Java EE (Java Enterprise Edition) General Discussion

Hi,

I want to call a web service from an EJB and need a certification to do so.
I imported this cert into a keystore and put it into my JAR file (which is in the
EAR). How do I have to set javax.net.ssl.trustStore?

System.setProperty(
   "javax.net.ssl.trustStore",
   "keystore");

nor

System.setProperty(
   "javax.net.ssl.trustStore",
   "/keystore");

worked :( I always get this Exception:

Caused by: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty
        at java.security.cert.PKIXParameters.setTrustAnchors(PKIXParameters.java:183)
        at java.security.cert.PKIXParameters.<init>(PKIXParameters.java:103)
        at java.security.cert.PKIXBuilderParameters.<init>(PKIXBuilderParameters.java:87)
        at sun.security.validator.PKIXValidator.<init>(PKIXValidator.java:54)
        ... 89 more

Any ideas? Thanks!
