问题 I have an application , contains a broadcastReceiver which listens to all new received SMS . If any new SMS received this BroadcastReceiver starts a background Service which runs GPS and return the coordinates , this coordinate retrieving needs a new thread to be run , in the Service class there is no getApplicationContext() so I used 'getContentBase()' for starting the new thread this is the code ((Activity)getBaseContext()).runOnUiThread(new Runnable() { ((Activity)getBaseContext())

ClassCastException Proxy36 cannot be cast to SessionImplementor after Hibernate/Spring 4 upgrade

由 此生再无相见时 提交于 2019-12-06 08:19:07
EDIT: I am not asking what a ClassCastException is. I am asking what is causing it in DetachedCriteria under this specific configuration of Spring 4/Hibernate 4. I'm trying to upgrade some legacy code to Spring 4/Hibernate 4 and I've hit a wall, as Google isn't turning up much. I am trying to run a JUnit test on a very simple Hibernate repository, and it is failing with java.lang.ClassCastException: com.sun.proxy.$Proxy36 cannot be cast to org.hibernate.engine.spi.SessionImplementor at org.hibernate.criterion.DetachedCriteria.getExecutableCriteria(DetachedCriteria.java:84) at com.my.app.rest

Android LinkedHashMap deserializing as HashMap, causes CCE error

由 随声附和 提交于 2019-12-06 06:10:53
I'm attempting to pass a serialized LinkedHashMap between activities, and getting a confusing result/error when I deserialize the object. I serialize the object as follows: Bundle exDetails = new Bundle(); LinkedHashMap<String, Exercise> exMap = new LinkedHashMap<String, Exercise (workout.getExercises()); exDetails.putString(WORKOUTNAME, workout.getWorkoutName()); exDetails.putSerializable(workout.getWorkoutName(), exMap); iComplete.putExtra("wName", exDetails); startActivity(iComplete); That seems to work fine, the problem shows up in the next activity: Bundle exDetails = getIntent()

Eclipse ClassCastException when trying to expand XML layout for Android

由 隐身守侯 提交于 2019-12-06 04:07:49
问题 I am new to java, eclipse, and android development, so I may be missing something simple although I have checked basic stuff like spelling several times. Because there is no number picker control (such as that used in the date picker) in the public Android SDK, the conventional wisdom is to "clone and own" the control that exists in the Android source. In an attempt to do that, I have copied the code for NumberPicker into my project and its dependency, NumberPickerButton. I have also copied

Java.lang.reflect.Proxy returning another proxy from invocation results in ClassCastException on assignment

由 时光毁灭记忆、已成空白 提交于 2019-12-05 22:26:59
问题 So I'm playing with geotools and I thought I'd proxy one of their data-access classes and trace how it was being used in their code. I coded up a dynamic proxy and wrapped a FeatureSource (interface) in it and off it went happily. Then I wanted to look at some of the transitive objects returned by the featureSource as well, since the main thing a FeatureSource does is return a FeatureCollection (FeatureSource is analogous to a sql DataSource and featurecollection to an sql statement). in my

UISelectMany in ui:repeat causes java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to java.util.List

由 萝らか妹 提交于 2019-12-05 18:50:11
I have used the HashMap method for binding a list of checkboxes to a Map<String, Boolean> with success. This is nice since it allows you to have a dynamic number of checkboxes. I'm trying to extend that to a variable length list of selectManyMenu . Being that they are selectMany, I'd like to be able to bind to a Map<String, List<MyObject>> . I have a single example working where I can bind a single selectManyMenu to a List<MyObject> and everything works fine, but whey I put a dynamic number of selectManyMenus inside a ui:repeat and attempt to bind to the map, I end up with weird results. The
