Is there a way in Java to run an MS-SQL saved job?

I have a saved job called test, I can run the following in the Query
Analyzer and it runs fine:

SQL CODE
Exec msdb.dbo.sp_start_job @job_name = 'test'
END SQL CODE

I tried running this out of java, but get The specified @job_name
('test') does not exist.  Here is what I am doing.

I have a database connection before this and I know it works fine.

CODE
String t_job="test";
    PreparedStatement state = con.prepareStatement("EXEC
msdb.dbo.sp_start_job @job_name =?");
    state.setString(1, t_job);
    boolean rs_exists = state.execute();
END CODE

I have a few scripts and dts packages that I want users to run instead
of scheduling.  I can set these scripts and dts packages to run as SQL
jobs. It would be great if I could provide a list of these jobs in an
html form and pass the parameter off to a jsp such as this that would
run the proper job.

Thanks in advance.
