g++ 4.1.x compile error with template

[agarkar]

Hi,
I am not able to compile this with gcc4.x , it works fine with
gcc3.2.2.
When I include txbase.h in .C file and build
g++ -c filename.C
I get following error. Line 56 is List <TxRule *>   commonValidations;
in txbase.h
Based on my reading I will need to add a line in txbase.h to define
List class, But I am not able to get correct signature
what will make gcc happy.
/home/eps/eps_port/te/src/EGIFT/TxFrm/TxInc/txbase.h:56: error: ISO C++
forbids declaration of 'List' with no type
/home/eps/eps_port/te/src/EGIFT/TxFrm/TxInc/txbase.h:56: error:
expected ';' before '<' token
/home/eps/eps_port/te/src/EGIFT/TxFrm/TxInc/txbase.h:57: error:
'List' has not been declared
/home/eps/eps_port/te/src/EGIFT/TxFrm/TxInc/txbase.h:57: error:

Thanks in advance.
