JConsole 6 PID connection problems
I have written a small program that I would like to manage using JMX. Using JDK 5 everything works fine. But since I migrated to JDK 6 the JMX part does not work anymore. Here is the code of the MBean that I would like to manage:
Interface
public interface HelloMBean {
public String test() throws java.rmi.RemoteException;
Class
public class Hello implements HelloMBean {
public String test() { return "Hello"; } throws java.rmi.RemoteException;
public Hello() {
try { ManagementFactory.getPlatformMBeanServer().registerMBean(this, new ObjectName(getClass().getPackage().getName().concat(":type=").concat(getClass().getSimpleName()))); }
catch (Exception E) { LOG.throwing(getClass().getName(), "<init>", E); }
}When using JConsole from JDK 6 and try to connect using the PID method, JConsole tries to connect to the (correct) PID forever.
I scanned through the forum and other sources in the Internet but all the proposed trouble-shoots did not help. I checked the TMP directory and inside is a directory named "hsperfdata_bwuest01". Inside this directory one file per JVM is, named for the PID of the JVM process (e.g. 2772, which I try to connect to in JConsole). The access rights to this directory are (oh, sorry, I am using Windows XP on NTFS):
d:\document and settings\bwuest01\local settings\temp\hsperfdata_bwuest01 bwuest01:F
d:\document and settings\bwuest01\local settings\temp\hsperfdata_bwuest01 everyone:RHope that someone can help me with this issue, because I do not want to migrate back to JDK 5.
Hi,
Sorry for taking some days to come back but I am no more a "hardcore" developer, but rather hope to find some time to code once a month.
I have cleared my PC from all Java versions except JDK 6.0 with the following version information:
java version "1.6.0_01"
Java(TM) SE Runtime Environment (build 1.6.0_01-b06)
Java HotSpot(TM) Client VM (build 1.6.0_01-b06, mixed mode, sharing)
Here is the log that is printed by the server application with logging of JMX enabled:

And here is the log of JConsole with the option you proposed:
This is all that JConsole prints while having debug active => it is nothing! That is the reason why I am so puzzled about this problem. If I would get some kind of an exception, even it is one of those "nothing-saying NPE", I would have an indication that there is a problem somewhere. But looking at the current logs (well, JConsole did not print one) I cannot identify any problem, except that things are not working. However, as I already mentioned, I could manage to make it work with coding the "stay in main-method forever" in a different way.
Best regards,

Connectivity problem with MS BizTalk Server 2010
Hi colleagues,
I have a connectivity problem between MS BizTalk Server 2010 and SAP.
There are two virtual machines (VMs on VMWare), the first one is SAP ERP6 Ehp6 (IDES), and second one is MS BizTalk Server 2010 (BT). On BT side I have deployed a package which sends ORDERS05 document to SAP and has to receive a reverse call. The bottom line is that SAP can receive a call from BT but cannot send a reverse call. Gateway monotor shows the connection:
In the trace file I can't see anything suspicious:

Prxy Trace = 0Hi Deepak,
Thanks for the answer, but this is not the case I'm afraid. I've received an error message for BizTalk instance:
"Microsoft.ServiceModel.Channels.Common.XmlReaderParsingException: The segment name is not valid for the IDOCTYP, Release, or CIMTYP. Segment name: E2EDP01006GRP IDOCTYP: ORDERS05 Release: 620 CIMTYP: . Ensure that your message xml validates against the operation schema.
Don't really understood what does it want from me... -
Timeouts and connection problems after 5.1(2) upgrade
AIM/chat and some other programs are having timeout/connection problems after upgrade to 5.1(2). I am using S241 also. The connection problems stopped when the IPS was set to bypass. Rebuilt IPS and left sigs at default settings and problem is still happening. I am not seeing any of the IPs that are having the problem in the Event Viewer or on the Events in the IDM.
Any known issues with the 5.1(2) that would cause this type of problem?I don't know specifically, but I did notice that 5.1(3) was released today.

Hi, i am having trouble with my mac mail account, i cannot send or receive any emails because of the server connection problems. Message says it could not be connected to SMTP server. Thanks in advance for your help.
Hello Sue,
I have an iPad 3, iPad Mini and iPhone 5S and they are all sluggish on capitalisation using shift keys. I hope that Apple will solve the problem because it is driving me crazy.
I find using a Microsoft Surface and Windows 8 phone, which I also have, work as well as all the ios devices before the ios 7 upgrade.
It has something to do with the length of time that you need to hold the shift key down. The shift key needs to be held longer than the letter key for the capitalisation to work. For some reason, this is a major change in the way we have learnt to touch type on computers. I am having to relearn how to type!

