I have been trading sometime both Demo and Live using a custom Jforex API build. For some reason last Monday a week ago the application would no longer connect or trade with the account it stopped at approximately 8:35 GMT Monday 23.02.2015. So far I have been unable to figure it out. Does anyone have any experience or suggestions. I am using Java 1.7 and JForex -API-2.6.72.jar. Work fine for weeks even months even on Monday the 23rd until 8:35 GMT.

Any suggestions or experience anyone can share with me will be kindly appreciated.

Cheers
Nevis

Thanks for the suggestion.

I am using JForexAPI-2.12.6, DDS2-jClient-JForex2.43.2, dds2-common-2.5.70.

While executing "ClientFactory.getDefaultInstance()" Its generate the following exception and so IClient object could not able to connect.

Then I have changed the version of dds2-common to 2.5.6, then I got the following exception

"Exception
java.lang.NoClassDefFoundError: com/dukascopy/transport/common/msg/strategy/FileMngRequestMessage"

Would you like to help me on this ?
Would you like to share me which version of jar file I need to use?

Thanks,
Satya

Please remove dependency on dds2-common. It is redundant. Only JForexAPI-2.12.6 and DDS2-jClient-JForex2.43.2 are required.

Thanks

I have removed dds2-common. After that I am getting the following exception. The exception arises on the below statement.
try {
client = ClientFactory.getDefaultInstance();
}
catch(Throwable e) {
e.printStackTrace();
}

Hi support Team,

Would you like to help me on this? I am waiting for your response. I have tested this with Java 1.7. Should I test this with java 1.8?

Thanks,
Satya

NoClassDefFoundError usually is due to problems with IDE project library configuration. ProtocolMessage is located in transport-common jar.
One option to test the project could be to run mvn clean install from command line.
