Problem using multiple contexts in same thread

Hello,
I am having problem using multiple contexts in the same thread. Here is the scenario:
front-end is calling a ejb1 with a user1 and password. Ejb1 is then calling ejb2
using user2 and password. I am getting security exception when calling ejb2 with
the message user1 is not authorized. Looking at the documentation, context 2 should
be pushed on stack on top of context 1 and context 2 should then be used until
context.close() is called. It looks like this is not the case in this scenario?

I have the GTX670. So pretty much the same.
When I go to Edit>Preferences>Playback I see:
When I select the monitor I am not currently using for Premiere Pro, the Program Monitor shows up full size at 1920X1080 in that monitor.
While that may not help you, at least you know a similar card can do the job and you know that it should work.. What happens if you drop down to two monitors? Will it work then?
Also, have you performed the hack that allows Premiere Pro to use the card since that card is not in the file? I have no idea if that is relevant at all, by the way. It is just an attempt at getting our systems to work the same way.

Problem Using Multiple With Statements

I'm having a problem using multiple WITH statements. Oracle seems to be expecting a SELECT statement after the first one. I need two in order to reference stuff from the second one in another query.
Here's my code:
<code>
WITH calculate_terms AS (SELECT robinst_current_term_code,
CASE
WHEN robinst_current_term_code LIKE '%60' THEN robinst_current_term_code - '40'
WHEN robinst_current_term_code LIKE '%20' THEN robinst_current_term_code - '100'
END first_term,
CASE
WHEN robinst_current_term_code LIKE '%60' THEN robinst_current_term_code - '100'
WHEN robinst_current_term_code LIKE '%20' THEN robinst_current_term_code - '160'
END second_term
FROM robinst
WHERE robinst_aidy_code = :aidy)
/*Use terms from calculate_terms to generate attendance periods*/
WITH gen_attn_terms AS
SELECT
CASE
WHEN first_term LIKE '%60' THEN 'Fall '||substr(first_term,0,4)
WHEN first_term LIKE '%20' THEN 'Spring '||substr(first_term,0,4)
END first_attn_period,
CASE
WHEN second_term LIKE '%60' THEN 'Fall '||substr(second_term,0,4)
WHEN second_term LIKE '%20' THEN 'Spring '||substr(second_term,0,4)
END second_attn_period
FROM calculate_terms
SELECT *
FROM gen_attn_terms
<code>
I get ORA-00928: missing SELECT keyword error. What could be the problem?

You can just separate them with a comma:
WITH calculate_terms AS (SELECT robinst_current_term_code,
CASE
WHEN robinst_current_term_code LIKE '%60' THEN robinst_current_term_code - '40'
WHEN robinst_current_term_code LIKE '%20' THEN robinst_current_term_code - '100'
END first_term,
CASE
WHEN robinst_current_term_code LIKE '%60' THEN robinst_current_term_code - '100'
WHEN robinst_current_term_code LIKE '%20' THEN robinst_current_term_code - '160'
END second_term
FROM robinst
WHERE robinst_aidy_code = :aidy),
/*Use terms from calculate_terms to generate attendance periods*/
gen_attn_terms AS
SELECT
CASE
WHEN first_term LIKE '%60' THEN 'Fall '||substr(first_term,0,4)
WHEN first_term LIKE '%20' THEN 'Spring '||substr(first_term,0,4)
END first_attn_period,
CASE
WHEN second_term LIKE '%60' THEN 'Fall '||substr(second_term,0,4)
WHEN second_term LIKE '%20' THEN 'Spring '||substr(second_term,0,4)
END second_attn_period
FROM calculate_terms

BC4J Problem using multiple EntityObjects in a single ViewObject

Hi,
I have found a bug while using multiple EntityObjects in a single ViewObject.
Considere the following example:
Table A:
A_ID
Table B:
B_ID
A_ID (FK) NULLABLE
TABLE C:
C_ID
B_ID (FK) NULLABLE
For each table there is a corresponding EntityObject : AEntity, BEntity and CEntity.
Now building a ViewObject based on CEntity, BEntity and AEntity, where AEntity and BEntity are referenced via their corresponding associtaions, the following problem occurs:
1. As long as both IDs are not NULL everything works fine, but when I set the B_ID attribute of CEntity to NULL I receive a NullPointerException with the detail "null".
2. If the attribute A_ID of BEntity is NULL the values based on AEntity are not updated at all (they keep the value they had for the last row).
Any information or feedback on this issue would be very welcome!
Regards
Frank

