JVM SUNONE GC problem
Our applciation uses struts, ojb and oracle; 100 users using the app all day; (in a client server fashion); but app is JSP.
We have major issue with garbage colelction. every day, once or twice FULL Colelction repeats itself for ever until we have to restart appserver.
our settings are 512MB for heap.
I have pasted few lines of one such instance. Can anyone help us with exp. and or suggestions to get us out of hole here.
THANKS SO MUCH>

1.Can you upload your GC log?
2.Strongly reccomend JProfiler, you'd better use remote profiling mode.
3.You must modify your program. Simply tuning will never fix such problem.

Too many kids in the sandbox: JDK1.1 (MS JVM) xerces/jaxp problem.
Hi all
I'm having a wee(?) problem using jaxp/xerces (DOM) on the microsoft
virtual machine.
I have a xml based chat server/client. The client is 1.1 compatible so that no plugin download is necessary. However, when the client tries to parse xml, it throws the exception below. I don't know why it tries to read the jaxp properties file from my local machine but it does.
I think the problem here is that the parser jar files are not included in the client jar file, but even when i do include them i get the same problem. (I'm aware of the security issues regarding reading local files, and I'm trying to avoid it, since i do not want to sign the client applet).
**When i run the same applet through the latest java runtime plugin, it works fine. this only happens on the MS JVM**
I'm aiming for a clean solution here. I don't want a big file download (parsers).
Is my best route to give up using the jaxp/xerces parsers, and just write my own mini-xml-parser code?
Thanks for any help
And may the duke be with you, always.
Harel

We are running weblogic 6.0, accessing it from cold fusion.
What we are seeing is, we can access the application server --
sometimes. Seems about 50% of the time we get succes, the other 50% we
are getting an exception "Exception: Cannot instantiate class:
weblogic.jndi.WLInitialContextFactory"
We have been trying to figure this out for days now, it appears that the
WLInitialContextFactory class is being unloaded and is failing on trying
to reload -- sometimes.
has anyone else out there seen problems like this and gotten a fix?
We made the jvm memory in cold fusion to 32MB's, 4MB's initial and it
doesnt seem to be running very low on memory.
We have changed from using jdk1.2.1, jdk1.2.2, jdk1.3 and they all seem
to perform the same. The percentage of failure seems to change slightly
but I am guessing that the gc in the different jvm's is working
differently.
Any help you can add will be MUCH appreciated!
-chrisThanks a lot!
I had the same problem and nearly go nuts with it. At Macromedia I only found
an article which described a 'limitation to ColdFusion classloader' (nice description
for a bug).

Switching from Microsoft JVM to sun JVM plugin. Problem w crystal reports
Hi,
I am currently in the process of switching off of the microsoft jvm to the sun plugin. I am using the reportviewerbean to view the reports. This works fine in the microsoft JVM, but I am getting a server not found error in the java JVM plugin. Here is the codes that is currently used:
bean = new ReportViewerBean();
if ( reportname.startsWith("/") )
java.net.URL url = this.getDocumentBase();
reportname = url.getProtocol() + "://" + url.getHost() + ":" + url.getPort() + reportname;
add((Component) bean);
((Component) bean).setBounds(0, 0, (int)this.getSize().width, (int)this.getSize().height);
bean.start();
bean.setBackground(Color.gray);
bean.setPromptOnRefresh(false);
bean.setHasGroupTree(false);
bean.setHasPrintButton(true);
//setZoomFactor(100);
bean.setZoomFactor(-2);
Log.debug("In report viewer: setting report parameters: "+reportparameters);
bean.setReportParameter(reportparameters);
* It's important to set the report name last. This tells the Crystal viewer to
* start the report. Otherwise you can get multiple URL requests for the same report.
Log.debug("In report viewer: setting reportname: "+reportname);
bean.setReportName(reportname);
Can anyone tell me what I am doing wrong or what I need to do differently for the SUN environment
ThanksHi
I have started playing with this again my full msg is:

I have noticed that the viewer is set to equal java and not java_plugin. I am wondering if this is the problem. does anyone know how to change the viewer= ?

