Handling multiple exceptions with a single catch block

In the following code:
try{
catch (NumberFormatException a) {
catch (UserDefinedException b) {
The code for both catch blocks are identical. Is there no way I can combine these into one block?
For example, could I not do:
catch ( (NumberFormatException a) || (UserDefinedException b) ){
or anything similar?
I did think of:
try{
try{
catch (NumberFormatException a) {
throw new UserDefinedException("");
catch (UserDefinedException b){
but this just seems to be a waste of code. Any ideas?

I would use the fundamental way to combine identical sections of code--put the code in a new method:
    try {
    catch (NumberFormatException a) {
      myExceptionHandlingMethod(a);
    catch (UserDefinedException b) {
      myExceptionHandlingMethod(b);
private void myExceptionHandlingMethod(Throwable t) {
}

How to handle multiple exception types in JSF 2?

I'm trying to handle multiple exception types in JSF2, including a default error page for any unexpected exception types. The problems I'm having are:
1) ViewExpiredException is handled only when no generic exception handler is specified
2) "Regular" exceptions like NullPointerException are never handled
My managed bean:
@Named
@SessionScoped
public class MyController implements Serializable {
/* A method that does nothing */
public void doNothing() {
    //do nothing
/* Generate a null pointer exception on purpose */
public void generateNpe() throws NullPointerException {
    Object x = null;
    x.toString();
My test page to generate the exception:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core">
<h:head>
    <title>Test page</title>
</h:head>
<h:body>
    <h:form>
        <h:commandButton id="button1" value="do nothing" action="#{myController.doNothing}" />
        <h:commandButton id="button2" value="generate NPE" action="#{myController.generateNpe}" />
    </h:form>
</h:body>
</html>
My web.xml:

<error-page>
    <exception-type>java.lang.NullPointerException</exception-type>
    <location>/error/error003.jsf</location>
</error-page>

<error-page>
    <exception-type>javax.faces.application.ViewExpiredException</exception-type>
    <location>/error/error002.jsf</location>
</error-page>

<error-page>
    <exception-type>java.lang.Exception</exception-type>
    <location>/error/error001.jsf</location>
</error-page>My questions are as follows:
1) How can we handle "regular" java exceptions like NPE?
2) How can we define a catch-all for unexpected exception types, while still respecting specific exception handlers for VEE, etc?
Thanks,
Benjamin

Is your data model right? If you are adding in one and deleting in another it sounds to me more like a process that an entity, in which case you may revisit your data model and simplify it, add in a session bean with the process method to co-ordinate between the two.
However, if you want to map multiple different tables within a single entity bean it is possible and just part of the mapping. How you actualyl specify it depends on which implementation you are working with.

How to handle multiple clients with DatagramSocket

I am trying to handle multiple clients with 1 datagramSocket bind to one port (basically I have only one port to use, and I can not use TCP or any other ports). At the server side I have two threads one for receiving packets and buffering them, another for processing the packets in the buffer and sending replies.
I can have multiple clients sending datagramPackets to me and I will have to process the packets and send them to DIFFERENT clients. Ex. Client 1 sends datagramPacket to Server which sends the processed packet to Client 2. Also Client 2 sends a datagramPacket to Server which again processes the packet and sends it to Client1. May have Client 3 and 4 doing the same thing at the same time... and so on...
My root class is creating the datagramSocket(somePort) and two threads (receiver and sender). How can I use the socket that I created in these two threads??
I have done the following and I am getting "java.net.bindexception". When I am sending stuff from Client1 to Client2 everything is fine but when I start sending something from Client2 to Client 1, I get the bindexception... Client 1 is using port 3000, Client 2 is using port 4000.
I really don't have a lot of experience in socket programming so I am not sure if there is a much simpler way to do this. I appreciate all the tips and help that I can get...
Thanks...

         // not the addresses original packet was sent from.
         try
          op = new DatagramPacket (outPacket, outPacket.length,DA, DP);
          udpSocket.send(op);
         catch (IOException e)
          e.printStackTrace();
}Also for development and testing purposes, I am running the two clients and the server on the same machine (windows xp-32b) so all of the Destination IP Addresses are 127.0.0.1. and as I said Ports that I am using are 2000, 3000, 4000 (Server, Client1, Client2).

