Steve Muench Chapter 12 error

I'm trying to copy the examples in Steve's book (chapter 12) for multiple table inserts.. page 471.
I created a type
create type dmt_ingred_type as object (
MSDS_NR NUMBER(7),
SEQ_NR VARCHAR2(2),
NIOSH VARCHAR2(9),
PROPRI_IND VARCHAR2(3),
CAS_NO VARCHAR2(11),
INGRED_NAME VARCHAR2(255),
PERCNT VARCHAR2(7),
CALC_PERCNT NUMBER(9,7),
OSHA_PEL VARCHAR2(20),
ACGIH_TLV VARCHAR2(22),
REC_LIMIT VARCHAR2(20),
CARC_IND VARCHAR2(1),
TMP1 VARCHAR2(15),
TMP2 VARCHAR2(5),
TMP3 VARCHAR2(2),
TMP4 VARCHAR2(7),
EXEMPT_IND CHAR(1),
VAPOR_PRESSURE VARCHAR2(10),
VAPOR_PRESSURE_UOM VARCHAR2(5),
VAPOR_TEMP NUMBER(5),
VAPOR_TEMP_UOM CHAR(1),
COMMENTS VARCHAR2(50),
VOC_REACTIVITY_CD VARCHAR2(2),
STATE_POLLUTANT_ID VARCHAR2(10))
I then created another type for the list
create type dmt_ingred_list as table of dmt_ingred_type
I then created the view
create or replace view dmt_msds_xml as select

any ideas??
Thanks

Can you try with the Thin JDBC driver instead of the OCI8 driver?
The error seems related to the OCI8 driver.

Error while running a sample XSQL from XML bible book from Steve Muench

I am running the sample XSQL code from Chapter 03, which deals with exporting XML and transform into SQL statements. I'm using JDeveloper and I believe I've setup libraries and HTML root directory etc. I'm getting the following error:
XSQL-011 Error processing XSLT stylesheet.
XSL-1009 Attribute xsl:version not found in xsl:stylesheet.
Can I get some help in fixing this error?
Thanks a lot,
Murali

Hi,
This is the example I took from Steve Muench's book.
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:template match="/">
</xsl:template1>
</xsl:stylesheet>
As you can see, I do have the version=1.0 attribute. Why is it complaining still?

Thanks,

Thanks Steven.
That makes sense. Is there anything I can do to make this demo work without de-installing 10.1.3.1 Preview? Or If I also install 10.1.3.0.4 with SU5 on another folder, does that affect my 10.1.3.1 Preview version?
I'm using 10.1.3.1 Preview version to learn Oracle's SOA suite.
Thanks again,
Magesh.

Previous to this, I had to include the bc4jhtml.jar file as a library in application.xml, and I've tried using the two bc4jhtml.jar files, but neither one seems to work.
I'm thinking that there must be something simple that I'm missing with the servlet setup...
Thanks!

I tried the wayback machine, but unfortunately, it doesn't cache the SWF files either :( I do have a copy of some (ok one) of Steve's old videos (the one that shows how to do a dropdown list in an editable table, back before it was easy to do), but unfortunately, none of the search ones.

Servlet problem: (Shay Shmeltzer / Steve Muench / Frank Nimphius)

