我不能發現錯誤

嗨我做了一個if查詢，並且這個問題發送到服務器。但是，服務器將只接受2個數字和一個十進制數字（99.9），但我必須計數到100，服務器總是給我一個錯誤。你知不知道我可以怎麼捕捉這個錯誤，以至於我的軟件無論如何Counts爲100.它不能輸出到服務器。該程序只能運行。他不讓它在99再次停止，並繼續倒計時所以當他正值99，然後100我不能發現錯誤

公共靜態無效的主要（字串[] args） {

boolean positive = true; 
    int counter = 0; 


    while (true) 
    { 

     if (counter >= 99) 
     { 
      positive = false; 
     } 
     if (counter <=-99) 
     { 
      positive = true; 
     } 

     if (positive == true) 
     { 
      counter ++; 
     } 
     else 
     { 
      counter --;  
     }

這是我的「軟件「例外是：

所以我希望你能幫助我。

這就是我的主要

您的'main'方法和web應用程序之間有什麼關係？ –

聯繫遠程服務器的代碼在哪裏？ – Carlo

添加'spring-mvc' lib至少 –

爲您發佈的錯誤，你需要find and add the spring-tx library到類路徑中。您可以將其添加到/WEB-INF/lib。

但是，我沒有看到您發佈的異常和您發佈的代碼是如何相互關聯的。

我的軟件將數據發送到服務器。我在一個客戶端上工作，服務器不是從我這裏來的。做這個服務器的人已經確定你只能發送一個兩位數的nummer，並且可以在小數點後面傳遞一個數字。但是我想要做的就是捕獲錯誤，以便進一步使我的程序即使服務器報告錯誤100。然後，他應該輸出一個文本輸出，數字100不被服務器接受，但他仍應該繼續返回值數數。（100）99 98 .... – MQBuild

@ user3297407我希望您明白，您遇到的錯誤與您向我們顯示的代碼完全無關。 –

好的。我無法用錯誤查詢來捕捉它？（例外） – MQBuild

服務器可能缺少依賴項：spring-tx。

您可以下載JAR或您的項目依賴此添加：http://mvnrepository.com/artifact/org.springframework/spring-tx

索蒂里奧斯Delimanolis是正確的，也請避免把，而（真），因爲它是一個無限循環，你可以把例如while（positive），這會使計數器遞增，直到達到99.
