Can, any one help to solve this error.

What does your code look like?
By the error it appears you are trying to access a field called "FAULT_CODE_IOEXCEPTION" which doesn't exist.

Reg@ Dynamic invocation of Webservices using an Single Invoke

Hi ,
I am trying to implement Dynamic invocation of webservices using a single Invoke .
Say , i have three webservices = WebA,WebB and Webc .Based on Logic , i need to invoke either of the webservice with an single Invoke .
In [ ws-addressing.xsd ] there are different elements ,"Address" is for endpoint URL.PortType??ServiceName ?? .
If i need to make use of this XSD can any one help me to map the WSDL components to this XSD Or lease suggest options if any ??

see the article he's refering too
eventually you need something like :

<EndpointReference xmlns="http://schemas.xmlsoap.org/ws/2003/03/addressing">
<Address>http://localhost:9700/orabpel/default/UnitedLoan</Address>

After Effects won't close/Problems with dynamic links

When I quit After Effects the icon still shows up and it says that it is still open, even force quit will not work. Also having problems with dynamically linked files between after effects and Premiere pro. Rendering in Premiere doesn't work unless I go to AE, save the project, then go back to Premiere. I have OSX Mavericks 10.9.2, a late 2012 mac pro, and AE CC 12.2.1.5

Kevin: would appreciate further thoughts on this.
I am using Pr2014, version 8.0.0 I am using AE2014, version 13.0.2.3. When I was on earlier versions of each, I had no problem importing AE comps into Pr. I'd choose import in Pr, then select the AE project, then select the comp. But with my new and improved versions of AE and Pr, I keep getting "importer reported a generic error."
I also tried to go the other way. I selected in Pr the clips I wanted to work on in AE, and then tried "replace with AE comp" but got the "generic error" message again..
Finally, I attempted to create a Dynamic Link from Pr via the File menu, but with each of the options from there, I got "failed to connect to AE Dynamic Link"
Any advice you can share, would be most welcome.

Problem with dynamic LOV and function

Hello all!
I'm having a problem with a dynamic lov in APEX 3.0.1.00.08. Hope you can help me!
I have Report and Form application. On the Form page i have a Page Item (Popup Key LOV (Displays description, returns key value)).
When i submit the sql code in the 'List of vaules defention' box. I get the following message;
1 error has occurred
LOV query is invalid, a display and a return value are needed, the column names need to be different. If your query contains an in-line query, the first FROM clause in the SQL statement must not belong to the in-line query.
When i excecute the code below in TOAD or in the SQL Workshop it returns the values i want to see. But somehow APEX doesn't like the sql....
SELECT REC_OMSCHRIJVING d, REC_DNS_ID r FROM
TABLE(CAST(return_dns_lov_fn(:P2_DNS_ID) AS dns_table_type)) order by 1
returns_dns_lov_fn is a function, code is below;
CREATE OR REPLACE FUNCTION DRSSYS.return_dns_lov_fn (p2_dns_id number)
RETURN dns_table_type
AS
v_data dns_table_type := dns_table_type ();
BEGIN
IF p2_dns_id = 2
THEN
FOR c IN (SELECT dns_id dns, omschrijving oms
FROM d_status dst
WHERE dst.dns_id IN (8, 10))
LOOP
v_data.EXTEND;
v_data (v_data.COUNT) := dns_rectype (c.dns, c.oms);
END LOOP;
RETURN v_data;
END IF;
END;
and the types;
CREATE OR REPLACE TYPE DRSSYS.dns_rectype AS OBJECT (rec_dns_id NUMBER, rec_omschrijving VARCHAR2(255));
CREATE OR REPLACE TYPE DRSSYS.dns_table_type AS TABLE OF dns_rectype;
I tried some things i found on this forum, but they didn't work as well;
SELECT REC_OMSCHRIJVING display_value, REC_DNS_ID result_display FROM
TABLE(CAST(return_dns_lov_fn(:P2_DNS_ID) AS dns_table_type)) order by 1
SELECT REC_OMSCHRIJVING display_value d, REC_DNS_ID result_display r FROM
TABLE(CAST(return_dns_lov_fn(:P2_DNS_ID) AS dns_table_type)) order by 1
SELECT a.REC_OMSCHRIJVING display_value, a.REC_DNS_ID result_display FROM
TABLE(CAST(return_dns_lov_fn(:P2_DNS_ID) AS dns_table_type)) a order by 1

