CMP example and Oracle

Hi,
I have problem with containerManaged bean. After succesfully created
connection pool I receive messages that container cannot map EJB attributes
to table columns.
Here are some parts of the log:
weblogic.ejb.common.DeploymentException: Could not setup the persistence
store for this bean.; nested exception is:
weblogic.cmp.rdbms.CMPStartupException: WebLogic RDBMS CMP could not be
started due to the following exceptions:
0 : Error in Weblogic CMP RDBMS deployment descriptor. Column 'bal',
referenced in attribute-map element, was not found in database table.
1 : Error in Weblogic CMP RDBMS deployment descriptor. Column 'id',
referenced in attribute-map element, was not found in database table.
2 : Error in Weblogic CMP RDBMS deployment descriptor. Column 'type
', referenced in attribute-map element, was not found in database table.
connection pool is connected to Oracle database via
weblogic.jdbc.oci.Driver.
Could anyone help me with that?

Thanks!
I solved the problem by following your advice.
I got to know the existence of config/server.xml.
I also got to know why so slow for the first time.
The connections in the connection pool is not made at the server starting time. It is made at the first use time. (first invoke).
In my PC, for between oracle and appserver, the connection making time takes about 33 seconds(?? - really high cost!). the default initial pool size was 8. So was 8*33 = 264 sec = 4.4 min.
Thanks.

Oracle Coherence Examples with Oracle SOA suite 11.1.1.4.0 and JDeveloper.

Hi,
I am new to Oracle Coherence. I was looking for examples implementing Oracle Coherence step by step so as to get a basic understanding using JDeveloper but most of the examples available are using Oracle Service Bus and Eclipse.
Could anyone please help me in providing link with examples using Oracle Coherence with Oracle SOA suite 11.1.1.4.0 and JDeveloper.
Thanks for the needful.
Cheers,
Varun

Hi Varun,
Please find the answers to your questions below:
1) Could you please let me know how to use this system property -Dtangosol.coherence.override in my application so that I can coordinate between the cluster used by my application and the one started for using Coherence Node.
You need to specify this property in the Java Options of your server or cache node startup script.
2) I was trying to understand how to use this tangosol-coherence-override.xml but the document is pretty confusing. I am not able to understand that whether I am suppose to use it at server level or at application level.
I would suggest extract the coherence.jar and you it would be important for you to have a look at the tangosol-coherence.xml and tangosol-coherence-override.xml. This file is used to override any of the properties specified in tangosol-coherence.xml for your cluster configuration for example, clustername, multicast ip and port or WKA for unicast, logging and so on.
3) Another point is how to coordinate among tangosol-coherence-override.xml, coherence-cache-config.xml and -Dtangosol.coherence.override system property from my application
Ideally you should specify in the java options of your application startup but you can also sepcify using System.setProperty("property", "value") in you code for specifying the various properties
4) How to use the cache updating mechanisms from an application?
I am not clear what do you mean by cache updating mechanisms? If you mean how you can update the cache from application then you can use simple Put, Entry Processor and so on. Refer NamedCache APIs to start with for operations but there many other ways to update the cache from within application or otherwise
Hope this helps!

Example of a successful reverse proxy to APEX using Apache and Oracle HTTP

If this helps anyone, I was able to set up a reverse proxy to APEX with Apache running on the reverse proxy server and Oracle HTTP server and APEX 3.2 on the APEX hosting server. I want to post this due to there is no
documentation on this that I can find. Oracle Metalink could not produce any "How To" document either.
On the reverse proxy server in the httpd.conf file:
ProxyRequests Off
SetEnv force-proxy-request-1.0.1
SetEnv proxy-nokeepalive 1
ProxyPassReverse /pls/apex/ http://apex_server:8080/pls/apex/
ProxyPass /pls/apex/ http://apex_server:8080/pls/apex/
ProxyPassReverse /i/ http://apex_server:8080/i/
ProxyPass /i/ http://apex_server:8080/i/
AddType text/xml .xbl
AddType text/x-component .htc
OR
ProxyRequests off
RewriteEngine On
RewriteRule ^/pls/apex/(.*)$ http://apex_server:8080/pls/apex/$1 [P,NE]
ProxyRequests off
ProxyPassReverse /i/ http://apex_server:8080/i/
RewriteEngine On
RewriteRule ^/i/(.*)$ http://apex_server:8080/i/$1 [P,NE]
And in the Oracle HTTP server httpd.conf file of the APEX hosting server:
NameVirtualHost 999.99.99.9:8080
<VirtualHost 999.99.99.9:8080>
ServerAdmin [email protected]
DocumentRoot "/u01/app/ora11g/product/11.1.0/http_1/ohs/htdocs"
ServerName reverse_proxy_server.com
</VirtualHost>

