NetBeans 6.1 and Java WebServer 7 problem under OpenSolaris

Hello, I have a big problem with NetBeans 6.1 (all upgrade installed) and Sun Java Webserver 7.0 (release 7.0U3 B06/16/2008 10:24); running under OpenSolaris snv_101a (2008.11 RC2).
The web server is installed into /opt/webserver7/ and run fine, but when I try to add it as a server under NetBeans 6.1 I receive the error about +/opt/webserver7/+ isn't a correct directory.
Any hint?
PS: the NetBeans plugin for the WebServer version is 1.6

Can you report it in NetBeans mailing lists [http://www.netbeans.org/community/lists/top.html|http://www.netbeans.org/community/lists/top.html] and [http://forums.netbeans.org/|http://forums.netbeans.org/] as well?

Problem with new-line-character and java.io.LineNumberReader under AIX

Hi folks,
I got the following problem: I wrote a little parser that reads in a plain-text, tabulator-separated, line-formatted logfile (and later on safes the data to a 2-dimensional Vector). This logfile was originally generated by an AIX ksh script, however, I copied it on my Windows machine to work with it (for I'm using a Java editor that runs under Win Systems).
For any reason, Windows, and what is worse Java too, seems not to recognize correctly the new-line character (in the API it is written that this should be a newline '\n' or a carriage-return '\r' or one followed by the other) that marks the end of a line in the logfile.
Also, when I'm opening the logfile with the "Notepad"-editor, this special character does not seem to be recognized, every line is inserted right after the other.
On the other side, when I open the logfile with the built-in editor in the CMD-Shell ("Dos-shell"), the newline chars seem to be recognized correctly.
But when start my parser on the AIX-machine the newline does not seem to be recognized correctly again.
I tried to read in the logfile with MS-Excel and safe it as a plain-text, tabulator-separated, line-formatted logfile again, with such files my parser works fine both on the AIX as it does on Windows.
Any ideas? Anybody got over the same problem already?

Under windows, text files' lines are usually delimited by \r\n,
under Unix/Linux/AIX etc. \n
and under Mac \r.
I recommend to use the following editors, which are capable to handle files with Unix and Windows-styled line-delimiters or convert between these types:
Programmer's File Editor (PFE; available on Windows)
The Nirvana Editor (http://www.nedit.org/; available on Unix, MAcOS, Windows)
(BTW good old vim can handle that too. Transferring text files to windows in order to edit them, even using Excel for this purpose means your being a UNIX newbie, (I mean no offense by writing this) so vim is probably beyond your reach for the moment.)
Java normally assumes the platform's line delimiters where it is running, so if you transferred the file from Unix to Windows might be distrurbing.

Cache and/or Connection problems under load

I have a Kodo web app that's been running just fine in
production for many months now. However, recently the web
traffic has shot up by a huge amount, literally overnight.
But unfortunately, it's caused the app to fail very ungracefully
under the strain.
It's been a crazy few days, and I haven't been able to do
very much analysis because of higher priorities. But from
what I have been able to gleen, it now looks like Kodo is
the most likely culprit. From what I've read in other messages
here, it appears others may have been experiencing similar
problems.
My environment: Redhat Linux 8, Postgres 7.3.4 with the
included JDBC3 driver, Apache 1.3.x, Tomcat 4.1.x and the
webapp connector. Similar behavior was seen with Apache 2.x,
Tomcat 4.1.x and the JK2 connector (that was on the new machine
I setup to handle the new traffic, which, of course, died the
night before).
As I mentioned, this app has been running reliably for
months with no problems. But when placed under heavy load,
it appears to get into some sort of pathological state where
it slows down dramatically (asymptotically?) to the point where
it's effectively locked up. In one case, where the app was
left running for several hours in this state, requests were
taking 90 minutes to complete (normal is 1-5 seconds).
From what I can deduce, there seem to be four things
going on, three of which have been mentioned in recent threads
here:
1) Excessive memory consumption. When the app is
operating normally, I see fairly flat memory usage for
the JVM process. Under load, the JVM steadily expands
until it hits its heap limit. I've gotten OutOfMemory
exceptions with a heap size of 350MB, which should be plenty.
2) Level 2 cache locking issues. I've seen dozens of
threads waiting on a lock in the DataCache code. Not sure
if there's a deadlock happening here or just that the
threads are waiting on a lock that's being held for a long time.
3) Database Connection leaks or contention. I see threads
spinning in the DataSource code trying to get a connection.
I also see dozens of connections from the Postgres side which
seem to be sitting idle, but in the middle of a transaction.
When things get bad, I also see exceptions being thrown because
of timeouts waiting for a connection to become available. It's
a web app, PMs should not be tied up for more than a few seconds.
4) CPU usage pegged or nearly so for the JVM. I suspect
this is related to #3. Something very bad is going on here.
If I stop all inbound requests to the JVM when it's in this
bad state, it will continue to burn CPU at 90%+ for a very
long time. I think it will eventually finish what it's doing,
but I haven't had the luxury of waiting for it. It's definitely
not a linear slowdown proportional to the load.
Attached are my kodo.properties file and some thread stack
traces along with some comments. Any advice would be greatly
appreciated. This is not a complicated app nor am I doing
anything unusual. It doesn't seem logical that Kodo could
breakdown so dramatically under load, so I'm hoping it's some
sort of interaction thing that I can work around.
Thanks.

