java - Spring - Do all beans get processed? -

-

i have beans.xml file ldap application writing. allowing user choice of several ldapcontextsource(s). each 1 have different bean, e.g.

<bean id="ldaptemplate" class="yyy.ldaptemplate">       <constructor-arg ref="contextsource1" /> </bean> <bean id="contextsource1" class="xxx.ldapcontextsource">       ... </bean> <bean id="contextsource2" class="xxx.ldapcontextsource">       ... </bean> <bean id="contextsource3" class="xxx.ldapcontextsource">       ... </bean>

you can see 1 of these context source beans gets instantiated, because 1 referred ldaptemplate bean. however, when run application, spring log messages in stdout provide information each context source, though 1 depended on.

jan 25, 2011 11:56:36 org.springframework.ldap.core.support.abstractcontextsource afterpropertiesset info: property 'userdn' not set - anonymous context used read-write operations jan 25, 2011 11:56:37 org.springframework.ldap.core.support.abstractcontextsource afterpropertiesset info: property 'userdn' not set - anonymous context used read-write operations jan 25, 2011 11:56:37 org.springframework.ldap.core.support.abstractcontextsource afterpropertiesset info: property 'userdn' not set - anonymous context used read-write operations

my questions are:

(1) spring doing context sources not referred / depended on? should never instantiated in application, , worries me spring providing log information each of these beans.

(2) should comment out context source beans not used in application? consequences of leaving them uncommented? standard practice?

thanks,

maybe check out lazy loading of beans. here relevant explanation spring 2.5.x docs...

the default behavior applicationcontext implementations eagerly pre-instantiate singleton beans @ startup. pre-instantiation means applicationcontext eagerly create , configure of singleton beans part of initialization process. thing, because means errors in configuration or in surrounding environment discovered (as opposed possibly hours or days down line).

however, there times when behavior not wanted. if not want singleton bean pre-instantiated when using applicationcontext, can selectively control marking bean definition lazy-initialized. lazily-initialized bean indicates ioc container whether or not bean instance should created @ startup or when first requested.

for sake of completness here example...

<bean id="contextsource1" class="xxx.ldapcontextsource" lazy-init="true"/>

java - SNMP4J General Variable Binding Error -

i trying use snmp4j snmp bulkget. when ever use snmp4j make call returned responseevent error says "general variable binding error" , data returned equal null. to debug: print out, console, exact oid , version number using in snmp4j. use printed out data snmpwalk on command line. valid results. know sending snmp4j correct pdu correct oid, version number, max repititions, etc. i have used snmp4j , code wrote succesffuly monitor other devices years. don't know different time. leaving me stumped. why "general variable binding error?" causes error? ideas debug? can reproduced? if so, first action should using wireshark or microsoft network monitor capture network packets. my guess agent gives generr response, not surprising, http://www.ietf.org/rfc/rfc1157.txt

the following code takes xmlnode data type , populates dataset object xmlnode content. write dataset's content file. public void populatedataset(xmlnode node) { xmlnodereader reader = new xmlnodereader(node); dataset ds = new dataset(); ds.readxml(reader); system.guid guid = system.guid.newguid(); string name = string.format("{0}{1}_{2}.xml", utility.xmloutputpath, utility.xmloutputfilename, guid.tostring()); //need write "node empty" file if xmlnode object empty of null ds.writexml(name, xmlwritemode.ignoreschema); } the problem encountered 1 scenario not write content file. how determine if xmlnode object null or empty? you can check if node parameter null or has innertext or innerxml properties null or empty, when enter method before creating xmlnodereader .