Here is what I saw :
I have one Web Server 7.0 instance with the following obj.conf :
<Object name="default">
<If $uri =~ "/xyz">
NameTrans fn="map" from="/" name="reverse-proxy-/xyz" to="/"
</If>
<ElseIf $uri =~ "/abc">

/abc/test1.html : the request gets served from server1 from docs/abc/test1.html.
/xyz/test2.html : the request gets served from server2 from docs/xyz/test2.html
Where as when you change obj.conf to (note the change in "from" parameter in "map" SAF)
<Object name="default">
<If $uri =~ "/xyz">
NameTrans fn="map" from="/xyz" name="reverse-proxy-/xyz" to="/"
</If>

</Object> ...In this case when I send a request to URI :
/abc/test1.html : the request gets served from server1 from docs/test1.html.
/xyz/test2.html : the request gets served from server2 from docs/test2.html.

Oracle Single Sign on and Oracle Internet Directory

Hello Gurus,
What is the relationship between Oracle Single Sign on and Oracle Internet Directory.
To my understanding, OID is required to install SSO.
If OID already exist, can we just install SSO and go on integrating it to existing OID.
Great Thanks,

Hi Tim,
I've been working on this and could reproduce the issue with anonymous binds. A fix will be ready in 4.2.1.
So what I really need is the password used for login to pass to the is_member call.The P101_PASSWORD item does not save state. However, you can access the value during submit processing of the login page, for example in the post authentication function of your authentication scheme. People sometimes put code in there to query the user's groups (e.g. with apex_ldap.member_of2) and save them in an application. This item value can then be used in the authorization schemes.
Regards,
Christian

Oracle Spatial and Oracle Forms

Hi,
Does anyone have experience with Oracle Spatial and Oracle Forms?
I have generated a form, which is based on a view. The view uses the mdsys.sdo_relate operator. Somehow I am unable to get the form to perform (to get one record it takes over 20 minutes). While useing sql-navigator to process the same statement it seems no problem. The query that also uses the view, is then processed in 10 seconds.
I also noticed that when text-functions like ' lower' of ' upper' are used to query the view, the query is processed within 15 seconds. If I don't use ' lower' or ' upper' it takes a long time (> 20 minutes) to process the query. Is it possible that this causes the bad performance of the form?
On metalink I have found that forms and spatial do not cooperate because of the pl/sql version that
forms6 uses. There is no solution presented, does anyone know of a work around?
My configuration is:
Oracle 8.1.7 on WIN2K @ PIII-800Mhz 256 Mb memory.
Formsbuilder 6
If requested I can post the queries that I have made.
With regards,

Limitation on SQL executing select statement from ADO and Oracle 8.1.7.1 OleDB Driver

Hi,
we are running a query with a big dunamic select statement from VB code using ADO command object. When Execute method is called system hangs and control won't return back to the application. it seems to be that there is some type limitation on Query string length. Please tell us if there is any?
we are running Oracle 8.1.7 Server on Windows 200 Server and connecting from a W2K professional, ADO 2.6 and Oracle OLEDB 8.1.7.1 OLEDB Driver.
Sample code:
Dim rs As ADODB.Recordset
Dim cmd As ADODB.Command
Set cmd = New Command
With cmd
.CommandText = ' some text with more than 2500 characters
.CommandType = adCmdText
Set rs = .Execute
End With
when i debug using VB6 and when .Execute line is called system hangs or return a message method <<somemethod> of <<some class name>> failed error.
Any help is appreciated.
Thanks,
Anil

