Method Detail

compare

public static boolean compare(String me,
                              String you)

Compare two strings.

me - First value

you - Second value

Returns:

True if object equals else false.

lookup

public static <T> T lookup(Context context,
                           String name,
                           Class<T> clazz)
                    throws Exception

Lookup an object in the default initial context

Parameters:

context - The context to use

name - the name to lookup

clazz - the expected type

Returns:

the object

Throws:

Exception - for any error

locateTM

public static TransactionManager locateTM(String locatorClass,
                                          String locatorMethod)

The Resource adapter can't depend on any provider's specific library. Because of that we use reflection to locate the transaction manager during startup. TODO: We should use a proper SPI instead of reflection We would need to define a proper SPI package for this.

serialize

public static byte[] serialize(Serializable serializable)
                        throws IOException

Serialize the object into a byte array.

Parameters:

serializable - The serializable object

Returns:

The generated byte array

Throws:

IOException - For errors during serialization.

deserialize

public static Object deserialize(byte[] data)
                          throws IOException,
                                 ClassNotFoundException

Deserialize the byte array into an object.

Parameters:

data - The serialized object as a byte array

Returns:

The serializable object.

Throws:

IOException - For errors during deserialization

ClassNotFoundException - If the deserialized class cannot be found.

asString

public static String asString(Object object)

Return a string identification for the specified object.

Parameters:

object - The object value.

Returns:

The string identification.

maskUrlForLog

public static String maskUrlForLog(String url)
