Accessibility of Workshop 8.1.6

Hello,
I tried sending this to an email address ([email protected]) as suggested by some documentation, but the address is dead. I'm posting it here in hopes of getting more info on the accessibility of Workshop for blind developers.
Hello,
I want to start by saying "thanks" for working to make the various BEA products accessible to the blind community.Â I am a blind developer specializing
in application integration, and am finding myself less and less able to operate in this field as time goes on due to the increasingly graphical nature
of design and development activities.Â One particular integration company, who shall remain nameless (Tibco), has done little if anything in this regard.Â
I'm using the newest Workshop - 8.1.6 - and the newest version of Jaws for Windows - 7.1.0.Â I have 2 basic questions.Â First, your documentation states
that blind users prefer to use source view over design view when creating applications in Workshop.Â The docs don't really say 'how' to do that as far
as I can tell.Â For example, I'm going through the tutorial called "Creating Your First Business Process."Â After deleting RequestQuote.jpd and related
files, I'm asked to create a new file with the same name.Â No problems so far.Â Then the doc says to double-click on the empty Starting Event target, which
allows me to make some selections.Â At this point, I believe I should be performing this step in the source view.Â I can open the source view, but what
steps do I take once source view is open?Â I'm sure that if I add the right code, the design view will be updated with the changes, and all will be happiness.Â
Are there docs that describe how to interact with a jpd and its various nodes using only the source view?Â
My second question is related to this statement in your documentation:
Recommended Assistive Technology ConfigurationÂ
BEA provides certain recommended configuration options for industry leading assistive technologies. These configuration options ensure that the accessibility
enhancements present in the application are available to the assistive technology user. Configuration options are currently available for the JAWSTM screen
reader produced by Freedom Scientific, Inc. Other assistive technology configuration options are available on request from BEA.Â
What sort of configurations are you referring to?Â Where can I get these configurations?Â
Thanks again -Â
Brian.Â Â

Hello Brain,
I have contacted the internal alias to find why the [email protected] alias isn't working for you.
Regarding the specific question, I have not been able to find a way to achieve the same results in the source view as what the "double-click on the empty Starting Event target" does.
I can send you specific snippets of code which gets generated for each choice, but unfortunately, there are certain parts of this code which are auto created and should not be edited by the user.
In my experience with WLI processes, I've noticed that certain operations are restricted to just the design view.
I'll go ahead and create an internal CR to track this.
Regarding the second question, I was able to find the documentation you are referring to, but unfortunately I do not have much information regarding the specific configurations. I'll try to get some clarification and get back to you.
It might help to post this question to the process news group at http://newsgroups.bea.com/bea/forum.jspa?forumID=2047
cheers

Default namespace in WebLogic Workshop generated WSDL

Hello there,
I am trying to access a very simple webservice developed in WebLogic Workshop
(say something like HelloWorld.jws) from a ColdFusion application. However, I
get an Axis fault on Coldfusion implying that it could not invoke the required
method. I am running the examples server and the work shop. I noticed that some
of the documentation mention changing the namespace from http://www.openuri.com
to something else.
Does that have to do anything with the service not being able to be invoked or
it could be something else?

Sanjeev,
The exception you mentioned about changing the namespace should not cause
the behavior that you are noticing.
The exception that you are receiving states that your ColdFusion application
is not able to access the Workshop Web Service.
Are both coldfusion and Workshop on the same physical machine ?
If they are not on the same machine.
Are you able to access the wsdl via a browser from the machine on which
coldfusion installed ?
The wsdl has an service name tag
- <port name="SimpleTestSoap" binding="s0:SimpleTestSoap">
<soap:address location=http://localhost:7001/Raj/SimpleTest.jws />
</port>
This address location is be default the machine on which this Web Service is
built, and this defaults to localhost:7001.
This entry can be modified by editing the weblogic-jws-config.xml file found
in the WEB-INF/lib folder of the project.
Can you make sure that address location contains the correct address and
also check to see if the Web Service is available via any browser.
Hope this help.
Thanks

Can not browse catalog when triying to create a discount in workshop 8.1

Hi,
I am using weblogic portal 8.1 and triying to create a discount. I followed the
instructions that are found in workshop help named as "using commerce" and "creating
discounts".
I have installed commerce services and commerce taglibs. I tried to create a discount
but when I try to use wizard to configure my discount I can not browse catolog.
I click on "wizard" and select "simple discount" from the appeared window but
then I can not browse the porduct that the discount will be applied to.

