Extjs-4.1 instllation in apex 4.1

Dear friends
i want to integrate extjs in apex.
I downloaded the extjs 4.1 gpl from its home website
i think i have embedded PL/SQL gateway to connect to the server.
so 1st i useed this command to set the port. by login as system user
SQL> exec dbms_xdb.setftpport('21');
PL/SQL procedure successfully completed.
SQL> alter system register;
System altered.
After this i connected to the the localhost server ie:127.0.0.1 by using filezilla
then i created a folder named /ix/ and transfered the extjs-4.1 folder to ix folder.After transfer complete i closed filezilla
and now i want to run extjs by using this link
http://hostname:port/ix/themes/ext-4.1/examples/index.html
But i am confused about the port.
Here my hostname is :127.0.0.1 and
what port number i use.if use port 21 the one i set it shows me error
please login as username and pass
then which port to use
my apex is installed in port 8080
The steps i told are present in this book: Oracle Application Express 4.0 with Ext JS
but it is not working or i did some mistakes
So please can anyone tell me how to do it because i am trying for several time and facing the same error.
Please hepl me

Extjs installation in apex 4.1.1

Dear Friends
Can anybody tell me what version of extjs is to install in apex 4.1 and
also how to install in apex 4.1 step by step.

Start from here
The installation process remains the same. Only ApexListener is not mentioned as it did not exist then, but it is roughly the same as OHS.
You may install the latest version available for download.

Oracle apex and extjs grid table

hi
im new to extjs and i was wondering if someone can help me with this;
i want to create a report in oracle apex and put the output in extjs grid table
for example i want to view the output of select * from all_objects in grid table
thnx in advance

Okay
To get you started...
Create a new report template with named rows.
In row 1 template put this
["#1#","#2#","#3#","#4#","#5#","#6#","#7#","#8#"]Assuming you have 8 rows say... and make it conditional based on a PL/SQL Expression like this
#ROWNUM# = 1Then row 2 template like this
,["#1#","#2#","#3#","#4#","#5#","#6#","#7#","#8#"]Conditional on
#ROWNUM# > 1Then in before row put this
<script type="text/javascript">
Ext.onReady(function(){
var munkyData = [And after rows something like this (based on the emp table)
var store = new Ext.data.SimpleStore({
      fields: [
               {name: 'empno', mapping: '0'},
               {name: 'ename', mapping: '1'},
               {name: 'job', mapping: '2'},
               {name: 'mgr', mapping: '3'},
               {name: 'hiredate', mapping: '4'},
               {name: 'sal', mapping: '5'},
               {name: 'comm', mapping: '6'},
               {name: 'deptno', mapping: '7'}
store.loadData(munkyData);
var grid = new Ext.grid.GridPanel({
       store: store,
       columns: [
                 {id:'empno',header: "Employee",sortable:true, width:100,dataIndex:'empno'},
                 {header: "Name", sortable:true,width:75, dataIndex:'ename'},
                 {header: "Job", sortable:true, dataIndex:'job'},
                 {header: "Manager", sortable:true,width:75, dataIndex:'mgr'},
                 {header: "Hire Date", sortable:true,dataIndex:'hiredate'},
                 {header: "Salary", sortable:true,width:50,dataIndex:'sal'},
                 {header: "Commission", sortable:true,dataIndex:'comm'},
                 {header: "Department", dataIndex:'deptno'}
       stripeRows: true,
       width:700,
       autoHeight:true,
       title:'Array Grid',
       renderTo: 'munkyDiv'
</script>Then create a region to hold it with a source of
<div id="munkyDiv>
</div>
{code}
This is pretty basic but it should get you going...
Cheers

Extjs framework in apex 4.0

Does apex 4.0 uses extjs framework internally?
thanks
Seetharaman

APEX 4 uses JQuery libraries internally, although you have to manually reference the non core JQuery UI components such a tabs, accordion etc...
I implemented ExtJS on APEX 3.2 after reading Mark's blogs on the subject, I've also read Mark's book which is excellent for ExtJS APEX integration.
Other could good sources of ExtJS APEX integration info are blogs by Tobias Arnhold, E-DBA, Matt Nolan, Anja Hildebrandt amongst others.
Things to watch out for:
The size of the full ExtJS libraries CSS combined with the default APEX JS and CSS files and any of your own application scripts etc... can add up to a couple of MB so users on slower connections can suffer page load issues so make sure that you use minified versions where possible and ensure you have good caching and compression implemented.
Also recommend using PPR technics, ext popup windows etc... to avoid full page refreshes where possible.

