[gt-user] signer information does not match??

[sary357]

Dear all,

I tried to ru nthe following codes 

FileInputStream in = new FileInputStream(fileName);             
int length = in.available();
f ( length > 10000 ) length = 10000;
byte [] data= new byte[length];
int read = in.read(data);
ExtendedGSSManager manager = 
(ExtendedGSSManager)ExtendedGSSManager.getInstance();
GSSCredential cred=manager.createCredential(data,                               
ExtendedGSSCredential.IMPEXP_OPAQUE,                            
GSSCredential.DEFAULT_LIFETIME,
                null, // use default mechanism - GSI
                GSSCredential.INITIATE_AND_ACCEPT);
return cred;

However, I got the following error:

Caused by: java.lang.SecurityException: class 
"org.globus.common.CoGProperties"'s signer information does not match signer 
information of other classes in the same package
        at java.lang.ClassLoader.checkCerts(ClassLoader.java:775)
        at java.lang.ClassLoader.preDefineClass(ClassLoader.java:487)

....

What does this mean? I have complied again but in vain. I don't know whether 
it's about my JDK version. I use JDK1.5. Does anyone have any idea?



Cheers,
