searched the forum and I couldn't find an answer to this question, if that has been discussed AND answered before, can you please post the link? Thanks

Alright, I actually found my answer. Since this was asked I think as a followup somewhere else I'll give my answer.
It is very simple, all you have to do is create an Object Type and then Return that object type. After that, JDeveloper will take care of everything and you will have an xml response with multiple values. Here
{color:#ff0000}
create or replace TYPE person AS OBJECT
( id_interv number,
first_name VARCHAR2(50),
last_name VARCHAR2(50),
date_birth date
);{color}
Then your function used in your Web Service should look something like this :
{color:#ff0000}
function info_emp (p_empno IN VARCHAR2) RETURN person AS
l_emp person := person(-1,'','','');
BEGIN
SELECT first_name
,last_name
,emp_no
INTO l_emp.first_name
,l_emp.last_name
,l_emp.emp_no
FROM emp
WHERE upper(emp_no) = upper (emp_no);
{color}
{color:#ff0000}
RETURN l_emp;
EXCEPTION WHEN NO_DATA_FOUND THEN
l_emp := person (-1,'n/a','n/a','n/a');
RETURN l_emp ;
END info_emp;{color}
{color:#ff0000}{color:#000000}After that, this is what the xml response looks like :{color}{color}
<first_name xsi:type="xsd:string">John</first_name>
<last_name xsi:type="xsd:string">Doe</last_name>
<emp_no xsi:type="xsd:string">0250193</emp_no>

PL/SQL Web Service: Broken Pipe

We have successfully deployed PL/SQL Web Services on the Oracle Application Server 10g with about 6 containers. The web services are being consumed by a .NET application. All seems to be working well but we continually are having intermittent (every 2-3 days) "BROKEN PIPE" errors which is causing us to bounce the container constantly. This is not very effecient for a production environment. Does anybody have any ideas........? Here is what shows up in the log:
javax.servlet.ServletException: Io exception: Broken pipe
at swprodweb.__Ws_reservationImplSPWrapper.destroy(__Ws_reservationImplSPWrapper.java:605)
at oracle.j2ee.ws.RpcWebService.destroy(RpcWebService.java:93)

at com.evermind.server.http.HttpApplication.destroyServlets(HttpApplication.java:5805)

at com.evermind.server.ApplicationServerShutdownHandler.run(ApplicationServerShutdownHandler.java:39)
at java.lang.Thread.run(Thread.java:534)
So everytime I see this error I know that we have to bounce the container. Very Frustrating!!

Hi,
Although it's a long time since you posted your message, I nowadays working with this issue, that is, calling web services from Oracle database 10g through UTL_DBWS package. It turns out that almost 3 of 100 requests fail due to this error (broken pipe). Actually, the trace is:
ERROR on line 1:
ORA-29532: Java call finished due to an unresolved exception: HTTP
transport error: javax.xml.soap.SOAPException:

Broken pipe
ORA-06512: en "SYS.UTL_DBWS", línea 403
ORA-06512: en "SYS.UTL_DBWS", línea 400
I'm looking for the cause of this error. Has anyone any idea about this?
Thanks a lot.

Oracle removed this option or really good hide it in the final version of jdeveloper 11g
But there is hope you can do it yourself with eclipselink , they have a great wiki page with all the options plus you have control how you make this ws
Here an example to make a quickstart

PL/SQL Web Service Optional Parameters

I have created a PL/SQL web service and deployed successfully using Jdeveloper 10.1.3.5. The database is 9.2.0.8.
When the web service request is made, all is well if all parameters are passed.
I have been told that the request might come with some but not necessarily all of the parameters expected by the PL/SQL procedure.
Is it possible when deploying through JDeveloper to indicate that all parameters might not be present?
This is my first web service. Thanks in advance for your assistance.

Parameters relate to procedures. Web Services require XML messages.
Where are the parameters coming from? You cannot pass a dynamic number of parameters into a procedure, but you can pass a structured type as a parameter which can contain multiple values, whether that is an array/collection type or an XML document itself.
Just package up the values into the XML and pass it to the web service.
If this doesn't answer your question, please post more information, with some example data and code. Read the FAQ: {message:id=9360002}

PL/SQL web service code in 1013 is schema-specific

When I generate a Web Service from a pl/sql package in 1013 (ea3), the code will only run against the schema that owns any user-defined SQL types that the package references. These types have synonyms on the database, but to get the code to execute against another schema I have to modify the generated type classes and add the owning schema name into the literals in several different places.
Is there a way I can get the wizards to do this for me?

Yes, we tried with databse adapter with out any problem. we want specifically with the PL/SQL Web service using the web service wizard.
Thanks in advance.