Please read prior posts regarding level 2 cache. It is unusable under stress
as far I am concerned. Basically entire cache gets locked on any database
read. Makes it very unscalable
Are you using 2.5.3? It will request a connection from a pool every time it
resolves reference to a PC even if it is cached in PM and therefore Kodo
does not need to read any. As result if you iterate over 100 objects in your
query and for each object resolve reference to another object (always the
same) kodo will request 100 database connections from the pool (and note
they issue rollback on every time they return a connection to the pool so
getting connection might be fairly expensive)
In conjunction with level 2 cache contention this causes application to go
into a stupor.
Try to go back to 2.5.2 (or may be 2.5.4 they promised in the near future
with a workaround) or use "persistent-manager" connection retention if you
discard PM after each HTTP invocation - it will take care of connection
pooling issue. As far as L2 cache I was unable to find any work around so
far - see if you might be better of without cache. You might if your object
graph is not very complex

With cahce enabled, 2.5.3
Here the app had recently slowed down and then effectively locked up.
There where many outstanding web requests that were not receiving output.
At this point most threads seemed to be waiting at the same location.
There were a large number of active database connections and most of
them had open transactions (according to pg_stat_activity). The app
was not responding to any web requests.
It would seem that db transactions had been started, then the thread
got stuck for a long time on a synchronization lock in the cache lookup.
Below are two randomly chosen thread stack dumps.

while running slow, 2.5.3
At this point, the app had been running several hours normally, then
apparently slowed down and locked up while I was away. When looking
at the app threads and database activity, everything appeared idle.
No transactions seemed to be open in the db. But the app was not
behaving normally. Web requests that did not make use of JDO worked
fine (but slow). But requests that hit the db either blocked or were
very slow to respond.
Looking back at the log, there had been a large number of requests
that threw exceptions because they could not get a connection within
five seconds.
Most threads were idle, waiting on read, but some were in the state
shown by the following two stack dumps. Unlike the cache threads above,
they did not seem to be waiting for a lock to be granted, they seemed
to be spinning in the connection management code. Apparently trying
to get a connection. I suspended and resumed the same thread repeatedly
and it always seemd to be doing the same thing. Single stepping was
very difficult because the debugger was slow to respond, apparently
because of other threads also busy spinning.
Postgres indicated that there where lots of connections open and
that they were all idle, so there should not have been a shortage
of connections in the pool. There are two mysteries here: 1) why
can't this thread get a connection? and 2) Why is it busy spinning?

With cache disabled 2.4.3
This run was an accident. I inadvertently ran the app with the older
2.4.3 version of Kodo, with the cache disabled. This one got into trouble
almost immediately. It also seemed to lockup with lots of opentransactions
in the db. It's also interesting that these two threads also seem to be
hanging around the same method as in 2.5.3.