Before I forget, make sure the server is running and that your
application deployed correctly (look in the console
http://locahost:7001/console). Verify that the toolSupport.war module's
context-path is <appname>Tool, where <appname> is the name of your
application (e.g. portalAppTool). Verify that you can access the URL
http://<hostname>:<port>/<appname>Tool/CatalogWS, where <hostname> is
the name of the machine the server is running on (probably localhost),
<port> is the port WLS is listening to (probably 7001). So, for
sampleportal, you would use
http://localhost:7001/portalAppTool/CatalogWS. Use your server's admin
username/password (e.g. weblogic/weblogic for samples/domains/portal).
You should get a webservice test page. That's the URL that workshop
tries to access to get catalog information; so, if you can't access it,
workshop can't either.
If that works, I actually need output from running workshop. It looks
like that might not actually go to bea/weblogic81/workshop/workshop.log.
If you're on windows, can you temporarily modify
bea/weblogic81/workshop/Workshop.cfg so that the second line, which
should look like:
C:\bea\jdk141_03\jre\bin\javaw.exe
uses java.exe instead, as in:
C:\bea\jdk141_03\jre\bin\java.exe
On Unix/Linux, modify Workshop.sh so that it doesn't redirect output to
/dev/null.
Then, in bea/weblogic81/workshop, create a file called debug.properties
that looks like:
usePackageNames: true
com.bea.portal.ide.rules.server: on
Then, run Workshop.exe/Workshop.sh. A command window should appear with
some output like:
DEBUG: extensions=C:\bea\weblogic81\workshop\extensions
INFO: Registering extension com.bea.portal.ide.CommonServices
INFO: Service com.bea.portal.ide.findrefs.FindRefsSvc registered
INFO: Handler for urn:com-bea-portal-ide:ref-finders registered
In Workshop, try to open the catalog browser from the discount. You
should get a bunch of output in the command window. Send that here.

Birce -
Do you get an error dialog, or does the catalog browser open without
anything in it?
If you get an error dialog, can you attach your workshop.log file? It
should contain an error message and possibly a stacktrace about the
catalog browser.

How to Install/Access HANA Academy Workshop Exercise Solutions and Templates

In Thomas Jung's HANA Academy tutorial on "Native Development Workshop", solutions and templates are cited in the "Simple "Hello World"" video...
HANA Academy - HANA Native Development Workshop: Simple &quot;Hello World&quot; - YouTube
Where are there intructions on where to access and/or how to install/import these workshop resources?
Thank you.

Thanks Thomas.
I've been provided with a departmental, on-premise instance for the purposes of demo and educational sandbox, so will not be using a Developer Edition via one of the cloud providers.
I'm searching for a tutorial path that has kept prerequisite configuration to a minimum.
At first glance, your native HANA development HANA Academy series seems to fit that bill.
In that these are the first hours of my exposure to HANA, I'd love to be able to keep pace with your videos step-by-step. I'd prefer to use the solutions and templates that you begin to use in the second video (Hello World) of that series. As a noob, avoiding the translation from the SHINE doc would preserve my train of thought and prevent me from going into the weeds by taking missteps due to the translation.
Is there a way to access the solutions/templates depicted in your video series other than having to install/use/access Developer Edition?
...or is there another, more recent video tutorial with a close matching set of solutions/templates that you would recommend?
Thank you.

Restrict access to Query Builder component in SQL Workshop

Hello folks,
Can someone tell me if it is possible for an end-user to have access to the Query Builder component only?
End-users on our site are currently using the stand alone version of the old Query Builder (OBE60.EXE), which is not supported any longer, and have compatibility issues when used against a 10g database.
I'm looking for an alternative (query-only) tool, and came across the Query Builder component in Oracle Application Express. But couldn't find anything there that would allow me to limit access to this component for an end-user.
Please let me know if this can be achieved, and if not, is anyone aware of an equivalent tool that would do the job?
Many Thanks,
Praveen

Hello,
No, that functionality does not exist currently, you would need to build your own.
If you search this forum there are a few threads which detail how you can install the Application Builder and SQL Workshop applications into the APEX environment itself so you can see how they (meaning the Oracle team) have built those apps.
Hope this helps,
John.