Here's a sample code that works for a
LineItem->OrdView->CustomerView case,
public void setOrdId(Number value)
    //set the boolean if there's a current order.
    boolean hasOrd = (getEntity(1) != null);
    setAttributeInternal(ORDID, value);
    //after the OrdID is set, check if there's a valid Ord Entity in this row.
    if (hasOrd && getEntity(1) == null)
      //if not, then set the Customer Entity to null as well.
      super.setEntity(2, null);
      LinesViewImpl vo = (LinesViewImpl)getViewObject();
      //And force a RowUpdated event for "customer-entity-usage-attributes".
      vo.notifyRowUpdated(findRowSetForRow(null), new oracle.jbo.Row[] {this}, new int[]{6,7});
} Note that in the above, you have to "override" notifyRowUpdated method in the ViewObjectImpl subclass, so that it's available to the LineViewRowImpl subclass. You can do this
globally by creating a custom subclass of ViewObjectImpl that all the VOs in your application "extends".

Problems using multiple joins for search

I am new to dreamweaver and coding and I am battling to get my head around joining tables and using multiple joins to create a search result recordset.
I have a the following tables setup;
Venues table
venueID
name
category (text)
city
provinceID (numeric)
country
maxcapacity
Province table
provinceID
province (text)
Category Table
categoryID
category (text)
Max Conference Table
conferencefacilitiesID
venueID
maxcapacity
I am passing the search $_POST variables via a form and displaying it in a results page.
I have successfully done the search using only one table the problem results in using multiple joins. I cam not sure of the syntax to use but have successfully created the results page, using the outer join to link the province, category and maxcapacity to the venues table. Not all the venues have conferencing so I think need to use outer join for conferencing.
I can't seem to access the search and not sure if I can use the WHERE command to set varialbe 'category' = varCategory
Below is my code which doesn't work;
SELECT wp_dbt_venues.venuesID, wp_dbt_venues.name, wp_dbt_venues.category, wp_dbt_venues.province, wp_dbt_venues.city, wp_dbt_province.provinceID, wp_dbt_province.province, wp_dbt_conferencefacilties.venueid, wp_dbt_conferencefacilties.maxcapacity
FROM ((wp_dbt_venues LEFT OUTER JOIN wp_dbt_province ON wp_dbt_venues.province = wp_dbt_province.provinceID) LEFT OUTER JOIN wp_dbt_conferencefacilties ON wp_dbt_venues.venuesID = wp_dbt_conferencefacilties.venueid)
WHERE 'category'=varCategory
I would like to get on variable working and then expand onto the others like WHERE maxcapacity < varCapacity

Hi bregent
Thank you for all the help, below is the code. I have clened it up as best I could as dreamweaver seems to add recordset everytime I edit it. I then have to delete the old code. It also seems adds a totalRows variable and moves one of the runtime variables to the totalRows variable. Its all very confusing but its working.

ASDM_HANDLER problem on multiple context mode

Hello,
Has any anybody seen this error?
On the firewall multiple context I used to jump from one context to another, but now when I log in to the admin context and I try to jump to another context I receive this error. Could no find any bug on release notes for that.

Hi,
I have not personally seen this error before. Though I don't use ASDM that much anyway. We used to have FWSMs in multiple context mode and now have ASAs running multiple context mode and I have never seen this.
Have you checked the situation (as the error message suggests) from the CLI of the ASA to see if there is a lot of ASDM sessions in the "admin" context of the unit?

