We are testing web services of an information system and this system is running on websphere and all the web services request and responce goes through data power - Using SOAPUI we are trying to automate the whole process.
There are certain certificates involved in this process of authentication when request and responce goes through datapower - such as KeyStore and TrustStore.
I am using the Trial version of SOAPUI and in the SSL settings I find options to speficy KeyStore file and password but I am not finding options to specify TrustStore file and password.
I tried sending the request without TrustStore but getting responce with the following error 
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
         <faultstring>Internal Error</faultstring>
Could any one please help me on this - I want to know exactly where should I put the TrustStore file and password in the SOAPUI ?
Thanks in advance,
