Getting a 404 error when instantiating a core java class in a servlet -

-

i building web application in java , when trying instantiate core java class servlet class , use methods of class, getting 404 error. have been trying figure out reason long couldn't find any.

code: servlet class:

public class supportpage extends httpservlet { public void doget(httpservletrequest request, httpservletresponse response) throws ioexception, servletexception {     printwriter out = response.getwriter();     // when remove part, app runs fine.     jirarest jirarest = new jirarest();     string key = null;     try {         key = jirarest.createissue(12403, 10000, "test", "test");     } catch (jsonexception e) {         e.printstacktrace();     } catch (urisyntaxexception e) {         e.printstacktrace();     } catch (httpexception e) {         e.printstacktrace();     }     out.println("<html>");     out.println("ticket key: "+key +" created");     out.println("</html>");     return; }}

java class:

public class jirarest { public string createissue(integer projectid, integer issuetypeid, string summary, string description)         throws jsonexception, ioexception, urisyntaxexception, httpexception {     jsonobject fields = new jsonobject();     fields.put("project", new jsonobject().put("id", projectid.tostring()));     fields.put("issuetype", new jsonobject().put("id", issuetypeid.tostring()));     fields.put("summary", "test");     fields.put("customfield_10004", "testdvf");     //fields.put("description", "this test.kindly ignore!");      jsonobject issue = new jsonobject();     issue.put("fields", fields);     system.out.println(issue);      stringentity se = new stringentity(issue.tostring());     se.setcontenttype("application/json");     httpclient client = new defaulthttpclient();     httppost post = new httppost("https://jira.endurance.com/rest/api/latest/issue?os_username=abc&os_password=xyz");     post.setentity(se);     post.addheader("accept", "*/*");     post.addheader("connection", "keep-alive");     httpresponse response = client.execute(post);      string json_string = entityutils.tostring(response.getentity());     system.out.println(json_string);     jsonobject obj = new jsonobject(json_string);     return obj.getstring("key");  }}

the java class making rest calls. url trying access: localhost/projectname/support. when remove jirarest class usage in supportpage class, works fine. appreciated.

edit: adding stacktrace http://pastebin.com/fdxmghu5

ensure have packed required , dependent libraries war file, or copy them under container shared library folder.
