How to override the default delete operation

Hi,
I am new to Jheadstart, java coding for that matter.
Here's my situation,
I have a view which is based on a function (function returns a collection).
I have created instead of triggers on this view to perform insert/update/delete operations.
All these DML operations work as expected in Oracle database.
Now, I created an Entity object and a view object on this view in my jheadstart project.
When I run this Jheadstart application my insert and search operations run fine but update and delete operations fail with JBO-26080 error.
The underlying oracle error is "ORA-02014: cannot select FOR UPDATE from view with DISTINCT, GROUP BY, etc."
I know that delete and update operations work fine in Oracle and hence I would like to override the default Jheadstart operations. Can any body tell me how can I do it or point me in right direction?

Hi,
From the JHeadstart Developer's Guide, chapter TroubleShooting - Problem Assessment:
If you are getting a JBO error (Business Components for Java error), try to perform the same data retrieval or data manipulation action using the BC4J Tester. You can
invoke the tester through a right-mouse-click on the BC4J application module. If you get the same error using the BC4J tester, the problem is in the BC4J object definitions. If you added business rules, or other custom code to your BC4J objects that executes during your data retrieval or data manipulation action, you can debug this code line-by-line by running the tester in debug mode. You can also look up the JBO error in the JDeveloper online help, for each error possible causes and how to solve them are described.
It sounds to me like you will also get this error in the BC4J Tester. This means that the problem is not related to JHeadstart. You can go to the JDeveloper discussion forum http://otn.oracle.com/discussionforums/jdev.html and ask your question there without mentioning JHeadstart. Maybe there is some switch you can set in the BC4J object to let BC4J not use SELECT FOR UPDATE.
Hope this helps,

How to override the default order UOM when using BAPI_PO_CREATE1...

Hello Experts,
How do I force BAPI BAPI_PO_CREATE1 to use my declared purchase order unit of measurement instead
of getting it in the material master data? For example, material A has a default purchase UOM of CV, but
when I create a PO using material A I want the purchase UOM to be EA instead of the default CV.
How do I do that?

How to override the default "required" attribute for the UIComponent?

Hi, consider the following markup: <h:inputText id="txt_firstName" value="#{myBean.firstName}" required="true"/>
if I leave this field empty and hit the submit button, the required validator will fire an error msg. If however, I leave an empty space in the text box and hit submit button, it will go through no problem.
I'd like to override the required attribute, so it will trim the spaces first before decide if it really is empty:
//whatever the name of the method i'm overriding....
String value = (String)value;
if(value==null)throw new ValidatorException(whateverDefinedInTheBundle);
value = value.trim();
if(value.length==0)throw new ValidatorException(whateverDefinedInTheBundle);
How can I go about doing that?
Thank you.

JRE 1.4.2: how to override the default xml parser?

Hi all,
I have JRE 1.4.2_03 and I need to replace the default xml "crimson" parser with xerces because the former one doesn't properly handle utf-8 BOM.
Does anyone have an idea where I should look at for this kind of configuration?
I skimmed thorugh the oracle docs but couldn't find anything.
I found a link describing how to change the xml parser in OC4J, but my understanding is that this has little to do with what I am looking for.
I need to force Saxon 8.6.1, that is invoked by means of java.exe from the command line, to pick up the right xml parser.
Has anyone else tried this out already?
Alternatively, is it safe to install JRE 1.5 in place of JRE 1.4.2 on a Oracle 10.1.0.4 database?
I am told that JRE 1.5 uses a different xml parser that should fix my problem.
Bye,
Flavio

I sorted this out myself.
Downloaded the latest stable xerces binary (2.5.0) from http://xml.apache.org/dist/xerces-j/
Then I extracted xercesImpl.jar and put it under:
%ORACLE_HOME%\LIB\endorsed
I had to create the endorsed folder as it didn't exist.
Then, when invoking Saxon using java.exe, I added the following switch:
-Djava.endorsed.dirs=%ORACLE_HOME%\LIB\endorsed
That's it.
You can find some background info on:
https://jaxp.dev.java.net/Updating.html

How to make the default shutdown operation to be a forced one?

