Problems publishing PL/SQL using JPublisher

Hi
I'm simply trying to publish a test pl/sql package using JPublisher from a client command line without success. I've defined my Classpath as follows:
CLASSPATH=.;%ORACLE_HOME%\LIB\xmlparserv2.jar;
%ORACLE_HOME%\jdbc\lib\ojdbc14.jar;
%ORACLE_HOME%\jdbc\lib\orai18n.jar;
%ORACLE_HOME%\sqlj\lib\translator.jar;
%ORACLE_HOME%\sqlj\runtime12.jar;
%ORACLE_HOME%\sqlj\runtime12ee.jar;
Note that I have put the first entry for the xmlparserv2.jar here in response to the resulting error I get after running the following jpub invocation:
C:\10GIDS\BIN>jpub -u XMLDBMASTER/password -sql=JOHN_TEST(testReturnXML) -url=jdbc:oracle:oci:@stir-db-orc01:1521/C02D
The response is:
NOTE: xmlparserv2.jar missing in CLASSPATH, SQL-Java type mapping for SYS.XMLTYPE skipped.
XMLDBMASTER.JOHN_TEST

at oracle.jpub.publish.Main.main(Main.java:9)
at oracle.jpub.Main.main(Main.java:6)
I'm no java programmer and wondered what the error message really points to: is it directly related to the fact that the Function in the package returns an XMLTYPE and it can't see the xmlparserv2.jar (which I plainly have in the CLASSPATH) i.e.can't deal with XMLTYPES?
I've spent a lot of time on this and really need to get things moving, can anyone help?

God bless you for that, couldn't see the wood for the trees....the allusion to the missing xmlparserv2.jar file still remains though - is there any obvious reason why this is? even though I've explicitly entered it in my CLASSPATH?

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

Hello,
The OracleAS Database Web Service is only available for OracleAS using the Oracle Web Service runtime and tools as documented here.
If you are not using OracleAS or if you want to use another Web Service stack you can still manually program you Web Service manually using JDBC and is features.
Here a generic article: http://www.onjava.com/pub/a/onjava/2003/08/13/stored_procedures.html
and you can use advanced features of JDBC and JPublisher if needed:

Using JPublisher with Oracle 10g

Hello all,
I am trying to generate a PL/SQL wrapper using JPublisher for the stock quote web service given in the example documentation. I have loaded the dbwsclient.jar using the loadjava utility, and I have set the classpath with all the jar files utl_dbws.jar, dbwsa.jar, translator.jar, runtime12.jar, runtime12ee.jar etc. Still, when I run the jpub command, I get the following error:
"Cannot run CompileTool for the given wsdl file. Please make sure sqlj\lib\utl_dbws.jar exists and if in the classpath".
I have specified this in the classpath, but I still get the error. Can someone help me out with this. Thanks in advance.

Hi,
I want to know if you find out the solution finally because I have the same problem.

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.

Publish PL/SQL as Web Service

I am new to Oracle Web Service. I went through Publish PL/SQL as Web Service tutorial and tested from browser. When I tested by
http://127.0.0.1:8888/PLSQL-PLSQL-context-root/my.CompanyWebService
I got following message:
"Error parsing the WSDL for this endpoint.
oracle.wsdl.internal.WSDLException: oracle.xml.parser.v2.XMLParseException: Start of root element expected."
I was able to display WSDL somehow by
http://127.0.0.1:8888/PLSQL-PLSQL-context-root/my.CompanyWebService?WSDL
I have no clue what is the problem. Please help.
Thanks.

Hi,
The problem could be because of wrong JDK version. Looks like you are using JDK1.4.2. Could you try checking with JDK 1.3.x
If you still face problems, specify your environment details and at what stage you are getting the error.

Report To Show SQL Used In A Report

I am creating a set of quality reports using the apex views.
I would like to create a report to check the sql used in classic reports, but can't seem to find the right view to use.
If it was a interactive report I would use the SQL_QUERY column in the APEX_APPLICATION_PAGE_IR view, but this does not seem to exist for classic reports
Help appreciated.

You can use the Data dictionary view APEX_APPLICATION_PAGE_REGIONS. There's a field called "REGION_SOURCE" - just filter for the appropriate region type.

Having a brief look through your list of recently answered questions, you don't seem to award helpful points, even when you've explicitly saying (paraphrasing) "Thanks for your help". Maybe it's a tipping thing - perhaps you subscribe to the doctrine of Mr. Pink but, hey if it helps you get your question answered and it literally costs you nothing but a few seconds of effort, why not throw us a bone by awarding a point now and then?

Run a report in PL/SQL using utl_http.request

Hi
I need to run a report in PL/SQL using utl_http.request
How that can be done ??
Thank you!

Okay, backtrack.
A web server can deliver all kinds of content. From static HTML pages, to XML files and videos and dynamic content. Including reports.
The communication language (protocol) used to talk to a web server is HTTP.
UTL_HTTP is an Oracle PL/SQL library that implements the client side of this communication. It allows the developer to write code that acts like a web browser and communicates with a web server.
Now what do you not understand and cannot use?
HTTP is not simple and easy. You need to understand the basics of this communication language in order to communicate successfully with the web server. Like knowing the difference between GET and PUT and POST commands, how the URL query string works and so on.
Once you know that, you can look at how the web server provides reports. How do you authenticate as a web browser with the web reporting system? What URLs do you use to access which reports? How do you pass name-values to the web server as report parameters? What HTTP response formats (MIME types) does the web report server provide? Which one do you plan to use and how do you parse that response into a meaning structured data format?
If you're thinking it is "easy", think again. Sure, someone here can provide sample code that for example grabs a CSV report file from a web server and (using a pipeline table function), turn that into rows and columns. But that will not teach you the fundamentals you need to know and not equip you with dealing with the problem with your own brains, hands and keyboard.
PS. In other words, learn to crawl and walk before trying to run. Get to grips with how HTTP works before diving into the deep end of web report integration.

