Jdev 11 Question

Hi Sir/Madam,
Since,I have develop master-details forms by Oracle Forms and have import & export excel function. Pls advise Jdev 11 can do it or not ?
My meaning of Master-Details forms is no need seperate page to insert details records. if yes, where have tutorial or sample application.

UIX related JDev question.

Hello,
I am currently using the printable facet in some of my applications.
I was wondering if their was way to create a facet that would ressemble the printable facet, but with all the chrome and some functionnalities.
Basically I would like to create the default facet except with all form values in read only mode. Would this be possible?

what method are you trying to call?
I don't see a
setAttribute(..) method on ApplicationModule.
Can't your create page get the "code" paramter directly from
the url using:
${param.create}
?

Ide.user.dir in Jdeveloper 12c

Hi Gurus,
I am just installing Jdeveloper 12c 64 bit for windows. There is another Jdeveloper 10.1.3.3.0 already in placed which i want to keep for EBS R12 OAF extendsion development.
Jdeveloper 10.1.3.3.0 was installed in D:\JDEV\1213\jdevhome\jdev and environment variable JDEV_USER_HOME is set to D:\JDEV\1213\jdevhome\jdev
Jdeveloper 12c was installed in D:\oracle\Middleware\Oracle_Home\jdeveloper
I created new environment variable JDEV_USER_DIR and set it to D:\JDEV_121200_win64\jdevhome\jdev, but notice some different behavior for ide.user.dir entry after Jdeveloper launched.
Scenario 1: Launch Jdeveloper 12c with command : jdev.exe -J-Dide.user.dir=D:\JDEV_121200_win64\jdevhome\jdev
                   In Help->About->Properties, value of :
                   ide.user.dir = D:\JDEV_121200_win64\jdevhome\jdev
                   ide.pref.dir = D:\JDEV_121200_win64\jdevhome\jdev
                   Systemxxx folder created in D:\JDEV_121200_win64\jdevhome\jdev\system12.1.2.0.40.66.68
Scenario 2: Add ide.user.dir entry = D:\JDEV_121200_win64\jdevhome\jdev in jdev.boot
                   Launch Jdeveloper 12c
                   In Help->About->Properties, value of :
                   ide.user.dir = D:JDEV_121200_win64jdevhomejdev
                   ide.pref.dir = D:JDEV_121200_win64jdevhomejdev
                   JDEV_121200_win64jdevhomejdev folder created in D:\oracle\Middleware\Oracle_Home\jdeveloper\jdev\bin
Question : Why ide.user.dir and ide.pref.dir entry are not created with "\" ? Why JDEV_121200_win64jdevhomejdev folder is created whereby i wanted to be in
                  D:\JDEV_121200_win64\jdevhome\jdev?
Scenario 3: Launch Jdeveloper 10.1.3.3.0
                   In Help->About->Properties, value of :
                   ide.user.dir = D:JDEV_121200_win64\jdevhome\jdev
Question: How to keep the ide.user.dir for this version remain to point to D:\JDEV\1213\jdevbin instead of D:JDEV_121200_win64\jdevhome\jdev?
                 Is there any impact when i leave it to point to D:JDEV_121200_win64\jdevhome\jdev?
Regards,
Fendy

I change ide.user.dir in both files and it works.

Re-intializing a .JSPX pagedef variable iterator value?

