java - Handle absence of JNDI -


i have configured jndi reference in spring

<bean id="optionalbean" class="org.springframework.jndi.jndiobjectfactorybean">     <property name="jndiname" value="name"/> </bean>

but jndi property not configured. in case tomcat doesn't start.
how can tell spring jndi optional?

update: after adding lookuponstartup error:

nested exception org.springframework.beans.factory.beancreationexception: error creating bean name 'optionalbean': cannot resolve reference bean 'optionalbean' while setting bean property 'optionalbean';  nested exception org.springframework.beans.factory.beancreationexception: error creating bean name 'optionalbean':  invocation of init method failed; nested exception java.lang.illegalstateexception:  cannot deactivate 'lookuponstartup' without specifying 'proxyinterface' or 'expectedtype'

this should 

 <bean id="optionalbean" class="org.springframework.jndi.jndiobjectfactorybean" lazy-init="true">             <property name="jndiname" value="name"/>         </bean>

serialization - Convert Any type in scala to Array[Byte] and back -

i have following question: i have variable value in program declared value. i want convert value byte array.. how can serialize byte array , back? found examples related other types such double or int, not any. this should need. it's pretty similar how 1 in java. import java.io.{bytearrayinputstream, bytearrayoutputstream, objectinputstream, objectoutputstream} object serialization extends app { def serialise(value: any): array[byte] = { val stream: bytearrayoutputstream = new bytearrayoutputstream() val oos = new objectoutputstream(stream) oos.writeobject(value) oos.close stream.tobytearray } def deserialise(bytes: array[byte]): = { val ois = new objectinputstream(new bytearrayinputstream(bytes)) val value = ois.readobject ois.close value } println(deserialise(serialise("my test"))) println(deserialise(serialise(list(1)))) println(deserialise(serialise(map(1 -> 2)))) println(deserialise(seri
