Need help implementing AJAX in an existing Struts Application

Hi!
I am trying to implement AJAX in my existing Struts Application. I need a good approach to go ahead and implement Ajax. I was thinking.. may be i will have to club all the code in the forms n actions (in the current Struts application) to one form and action, So I can easily include the dynamic content in the page.
Please let me know if you have any ideas of how to implement AJAX in a fully developed Struts application.
Thanks,
Swapna.

Need help on AJAX in java

Hi! I'm very new to the concept of AJAX and I was hoping someone could help me out. Basically, I have an application that needs to implement AJAX to speed up the transaction.
What the program does is it has a dropdown box which has dates. After the user selects a date and clicks the submit button, the server returns a user from the database.
My question is, how do I implement AJAX here? If it is possible, please guide me with this since I barely know how and where to start.
Thanks!

Integrating an existing struts application

Sorry if this has been discussed before but I tried searching the newsgroup with
no success. tia.
I am trying to integrate the struts application found in the struts-example.war
file that I extracted from the jakarta-struts-1.1.zip file from jakarta.apache.org.
(I have successfully deployed and tested this war file to the weblogic server
so I know the application works.)
I unzip the war file into a temp directory and follow the instructions found in
"e-docs.bea.com/workshop/docs81/doc/en/portal/buildportals/appIntegratingStruts.html"
After creating a struts portlet using the wizard and putting the portlet into
my test portal, when I try to run the portal using debug in Workshop, I get:

Help would be greatly appreciated. tia.

Have anyone got the answer from BEA ...
I am also having the same problem.
Pl. post if you have any answers.

Hi,
I have the same problem and I can't find any way for correcting this.
Please, help-us with this issue because integration of existing Struts
applications
into a portlet is a critical issue for choosing a Portal solution.

Hello,
Did you copy the 2 JAR files in your /forms/java directory ?
Did you add them to your /forms/server/formsweb.cfg file (archive_jini tag) ?
As always when a Java Bean is in the game, display the Java Console at runtime to see if any error are raised.

Need help from Jeff in getting CC desktop application

Jeff, I was unable to find my previous question to you from the other day. To start over, my CC desktop application is gone missing after 10 months of CC usage. I need to download a LR update so I can use my camera with raw files. How can I get this back? Apparently Adobe doesn't allow reinstalling of individual programs even though I actually own LR. Please redirect me accordingly. I need help. I have win 7 64.

Need help Installing OID Repository on existing database server using RepCA

I have an oracle database server running 10g (10.2.0.4) and I want to install metadata repository on it. I downloaded the Application Server Metadata Repository Creation Assistant 10.1.2.0.1 (standard edition).
I find that there are no batch files in the download, just setup.exe. When I run that I am asked for an ORA_HOME - when I provide the home where the database is installed I get the message that the home already has the database and the software cannot be installed on it.
How do I add the repository to an existing instance of oracle database server? Also, is the version I downloaded the right version #
Thanks

Hi sameer khan,
first let me ask, are you talking about Netweaver04s (WAS 7.00), in this case my answer can give you some hints.
Note 883948 gives information of the installation of an additional usage tye (like BI JAVA)
You have more than one possibility to install the usage type BI JAVA. The most common installation types are:
1. BI installation and a separate BI JAVA installation with 2 <SID>
2. BI JAVA Addin Installation in an existing NW04s
I recommend to use option 1:
In case you install a separate BI-JAVA instance, you need a separate <SID> for your J2EE environment. In this case it is not possible to use the same <SID>. This installation can be done on the same or a separate server. Furthermore, you can use a separate database or install the J2EE instance in the same database (--> MCOD). I recommend to use a separate database. Note: In this installation option, Sapinst normally installs a separate user store. With the usage type BI JAVA it makes (in most cases) sense, to use the user store of the BI system, where it belongs to. If you want to do so, "Revise" the user store option before you start the installation and and choose the production client of the BI system.
If you like to use an Addin Installation, another <SID> is not possible. I would only recommend this kind of installation in test environments.
It doesn't matter, which kind you choose, after installation, you have to do the steps for "Setting up bex Web", see Note 917950. This is sometimes a little bit tricky, with Note 937697 there is a Support Tool, which can help.
Good luck with your installation
Kind Regards

