Hi,
I am trying to use a Tomcat webapp as a RMI client.
For the test purposes, my RMI server
resides on the same machine. When I use a Tomcat
webapp as a client, I consistently get a
ClassCastException, while if I use a plain java class
for the client, it works flawlessly.
Following is my client code used in the servlet and
the plain java class.
System.setProperty("java.rmi.server.codebase",
"file:/path/to/stubfile/");
try {
//(line: 141)
TestInterface testIf = (TestInterface)
Naming.lookup("//localhost/Test");
result = testIf.testMethod();
} catch (Exception e) {
servlet.log(e.getMessage());
e.printStackTrace();
}
I am using:
JDK-1.4
tomcat-4.1.12
>From the stack it looks like the stub file is located,
but it cannot relate it
with the interface file.
java.lang.ClassCastException: Test_Stub
