Anyone having problems with Java applications?

[pauls01]

Hello all. I have the latest version of java on a brand new fresh install of Windows Seven with all the available windows updates installed. I use several java based programs for work (From Nortel & Cisco) but they do not work properly. When I click to open any of these applications, they hang for a minute or two and eventually open, and then when they do open, they are completley sluggish and don't respond well. On my XP machine, these apps run instantly.

Is there anything else I can try??

Hi there

make sure the JRE is the same level that your work requirements are - sometimes having the latest jre and sdk completely hozes up a system if you need to connect to corporate apps with several releases earlier.

Another get around is to run a small XP as a Virtual machine or try "XP Mode".

Until some of the corporate apps are on W7 older java apps could present a problem.

I connect to SAP via a "SAPGUI" which still needs an almost pre-historic level of the JRE 1.4.2 !!. Any later version and the whole app just randomly crashes.

Cheers

Hi Jimbo,on further inspection, it doesn't do it on just these apps, it really does it anything that needs Java. When I tried the apps I previously mentioned, a process starts called javaw.exe and takes up 50% of the CPU until the program eventually loads and javaw.exe usage goes back to zero. With other java apps (I tried the Facbook Photo Uploader), a second instance of java.exe starts and again takes up 50% of CPU, and grind the computer to a halt until it eventually loads and then everything runs normally again.

Hi there
I'm Not a JAVA expert but you could try unintalling the whole JAVA environment, then install again and try a small "Hello World" app witj the java interpreter run from the command line --(normally someting like javac.exe then your source file.

If that works then try for the Visual J 2010 from Ms - you can get the single user versions for free - with the Visual composer.

See what happens there.

I think also if you have a 64 bit OS installed you need both the 32 and 64 bit java libraries etc.

Cheers

Hi Jimbo, I have re-installed and it continues to freeze on every java app, then after a few minutes will load correctly. This isn't a showstopper but is somewhat irritating.

I am having the exact same problem, it has nothing to do with java or the programs. I reverted to a save point before any of the windows updates were done and java works fine. But after any install of update java will stop working. I tried asking on the actual win7 forums, but like typical microsoft they shrug it off as being javas fault and not their own.

Hi Atlas, thanks for letting me know. I did install all the available Windows Updates after doing a fresh install of Ultimate, so I never had a working java. I really hope they find a fix.

 

[Atlas elite]

Yeah, it should of made a save before the updates, atm that clean 7600 install is only time java works for me.

I just want to say that I have similar problems. However I am not completely convinced that it is a Java problem. I have Win7 Pro and the newest Java installed (1.6_16 I think). Java apps like Freemind or Jabref cannot be used - they are slow as hell. But I have a very specific similar problem in MS OfficeXP: when I type Ctrl+F to open the search dialog, the animated pop-up pops up very slowly. So I was wondering if maybe the problem is related to the graphics driver (ATI Mobility Radeon X1300). But there is no driver besides the one from Windows Update so I cannot check.

Since all Java apps have problems I think we need an update here. But from whom? MS or Java? And why do some people seem to have no problem with Java apps? What's the difference? I use a Thinkpad T60, no "special" software installed, just basic drivers and typical office software...

I've been having the same problem. I've found that the original release of JRE 1.6.0 works. It's still slow to start up, but applications still run. With any of the subsequent releases, I can't even access the control panel applet. This must be a rare problem, because I can't seem to find any solutions beyond uninstalling, using a cleanup program, then reinstalling, yet the problem persists. BTW, I'm running 32-bit Windows 7 Home Premium.

 

[Spock]

Thanks for your post, that's interesting. So you say install JRE 1.6.0 (no updates) and all the applications run normally? Is it necessary to use a cleanup program like you said? Which one did you use?

Unfortunately installing JRE 1.6.0 is a very bad "solution" since JRE is a highly security critical software which demands for installing new updates. Running an old version is a security risk for your PC. On the other hand I am very interested in running those Java apps again... and unfortunately no one (from MS or Java) seems to be aware of the problem.

 

[nhf7170]

So far as I can tell, all of the java apps (really just JDownloader) I use run under 1.6.0, although there is a delay. It is also the only version for which I can get the control panel applet to appear. I don't really need to use any cleanup programs for this. I just need to uninstall all other versions of java. I know there are security issues, but it is the only way I can get java to work. I'm still trying to see if I can find a better solution, but so far I've come up empty. I'm surprised that this problem isn't more common.

 

[Spock]

Very strange - I still have the current Java 1.6.17 installed and the Control Panel applet shows no problems, I can start it as expected. But all Java-apps run extremly slowly. You're completely right - I cannot understand why this issue isn't more common.

I found the SOLUTION:
if you have more than 1000 fonts installed in your computer JRE crash irremediably, because it scan all fonts installed when javaw.exe process run, for solved that, you must be unnistall all no system fonts that you have (it is an unnecessary unistall the adobe fonts) after that you must unnistall all Java enviroments and delete all java and sun folders in your computer, install JRE 6 update 17 after do you do this ( remember restar you computer after install JRE6), and ta, da¡ all java APP works perfect y had 10347 fonts installed, and my system crahs in a mortal way, but with this, java works perfectly, currently i have 342 fonts intalled, y expect that this solutions works for all.

sorry for my bad english

I just tried Freemind and it works fine.

Use Windows Installer CleanUp Utility to delete all java installs.

Delete \Program Files (x86)\Java and delete any folders and files that start with java.

Open Internet Explorer and go to java.com and install java. Do the same with FireFox and check the java install.

I do that, and don't work to me because the fonts problems, afterall is a posibly solution if the fonts don`t are the problem, thanks for you help belikexp.

Thank you so much for solving my problem. This was driving me mad since I upgraded to Windows 7. I don't know how you could have known that, but thanks. I had about 8,000 fonts installed. Now my computer is so much more responsive. Rep for you.

 

[Spock]

Uhm... I have 207 fonts installed. I cannot believe this is the problem...? What exactly am I supposed to do? Uninstall all these fonts? But I think I need most of them occasionally... So can I reinstall them after doing what you suggested? Or do I have to live with just basic system fonts?

And is it really necessary to install Java in Firefox AND Internet Explorer?

 

[pauls01]

Spock, I had around 5000 fonts installed. I have followed the instructions above and it has absolutely fixed the problem. This is not a solution for me however, as I work in graphic design and need these fonts a daily basis.

Anyway, all my apps now work, with absolutely no delay.

Thank you to Erion for finding the solution but someone needs to bring this to the attention of Sun/Windows.

 

[Spock]

Use Windows Installer CleanUp Utility to delete all java installs.

I don't understand that one - Windows Installer CleanUp Utility does NOT uninstall any program as far as I know. It simply cleans up residuals from uninstalled msi-Installer-based software.

One question here - I only have the Win7 standard fonts and the Office 2007 standard fonts installed, which are 207. When I uninstall them, how can I bring them back? Since erion did not have the problem with 342 fonts, I don't see why I shoud start uninstalling my fonts. But if I try - how can I bring the Win7 fonts back?

I think there must be another cause for the problem. Erion has no problem with 342 fonts, I do have the problem with 207...