A stored procedure would only slow you down here if it was poorly written. I suspect you want to use the translate function. I'm cutting & pasting examples from the documentation-- a search at tahiti.oracle.com will give you all the info you'll need.
Examples
The following statement translates a license number. All letters 'ABC...Z' are translated to 'X' and all digits '012 . . . 9' are translated to '9':
SELECT TRANSLATE('2KRW229',
'0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ',
'9999999999XXXXXXXXXXXXXXXXXXXXXXXXXX') "License"
FROM DUAL;
License
9XXX999
The following statement returns a license number with the characters removed and the digits remaining:
SELECT TRANSLATE('2KRW229',
'0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ', '0123456789')
"Translate example"
FROM DUAL;
Translate example
2229
Also, LIKE '%<string>%' is going to be rather expensive simply because it has to compare the entire string and because it forces full table scans, rather than using indexes. You could speed this sort of query up by using interMedia Text (Oracle Text now in 9i). If you can eliminate one of the '%' options, you could also improve things.
My guess is that your stored procedure is inefficient and that's causing the problem-- 5k rows per table should be pretty trivial.
If you post your query over on the PL/SQL forum, there are better performance tuners than I that might have more hints for you. To get really good advice, though, you'lllikely have to get at least the execution plan for this statement and may need to do some profiling to identify the problem areas.

New to XML and Oracle

Just trying to clarify some issues as I try and learn about XML, and specifically how it integrates into the DB.
1 - Is there a way with Oracle tools for me to get an XSD of an existing 9i relational schema? We are not currently using the XML DB, but our middleware developers would like to have an up to date XSD to use for their internal mapping.
2 - Is there any way that I can keep that XSD up-to-date automatically, so I get a new one whenever the schema gets updated?
3 - If I wanted to investigate storing XML docs within the DB in native XML format, I need to have an XML DB, correct? Is this DB construct maintained seperatelly from my "normal" relational schema? or are they kept in sync by Oracle?
I know these may all be real basic questions, but as I said, I'm new to XML and Oracle. I am reading as much as I can, but there are a lot of docs out there.
Thanks,
Mike

Hi
1. On my opinion such a tool doesn't exists. Some parts can be implemented elsewhere, but not as described by you... e.g. with XSU if you specify the parameter "withschema" the XSD of the executed statement is generated. Another example is to use DBMS_METADATA to dump the data dictionary in XML (but not XSD, of course you could write your own XSLT to do this transformation...).
2. -
3. If you use XSD-based tables the XSD and the relational model are stored separately in the data dictionary. Therefore if you change the XSD you have to drop/create the XSD-based table... no schema evolution yet.

Problem with Unicode and Oracle NCLOB fields

When I try to INSERT a new (N)CLOB into an Oracle database, all is fine until I use a non-ASCII character, such as an accented roman letter, like the "�" (that's '\u00E9') in "caf�" or the Euro Currency symbol "?" (that's '\u20AC' as a Java character literal, just in case the display is corrupted here too). This doesn't happen with "setString", but does happen when streaming characters to the CLOB; however, as Oracle or the driver refuse strings larger than 4000 characters, and as I need to support all the above symbols (and many more), I'm stuck.
Here's the background to the problem (I've tried to be detailed, after a lot of looking around on the web, I've seen lots of people with similar problems, but no solutions: I've seen and been able to stream ASCII clobs, or add small NCHAR strings, but not stream NCLOBs...).
I'm using Oracle 9.2.0.1.0 with the "thin" JDBC driver, on a Windows box (XP Pro). My database instance is set up with AL32UTF8 as the database encoding, and UTF8 as the national character set.. I've created a simple user/schema, called LOBTEST, in which I created two tables (see below).
The basic problems are :
- with Oracle and JDBC, you can't set the value of a CLOB or NCLOB with PreparedStatement's setString or setCharacterStream methods (as it throws an exception when you send more than 4000 characters)
- with Oracle, you can only have one LONG VARCHAR-type field per table (according to their documentation) and you MUST read all columns in a set order (amongst other limitations).
- with a SQL INSERT command, there's no way to set the value of a parameter that's a CLOB (implementations of the CLOB interface can only be obtained by performing a SELECT.... but obviously, when I'm inserting, the record doesn't exist yet...). Workarounds include (possibly) JDBC 4 (doesn't exist yet...) or doing the following Oracle-specific stuff :
INSERT INTO MyTable (theID,theCLOB) VALUES (1, empty_clob());
SELECT * FROM MyTable WHERE theId = 1;
...and getting the empty CLOB back (via a ResultSet), and populating it. I have a very large application, that's deployed for many of our customers using SapDB and MySQL without a hitch, with "one-step" INSERTS; I can't feasibly change the application into "three-step INSERT-SELECT-UPDATE" just for Oracle, and I shouldn't need to!!!
The final workaround is to use Oracle-specific classes, described in:
http://download-east.oracle.com/otn_hosted_doc/jdeveloper/904preview/jdbc-javadoc/index.html
...such as CLOB (see my example). This works fine until I add some non-ASCII characters, at which point, irrespective of whether the CLOB data is 2 characters or 2 million characters, it throws the same exception:
java.io.IOException: Il n'y a plus de donn?es ? lire dans le socket
     at oracle.jdbc.dbaccess.DBError.SQLToIOException(DBError.java:716)
     at oracle.jdbc.driver.OracleClobWriter.flushBuffer(OracleClobWriter.java:270)
     at oracle.jdbc.driver.OracleClobWriter.flush(OracleClobWriter.java:204)
     at scratchpad.InsertOracleClobExample.main(InsertOracleClobExample.java:61)...where the error message in English is "No more data to read from socket". I need the Oracle-specific "setFormOfUse" method to force it to correctly use the encoding of the NCLOB field, without it, even plain ASCII data is rejected with an exception indicating that the character set is inappropriate. With a plain CLOB, I don't need it, but the plain CLOB refuses my non-ASCII data anyway.
So, many many thanks in advance for any advice. The remainder of my post includes my code example and a simple SQL script to create the table(s). You can mess around with the source code to test various combinations.
Thanks,
Chris B.

