java - problem with arguments when running a jar using reflection -


I tried to apply the method to run a jar using reflection with getMethod but arguments called to pass Having run into trouble with the given method: 

  string mainClass = myprog.Run; String [] args = new string [2]; Argos [0] = "-a"; Argus [1] = "-C ./config/param.xml" Class Loader Classloader = CreateClassPath (); // method call the setContextClassLoader (classLoader); Class & lt ;? & Gt; TheClass = classLoader.loadClass (Main Class); TheClass.getMethod ("main", string []. Square). Ivok (tap, object);

I get this error: 

  [java] java.lang.reflect.InvocationTargetException [java] sun.reflect.NativeMethodAccessorImpl.invoke0 on ( Native method) SunkreflectkNativeMethodAccessorImplkinvoke ([Java] on NativeMethodAccessorImpl.java:39) [Java] sun.reflect.DelegatingMethodAccessorImpl.invoke (on DelegatingMethodAccessorImpl.java:25) [Java] java.lang.reflect.Method On. Call (Method.java:597) eu.keep.util.JarRunner.run (Unknown Source) [Java] because at [Java]: java.lang.RuntimeException: not present in the config file 'param.xml' folder Is '/ home / user / ./config' [Java] on dioscuri.DioscuriFrame. & Lt; Init & gt; (Unknown source) [java] dioscuri.DioscuriFrame.main (unknown source) [java] ... 5 more  at

As you can see from Stacktrace, that folder '/ home Trying to access the file 'param.xml' from / user / ./config '.

Obviously, if there was no space between '/ home / user /' and './config', then it would be al-El properly.

I'm confused with the fact that I String [] args arguments hardcoded in and the second one is "-c ./config/param.xml" and it looks like dir where The app is running, i.e. / home / user /, is mixed with ./config/, but with a space in between ??

Any ideas what is happening?

Maybe if we do main method, and in particular the way the argument is understood, we can help you better ...

Note that when you type the command java ... Run your main square with -a -c ./config /param.xml , then you have 3 arguments in your main (string [] args method: 

  public static zero main (string [] args) {for (string s: arg } {System.out.println ("->" + + '' '));} ...

will be displayed: 

  -> & gt; -a '- & gt; - C '- & gt;' ./config/param.xml '

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. 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...
