[Go-essp-tech] Report on wget behavior

[Drach, Bob]

We are getting the error ‘Bad version number in .class file’ when running with Java 1.5.0_26. The problem does not occur with Java 1.6. --Bob

 Hi all,

 I know everyone is working hard on things and that ESG is  evolving hourly, but here are some problems I encountered in trying to get the wget script to work:

 1. For the Mac, you must use "snow leopard" OS 10.6 in order to run Java 1.6.  Earlier operating systems (e.g., "leopard": 10.5.8) can only run Java 1.5, which is incompatible with what ESG needs to run MyProxy.  We need to warn users about this.

Assuming there are no 1.6 specific features, this is mostly likely just recompiling for 1.5. This should be really easy to solve.

Agreed. Neill indicated that 1.5 was what he used to compile this, so we shouldn't see any 1.6 dependencies. I just suggested on a separate thread that he verify this. Please let me know if you see any issues with using 1.5.




 2.  For the Mac, even when I was able to download the certificates, when I tried to run the wget script, I got the errors copied at the bottom of this email.  [Also I've attached the wget script.]  I think Bob has already reported this error.

 3.  I was unable to understand how to try the "other options" to run wget.  I read the following under "trouble shooting" after clicking on "Other options" to "obtain security credentials":

 "Run the following two commands on your Unix system to launch MyProxyLogon:
 wget http://cmip-gw.badc.rl.ac.uk/webstart/myProxyLogon/MyProxyLogon-ESG.jar -O $HOME/.esg/MyProxyLogon.jar
 java -jar $HOME/.esg/MyProxyLogon.jar -u <username> -h <myproxy-server>  "

 I presume that <username> is my ESGF username, but I have no idea what <myproxy-server> is.
 Can I run this on a mac (terminal window)?  -- that's not what it says, but I wondered.
 Don't you have to first download MyProxy something before executing these two commands?

The first wget command you pasted above downloads the executable for the MyProxy client. This is the same as what the WebStart executes.

On the <myproxy-server> value, it maybe worth displaying this on the Gateway for a user to copy/paste. It is auto-populated when WebStart works, so that information should be available.

 4.  Somewhere we should indicate what the requirements are for successfully downloading and executing wget using the Web Start method of launching MYProxyLogon.  I think they include:
 a) installation of java 1.6 (and if running on a mac, Mac 10.6 or higher).
 b) Elimination of firewall protections against opening "non-standard" ports.
 c) Web Start software installed and enabled on your browser.
 d) wget installed.

 We also need to indicate where one can get the required software.

 On systems easily accessible by me only c) and d) were satisfied.  On a Linux system I successfully downloaded data after addressing b)  (The other requirements were aleady met.)

 Note that perhaps a majority of mac users are still using Mac 10.5, so they will have a very difficult time.  [Of course pc folks running windows will be shut out.]  This is o.k. for now, I suppose.

 Best regards,
 Karl
