Enterprise Java-Based Application Development

This company appears to be doing some rather interesting things for Java based enterprise application development. Looks like you can build apps much faster than any traditional method I have seen...can build work flows too.

Not sure if this helps.... ( It only will help if you are some how using Javascript to talk to the applet. )
Macintosh computers do not support "LiveConnect" in any of their browsers. So if you are using Javascript to interact directly with the applet, i.e., to modify properties on the applet itself, then you're out of luck.

Front End for BW 3.5 and Java based application

We are trying to connect two systems; SAP based (through BW) and Non-SAP based (Sybase, Java based) applications. We are exploring BI Java SDK with UDDI or XI services to bring Non-SAP data to NetWeaver. We don't want to store all data from sybase to BW. We could use Front end of BW or any other GUI from SAP Portal. I have heard options like UI, GUI machine, net weaver developer studio, visual composer. Ideally, we would like to combine non-sap and sap data in Business explorer/BW web browser but any other front end suggestion within Net weaver frame work will help us keep our cost down. Please advise.
Thanks.
Vinay Karna

We're in the middle of upgrading from 3.1 SP 22 BW w/6.20 SAPGUI. We've only upgraded a sandbox BW server at this point, but we have upgraded all BW team members with SAPGUI 6.40 FEP 5 and can successfully connect to our 3.5 and 3.1 BWs.

Problem with Java-based application and WebVPN

Hello. Could you please help me in find out any specification/known limitations in using Java-based applications through WebVPN in Cisco ASA 5520 v8.3(2).
A customer of mine has got in trouble in using a Java viewer for graphical files that is invoked by another application (this one correctly served via WebVPN), that cannot be launched because JVM does not find it (NullPointer).
Our suspects are generically about the URL rewriting of the WebVPN and/or unsupported configuration in the ASA SSL certificates vs Java.
Any hint about where to search or what to try?
Thanks.

Embedding java based application in portal

hi ,
I want to embedd a java based application..Iam giving the pageURL in provider file..will it work r any problem..
i want to display that application as portlet.is mentioning page url is enough..that is tomcat..
Second way:if i copy all jsps and source files to htdocs and create a war file and ear file..will it works..
how to mention in provider.xml file to show this application in portal.
is there any specific way..
plz mail me
regards,

Our expirience with these types of applications is that you will need to integrate your jsp files (to some degree) into Oracle's jpdk framework, which essentially means some of the functionality of your jsp files may not work properly unless you switch to use many of JSP files with the JPDK api (i.e. custom tags and custom api calls so that the portal can render your application as a java portlet provider).
I think there is also a way that you can deploy your web application in oc4j and possibly use the web clipping portlet to show this java based application, however, I am not familiar with this, and you should probably ask Oracle Support for more information

Webdynpro Java based application performance testin

Hi Experts,
could any one of you please provide me step by step guide to use some tool which can be used for profiling webdynpro java based application?
this is very urgent...... kindly help
Best regards
Falgun

My recommendations:
- Always use a BufferedInputStream and BufferedOutputStream around the socket streams
- Increase the socket send and receive buffers to at least 32k if you are on a Windows platform where the default is a ridiculous 8k, which hasn't been enough for about 15 years.
- Your 2-second timeout is far too short. Increase it to at least 10 seconds.
- Your strategy of counting up to N short timeouts of S seconds each is completely pointless. Change it to one single timeout of N*S seconds. There is nothing to be gained by the complication you have introduced to this.

What is better way to install java based application?

What installer is better to create stanalone installer package for my java based application?

InstallShield Multi-Platform Edition or Install Anywhere are equally good. They are not cheap though.

Session problem in Enterprise Java / Weblogic application

Background: we are using session variables in our enterprise java application running Weblogic application server.
Issue: When we have more than one browser open in the same PC there is session variable conflict.
Example:
1) Variable v1 of browser b1 has state X.
2) We open browser b2 and run the application, the variable v1 has session Y.
3) We come back to browser b1. We notice that v1 has state Y, we are whereas expecting it to be X.
Question:
How do we maintain the various instances of session variables when using multiple browsers from a single PC?
N.B. But this is not an issue when we check the application from multiple PCs each with a single browser open.

I'm not sure about the ins and outs of the workings of Weblogic sessions, but:
the sessions are probably being kept as cookies. This is probably what is causing the problem. That is why it works from different PCs.
Try changing the session tracking from cookies to URL rewriting, and see if the problem remains. URL rewriting should make the URLs completely independent when run from different browsers.
Let us know how you get on,
Manuel Amago.

Workflow Issue - Enterprise Portal based application not updating Notif.