have an indexing problem :
2 start points
1) myportal/portal/dt/ - main page robot can index it Oll Right
2) myportal/portal/dt/?provider=2DefTab&&2DefTabContaner.setSelected=Def98MainTableContainer&last=false&Def98TabContainer.setSelected=Def98STableContainer&tab=1&subdiv=01&node01=on&node5089=on&std_html=off&scroll_x=0&scroll_y=0 - dinamic page - robot can index only the first part of the page then
the interesting thing is however that teh first parts of the pages are identical and robot can index this part on main page and can not do it on the secons one
maybe some one faced this problem before? please helpDoes "_type" really have a leading underscore? That must be a PITA to work with. Sorry my bad it does not have an underscore.
the queries always states the type of the PARTY.
I am worried that this PARTY table is kind of abstract and we are putting two types of information into the same table.Does this effect my index design? -
Oracle Team?? EJBean Problem on Oracle JVM
Hi,
I am using Jdeveloper3.1 and Oracle8.1.6 for my application. I could deploy and run the EJB on Oracle JVM without any problems. But when I am trying to connect to the Database it is giving me the null value instead of 'Y' or 'N'. The same EJbean I used as the USEBEAN in JSP and it is giving me correct results. I tried to debug and I found it is not getting the connection.I am giving the example I tried.

Can you please tell me the problem. I have wasted 2 days on this.

nullYou're running this EJB in iAS, right?
You have to grant JAVAUSERPRIV to the user running your EJBs so that it is allowed to open a JDBC Thin socket out of the JVM to the backend database.

64-bit JNI C++ to JAVA invocation multiple threads classloader problem
Hi ALL,
I have a C++ app that invokes Java classes on 64-bit Solaris 10 with 64-bit JVM.
Here is the problem:
The native non-main (not the thread that initializes the JVM) threads would not be able to find any user-define class.
Here are the symptoms and observations:
1. JNIEnv::ExceptionDescribe() showed the following StackOverflowError:
Exception in thread "Thread-0" java.lang.StackOverflowError

at java.lang.ClassLoader.loadClass(ClassLoader.java:252)
at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320)2. The "main thread" that instantiates the JVM has no problem finding and loading any class or method
3. But the other threads (non-main threads) would not be able to find the user-defined classes unless the classes were already loaded by the main thread.
4. The non-main threads can find the "standard" java classes with no problem
5. The same app ran fine on 32-bit system.
6. Except for the JVM reference is global, each thread acquired JNIEnv by either GetEnv() or AttachCurrentThread().
Any idea why it is a problem with 64-bit?
I have the sample program to reproduce this issue in this thread: http://forums.sun.com/thread.jspa?messageID=10885363�. That was the original thread I raised but I have narrowed it down to a more concrete scenario. That's why I am creating this new thread. I hope this does not break any rule on this forum. If it does, I apologize.
I really appreciate it if anyone can provide any help/suggestion.

Connection Pooling problem in Weblogic Server 6.1
Hi
We are using weblogic server 6.1 sp3. The server creates three database connection
pools (details available in the attached config.xml).
The database has a regular downtime every day for a few hours. We are running
the server as a windows service. As per the "RefreshMinutes" property, the server
should be able to get new fresh connections once the database comes up. But in
our case it is not doing so. Once the database comes up after its regular downtime:
-- Sometimes the server does not respond as in we are not able to open the console
page.
-- Any client that tries connecting to the database thru the server gets blocked
and does not respond.
-- The log file(weblogic.log) does not get updated after some time.
Can someone suggest why the server is showing such a behaviour??
Could it be anything related to the DBMS setting or to the local machine's settings
? Following is the thread dump after the server stops responding:

Thanks for your useful suggestion.
BTW, I am attaching the config.xml for your
convenience.
Please go through and let us know if anything
to be tuned.
Regards.