Slow response and access of Weblogic Portal Workshop 8.1 sp3

Hi All,
Environement : Weblogic Portal 8.1 sp3
Weblogic Portal Workshop 8.1 sp3
Windows XP
Problem:
When the application initially opens up in Weblogic Portal Workshop , the scanning takes too much time.At that time CPU usage is almost 100% with only Weblogic Portal Workshop running. Our application has a webapplication module whose build also takes almost 20 mins. After a build , the workshop hangs with 'Out of memory' error.
Size of our application is almost 200 MB (source code with library files). The application also uses almost 60 .JCS and .JCX files.
Solutions we tried.
1. The RAM memory was upgraded to 2GB with a processor speed of 3.3 GHz
2. We have updated the workshop.cfg with the parameter of -XX:-UseThreadPriorities -Xmx768m
Thanks a lot in advance

We have had some of the same problems with our 8.1.3 portal. The performance is terrible in Workshop.
Unfortunally i dont have that much more advice then that you could try to split your application into several projects to reduce the strain on Workshop and hopefully reduce the build time.

SQL Report not showing data - available in SQL Workshop and SQL Developer

I am having an issue with developing a SQL Report in APEX 3.2.1. I run the code in both SQL developer and SQL Workshop and I get data pulled back (both against my development environment). When I run the same code in a SQL Report region, it returns no data available. Does anyone have any idea what would be causing this? Other regions on the page accessing different tables in the same schema return data without issue. Any help would be appreciated.
Thanks
Freddie

Could you explain the last comment a bit more. Here is a bit more info just in case I touch on the info with it. The db schema is BPAMGR, the Workspace is BPAMGR. We use the same schema for all of our reporting. All of our tables are in the same schema. We don't use any tables outside of this schema. Our APEX workspace has been associated to only this schema. The tables are able to be queried by SQL Workshop in the same APEX instance that the report application is under.

