How to grab global shortcuts keys in a java application?

Hi!
Does anybody know if it's possible to get the focus to a Java application, when it is not selected, using a keyboard shortcut key?
I've written a java application that provides shortcuts keys (like CTRL-M...) for accessing to some operations. For using those keys combinations my application has to be focused between the other opened applications on the operating system (Linux 7.3), as it should be in a normal behaviour... but, I would need that the operation associated to the shortcut key could be executed even if another application had the focus...
Is it possible? How this could be done?
Thanks in advance four your interest and your answers.

Unfortunately shortcuts will work only if your app is focused.

Raynman was asking about what desktop environment you use in archlinux. It is clear what you want to do, but the answer to your question depends on which Desktop Environment (like Gnome, KDE, XFCE, etc) or Window Manager you are using.

Using PhotoShop CS4, How to disable 'Universal Shortcut Keys'?

Hello all.
I discovered in the latest OS, I am not able to customize my Action Shortcut Keys inside Adobe Photoshop CS4 because the "Universal Shortcut Keys" were "in the way"...; I used to able to do this with CS3 and Tiger.
Let me illustrate:
- In the new OS and the new keyboards: F1 is the Brightness Adjustment (Dimmer), and F4 is Dashboard (Launch)
- In the older OS and CS3, I was able to create within, Action Shortcut Keys so that F1 I can create a Layer Mask and F4 I can delete a layer
- In the new environment, whenever I press the F keys, the 'Universal Shortcuts' take priority.
*How do I disable these Universal Shortcuts so that I can create customize shortcut keys?*
Thanks and cheers

Hi
Thanks for the reply! Yeap this is what I am looking for, but unfortunately, or rather, I wish I can still have control over the volume keys somehow, because we work in an open environment, and sometimes we use headphones, sometimes we unplug to let our supervisor see and hear the work (by the way I am in the motion graphics business) So we constantly have to control the volume of the speakers.
Well, I'll just have to put the Sound Control on the Menu Bar
Thanks and cheers

How to create a shortcut key for email ?

You do not say what OS X you are running. If it is 10.8.3 you simply can have Mail a 4-finger swipe away.
No short key neccessary?
If some earlier OS X see >System Preferences>Keyboard>KeyboardShortcuts>ApplicationsShortcuts

Adobe Captivate 8 - How to Assign Custom Shortcut Key

I want to switch between the Film Strip view and the Master Slide view quickly. To show/hide the Film Strip there is a default shortcut key CTRL+ALT+B. For the Master Slide there is none.
Is there a way to assign a custom shortcut key to toggle Master Slide view?

I wonder why the lack of support for custom shortcuts keys does NOT surprise me. In overall, shortcut keys are typical and always required in expert applications.
Anyway, thanks for the tip. I noticed that keeping a number of panels ON slows down the performance so toggling between them ad-hoc might mitigate users frustration.
Again...fruit for thought.

HT4614 How can I define shortcut keys to run apps, files and folders, OS X?

Hi
It could make work so fast by using shortcut keys
For example using "option + command + Control+P" to go to "picture" folder.
but cant do it in Mountain Lion
is there any way to do that?
Thank you!
Safa

To define keyboard shortcuts use the keyboard Preferences > Shortcuts panel in the Preferences.
Create an Automatotor service, to open the folder you want,
Install that service in your User Library "Services" folder (for example named "OpenPicturesFolder)
Then bind that service to the keycombination you want.
A simple service to open the "Pictures" folder could look like this:
First, an action "Get Specified Finder Items" to select the "Pictures" folder,
Then "Open Finder Items" to open that folder.
You do not need to create a service, if there are already menu commands that do what yu want. Then simply bind the menu command to the key combination.
Good Luck

How to change heap memory size for general java applications (not applets)

Hi. I made a java class which manipulates images and I sometimes get an out of memory error when the files are large. In these cases I can run it successfully from the command line using:
java -Xms32m -Xmx128m myappbut as I run this class from a firefox extension, I can't use this technique.
Could some one tell me how to set this globally? I've found a lot of info on setting it for applets in the control panel but that's it. I also tried editing my deployment.properties file by adding:
deployment.javapi.jre.1.6.0_11-b03.args=-Xmx128mbut none of these options seem to work.
Thanks for any help.

