Help: TWSStart Problem after IB TWS Upgrade

Postby Spaceant » 08 Apr 2014

Hi,

I have just upgraded IB TWS upgrade. Well, it was wired that as it indicated it was not a successful upgrade. Therefore, I restalled it after unstallation of IB TWS. Although I can start IB TWS manually. Hwever, TWSStart doesn't work after the upgrade. Error message is :
Fatal Error: one of the following jar files is missing from the classpath:
jfreechart-1.0.9.jar
jcommon-1.0.12.jar
Please make sure you run the application from the shortcut that was
installed on your desktop or on the Start menu when you upgraded.
The application will now terminate.


Does anyone experience problem like this before? How can I fix it?

Thanks!

This may not be the answer you are expecting, but personally I had nothing but a lot of problems with IB. Primarily connectivity or orders somehow being in "limbo" between MC and IB. And a lot of research indicated it was on the IB side. I'm not using another broker via TT and those problems have not surfaced at all. I don't believe I am the only one who would say this. So perhaps you may want to look into other options, especially if you are auto-trading where connectivity and proper order flow is absolutely critical.

the latest TWS comes with only one jar file: total.2012.jar
this contains everything. so there is a startup script where the old jar files are referenced, replace it with the new one. i had the same issue with ibcontroller

Hi wegi,

Could you explain more about how to "replace it with the new one"?

Hi,

i tested the latest TWSStart, and it works with the latest TWS Version.

the eventlog shows this line for me:

Code: Select all

13:55:12 - Info : " -cp jts.jar;total.2012.jar -Dsun.java2d.noddraw=true -Dswing.boldMetal=false -Dsun.locale.formatasdefault=true -Xmx768M -XX:MaxPermSize=128M jclient/LoginFrame C:\Jts"
there you can see the total.2012.jar.
Try in TWSStart: configuration -> java settings.
Press the button behind Java ClassPath for Trader Workstation or IB Gateway.
After, there should be "total.2012.jar" in the input field below. Or add it manually.
Then it should work, if not uninstall and reinstall tws start.

Do you know, if twsstart keeps the tws allways up ?