Questions, Suggestions, Bugs - results from 7-day workshop

Last week we (AMIS that is) finished yet another JHeadstart workshop with one of our customers development teams. In this workshop we focused on Struts, BC4J and both JSP and UIX. (so no Toplink this time). By the way: we used JHeadstart 9.0.4.5 in conjunction with JDeveloper 9.0.4.
Over the course of this 7 day workshop we had several discussions, most of these the result of our customers ambition to generate all or most of an application they had already developed manually using the Web PL/SQL Toolkit and integrated with Oracle Portal. These discussions resulted in several questions/suggestions/enhancements requests. I list them below to inspire future releases.
Questions:
·     Why does JHeadstart not make use of the UIX-Struts integration (see Chapter 15 of the UIX developers Guide)?
·     How do you specify which columns/attributes in a Table Layout are sortable?
Suggestion/Enhancement Requests:
·     Offer the possibility to generate Regions Side by side instead of always below each other
·     Could you provide the same kind of nested navigation on persistentAttribute for BC4J as you offer for Toplink, e.g. through the use of Jakarta Commons BeanUtils in DataObjectImpl.getAttribute()?
·     Allow Master-Detail with Detail Table-Form layout style and same page is true (at least a recipe, preferably full generation) (I do understand that having multiple Child-table-layouts with Details-buttons on the same Master-page could be an issue due to the conflicting details-events, but surely one can be arranged?)
·     Generation of breadcrumbs for JSP
·     Allow us to specify for a file upload which attribute will hold the filename; allow us to specify for download which attribute will provide the filename (for the save as dialog in the browser) and possibly the mime-type.
·     Allow an Alt-text property to be defined for attributes with Display Type = Image; this alt-text property can refer to another attribute.
·     In Jsp: Display Type displayField should generate a <bean:write> instead of a disabled <html:text> field. For domain-based attributes that are normally rendered using a pop-list (Choice), a displayField requires additional logic to display (bean:write) the meaning rather than the value
·     Allow the prompt to be empty (if you leave the prompt property empty, the generator will use the attribute name; you can not explictly leave it empy; the workaround is to type a single space for the prompt)
·     Provide a way to preview the defaults that the generator will use for properties that are not explicity set OR provide a way to explicitly set those defaults as values on the Entity Objects attributes
·     Allow the Domain and Region-properties to be set through a Combo-box with a list of the available Domains and Regions
·     Make the private members in oracle.jheadstart.model.bc4j.handler.DataObjectImpl protected, so that a subclass can access those variables
·     Allow us to specify a split prompt , for example Weight|kg that would display as Weight . (field) kg; make the JDG pick up split prompt from Designer and set accordingly in the VO Attribute.
·     Allow the definition and generation of separate prompt and hint values for Find, Table and Form-page
·     Provide a utility to copy VO Attribute properties between ViewObjects (or even to copy entire ViewObjects)
·     Documentation: provide a JDG Reference to-from in addition to from-to: it is very convenient when trying to generate an application using the JDG if you can easily find out what you have to do set in Oracle Designer in order to achieve some result in the generated application. For example: how do I generate a Table-Form layoutstyle?
·     Provide a shortcut to run the JDG again, with the exact same settings as the previous run; this makes incremental development using the JDG a lot more convenient; having to walk through the entire wizard for every little change in Designer is rather a pain.
·     Provide properties in the Group, Lookup and Region elements in the Application Structure File (editor) for recording post-generation changes
·     Generate Regions (minus Table Summary items) in Detail Disclosure
·     Provide (style)Class property on ViewObject Attributes and generate the styleClass property for UIX elements or a class property for JSPs (if the Struts tags do not cater for a Class property, you can also generate a <SPAN class=> around the JSP items)
·     Provide a shortDesc or altText property for VO Attributes; these are turned into popup texts on items and can for example provide popup hints in a Table Layout; generate the UIX shortDesc property.
·     Provide preComment and postComment properties on VO Attributes, Groups and Regions; the values of these properties should be generated into the UIX or JSP pages as  and . Not only does this allow better documentation of the generated sources, it also provides hooks for post-generation utilities.
·     Support displayType numberField/numberItem; this in UIX would render a right-aligned input-item
·     Allow specification of dateFormat at VO Attribute level (in addition to Service Element)
·     Switch to JSTL from the Struts tags at least for bean:write (c:out) and all logic tags; configure new JHeadstart projects for JSTL (libraries, taglibs, web.xml etc.)
·     Allow multiple values to be returned from a List of Values
·     Allow an onBlur property on VO Attributes; this property includes a piece of JavaScript to be executed on leaving the item; the code may refer to other items in the same record. Ideally also provide other event-triggers such as onFocus, onMouseOver etc.
Bugs?? We ran into some issues that may indicate bugs
·     The Master-context in UIX pages for Detail Group, Table-Form (same page false) is missing
·     Master context in JSP voor Detail Group, Form page (same page false) is missing
Watch this Topic    Copyright 2004, Oracle Corporation. All rights reserved. About OTN I Contact Us I About Oracle I Legal Notices and Terms of Use I ·     A ViewObject Attribute with displayType File Upload seems to result in a html:file element that pastes the contents of the file into the HTML Page: <input type="file" name="PublisherLogo" maxlength="100" size="30" value="ÿØÿà JFIF H H ÿÛ C ? $.' ",# (7),01444'9=82<.342ÿÛ C etc It would seem that the value attribute of the <html:file> element should explicitly be set to an empty string
·     (I am not absolutely certain that this is really the case, but we have seen this behavior several times) The JDG seems to generate a faulty BC4J Design for JDeveloper 9.0.4: when running the JDG for the second time for a Module, a second, similar ViewLink is created where the JDG should overwrite a previously created one. In the BC4J Tester we could still see the data, but in the generated application, we could not find the children of the masters through this duplicated ViewLink. Removing the second viewlink did not solve the problem. Creating the ViewObjects and ViewLinks from scratch in Jdeveloper (i.e. not through the JDG) worked fine.

In the meantime, I can answer to your questions:
· Why does JHeadstart not make use of the UIX-Struts integration (see Chapter 15 of the UIX developers Guide)?This has been done to allow the same page to be run both with Struts and MVC Framework, without needing to change the page. Using the UIX-Struts integration would have made the pages 'controller aware'.
· How do you specify which columns/attributes in a Table Layout are sortable?As far as generation is concerned, you can only specify the whole table to be sortable. In case of UIX you can post-gen modify the <sortableHeader> tag of each column separately. In case of JSP you can remove the <a href> tag for each column that you do not want to sort on.

