swing - NoDefClassFoundError in Java - 


  सार्वजनिक शून्य सेटपर (विंडो पैरेंट) {if (true) {this.parent = ((abc.InvestRegPropertySeize) माता-पिता); } Else {this.parent = ((cde.InvestRegPropertySeize) माता पिता); }}   
 उपरोक्त में जब मैं इस कोड को संकलित करता हूं, तो इसे सफलतापूर्वक संकलित किया गया है और अनुपालन के बाद मैं 'cde.InvestRegPropertySeize' की क्लास फाइल को मैनुलली हटा देता हूं और जब मैं इस कोड को follwing त्रुटि को चलाने की कोशिश करता हूं हो रहा है।  
  NoDefClassFoundError of'cde.InvestRegPropertySeize '  
 लेकिन मुझे लगता है कि ऐसा नहीं होना चाहिए क्योंकि शर्त हमेशा सच है और' सीडीई की कोई ज़रूरत नहीं है। चलने वाले समय में इन्वेस्टराइजप्रॉपर्टी साइज़ 'क्लास फ़ाइल, तो ऐसा क्यों हो रहा है कृपया मुझे समाधान बताएं।   
 
 
 एक ही रास्ता ऐसा कुछ करने के लिए उपयोग करके है। अपने कोड में दो डाट निकालें, इसलिए वर्गों को रनटाइम पर हल नहीं किया जाएगा। फिर क्षेत्र और कॉल विधियों तक पहुंचने के लिए प्रतिबिंब का उपयोग करें। प्रतिबिंब शक्तिशाली है, लेकिन कोड बहुत पठनीय नहीं है और यह कुछ प्रदर्शन ओवरहेड के साथ आता है। इसलिए इसे प्रयोग करने से पहले दो बार सोचें।

python - Assemble mpeg file unable to play in mediaplayer -

I am currently working on a school project and I think that is to gather some problems with the MPEG file I The scope of my project is: 1) Split the MPEG file into pieces of many fixed sizes. 2) Collecting some of them and leaving some part. Problem 1: When I run the file in the media player, it will play the video until it reaches that segment which I left Give it Example: Chunk = ["yui_1", "yui_2", "yui_3", "yui_5", "yui_6"] Duration of each segment: 1 second * If you think I have left the "yui_4" section. * If I went to collect all the parts except "yui_4", then the video will play the first 2 seconds before being hanged throughout the period. Problem 2: When I gather the first part off the part, it is unable to run the full MPEG file is. Duration of each piece: 1 second Example: wheel = ["yui_2", "yui_3", "yui_4", "yui_5", "yui_6"...

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
