java - spring 3: inject a dependency from a library? -


i developing project , using 3rd party libraries. let's use library gives me object extobj. in project have class myobj, uses extobj. how can configure spring 3 inject extobj in myobj?

i tried research topic on internet, didn't find straight answer. use xml configuration , maybe (?) @autowired, not @ejb or @inject

thanks in advance!

update guess was:

<bean id="myobj" value="me.myobj">   <property name="extobj" value=" ... ??? ..."> </bean>

so, don't know should put value. guess that's reference external object goes. spring can reference objects have been defined/configured in spring. so:

<bean id="extobj" value="ext.lib.extobj"> <bean id="myobj" value="me.myobj">   <property name="extobj" value="extobj"> </bean>

is configuration right?

first need define bean extobj in application context (an xml file or @configuration class). eg. if extobj has constructor taking string can define bean way:

<bean id="extobj" class="ext.lib.extobj">     <constructor-arg value="somestring"/> </bean>

to define myobj can use constructor injection:

<bean id="myobj" class="me.myobj">     <constructor-arg ref="extobj"/> </bean>

or setter injection:

<bean name="myobj" class="me.myobj">     <property name="extobj" ref="extobj"/> </beans>

if use setter injection myobj needs have setter setextobj. if use constructor injection myobj needs have constructor taking instance of extobj class.

Eclipse formatter for java ending braces -

i know if it's possible setup eclipse format braces using banner style. we're working code uses banner style formatting , keep consistent within team version control reasons. here's example of banner style formatting not familiar: public class foo { //------------------------ public static void main (string[] args) { boolean condition = true; try { if (condition) { system.out.println ("condition true"); } else system.out.println ("not condition"); } catch (exception ex) { // handle errors } } //------------------------ } update: name style ratliff. experiment java->code style->formatter preferences. "banner style" seems poor use of space given outline view , quick outline functionality.

ruby - Nesting modules inside of a Rails eninge gem -

what proper syntax nest child modules within parent module being isolate_namespace rails engine gem? # lib/myengine/engine.rb module myengine class engine < rails::engine isolate_namespace myengine # def ... end end for example. parent module myengine , child module blog. myengine share common domain, crud, taggable, searchable, etc, keep gem code dry , isolated main app (myapp), while inheriting isolated namespace , engine. are either of 2 approaches correct? refactor advice? # # lib/myengine/blog.rb module myengine module blog # def ... end end # b # lib/myengine/blog.rb module myengine class engine < rails::engine isolate_namespace myengine module blog # def ... end end end option a. correct, should lib/my_engine/blog.rb . can read more ruby & rails naming conventions here . further, if want put more modules or classes under blog namespace put them in folder lib/my_engine/blog , nest them under myengine::bl...

php - Why I am getting the Error "Commands out of sync; you can't run this command now" -

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...