I am using ExecuteWithParams operation to create an ADF parameter (search) form on a .jspx page. By default, the attributes reference a variable iterator which are stored in the request scope (see excerpt from developer's guide below). I can save the inputvalue from the parameter form to a processScope variable by using a setActionListener that is fired when the user presses the commandButton. However, how can I re-intialize the inuptvalue on the search form (using the value saved to the processScope variable) when the .jspx page is re-loaded?
-------------- code snippets --------------------------------------
// search.jspx page - inputvalue on search form
<af:inputText value="#{bindings.keywords.inputValue}"
label="#{bindings.keywords.label}">
<af:validator binding="#{bindings.keywords.validator}"/>
</af:inputText>
// search.jspx page - setActionListener to save inputValue to processScope
af:commandButton actionListener="#{bindings.FindMethod.execute}"
text="Search">
<af:setActionListener from="#{bindings.keywords.inputValue}"
to="#{processScope.keywords}"/>
</af:commandButton>
// searchPageDef.xml - variable iterator used to store variables for ADF parameter form
<executables>...........
<variableIterator id="variables">
<variable Type="java.lang.String" Name="FindMethod_keywords"
IsQueriable="false"/>
</variableIterator>
<bindings>......
<methodAction id="FindMethod" MethodName="FindMethod
RequiresUpdateModel="true" Action="999"
DataControl="SearchServiceDataControl"
InstanceName="SearchServiceDataControl.dataProvider">
<NamedData NDName="keywords" NDType="java.lang.String"
NDValue="${bindings.FindMethod_keywords}"/>
</methodAction>
<attributeValues id="keywords" IterBinding="variables">
<AttrNames>
<Item Value="FindMethod_keywords"/>
</AttrNames>
</attributeValues>
-------------excerpt for developer's guide ------------------------------------------------------
Because you dropped the ExecuteWithParams operation, the attributes reference a
variable iterator that accesses the variables instead of a collections iterator. This is
because the operation (unlike the returned collection) does not need to access an
instance of an object; therefore, there is nothing to hold the values entered on the page.
Variables act as these data holders.
JDeveloper creates a variable for each named bind variable. The variables are declared
as children to the variable iterator, and are local, meaning they live only during a
single request, and while they are carried across subsequent post-backs to the same
form, they would be forgotten (and re-initialized) when a user navigates to some other
page.

Receive an answer to a difficult JDev question = Excellent.
Get working example code to solve your problem = Priceless.
Thanks for the reply, er, I mean code sample! This does the trick and was what I was looking for.
However, it does seem to have a side effect that has created another issue that I posted in a separate thread:
af:inputText value fields refreshed when a backing bean is used for value?

Custom Login Module from OAS 10.1.3.1

This may be more of a JDEV question as it has less to do with configuration...
Will a custom login module written for OAS 10.1.3.1 work in Web Logic? Or will I have to scrap my current custom login module?

MODERATOR: Can this be moved to the JDeveloper Forum please?

Apache Commons Net deployment fails to resolve, JDev classpath question

I wrote a wrapper to apache's most recent version of commons-net package (version 1.4.1) to allow me to execute FTP services from an Oracle 9i2 database. After adding the common-net .jar file to the JDev libraries, and including this library in my project, I debugged the code in Jdeveloper, then deployed to the Oracle 9i2 server. However, many classes of the of the common-net (and my code) failed to resolve in the database.
After downloading open source product DependencyFinder, and running against the Commons-net .jar file, I found that some packages were dependent on the Apache ORO regexp package. The ORO package, as far as I can tell, is not in any classpath that my JDev project uses. There is listed in the JDev libraries, a library called Apache Regexp, but I did not include that in the project, either.
After I downloaded the ORO package from Apache, added it to JDev's libraries, included it in my project, and added the ORO library to the list of classes to deploy (using the loadjava deployment profile), deployment to Oracle 9i2 of the my classes, the commons-net classes, and the ORO classes properly resolved.
My question is: Why did my application work under JDeveloper? How and where did it find the ORO classes?
The version of Java under which JDeveloper is running, and the version being used as the compiler for this project, is a new installation of JDK1.4.2_10.

Since the commons net 1.4.1 is compatible with jdk 1.3.1, I should only need to use loadjava on the .jar file. In fact, that works, given that there is no failure on load due to incompatible .jar or .class files structure.
But, I've just solved this part of the problem. The commons net 1.4.1 is dependent on, but does not include the Apache ORO library. Once the ORO library was deployed to Oracle 9i2, all common net 1.4.1 classes were resolved.
The "problem" is with JDeveloper. Without including the ORO library in the JDeveloper application, or in the classpath, it worked under JDeveloper -- the more surprising since I had never downloaded the ORO library from Apache. Only after downloading ORO, explicitly defining ORO to JDeveloper, and including ORO as a library in my JDeveloper project, did the deployment of the application to Oracle 9i2 succeed (though the application always executed successfully under JDeveloper).