Unending connectivity problems -- and Desktop Help...
I'm wasting so much time on connectivity problems that it's positively wearying. Prior to the installation of BT Infinity here in April, I had a low quality broadband service because of the length of the line from the exchange: if I could get a download speed of 1.2Mbps and an upload of a quarter of that, I was doing well.
BT advised that thanks to fibre optic, my Internet should run much faster. So we had Infinity installed. I'm registered with Speedtest.net so am able to see my performance record.
The average download speed is now aroun d 6Mbps and the average upload, more than that at 7Mbps. How an upload speed can consistently be faster than a download escapes me.
But I'm not familiar with the ways of Internet connectivity and try as a I might, can't get my head around it.
This desktop computer runs Vista OS. Vista was **bleep** when it came out and is renowned for its botched handling of Internet connections. So I'm not blaming BT for the literally unending connectivity problems that are occurring now, with line drops, speeds slowing to a crawl, and no guarantee that any connection will last. But it would be good to actually use BT software to help fathom out what's going wrong here, and today's typical morning which looks like this:
1) Boot up computer. Automatic connection to hub via Netgear USB wireless adapter. Hub is on ground floor of this 3-storey property but signal strength from hub is excellent, as confirmed by inSSIDer monitoring, currently showing 54 with no other networks anywhere near that figure.
2) Perhaps 5 minutes after connection established, it's then lost. 'Local Only' is displayed. This is, apparently, a known Vista problem. But Microsoft has issued a fix for it. I know this, because it took 100 hours of ploughin g the Net to find out that MS had finally admitted to one more Vista screw-up. I've used the Microsoft router "fix it" before and it didn't work ("failed to process") so uninstalled it and have DL'd it again now and run it. This time it says it has fixed everything.
3) Computer is re-booted to make the fix effective. Computer connects to Internet. Speedtest.net check yet again confirms that upload speed is faster than download speed.
4) Connection dies. So much for Microsoft Fix It.
5) Windows diagnostics reports that it can re-set the IP profile (or something.) I click yes. The re-set goes through. Connectivity is restored. 10 minutes later, connectivity is lost. Just a red X in the tray. No connection of any kind, not even that daft 'Local Connection' only alert.
6) Reboot. Yet again. BT Desktop Help was installed here and ran OK when we were using our Netgear DSG34 router. But since the change to the BT Hub, the BT program has never run at all. So-oo. . . It has been uninstalled. And then re-DL'd and re-installed. And though the installation has been completed, clicking on 'launch' has failed to launch anything. But anyway. An hour ago, in one of the brief periods today when the Internet connection was holding up, I Revo-ed out the earlier install, DL'd BT desktop Help and re-installed it. . . and I'm still at the same stage as always, with a Firefox browser page that's open and completely blank and has been for the past 30 minutes. The URL is:
file:///C:/Program%20Files/BT%20Broadband%20Desktop%20Help/btbb/Start.html
Repeated page re-loading gets nowhere. Malwarebytes PRO is turned OFF to prevent any possibility of blocking and the antivirus is termporaily SUSPENDED. This PC runs on Windows standard firewall but even turning that OFF doesn't get the page to load. Copying the address into Internet Explorer in case there's a Firefox problem merely results in Firefox being opened and the same blank page running there.
7) After all that. . . Connection lost yet again and this time, Windows cannot connect at all. It reports that the "wireless network security key is not correct". I happen to know that it is, because this is maybe the 20th time it has reported this in the past 10 days and every time I have to key in the "correct" key all over again. . . at which point Windows still says it isn't correct and cannot repair.
Turning off the computer completely, unplugging from the wall, holding in the power switch for a full minute to clear the circuits, traipsing up and dowen three flights of stairs to turn off the hub, then wait, then turn the power back onm again. . . Ah, wot fun times I'm having here with my particular versioin of Infinity (as in, an infinity of connectivcity problems.)
Summary: I seem to be being simultaneously hit with one issue after another.
I'm bewildered as to why ever since Infinity was installed here, my upload speed is generally faster than my download speed. I'm not happy with endless Internet connection failures though am thinking that Vista is playing a large part here with its "wrong security key" and unending 'Local Only / Limited Connection' failures. I do miss my Netgear router and the ability to access a fantastic help menu and re-boot directly from the desktop without having to keep going up and down three flights of sdtairs to do so (I haven't been able to find out how toe access the BT Hub remotely.)
Above all though: I'm really tired of repeatedly trying to run freshly downloaded and installed BT Desktop Help software but getting no further than a blank page because the program has stalled.
If anyone has any advice / suggestions, other than to buy a carrier pigeon, that'd be much appreciated.