I just had the same problem when I used a function in a where clause.
I have a function that checks if the current user has acces or not (returning varchar 'Y' or 'N').
In where clause I have this:
where myFunction(:user, somePK) = 'Y'
It seems that when APEX checked if my query was valid, my function triggered and exception.
As Varad pointed out, check for exception that could be triggered by a null 'p2_dns_id'
Hope that helped you out.

Oracle 9i, Rel.2 - Problems with dynam statement and cursor

Hello,
I have the following problem with Oracle 9i, Release 2:
I have a SQL-statement, which I create with the help of a configuration table. That means I don’t know how this statement looks at runtime. It could be look like this:
SELECT Att1, Att2, Att3
FROM Tab1
or this…
SELECT Att1, Att2
FROM Tab1
or this…
SELECT Att1
FROM Tab1
etc.
That means I don’t know in advance how many columns will be in the select-clause.
Here my code snippet until here:
v_query_str := 'SELECT ' || v_select_clause_str
|| ' FROM cb.' || v_table;
,,v_select_clause_str" willl be created dynamically
,,v_table" is as well from the config-table
Now I want to iterate through the result of the query and do further processing.
For this reason I wanted to use a cursor, iterate through the rows and save every value of each row in an own variable (but I don’t know the number of columns!!!).
But how can I open a cursor and iterate through it without knowing the number of columns???
The following code is NOT working:
TYPE t_dataColumnComp IS TABLE OF VARCHAR2(200);
a_dataColumnComp t_dataColumnComp;
--here I create the query…
v_query_str := 'SELECT ' || v_select_clause_str
|| ' FROM cb.' || v_table;
OPEN c_tempAtt FOR v_query_str;
LOOP
FETCH c_tempAtt INTO a_dataColumnComp; --THIS DON’T WORK
EXIT WHEN c_tempAtt%NOTFOUND;
FOR i IN 1..a_dataColumnComp.COUNT
LOOP
DBMS_OUTPUT.PUT_LINE(a_dataColumnComp(i));
END LOOP;
END LOOP;
CLOSE c_tempAtt; --close cursor variable
Regards
Homer

You will need to use DBMS_SQL to handle this since the number of columns in the result set is not known until runtime.
See here for an example of using DBMS_SQL:

DB2 problems with Dynamic SQL

Does anyone out there use dynamic SQL with DB2? If so, are the sql statements causing a PreparedStatement to be executed on DB2. I posted this question similarly before, but never resolved it, and it is killing me. I have to resolve this ASAP!
Here is the problem: My DB2 Admin says that EVERY TIME I access the database, my Java app is causing the database to create a PreparedStatement. However, I'm using Statement objects exclusively, with dynamic SQL. He says that DB2 needs an "access path" for the client, and that it converts the Statement to a PreparedStatement, as this is the only way to get this "access path". He says the only solution is either stored procedures or SQLJ, which will do the binding in advance, and increase performance tremendously. However, I am STRONGLY opposed to using SQLJ, and if we do stored procedures, we'd have to write one for every possible SQL statment! I KNOW there is a better solution.
Is anyone out there having these problems with JDBC and DB2? Surely someone out there uses DB2 and JDBC and either has these problems or can confirm that something is incorrectly configured on the database side.
Any help would be great. Thanks, Will

Now I'm wondering if maybe the PreparedStatements are ONLY being called on the database when I call getConnection(), and not when I call executeQuery() or executeUpdate() from the Statement object. I just can't see why the database would have to make an access path for every SQL statement executed, but I could see it creating an access path for every connection requested. Any thoughts on that theory?

