Netbeans and Corba

Is Corba still around or is Java EE the new standard in distributed apps?
I'm wanting to implement Corba in a solution where a web application communicates via Corba with a server application. The server application performs caching and data retrieval. I'm having trouble finding where to download the neccessary tools to develop a Corba app and if there's a Netbeans plugin.
In older versions of Netbeans, one can enable RMI and Corba distributed application but I can't find the option in versions 6.8 and 6.9.
Thanks.

Yeah it was a multi-question post. I forgot Java EE runs over Corba. I thought about web services in my app but since the front end is a web app already, I didn't see the reason to go that route. What I wanted to do was run a standard Java application in the background on the server that processes csv, processes new database entries, etc. The web application would call upon this Java app for data. The Java app would retrieve it from a cache and spit it back to the web app. If data wasn't in the cache, it would continue in the background processing data for the cache after the data has been passed back to the web app.
Maybe there's a way to have such an app run within the web container that I'm not aware of? I'm using Tomcat.
Oh wait! What if I created the standard app as a web services app and have the web application just call it? but then can the web services app monitor for csv file updates?

Communication problem between NetBeans and Tomcat

hi!
i got a quite mysterious problem. here is what happens:
- i start NetBeans 5.5.1 (the first time)
- i want to debug my JSF-Project, the Debugger starts
- After a few seconds the debugger waits for tomcat (it sais: "Waiting for Tomcat...") and tomcat starts
- Again after a few seconds the tomcat-debugger-output sais "Tomcat startet in 3333 ms".
okay.
when i enter http://localhost:8084/ in my browser i get the tomcat homepage, so the server has definitely started! But nothing happens in NetBeans and nothing happens with my project....
In the lower-right corner i see this blue working-bar that sais "deploying project" but nothing happens. The Project-Debugger-Output still sais "Waiting for Tomcat..." but nothing happens...
And after something around 3 minutes (i guess it's a timeout) i get the error "Starting of Tomcat failed." But is HAS started, i can login to the Administration-Area in my browser!
so i guess there is a communication problem between netbeans an tomcat. Netbeans waits for a message from tomcat but tomcat doesn't send it..or netbeans doesn't understand it.
But the story goes on:
When i press the debug-button a second time it takes only a few seconds till i get the message: "Tomcat server port 8084 already in use". OF COURSE! Because Tomcat has already startet and can't be stoped by NetBeans.
i'm trying to solve this problem for 4 days now, so i would be very happy if anyone has an idea where to start/continue the search...
thanks,
flo.

Netbeans and JavaFX

I am new to Netbeans and am only using it for the JavaFX integration (IntelliJ user) so I am not sure if I am dealing with my ignorance of Netbeans or some JavaFX idiosyncrasy.
However, when I try to organize my JavaFX code into package structure (rather than using a single default package) and go to run it I get NoClassDef exceptions on my main class. It looks like netbeans automatically packages up the files into a jar and runs it from a jar. I took a peek inside the generated jar and Netbeans is not maintaining the package structure inside the jar it is just putting all the classes at the root of the jar (hence the NoClassDefs).
How can I get Netbeans to maintain the package structure inside the jar?
Does JavaFX use the "package" keyword the same way as Java does?

Yep, after I was able to get my classes in a package structure (rather than default package) I discovered that.
I couldn't at first get my classes out of the default package. I am spoiled by IntelliJ which changes/adds package statements when you move classes. Netbeans did not automatically add the package statement when I moved from the default package to a package structure. Nor did it warn me that the classes were missing a package statement and/or the package statement didn't match its package location.

NetBeans and Heap Size

I'm trying to write a program using NetBeans and I keep getting OutOfMemoryErrors. I have 2GB of RAM and I've attempted to modify the netbeans.conf file to increase the heap size at startup. The changes I've made aren't being reflected in the memory manager tool (it still indicates a maximum size of ~50MB). The pertinent code from the config file is as follows:
netbeans_default_options="-J-Xms512m -J-Xmx1024m -J-XX:PermSize=128m -J-XX:MaxPermSize=512m -J-Xverify:none -J-Dapple.laf.useScreenMenuBar=true -J-XX:NewSize256m"
Assuming my memory usage won't exceed these limits, any suggestions as to how to make sure the changes are being implemented?

