java - JMockIt security exception signer information does not match -

-

when running jmockit , trying mock instance in testng loaded signed jar error along lines of (in case of jetty server):

failed configuration: @beforeclass startserver java.lang.securityexception: class "javax.servlet.filterregistration"'s signer information not match signer information of other classes in same package     @ java.lang.classloader.checkcerts(classloader.java:943)     @ java.lang.classloader.predefineclass(classloader.java:657)     @ java.lang.classloader.defineclass(classloader.java:785)     @ java.security.secureclassloader.defineclass(secureclassloader.java:142)     @ java.net.urlclassloader.defineclass(urlclassloader.java:449)     @ java.net.urlclassloader.access$100(urlclassloader.java:71)     @ java.net.urlclassloader$1.run(urlclassloader.java:361)     @ java.net.urlclassloader$1.run(urlclassloader.java:355)     ...

the dependency order in pom correct, , without mocks tests run fine. tips java securityexception: signer information not match not here.

is there workaround?


here sample test up, should produce error. in case start entire container integration test:

public class myservlettest {     private final server server = new server(port);     private mockup<openidauthenticationprovider> openidap;      @beforeclass     public void startserver() throws exception {         final servletcontexthandler context = new servletcontexthandler(servletcontexthandler.sessions);         context.setcontextpath("/");         context.addservlet(myservlet.class, "/my/*");         this.server.sethandler(context);         this.server.start();         this.openidap = new mockup<openidauthenticationprovider>() {             @mock             void $init(final userdao userdao) {}         };     }      @test     ... }

the openidauthenticationprovider called within myservlet , instantiated during startup, although i'm not sure matters.

the corresponding part in pom.xml looks this:

<dependencies>     <dependency>         <groupid>org.eclipse.jetty</groupid>         <artifactid>jetty-servlet</artifactid>         <version>9.0.3.v20130506</version>         <scope>test</scope>     </dependency>     <dependency>         <groupid>org.eclipse.jetty</groupid>         <artifactid>jetty-server</artifactid>         <version>9.0.3.v20130506</version>         <scope>test</scope>     </dependency>     <dependency>         <groupid>javax.servlet</groupid>         <artifactid>servlet-api</artifactid>         <version>2.5</version>         <scope>provided</scope>     </dependency> </dependencies>

one way use jmockit deactivate certificate check. since jmockit (and other mocking frameworks) work via instrumentation, class can modified. here example how mock part of classloader, causes troubles:

@beforesuite public void deactivatecertchecker() {     new mockup<classloader>() {         @mock         void checkcerts(final string name, final codesource cs) {}     }; }

mind though, not fix running program has signing issues, effect available during test runs, when mocking has been instrumented.

Issues changing the value of an element in an array in matlab -

i'm trying create program sum n-1 , n-2 numbers create n , store value in array. currently, output (assuming numdisp > 2 ) num1 , num2 , 0 , 0 , 0 ... size of array correct, i'm having issues reassigning elements. num1 = input('input first integer of fibonacci sequence: '); num2 = input('input second integer of fibonacci sequence: '); numsdisp = input('how many integers display? --> '); list = zeros(numsdisp,1); list(1) = num1; list(2) = num2; if (numsdisp <=0) disp('value must integer greater zero.') elseif (numsdisp == 1) disp(num1) elseif (numsdisp == 2) disp(num1) disp(num2) else disp(num1) disp(num2) index = 3:numsdisp disp(list(index)) list(index) = list((index-1)) + list((index-2)); end end example input: 3 3 4 corresponding output: 3 3 0 0 you aren't printing out final result, intermediate steps. in for loop, printing list(index) updating value, rather updat...

php - MySQLi binding parameters in a prepared statement doesn't work unless inserted after "WHERE" -

i have php code pulls info database. uses prepared statement, works fine written below: <?php $n = '5'; if ($stmt = $connection->prepare("select title items id = ?")) { $stmt->bind_param("s", $n); $stmt->execute(); $stmt->bind_result($title); while ($stmt->fetch()) { echo $title; } $stmt->close(); } ?> and let's echo "batman". however, when move placeholder here: "select ? items id = 5" and change: $n = 'title'; instead of echoing "batman", echoes "title". not possible use placeholder select parameter? what have done this: select "title" items id = 5 you cant use prepared statement bindings identifiers, parameters.
