Query Builder in Web application

Hi, I want to develop a web application, which include query builder for database using Jdeveloper nad ADF. In this application must be page with this queries and execute them. The problem is that i have no idea how to realize it, Please help me
Manuals, links and other information would be good.

<puts flame shields on>
APEX has this out-of-the box, perhaps that would be a better tool for the job?

Problem with tutorial; "Build a Web Application with JDeveloper 11g Using "

I've got a rather new installation of Vista Business x64 on my developer rig, and last week I installed the new JDeveloper 11g version. The installation was all-inclusive, no customization on my end.
In addition I've got a test installation of an Oracle DB 11gR1 on an available server here.
To familiarize myself with the new JDeveloper I decided to spend some time with the JDeveloper 11g tutorials found here: http://www.oracle.com/technology/obe/obe11jdev/11/index.html.
I've started twice on the second tutorial, "Build a Web Application with JDeveloper 11g Using EJB, JPA, and JavaServer Faces", and find myself repeatedly stuck at step 19 in section "Creating the Data Model and Testing it".
It seems impossible to deploy the application to the default application server. The server starts fine on its own, I can access it via the admin console on port 7001 and it looks good. However, when I try to run the HRFacadeBean funny things are happening, symptomized by the following error messages seen in the IDE log-area:
The "Messages" pane displays:

I'm not that familiar with these things but it seems to me that there is an issue with port numbers here. The application seems to expect a app.server service at port 7101, but does'nt find one.
Any suggestions on how to fix this problem would be appreciated?

Jupp,
It fails in a similar way.
What I did was; create a simle 'Hello World' html file, saving it with the jsp extension. In Jdev11g i made a new application and an emtpy project, then loaded the jsp file and made it the default run-target. This compiles nicely.
When running the project it first attempts to start the WebLogicServer (WLS). After a few minutes it is started as seen in the "Running: DefaultServer" pane:

But, of course, the server is actually running as I can access it via its Admin Console.
So, I try to run the project again, and this time the following is shown in the "Messages" pane:

The "Running: DefaultServer" now comes up with:

[waiting for the server to complete its initialization...]
[Server Instance DefaultServer is shutting down. All applications currently running will be terminated and undeployed.]
Process exited.
The WLS is still running though as I can still access its adm console.
To me it seems that it is attempting to start a separate instance of the WLS for each run attempt, but then I could be wrong.....:(
Later I'll try to change the default WLS port from 7001 to 7101 as suggested in another port here.
I must admit that I'm a bit surprised that the JDev11g doesn't work fine at this very simple level when performing a default install.

Help Building Simple Web Application

So i've decided to build an online football pool application. I've decided its going to be built in java. I have spent some time going through java tutorials and learning what i can on my own.
I've decided to use Apache Tomcat 4.1 as my web server and jsp/servlet engine. I know i am going to also use SQL Server as my database (i was able to get my hands on a copy)
I want to separate my presentation logic from business logic. I plan on implementing my business logic using java beans that will reside in the web-inf/classes directory of my Tomcat directory.
1) Am I headed in the right direction?
2) Does anyone know of a good hands on book/web site that describes building a web application from the ground up using a similar architecture as described above. I have a lot to learn about java as well but prefer to learn it hands on.
I appreciate any and all feedback.

some interesting links...

Call BW query from a Web application

Hi,
I am trying to call a BW query from a Web application. Could you please let me know how to pass the parameters to the query.
Thanks,
Rekha

I don't know about db2 APIS, but you can use JDBC to connect to DB2 physical files/tables with the DB2 driver. You would need the jar file with the driver info though. I've done this with the webshpere appserver.
import com.ibm.db2.jdbc.app.DB2Driver;
Class.forName("com.ibm.db2.jdbc.app.DB2Driver");
connectionVar = DriverManager.getConnection("jdbc:db2://SERVERNAME/LIBRARY", "user", "passwd");
That's the basic info that will get you connected and then you can access any files or tables that are in that library with SQL. You would have to use the Java API though - statements, resulsets etc. Hope it helps.

