How to use custom nodes in a JTree without reinventing the wheel?

Hello,
Each node contains two JTextAreas in a Box layout and a few JButtons.
I wish to display these nodes in a JTree.
Reading the tutorial, it seems I would have to reimplement the TreeModel, TreeCellRenderer/Editor, MutableTreeNode interfaces etc.
Can I use the DefaultTreeModel, and other standard widgets (great stuff!) to minimize the amount of reimplementation I must do. aka avoid reinventing the wheel? I was thinking of extending my node from the DefaultMutableTreeNode class - however it does not display the nodes with the TextAreas, buttons etc.
any help appreciated.
thanks,
Anil

was able to fix it over here:

How to use custom API's

Hi All,
In OIM how can i use my own/Custom API"S. Wher do i need to place the Jar/Class files. Like in other Identity Management tools (I only have the experience of SUN) you can place the files under WEB-INF/lib or WEB-INF/classes and then can easily use them, does OIM provides this/similar kind of functionality and how we can use that.

Hi,
If you want to use custom API to create adapter then put the jar file in <OIM_Install>/xellerate/Java Task/
folder and if you want to use them to create task Schedular then put it in <OIM_Install>/xellerate/Schedular/

HOW TO: using custom fonts in native storyboard views from an ANE on iOS

Hey,
In our apps, we have embedded storyboards into an ANE, and successfully used those screens in an AIR app, and figured out how to use custom fonts in those views.
I wrote a quick blog post about it and just thought I'd share it real quick in case it helps someone.

Hi WayHsieh,
>>can I just "install" fonts through Word App? Does Word Apps have enough privilege to install fonts on Windows? Can I just click a button in Word App, and then it will install fonts automatically?<<
Based on my understanding, it is hard to achieve the goal. Because the app webpage is hosted inside an Internet Explorer control which, in turn, is hosted inside an app runtime process that provides security and performance isolation and it is under
low-Integrity level.
Here is the figure for apps for Office runtime environment in Windows-based desktop and tablet clients:
You can get more detail about Privacy and security from links below:

Hope it is helpful.

How do I use a path as an argument without breaking the -classpath option?

How do I use a path as an argument without breaking the -classpath option?
I have the following Korn Shell Script:
#!/bin/ksh
    CSVFILE=/EAIStorageNumbers/v1/0001/weekly05222006.csv
    OUTPUTFILE=/EAIStorageNumbers/v1/0001/08000000.txt
    PAGEMBR=0800F341
    cd /EAIStorageNumbers/v1/bin/
    java -classpath com.dtn.refinedfuels.EAIStorageNumbers $CSVFILE $OUTPUTFILE $PAGEMBRWhen I run the shell script, I return the following error:
Exception in thread "main" java.lang.NoClassDefFoundError: /EAIStorageNumbers/v1/0001/weekly05222006/csv
Thus, the -classpath option sees the first argument as a classpath. When I remove the -classpath option, I get a different error, which is another issue:
Exception in thread "main" java.lang.NoClassDefFoundError: au/com/bytecode/opencsv/CSVReader
at com.dtn.refinedfuels.EAIStorageNumbers.main(Unknown Source)
Thoughts or suggestions on how I can get the -classpath option to work with the defined Korn Shell Script variables would be greatly appreciated.

I think you're misunderstanding the classpath argument. This tells java where to look to find your classes. The argument you're supplying looks like the class that you want java to run. Run something like this: java -classpath $MY_CLASS_DIR my.package.MyClass arg1 arg2 arg3.

I Stupidly have one iCloud account but with two phones using it. How can I delete iCloud from my phone without deleting the account from my husbands phone. He needs the account on his but I dont want it on mine!

But does this delete the whole account from the cloud, or just from my device. I must make sure my husband doesn't loose all his business contacts which are in the iCloud device. Thanks.