Hi,
We have designed some workflows based on Adobe Interactive Forms.
We have mapped the APPROVAL STEP to an Enterprise Portal Application(IsrFormApproval) through the SWFVISU txn.
We had a requirement that the Supervisor can change the contents of the Adobe Form during Approval. But when we make these changes to the Adobe form before approval, these changes are not persistent. I mean, when I make changes to the Form, these changes are not getting reflected in further approvals.
Can anyone help me out in these regards.
The notification changes are not getting updated by this IsrFormApproval application.
Regards,
Raja Sekhar

Hi Jocelyn,
Thanks for the reply again.
Yes, I checked my PC has the following ActiveX Controls in place.
1)AcroIEHelper.dll
2)AcroPDF.dll
3)GbDetect.dll
4)Pdfshell.dll
I hope these are the only DLL's that should be there by default.
Is there any specific Configuration to be done to ADOBE DOCUMENT SERVER for this feature to work alone.
Can you let us know where should we mention the TEST OPTION in QISRSCENARIO txn.
Yah,I maintained all the needed parameters as you said.
I cant find any error message in workflow log and flow goes smoothly to the next level supervisor without persisting the changes done by first level supervisor.
So,can you let us know clearly if <b>IsrFormApprove</b> application can really update the NOTIFICATION details at Supervisor Level.
I will check the full cycle if WS50000041 today.
Regards,
Raja Sekhar

Help on java/j2ee application development framework

hello java-gurus,
I'm new to java and is working in java for just 15 months.i want to know more about the platform/framework which is used in the development of java/j2ee projects.To be more specefic i want to build a java/j2ee project .
-->The project will be located in the eclipse workspace.
-->The eclipse will be connected to the cvs and will save the latest code in the repository.
-->The project will have a build.xml file which on being executed
will check the latest code from cvs.
will run j unit test.
on success from the junit it will compile the project.
It will make a .war,.ear etc file..
It will then be deployed in the application server.
So i want to make a framework of this kind.So i want help from u guys how to proceed.
I'm just a starter with ant scripts .know how to clean,build and make war files ..I also know about eclipse like connecting to cvs,generating ant script from it etc..
i'm also comfortable with struts,java,servlet etc..
So do give me some guidelines how to proceed .
thanks

Hello,
i'm working in project same style of what you want. here are details :
- eclipse for development - lomboz plugins for j2ee support.
- using subclipse plugin for svn support checkout and commit, in case of cvs i think it is default in eclipse.
- the framework is Struts, which is a very very powerful J2EE framework.
- eclipse plugin lomboz supports creating and deal with struts project
it also offers GUI for configuring struts xml files.
- lomboz contains plugin for creating and define application servers and containers like tomcat and jboss, so you can compile, run and debug your code from your eclipse.
- i use many other tools for creating UML diagrams and ERD diagram and reflect contents to existing projects.
i think with struts,eclipse and lomboz you need nothing else.

Pasting Image from Mac clipboard to Java Based Application.

Hi,
I am working on "iMac 10.2.7". I need to paste an image from other
application using "Java version 1.4.1". I am trying to retrieve the image
from the system clipboard after it is copied from some other application. I
am pasting the code which illustrates my requirement. It works fine on
windows. But does not work on Mac.
On Mac it does not cross the supported data flavor check
(clipData.isDataFlavorSupported(DataFlavor.imageFlavor) where clipData is
the Transferable object). It seems Mac has some InputStream instead of Image
in the clipboard when some image is copied. I tried to read that InputStream
using ImageIO.read(java.io.InputStream). But that is also returning null.
Thanks

Java web application will not run on iMac.

I have a problem that has defied technical support in 2 organisations.
I am a stock trader and use a high spec iMac for my trading platforms. Recently I tried to run two different trading platforms on my Mac without success. The applications are Thinkorswim from TD Ameritrade and Trader Workstation from Interactive Brokers. I can download the Mac versions of either the web based or standalone versions of these apps and install them ok but when I double click the apps I get a "bouncing" logo appear in the dock and then it disappears. These are Java based applications. I have checked that Java is enabled, latest version etc and that Java web start is in place - but to no avail.
Now the weird part, I also have a Macbook Pro and the apps load OK on this.
Both machines run latest version of Lion, and all parameters and settings for browser, Java, preferences are identical. I cannot find a difference between the two machines.
Can anyone suggest a possible cause and solution? Greatly appreciated.

I had the same - was a un unzipping issue...
If you have a 3rd party zipper - either uninstall or turn off the zip file handing under prefs
only use the built in Lion unzipper.