Just recently I clicked on shut down and went with my business, only to find out on return that OS X didn't shutdown the laptopt because "firefox prevented" it from doing so. What a BS.
Is there a way to change the default parameters for the shutdown execution?

No.
You could go into the Terminal and use the "sudo shutdown -h now"

HT201448 How to override the default order of Websites, Wiki, and Xcode services?

Greetings,
On my Mac server, I have the Websites, Wiki, and Xcode services all enabled but, as detailed by the Apple support article, Xcode takes precedence over all, or Wiki if Xcode is disabled.
What I would like to see is a virtual host (e.g. wiki.myhost.com) and/or directory alias (www.mydomain.com/xcode) that opens the home page for the respective service while the default (e.g. www.mydomain.com) goes to the home page for mydomain.com.
I'm no httpd configuration expert but I expect some manual httpd configuration will be required. Any help appreciated.

At the end, I decided to adopt Firefox add-on "Classic Theme Restore"—amazing output. I guess it is impossible to get such a space saving but full furnished solution somehow else.

How to override the 'default' partition in composite.xml - urgent

All,
Version: 11.1.1.4
I have created a simple BPEL A which invokes another BPEL B which is deployed to 'default' partition. In the composite.xml of BPEL A I can see the WSDL location of BPEL B as *"http://localhost:7001/soa-infra/services/default/BPELB/BPELB.wsdl"*. I noticed that the name of the partition (i.e in our case its 'default') is hardcoded in the wsdl location. During deployment I want to override to other partition, how I can achieve this?
thanks

If you want to change the partion name at run time then used Token ,value concept and define it in build.xml
For Example
<target name="replaceAllValues">
<input
message="Please enter full path of the file directory:"
addproperty="dirPath"/>
<replace dir="${dirPath}">
<replacefilter
token="OldValue."
value="Newvalue"/>
</replace>
</target>
Call the above target from ant build.xml before you deploying the service.

Tarak.

How to override the default SOAP envelope prefix?

I have a Web service as an external reference. In run-time WebLogic generates SOAP messages with a default prefix <env:Envelope xmlns:env=http://schemas.xmlsoap.org/soap/envelope/”…>. Normally this is fine. However the Web service required a prefix as <soapenv:…>. How can I have WebLogic generate soap envelope prefix as soapenv instead env?

hello!
It's possible. You must implement handler and change envelope and body prefix. Here is example:
public class WsHandler implements SOAPHandler<SOAPMessageContext> {
public boolean handleMessage(SOAPMessageContext context) {
Boolean outboundProperty =
(Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
if (outboundProperty.booleanValue()) {
try {
SOAPEnvelope envelope = context.getMessage().getSOAPPart().getEnvelope();
envelope.setPrefix("soapenv");
envelope.removeNamespaceDeclaration("env"); //remove old prefix
envelope.getBody().setPrefix("soapenv");
context.getMessage().saveChanges();
} catch (Exception e) {
throw new ProtocolException(e);
}

How to change the default operators in sap web ui Search screen?

How to change the default operators in sap web ui Search screen?
For eg. Using advance search option , I have some fields with default operators like equals, contains,is between, is less than and is greater than. I don't need all these operators for this field.
I need only "equals" operator. How do i remove the rest of the operators?

There is a view cluster crmvc_dq where all the standard setting is present related to you r issue. Please try if you can modify that, that way you will avoid the code.
Incase you are not able to make any changes there then in that case you have to redefine the method GET_DQUERY_DEFINITION () of the IMPL class to delete the operators for a particular serach field.

Clarification:
I believe now you potentially lose all extensions, plug-ins when you use the new reset function, but you will let me know.
If that is the case, your find corrupt file method maybe better. However, I reviewed the two help articles and there appear to be more files than just the delete search.json file and a possible search.sqlite file in the Firefox Profile Folder. I am confused. Then I have to find the folders. I think help articles mentioned how to find the profile containing the files, but not sure.
