Re: Java ans CW versions

Kevin Dorrell · ‎06-06-2005

I am having problems getting started with CW, and I don't have any experience yet to deal with it. Please pardon me if this is a bit of a newbie question.

My client PC has Java plugin 1.5.0-02, which is the latest version, as got from the Sun website. But whenever I try and start using CW (specifically when I try and set up the ANI, it tries to load Java 1.3.1 to the PC. Result: two Javas and a crash.

But if I don't start off with Java installed, then CW will not start at all.

I have RME with IDU 12.0, and Campus with IDU 11.0, and I thought these were compatible at least with 1.4.something. So why is it still trying to downgrade to 1.3.1?

Any ideas?

CiscoWorks with the updates you have should be looking for Java 1.4.1_02. It will accept no substitutes (either higher or lower version numbers). If you install the patch for CSCsa455551, you can then upgrade your Java to 1.4.2_06.

I don't know why the server would be trying to push the 1.3.1 version to you. I suggest installing 1.4.1_02 on the client manually and seeing what happens.

Thank you for that information. Do you know where I can download these older versions? The Sun/Java website seems to offer only the latest version.

Ciscoworks installs with 1.3.1 by default. If you need a higher revision of Java CW supports JRE 1.4.2_06b. There is a patch for this support in the CW LMS download center. Java 1.5 isn't supported. Install the new version on the CW server and your PC. All should work. Hope this helps.

Check on the CiscoWorks server under CSCOpx\htdocs\plugin

By the way, you might want to un-install 1.5

Hi Kevin

If you have any issues at all with Java versions in CiscoWorks, the easiest thing to do is remove all Java Plug-ins from the client machine/s and then browse to CiscoWorks. The CiscoWorks server will then automatically prompt you to install a Java Plug-in from the CiscoWorks server itself (no need to go to the Sun site). This is the easiest way of ensuring that you always have the plug-in which the CiscoWorks server wants you to use, because the Plug-in which you download will have come from the CiscoWorks server - Fully endorsed ;-)

Note: If you install any other versions of the plug-in on your client machines, whether you use them or not, you may experience further problems as the Java Plug-in's tend to conflict with each other ...

Hi Marcus,

Unfortunately, that does work either because I get an opening screen that reports Java disabled, and no other panes, so I have nothing to click on to provoke the download. I think you need at least some Java to get the opening screen in the first place. Unfortunately, I think my version of the broswer (6.0.2800.1106.xpsp2) was delivered without any Java support at all. I don't think M$ are allowed to integrate Java support any more for licencing reasons. And the Java site offers only 1.5. So I am in a Catch 22.

I must say, I am not finding this installation easy at all. I find it strange that Java is not backward comatible. What if I have another application that actually needs 1.5 on the client? Do I have to dedicate a machine to each application?

Hi Kevin

I just replicated your problem. I was also unable to login after removing the Java Plug-in - I've never seen this before, normally it just

takes you straight to the download page on web server ...

Anyways, I resolved the issue by installing JRE 1.4.1_02 from the following download page - I am using LMS bundle 2.2, so this is the

appropriate plug-in for this version

http://www.cisco.com/cgi-bin/tablebuild.pl/java

Try this and see how you get on

If you can't get to this page, let me know and I'll see if I can get it to you some other way ...

Also in answer to your other question, if you have client applications requiring different versions of Java, then yes, you will probably

need dedicated client machines ... This has been a cause of much angst for some time now ;-)

Cheers

Marcus,

I think we are on the right lines, but we are not there yet. Now that you have told me about that download page, I have rung all the changes, but still no luck.

Starting with no Java installed, if I pre-load the 1.3.1, it does not seem to link into the browser. The Java control panel (accessed from Control Panel) says it is enabled, but I see no menu item for the Java console, and CW says that Java is disabled, and refuses to give me the login pane.

Starting with no Java installed, if I pre-load 1.4.1_02, I can start CW OK, and log in OK. When I go to configure the ANI server, as soon as I click to set up "SNMP Parameters", the server tries to push 1.3.1, and the whole thing falls in a heap. I cannot understand why it is doing that. I have installed Update 1 and IDU 5.0 for both LMS and RWAN, so it should support 1.4.1-02.

I wonder, could it be related to XP SP2?

This installation is a nightmare.

I'll answer the last question in my posting: it's nothing to do with XP SP2. I'm getting the same effect on the client browser on the server machine, which is W2000 Server SP4.

I'm getting frustrated with this installation. Why is the server trying to push 1.3.1 on the client? Can it not see that it is running the Java?

Hi Kevin

I am assuming that you are running LMS bundle 2.2 ? Please let us know your setup if this is not correct

If you are running this version, then you should be able to run with JRE 1.4.1_02. I have XP SP2 on some clients also and they work fine ...

Have you tried accessing this server from any other clients. You may find that some work and some don't, which may help with troubleshooting. I wouldn't advise accessing the web interface from the server as it's just to slow, but again, you could try this for troubleshooting. If you have Firefox loaded, give this a try also ...

Check your settings for the Java Plug-in through control panel. Your settings should be as follows (tab-by-tab):

Advanced: Usa Java Plug-in Default, but you could try setting 1.3.1 or 1.4.1 depending on what have installed

Browser: Check the box for Internet Explorer

Proxies: User browser settings

Let us know your findings

Kind regards

Marcus

I have to say CiscoWorks 2000 is a nightmare. I have the exactly same problem as him. Ciscoworks 2000 is always push its java plugin 1.3.1, no matter what version java I installed already, then if I installed 1.3.1, the conflict happened, IE crashed and restarted.

Even if I cleared all java on my machine, and only install its 1.3.1 , then it will ask for a Microsoft java virtual machine, but MS doesn't support JVM any more, then I have to go to Sun to download the JRE for JVM. After I download no matter what version of JRE, the java conflict happens again.

I think the only solution is to upgrade this junk software now, I hope the upgrading can fix this problem.

Kevin Dorrell · ‎06-21-2005

David,

I respoved my problem in the end by reinstalling from scratch. I installed 1.4.2 on the client side from the outset, and then started the installation. The differences between this time and last time are that this time I have not insalled RWAN yet (LMS only), and I did not do the Apache update hat I found on the RWAN patch CD.

Bu note that I could not connect from the client to the server until after the last patch was installed on the server. I think the order (from memory) was basic installation, RME, IDU 5, Update 1, IDU 8.0, IDU 12.0., and only then did I install Campus Manager.

Hope ths helps.

You can have more then one version of Java installed, it's just that IE decides to force the use of the highest version installed. You have to go to Internet Properties and then Advanced and then halfway down you will see a Java (SUN) portion, uncheck the box. I have several versions of Java installed and don't have problems. With that box checked, that version of Java will be used for all applets. Java is backwards compatible but sometimes programmers write for what works and not what is supported. Then you have bugs and the removal of some features to make way for others.