Problem with Dynamic Node & UI Elements

Hi,
                                        The scenario is to create an Questioaire.Since the number questions which I get from R/3 may vary, I have created the Dynamic Node which is mapped with Dynamic set of Radio button Group by index for options & Dynamic text view for displaying Questions.. A New Dynamic Node will be created for each set of Questions .The Number of questions displayed per page is controlled by the Static Counter Variable....
                                          Now the issue is ,if i click back button the count will be initialized so again it needs to trigger the DoModifyView(). at that time It is arising an exception "Duplicate ID for view & Radio button ..." because while creating Dynamic node i used to have "i" value along the Creation of node name...
for(i=Count;i<i<wdContext.nodeQuestions().size();i++)
               customnod=<b>nodeinfo.getChild("Questionaire"+i);</b>
                    if(customnod==null)
Its not possible to create a new node whenever i click the Back button.
At the same time i am not able to fetch the elements which had already created Dynamically...
How do i make the Next & back button work?
If anyone bring me the solution It would be more helpful to me.
Thanks in advance..
Regards,
Malar

Hi,
      We can Loop through the Node Elements but how can we do Option Button Creation for each set of question Options?. At design time we can not have the radio buttons,because we do not know how many set of questions are available at the Backend.

Problem with Dynamically accessing EJB Class objects in WL 7.0 SP1

I am trying to build a component which has the ability to instantiate and execute
an known EJB method on the fly.
I have managed to build the component but when I try and execute it I get a ClassNotFoundException.
I know that the EJB I am trying to invoke is deployed and available on the server,
as I can see it in the console, I also seen to have been able to get the remote
interface of the object, my problem occurs when I try and access the class object
so I can perform a create on the object and then execute my method
The code I have written is below:
private Object getRemoteObject(Context pCtx, String pJNDIName, String pHomeBean)
throws Exception {
     String homeCreate = "create";
     Class []homeCreateParam = { };
     Object []homeCreateParamValues = {};
try {
//This call seems to work and doesn't throw an exception
Object home = pCtx.lookup(pJNDIName);
//However this call throws a java.lang.ClassNotFoundException
Class homeBean = Class.forName(pHomeBean);
Method homeCreateMethod = homeBean.getMethod(homeCreate,homeCreateParam);
return homeCreateMethod.invoke(home, homeCreateParamValues);
} catch (NamingException ne) {
logStandardErrorMessage("The client was unable to lookup the EJBHome.
Please make sure ");
logStandardErrorMessage("that you have deployed the ejb with the JNDI
name "+pJNDIName+" on the WebLogic server ");
throw ne;
} catch (Exception e) {
logStandardErrorMessage(e.toString());
throw e;
Any advice would be really appreciated, I'm fast running out of ideas, I suspect
it has something to do with the class loader but I'm not sure how to resolve it
Regards

Hello Joanne,
Congratulations! I'm very happy that you've managed to fix your problem. It's
always essential to understand how to package applications when deploying on BEA
WebLogic. Usually, by throwing everything into an EAR file solves just about all
the class loader problems. :-) Let us know if you have any further problems that
we can assist you with.

Thanks to everyone who gave me help!!!!
The class loader was the culprit which is what I suspected all along.
As soon
as I put the 2 jar files I was using into an EAR file the problem went
away!!!!!
Thanks again

Hello Joanne,
As Mr. Woollen mentioned, I also believe it's a problem with the class
loader.
You need to be careful how you arrange your EJBs, because WebLogic has
a specific
method in which it loads classes in an EAR, JAR, and WAR file(s). Please
refer
to http://dev2dev.bea.com/articles/musser.jsp for more information about
BEA WebLogic
class loading mechanisms and caveats. Also, try printing out the various
methods
that are available on the object that was returned to you via reflection.
For
example, use the getMethods() method, which returns an array of Method
objects
that you can subsequently cycle through and print out the various method
names.
This way you can discover if the class found/returned to you is indeed
the one
you intend to locate.
Hope this helps,

I believe the issue is the home interface class for this EJB is not

If you do:
getClass().getClassLoader().loadClass(homeInterfaceClassName)
I suspect it will fail. Reflection still requires that the class be
loadable.