JDev 11g: Task Flows,Rich Client- some questions to the Oracle team

Hello,
We're currently involved (early stages) in a large project with a Jan-Mar 2008 pilot delivery timeframe - one heavily including end-user customizable workflow elements, to which the aforementioned JDev/ADF 11 features would be a great fit.
Our plans so far were to go ADF with BC and include Shale or Spring WebFlow plus custom development to provide for the very same things that the feature-complete Task Flows will offer.
Questions:
1. Delivery timeframe - any unofficial pointers on the schedule for the next JDev/ADF releases?
2. Platform compatibility - Will the framework (ADF) run on J2EE 1.3 (OAS 10.1.2.x) or does it require 1.4+?
3. Design-time-at-runtime for Task Flows - Do we have it in the released bits? (Couldn't find it). Any pointers on how is it supposed to operate?
4. Am I right to think that what we're seeing with Task Flows is (among other things) a piece of the replacement functionality for the decommissioned Oracle Workflow subsystem (which bit us, by the way, as it was part of our original architecture).
5. Will Rich Client support older platforms than the currently supported IE7 and Firefox 2?
Thanks for any and all pointers,
Thanassis Stathopoulos
Athens, Greece

Thanks Shay,
http://www.oracle.com/technology/products/jdev/collateral/papers/11/newfeatures/index.html
Regarding my question 3 "Design time at runtime" - quoting from "JDeveloper 11g new features" at the above URL, under "ADF Task Flow". The third entry from the paragraph's end reads:
'Support for customization of task flows at runtime using "design time at runtime"'.
I was wondering what this is exactly - web-deployable editor to edit the flow definition after deployment?
Re your point 4, product replacement - with the feature set described in the paragraph above, Task Flows is much more than a Web UI controller. With "save for later", transactions, flow abstraction/nesting, BPEL outcalls, conditional logic, method calls etc etc it probably covers 50% of a typical workflow package and 75% of an embeddable workflow library (audit trail/timeouts/persistence nonwithstanding). This made me wonder whether it is part of a bigger, yet-to-be-announced OAS feature. Especially if one also considers the "design-time-at-runtime" sentence listed above.
Now, definition-wise, I guess it' s whether this feature set is considered half-full or half-empty :-)
Thanks again,
Thanassis

Question (JDev-Extension): Retreive class name with package info

To JDev Development team:
I'm developing an JDev 10.1.3 EA1 Addin. I have access to an oracle.ide.model.Node (the currently selected java code file from the Application Navigator / System Navigator).
Is there a way (inside the Extension API to convert this node to String representation of a qualified java class pointer (package.classname)? Or do I have to use extensive String manipulation on the filename with path?
Example:
If the file in the tree is:
casthouse
+ panel
    + casting
      + CastingPanel.java
    I want to translate this to casthouse.panel.casting.CastingPanel without having to use the Node objects URL.getFile() and manipulate the String object retreived from this, by removing path down to top-level package name and replacing all '/' with '.'.
I'm sure your API has functions to do this. Either in the JoT packages or in the navigator itself... I've looked, but I cannot find any answers to this in the Extension API javadoc. (ref. post no.4 in Question: Adding extension preferences panels as subnodes in the tree

Øystein Amundsen

If you have the Project in which the Node resides, then you can use Jot to get the information that you are looking for. If you don't already have it, you can probably get the project from the Context of the View.
For example;
Project prj = ... // Maybe use Context.getProject() to get this value.
Node node = ...
JavaManager jMgr = JavaManager.getJavaManager(prj);
SourceFile srcFile = jMgr.getSourceFile(node.getURL());
SourceClass srcClass = srcFile.getSourcePrimaryClass();
String clsName = srcClass.getQualifiedName();

JDev 10.1.3 Tool Question: Why ist there no /faces in URL when running JSF

Hallo,
I am developing an application with JDev 10.1.3, ADF Faces, Tiles.
Everything works fine, except the JDev support when trying to start a "tile" that does not contain a f:view tag. The url that is given to the browser by JDev does in this cases not contain the "/faces" part.
When entering the correct URL in the browser it works perfect.
Question: How does JDev identify then to add the "/faces" part in the URL and when not?
E.g. then a pure .jsp is "run" in JDev the URL that is given to the browser is without "/faces" - what is correct in that case. How does JDev know when pressing "run" that it is a pure .jsp or a "jsf .jsp"?
Thx Willi

good luck gettting a good answer to this! We're having the same sort of problem, when we deploy the application on the server we lose the /faces unless we manually put it in. On top of that we get a 'Faces_Servlet' loading in our servlet list instead of the needed 'Faces Servlet' loading(it sits unloaded the whole time). This may be also part of your problem, you may want to look into it. I'm currently working with oracle to try to solve this.
good luck!

