java - Troubleshoot JSP nullpointer exception problem -


I'm doing, I'm looking at a very old project and try to recover some of the projects which JSP pages of this project Is related to zero indicator exception. The JSP page is throwing an exception like a zero pointer like the sample given below. 

  /e2fo/tools/user/search/searchUser.jsp exception was thrown: java.lang.NullPointerException com.ibm._jsp._searchUser_5F_TA._jspService (_searchUser_5F.java:207)

now that reproduce the problem are not eligible to serve, only need to put me up to see the exception, where there might be problems. As I understand, JSP pages are compiled into Java Srwolet and therefore the exception is displayed in the stack file .java servlet file is an intermediate file and we do not get to see it, I'm running 6.1 Web page. In this case, how to determine the JSP file from the server or how to set the row number?

The last time I went to this, the intermediate file was run when I saw. I had to introduce a deliberate compiler error did, JSP to go around it and run it again. When it kills that exception, then Servlet saves the source so that you can correct the code error.

I was trying to just put down to: 

  & lt; % Novariable.toString (); & Gt%;

I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