The solution to this is to use a third-party driver. Oranxo works really well.

Using Coherence and Oracle Database as the CacheStore

We are working on implementing a solution using Coherence and Oracle Database as the CacheStore. We initially implemented the Cache as a distributed-scheme which in turn uses the backing-map-scheme. We are trying to introduce transaction management and I used a scheme-ref in a transactional-scheme to point to an already existing distributed-scheme. However when I bring up the server, my custom coherence-cache-config.xml file is not recognized and Coherence comes up with the default setting. Given below is the snippet of my configuration file.
1)     I would like to understand why the below configuration doesn’t work and am I doing it the right way? If not, what is the correct way of doing it?
2)     There are a multiple transaction management options given in the documentation. Which are the ones that will work with a distributed-scheme and read-write-backing-map-scheme?
3)     If transactional-schemes cannot work with distributed-scheme, what is the best way to have a distributed cache with a oracle database as a cache store?

Hi,
If you look at the documentation for transactional-scheme here: http://docs.oracle.com/cd/E24290_01/coh.371/e22837/appendix_cacheconfig.htm#BHCIABHA
you will see that it says The transactional-scheme element defines a transactional cache, which is a specialized distributed cache. That means that a transactional-scheme is already a distributed-scheme.
You will see from the same documentation above that there is no way in a transactional-scheme to configure things like cache-stores or listeners or even the backing-map-scheme as these are not supported on a transactional-scheme - so you cannot use a cache store.
Personally I would not use transactional-scheme unless you have some really big reason to do so - the restrictions far outweigh any perceived advantage of having a transaction. There are better ways to build applications so they do not require transactions, that is what we have been doing for years with Coherence so far, and there is no real reason to change that.

Different between Oracle 8.1.7.0.0 and Oracle 8.1.7.2 ?

1) Hi all, i have some doubt about the oracle versioning technique. For example, i had installed oracle 8.1.7 release 3 in a SUN Solaris version 8 and the database character set is in UTF-8. Then i select sql : "Select * from product_component_version" and the result is "Oracle8i Enterprise Edition 8.1.7.0.0 ". What does that means ? Our DBA in another location had installed the oracle 8.1.7 release 2 in their db server with the same OS and same database character set which is UTF-8. But the result from the "Select * from product_component_version" is "Oracle8i Enterprise Edition 8.1.7.2 ".
So as a conclusion, i had confused about the oracle versioning technique, can somebody please explain to me ?
2) My second problem is actually related to problem stated above (1). In the Oracle 8.1.7 release 2 database,
when i select a clob/blob value for update, i sometimes encountered the problem as follows but in our Oracle 8.1.7 release 3 the problem didn't exist at all after investigating that all the java code and other factor remain the same but not the oracle version.
java.io.IOException: ORA-22990: LOB locators cannot span transactions

This was an error log in our backend log and in the web browser it showed "Request Timeout" in both IE and Netscape. We are using J2EE, Oracle DBMS and IBM Websphere App Server for our e-commerce system.
But retrying the request sometimes may work but most of the time failed.
The above error didn't exist in our server using Oracle version 8.1.7 release 3 (8.1.7.0.0) and Oracle
version 8.1.6.0.0. But ORacle version 8.1.7.2 release 2 is encountering this problem now.
Somebody please help me on this problem, our developers and DBA had try to solved this problem one week ago but still don't know what is the cause.