If I change it slightly and use

Your code should look like

Method homeCreateMethod =
home.getMethod(homeCreate,homeCreateParam);

Hi Ryan,
I also wanted to mention that if you do a "header search" in this
particular
newsgroup
with the search query as "reflection", you will see many previousmessages
regarding
reflection and EJBs. I believe you could learn a lot from thedifficulties
that
others have faced and solved.I tried that and although there was a number of similar cases noneof them
actually
seem to fix my issue. Thanks for the suggestion though
Are the EJBs that you are trying to access accessible via your
system
classpath?
Try to avoid having them accessible via the main system classpath,and
only bundle
them in your appropriate EJB jar files (contained in an EAR file,for
example).Maybe I should have laid the problem out a little clearer.
I have a number of EJB's bundled up in a JAR file which is hot deployedto
the
server. Within this first JAR file is an EJB (SSB) component that
needs
to
be
able to invoke a known method on another EJB. This second EJB may
or
may
not be
within the first JAR file but it also will be hot deployed.
The component trying to invoke the method on the 2nd EJB has to
be
able to
create
an instance of the 2nd EJB without actually knowing anything bar
a
JNDI
Name which
is passed in at runtime.
I can get as far as doing the
Object home = pCtx.lookup(pJNDIName);
This returned a class with the name
"com.csc.edc.projects.allders.httppostoffice.postman.PostmanBean_mp8qy2_Home
Impl_WLStub"
My problem seems to occur when I try and invoke the create method
Method homeCreate = home.getClass().getMethod("create", new Class[0]);
My code throws a java.lang.NoSuchMethodException at this point so
I
am
unable
to progress to the next step of :
Object bean = homeCreate.invoke(home, null);
So I can return the instantiated bean back to the calling client.
Why am I getting the NoSuchMethodException, is is because I am gettinga
stub
back rather than the home interface and if so how do I get the truehome
interface
from the bean
Thanks in advance

Problems with Dynamic Remastering (DRM) with 10.2.0.4 on Linux Itanium

One of my customers is having severe RAC performance issues, which appeared three times so far. Each time, the performance impact lasted around 10 minutes and caused basically a hang of the application. ASH investigation revealed that the time frame of performance issues exactly matches a DRM operation of the biggest segment of the database. During the problematic time period, there are +50 instead of 2-3 active sessions and they are mostly waiting for gc related events: "gc buffer busy","gc cr block busy", "gc cr block 2-way", "gc current block 2-way", "gc current request", "gc current grant busy", etc.
In addition, there is one single session which has wait event "kjbdrmcvtq lmon drm quiesce: ping completion" (on instance 1) and 1-3 sessions with wait event "gc remaster". (on instance 2)
Does anybody have any experience with DRM problems with 10.2.0.4 on Linux Itanium?
I know that it is possible to deactive DRM, but usually it should be beneficial to have it enabled. I could not find any reports of performance impact during DRM operation on metalink. Support is involved but clueless.
Regards,
Martin

Oracle Support has requested stacktraces of lms processes during the period of performance degradation. We decided to enable OSWatcher to get systemwide linux data and procwatcher to get lms process stacktraces. We created a Grid Control User Defined Metric to check whether the symptoms of a DRM performance problem is taking place. Then we triggered the lms stacktraces with a Grid Control Response Action script of the UDM.
Oracle Support has also requested global hanganalyze and system state dumps but we decided not to collect system state dumps because of the big additional performance impact.
The oswatcher data showed that during the drm period, the lms processes had very high CPU resource utilization.
In the meantime Oracle Support has confirmed that we are hitting 6960699. We have received patch 8516675 which includes the bugfix and have installed it. Now, we are waiting to see whether this indeed fixes the issue.

Problem with Dynamic Configuration in SOAP-AXIS adapter..!!!