Hmm I have minimized the code and it seems to be working now.
I think I have an error in the header portion of the data I am sending, where I am storing the source IP/Port and destination IP/Port. I think the server in the middle is messing these values up while sending them to the destination Client. Because the destination client actually receives the stuff and sends the reply back to the server, but the reply packet's headers has 0/0 as the dest IP / Port...
Server is giving me java.net.BindException: Cannot assign requested address error when it tries to forward the reply it received from the client2 as the address it is trying to send is 0!
I guess it doesnt just give this error when you try to open two sockets to the same port...
Paul, Thanks for the direction on how to proceed... took me a while get the minimized code but at least figured out the problem. Well still have to make sure that is THE problem though :)
As far as the statics goes how can I change those to non static ones? Where do I make an instance of the top level class that creates the threads? and how do I pass the DatagramSocket to the threads/ if I dont need to pass how do I call or use the datagramSocket I created in the top level class? I mean do I still kinda have it like a global variable on the top?? A very simple example would be much appreciated...
I think these might be really basic questions but I am having a rough time with the hierarchy in java...

Handling multiple database with 10g CONSOLE

Hello list,
How do we handle multiple databases with 10g Enterprise Console?
We are running Oracle 10.1.0.2.0 on Windows 2003 server. I have one database setup but I need to install more databases and am having difficulty accessing and managing the second database. thanks for your input.

may be you can try the following:
1) create a file named new_target.xml with the following:
<Target TYPE="oracle_database" NAME="DBAPV9.WORLD" DISPLAY_NAME="DBAPV9">
<Property NAME="OracleHome" VALUE="/opt/oracle/app/oraadm9i/product/9.2.0.4"/>
<Property NAME="UserName" VALUE="sys" ENCRYPTED="FALSE"/>

<Property NAME="MachineName" VALUE="machine.domain"/>
<Property NAME="Port" VALUE="1521"/>
<Property NAME="SID" VALUE="DBAPV9"/>
</Target>
replace as appropriate
2) Execute emctl config agent addtarget new_target.xml
3) Execute emctl stop dbconsole
4) Execute emctl start dbconsole

Select or deselect multiple rows with one single selection event

Does anyone know how to create a JTable which can select or deselect multiple rows with one single selection event in JTable. Fore example, if the table has
row1
row2
row3
row4
row5
row6
What I need is when user select row1 or row2, both row1 and row2 should be set to be selected. Then if user press CTRL and click one of row3 or row4, both of them should be selected including the previouse selected row1 and row2.
For deselection, if row1 and row2 are selected, when users deselect one of row1 or row2, both of them should be deselected.
Hopefully someone can give me a hint.

Here is a partial solution using a JList. Only one line gets highlighted when the user makes a selection in the list. But, two lines are returned. There is a blank line between every two lines.
     private void addLineToList() {
          String a = f_one.getText();
          String b = f_two.getText();
          if (a.length() == 0) {

               f_one.requestFocusInWindow();
               return;
          if (b.length() == 0) {
               Utils.showInformationMessage("Match field is empty.");
               f_two.requestFocusInWindow();
               return;
          model.addElement("item: " + a);

How to handle multiple exceptions by the same code?

Hi, all:
In my situation I want AException and BException handled by the same code, while CException and DException handled by another code. How can I write my try-catch code in a simple way? Of course I can do the following:
public void TheMainFunction() {
    try {
    } catch (AException e) {
        Handle_AB();
    } catch (BException e) {
        Handle_AB();
    } catch (CException e) {
        Handle_CD();
    } catch (DException e) {
        Handle_CD();
private void Handle_AB() {
private void Handle_CD() {
}But is there a simpler way?
Thanks in advance.