Java install problem under redhat 9

I download rpm and install it under redhat 9. I can compile program (the class file is generated) but can not run it.
I checked the path and see /usr/java/j2sdk1.4.2_04. WHen I check the version, it tell me version "1.3.1". It soulds like I have 2 different version of java installed. How can I solve this problem?
Thanks

Probably not a mix up. Try to update your path wirh the path to the bin directory of the java version you want to use. Something like :
export PATH=/usr/java/j2sdk1.4.2_04/bin:$PATH

Oracle Workflow Manager, Agent Listener, and Java Mailer problem

Hi,
I am not sure this topic to this forum, since this might be installation issue.
But I am hitting a big wall.
I had Windows 2000 SP4.
I have already installed Oracle Database 10gR1, Oracle Developer 10gR2, and Oracle Workflow 2.6.3 Standalone previously.
Including :
- Oracle Workflow Server 2.6.3
- Oracle Workflow Builder 2.6.3.5
- Apache HTTP Server 9.0.4
- Workflow Middle Tier
Anything seems to right, including the Notification Mailer and the Business Event.
And I had also made backup of them surely.
Now,
I'd like to change into Oracle Database 10gR2 because :
1. Some errors I found when I tried to call a Report from Oracle Form.
Unable to connect to Report Server ...
I thought Oracle Database 10gR1 is not suitable for Oracle Developer 10gR2.
2. And in the OWF 2.6.3 Workflow Home Page, there was no Logout button (which I found in OWF 2.6.4)
I removed my previous installation including Oracle Workflow.
After strugglineg in the installation of Oracle Database 10gR2, now I am facing another problem with Oracle Workflow.
I succesfully installed Oracle Workflow 2.6.4 Server and Oracle Workflow Manager (standalone version),
and the Oracle Workflow Middle Tier.
After I launch Oracle Workflow Configuration Assisstant, everthing seems to be normal.
I succed to open the Oracle Workflow Home Page (and found the Logout button there)
Next, I tried to navigate to the Oracle Workflow Manager.
1. I start the OC4J_Workflow_Management_Container --> initialized
2. OC4J_Workflow_Component_Container
The following error line appeared in the OC4J command prompt
06/05/26 10:31:40 LOG_ID_UNKNOWN : oracle.apps.fnd.cp.gsc.Logger.Logger(String,
int) : Logging to System.out until necessary parameters are retrieved for Logger
to be properly started.
06/05/26 10:31:40 LOG_ID_UNKNOWN : oracle.apps.fnd.cp.gsc.SvcComponentContainer.

06/05/26 10:31:40 LOG_ID_UNKNOWN : oracle.apps.fnd.cp.gsc.SvcComponentContainer.
getNewWorkflowContext() : BEGIN
06/05/26 10:31:45 LOG_ID_UNKNOWN : oracle.apps.fnd.cp.gsc.SvcComponentContainer.
loadGlobalParameters() : BEGIN
06/05/26 10:31:48 oracle.apps.fnd.wf.common.ContextFactoryException: Unable to g
et connection from data source because the following Exception occurred -> java.
sql.SQLException: ORA-28000: the account is locked
06/05/26 10:33:57 Oracle Application Server Containers for J2EE 10g (9.0.4.1.0)
initialized
3. finally it initialized
Next I tried to go to Oracle Workflow Manager from related link of Enterprise Manager
It is said that the OWF_MGR is locked
(I surprised since I had UNLOCKED the OWF_MGR after the installation and succeed to login at the Workflow Home Page)
And the following error line appeared in the commaned prompt after that
06/05/26 10:35:03 OrionCMTConnection not closed, check your code!
06/05/26 10:35:03 Logical connection not closed, check your code!
06/05/26 10:35:03 (Use -Djdbc.connection.debug=true to find out where the leaked
connection was created)
4. I re-UNLOCK the OWF_MGR and login to Oracle Workflow Manager
I noticed that the Agent Listener and Notification Service is Unavailable
(In OWF 2.6.3, The Agent Listener was started and Notification Service was waiting to be configured)
I tried to start one of the Agent Listener, but the following error appeared
ERROR: The Service Component Container is not running
Well, I had the same problem when installing the OWF 2.6.3
I tried to uninstall (remove) and re-install it like I had done before in OWF 2.6.3
(based on someone's post in Oracle's forum)
But this time, the re-installation won't fix this problem. (It was succeed in the OWF 2.6.3)
Everytime I start the OC4J, using wfmgrstart.bat and wfsvcstart.bat
the OWF_MGR is re-LOCKED(TIME) automatically.
And the servlet (WFALSNRSVC and WFMLRSVC) are not running.
I am worry, since I cannot use the Notification Mailer if this problem had not fixed yet.
(In OWF 2.6.3, the mailer was not available until those servlet is Started)
Sorry for the long post.
Any help would be grateful.
Many thanks,
Buntoro

