Java application built using cr4e(clipse) fails to work in some Windows OSs

I created a variation of the SampleViewerFrameClient, leveraging the opportunity to automatically refresh (refreshReport()) a Crystal report. This worked in Windows 2007, but fails to work in Windows 2008 and 2003 (in a couple of ways).
One theWindows 8 system with Crystal Reports installed, the viewer frame deploys displaying the report selection window, but after selecting and opening a Crystal report, it presents the following error window:
Problem Showing Report
Error Code: -2147467259
This Windows 8 system happens to have both Crystal Reports 2013 and Crystal Reports for Enterprise 4 installed. Java version JDK 7u55.
On the Windows 2003 system, without any Crystal Reports installation, running Java JRE 1.6, it fails with an exception:
unsupported class version error (major.minor 51.0): SampleViewerFrameClient.
It runs fine from eclipse on the Windows 2008 system.
Thanks!

Fixed the unsupported version error (by compiling with appropriate java compiler in Eclipse), and the report launch error in the viewer was resolved as well.

Hi,
We have an application built using HTMl 5 and Javascript running on IPad2, iOS5.1 Safari 5.1.
When a file url is clicked instead of asking for Save or Open or Cancel options, the file gets opened on IPad by default.
Is this default behaviour which cannot be changed or can it be configured to ask user preference?
When we try to download a file(.pvw file -> a model file) in the above application, safari throws "Download failed" error.

Safari on an iPad in general does not allow downloading of files. That's a safety precaution in the iOS SDK to keep unauthorized content off of iOS devices. Safari will open from the web site file types that it can handle, but direct downloading isn't normal behavior, and I don't believe the behavior can be changed, though you can try asking in the developer forum, either here or the one to which you have access as a member of Apple's iOS developer program.

JAVA Application speed using JARs

Good day guys,
I have a quick question about the perfomance.
When I write Java application that uses other third party JARs, do I have to remove all the
classes from those jars that I dont use to make application run faster or it does not metter?
Thank you very much

Thank you very muchLet's take that to another level. Suppose this is on Windows, and that none of the apps running on it will ever use some DLL(s) or some APIs in those DLLs, which are already installed on the box. Do you really think you should worry about trimming them down?
And surely none of the java specific apps you will write will use ALL of the classes and methods in the whole java library, so should you whack those too?

Is it a possible to run Java application built by JBuilder other than it?

Dear All,
I am expecting the quick response from you people.
We have built our EJB application completely using JBuilder 9.
Due to some license problem, there is a delay getting JBuilder original version .
We dont want to waste our time to wait for JBuilder.
So, is it possible to run our EJB application other than JBuilder???
I tried to build the application thru Weblogic8.1, but failed to do so.
Awaiting for your immediate response,
Thank you,

Hi,
I've written build.xml for our application and tried to run thru Ant tool. Unfortunately, it is failed to compile, since there is some mismatch version it seems.
It has thrown some compile time errors as below:

Load sound in java application without use of newAudioClip api.

In personal java 1.2, (JDK1.1.8), the method newAudioClip is unavailable to load sound. What other api can one use to load sound into the java application in this case?

there's nothing wrong with the old one, except that it's a api of the applet. If you try to run the applet thru' the java app. (without the browser or applet viewer), the getaudioclip api will fail.
This is the limitation I am facing, 'cos I am developing in Personal Java1.2 env.

Application developed using JDK1.2.2 not working with JRE1.3

I am supporting and application developed using JDK1.2.2, it uses JDBC drivers from oracle(classes12.zip) to connect to an Oracle 8i database. This application is not working with JRE1.3. Can someone suggest any possible methods to make it work with JRE1.3?
Thanks in advance,
Anoop.

well, Now the problem is partly solved. I was having problems in displaying a frame(derived from JInternalFrame), later I discovered that for JRE1.3, I have to explicitly set the setVisible option to true.
I have a few more frames to correct. I hope after that it wil be alright..
Thanks for the quick response.

Need to Import an application built using Oracle Service Bus on Oracle Public Cloud

I have built an application using Oracle Service Bus (OSB) eclipsed IDE which transfers file from server1 to server2, reads the transferred file, transforms it into a payload and calls a webservice. I have tested this application locally by installing Oracle Service Bus on one on my servers.
I have java as a service account on Oracle Public Cloud. I would like to import the above application onto Oracle Public Cloud. I am not sure if the Weblogic domain on Oracle Public Cloud has enabled OSB or not.
Let me know if someone can help me.

