Jquery Json parser showing invalid character error for jersey rest webservice response -

i'm creating json rest webservice mediatype property

@get @produces(mediatype.application_json) public issues getallopenpoints() { 

i'm using jackson jars creating json response. not creating json manually still when trying parse response jquery. throws invalid characher error.

$.parsejson(result); 

do need encode or escape data in objects before returning rest webservice. whats point of using auto response conversion jackson.

i believe know problem in json parsing still looking reason. problem due structure of object graph have.

• first designed xml manually.
• then generated schema xml
• then used eclipse create java objects xsd.

below xml started with..

<issues>   <issue>     <product>xxxx</product>     <datereported>xxxx</datereported>     <summary>xxxx</summary>     <status>xxxx</status>     <responsibleperson>xxxx </responsibleperson>     <targetcompletiondate>xxxx</targetcompletiondate>     <completiondate>xxx</completiondate>     <application>xxxx</application>     <priority>xxxx</priority>     <comments>         <comment>             <date>xxxxx</date>             <description>xxxxx</description>         </comment>         <comment>             <date>xxxxx</date>             <description>xxxxx</description>         </comment>     </comments>   </issue>     ......      ...... </issues> 

issue class contains object of type comments , comments object contains list of object type comment. if had started creating java object first instead of xml, have kept list of "comment" in issue class rather 1 comments object.

now resulting in following json.

{    "issue": [       {          "product": "xxxxx",          "datereported": "xxxxx",          "summary": "xxxxx",          "statu‌​s": "xxxxx",          "responsibleperson": "xxxxx",          "targetcompletiondate": "xxxxx",          "‌​completiondate": "xxxxx",          "application": "xxxxx",          "priority": 1,          "comments":{                 ‌​"comment":[                 {                    "date": "xxxxx",                    "description": "xxxxx"                 },                 {                    "date": "xxxxx",                    "de‌​scription": "xxxxx"                 }              ]         }       }    ] } 

if edit json , try parse following json in sample js file. works fine.

{    "issue": [       {          "product": "xxxxx",          "datereported": "xxxxx",          "summary": "xxxxx",          "statu??s": "xxxxx",          "responsibleperson": "xxxxx",          "targetcompletiondate": "xxxxx",          "??completiondate": "xxxxx",          "application": "xxxxx",          "priority": 1,          "comments": [             {                "date": "xxxxx",                "description": "xxxxx"             },             {                "date": "xxxxx",                "de??scription": "xxxxx"             }          ]       }    ] } 

but first json valid object representation. why exception thrown in parsing ?
