JDBC problem with string

Hello Everybody,

I have written one program in java2 to write the data
in postgresql. I am storing one integer and one string
in the database. When i read the string from the file
it is proper. But when i want to store it, it gives
the
following exception:
java.sql.SQLException: ERROR:  parser: parse error at
or near ""  

I am not able to detect the error. Can any one run the
code and correct the problem?
When I assign the string test1 some fixed value (say
"foo") and run the code, then the program works fine.

Here is the code:
