Java ClassCastException when generating WSDL in Eclipse? -

-

i trying create new web service in eclipse (bottom up, apache axis 1, tomcat 6), warnings before attempt , error after.

error:

iwab0398e error in generating wsdl java:  java.lang.classcastexception: org.apache.axis.encoding.ser.beanserializer cannot cast org.apache.axis.encoding.serializer

here use serializable:

public class integrationutils extends utilities implements java.io.serializable {     private static final long serialversionuid = 7515033201857603982l;

summary of warnings: lot of warnings have classes used web service class not having default constructors.

here warnings:

thanks help!

you classcastexception, whenever have duplicate jars or jar-files same class-files in it. in case different axis version too. problem typically occures, when tomcat instantiates axis-class , sends instance application. application on other side can uses own jars (packaged war or ear). , because of posibility of multi classloader hirarchie in web- or java ee-container can run different webapps there own jar-files-versions @ same server @ same time.

but how solve it? well, search these classes (shown in stacktrace) in jars of tomcat , web-application , check, 1 used instantiate axis-requests/-responses. easiest solution is, remove relevant jar web application , compile code against jar's of runtime environment (your tomcat). if tomcat-jar-versions not usable case, try patch server-jars. alternative solution can different configuration of web-application/server controll classloaders.

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
