InvalidAlgorithmParameterException

Thanks Brian.. In the prod, I have j2re1.5.0_05 wherein, In my dev, I have j2re1.5.0_06 which I think will not be a big difference.
I followed your suggestion and copied the security files from production to dev and tried.. I get the same error and also the beginning of the log says something like

InvalidAlgorithmParameterException

I am working on an old application with the following configuration. JRE 1.5_6 and Tomcat 5.5. I have to use this because the production environment has the same.

I ran this application 2 years back and it was working good .. I had to fix something in this application and had to set up everything now.. I did, when I started hitting the database, it throws the issue with the prime size.. I remember I posed the same topic few years back. The solution was to reinstall JRE. I did that today assuming the cacerts file under security folder would have been corrupted as I imported a certificate.. Can someone advise..

Tomcat

UnsupportedClassVersionError

I am using apache-tomcat 5.5 with the compatibility package in order to use that with JRE 1.4.1_17. We built the application 3 years back and I believe I was using the same configuration. When I tried to bring this application back in my system with the above configuration. I got the below mentioned error. Can anyone advise.

Because of this I am not able to bring this application up. Is there any issue with the version of JRE I use or I am not sure..

I tried installing JRE 5.0 but it ended up with a different error saying that 'JDBC driver is not found'

Can anyone advise

InvalidAlgorithmParameterException

I wrote a standalone program to analyze this issue. basically I am trying to connect to DB2.

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.Date;
import java.util.Properties;
import javax.activation.DataSource;
import com.ibm.db2.jcc.DB2BaseDataSource;
import com.ibm.db2.jcc.DB2Connection;
public class MyDAO {
public static String strDriver = "com.ibm.db2.jcc.DB2Driver";
public static void main(String args[]) {
Connection objConnection = null;
try {
System.out.println(new Date());
Class.forName(strDriver);
//objConnection = DriverManager.getConnection("jdbc:db2://suomt764.qintra.com:50000/DBJR","XXXXX","xxxxx");
Properties properties = new Properties();
properties.setProperty("securityMechanism", Integer.toString(com.ibm.db2.jcc.DB2BaseDataSource.ENCRYPTED_USER_AND_PASSWORD_SECURITY));
properties.setProperty("user","XXXXX");
properties.setProperty("password","xxxxx");
objConnection = DriverManager.getConnection("jdbc:db2://suomt764.qintra.com:50000/DBJR", properties);
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException sqle) {
sqle.printStackTrace();
}
System.out.println(new Date());
}
}

After executing this I get the following error
