xml - Soap Signing in Clojure -


i working api requires soap calls signed. have looked documentation java on how sign soap calls using programming java xml digital signature api.

i consistently running following error java.lang.illegalargumentexception: no matching method found: newcanonicalizationmethod class org.jcp.xml.dsig.internal.dom.domxmlsignaturefactory.

i know issue sending parameters newcanonocalizationmethod. following flow per java, still running issue.

here code.

(let [fac (xmlsignaturefactory/getinstance "dom")        dm (doto (.. fac (newdigestmethod (digestmethod/sha1) nil)))        bk ""        ref (.. fac (newreference bk dm))        cm (canonicalizationmethod/inclusive)        c14 c14nmethodparameterspec        in (.. fac (newcanonicalizationmethod cm c14))])

here full function code: have started process of creating signature section per site: http://www.oracle.com/technetwork/articles/javase/dig-signature-api-140772.html

(defn create-signature   []   (let [fac (xmlsignaturefactory/getinstance "dom")         dm (doto (.. fac (newdigestmethod (digestmethod/sha1) nil)))         bk ""         ref (.. fac (newreference bk dm))         cm canonicalizationmethod/inclusive         c14 c14nmethodparameterspec         si (..              fac              (newsignedinfo                (..                  fac                  (newcanonicalizationmethod                    cm                    c14nmethodparameterspec))                (..                  fac                  (newsignaturemethod                    (signaturemethod/rsa_sha1) nil))                (.. java.util.collections (singletonlist ref))))         ]         ))

if run reflect on factory, response:

{:name newcanonicalizationmethod,  :return-type javax.xml.crypto.dsig.canonicalizationmethod,  :declaring-class  org.jcp.xml.dsig.internal.dom.domxmlsignaturefactory,  :parameter-types  [java.lang.string   javax.xml.crypto.dsig.spec.c14nmethodparameterspec],  :exception-types  [java.security.nosuchalgorithmexception   java.security.invalidalgorithmparameterexception],  :flags #{:public}}

the solution issue generate of java methods in custom java class. issue java method looking type of parameter. code says generate using (java type)null, doesn't compile in clojure.

i using website generate xml signing link.

after creating custom class, compiled , imported clojure project.

lesson learned: when working java classes, best use pure java instead of java interop.

Optimising Firebase database by automatically overwriting data -

in firebase app have following structure: posts latest all users can write posts > latest . want limit entries 20 posts save space in database. , posts beyond 20 unnecessary never shown on homepage. how can limit posts 20, when user writes posts > latest posts @ end drop off (be deleted) automatically? this sample should you. you need : const max_log_count = 20; exports.removeold = functions.database.ref('/posts/latest/{postid}').oncreate(event => { const parentref = event.data.ref.parent; return parentref.once('value').then(snapshot => { if (snapshot.numchildren() >= max_log_count) { let childcount = 0; const updates = {}; snapshot.foreach(function(child) { if (++childcount <= snapshot.numchildren() - max_log_count) { updates[child.key] = null; } }); // update parent. removes children. ...

each grid cell can have more 1 customtemplate loaded. have directive holds watcher on model_col_field listen cell updates on scroll when dom rows updated , recompile celltemplate . without watcher , $compile rows repeat on scroll, showing same set of rows. is there more angular way of approaching or way improve performance? relevant controller code: create gridoptions.data & gridoptions.columndefs : var customtemp = '<div ng-repeat="opt in grid.appscope.colvalueoptionsmodel" ng-init="tempstring=model_col_field.clazz+opt.key;"><comparison-directive dbo="model_col_field" attobj="opt" fff="grid.appscope.getattributetemplate(tempstring)" /></div>'; $scope.gridoptions.columndefs = [ { name:'yindex',pinnedleft:true,celltemplate: customtemp, displayname:'index'}, { name:'col1',celltemplate: customtemp}, { name:'col2',celltemplate: c...