ExtJS Grid and Apex

I have been experimenting quite a bit with ExtJS and unfortunately hit a roadblock and thought of getting help from this forum. I followed the directions given in this post Re: oracle apex and extjs grid table and was able to make it work. However the Grid is displaying outside the region where it has been defined as if it is independently rendering in its region of choice.
I could post the screen shot and don't know how to work around the restriction of this message board, not allowing any attachments.
Any help is greatly appreciated.
Environment info: Apex 4.0
Local host,
ExtJS: 4.0.2
Thanks
Raja

The book was written to use Ext JS 3.x, the latest production version at the time.
Some of the examples will work, some will require rework. Sencha have published a migration guide, including a <b>compatibility layer</b> that bootstraps existing Ext JS 3 code to run under Ext JS 4.
The book promotes the idea of not updating your application templates, instead having a template application which allows you to test your components before publishing a new version of the theme to the business application.
If you are just starting out, you could drop in the books theme as version 1 using Ext JS 3.x, get your team working on the application immediately, and have a dedicated resource working on theme version 2 using Ext JS 4.x.

Mark

Apex listener images deployement

Hi
I installed the APEX listener recently. I have a question. Can I deploy the images in a different way other than jar them and then deploy to WLS. I have a lot of custom images/javascripts reside under the /i/ virtual path (e.g. /i/extjs). The images and javascripts change frequently. I guess that every time this happens I have to create a new i.war and redeploy which is not so convenient. Is there any other way to do that (e.g. copy them directly to a directory as I was doing with OHS/modplsql)
Thanx
George

Hi George,
you could do this by locating the directory where the WLS has unpacked the deployment to. But the more I think about this, the more I think you shouldn't do that, because staging etc. makes this very complex again.
Instead of deploying the images as war file, you could add a virutal directory mapping, which is far easier.
It should be possible to do that in the weblogic.xml of the apex.war (unpack the war, edit the file, repack the war, similar to what you'll do if you edit the web.xml, e.g. to change to config.dir parameter). See the [url http://download.oracle.com/docs/cd/E13222_01/wls/docs81/webapp/weblogic_xml.html#1039396]corresponding part of the WLS documentation for details on that parmaeter. The result could be a weblogic.xml as follows
<weblogic-web-app xmlns="http://www.bea.com/ns/weblogic/weblogic-web-app">
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
<virtual-directory-mapping>
<local-path>/opt/oracle/apex/images</local-path>
<url-pattern>/i/*</url-pattern>
</virtual-directory-mapping>
</weblogic-web-app>if your images are stored in */opt/oracle/apex/images* .
Not that this can cause node specific dependencies if you have a clustered WLS, and that you'll have to undeploy the i-application before you can redeploy the apex.war.

Using Clobs As An XML Datagrid Source (extjs)

I'm still playing around with the extjs library and have decided to try an xml-grid next.
I know I can call an application process for a URL so I was thinking I'd probably use that to get the resulting XML.
I also know I can create an application process easily enough using dbms_xmlgen.getxml to get the document.
The problem is, I'm not really sure how to get from here to there. :)
From what I understand, the application process doesn't return a value.
Do I need to create a directory and have the application process fire not from the grid, but from within the page and then use UTL_FILE write to that directory? I was hoping to just be able to write something that would return the data as some kind of object that then I could reference from within the javascript directly without having to create files every time someone clicks on my page.
Or maybe my approach is way off base. :)
Thanks,
Chad

Hello,
Use an Application OnDemand Process.
I have an example here of pulling xml (for an SVG image) but the concept is the same.

Hi All,
there is some thing wrong in documentation of Apex 4.0.1
when i read to configure Embadded Pl/SQL gateway i followed everything from documentation and after instllation it is mentioned how to login to Apex as follwoing.
http://hostname:port/pls/apex/apex_admin
in following statment which i copied from documentation does not describe anything for "PLS". which is making confussion to me that there is something i missed during installation.
3.4.12.1 Creating a Workspace Manually
To create an Oracle Application Express workspace manually:
1.Log in to Oracle Application Express Administration Services. Oracle Application Express Administration Services is a separate application for managing an entire Oracle Application Express instance. You log in using the ADMIN account and password created or reset during the installation process.
a.In a Web browser, navigate to the Oracle Application Express Administration Services application.
Because your setup uses the embedded PL/SQL gateway, go to:
http://hostname:port/pls/apex/apex_admin
Where:
hostname is the name of the system where Oracle XML DB HTTP server is installed.
port is the port number assigned to Oracle XML DB HTTP server. In a default installation, this number is 8080.
apex is the database access descriptor (DAD) defined in the configuration file.
where as for installation chossing HTTP server it states to login by following
3.3.12.3 Logging in to Your Workspace
Once you create a workspace, you must log in to it using your login credentials (that is, the workspace name, user name, and password).
See Also:
See "Creating Workspaces" and "Managing Workspace Requests" in Oracle Application Express Administration Guide
To log in to your workspace:
1.In a Web browser, navigate to the Oracle Application Express Login page.
Because your setup uses the Oracle Application Express Listener, go to:
http://hostname:port/apex
Where:
◦hostname is the name of the system where Oracle XML DB HTTP server is installed.
◦port is the port number assigned to Oracle HTTP Server. In a default installation, for Oracle WebLogic Server this number is 7001, in OC4J this number is 8888, in Oracle Glassfish Server this number is 8080. These defaults are correct at the time this document was written. Please review the related Web server documentation for the latest default port if necessary.
◦apex is the mount point defined in the Web Server configuration file.