Hi ,
Idoc> XI>SOAP-AXIS
I am doing a scenario where I need to pass the URL dynamically in SOAP-AXIS adapter by taking the SNDPRN of Idoc.
If SNDPRN = 100 , message has to go to http://10.190.25.16:8210/file/receiver

I have a similar problem. I also like to add some header fields to my message und that's way I'm trying to use the AXIS adapter. (Axis adapter FAQ question 30) Unfortunately I'm getting exactly the same error message:

but thats what you get when a company throws you in at the deep end with a ridiculous time constraint to migrate a whole MSSQL DB.Migrating SQL-Server to Oracle is not a simple thing. A lot of best practices in SQL-Server are absolutely worse practices in Oracle - they are that different. Simple example is lock escalation - an issue in SQL-Server. In Oracle, the concept of a lock being escalated into a page lock simply does not exist.
In terms of getting the migration done as quickly and painlessly as possible I try to reuse all the logic as it appears in the MSSQL code - in this case it was using dynamic table names. I do not doubt that i am probably shooting myself in the foot in the long run.....As long as you do not splatter too much blood on us here.. not a problem :D
Seriously though - just keep in mind that what works in SQL-Server may not work as well (or even at all) in Oracle. So do not hesitate to refactor (from design to code to SQL) mercilessly when you think it is warranted.

Problem with dynamic columns in smartforms.

Dear SDN Experts,
I have a requirement in smartforms for dynamic columns.
i have used template with 10 columns, So from these 10 columns,Columns may vary monthly MIN 2 to MAX 10 depending on
readings with them for that month.
i cannot fix column headings also,Because headings also changes dynamically.
So Problem is if there is no data in columns,Columns is displayng empty.
For EX: In this month i have 2 columns data remaining all columns is displaying empty boxes.
Please suggest me a solution is this posible in smartforms if i use table also.

Hi friend,
See the link below it is having the solution of hiding the columns in smart forms
Hide table columns in smart form?
Create a table to display your values with 12 col and hide the columns based on the idea provided in the link above.

Problems with dynamic PDF display in reader 8.1.0

I have created a dynamic PDF Form having 30 text fields in a row. All these fields are bounded to XSD. The design is like, a row of fields display a single user informations. When I import a XML with 100 user informations, then my PDF crashes. If I import a XML with 50 user informations, then it works fine. Anything beyond that count causes the PDF to close automatically. I believe, its the number of fields which causes the problem. I may be wrong.
I also needs to enter 100 user informations by adding rows one by one. The PDF becomes very slower when I add beyond 35th row. I'm using Livecycle designer 8.0 for designing dynamic PDFs and using Adobe reader 8.1.0 for viewing.
Can anyone help me on this?

Hi,
I figured our there was a setting to enable/disable Javascript which caused this issue.
I was using javascript in the LC 8 for manipulations in the dynamic pdfs.
I enabled the javascript and now it is working fine.

Problem with dynamically created columnchart (FB 4 and 4.5)

I have an application (written in FB4 but I've imported to FB4.5 with no difference in behaviour) which dynamically creates cartesian charts. The total column values should be the same but the user can group them according to different fields. This works fine except for one of the possible grouping options. When that is used, I can see that all the data is present in the dataprovider, but one of the groups is just not shown - or rather when you hover over the column it shows "0" as the value for that group.
This is the code I run when the HTTP query comes back:
private function gotGroupHistory():void{
    if (hsGroupHistory.lastResult.list.item is mx.utils.ObjectProxy) {
        histModelSource = new ArrayCollection;
        histModelSource.addItem(hsGroupHistory.lastResult.list.item);
    } else {
        histModelSource = hsGroupHistory.lastResult.list.item;
    var grouparray:Array=new Array();
    var cset:ColumnSet = new ColumnSet;
    cset.type="stacked";
    var csplan:LineSeries=new LineSeries();
    csplan.displayName="Target";
    csplan.yField="plan";
    for each(var thisitem:String in chartgroups) {
        var cs:ColumnSeries=new ColumnSeries();
        cs.yField=thisitem;
        cs.displayName=thisitem;
        cset.series.push(cs);
        columnchart1.series=[cset];
        columnchart1.series.push(csplan);
        columnchart1.invalidateSeriesStyles();
        columnchart1.series=columnchart1.series;
        legend1.dataProvider=columnchart1;
As I said everything appears to be correct - the data provider has the data for all the groups but just 1 of them is not displayed. The legend also shows the name of the missing group. I really cannot figure out what is going on. Can anyone suggest my next line of investigation please?
Thanks