Also you can use use [JAVA_TOOL_OPTIONS|http://java.sun.com/j2se/1.5.0/docs/guide/jvmti/jvmti.html#tooloptions], with more documentation here. JAVA_TOOLS_OPTIONS is available since 1.5. There is no direct documentation on [_JAVA_OPTIONS|http://java.sun.com/j2se/1.5.0/docs/guide/2d/flags.html] but was made available since at least 1.3.
The recent existing forum thread [Java Programming - How to change the default memory limits for java.|http://forums.sun.com/thread.jspa?threadID=5368323&messageID=10615245&start=36] has a long discussion on the issue.
You specified you are not using applets, but if you do, I would also suggest you use the next Generation Plug-in (since 1.6.0_10) that allows you specify the max memory in the applet without having to instruct the user how to make the change. See [JAVA_ARGUMENTS|https://jdk6.dev.java.net/plugin2/#JAVA_ARGUMENTS] for applets. Java Webstart uses resources.

Sending public key to not java application

Hi,
I'm trying to send through a socket connection a public key encoded on X.509 standard, but the key.getEncoded() method returns a array of bytes,How can I convert this array of bytes to a sequence of characters that can be readable by any not java application???Is possible to make this public key readable for any not java application??How can I do that??
How can I send the public key to a not java application??
Thanks.

Thanks for helping, but if I use Base64 encoding does the client have to use a base64 decoder before having to use the public key??
The major problem is that my client is a perl application that uses openSSL, I think it will not understand the key if I send it in Base64(the perl application uses a openSSL API to make the received public key in X.509 back to public key)...

MSS ECM - how to retrieve custom OADP column in Webdynpro java application

Great day to all,
We have created custom OADP column for MSS ECM planning in SPRO.
In Portal, ECM Plan Table, the column is visible. User enters values into that and toggles the tabstrip.
Before submitting, i need to capture that value in Webdynpro java.
My Question is,
How can i make use of that column in my ECM Application using webdynpro java??
or how can i retrieve the custom OADP columns in webdynpro java with out using RFC??
Need ur great help... thanks alot in advance...
Thanks
Malla

In OADP ,there are two types of columns , functional column which cannot be edited in web dynpro java application and another type is application column which can be edited in application and the value of this column is handled in application using rfc enabled function module. MSS ECM comes with certain application column whose values are handled in MSS-ECM application . If you are trying to add custom application column you will have to handle that column value in your Z function module and also at OADP level you should not configure supply function for that column.
In order to call custom Z function module to handle custom application column I would suggest to create a seperate Software component and development component and in that handle the logic for calling Z Function module. Also you will have to define the usage of custom Development component in the MES-ECM standard component.

How Can I submit data to an external java application

Hi Gurus,
I've this requirement and I would appreciate if someone can provide me some guidance.
My requirement is that we are building a webdynpro ABAP application inside our SAP system. This webdynpro application should be able to collect data from the user. When the user submits the data, this data needs to be processed by should an external java application for which we've the URL available.
The data has to be sent to this external Java web application in the form of parameters to that application programatically through post method.
Is there anyway we can code this in our webdynpro ABAP application.
Please help.
Regards,
Sam K

It isn't Web Dynpro ABAP functionality - per say - but you can use the class CL_HTTP_CLIENT for the ABAP server to act as a browser and make HTTP requests to other web servers. This is how Web Services work from ABAP. This class lets you build the request object and post it to an external server. However you might consider if using a full blow Web Service might provide you with a better approach than just posting to an external URL.

How can I measure memory allocation of a Java Application?

We built a web application that enables images to be loaded into a database through a servlet running on Tomcat. We have inconsistent behaivor when more than x number of people are loading images simultaneously. No doubt a memory allocation problem, but how can I measure it?
For example, I'd like to be able to create a graph showing the resources used against the number of people making uploads. I am using Linux and Tomcat/Apache.
I am hoping for something like Memory counters that are available for measurine Windows applications on MS Windows - comes with the Resource Kit. Does this type of tool exist for the Java/Linux market?

It is difficult to gauge memory usage from a Java application as the JVM handles garbage collection and even if objects are not referenced they might still be sitting in memory until the next garbage collect.
Anyhow, a way to query available memory is:
Runtime.getRuntime().freeMemory()
You can run this at the begining of a process and at the end and examine the difference. You should call System.gc() before each freeMemory() call in order to try to force garbage collection.
Another method would be to turn to the underlying OS. On linux you could use 'top' or 'ps'. With ps you could do something like:
ps -o rss,vsz,%mem <pid>
Where <pid> is the parent Tomcat process' id. The resulting three columns are:
- Amount of real memory used.
- Amount of virtual memory used.
- Percentage of real memory used.
'man ps' wil give you more options on how to use ps.
There are also fancy graphical stuff like 'gtop' as well.
Hope this helps.