Hi,
Finally, I have found the solution.
Step :
1. Start all of the Oracle Service, except for the OC4J
If you have already started OC4J, then stop them
Unlocked the <wf_manager_user>
2. Search in your Oracle Home : data-sources.xml
There should be two files,
one is in the ...\OC4J_Workflow_Component_Container\application-deployments\WFALSNRSVCApp
the other is in ...\OC4J_Workflow_Component_Container\application-deployments\WFMLRSVCApp
3. Make sure, you create back up of them.
4. Replace the following line
password="->pwForOwfMgr"
with
password="<your_wf_manager_password>",
should be look like this
password="a"
5. Now start the OC4J using wfmgrstart.bat and wfsvcstart.bat
6. Next, login to the Oracle Workflow Manager
This worked for me.
Hope this will help someone who has the same problem.

SQL Developer and Java GUI problems

I am having a problem with all the java apps i use, including Oracle SQL Developer. When i load up SQL developer, the top of the "Connections" text is chopped off as well as all the table names in the list when I make a connection. Also the java buttons are rather large. Almost as if they have a carriage return in the text of the button.
Its seems the gui configuration for java has been corrupted, but i cannot find where to modify those settings. I cant find anything on the internet on this. I have checked my video card settings and modified them to see if that is the issue, but it doesnt fix the problem.
Since other java apps do the same thing, I know its a java issue, but Ive uninstalled all the JRE's and JDKs i have and reinstalled them, and I still have the problem.
Im on an Windows XP box and running the JDK and JRE 1.5.0_09 versions. Any help would be appreciated. its very annoying to not be able to read some of the text in the java apps including sql developer due to the tops being cut off.
I have an ATI RADEON 7000 on an DELL optiplex gx620.
any help would be appreciated

The first thing to try, if you haven't already, is to update your video driver.

Windows xp and java.exe problem

Hello all..
I tried to execute have a batch file consisting a jar file and classes in windows xp platform. I used j2sdk1.4.0_03. All my classes are stored in : C:\MyDocument\Softwares\classes directory
and the jar files are in: C:\MyDocument\Softwares.
I wrote the following commands in the batch file:
java -classpath C:\MyDocument\Softwares\classes;
C:\MyDocument\Softwares\jexcelapi.jar mainClass
When I lauched that batch file, a message came out:
java.exe has encountered a problem and needs to close. We are sorry for the inconvenience.
Could you tell me where the problem is and why? Do I need windows xp patch to eliminate the problem? And where can I find that patch?
Thanx for any suggestions...
Richard

Thanks for your comments. I have tried to reinstall the J2SDK, but then another error message appeared:
Error occured during the initialization of VM
java/lang/NoClassDefFoundError:java/lang/Object
I've checked my Path and it's set as following:
C:\j2sdk1.4.0_03\bin;
and my classpath setting:
C:\MyDocument\Softwares;C:\MyDocument\Softwares\classes;C:\j2sdk1.4.0_03\lib;
When I tried to execute the java command in any directory (inclusively in C:\MyDocument\Softwares) I always got that message. The only directory where I was able to run the command is in C:\j2sdk1.4.0_03\bin;
Before I did the reinstallation, I never had such a problem.
Have any hits? Thanks in advance..

About Netbeans 6.5 and Java EE 5 SDK

Hi, I have already installed JDK 6u11 (with JRE) and Netbeans 6.5, do I still need to install J2EE SDK if I want to develop J2EE programs?
Thanks!

That message is true if you did not install the bundled tomcat server that comes included with NB6. Otherwise you will have to start tomat up separately with the tomcat6.exe and add a NEW tomcat server to NB.