Dear sirs... (Shay Shmeltzer / Steve Muench / Frank Nimphius)
I hope you can give me an answer.
I created an ADF UIX application using JDeveloper 10.1.2. I have created a servlet to download files. my problem is that it works just fine using jdeveloper, while when deployed into oracle application server it causes errors.i am calling this servlet by storing filename and data in the session, then sending redirect request to the browser.
the servlet code is:
package view;
import java.io.OutputStream;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.PrintWriter;
import java.io.IOException;
public class FileDownload extends HttpServlet
public void init(ServletConfig config) throws ServletException
super.init(config);
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
try
String DownloadFileName=(String) request.getSession().getAttribute("downloadfilename");
byte data[]=(byte []) request.getSession().getAttribute("downloadfiledata");
if (DownloadFileName==null)
return;
request.getSession().removeAttribute("downloadfilename");
request.getSession().removeAttribute("downloadfiledata");
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition", "attachment;filename="+DownloadFileName);
response.setContentLength(data.length);
OutputStream OS=response.getOutputStream();
OS.write(data);
catch (Exception e)
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
try
String DownloadFileName=(String) request.getSession().getAttribute("downloadfilename");
byte data[]=(byte []) request.getSession().getAttribute("downloadfiledata");
if (DownloadFileName==null)
return;
request.getSession().removeAttribute("downloadfilename");
request.getSession().removeAttribute("downloadfiledata");
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition", "attachment;filename="+DownloadFileName);
response.setContentLength(data.length);
OutputStream OS=response.getOutputStream();
OS.write(data);
catch (Exception e)
and the error is :
java.lang.IllegalStateException: Response has already been committed
at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.0.2)].server.http.EvermindHttpServletResponse.resetBuffer(EvermindHttpServletResponse.java:1902)
at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.0.2)].server.http.ServletRequestDispatcher.forward(ServletRequestDispatcher.java:213)
this error is stored in the log file. if i am running this code from JDeveloper I can download the files using either FireFox or Internet Explorer without any error.
but if i am running this code using Oracle Application Server 10g Realse 2, i can not download the files using either FireFox or IE.
so i created another solution, instead of redirecting from a datapage into the servlet, i put the following code in a data page as follows:
public void onDownload(DataActionContext ctx)
String DownloadFileName=getfilename();
byte data[]=getdata();
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition", "attachment;filename="+DownloadFileName);
response.setContentLength(data.length);
OutputStream OS=response.getOutputStream();
OS.write(data);
OS.flash();
this time the application works fine when deployed into Oracle Application Server if you use FireFox, but if you use IE, it causes problem, i can not save the file or view it.
what is the problem?
how can i fix this?
i am certin that the second method is not correct and it should not be used.
thanks for everyone in advance
best regards

Dear Sir...
Thanks alot for your replay
regarding the reset method. Itried it and it does not give any good.
I discovered the following problem:
If you are redirecting from with struts dataaction page to the servlet, you get the error
Otherwise if you called the servlet from directly or redirected to a servlet from within a servlet, you get no problem.
can any one help me please??
Is it possible that the problem is in IE itself? The file is downloaded perfectly fine with firefox(but the error log still appear)?
best regards

Issue with Steve Muench's latest eg. How to resolve it?

I have gone through the example "Compelling Dialog" By Steve Muench. Which is available at below link
"http://www.oracle.com/technology/oramag/oracle/10-jul/o40frame.html";
This example is perfectly good even great. There are two issues with this example which i have found and need a solution for those
1. Any LOV or error message that opens from the popup is confined within the pop-up window. Resulting in ugly looks and a tedious way to maneuver. How to work this out?
2. I don't want to give any width or height for this popup. It should adjust as per the required width of the fields.
I have issues with above mentioned two problems. Can any of you come up with the solution of above two problem.
I am working with JDEV11.1.1.2.0 with ADF11g
Thank You in advance

I have had exactly the same problem now with two mini iPads. Everything was tried; 1) restarting; 2) restoring factory settings etc. NONE worked. Eventually Apple agreed to replace it. I have had the replacement now for two to three months and exactly the same thing is happening again. So off to Apple tomorrow to get another replacement.
I am quite a heavy user of the iPad so wonder if this is something to do with the fault.
It is so frustrating as sometimes reset works, and then after 10/20/30/40 minutes (you pick) it goes unstable again.

Dynamic JDBC Credentials: Example 14 from Steve Muench

Hi,
Im trying example from Steve Muench, it's working fine.
But I have some questions about it.
If I want to connect to the db with a wrong username/password I see that it tries 5 times to connect to the database, Where Can I change this number of retries?
Before the password should be used, it must be encrypted. I have two encryption methods, wich one should be used varies.
If the first encryption gives a wrong result(no login) the second encryption should be used.
What is a good place to encrypt the password?
I was thinking of DynamicJDBCSessionCookieFactory because that is called more than 1 time if login fails.

I placed my code to encrypt now in the DynamicJDBCBindingFilter.
This how I try to connect twice
catch (Exception e) {
                    if (isFailedLoginException(e)) {
                        System.out.println("Poging="+poging);
                        attemt+=1;
                        if (attemt<3){
                            FacesContext    fctx = FacesContext.getCurrentInstance();
                            ExternalContext ectx = fctx.getExternalContext();
                            HttpSession session2 = (HttpSession)ectx.getSession(false);
                            if (session2 != null) {
                              session2.invalidate();
                            this.doFilter(request,response,chain);
                        }else{
                            signalFailedLoginAttempt(svrRequest);
                            redirectToLoginPageOnLogonError(request, response);
                    }As you can see I invalidate the session and then I call doFilter again.
This is almost working, but when I'm forwarded to main.jsp with the table I see access denied istead of the table, I also get this error on the Jdev console:
08/03/25 15:09:14 java.lang.IllegalStateException: Session was invalidated

The session is invalidated, but If I don't to that it looks like that the new login credentials are not used. Because then I go back to the login page and see the message that the login\password was not correct.
Someone who knows what I do wrong? I realy need to know this!!