Jdeveloper 11g R2 problem when publishing PL\SQL Web Service

Hi Guys,
I have been banging my head against the wall for the past few days trying to publish pl\sql package as a web service on a weblogic 10.3 but I keep running into the same problem.
PL\SQL Package Source below
create type dept_type as object
(deptno NUMBER,
dname VARCHAR2(50),
loc varchar2(13),
cr_date date)
create type dept_list_table is table of dept_type
purge recyclebin;
create or replace package ws_package as
procedure test_dept_table (pout out dept_list_table);
end ws_package;
show errors;
create or replace package body ws_package as
procedure test_dept_table (pout out dept_list_table) is
all_depts dept_list_table := dept_list_table();
dRecType dept_type;
i number := 0;
begin
-- iterate through all depts
for r_list in (select * from dept) loop
i := i + 1;
dRecType := dept_type(null, null, null, null);
dRecType.deptno := r_list.deptno;
dRecType.dname := r_list.dname;
dRecType.loc := r_list.loc_id;
dRecType.cr_date := sysdate;
pout.extend;
pout(i) := dRecType;
end loop;
end test_dept_table;
end ws_package;
show errors;
I go and create PL\SQL Web Service using default settings in Jdeveloper 11g R2 but when I try and test this page I get the following response:
Failed to invoke end component servqa.MyWebService1User (POJO), operation=testDeptTable -> Failed to invoke method -> java.sql.SQLException: ORA-06550: line 1, column 13: PLS-00306: wrong number or types of arguments in call to 'TEST_DEPT_TABLE' ORA-06550: line 1, column 7: PL/SQL: Statement ignored
Anyone have any idea what the problem may be? Your help would be much appreceated!

Hi Frank,
I think the problem is in any procedure that has a COMPLEX TYPE as OUT parameter. So even if you strip down the procedure to just do nothing I still get the error as described in my top post. Passing complex parameters as IN parameter work fine its only when I have procedure with complex out when it errors. I also tried function that returns object parameter and that works fine too so not sure why this doesnt?
create or replace package body ws_package as
procedure test_dept_table (pout out dept_list_table) is
begin
-- iterate through all depts
for r_list in (select * from dept) loop
i := i + 1;
end loop;
end test_dept_table;
end ws_package;
Not sure if I am meant to do anything extra before I generate Web Service using JDeveloper if my procedure has got PL\SQL types as OUT parameters but as far as I know JDeveloper should do all the type conversions for you??
Thanks
Bojan

ClassDefNotFound Exception when calling PL/SQL Web Service

Hi to all J2EE'ers.
I'm trying to construct a sample PLSQL Web Service. I'm using a 10g R1 Database Server, Apache HTTP Server from the 10g Companion CD, and OC4J 9.0.4 (I think it's called "standalone" OC4J), all on Linux (Suse 9.1).
I set up a simple package on the DB server, containing a simple method named "get_payload(p_arg in varchar2) return varchar2".
Assembling and deploying worked well (i.e., java -jar WebServiceAssembler.jar -config config-payload.xml, followed by java -jar admin.jar ormi://localhost admin admin -deploy ... and -bindWebApp ...), and after deployment I am able to navigate to the service endpoint, but when trying to test the method named "getPayload(String param0)", after entering the parameter value and clicking "Invoke" I receive an error from the Web Server:
500 Internal Server Error

I scanned the web up and down to find references to similar problems, but to no avail. Any ideas how I could nail down the issue? WHAT class def can not be found? What code is around line 17 of StatelessStoredProcRpcWebService.java?
TIA for any input.

Help needed in web service example. Thank!!!

Hi,
I tested WebLogic 6.1 message-style web service example. For the
ProducerClient.java example, I tested successfully. But for
the ConsumerClient.java example, I kept getting error messages.
Can any expert offers some explanation or advice? Need to
show my boss the cool thing. Any help is highly appreciated.
Thanks.

PL/SQL Web services working with synonyms but not parameters Collection

Hi
I am Using JDeveloper 10.1.3.1.0
i could able to test successfully the PL/SQL web services with the synonyms.I created the PL/SQL web services in 'MKI' schema and then i dropped the objects from the MKI schema and launched the same in 'BAS' Schema and given grants to MKI schema and Created the Local synonyms in Schema 'MKI' and now when i test the PL/SQL web service, it is working successfully.
There was problem with passing the collection types as parameters in web services in that case it is giving the following Error
"Internal Server Error (Caught exception while handling request: java.rmi.RemoteException: java.sql.SQLException: Internal Error)"
Could any one suggest me the reason for the above error?
Regards
Malathi

Just a clarification about the problem.
Even though, if an exception is raised, the Connection object will be eventually closed(), it may take a while and if there are lots of users getting exceptions at the same time the connection pool can quickly run out of connections (correct me if I am wrong please.)
That is why we think the Connection object should be immediately closed in the case of an exception is raised and we are looking for a fix for this.
Thanks
Luis