Hello,
Oracle Service Bus is currently not supported in Oracle Java Cloud Service.
Oracle Java Cloud Service supports deployment of JavaEE and ADF applications.

Compatability of running composite application built using CAF

Hi all,
I want to know one basic question about using CAF tool.
Suppose if I use CAF of Netweaver 2004s (Netweaver AS 7.00) to build a composite application, is it possible to deploy the solution to the customer who is having Netweaver AS 620 or 630?
Appreciate your help. Thanks in advance
Regards
Guru

Hi Gurunathan,
That's not really possible. You need to deploy the solution to the same J2EE engine version as NWDS where you built your composite application.
Even SP level must be the same. I recently met the problem that a composite application was built under NWDS 7.0 SP8 and even deployment to 7.0 SP7 J2EE engine was failed because of versions incompatibility!
CAF, J2EE engine and NWDS versions must be the same, it's very important for consistency.
Best regards,
Aliaksei

Commerical adobe air application built using Robohelp - thoughts on software protection

Hello Forum,
I am in the process of building a commerical software application - a niche business methodology (processes, tools, templates) - and for which I naturally want to apply *some* level of protection against unauthorized copying. The two main requirements I have are:
1. That the software package itself cannot be installed any number of times on any number of machines (as is currently the case with the adobe air output for distribution).
2. That large chunks of the content cannot be copied and pasted
Here is where my thoughts are so far:
1. There are a number of third party providers in this space. The ones i have idenftifed so far are: LimeLM, NitroLM, Excel Software's AirLicense and Zarqon. There is also something called Sharify out there but from the site and lack of developer response I think this is now dormant. All of these provide a means of locking down one license to one device but that can be transferred if the user loses and changes their device. Has anyone had any experience of these or other solution providers?
2. As I understand it there is html code that can be added to disable copy and paste. Does anyone know what this is? Does anyone know how to apply it?
Finally: we are a small start up without in-house technical skills. This was a major reason we chose RoboHelp as a solution - it meant that the software could be build by us, the subject matter experts who were creating the content. Does anyone know of a good place to crowd-source the technical skill set required to apply both the solutions to 1 and 2 described above?
We are using RoboHelp 9 with Adobe Air desktop application output.
Thanks in advance for any constructive comments - and best wishes to you and yours for 2013!
Felix

Perhaps it's time to take stock of the requirement, what has been established and your options given where you are.
Requirements
You want protection against multiple installs.
You don't want users to be able to copy and paste the content.
Established
Neither of those are built in to AIR Help.
To build them in you would have to create your own AIR application as the RoboHelp code for creating the AIR installer is locked down. Confirmed by Scott Prentice on HATT.
You do not have an house AIR developer.
Options
Tackling Requirement 1 is going to require a developer to replicate what Adobe have done and add the extra requirement that the installer can only run once.
Given the hours that Adobe put into this and with the resources at their disposal, I have to question the commercial viability of that.
A customer could legitimately need to reinstall, for instance in the case of a hard drive failure.
Perhaps my earlier suggestion of finding someone who can wrap up the AIR file in something that deletes it after installation, thereby preventing a second installation, would be viable. You would need to investigate that and do it in a way the customer can get a fresh download where a further installation is legitimate.
Otherwise I think you need to be looking at a very different approach. Your problem is the same one that Adobe face. You will recall that when you installed RoboHelp you had to activate it. That authorises the use of RoboHelp on a specific machine. The licence authorises installation on a second machine and that has to be activated too. Attempt a third activation and you will get a polite refusal until you deactivate an earlier installation. What you need is a commercial organisation to supply your product in a similar way. The trouble there is your product is not an application in the same way as RoboHelp.
You could use the WebHelp output and apply password protection to your site but again you are going to require development skills. Even then, you are relying on your customers not to reveal the password and that sounds like a No No as you don't trust them not to copy and paste the information.
Copy and paste is difficult to prevent. There are tools for web sites that would likely work in webhelp but you also have to prevent screenshots being permitted. Ultimately, going to state secret espionage levels, how do you prevent someone taking a photo of the screen? It's more about making it difficult to do casually rather than making it impossible. A high brick wall around your house makes entry difficult and deters most from attempting entry, it does not make it impossible.
I am sorry this is all negative but the root problem is your approach was wrong given these requirements. Unless someone else has other ideas, I think you need some commercial consultancy for information on how to get this idea off the ground and that is way beyond what this forum offers. Perhaps you could approach Scott Prentice at http://www.leximation.com for such assistance but I think it would be on a fee paying basis. Scott is a very knowledgeable person in many areas and he is very approachable.

