Get Client Certificate by Servlet

843811Feb 25 2003 — edited Mar 16 2003
hi everyone,

i am using servlet to get the details of the client certificate though the Browser IE, however i got the Exception.
java.lang.ClassCastException: [Ljava.security.cert.X509Certificate

I found that it is failed to get the correct object in the following code:
(X509Certificate)request.getAttribute( "javax.servlet.request.X509Certificate" )

i have printed out the object by using the following code:
Object obj=null;
PrintWriter out = response.getWriter();
out.println("Client Certificate Attribute " + attributeName + ", type \"" + obj.getClass().getName() );

the result:
Client Certificate Attribute javax.servlet.request.X509Certificate, type "[Ljava.security.cert.X509Certificate;

As i have seen some post claims that this is the bug of Tomcat 3.X version
but i have already used Tomcat4.1.18
Also i have try to use Netscapte6.2, but it also failed.

What can i do about it???
Thanks in advance!!!

well .. i hv tried this .. it works but why 1=2 at the end..the statement works even without this..

Because that create table command is just to create table without copying data.
I think in your question, you said you want to copy data from another table with same structure. Thus why Jith created an empty table with the same structure.

beware of constraints while creating the copy table.
creation will create only NOT NULL constraints. primary key, foreing key and unique constraints will not be created with this query:"create table copy_trial as select * from trial;"

By "copy data from schema", you mean table by table? Of course it is possible, if you have permissions on the other schema table.
insert into my_table
select * 
from other_schema.table

Dear Sarma

How about copy data from one schema to another schema, which they are different Server(computer)?

Will it be possible?

Thanks a lot :>

Yes you can do it by create a db link (database link)
then write query like

insert into my_table
select *
from other_schema.table@(db link name)

You need to have corresponding object privileges to do the same when you are trying to copy data from the table of another schema or another database.

Create a private database link in case if you want ti copy data from another database

With similar table structure you can copy data from one schema to another
schema
login to target database1


Condition1 Append data
copy from scott/tiger@database2 append emp using select * from emp;

Condition2 create new table
copy from scott/tiger@database2 create emp using select * from emp;