SQL Azure: Query Analyzer VS Web Application - Calling Stored Prcocedure

I have a stored procedure in SQL Azure.
Calling this stored procedure normally would take 30 minutes.
I need to call this Stored procedure multiple times (18 times, with different input)
Scenario 1: When I call this asynchronously from the Web Application, all 18 calls run concurrently so the whole process take about 30 minutes.
Scenario 2: When I call this same stored procedure from Microsoft SQL Server Management Studio, (each process in a different TAB) they seem to be running very slowly, it has already taken more than 5 hours.
Is there a reason for this ?
Is there any difference in calling multiple stored procedures from different tabs ?
Is this process running Asynchronously ?
What is the best was to achieve scenario without going via the front end ?

Is there a reason for this ?
--When you are running the query, no matter application or SQL Server, please check sys.dm_exec_requests and check the session status in SQL Server and see if any difference.
Maybe it is caused by blocking when running in SSMS. We need to dig into it.
I am not sure how you call the procedure asynchronously in application, but if they are sent to SQL Server within different connections/sessions, then it should be the same as SSMS.
Is there any difference in calling multiple stored procedures from different tabs ?
--No.
Is this process running Asynchronously ?
--When you start the procedure in SSMS, it is a synchronize session.
However, the slowness should not be associated with the synchronization or not.
Per my understanding, for the asynchronously calling in application, it simply means that application goes to execution other code without for SQL Server.
This does not affect the real time cost in SQL Server.
What is the best was to achieve scenario without going via the front end ?
--We need to understand what cause the issue first. Normally they should be almost the same.
Right now the procedure caused 30 minutes to complete and it is really too long. I think you'd better make adjustment to the code or logic to tune the performance first.

Query Builder - Find WEBI reports that are using a table

I am trying to find list of WEBI reports using a specific table. This specific table is used in only 1 universe.
Though I could successfully find list of reports that use this universe, I am unable to find drill down further and find the subset of reports using this table/object.
SELECT si_name, SI_KIND, si_id, SI_PARENTID,SI_AUTHOR,SI_OWNER FROM CI_INFOOBJECTS, CI_APPOBJECTS
WHERE PARENTS("SI_NAME='WEBI-UNIVERSE'","SI_NAME ='MyUniverse'")
Is it possible to find the information I am looking for using query builder.
Also, for a given WEBI report I am trying to find the list of report names and the folder they reside in:
Select SI_NAME, SI_ID, SI_PATH, SI_KIND, SI_OWNER From CI_INFOOBJECTS, CI_APPOBJECTS WHERE
PARENTS("SI_NAME='Folder Hierarchy'",
"PARENTS('SI_NAME=''WEBI-UNIVERSE'' ', 'SI_NAME=''MyUniverse'' ')" )
The above query just gives me the folder names. I am looking to find the report names as well the the folder (and preferably the path) in a single query. Is that possible.

Sri,
With respect to your 1st requirement:
In BusinessObjects 6.5 it was possible. However, post BOXIR2 this information could not be retrieved from CMS via query builder. I agree with Jorge Sosua's comment above.
With respect to your 2nd requirement:
The field 'SI_PATH' will retrieve Filestore path(physical path). If you were referring logical path(Public folder path or psuedo-reference path) will you please refer my respone to Kelly Stone at BusinessObjects Query builder queries - Part II , If this may assist you.
Regards,
Sandeep

Query on WAD (Web Application Designer)

We have got request from the user on one WAD u2013 Web Application Designer Report for the extra functionality.
This WAD report contains 7 tabs, for each tab there is a separate query view has bee designed with default variable values.
While running the WAD report user will input values in the variable window for the variables (Eg: Fiscal Year, Org.Structureu2026etc), after executing the report, if the user switch to another tab in the same report, the variable values entered before execution of the report will not pass to the another tab by default because the query views have been designed in such a way that each query view will have its own default values.
Now the user is expecting the variable values entered for the first tab should be passed to other tabs as well, is it possible to pass values from one tab to another tab?
If its possible, could you guide us where (HTML code or web template parameters or any another things) exactly the required changes/modifications need to be made in WAD report?
Thanks in advance.

Query Builder in Oracle Application Express

I am unable to get columns to show after I submitt an object and click "columns" to add for a query. I also cannot get any query at all. Any help out there?
Feel free to direct me to correct forum if necessary.

