Runtime exception java.lang.ClassNotFoundException on executing Stored Proc

Question

I am getting the below error when I try to execute a stored proc in Pointbase from weblogic.
java.sql.SQLException: The external "DbLog::insLog" routine had the following runtime exception "java.lang.ClassNotFoundException: DbLog"
import java.sql.*; import com.pointbase.jdbc.*; public class DbLog { static Connection conn = null; static Statement m_stmt; static Statement l_stmt; static CallableStatement m_callStmt = null; public boolean logPreAuth() { try { String I_URL = "jdbc:pointbase:server://localhost:9093/weblogic_eval"; conn = DriverManager.getConnection(I_URL, "PBSYSADMIN", "PBSYSADMIN"); /*String SQL_CREATE_PROC = "CREATE PROCEDURE insLog(IN P1 VARCHAR(30))" + " LANGUAGE JAVA" + " SPECIFIC insLog" + " DETERMINISTIC" + " NO SQL" + " EXTERNAL NAME \"DbLog::insLog\"" + " PARAMETER STYLE SQL"; m_stmt = conn.createStatement(); m_stmt.executeUpdate(SQL_CREATE_PROC); m_stmt.close(); */ Commented out because it throwed error saying, The routine "INSLOG" in schema "PBPUBLIC" already exists in system table SYSROUTINES. m_callStmt = conn.prepareCall("{ call insLog(?) }"); m_callStmt.setString(1, "Success!!"); m_callStmt.execute(); } catch (Exception e) { logger.error("Error in logPreAuth method" + e); } return true; } public static void insLog(String test) { try { l_stmt = conn.createStatement(); l_stmt.executeUpdate("Insert into logs values('" + test + "')"); l_stmt.close(); conn.close(); } catch (Exception e) { } }
Please let me know how to solve this.

I setted the classpath in commEnv.cmd as follows,
set POINTBASE_HOME=%WL_HOME%\common\eval\pointbase
set POINTBASE_CLIENT_CLASSPATH=%POINTBASE_HOME%\lib\pbclient57.jar
set POINTBASE_CLASSPATH=%POINTBASE_HOME%\lib\pbembedded57.jar;%POINTBASE_CLIENT_CLASSPATH%;C:\bea\user_projects\workspaces\work1\utility\build\classes
set POINTBASE_TOOLS=%POINTBASE_HOME%\lib\pbtools57.jar
My DbLog class in the path, C:\bea\user_projects\workspaces\Work1\util\build\classes\net\local\util\common
FYI, net\local\util\common is the package.
But when I try to execute the page which calls RequestFilter.java, I am getting the following error,
Error 500--Internal Server Error
java.lang.NoClassDefFoundError: Could not initialize class net.local.util.common.DbLog
Please find the code below,