Oracle 9i client would fit you well. You need ORACLE_HOME set, ORACLE_HOME/bin in the path variable and of cource check that the user has access there. Are you using OCI to connect to Oracle? JDBC thin client is a better approach, in my opinion, as it is pure java.
Oracle also provides something called "instant client", which provides connectivity only for applications.

Out of memory using Windows Server 2003 and Oracle 9.2.0.3

Hi,
I just installed both Windows Server 2003 and Oracle 9.2.0.3. The server I am using has 4 gigabytes of memory installed, and windows shows that to be the actual physical memory on the server. The paging file is 8 gigabytes for a total of 12 gigabytes of virtual memory.
Using the Oracle Database Configuration Assistant, I create a new database using default values. After verifying the installation worked OK (database started, queries ran), I attempted to change some of the memory parameters and was able to start the database using about 1.4 gigabytes of total SGA, with the O/S using about .3 gigabytes for a total of 1.7 gigabytes. I then attempted to change the buffer cache + 1 gigabyte for a total of 2 gigabytes. Now the database will not start and I get an out of memory error ora-27102 with an additional O/S memory error of "O/S Error: (OS 8) Not enough storage is available to process this command".
So, I have two problems:
1) With 4 gigabytes installed, and the O/S using only about 300 megabytes, why isn't Oracle able to take advantage of the memory on this machine past the 1.7 gigabytes (as reported by Windows task manager).
2) How do I change the spfile memory parameters so the database will start using spfile? I can start the database pointing to a pfile with lesser memory parameters, but I don't know how to effect change on the spfile, since I cannot start with the spfile.
Both these technologies (9.2.0.3 and Server 2003) are new to me, so any insight would be appreciated!

CREATE SPFILE
Purpose
Use the CREATE SPFILE statement to create a server parameter file from a client-side initialization parameter file. Server parameter files are binary files that exist only on the server and are called from client locations to start up the database.
Server parameter files let you make persistent changes to individual parameters. When you use a server parameter file, you can specify in an ALTER SYSTEM SET parameter statement that the new parameter value should be persistent. This means that the new value applies not only in the current instance, but also to any instances that are started up subsequently. Traditional client-side parameter files do not let you make persistent changes to parameter values. Because they are located on the server, these files allow for automatic database tuning by Oracle and for backup by Recovery Manager (RMAN).
To use a server parameter file when starting up the database, you must create it from a traditional text initialization parameter file using the CREATE SPFILE statement.
All instances in an Real Application Clusters environment must use the same server parameter file. However, when otherwise permitted, individual instances can have different settings of the same parameter within this one file. Instance-specific parameter definitions are specified as SID.parameter = value, where SID is the instance identifier.
The method of starting up the database with a server parameter file depends on whether you create a default or nondefault server parameter file. Please refer to "Creating a Server Parameter File: Examples" for examples of how to use server parameter files.