Thanks.Thanks again to John and gg30340. Here's an update:
1) BT Desktop Help removed completely from this computer. The uninstaller itself mopped up everything, which surprised me. But anyway.
2) Bt Home Hub manager set up and working. Had to input serial number and create new password. All of this sounds fairly easy and would be if one had the device near the desk. But the idiots who built this property shoved the BT master socket inside the garage next to the door. Our two home computers are on the third floor. To ensure the wireless signal strength is OK, the Hub and Infinity module/device/whatever it's called are on a high shelf. It's a major job to even reach the darn things, never mind read the labels seeing as how the BT Infinity engineer was good enough to tidy up the cabling and make a very tight connection to the wall socket.
3) I had hoped to be able to back up the Hub's settings, seeing as the software provides for Advanced Settings / System / Backup. But not on mine (Hub 3.0). All that System allows is choosing which internet clock to define the accurate time. Everything else in System is just a pattern of short lines as if trying to indicate that there's some text there but it's invisible.This is now my second encounter with BT software which, for whatever reason, isn't functioning as it should on this PC.
4) Hub reset to factory fresh, according to BT guide.
5) Reset appears to have achieved nothing apart from requiring the password to be popped in again. After reset, it wasn't even possible to connect to the hub manager. Internet connectivity was eventually established for all of 30 seconds and then, gone.
6) Computer was shut down and then booted anew. Internet connectivity is still. . . dreadful. One minute everything's fine and then, literally,. the next minute a webpage won't load. Even opening the Hub Manager has taken three attempts, i.e., disconnecting from the Internet, re-connecting, failing, and trying twice more until success. Yet all the time these failures are occurring, the tray icon is showing a steady, unwavering green icon for Local and Internet access -- despite the fact, there manifestly isn't any.
7) Speedtest. net tests are actually showing upload and download 'trajectories' going slower and slower and finally halting at some point on the arc, then after a period of up to 30 seconds, suddenly becoming animated again. Speed test results with broadband speed checker UK and Think Broadband's checker are so at variance with one another, and with Speedtest, net, that it seems all three are using different technologies in pursuit of the same thing. Either way, upload speeds continue to be much, much faster than download speeds, a state of affairs I certainly have never encountered before.
8) Speedtest net tests taken in the past 10 minutes, with one test following on from its predecessor, begin at 8.24 down/8.88 up, followed by 5.24 down / 6.40 up, followed by a mind-numbingly lonnnnng 0.62 down / 8.70 up -- in other words, a continuous yo-yoin g of Internet connectivity to the pooint that it actually might as well not even be here (I've had to make five attempts just to get on to this forum. . .)
9) BT Speedtest will necessitate disconnection of everything downstairs and all boxes being lugged up here. This is actually going to require uncoililng tied-off cabling and hanging off a stepladder to do so -- though I surely can't be the only person in Britain who doesn't have a nice, handy BT master socket in their study or lounge. That said though: until we switched to Infinity, we *never* experienced these kinds of horrendous connectivity problems and never had need to unplug the Netgear router downstairs and bring it upstairs to connect directly to tjhe desktop PC so BT's own test could be run.
I'll just have to get to work dismantling stuff tomorrow. However, I have to say that after a factory re-set which has changed nothing at all, I'm beginning to think there's a problem with the BT line itself (hence why I'm happy to follow the advice here, though less than happy at the prospect of the messing about involved.)
Thanks, you two, for your patient help, and also for clarifying the situation re the three signal paths being shown on inSSIDer. At least I know that's usual now! And now, hopefully, when I press 'Post', I won't be faced with an endlessly spinning Firefox circle culminating in what may well be, or seem to be, the 57,938th time today of seeing "Page Not Found". . . -
PHP and MySQL Connection problem
I am trying to make a PHP MySQL on a remote server connection in Dreamwesaver CS3.
When I enter the information (host, user, password, etc.) and hit TEST, I get the following error message.
"Access Denied. The file may not exist, or there could be a permission problem. Make sure you have proper authorization on the server and the server is properly configured."
I know the user, password, etc. work, as I can access the MySQL database with other software.
I checked with my host and they say there are no permission problems on their end.
I have checked the settings on the Test Server page in Site Setup and everything looks correct and works there.
I have not seen this particular problem described in other forum postings (although there are a LOT of postings on this topic!).
Any help would be appreciated.I thought my testing server was the remote server and is always on as far as I know. I don't know how to turn it on or off.
Is there some other testing server that I should be aware of?

