Subject Compilation errors on generated Java code Thrift 0.8.0
Date Thu, 20 Sep 2012 01:01:56 GMT
hey
I was experimenting with a simple Thrift server and wanted to write
the client in java.
I ran the command
->thrift -gen java BLT.thrift
The generated java file Optimization.java shows the following error in
the Eclipse IDE.
Code snippet:
   public static class Client extends org.apache.thrift.TServiceClient
implements   Iface
Error:
The type TServiceClient cannot be the superclass of Client; a
superclass must be a class

public Client(org.apache.thrift.protocol.TProtocol prot)
    {
      super(prot, prot);
    }
The constructor Object(TProtocol, TProtocol) is undefined.
.....


I still went ahead and compiled it.
->mvn clean install
Optimization.java:[38,54] no interface expected here

I have the following dependency in my pom.xml

<dependency>
    <groupId>org.apache.thrift</groupId>
     <artifactId>libthrift</artifactId>
     <version>0.8.0</version>
</dependency>

-> mvn dependency:tree | grep -i thrift
[INFO] \- org.apache.thrift:libthrift:jar:0.8.0:compile

-> thrift -version java
Thrift version 0.8.0

I did find this thread but the recommended solution didnt work for me
http://stackoverflow.com/questions/2582085/maven-thrift-repository

Any help/insight  would be much appreciated.

Thanks
