There was a problem hiding this comment.
The setActiveTab method on lines 26-32 generates JavaScript code with a potential issue. Line 28 references activeTab as a variable in the JavaScript without quotes, but activeTab is a Java parameter. The first script should likely use ' + activeTab + ' to properly quote the variable name. Additionally, the logic appears to remove the active class from an element with id activeTab (unquoted), which may not work as intended.

There was a problem hiding this comment.
The control flow logic in the remove-from-cart section (lines 64-82) appears malformed. There is an if statement at line 68 that checks if (itemQty == 1), followed by an else at line 71, but then another else block at line 78 without a corresponding if. This creates invalid Java syntax. The logic should be restructured to properly handle the three cases: quantity equals 1, quantity greater than 1, and the removal logic.

The getConnection method checks if the static connection is null and throws an exception if so, but then returns null instead of the connection object. This will cause NullPointerException in callers like UserServiceImpl and BookServiceImpl when they attempt to use the returned connection. The fix ensures the method returns the valid connection.

There was a problem hiding this comment.
The SQL query strings are constructed using string concatenation with constants, which makes them difficult to maintain and verify. Additionally, the registerUserQuery uses positional parameters (VALUES(?,?,?,?,?,?,?,?)) without specifying column names, making it fragile if the table schema changes. Consider using parameterized queries with explicit column names or a query builder to improve maintainability and clarity.

The retrieveFromHttpServletRequest method uses Long.parseLong(phNo) without validation, risking a NumberFormatException if the phone parameter from the request is not a valid long string. This could crash the method unexpectedly. Adding a null check and try-catch block would make it more resilient to bad input.

The indentation in setter methods appears to use 8 spaces instead of the standard 2 spaces per indentation level. Consider adjusting the indentation to use exactly 2 spaces per level for consistency with Java code style guidelines.

Database connections are obtained but not explicitly closed, potentially leading to resource leaks, especially if DBUtil's connection is not truly static or shared.

Retrieving price as an integer truncates decimal values, but the Book model uses double for price, potentially causing incorrect data representation.

The catch block for SQLException is empty, swallowing exceptions that could indicate DB issues, leading to silent failures where methods return null or empty collections instead of throwing StoreException as declared.

The update operations do not check if any rows were affected, always returning SUCCESS even if the book ID does not exist.

The method getBooksByCommaSeperatedBookIds() constructs a SQL query by directly concatenating the commaSeperatedBookIds parameter into the query string at line 153. This creates a SQL injection vulnerability. Use parameterized queries or validate/sanitize the input instead of string concatenation.

The InputStream 'input' is not closed after use, potentially causing resource leaks. Refactor to use try-with-resources.
If getResourceAsStream returns null, prop.load(input) will throw NPE. Add if (input != null) check.

The static field prop is declared without the final keyword. Since this field is initialized once in the static initializer and should not be reassigned, consider declaring it as static final Properties prop to make the intent clear and enable compiler optimizations.