Hi Latha,
I believe in APEX 4.0 you can do that.
For now you would need to write a query builder yourself... (it's just an APEX app)

Tipps for building a web application

I have an idea for a web application. It is fun do do it and if well done, it can earn much money.
There are two people now working on it, inlcuding me. I develop the concept, write the servlets. He is good at XHTML.
What other skills does a typical web application need?
I think we need someone with law skills. If the application comes out, it may not contain any legal weaknesses. Otherwise competitors could destroy us easily. We would have no money to defend ourselves until the application earns money.
Of course we would also need someone who is good at business laws. A company has to be founded and so on.
How many people does a medium complex web application need? And what skill sets? What are important things to consider?

I'd say you need someone with A LOT experience and A LOT of knowledge in existing technologies (if youre doing e 90s style e-hype startup). And have an idea noone had before, because there is A LOT of existing solutions to almost any problem sold A LOT of times from A LOT of huge companies with A LOT of money.
I dont want to destroy you motivation but i think its gotta be more than 2 Quereinsteiger to earn money with j2ee on web. If it was i'd be riding a ferrarie and not doing student assistance at university or coding web apps for t-systems.
Still.. DO IT! 'Cause its really fun to learn the stuff and j2ee is a really nice framework. But go into details of j2ee and dont start coding servlets like you would 'code' html.

Tutorial for Building Mobile Web Applications Using ADF/BC4J-problem

This is the tutorial for:
Develop a offline, Web-based Disconnected Mobile application
Trying to create an offline mobile application using jdeveloper & oracle lite. I want to be able to update the home database after using the application in a disconnected fashion. I do not have a web site, nor is that a feasible option.
Jdeveloper 10.1.3.4 which should be OK as it is higher than the release specified in the tutorial.
webtogo
oraclie lite 10
oracle 10.
I have tried to follow the tutorial completely and I can not get this to connect from webtogo. It runs fine in the jdeveloper usising the container. I created the war file, did the wtg packaging process, opened the mobile manager and published the application & granted access to user 'john'. The samples provided work fine. The new application appears on the webscreen after installing web 0c4j. When I click on it, the address toolbar shows:
http://localhost/webtogo/bc4jtutorial/faces/CustomerOrders.jsp
When it installed mobile client, it installed the CustomerOrders.jsp into:
E:\mobileclient\mobile_client_oc4j\j2ee\mobileclient\applications\mobileclient\bc4jtutorial
an example of the samples that work shows
http://localhost/webtogo/sample6/list
in the browser address line.
Which looks like it's really
E:\mobileclient\mobile_client_oc4j\j2ee\mobileclient\applications\mobileclient\samples\sample6
on the file system
Any one have any ideas? I'll take another solution if someone has found one. However, i am not a great java programmer so thought jdeveloper was great to create forms and access the database.

Tutorial: Build a Web Application (JSF) Using JPA

Hi,
I am trying the subject tutorial at
[http://www.oracle.com/technology/products/ias/toplink/jpa/tutorials/jsf-jpa-tutorial.html#CHDIIEHA]
and it seems I have to install OC4J and TopLink JPA.
I will appreciate if anyone explain me if it is necesary, and in case of it
witch is the reasson.
I have some configured enviroments to develop JEE 5. I am talking about Eclipse Galileo against JBoss
and NetBeans 6.7.1 aginst glassfish v2ur2
Thanking in advance,
Jose

You might want to ask your question in a JDeveloper/ADF forum. With JSF/JPA, the only reason for XE is to provide a JDBC Data Source, so this product is hardly used.
Once you move to JSF, you are switching to a 3-tier (or n-tier) software model, and the middle of the tiers is OC4J. So you need to get that. And TopLink provides the connection to the database.

Query Builder in 3.0 Can it be called and used as part of an application

The query builder component is nice from an end user perspective. Can it be called in version 3.0 as part of an application? i.e. the user gets the tables listed in the app and can create the sql query as done when building the app? If so, does anyone know why not? Seems like all you'd have to limit it to would be the all_tables view where owner = 'application owner'. Has anyone tried to call this module?
Bob

HI Bob,
No you cannot call the query builder from your application.
You have a couple options though, one is to give the user developer rights, and then they can access the query builder, or you can search the forum for QBE, and that will generate 3 pages of hits. There's a couple generic variations out there that may suffice.
Hope this helps,
Bill Ferguson

Activate the Query Builder 2.0 in the application

Hi all,
is it possible to activate the query builder inside the application?
With the custom theme.
The query builder should be accessible through a link...

This is not possible.