Report in Crystal CRXI using Workshop class datasource

I am trying to create a report using Crystal Reports XI that uses a Workshop class as a datasource. The documentation for V10 and XI says that any compiled java class that has a public method returning a java.sql.ResultSet object can be used as a data source.
I followed an example in the Crystal documentation that uses a bean compiled outside of Workshop and it works fine. When I try to point the config file to my Workshop classes, it does not list any of my class files. Has anybody successfully done this?

Hi Sudhir,
For Building up a connection for OLEDB we need :
In order for Crystal Reports to connect to a database through OLE DB, there are some requirements that must be met:
u2022     The database client software must be installed on the client machine.
u2022     The client machine must be able to connect to the server from its client software
u2022     The client softwareu2019s working directory (example. c:\orant\bin) must be in the Windows search path
u2022     The OLE DB provider must be installed on the local machine.
We have the connection for crystal reports through OLEDB :
The process by which Crystal Reports access data from an OLE DB data source consists of these five layers:
Crystal Reports Layer
OLE DB Translation Layer
OLE DB Layer
DBMS Translation (OLE DB provider) Layer
Database Layer
The data translation is similar to the ODBC connection model. Crystal Reports uses CRDB_ADO.DLL to communicate to the OLE DB provider, which communicates to the database. Crystal Reports can connect to any database as long as that database has an OLE DB provider.
When creating a new report in Crystal Reports, OLE DB data sources are found in the Create New Connection folder with the OLE DB (ADO) connection.
Regards,
Naveen.

Using Creative Cloud on a desktop in a rural area with no Internet access

I have a Creative Cloud subscription for my home desktop. I will soon be participating in a photography workshop in a rural area with NO INTERNET ACCESS. I don't own a laptop and will be hauling my desktop to the place we're staying. I know the software is installed on the machine and I should be fine with using it without online access, correct? Am I also correct in thinking it won't be "seen" as being used on a second computer because while I use it on this trip I won't have Internet access and therefore no IP address?

Hi there
The only thing that might cause you trouble is if your workshop is over a month long. While using applications downloaded from Creative Cloud, internet access is required once a month for a routine license check. Here's a snipet from the Creative Cloud FAQ:
http://www.adobe.com/products/creativecloud/faq.html
Do I need ongoing Internet access to use my Creative Suite applications?
Because your Creative Suite applications are installed directly on your computer, you will not need an ongoing Internet connection to use them on a daily basis. However, you will need to be online when you install and license your software, and at least once every 30 days thereafter. The software will alert you when you need to connect to the Internet for a license status check.
A quick note: if the product is unable to verify your license at the 30 day mark, a 7-day grace period will begin. However, if you are not able to access internet within those 7 days, your applications will be blocked (Soucre: http://forums.adobe.com/message/4513667#4513667)
Regarding your second question - as long as you are using the same device you already have your applications installed on, you'll still only have one device registered to your account.
If you have any more questions, please don't hesitate to post here again.
Cheers!

Web Service over SSL failing in BEA Workshop

I have deployed a web service on weblogic 9.2
I have enabled one-way ssl on it. got a trial ssl certificate from verisign. installed them on the keystore/truststore on the server as well as the jre (cacerts and jssecacerts truststores) being used by the client. the client is on different machine than the server.
i have developed the service through 'bea weblogic workshop 9.2' now when i try to test the service through the 'web services explorer' within bea weblogic workshop i receive the following error:
IWAB0135E An unexpected error has occurred.
IOException
sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
on server:
<Jul 13, 2009 6:45:44 PM EDT> <Warning> <Security> <BEA-090485> <CERTIFICATE_UNKNOWN alert was received from yunus.l1id.local - 10.10.2.72. The peer has an unspecified issue with the certificate. SSL debug tracing should be enabled on the peer to determine what the issue is.>
if i try to access the web service (over ssl) through the browser (ie/firefox), it works fine. i have generated a proxy class to access this web service through the same bea workshop and that works fine too. certificates are identified and all. i also created a small .net (c#) application that calls this secure web service over ssl from another machine and it works fine too!
of course non-secure url for the web service is working fine in every case.
what can be the reason for this failing only in 'web services explorer' in bea workshop?

Hello,
I used this example, when I made my experiments with SSL and Glassfish (GF):