Some question about Jdev's CVS Tools.

Hi,everyone
who can help me?
the question is:
When I create a new CVS connection and connect CVS server.If the CVS repository path include a Chinese world or letter ,the word would be replaced by "??".(I set the CVS Encoding to GBK)
How to let JDEV's CVS tools Support Chinese?
thanks.
by Alden Hoo

1. Correct Sun's tool sticks a lot of CSS things in there to get you this thing though.
2. Which shortcuts are you looking for? You can define all the shortcuts you need under the tools->preferences->accelerators menu option.
3. Backing bean can be automatically generated for you by JDeveloper - or you can add them to the jsf-config.xml file. I'm not sure what you are asking here.
4. At the bottom of your page you have three tabs - click the one called source to switch to the code view. (you can also right click the tab and choose split window).
If you are just starting with JSF and JDeveloper you might want to follow one of our tutorials to get you started:

Why not all jars picked up by ojdeloy and how to generate build.xml from command line and not JDEV GUI - quick question

Hi All
We have 11.1.1.7 ojdeploy to compile our app.
We notice in the log that not all jars are used in classpath arguments when we explicitly set them up for compilation.

1- Is it because it depends on how jpr or jws are configured ?
2- How can we automatically generate a build file of the application from command-line (as opposed to using Jdev IDE to click to generate a build.xml) ?

The first warning is happening because you're stating drivers for input devices without need. You haven't disabled hotplug so evdev gets used instead of kbd. This is normal, and you should change the driver line from kbd to evdev so that whatever options (if any) you've specified for the keyboard get parsed.
The second warning is about you not installing acpid.
The third I have no idea about, but look at the synaptics wiki. None of the (WW) are related to your video card.
And every card that has 2 or more output ports show up as "two cards". You also don't need to specify the pci port in xorg.conf. edit: this is the general case with laptops, might be different for desktops.
When I do lspci -v I get:

And it doesn't matter if it errs in trying to sli up with it self. That's just not a possibility.

Database Link Question in JDev.

Dear all,
How can I get/read data from Oracle 9i database in Jdev 10.1.3 (Oracle 10g database). I've created the database link.
Thanks for advance.

It depends on what you want to do. What is your use case?
If you want to query the database you can open the connection and browse the database objects and table content. You can also choose to start a sql*plus session and write what ever sql and pl/sql you need against the database.
If you are writing a Java application you must configure a JDBC connection and write classes to encapsulate your queries. Please, see the JDBC section on OTN. It has lots of usefull examples on this huge topic.

JDev 11g ADF Tree question on programmatically expand and select node

I have two questions:
1. I'm trying to automatically expand the first level tree nodes upon display of the tree. I tried to initialize a RowKeySetImpl object, and added ArrayList of first level nodes, and used setDisclosedRowKeys method. The tree nodes are not rendered properly. If I take the following code out, then the tree content is rendered properly. Here is my code. I have three nodes that I want to expand.
ArrayList node1 = new ArrayList();
node1.add(new Integer(0));
ArrayList node2 = new ArrayList();
node2.add(new Integer(1));
ArrayList node3 = new ArrayList();
node3.add(new Integer(2));
RowKeySetImpl expand = new RowKeySetImpl();
expand.add(node1);
expand.add(node2);
expand.add(node3);
this.mainTree.setDisclosedRowKeys(expand);
2. I have a Panel Splitter, on the first facet, it contains a tree, on the second facet it will be either 'task list', or 'edit task'. When user selects a task in the 'task list', I would like to display 'edit task', while highlight the selected 'task' node on the tree.
In respond to the ActionListener of the command link (each command link corresponds to task):
1. How do I determine the properly node in the tree?
2. I constructed a RowKeySetImpl object and called setSelectedRowKeys. But I get messagebox saying "To display the webpage again, Internet Explorer needs to resend the information you've previously submitted." If I clicked Retry button, the message box just gets displayed again. If I cancel, the node I hardcoded does get selected properly.
Please help me!
Thanks,

