jQuery ajax ERHALTEN gibt, 405-Methode Nicht Erlaubt

Kann man nicht machen-javascript - /Ajax-Aufrufe auf verschiedenen domains (ohne einige ernsthafte kludging). Was wir getan haben, für die dies in der Vergangenheit ist die Schaffung eines lokalen jsp proxy, nennen wir mit unserer javascript-aber ist nur ein pass-through an die remote-URL.

Ist hier einige Beispiel-JSP-code, der in der Nähe zu dem, was ich verwendet habe, zu schlagen, ein SOLR-Instanz zurückgeben JSON.

final String ENCODING = "UTF-8"; //this is the default unless specified otherwise (in server.xml for Tomcat)