Prerequisites
You must have the SYSDBA or the SYSOPER system privilege to execute this statement. You can execute this statement before or after instance startup. However, if you have already started an instance using spfile_name, you cannot specify the same spfile_name in this statement.
Syntax
create_spfile::=
Text description of create_spfile
Semantics
spfile_name
This clause lets you specify a name for the server parameter file you are creating.
If you do not specify spfile_name, Oracle uses the platform-specific default server parameter filename. If spfile_name already exists on the server, this statement will overwrite it. When using a default server parameter file, you start up the database without referring to the file by name.
If you do specify spfile_name, you are creating a nondefault server parameter file. In this case, to start up the database, you must first create a single-line traditional parameter file that points to the server parameter file, and then name the single-line file in your STARTUP command.
See Also:
"Creating a Server Parameter File: Examples" for information on starting up the database with default and nondefault server parameter files
Oracle9i Database Administrator's Guide for Windows (or other appropriate operating system specific documentation) for default parameter file names
pfile_name
Specify the traditional initialization parameter file from which you want to create a server parameter file.
If you specify pfile_name, the parameter file must reside on the server. If it does not reside in the default directory for parameter files on your operating system, you must specify the full path.
If you do not specify pfile_name, Oracle looks in the default directory for parameter files on your operating system for the default parameter filename, and uses that file. If that file does not exist in the expected directory, Oracle returns an error.
Note:
In a Real Application Clusters environment, you must first combine all instance parameter files into one file before specifying it in this statement to create a server parameter file. For information on accomplishing this step, see Oracle9i Real Application Clusters Setup and Configuration.
Examples
Creating a Server Parameter File: Examples
The following example creates a default server parameter file from a client initialization parameter file named t_init1.ora:
CREATE SPFILE
FROM PFILE = '$ORACLE_HOME/work/t_init1.ora';
Note:
Typically you will need to specify the full path and filename for parameter files on your operating system. Please refer to your Oracle operating system documentation for path information.
When you create a default server parameter file, you subsequently start up the database using that server parameter file by using the SQL*Plus command STARTUP without the PFILE parameter, as follows:
STARTUP
The following example creates a nondefault server parameter file s_params.ora from a client initialization file named t_init1.ora:
CREATE SPFILE = 's_params.ora'
FROM PFILE = '$ORACLE_HOME/work/t_init1.ora';
When you create a nondefault server parameter file, you subsequently start up the database by first creating a traditional parameter file containing the following single line:
spfile = 's_params.ora'
The name of this parameter file must comply with the naming conventions of your operating system. You then use the single-line parameter file in the STARTUP command. The following example shows how to start up the database, assuming that the single-line parameter file is named new_param.ora:
STARTUP PFILE=new_param.ora

Help building an e-commerce site using DreamWeaver MX 2004 and Oracle 10G

I'm new to using Oracle 10G. After reviewing several rdms's I've picked Oracle 10G as my rdms. I'm trying to build an ecommerce site using DreamWeaver MX 2004 and Oracle 10G. The website will be selling hardware and software products. I have a choice in DreamWeaver to go for a .asp or .jsp setup. I have several questions, here goes:
1. Is there any book/tutorial/whitepaper out there that describes building an ecommerce site using Oracle 10G/9I/8I? Just some examples as how to make the datamodel regarding the shopping basket etc.
2. I prefer DreamWeaver as it let's me make nice looking css style based pages without throttling too much through the code. Are there Oracle tools which allow me to make an advanced nice looking ecommerce site?
I hope some of you can help me get started. Any effort is appreciated.
Cheers

Linking Access tables, creating a query with using both Access and Oracle

Hello,
I am using 3.0.04.34 version Oracle Developer. I am supposed to create a script/procedure to use both Access tables and oracle tables together. There is an option in developer to copy the access tables into oracle. But it doesn't help me. Because when we updated the access tables
the copied ones are not be updated. How can I created a linked access tables to oracle and create a query with using both access and oracle table together.
I will appreciate if you guys help me. I look forward to hearing from you guys.
Thanks,
Pinar

Pinar,
to be able to query MS Access tables in Oracle you need an additional product, the Oracle Database Gateway for ODBC. It allows you to link any foreign database into an Oracle database using a suitable ODBC driver. You can then access the MS Access tables through a database link based on the Database Gateway for ODBC. This will also allow you to join local Oracle and remote MS Access tables from your Oracle database.
There's a note on My Oracle Support which gives you more details:Document 233876.1 Options for Connecting to Foreign Data Stores and Non-Oracle Databases - For example - DB2, SQL*Server, Sybase, Informix, Teradata, MySQL
And there's also a dedicated Forum: Heterogeneous Connectivity

Hi,
Is there any sample code showing PAPI-WS with VS 2008? AFAIK, there is a sample using VS 2005 and WSE 3.0, but I'm interested in using VS 2008/WCF.

Dan,
I tried in both studio and Standalone.
From Studio :*
1. The Url for the Webservice is (http://localhost:8585/papiws/PapiWebServiceEndpoint?wsdl). From studio by default port number was 8585.From this studio wsdl URL(http://localhost:8585/papiws/PapiWebServiceEndpoint?wsdl),I did n't see any wsdl text in the browser.
From Standalone :*
1. In BPM Admin Center, I have selected *"PAPI Web Services"* check box(Page 5 of your document).
2. In The BPM Admin Center, I have clicked on *"Start BPM Web Applications"*.
3. After Stand alone server started *"Launch PAPI WebServices Console"* link was enabled,And I clicked on that link.It opened a browser with URL (http://localhost:8686/papiws/PapiWebService)