Hi
We are using weblogic server 6.1 sp3. The server creates three databaseconnection
pools (details available in the attached config.xml).
The database has a regular downtime every day for a few hours. We arerunning
the server as a windows service. As per the "RefreshMinutes" property,the server
should be able to get new fresh connections once the database comesup. But in
our case it is not doing so. Once the database comes up after its regulardowntime:
-- Sometimes the server does not respond as in we are not able toopen the console
page.
-- Any client that tries connecting to the database thru the servergets blocked
and does not respond.
-- The log file(weblogic.log) does not get updated after some time.
Can someone suggest why the server is showing such a behaviour??
Could it be anything related to the DBMS setting or to the local machine'ssettings
? Following is the thread dump after the server stops responding:Hi. I do see a problem in the thread dump. The application code is calling
java.sql.DriverManager
calls, which are a serious problem in multithreaded applications like
weblogic, because
DriverManager calls are all class-synchronized! All JDBC drivers and
the SQLException constructor
call DriverManager calls all the time, so a single long-running call
to DriverManager.getConnection()
can stop all other JDBC in the whole JVM. One problem you can fix is
at:
at tavant.platform.jdbc.JDBCTransaction.getConnection(Unknown Source)
at tavant.platform.jdbc.JDBCTransaction.start(Unknown Source)
The getConnection() method should be altered to instantiate a Driver
object and
call Driver.connect() directly to make a pool connection, avoiding the
DriverManager
call:
Driver d = (Driver)Class.forName("weblogic.jdbc.pool.Driver").newInstance();
Connection c = d.connect("jdbc:weblogic:pool:" + myPoolName, null );
Let me know if you can make this application change and whether it fixes
the
problem or not.
I could also help if I could see the config.xml, but you seem to have
attached the
startup script.

Static member problem in multiple instance of web application
Problem
I am working on a product which is java based. I have a war file. I have to deploy this war file in JBoss. Further, I need to run multiple instance of this war file in same JBoss instance.
Issue
In that war file there is servlet Start.java. That servlet calls an other class from its init method. Here is code
public class Start extends HttpServlet
public void init(ServletConfig config) throws ServletException
super.init(config);
DB.loadProperties (�db.properties�);
} // init
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
} // doGet
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
} // doPost
} // Start
public final class DB implements Serializable
public static final String P_UID = "ApplicationUserID";
private static final String DEFAULT_UID = "System";
public static final String P_PWD = "ApplicationPassword";
private static final String DEFAULT_PWD ="System";
public static final String P_STORE_PWD = "StorePassword";
private static Properties s_prop = new Properties();
public static boolean loadProperties (String filename)
{ // looks for properties file
s_prop = new Properties();
FileInputStream fis = null;
try
fis = new FileInputStream(filename);
s_prop.load(fis);
fis.close();
catch (FileNotFoundException e)
log.warning(filename + " not found");
loadOK = false;
�}
As you can see if I deployed two instance of this war in JBoss and assume each instance point to its own properties file. The �Static� members are problem.
Restriction
I am not allowed change the code or logic of the product. I must be able to get some thing outside or apply a patch to solve this problem.
Please Help
Possible option that I have thought
1 Using multiple JVM - Not an option in this project
2 Using multiple JBoss � Not the requirement (need to run only on single Instance of JBoss)
3 Use own class loader for war/ear � don�t know how in JBoss need help.
I am using JBoss 3.2.3
Thanks,
KumaranStatic members belong to the class. So, you needto
think of multiple JVMs for your problem.Thanks for reply.
don�t know how in JBoss need helpJust guessing... clustered environment MAYBE
RichThanks Rich,
I don�t know how Cluster environment solve my problem. I need more information on your thought. Cloud you explain it.

hello
I have a problem related to the system date
(the date from JVM)
How can I change dynamically the date of a JVM?
my problem: I have to create a test case for
a trigger
I want to create an object, and I need to change
the date to see the result
I want to create a 'contract' object which
will expire at the end of this month. I want
to set the date to the next month and to see
the result (the contract should expire).
It's possible to do this by changing
the date of the system....but it's not at all automatically
Could somebody help me, please?
thanks
petrethe thread is a 'jdring' thread, a product that
is working like the old 'cron' daemon on unix
you can define the pattern to wake up the thread
('every day at 1:01 AM' for example)
when this thread is awaken then it executes a
JDBC request to see if there are contracts
where the expiration date has passed
if any...then it will set the status of those contracts
to 'expire'
the problem comes from the fact that the range of
expiration date is limited
(a contract can expire at the end of this
month | quarter | year )
so, I need to create a contract (stored in a database),
to change the date of the JVM somewhere after
the expiration date of the contract and then
to check the results.
the only solution I found is to change the system date
but it's not an automatically one
(stop the application, change the system date, restart application)
cheers and thanks
so I need to change (in my test program) the
date of the JVM so as to wake up the thread
Hi! What thread is this? Perhaps if you could explain
the situation in a greater detail, for the benefit of
slow folks like myself, we may be in a better shape to
offer suggestions.
Cheers! -