ACE - need help implementing basic parameter map

Hi,
I'm trying to implement a connection parameter on an ACE module that sumply sets the TCP timeout to 0.
I can get this to work fine if I permit all TCP traffic in the class-map, but it doesn't work if I use an ACL;
>>Match all TCP;
parameter-map type connection TCP-Timeout
set timeout inactivity 0
class-map match-all TCP-Timeout-Out-Class
2 match port tcp any
class-map match-all TCP-Timeout-in-Class
2 match port tcp any

Any ideas?
Many Thanks

Try changing the class-map from "type match-all" to "type match-any". Match all implies both statments need to be true. The match-any is probably what you want. Either of the ACL statements can be true.
Also try to apply the policy globally instead of the interfaces, simplifying the config might help as well.
e.g.:
access-list TCP-Timeout-Group line 10 extended permit ip 10.221.178.0 0.0.0.255 any
access-list TCP-Timeout-Group line 20 extended permit ip any 10.221.178.0 0.0.0.255
class-map match-any TCP-Timeout-Class
match access-list TCP-Timeout-Group
parameter-map type connection TCP-Parameter-Map
set timeout inactivity 0
policy-map multi-match TCP-Timeout-Out-Policy
class TCP-Timeout-Out-Class
connection advanced-options TCP-Parameter-Map
service policy input TCP-Timeout-Out-Policy <- apply it globally
Hope it helps.

Need Help Adding Flash Intro To Existing Site

OK I'm helping a buddy of mine out and he's already got his sie built for him by someone else, the index file is .php. Now I've got this little Flash animation that we want to run first, then when it's done go to his website. When I try to add it to the top of the index page all that happens is the site loads like in normally did but with the Flash movie at the top instead of being another page. What do we need to do to have it load on it's own first?

yes. the index.html should embed your flash intro swf and at the end to your swf (and in a skip intro button code) you should open the current main page (using getURL or navigateToURL).

Need help, implementing streams between oracle 10g databases

Hello all.
Please help me, and give me instruction if any body implement streams between databases (Oracle 10g)
I have implemented streams between schema table on (10g) and result was success.
Firstly I want to know some thing, such as:
1) Is it possible make streams with conditions, (make only DML or DDL i know) but make DML and not DELETE operation, just INSERT and UPDATE operations on the table?
2) After changes was applied on target database, can I delete that records which copied (replicated) on source database?
I have 2 databases and one of them is for archive purpose (I want use it as target database for streams). Other one is PROD database, applications make DML operation.
I) record insert with null status
II) processing (status 1)
III) if success (status 2) unsuccess (status 3)
For now, I have cron script on (Linux host) and in this script has PLSQL anonymous block and it works couple times during the day. This script works as archive.
My task is: Make it via Oracle streams.
Thank you beforehand.

For conditions on the type of operation (Insert) check in the doc after apply handler and you can associate what ever code and conditions you want. You can also choose to work with a subset rules but there are some restriction as no lobs :