If you have one or two places in your code that need multiple exceptions, just do it with multiple catch statements. Unless you are trying to write the most compact Programming 101 homework program, inventing tricks to remove two lines of code is not good use of your time.
If you have multiple catches all over your code it could be a code smell. You may have too much stuff happening inside one try statement. It becomes hard to know what method call throws one of those exceptions, and you end up handling an exception from some else piece of code than what you intended. E.g. you mention NumberFormatException -- only process one user input inside that try/catch so it is easy to see what error message is given if that particular input is gunk. The next step of processing goes inside its own try/catch.
In my case, the ArrayIndexOutOfBoundsException and
NumberFormatException should be handled by the same way.Why?
I don't think I have ever seen an ArrayIndexOutOfBoundsException that didn't indicate a bug in the code. Instead of an AIOOBE perhaps there should be an if statement somewhere that prevents it, or the algorithm logic should prevent it automatically.

Multiple Domains with one single Portal

We have installed Oracle Infrastructure and Oracle Midtier on one box. Let's say the domain name is http://www.abc.com. When we query http://www.abc.com, it
goes to the SSO (Infra) and validates the username and password and takes it back to the Mid-Tier Portal Pages. At this junction, everything is working as expected.
Now, we created two more webpages and they correspond to two domains -- let's say http://www.pqr.com and http://www.xyz.com. The two webpages that got created were PUBLIC pages, so anybody can have access to those pages.
Can we implement our requirements using one infrastructure and one midtier (1st)installation? OR do we install two more midtier (2nd, 3rd) to correspond
to each domain name which are www.pqr.com and www.xyz.com and then have the proxy server redirect the request for www.abc.com to 1st-Midtier, www.pqr.com
to 2nd-Midtier and www.xyz.com to 3rd-Midtier?
We have a apache proxy server installed in front of the 9iAS, but we are going to use it just for redirection.
I understand Oracle Infrastructure has only ONE portal Schema and so how would multiple midtier (webpages) will reside? Do I need to create another PORTAL repository and a new DAD, so that www.pqr.com points to the 2nd-Portal Repository and www.xyz.com points to the 3rd-portal?

Through a single mid-tier it is possible to configure Oracle HTTP Server/Web Cache such that they are configured to handle multiple logical site names (e.g. www.pqr.com and www.xyz.com) by using Virtual Hosts.
In terms of a single Portal Repository being accessed by multiple mid-tiers (or logical sites), this is not currently possible since the Portal Repository is configured with only one set of site details.
For further information on configuring Virtual Hosts and Portal see the Advanced Chapter of the 10g Portal configuration guide...

Replacing multiple spaces with a single space

Hi friends,
I have a string. It can have zero/one/multiple spaces. I want to make the multiple spaces to single space.
Here are the cases:
1. ' a b c d efg h' should be changed to 'a b c d e f g h'
2. ' a b c d e f g h ' should be changed to 'a b c d e f g h'
3. 'a b c d e f g h' should not be changed
4. 'abcdefgh' should not be changed
Both REPLACE and TRANSLATE do not help. I don't want to go for LOOP logic. Please help me to get it in SQL query.
Thanks in advance!

Here are the cases:
1. ' a b c d efg h' should be changed to 'a b c d e f g h'One solution is to post your string on this site, and then copy it back again. (See below for a more serious solution .)
This site is doing exactly what you want the function to do: it replaces multiple consecutive spaces with a single space. As a result, it's hard to see what you mean.
To preserve spacing on this site, type these 6 characters
\(small letters only, inside curly brackets) before and after each section where you want spacing preserved.
2. ' a b c d e f g h ' should be changed to 'a b c d e f g h'
3. 'a b c d e f g h' should not be changed
4. 'abcdefgh' should not be changed
Both REPLACE and TRANSLATE do not help. I don't want to go for LOOP logic. Please help me to get it in SQL query.
Thanks in advance!Regular expressions make this easy:SELECT TRIM ( REGEXP_REPLACE ( str
, ' +'
) AS compressed_str
FROM table_x;
You can use nested REPLACE calls to get the same results, but it's messy.