ISO and DVD drive problems under Mavericks

Since I upgraded my Macbook Pro (15-inch, Early 2011) from Lion to Mavericks I have had problems with ISOs and my DVD drive.
If I download this ISO image for Ubuntu 12.04:
http://mirror.ox.ac.uk/sites/releases.ubuntu.com/releases//precise/ubuntu-12.04. 4-desktop-i386.iso
The md5 checksum of the ISO and it is correct: 14ad92270218a8925d802b3d3b6e140f according to the list at:
https://help.ubuntu.com/community/UbuntuHashes#A12.04_LTS
If I try to mount it, Mavericks reports that there are no mountable file systems.
If I write this to a DVD using Disc Utility and then try to mount the physical disc, Mavericks reports that the disc is unreadable and offers to eject it.
If I run Virtualbox and attach the image to the virtual CD drive device, it boots and installs fine.
Does anyone have any idea what is going on here with Mavericks?
What is Mavericks doing differently?

ok this just got ultra wierd. i tried running the comp with just one optical drive and my monitor stopped detecting a signal.so i plugged the second drive back in and it started working again. i tried this several times. then i tried running the comp with no optical drives and it worked fine. so it works with 2 or none lol. what a crazy system. i beginning to think this system is hopeless. i have replaced the mobo, and the PSU just to get the graphics card working properly. but now my dvd drive is acting up. grrr.

COMMUNICATION BETWEEN JAVASCRIPT AND JAVA APPLET: US$20 AWARD FOR SOLUTION!

COMMUNICATION BETWEEN JAVASCRIPT AND JAVA APPLET PROBLEM (Easy Filter Java Applet) -
US$20 TO ANYONE WHO CAN RESOLVE THE PROBLEM
To forum visitors:
I am prepared to pay a standard shareware fee of US$20 to a user who can resolve this technical problem.
If your advice resolves the problem, I'll forward the payment to your postal address (include your
address with your reply, and also your email address)
I am attempting to enable a HTML button (using Javascript's onClick command) to directly input a number into one of the parameter text boxes in the Easy Filter Java applet (ie, enter a new color value number in the text field of the standard Colors Multiplicator Filter interface).
The applet is Freeware and can be downloaded at: http://www.javazoom.net/applets/easyfilter10/EasyFilter10.html
(It is a very effective bitmap display and editing utility)
To achieve this, I am trying to access the part of the applet that defines and sets the textbox. The text box is defined in the .class file by accessing the parameter details in the genericfilter.txt file (accompanies the .class files). I need to access 'private String appletInitialize()' and then one of the 'textFieldParameters' which sets the textbox.
I understand the basic syntax for referencing the applet:
document.appletname.setString("An example"). However, accessing the text fields in this applet is more complex!!
Please can you recommend the correct Javascript syntax to achieve communication with the applet.
Thank you for your kind assistance.

Problem with Netbeans 7.1 and ME SDK 3.0.5 plugin

Hi!
I have problem plugin ME SDK 3.0.5 to Netbeans 7.1. When I try to install plugin into Netbeans I get this kind informations:
Warning - could not install some modules: Profiler (Java ME Projects Support) - The module named org.netbeans.modules.profiler/1 was needed and not found. Java ME SDK CPU Profiler Snapshot Viewer - The module named org.netbeans.modules.profiler/1 was needed and not found. 5 further modules could not be installed due to the above problems.
Does anyone know what is wrong?
I am truly grateful for the answer!

Hi Anvi,
I think you posted in the right place as the J2ME SDK Team read this forum (though they sometimes don't respond promptly as we would have liked). I also got the same issue as you, but check out the responses by the J2ME SDK Team to: https://blogs.oracle.com/javamesdk/entry/update_java_me_sdk_through
It seems there are issues with Netbeans 7.1, and they are fixing things for the next release for Netbeans 7.1.1 so I am sure they are aware of problems that we are encountering. Its fine for Netbeans 6.9/7 if you cannot wait though.

Netbeans and Java compilation

Hi all,
I got a number of files done by Netbeans but when I use those file for compilation in normal Java (it means not compiling in netbeans but in Java), i got some problem with the code automatically generated by netbeans.
can anyone help me a solution for the chance of compiling my files (all of them still .java) in normal Java (javac ...) because if not, i will have to do again all the code for UIs :(
thanks all

thanks for reply.
when i try to compile in normal command prompt, the part relating to "position" of each component in the frame generated by Netbeans appear to be errors, e.g. "package org.jdesktop.layout does not exist" which means to me that this would be a only-in-netbeans library.
is there any way for me to link to a specific classpath to get this compilable ?
and, by the way, i have one more question raised from Netbeans.
I try to read a .txt (text ) file in Netbeans by placing that file into the "src" folder but netbeans said "FileNotFoundException" and when i try to read the properties of text file, it states "unrecognized file". any idea how to get Netbeans recognise this file???