Cheers,
MikeHi ,
Try using -XnoOpt parameter. This option turns off adaptive optimization. While optimized code generally runs faster than code that hasn’t been optimized, occasionally, the time required to optimize code results in undesirable delays processing. -XnoOpt lets you avoid these delays by turning off optimization. This option is also helpful when you suspect that a JVM or application problem, such as a system crash or poor startup performance, might be related to optimization. You can turn optimization off and retry your application. If it then runs successfully, you can safely assume that the problem lies with code optimization
For more information check out the below link

Repaint problems with an applet under Netscape 4.75
Hello,
I'm currently working on an applet created with VisualAge for Java, running under the standard Netscape 4.75 JVM, with Windows NT4.
I am experiencing problems with AWT components which randomly disappear, especially Labels and sometimes Panels. When I drag a window over the missing label and then drag it back, the label appears.
I have tried a lot of combinations with the repaint(), paint(), paintAll() and paintComponents() methods, but it has not been efficient for the moment. Introducing lots of repaint() calls on the concerned labels is even worse.
Is there a known bug in the Netscape 4.75 JVM concerning this problem ? Do you have an idea of what can be done to solve this problem ? Changing the JVM is not an option that can be chosen. Netscape 4.75 has been defined as the only browser for the whole project.
Thanks for your help !
KevinWell, I finally solved this problem.
For your information, the JVM included in Netscape 4.75 running under NT4 does not like having AWT labels with either Background or Foreground not initialised. If any of these 2 properties is not defined, it could sometimes occur that the JVM can't display the label. -
Draggable window only works in MS JVM, and not Sun?
Hello all,
Our applet needs to support the MS JVM (and therefore Java 1.1). I have been looking to create a draggable Window to replace a Frame that we have since we want the frame to be 'undecorated' (no minimize button, etc). I found some code on this forum to create a draggable window which works fine. But, I would like to create my own title bar on the Window and only have that draggable. When I add the same listeners to the Label instead of the Window itself, the dragging no longer work so well in the Sun JVM, while it works fine in the MS JVM. The problem I am seeing is that if I don't drag slowly it skips, or doesnt drag. Note, I am only seeing this when adding the drag listeners to the Label in the Window, but this works fine when the listeners are on the Window itself. Also, this works fine in the MS JVM. Any ideas? For example, the code below is what has the issue in Sun JVM, but if I replace the 'title.' to 'this.' on the 2 listeners adds, I can drag the window fine in Sun JVM.
Thanks for you help,
Aaron
public class TestWindow extends Window {
Label title;
int width=300;
int height=300;
Point origin = new Point();
TestWindow() {
super(new Frame(""));
this.setBackground(Color.blue);
title = new Label("Draggable window");
title.setBackground(Color.gray);
//setLayout(new BorderLayout());
add(title, BorderLayout.NORTH);
title.addMouseMotionListener(new MouseMotionAdapter() {
public void mouseDragged(MouseEvent e) {
Point p = getLocation();
setLocation(p.x + e.getX() - origin.x,
p.y + e.getY() - origin.y);
title.addMouseListener(new MouseAdapter() {
public void mousePressed(MouseEvent e) {
origin.x = e.getX();
origin.y = e.getY();
this.setSize(width, height);
this.show();
}Sorry, I didn't read your post carefully the first time.... My suggestion would be to add listeners to both the label and the window, although that would make the whole window draggable. To nullify that effect, you'd have to put another component in the main part of your window (Like a JPanel if you could use Swing) and have it eat up any mouse dragged/clicked events that it receives.