I have tried reseting the network settings and forgetting my wireless connection and re-connecting to it. I even backed up my phone on itunes and restored it, factory reseted it. Nothing seems to work.
Also after my upgrade to ios 8.1 my personal hotspot option under cellular data has disappeared.
Would you please help me out? I would really appreciate it.Hi..
Restart your router then restart the iPhone to test.

Network connection problems, please help!
I have had an iPod Touch (4th generation) for over a year now and it worked fine. Today, something went wrong with my network connection. One moment it says that I'm connected to a network, and a few seconds later it says I'm not connected... Then a few seconds later it's connected again. I have full wifi bars, and it does it throughout my whole house. The wifi symbol keeps going on and off. I tried turning my Verizon Westell Model 6100G Modem off and back on because this normally fixes my wifi connection problems. This didn't work. Then I tried turning my iPod off and back on. This didn't work. I tried turning the wifi off and back on. This didn't work. I tried forgetting my network and signing back in. This didn't work. I also tried resetting the network, and this didn't work either. I'm not having any connection problems with my laptop, it's working fine. It's only my iPod. I'm still able to use the wifi, but for a split second, it will not work. I'm not sure what else to do. It's very annoying! I'm going to see if it does this at other peoples houses with their wifi. Can any one tell me what's wrong and how I should fix it? My only theory is a broken antenna...Please help! Thanks!
I have two things you could try.
1. Plug your iPod into the host computer that which the network is based around because sometimes the network has trouble identifying a device if it has been a while since you plugged it into the computer.
2. Find some way to get your network information (IP address, Subnet Mask, Router, DNS numbers) from another device on the network (e.g. laptop). Then go to Settings > Wi-FI and find your router and tap the blue arrow to the right of the name and tap the tab that says "Static" and enter this information accordingly. Then exit back to the network names menu and re-enter your passcode for your network (assuming you have a passcode) -

WiFi Internet connectivity problems after upgrade to 10.8.4
After upgrading to MacOS 10.8.4 I am facing regular interruptions to my WiFi internet connectivity. Periodically the internet connectivity is lost and the only way to fix the problem is to turn WiFi off and on again. This happens frequently when I am downloading files at using big bandwidth (more than 1.5-2 MB/s). If I use assist me on the Network preferences tab, it displays an ISP error when the connectivity is down, however I am certain that I do nota have any kind of ISP or router issue since at the same time I have WiFi internet connectivity from my iPad mini, iPhone 4S and Samsung Galaxy S3. Therefore it should be a 10.8.4 issue

Lumia 900 Cellular Connectivity problem (AT&T) aft...
I've had a Lumia 900 on AT&T for about 5 months and have not had any connection problems. However, after the Tango update (OS *.8779.*; Firmware: *.12223), when I take my phone into work (which has no cellular reception normally) for an extended time and then take it outside it will sporadically not reconnect to the cell tower. It will show no connection forever. If I turn airplane mode on then off or turn off and then on the data connection, which seemed to fix similar problems before, I still get no connection.
The only solution is to restart my phone. One time it kind of hung on restart. The other time the phone froze up when I was trying to turn on/off the data connection. Restarting brings the cellular connection back. (Almost as if whatever software is controlling the cellular connection is crashing).
*I also installed the beta Nokia Counters program after the update -so that may be the problem too?
Has anyone else experienced this before. Is it a Tango issue, or a common issue that coincidentally started for me after the update?I am having a similar issues with Wifi & cellular connectivity Issues. In addition, am seeing that my Lumia 900's screen is turning black with no response from the power button or any other buttons (bottom buttons will be light though). I have to reset the phone by pressing volume power camera buttons. And one or two times today it had issues restarting cycling the Nokia logo, AT&T logo, then black screen about three to four times before it showed the Windows Phone logo to fully boot up.
Totally Disappointed. -
I have a mac 10.5.8 and it has been very slow lately. I often get the rainbow wheel when using it and recently I have had to restart the computer alot because it seems to freeze. The only other open program besides Safari is the finder which i cant seems to ever shut off. I'm not sure if this is an interent connection problem or if my mac needs servicing.
Please begin using 25 Ways to Speed Up Your Mac you will almost certainly find the cause there. The first place I'd look though is how much RAM your system has, if you never upgraded it that could be the problem. Macs ship with a minimum amount of RAM so it's possible a simple RAM upgrade would help. Use the article though and methodically go through the suggestions.