I would subscribe to the netbeans user mail list, and pose your question to that list. The Sun Netbeans gurus live there.
I would also use a seperate email account to subscribe to the list as it generates alot of messages daily. If thats not an option, definatly try to set up a rule that seperates messages from the list from your regular email.
The main netbeans top level mail list web page is here with all the instructions to subscribe and unsubscribe.
Good luck,

Re: (forte-users) Forte and CORBA question

Hi,
The discarding the Java variable that references a distributed Forte object
doesn't cause that the distributed object will be reclaimed. In Forte client
you can use ReleaseDistReference() of the current partition (task.part) to
free the remote object. For Java client, you can implement the following
solution:
- define a method ReleaseMyObject() in the SO you are using to get the proxy
to the dist. object. As parameter for it use something that can identify
your object (attribute).
- your SO has an array or hashtable with your distributed objects, every new
object is added to it.
- in the implementation of ReleaseMyObject() find the object to release in
the array and call ReleaseDistReference() for it,
- from the Java client, call the ReleaseMyObject() for the object that is
not more needed.

Hello Dave,
do you use a copy return or copy parameters in this method ?
If not, then maybe Forte is unable to garbage-collect this object because
it is forever
a proxy which only the server-partition may be able to drop it from memory
(object=NIL).
Try this and let us know what happens.

We're attempting to use a Java client to access a

We've had a Java client calling Forte service objects
and passing Forte objects back and forth as CORBA
structs with no problem. However, we have experienced
some problem obtaining and using remote references to
distributed objects from the Java client.
The problem is memory utilization. Each time I obtain
a reference to a new object, the memory utilization on
the Forte server jumps up quite a bit (around 100k per
object on an NT box). Eventually, if I fetch enough
objects, the server will crash due to lack of memory.
It seems that Forte never reclaims the memory, even
though I'm not using (and don't have a handle to) this
remote objects.
The objects are very small. In fact, I created a test
Forte SO with one method, getObject(); which returns a
distributed object with a single attribute. I then
have a Java client access the getObject() method
repeatedly - discarding the reference to the object
after each iteration. After a short while, the box
will come down.
Any thoughts?
Thanks in advance,

NetBeans and Morena/Twain

I am using NetBeans to develop a Windows graphics program. I am incorporatiing Morena/Twain code into it so that the program can scan images. I have included the Morena and ImageJ library JAR files in the program, and within the IDE, the program runs fine. But when I use the executableJAR file generated by NetBeans to run the program, the scanning capability doesn't work. I 've put the Morena/ImageJ library JAR files in the ClassPath I think by using Windows' System/Advanced commands. But I'm not sure that does it. What am I missing. Just putting these imaging files in the directory in which the NetBeans generated executable resides doesn't help either. I'd sincerely appreciate some help with this.

Hi All,
I'm obviously still not doing something correctly. I've added the Morena Jar files to the Manifest file and rebuilt the program. It seemed to work once. Then the same behavior appeared. The program initiates and everything but its scanning capability works fine. I"ve looked at the NetBean's generated Jar file. There is no reference to Morena/Twain in it. However, there is a folder called Morena Classes in the output directory of the generated program. I've also tried the other two methods described in the links you so kindly provided. Those don't resolve the problem either. I've tried putting the Morena files in the same folder as the generated Jar file. I've put the Morena class files in the build directory generated by NetBeans and rebuilt. And finally, I've tried incorporating the Morena Jars with the NetBeans program JAR into a new JAR file. Trying to run the last kicks a "Can't find a Main" message. The program still runs just fine within the NetBeans environment. Can you suggest a really good book that might cover this.

Please help.

Solution:
You have to Close the Project and reopen it. Than the DataProvider is available.

NetBeans and other software not available in the main solaris repository.

In the main(default) Solaris 11 Express repository we cannot find NetBeans and other software we could find in OpenSolaris in the extras repository,for example.Reading Solaris 11 Express release notes I find the main solaris repository and the support(for security and bug updates) repository,no other.Do we need to download directly in the NetBeans website,OpenOffice website etc.etc.,or are there any other repositories I did not see.

I just wrote an blog entry based on this question - http://blogs.sun.com/observatory/entry/left_behind. Bottom line, you can either download the software directly or add the opensolaris.org repository and get the IPS version.

Netbeans and issues

I'm working under netbeans, and I did an update recently to all the plug-ins that I have. Now because of that, I have those red squiggles everywhere even though there's no error associated with that line of code. Not only that, but it won't recognize any other methods or classes when I try to do the Auto comeplete. When I try to do the auto-complete, it comes back with the, "No suggestions" even though the class is in the same file. Any one run into this, and if so, is there a fix to this!?

YAY! I sloved my own problem! Heh. Ok, to solve this issue, all you have to do is:
1) Change your JDK to something else (doesn't matter unless you have methods that are depricated).
2) Clean and build.
3) Change back to your old JDK.
4) Clean and build again.
That solved it for me, and hopefully will solve it for others as well.