Problems publishing shared review comments in Acrobat 8.0

I created a shared review in Acrobat 8.0 and posted it to a Sharepoint workspace. A reviewer published comments but I was not able to see them. He double-checked, and he was able to see his comments but I was still unable to see them. He checked again, and was not able to see his comments.
I can see comments the reviewer published on a different date, but the reviewer is no longer able to see those comments either. Has anyone had a similar experience?

I'm having a similar problem and didn't see a solution posted.
I'm using Acrobat 8 Professional to do shared document reviews. I created a sharepoint shared documents folder which the shared document review process verified and accepted as a destination.
I used the Review and Comment process to save the pdf document to the folder (enabling those using Reader to review and comment) and send an email inviting specific individuals to review and comment.
The problem is when they open the document (using the URL in the email) they don't see the "toolbar" that lets them Publish Comments to Server. They all have Reader 9.
Until I figure out what the problem is, I'm using a brute force technique to force publishing comments, instructing them to close the browser and then Publish Comments using the dialog box that appears after the browser has closed.
Any suggestions how to get the toolbar that lets them look for published comments and publish their comments to display ?

Problems with PL/SQL packages

Hello,
I face the following problem with PL/SQL stored procedures. The Oracle
version is 8.0.5 on Windows NT 4. The PL/SQL package has a set of procedures and functions.
The main procedure of the PL/SQL package is triggered from VC++ executable. If for some reason,
an exception is caught in the stored procedure (like no_data_found
exception), then the following problem occurs.
If we try to trigger the stored procedure again through the VC++ executable,
the variables in the stored procedures have the values as in the previous
execution. They are not getting initialised. (The same database connection
is used in VC++ executable).
Currently, only if a new connection to the database is used , the problem is
solved.
Also, change in the input parameters of the procedure is not reflected, once the procedure fails because of any exception. Only the input which was given during the time of execution when the procedure failed,is considered.
What could be the reason for this problem and how can this be corrected?
Please send in your suggestions.
Thanks and Regards,
Ramya Priya

Hi Keith,
I am connecting to the database as the package owner..
I have noticed earlier that I have problems when capturing triggers also.. The content of one large trigger contains 36371 characters and when capturing it from DB, the content was truncated to 28020 characters in Designer.
Our ideas with capturing the DB packages/procedures were to use the Designer as version control system.
We wanted to have all objects used in a project in Designer.. entities, tables, triggers, packages, procedures, Forms files, etc. in order to make a configuration for a project release.
Thank you,
Claudia

How to avoid performance problems in PL/SQL?

How to avoid performance problems in PL/SQL?
As per my knowledge, below some points to avoid performance proble in PL/SQL.
Is there other point to avoid performance problems?
1. Use FORALL instead of FOR, and use BULK COLLECT to avoid looping many times.
2. EXECUTE IMMEDIATE is faster than DBMS_SQL
3. Use NOCOPY for OUT and IN OUT if the original value need not be retained. Overhead of keeping a copy of OUT is avoided.

Susil Kumar Nagarajan wrote:
1. Group no of functions or procedures into a PACKAGEPutting related functions and procedures into packages is useful from a code organization standpoint. It has nothing whatsoever to do with performance.
2. Good to use collections in place of cursors that do DML operations on large set of recordsBut using SQL is more efficient than using PL/SQL with bulk collects.
4. Optimize SQL statements if they need to
-> Avoid using IN, NOT IN conditions or those cause full table scans in queriesThat is not true.
-> See to queries they use Indexes properly , sometimes Leading index column is missed out that cause performance overheadAssuming "properly" implies that it is entirely possible that a table scan is more efficient than using an index.
5. use Oracle HINTS if query can't be further tuned and hints can considerably help youHints should be used only as a last resort. It is almost certainly the case that if you can use a hint that forces a particular plan to improve performance that there is some problem in the underlying statistics that should be fixed in order to resolve issues with many queries rather than just the one you're looking at.

Problem in JDBC , when using LIKE operator. - VERY URGENT

Problem in JDBC , when using LIKE operator.
LINE 1 : String temp = "AA";
LINE 2 : String query = "select * from emp where EMPNAME like '*temp*' ";
LINE 3 : Staement st = con.createStaement();
LINE 4 : ResultSet rs = st.executeQuery(query);
'*' character is not getting evaluated. In MS ACCESS2000 only * is accepted instead of '%'. Moreover in MS ACCESS the like operator has to be used within double quotes as a String. whereas in other databases, it accepts single quotes as a String.
Ex:
In MS ACCESS
     select * from emp where ename like "*aa*";
Other Databases
     select * from emp where ename like '%aa%';
In my situation iam passing a Variable inside a like operator and '*' is used.
For the above Scenario, Please help me out.
If possible Kindly let me know the exact Syntax.
Please give me the answer as LINE1,LINE2,LINE3,LINE4,
I have verified in JDBC Spec also, it has been specified to use escape sequence.that too did not work.
Due to this, My project is in hold for about 4 days. I could not find a suitable solution.
Please help me out.

I made a LIKE clause work with M$ Access, using PreparedStatement and the % wildcard:
            escapeStr                   = "%";
            String sql                  = "SELECT USERNAME, PASSWORD FROM USERS WHERE USERNAME LIKE ?";
            PreparedStatement statement = connection.prepareStatement(sql);
            statement.setString(1, ("user" + escapeStr));
            ResultSet resultSet         = statement.executeQuery();
            while (resultSet.next())
                System.out.println("username: " + resultSet.getObject("USERNAME") + " password: " + resultSet.getObject("PASSWORD"));
