From your comment above, the actual line that is failing is:
st.executeUpdate("INSERT INTO CUST_RALLY_TEAM_MEMBER " + "VALUES projectValue,columnValue)");
Here, you are literally passing this string to Oracle:
INSERT INTO CUST_RALLY_TEAM_MEMBER VALUES projectValue,columnValue)
You need to pass the values of those variables (you're also missing an open parenthesis:
st.executeUpdate("INSERT INTO CUST_RALLY_TEAM_MEMBER VALUES ('" + projectValue + "','" + columnValue + "')");
This assumes that the cust_rally_team_member contains only these two columns, if not (and as a best practice, even if it does), you should be specifying the columns to be inserted into. Assuming the column names are also "projectvalue" and "columnvalue", then the statement would be:
st.executeUpdate("INSERT INTO CUST_RALLY_TEAM_MEMBER (projectvalue,columnvalue) VALUES ('" + projectValue + "','" + columnValue + "')");
Note, too, that prepared statements are a good approach for a process such as this. It eliminates the risk of SQL errors if the values contain a single quote, reduces the risk of SQL Injection attacks, and improves performance by compiling the statement only once.