Problem with Multiple Context Creation

Hi,
We are facing a java.lang.SecurityException Invalid Subject
We need to create multiple Initial Contexts for a single thread.
Following is the Scenario
1) The user will access Servlet/Struts Action class which performs database call and EJB(one, two) calls with different Initial Contexts ( Credentials are different)
2) At the same time the Timer Task runs in back ground which is invoked from servlet load-on-startup and runs for every 1 min.
3) The Timer Task invoke an MDB this MBD will make an external EJB (three) call for business logic.
{color:#ff0000}Please Suggest me the Sequence of step I am expecting are correct or not{color}
1) The Timer Task will run in the same JVM where the Servlet/Action classes are loaded (WEB-CONTAINER)
2) The Thread created for Servlet/Action class will not be shared by Timer Task.
3) The Thread created for Timer Task and the MDB are different.
4) So the Servlet - Thread, Timer Task Thread and MDB Thread are different.
The Behavior of the Context is as follows according to Bea Document.
[http://e-docs.bea.com/wls/docs81/jndi/jndi.html#476864]
JNDI Contexts and Threads
How to Avoid Potential JNDI Context Problems (Please Refer this Paragraph)
I am closing the entire Context's immediately after lookup
Still we are facing this java.lang.SecurityException Invalid Subject Exception Problem
The Context of EJB which we are calling from MDB is sharing the Servlet/Action Class Context -- Credentials
Example_
{color:#ff0000}Servlet/Action Class Context Credentials -- are user1/pass1{color}
{color:#ff0000}EJB (three) Context Credentials -- are user3/pass3{color}
When EJB (Three) lookup is invoked it’s throwing the following Exception
*java.lang.SecurityException: [Security: 090398] Invalid Subject: user1*
Please advise to solve this problem
Thank You.

Problem using multiple Client Certificates

Hi folks, I had (mistakenly) posted an earlier version of this question to the crypto forum.
My problem is that I have multiple client certs in my keystore, but only one is being used as the selected certificate for client authentication for all connection�s. So, one connection works fine, the rest fail because the server doesn�t like the client cert being presented.
I have been trying to get the JSSE to select the proper client certificate by making use of the chooseClientAlias method. (init the SSL context with a custom key manager that extends X509ExtendedKeyManager and implements the inherited abstract method X509KeyManager.chooseClientAlias(String[], Principal[], Socket))
But, still no luck.. the JSSE is not calling in to the my version of chooseClientAlias, and it just keeps presenting the same client certificate.
No clue why, any thoughts on how to get the JSSE to call my version of chooseClientAlias?
Thanks!
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(createCustomKeyManagers(Keystore, KeystorePassword),
            createCustomTrustManagers(Keystore, KeystorePassword),null);
SSLSocketFactory factory = sslContext.getSocketFactory();
URL url = new URL(urlString);
URLConnection conn = url.openConnection();
urlConn = (HttpsURLConnection) conn;
urlConn.setSSLSocketFactory(factory);
BufferedReader rd = new BufferedReader(new InputStreamReader(urlConn.getInputStream()));
String line;
while ((line = rd.readLine()) != null) {
     System.out.println(line); }
public class CustomKeyManager extends X509ExtendedKeyManager
    private X509ExtendedKeyManager defaultKeyManager;
    private Properties serverMap;
    public String chooseClientAlias(String[] keyType, Principal[] issuers, Socket socket)
        SocketAddress socketAddress = socket.getRemoteSocketAddress();
        String hostName = ((InetSocketAddress)socketAddress).getHostName().toUpperCase();
        String alias = null;
        if(serverMap.containsKey(hostName)){
            alias = serverMap.getProperty(hostName.toUpperCase());
            if(alias != null && alias.length() ==0){
                alias = null; }
        else {
            alias = defaultKeyManager.chooseClientAlias(keyType, issuers, socket);
        return alias;
.

Topic was correctly answered by ejp in the crypto forum..
namely: javax.net.ssl.X509KeyManager.chooseClientAlias() is called if there was an incoming CertificateRequest, according to the JSSE source code. If there's an SSLEngine it calls javax.net.ssl.X509ExtendedKeyManager.chooseEngineClientAlias() instead.*
You can create your own SSLContext with your own X509KeyManager, get its socketFactory, and set that as the socket factory for HttpsURLConnection.*

Help! Using multiple ipods on same account - for education

Hi, I'm a primary school teacher and have just purchased 5 ipods to use with Year 2 students in the classroom. Is there any way of syncing the songs and/or short movies to all 5 ipods? I don't mind paying for these things once but not 5 times each time I need a little video! Please help me...the kiddies are aching to use them!
Thanks,
Bree

No problem... you can sync the same data, including purchased media, to multiple iPods. The 5-computer limit applies to the number of computers you can authorise to play your tracks, not the iPods they can be played on.