Dynamic JDBC credentials example application from Steve Muench

Apologies for this newbie question...but I'm trying to understand the Dynamic JDBC credentials example application from Steve Muench:
http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html#14
I think I understand most of it but the one bit I dont understand is why it customizes the ADF Page Lifecycle (DynamicJDBCADFPhaseListener, DynamicJDBCPageLifecycle, DynamicJDBCPageLifecycleContext).
Can anyone explain to an ex-forms developer why this code is there?
I'm also trying to work out a way for the session to be invalidated when the user logins again
e.g. a user logins, he doesnt use the logout function but uses the back button to go back to the login page. when he logs in with another set of credentials, would a new session start or as i supsect, it would use the original login credentials?
Thanks

You can ignore those three classes in the example. They are not related to the dynamic credential solution, and must have been left over from some other example I evolved into what you see. Sorry to have cluttered up the implementation with stuff that isn't really contributing to the actual solution. DOH!

For those who used the solution by Steve Muench,Dynamic JDBC Credentials

hi every body
is there any body used the solution by Steve Muench, Dynamic JDBC Credentials .
thanks

Hi,

How can you say ?
Whenever i click any control in the login page i see this message invalid username/passowrd . i do not why i face this problem ?I have tried changing the username,password and database using http://www.oracle.com/technetwork/developer-tools/jdev/dynamicjdbchowto-101755.html which works perfect.

BeginRequest on previously used DataControls (for Oracle guys/Steve Muench)

Hi,
We are using JDeveloper 10g (10.1.2.1.0) and ADF BC+JSP in our application.
In our developer team, in tuning tasks we have detected, that all DataControls that were been used be the user in the past (same session) are activated each request (beginRequest) that user realizes, activated and taking an AM out of the pool and maybe this AM not will be used in this request, and maybe neither in any other future request from the user. Then we have that each AM that were used in the past by the user, must will be activated/passivated if pool is small size limited or pool must will be oversized (server big load situations).
When the user ends using this AM, we call its resetState method, like is recommended by Steve Muench at
Re: application modules and a logoff event (for Steve Muench)
but the next ones user requests will make the ADFBindingFilter call beginRequest on all previous AM anyway. Seems that initially the user BindingContext contains references to DataControls (DCDataControlReference) but when the user uses/gets an DataControl its reference is replaced with the real DataControl instance (DCJboDataControl), and seems that DCJboDataControl.beginRequest, gets an AM instance out of pool, I think that this will make that the AM will not be expired/cleared by the PoolMonitor.
We have hard coded a test in our application that seems to work with the normal ADF and application lifecycle (but I don't like this test too much, too much low level coding), basically the DataControl is replaced by its reference when the user ends using it.
And now the questions. Is it a normal situation? Why we must suppouse that all the AM/DataControl previously used by the user will be used in the current request? There's a normal way to do this, maybe a method that when the DataControl is marked with a flag releases it till the next time user needs it (I'd try release(int) and it didn't works in this way)? Any suggestions/explanations about this?
Comments will be very well received. Thanks in advanced.

Hi Steve,
firstly, thank you very much for your so fast answer.
Ok, I'll open a TAR in metalink. I've searched for the bug# 4566186 in metalink, but I didn't found nothing in metalink for this bug number.

I managed to correct this problem.
The situation is the following:
A CRUD page (Example: userList.jsp and userForm.jsp).
The first page there is a af:table with tableSelectOne and a Edit button. (theres also other components, like af:menuBar and af:form, html, body and head)
On submit, the backing bean(requestScope) gets the selected object (table.getSelectedRowData()), copy the values to the form fields and send (redirect=false) to the form page.
When i try to update, the fileupload does not work and ignores the valueChangeListener. All the other fields are updated correctly.
The form page is used to do Inserts and the upload works correctly.
The problem is, when you redirect (redirect=false) from userList.jsp (usesFileUpload="false")
to the other page, that uses the upload, the form page does not get the enctype="multipart/form-data"
To solve it, put usesUpload="true" in both page , and you will get enctype="multipart/form-data", and upload to work.
Changing components, the af:menuBar has a similar problem.
I got a menubar with 2 goMenuItem.
On each page the corresponding goMenuItem has selected="true".
On redirect, from list page to form page, the selected goMenuItem is the one on the ListaPage, and not the form page! It only changes if I click on the tab I want!