b The nicest APEX app / feature /b

Hello,
At ODTUG I'm doing the APEX vs ADF Shoot-out, together with Lucas Jellema.
The last presentation Lucas and I did last year in the Netherlands. We decided to change some things in the presentation. One of them is to include "the nicest app or features in both environments".
So, I thought to ask the community what they think I should show.
Currently the list I thought to chose of:
* Out of the box in APEX: from raw Data to Application and Interactive Reports
* "Web 2.0" extensions in APEX: for ex. ExtJS and Dhtmlx
* Integration with Webservices, Fusion and SOA
* Extending E-business suite with APEX
(although I don't have the Oracle Applications Suite running on my laptop, so it will be hard to show)
* Integration with SQL Developer
I've about 15 mins to show the coolest, nicest features or application around, build in APEX. So it's not necessary to show things in dept or explain how to do them.
What features do YOU think make APEX incredible? Feel free to send me some screenshots or even nicer real demo sites or an application export I can show.
I know a lot of the applications we build are "internal" only, but if you could make a subset of it to just show the cool feature, that's already fine. If you just want to share what you think would be cool to show, just add a comment ... there might be a chance I already did some testing with it.

Let's show the ADF guys something ;-)

Dimitri

Hi Peter,
I have a very nice anecdote about 1. APEX for Dummies!
In DG Tournament there was a problem, people couldn't login... but I didn't have an internet connection at that time and as people had to bet on the games it had to be fixed asap.
So I called my brother (as he was one of the only persons I could reach) and asked him to follow my instructions. In 5 minutes it was fixed! He's a teacher in sports, so NOT technical at all. He could do everything with his browser, no need to redeploy or have tools on his pc. I should blog about it, but then I'm not sure if the ADF guys read it, they will shoot at that ;-)
I don't want to stress 1 too much, as APEX is/was seen like that before and the marketing is also done like that by certain people, but as you also say in 2. APEX is very powerful. I see it as a fit for a lot of people; from business people who have not many technical skills to the guru developers.
Regards,
Dimitri

ExtjS Panels - Does not appear.

Hi All,
I have apex 3.2 with extjs 2.2 working correctly. All my panels logo, menu and work areas appear. We have upgraded to Apex Application Express 4.1.0.00.32 and now the application just hangs. I was receiving errors in firebug but after moving the #HEAD# tag to after all the javascript inclusions all errors have been resolved but now the app just hangs. I have a report region which displays incorrectly but none of the extjs panels display.
See related previous thread to resove #HEAD# issue -- apex.jQuery is not a function
Any help and pointers, notes to previous posts welcome.

Apex LE/D 4088 Assistance

I saw that there was a group of users who had the Apex 40" LE 4088 television on an earlier post and wanted to follow up with those users as this information doesn't seem to exist anywhere else and customer service with Apex is non-existent.
Does anyone know, or have available to measure, the size and type of screw used to secure the podium to the flatscreen panel? This is not to say the stem, but rather the foot for table-top usage. I apologize if this is off-topic, but I am trying to track this information down and having difficulty.
To make matters worse, I can't just try a bunch of screws or take measurements as my partner has the unit and is two states away and I would like to be able to just order the screws for her online and have them shipped directly to her so this isn't just one more thing for her to deal with on top of moving and starting a new job.
If someone could help out, it would be huge.

Hi,
Do you load extra JavaScript libraries (e.g. extjs) in page template header?
Try move #HEAD# substitution string before any extra library, in page template header.