Blog or Wiki applications built using APEX

I have been tasked with finding a ready-made solution that we can use as a developers' scrapbook where development team members can store useful hints/tips, code samples, coding standards etc etc
An APEX solution would be best (something similar to Carl Backstrom's APEX demo app, maybe) since it's familiar territory and it would keep the sys admins happy - but I'm open to other solutions.
A non-APEX solution would have to be Windows based, with no server-side requirements.
I quite like TiddlyWiki (http://www.tiddlywiki.com) but it's not multi-user. There is a 'groupauthoring' plugin for it (http://tiddlywiki.bidix.info/) but it requires use of Ruby scripts on the server.
Online blogs like blogspot would be great, but The Business wants to keep everything in-house.
So, has anyone built a blog or wiki-type application using APEX that they would be willing to release 'into the wild'? Or is there another solution that I've missed ...
Cheers
Richard

Hello,
Here is an example of the beginnings of the wiki application, to edit add a subject just login it uses open credentials,
http://apex.oracle.com/pls/otn/f?p=2757:709
the code as it stands here can be downloaded here (it differs slightly from the demo version as i've actually done some dev work on it)
http://oracle-apex.svn.sourceforge.net/viewvc/oracle-apex/wiki/
Feel free to download add critic etc, I defiantly am still looking for someone that knows regex really well it would help greatly speed development along.
There will be movement on this and the forum application as I finally have a bit of time to work on these again, of course anyone that wants to help is greatly appreciated.

AIR runtime and AIR applications built using Captive Runtime still need Admin Privilege to Install

I am working on a small project to install AIR application(native .exe & .dmg) with AIR runtime without needing the Administrator privilege so I used Captive runtime but the installation is still asking for admin privilege
I bundled AIR application with AIR runtime using Captive runtime from flash builder 4.6, then I packaged this into a .MSI using Advanced Installer. Now when I install it for a user without admin privilege it prompts me for Admin credentials.
Can you please tell me if
1. I need AIR distribution license to install AIR runtime without Admin privilege
2. Do I need a different installer
3. Am I missing any step here
Thank you

If you're installing to a location where Windows requires elevated privileges, like Program Files, you'll need to have admin privileges to continue. Are you using an AIR based native installer or have you taken the application with the captive runtime and rolled this up in your own installer?
Here's a section from the Installation and deployment options in Adobe AIR 3 article that might help:
Installation privileges
When designing an installer, one has the option to choose from approaches that may or may not require administrative privilege. For example, a drag-and-drop install on Mac OS X requires no special privilege; users can always copy the application into their own application folders, for which they have the necessary permissions. On the other hand, if registry keys must be written to the machine-specific portion of the registry on Windows, installation of that application will require administrative privilege to do so.
The two installer formats directly supported by AIR, AIR files and native installers, have always required administrative privilege. This was a design decision made in part to simplify the implementation of the AIR installers: If administrative privilege is assumed to be available, implementation is possible if the registry can be written to, and so on. It was also selected because, in many enterprises, this is the desired behavior: administrators can use the privilege requirement to gate software installation.
All the same, there are scenarios where supporting installation without requiring administrative privileges is desirable, or even necessary. This can now be achieved using custom installers; you simply need to author an installer that operates correctly with only standard user privilege. In practice this can be easy to achieve; a simple install-by-copy to a writable location (that is, in the user's own folder) will suffice. Should you author a more complex installer, you should keep in mind that the addition of certain operations during the install process will in turn reintroduce the requirement for administrative privileges.

Use of DSC causes other applications that use SQL: to fail to run.

The use of Labview DSC seems to cause programs that use other vendor's SQL support to lock up and die. My current choice had been to run msconfig to disable loading any labview support upon startup. This allows me to use other applications such as PageManager. However oncde I run Labview I must again reboot to gain access to the other applications.
I thought all SQL and Database drivers were downwards compatible.

Hi,
maybe you should write your question to the NI LV DSC forum directly. It's
not so crowded and suits well for bug reports. I'd suggest to add this to
the discussion "What issues have you run into when upgrading to LabVIEW 7
Express?" ( http://tinyurl.com/xc1c ) even.
Sometimes I've the impression NI needs more pressure of the users for LV