Handling the ASSIGN_TYPE_CONFLICT in a try catch block

Hi,
Post WAS 610 all system exceptions are handled by exception classes, I could not find the exception class for the runtime exception ASSIGN_TYPE_CONFLICT, if any body is in knowledge of the same or knows of a better way to handle the runtime exception kindly let me know.
Thanks in advance.
Aniruddha Gargya

Hi Raja,
I have already tried all teh exceptions listed for type conversion and assign. The help document also suggested that teh exception class name for a runtime exception will appear in the system trace.
The issue still remains where it was, When i get this execption from a web page the same is not being caught.
Thanks and Regards,

How to insert multiple records with a single query?

Hi,
I've to save a huge number of installments with their other information such as due on blah blah. Now, I want to add the all of these information at once with a single insert query.
How can I do that?

Hi
What is your source data?
If the source is external to the SQL Server (like a log file, Excel, CSV, JSON, XML, external application...) you can and should insert it all using Bulk Insert operation.
Pls clarify what is your source data, and if you need more help using Bulk Insert.

What is the best approach to handle multiple FK with single table.

If two tables are joined with each other with more than one ways, for example
MAIN table is (col1, col2,....coln, person_creator_id, person_modifier_id)
PERSON table is (person_id, name, address,........ phone) etc
At database level PERSON_CREATOR_FK and PERSON_MODIFIER_FK are defined.
Objective is to create a report that shows
col1, col2...coln, person creator name, person modifier name
If above two objects are imported with FKs in a EUL and discoverer plus is used to create above report. On first inclusion of person name discoverer plus will ask you to pick the join (provided the checkbox to disable this feature is not checked). Once you pick 'person creator' join it will never allow you to pick person modifier name.
One solution is two create a custom folder with query like
select col1, col2,...coln,
pc.name, pc.address,.... pc.phone
pm.name, pm.address,.... pm.phone
from main m,
person pc,
person pm
where m.person_id_creator = pc.person_id
and m.person_id_modifier = pm.person_id
Second solution is to import the PERSON folder twice in EUL (optionally named one as perosn_creator and other as person_modifier) and manually define one join per table. i.e. join MAIN with PERSON_CREATOR on person_creator_fk and join MAIN with PERSON_MODIFIER table using person_modifier_fk.
Now discoverer plus will let you drag Name from each person folder without needing to resolve multiple joins.
Question is, what approach is better OR is there a better way?
With solution 1 you will not be able to use functions on folder items.
With solution 2 there is a EUL design overhead of including same object multiple times and then manually defining all join (or deleting unwanted joins), and this could be a problem when you have person_modifier and person_creator in nearly all tables. It could be more complicated if person table is further linked other tables and users want to see that information too. (for instance, if person address is stored in LOCATION table joined with location_id and user want to see both creator address and modifier address....now you will have to create multiple LOCATION folders).
A third solution could be to register a function in discoverer that return person name when person_id is passed. This will work perfectly for above requirement but a down side is the report will run slower if they need filters on person names (then function will be used in where clause). Also, this solution is very specific to above scenario, it will not work if you want the report developer the freedom to pick any attribute from person table (lets say, person table contain 50 attributes then its not a good idea to register 50 functions).
Any comments/suggestion will be appreciated.
thanks

Hi
In a roundabout way you have really answered your own question :-)
In my opinion, the best approach, although by all means not the only approach - see below) would be to have the object loaded as two folders with one join going to the first folder and the second join to the other folder. You would of course name the folders appropriately.
Here's a workflow that I use all of the time and one that I teach when I'm giving Discoverer Administrator training. It might help you:
1. Bring in the PERSON folder to begin with
2. Make all necessary adjustments to bring it up to deployment standard. These adjustments would be: folder name (E.g PERSON_CREATOR), item names, item placement, default positions, default aggregation and so on.
3. Create or assign the required lists of values
4. Create any required calculations
5. Create any required conditions
6. Create the first join from this folder to MAIN.
7. Click on the heading for the folder and press CTRL-C.
8. Click on the heading for the business area and press CTRL-V. A second copy of the folder, complete with all of the adjustments you made earlier will be inserted into the business area.
Note: joins are not copied, everything else is.
9. Rename this folder to say PERSON_MODIFIED
10. Rename the items as appropriate
11. Add a join from this folder to MAIN - you're done
Other ideas that I have used and work well would be to use a database view or create a complex folder. Either will work, In both cases you would need to join on some other column other than the ones you referred earlier.
I hope this helps
Best wishes