From Apex 4.0 release note
http://docs.oracle.com/cd/E17556_01/doc/relnotes.40/e15512/toc.htm#BABBGDJD
>
*3.8 Including Different JavaScript Libraries*
Oracle Application Express release 4.0 includes the jQuery JavaScript library (Version 1.4.2) and jQuery UI JavaScript library (Version 1.8). If you wish to include a different version of either of these libraries, or any other JavaScript library using $ as a global namespace, then you need to include them after the #HEAD# placeholder in the Definition > Header section of your application's page templates. This ensures that your versions of the libraries are available.
Note that prior to Oracle Application Express release 4.0, you could include the jQuery libraries before the #HEAD# placeholder. Includnig jQuery libraries. With the inclusion of jQuery libraries that approach is no longer supported.

Extjs grid with pagination

hi,
i just start learning how to integrate extjs with oracle apex.
i manage to create a normal extjs grid but got problem when trying to create
a grid with pagination.
lets say ihave 100 rows of data, and i want to show only 10 rows of data per page, so how should i do that?
i know i need to send a request to so that i will get data 1-10 for the first page, and then when i click next,
i will get data 11-20 and so on.
but i dont know how to make it happen. i cannot find any example on the net.
how to know what is the current data set, (is it 1-10 or 11-20) , so that i can pass the correct values for start, to the application
process?
hope someone here can help me.
thanks,
-aku

Hi Aku
As far as I recall, alot of this came from Mark Lancaster so I would advise googling for his blog and having a look there - it may well make a lot more sense than this does.
I normally build my ExtJS script up at page loaed time using a package and print it out using htp.prn. So for the pagination, I would print out something like this...
    htp.p('<script>var u = (window.location.href.indexOf("?") > 0) ? window.location.href.substring(0,window.location.href.indexOf("?")) : window.location.href;
           var baseURL = u.substring(0,u.lastIndexOf("/"));
           var gridURL = baseURL + ''/wwv_flow.show?p_flow_id='' + Ext.getDom(''pFlowId'').value + ''&p_flow_step_id=0&p_instance='' + '||
          'Ext.getDom(''pInstance'').value + ''&p_request=APPLICATION_PROCESS%3DejPaginate'';</script>');And then my store would be defined as something like this...
myStore = new Ext.data.Store({
              storeId: 'myStore',
              proxy: new Ext.data.ScriptTagProxy({
              url: gridURL,
              nocache: false,
              callbackParam: 'p_widget_num_return'
              baseParams: {'x01':'&APP_ID.', 'x02':'&APP_PAGE_ID.', 'x03':'xyz'}, //the xyz would be your region
                                                                                   //ID passed into the procedure I gave you in my previous post
              remoteSort: true,
              paramNames: {
              start: 'x04', // The parameter name which specifies the start row
              limit: 'x05', // The parameter name which specifies number of rows to return
              sort: 'x06', // The parameter name which specifies the column to sort on
              dir: 'x07'    // The parameter name which specifies the sort direction
              reader: myReader
              });And my application process (ejPaginate in the above example) would look something like this...
BEGIN
htp.p(wwv_flow.g_widget_num_return||'(');
get_grid_json(p_app_id => wwv_flow.g_x01,
                    p_app_page_id => wwv_flow.g_x02,
                    p_region_id => TO_NUMBER(wwv_flow.g_x03),
                    p_start => NVL(wwv_flow.g_x04,0),
                    p_limit => NVL(wwv_flow.g_x05,10),
                    p_sort => wwv_flow.g_x06,
                    p_dir => wwv_flow.g_x07);
htp.p(')');
END;Hope this helps you along.
Cheers

Extjs grid or jquery jqGrid

Hi,
Has anyone successfully integrate Oracle Apex with extjs grid or jquery jqGrid? How can I call an onDemand process to return XML or JSON data and use that for those grids?
Thanks.
Andy

Hi Andy
It's easy enough to integrate the extJS grid, you just need to break the problem down into a series of small steps.
To tackle the problem, I'd do the following steps.
1. Copy a extJS grid example, with the grid data embedded in the page.
2. Once step 1 works, move the grid data into a PL/SQL package, and call this via a application process.
3. Once step 2 works, work out how to create the grid data dynamically in your PL/SQL package. Make sure you consider escaping your data if returning JSON.
4. You get the idea...
It's just a case of chipping away at the problem, and learning as you go.
I don't have a grid on my [demo site|http://apex.oracle.com/pls/otn/f?p=200801:1:], but the examples should help with creating an application process, and you can see the JSON data being returned in Firebug.
In case your wondering why I don't have an extJS grid...
If I built a one off solution my users would immediately demand that functionality everywhere, and I'd have to do a whole lot of work to build a complete generic solution.
It's much easier to use the Apex interactive reports for read-only, and AJAX enabled updatable reports with a bit of CSS to get a good looking solution.