Does anyone know how to use pages so you can export pdfs from the internet and automatically drag words from the document into the file name of the pdf (i.e., author, title of a scientific paper)

Does anyone know how to use pages so you can export pdfs from the internet and automatically drag words from the document into the file name of the pdf (i.e., author, title of a scientific paper). For example, if I am downloading a paper by smith called "Surgery" that was published in 2002, it will automatically set the file name in the download to smith- surgery 2002. I have heard pages is smart enough to do this.
thank you

Pages can export only its own documents. They may be exported as PDF, MS Word, RTF or Text files.
Pages can import (ie. Open a file as, or Insert a file into, a Pages document) documents in several formats, but won't rename the document as you describe. Documents that can be Opened (eg. Text, AppleWorks 6 WP, MS Word files) are converted to Pages documents, and retain their original names, with .pages replacing the original file extension. Files that can be Inserted (generally .jpg, .pdf and other image files) become part of the existing Pages file and lose their names.
It may be possible, using AppleScript, to extract the text you want and to Save a Pages file using that text as the filename, but that would depend in part on being able to identify which text is wanted and which is not.
How will the script determine where the author's name begins and where it ends?
How will the script recognize the beginning and of the title, an decide how much of the title to use in the filename?
How will the script recognize the year of publication?
For papers published in a specific journal, with a strict format for placing each of these pieces on information, or containing the needed information as searchable meta data in the file, this might be possible. But it would require knowledge of the structure of these files, and would probably handle only papers published in a specific journal or set of journals.
Outside my field of knowledge, but there are some talented scripters around here who might want to take a closer look.
Best of luck.

Barry

How to use logger to send any output instead of the console?

How to use logger to send any output instead of the console?

How to use logger to send any output instead of the
console?There are three commonly used logger inferfaces, the log4j, the java.util.loging and the Commons logging (which works with either.)
You create a logger object, generally one for each class. Normally a private static variable points to it and it has a name equal to the FQN of the class.
e.g.
package org.widget;
public class MyClass {
private static Logger log = Logger.getLogger("org.widget.MyClass");That's the java.uitil.Logger formula.
Then there are method on the logger to call for various kinds of output. There' are different logging levels, priorities like SEVERE or DEBUG. When running the logs are configured to ignore messages of less than a set priority.
You can also pass an Exception or Error to the logger which will log the stack trace.

Can I back up iPhoto to the cloud via some apple service (iCloud)
No
or do I need to use something else? If so, any recommendations?
An external hard disk:
Most Simple Back Up:
Drag the iPhoto Library from your Pictures Folder to another Disk. This will make a copy on that disk.
Slightly more complex: Use an app that will do incremental back ups. This is a very good way to work. The first time you run the back up the app will make a complete copy of the Library. Thereafter it will update the back up with the changes you have made. That makes subsequent back ups much faster. Many of these apps also have scheduling capabilities: So set it up and it will do the back up automatically.
Example of such apps: Chronosync - but there are many others. Search on MacUpdate or the App Store

How to delete aggreagetd data in a cube without deleting the Aggregates?

Hi Experts,
How to delete aggreagetd data in a cube without deleting the Aggregates?
Regards
Alok Kashyap

Hi,
You can deactivate the aggregate. The data will be deleted but structure will remain.
If you switch off the aggregates it wont be identified by the OLAP processor. report will fetch the data directly from the cube. Switching off the aggreagte won't delete any data,but temporarly the aggregate will not be availbale as if it is not built on the info cube. No reporting is not possible on swtiched off aggregates. The definition of the aggregate is not deleted.
You can temporarily switch off an aggregate to check if you need to use it. An aggregate that is switched off is not used when a query is executed.This aggregate will be having data from the previous load's. If the aggregate is switched off means it wont be available for reporting but data can be rolled up into it.
If u deactivate the aggregates the data will be deleted from the aggregates and the aggregate structure will remain the same.
The system deletes all the data and database tables of an aggregate. The definition of the aggregate is not deleted.
Later when you need those aggregate once again you have to create it from scratch.
Hope this helps.
Thanks,
JituK

Not true at all.
You only buy the right to your own personal use.
You do NOT have the right to distribute to others.
This is illegal. There is no doubt about it