How to handle multiple reports with single hyperlink parameter

Please suggest in my drill down report
i have two reports linked with one hyperlink
parameter, how to handle this?
please suggest for popup window with sample solution.
for example
report A--->B--->Chosse Report c or D
based on parameter hyperlink at report B.
Thanks in advance
Raj

Yes U R correct, that
I'm using srw.set_hyperlink in plsql format trigger
to open other reports , now the problem is
how to carry over the hyperlink parameter to popup window
and allow user to choose any reports based on the
parameter value.
for example
report A (Sales person summmary report)
|
| (choose sales person drilled to orders report B)
|
B (report has the hyperlink on order no)
|
|
C,D,E (many reports based on order no
customer,order details,pending items
to be shipped)
Now how to handle the situation from b to c,d,e
I suggest use hyperlink at B to open popup to show
reports C,D,E with the order no has parameter.
please suggest for javascript to open popup window
for reports c,d,e.
Thanks
Raj

How to Handle Dynamic Pivoting with a single SQL?

I was searching for a single SQL who can dynamically understands the pivoting members in the data, I saw several ways of doing Pivoting depending on the version, some are really hard to understand but just two options upto now seams to be flexable enough to do dynamic pivoting, right?
1- For this option you have to write PL/SQL block to build up the dynamic single SQL query, I also find this approach very easy to understand. :)
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::NO::P11_QUESTION_ID:766825833740
2- 11.1 's PIVOT new feature with PIVOT XML and ANY clause, a SINGLE SQL and easy to understand but returns XMLTYPE data, another step to parse to produce the report is needed.
http://www.oracle-developer.net/display.php?id=506
Below is a 10g Model Clause example, but here instead of pivoting by A1-A2-A3 staticly I want to have these values by a distinc subquery for example;
create table test(id varchar2(2), des varchar2(4), t number);
INSERT INTO test values('A','a1',12);
INSERT INTO test values('A','a2',3);
INSERT INTO test values('A','a3',1);
INSERT INTO test values('B','a1',10);
INSERT INTO test values('B','a2',23);
INSERT INTO test values('C','a3',45);
commit;
SELECT * FROM test;
ID DES T
A a1 12
A a2 3
A a3 1
B a1 10
B a2 23
C a3 45

SCCM 2012 Multiple Domains with a single SCCM instance

Hello:
Can SCCM 2012 be deployed to multiple untrusted domains within a single install?
I work for a company that maintains multiple client networks all Windows Domain and non are trusted / or are even aware of the other sites.
I would like to setup a SCCM 2012 (and also a Virtual Machine Manager for HyperV) at my office and manage all my different client sites from the single SCCM server.
The connection would be from my office over the Internet in through their on prem firewall
Currently we use Centra Stage and have used Kaseya in the past. I am looking to move from them and focus on SCCM to do this for me.
Is this even possible to do with the product?
Thanks in Advance!

Yes, ConfigMgr can manage (un)trusted forests, but what exactly do you mean with "not aware of the other sites"? A requirement is that name resolution and a connection is possible.
For some good scenario's see also this series:

How to handle multiple repositories with 11g

Hi all,
this question probably is easy but is right that the only way to manage multiple repositories is to have multiple BIEE 11g installation?
With old 10g with OC4J having multiple installation was quite simple, but here with all weblogic environment is becoming more complex.
I have two branches in my organisation, each one has 3 different environments: test, preproduction and production with a different repository for each one of course.
As I have to meet also High Availabilty requirements I have deployed a two different 2nodes cluster. One cluster has 4 envs and the other one just 2 prods.
All is installed but I still trying to understand or to find a way just to share some resources as for example weblogic server... may a single weblogic installation manage more BI domains?
Thanks
Stefano

Did you ever find a solution to this issue? I come from a BusinessObjects background where you can have as many universes (metadata layers) as you want on your server. I'm trying to figure out a way to replicate that scenario with OBIEE. We have some databases that are so completely unrelated that it doesn't make sense to me to have them all in one big repository, but I don't want to have multiple servers either.