IRT's MHP-RI HDD TS playback problem
Dear all,
I've got the license of the RI but now have no DVB-card at hand, so I am trying to get TS from HDD files. Below are my steps:
1. From the install instruction: "To configure the RI to play a TS from HDD, please configure it as first as having a Technotrend udget DVB board." So:
==> Frontends.cfg: comment [irtdvbtt] and uncomment [irtdvbbda]
==> System.cfg: set VIDEO.COMPOSITION_DLL = irtdvbbda
2.From the next step of the instruction:
==> Transponders.xml: add a new entry in the section "HDD TS Playback Transponders" and do not conflict with another transponder. So I set
<satellite frequency="1" orbposition="192" eastwest="E" polarisation="H" symbolrate="27500000" onid="1" tsid="437" nid="4"/>
==> LocalTransponders.cfg: I add a line
1="d:\TS\1.ts"
and I am sure the file exists in the correct path. Of course, the file has no problem itself.
==> Navigator.prop:
service1=IRT HDD Service
service1id=dvb://1.437.4
OK, the problem is why I cannot run the RI. When I execute it, the JVM has some problems:

If there's anyone who knows the solution or tells me the correct steps to setup the HDD TS playback, please email me or reply this post. I need the solution urgely. If anyone needs more information about my problem, please reply too.
my email : [email protected]
Thanks a lot!
Best regards to all.I have a problem too playing TS from Harddisk with the IRT RI..
I went through all steps and i am not quite sure if i configured it right and i am confused about the way my xlet tells the RI WHICH TS-file it wants to play..
Because i get a NoPlayerException when trying to play a TS-File, there must be something wrong with the parameters i use in my code or my configuration settings..
I got a ts-file with the following parameters:
Network-ID: 16
Transportstream-ID: 1080
Service-ID: 100
I set up the IRT RI as follows:
==> Transponders.xml:
satellite frequency="1" orbposition="192" eastwest="E" polarisation="H" symbolrate="27500000" onid="1" tsid="437" nid="4"/>
==> LocalTransponders.cfg:
1="d:\TS\MyStream.ts"
==> Navigator.prop:
service1=IRT HDD Service
service1id=dvb://1.437.4
==> Frontends.cfg: comment [irtdvbtt] and uncomment [irtdvbbda]
==> System.cfg: set VIDEO.COMPOSITION_DLL = irtdvbbda
Yet i have a few more questions concerning that topic:
1. Where exactly do i have to put my TS-File (has it to be in the same directory where my application is)?
2. the default settings of the irt ri seem to be:
==> Transponders.xml:
... onid="1" tsid="437" nid="4"/>
==> Navigator.prop:
service1=IRT HDD Service
service1id=dvb://1.437.4
but my TS-File has other SI-Information (NID:16 TS-ID:1080 SID: 100)..
Doesn't i have to change the default settings then to find my TS??
3. How do i actually create a player for my xlet then?
Is it something like:
targetVideo = new MediaLocator("dvb://16.1080.100");
or
targetVideo = new MediaLocator("dvb://1.437.4");
or maybe
targetVideo = new MediaLocator(" d:\TS\MyStream.ts");??????
As you can see, i am very confused of that feature and there is a big lack of know-how...
Could anybody help me please??
With best regards,
Alex. -
If you have a symmetric multiprocessing (SMP) server with multiple processors, is it useful for Java applications that are multithreaded? Can each Java thread run in a different processor?
Can the JVM itself run through multiple processors? If not, then I'm guessing SMP wouldn't be useful for application servers that only run in one JVM.
Any insights on this?
Thanks.Can the JVM itself run through multiple processors?
If not, then I'm guessing SMP wouldn't be useful for
application servers that only run in one JVM.A general problem with multiple threads executing simultaneously on an SMP machine, is that access to memory needs to be synchronized, which may result in performance bottlenecks.
Also, if the JVM you're using does not offer parallel GC, SMP won't help on the latency observed when GC has to stop all java threads ("Stop-Of-The-World" mechanism) to reclaim memory.