Chart creation using multiple series with same name

I'm new to Numbers and to chart creation in general, so I'm not sure if Numbers is capable of what I need. But if so, I'd like to know how...
I have a large spreadsheet with hundreds of lines of expense data, wherein each line item falls into one of a dozen categories of expense types. I would like to create a pie chart by expense type (ie, Healthcare, Automotive, Travel, etc), but Numbers wants to treat each line item as a separate expense, even though many of them share the same name. So I'm getting multiple pie slices that all say "Travel" and so forth. I really just want one pie slice for Travel, one for Auto, etc.
So how can I make Numbers calculate the subtotals for each expense type and use those subtotals to create the chart? Is there a way to do this within the chart function or do I need to create a separate table for just the subtotals (not sure how to do that either) or what?
Thanks!

It appears that I missed your question.
Here is a way to treat the problem:

Ethernet Problem with Multiple users on same Mac

Hi, sorry i advance for my english. I am writing from italy.
I have an imAc with 2 users profiles on it. one profile is administratoe, and the oter a standard user.
I also have a time capsule configured to connect to my network with the ethernet cable. the cable is plugged in the wan pot, the configuration is "bridged" and i use as a router a linksys wifi router.
well. suppsung that i am logging in with one of my users and access to time capsule wirelessly, it shows me the disk content.
i then swith to the other user without logging off the first one and then access time capsule where i see the same folfder and i can access it. so everything works fine.
in the case i connect my mac with ethernet (disabling airort) to my linksys router, ifuser 1mounts time capsule, user 2 can't access it if user 1 does not unmount.
why so?
i need to switch from user 1 to user 2 without logging off, and i don't understand why it works wirless and not with ethernet..

In fact, all my page beans are in REQUEST scope...
The only bean in Application scope is the standard applicationBean created by Creator itself.
We use one Bean in session scope which contains another class.
I will try to explain our common process:
- when logging into the app, the session Bean stores user data (rights for using app,...);
- when navigating in the app, the user can search data, modify them and create one (if he has the right to do it);
- to define the screen, we use a lot the beforeRenderResponse();
- when viewing a data, the user can choose to modify it, so depending on the action, the page is in "CONSULT" mode or "MODIFY" mode. In the second one, he can display new gridPanel (as a subform) to populate datatable.
The problem is obvious while using this grid: my grid can disappear if someone else has validated his form before me and if my page goes trough the beforeRender of my page.
It is not really clear. If needed, i can give access to our application to show the problem (and msn adress too to talk about it).
Thank you

Urgent - problem with multiple users on same page

Hi all,
I have got an big problem with my app:
when several users are using the same page, the action launched by USER_A affects the page displayed and used for USER_B.
If there is only one user using the page, there is no problem at all.
The webapp is deployed on Tomcat or JBoss and the problem remains the same on both.
Thank you for your help.

Problem using multiple collections in web gallery

I have a web gallery in LR5 that I created in LR2. It consists of four collections with individual titles. When I try to include the titles using the right-hand panel in the web module, when I change the title of one collection, all four collection titles change to that title. I can't give the collections individual titles. I'm using Mountain Lion on an iMac. I didn't have this problem in LR2 and LR3 but I have ever since I upgraded to LR5. Am I doing something wrong?

Hi,
APEX_COLLECTIONS are special structures that do not have indexes, expect for the one on SEQ_ID. The result is that as the number of collections used in a query increases the number of full table scans on underlying tables kill speed. They are not intended for such heavy use as has been discussed in some of the threads in this forum.
They are extremely useful , but no good for very large data sets or large number of joins. Global temporary tables are also not an option with Apex.
You may have to resort to Materialized Views or intermediate/temp tables to get speed.
Regards,

Problem ::
In above example, I am showing datagrid where column "Col1" having multiple item renderers. On change of checkbox from "Sent" column, I am dynamically displaying either of the item renderers. i.e., if checkbox is false then datefield else textinput field.
But when I type in text in textinput, then after outfocus still it displays that textinput in the datagrid cell. I want it to display only label in that cell.i want Same behaviour just like editable column when chkbox is select. and default show renderer in datagrid.
Thanks,
Amol

If you want to show a label, add a label to the renderer or convert your
renderer to an itemEditor

works ??

Hi there,
I don't really understand what you're doing but I used lot of LOV in custom attributes on my custom items and everything works fine.
Can you explain more your problem ?