I believe this has already been fixed in our main code branch. I will enter a boxer bug and make sure that the fix gets backported to boxer so that it is available in the next boxer patch. If I remember correctly, the issue had to do with trees with a large display area (with default fetchSize of 25). The issue is that the tree has to make multiple round trips to the server in order fill the visible area (view port) on the page.
Do either of the following workarounds work:
1) Set a fetchSize attribute on the af:tree tag larger than 25 (<af:tree fetchSize="75">). You may want to increase the rangeSize in your pageDef file as well so that the model rangeSize matches the view fetchSize.
2) Shrink the size of the tree on the page so that it does not have to make multiple round trips to the server to fill it's view port.

Jdev. Report question

Dear all,
I am using Jdev. 10.1.3, ADF BC. Is it possible to run the Reports 6i in Jdev.? Or, need Reports 9i or higher? If so, how can I run it in Jdev.?
On the other hand, I prepared the XSQL and XSL (use FOP) in order to create report. I can run the XSQL by right click the mouse and choose "Run". But, how can I run it by clicking a button in the JSF form?
Actually, I am afraid XSQL + XSL is not flexible as Oracle report when creating some complex reports...
Thanks for any suggestion!!!
Regards.

Thanks Navneet!
Can you pl explain what exactly are you trying to accomplish?All of our existing applications were developed by Forms 6i and Reports 6i. Now, we used JDev. to develop the new project (Jdev is new for us). And we need create some reports, for example, summary report for each type of goods sales by / per month; receipts for goods, etc. (Our purpose)
I tried to use FOP (XSQL + XSL are created) to create some simple query and generated the PDF. But I concerned about how to create some complex reports? So, I think maybe we need to use Oracle Report. And I don't know the existing Reorts 6i support Jdev. or not. (Thanks that you are already explained this point to me.)
Moreover, how to implement the Oracle reports with Jdev.
Regards.
PS:
how can I run it by clicking a button in the JSF form?
For better response, this Q should be posted in JDev forums.
yes.

Jdev 11g: question about dvt:shapeAttributes and property "alt"

Hi,
Jdev 11.1.1.0.2
I use dvt:shapeAttributes> within a declarative component.
This code works fine:
          <dvt:shapeAttributesSet>
            <dvt:shapeAttributes component="GAUGE_INDICATOR"
                                 alt="Your Tooltiptext"/>
          </dvt:shapeAttributesSet>The tooltip text should come from an attribute (parameter) of the declarative component
          <dvt:shapeAttributesSet>
            <dvt:shapeAttributes component="GAUGE_INDICATOR"
                                 alt="#{attrs.tooltipLed1}"/>
          </dvt:shapeAttributesSet>But this gives an runtime error:

     at weblogic.work.ExecuteThread.run(ExecuteThread.java:173)From the documentation I can see the property "tag" takes an reference to backing bean.
http://www.oracle.com/technology/products/adf/adffaces/11/doc/dvt/tagdoc/dvt_shapeAttributes.html
It's not the problem to write this backing bean to access the value of attrs.tooltipLed1 but just for my understanding.
Why it's possible to pass a literal string for the property "tag" but not the EL "#{attrs.tooltipLed1}" ?
regards
Peter

Hello Branislav,
attrs is just the parameter interface to the declarative component and contains the parameters tooltipLed1, tooltipLed2, ...
    <af:xmlContent>
      <component xmlns="http://xmlns.oracle.com/adf/faces/rich/component">
        <display-name>ledBar</display-name>
        <component-class>component.LedBar</component-class>
        <attribute>
          <attribute-name>tooltipLed1</attribute-name>
          <attribute-class>java.lang.String</attribute-class>
        </attribute>
        <attribute>
          <attribute-name>tooltipLed2</attribute-name>
          <attribute-class>java.lang.String</attribute-class>
        </attribute>
        <component-extension>
          <component-tag-namespace>component</component-tag-namespace>
          <component-taglib-uri>/tannStandardComponents</component-taglib-uri>
        </component-extension>
      </component>regards