Need help implementing Radix sort to handle negative values

Hi !
I'm in desperate need for some help here...
I've been struggling with this Radix sort algorithm for some time now. It sorts positive integers very well, and very fast, but it cant handle negative values. Is there anyone who can help me improve this algorithm to also sort negative integer values?
I need it to be as fast or even faster then the current one, and it has to be able to sort values in an array from address x -> y.
Here's what I have so far
/** sorts an int array using RadixSort (can only handle positive values [0 , 2^31-1])
      * @param a an array to be sorted
      * @param b an array of the same size as a (a.length) to be used for temporary storage
      * @param start start position in a (included)
      * @param stop stop position in a (excluded)
     public void sort(int[] a, int[] b, int start, int stop){
          int[] b_orig = b;
          int rshift = 0, bits = 8;
          for (int mask = ~(-1 << bits); mask != 0; mask <<= bits, rshift += bits) {
               int[] cntarray = null;
               try{cntarray = new int[1 << bits];}catch(Exception e){System.out.println("Error");};
               for (int p = start; p < stop; ++p) {
                    int key = (a[p] & mask) >> rshift;
                    ++cntarray[key];
               for (int i = 1; i < cntarray.length; ++i)
                    cntarray[i] += cntarray[i-1];
               for (int p = stop-1; p >= start; --p) {
                    int key = (a[p] & mask) >> rshift;
                    --cntarray[key];
                    b[cntarray[key]+start] = a[p];
               int[] temp = b; b = a; a = temp;
          if (a == b_orig)
               System.arraycopy(a, start, b, start, stop-start);
     }I think it can be solved by offsetting all positive values the with the number of negative values found in "a" during the last run through the main for loop (as the last (or first) 8 bits in an 32 bit integer contains the prefix bit (first bit in an 32 bit integer), 0 for positive value, 1 for negative).
Thanks in advance !

Need help implementing a Questionnaire page

Hi,
I have a requirement to build a web page which is like a Questionnaire page.
There are multiple questions and each question can have multiple acceptable responses. The responses can be either an Input text/Check box/RadioGroup depending on the Question type.
Each question can also have sub-questions depending on the responses. Each sub-question will also have its acceptable responses and further child questions. Currently we are supporting 5 level of parent-child questions hierarchy.
We are also planning to support the re-arrangement of questions. Is it possible to achieve this functionality using standard ADF components ? I am trying to implement the same using a Tree table. I created a self reference view link to display all the questions in a hierarchal manner. But for displaying the responses I was not able to define the relationship in the tree table.
The same thing I tried with forEach. Defined view links between Questions and responses VO. But I guess forEach does not support view links. So I was not able to get the responses corresponding to each question.
[UI Mockup|http://apps-ux.us.oracle.com/fusion_prototypes/v2/prc/PRC_Qualification/shells/questionnaire.htm] for this page.
Please suggest some approach to implement the above functionality.
Thanks in Advance,
Rakesh

The Questionnaire page will look somewhat like the below questions.
1.How long has your company been in business? //Parent question#1 : There are 3 radio group for selecting A/B/C.
A.○ 0-2 years
B.○ 3-5 years
C.○ 5-10 years
1.A.1 What is the founding month & year of your company? // For response A there are two sub-questions 1.A.1 & 1.A.2, 1.A.1 is of type I/p text & 1.A.2 shows 3 checkboxes.
1.A.2 Who are some of your key investors?
A.□ Advantage Capital Partners
B.□ Goldman Sachs
C.□ Others
1.A.2.C Who are your key investor(s)? // For response C to qn 1.A.2 this is a sub-question of type i/p text.
2. What is your annual revenue? // Parent question#2 which can also have sub-questions
A.○ $5-$10 million
B.○ $10-$15 million
C.○ $15+ million

Need help setting up a project using Struts

Hello,
I have been following tutorials on using struts and came to succeed in creating the first examples from the book I am mainly relying on. Although there is only one problem left which isn't addressed in the concerned book, which is the fact I have 3 jar files which remain locked when I try to undeploy the application. These files are commons-digester.jar, commons-validator.jar and struts.jar which are located in the WEB-INF/lib directory.
I have been testing a few things in order to find the problem and it would seem to be with the ActionServlet since removing it from the web.xml configuration file made it possible to undeploy successfully.
The application I am trying to do is a simple example based on the struts-blank.war file that comes with Struts 1.2.4 with a few modifications:
-changed the entry for message-resources in struts-config.xml for
<message-resources parameter="application" />
-Moved the application.properties file to the WEB-INF/Classes folder instead of having it in WEB-INF/Classes/Java/resources
Thanks in advance
