Compile and Runtime Exceptions

Hi all,
What are Compile-time Exceptions and Runtime Exceptions.
and by the way,
What are Checked Exceptions and Unchecked Exceptions
Thanks in advance

http://java.sun.com/docs/books/tutorial/essential/exceptions/index.html
There isn't really such a thing as a "compile time excepitons." "Exceptions" are when something goes wrong at runtime. You can, of course, get compilation errors because your code doesn't follow Java's syntactical rules, but we don't call those exceptions.
And of course, if your compiler is written in Java, then compile time for you is runtime for the compiler. (The compiler is a Java program that's running.) So it could throw an exception. But that's not your code.

Java Compiler gives "Runtime" Exception, hahaha

What wrong with it. Some Java compiler versions give error, others may not but I am not sure what is the maximum no. of dimensions a java array can take. The compiler, while compiling, threw an exception and requested to report the bug at java site,, haha

Yes, you are right. It throws an Stack Overflow exception, but... WILL EVER SOMEONE NEED AN ARRAY THAT LONG?. Maybe the developer make their languages to some "reasonable" limits.

Writing a compiler with Compiler and Runtime class

I am writing a simple compiler that uses the Compiler class to compile a program and the Runtime class to execute the java file. However, I am having trouble located the .class file, and displaying the results when the file is executed. The following code is a segment of my program. Does anyone have any suggestions?
try
               saveFile();
               //Process p = Runtime.getRuntime().exec("javac "+fileName.getName());
          Process p = null;
               //JOptionPane.showMessageDialog(null,"Compile Message "+p.getErrorStream(), "Message:
               ",JOptionPane.ERROR_MESSAGE);
               s = fileName.getName();
               int truncStart = s.indexOf(".java");
               compiled = java.lang.Compiler.compileClasses(s);
               s = s.substring(0,truncStart);
               JOptionPane.showMessageDialog(null,"Compile File "+s, "Compile File : ",JOptionPane.ERROR_MESSAGE);
               p = Runtime.getRuntime().exec("java "+s);


OK, I think I need a delay between my compile stmt and my exec stmt. If anybody has had a similiar problem please let me know how you resolved it. Here is my code so far.
try
               saveFile();
          Process p = null;
               s = fileName.getName();
               String[] command = {"javac","c:/"+s};
               try
               JOptionPane.showMessageDialog(null,"Compile File "+s, "Compile File : ",JOptionPane.ERROR_MESSAGE);
               p = Runtime.getRuntime().exec(command);
               catch (Exception q)
               JOptionPane.showMessageDialog(null,"Compile Error:"
+q.toString(),"Error!",JOptionPane.ERROR_MESSAGE);
               int truncStart = s.indexOf(".java");
               s = s.substring(0,truncStart);
               String[] command2 = {"java", "c:/"+s};
               try
               JOptionPane.showMessageDialog(null,"Exec. File "+s, "Exec. File : ",JOptionPane.ERROR_MESSAGE);
               p = Runtime.getRuntime().exec(command2);
               catch(Exception y)
               JOptionPane.showMessageDialog(null,"Exec Error :"+y.toString(),"Error!",JOptionPane.ERROR_MESSAGE);
               }

How to see the compilation and runtime errors in NW 2004s

Hi
I have developed some J2EE application and deployed it in a NetWeaver 2004s, some problems has occurred when I try to run this application.
Where can I see the errors stacktrace for J2EE applications ? Is there any log ? I have already checked the std_server0.out and I didn´t find it there.
By the way.. my SAP NetWeaver Application Developer is not validating the JSP syntax after I save the JSPs.

Hello Michel,
The exceptions will appear in ./j2ee/cluster/server0/log/defaultTrace.<#>.trc provided that the application is written to use the SAP logging API.
Regards,
Nathan

XMLBeans compile and runtime issues (outside weblogic)

Hi,
I've a couple of probs with XMLbeans.
1. I'm unable to generate a jar file from the built in compiler. It seems to
look up some wierd path for javac and complains it can't find javac.exe
2. I generate the java file using the -srconly flag in scomp.cmd
Iincorporate the generated java files (and the schemastype files) into my java
project and try to compile a simple helloworld type application for the easypo
example included.
When I try to load a sample easypo xml file by parsing into a PurchaseOrderDOcument,
I get a schema resource not found error.(Index.xsb)
There doesn't seem to be much documentation from BEA for using in standalone environments(outside
weblogic workshop). APache hasn't released anything new either.
Thanks
BR

I managed to get the schema compilation working.
The schema compiler seems to be looking for a java system property named java.home
and then uses that to append "../bin/javac.exe" to it.
The following command line option(in scomp.cmd) solves this problem.
scomp -out myeasypo.jar easypo
modified scomp.cmd file
@rem Schema compiler
@rem
@rem Builds XBean types from xsd files.
@echo off
java "-Djava.home=c:/j2sdk1.4.2_01/bin" -classpath ../lib/xbean.jar com.bea.xbean.tool.SchemaCompiler

CHECK V RUNTIME EXCEPTION

Hi there
What is the difference between a checked and runtime exception?

All exceptions are checked and
are required to be caught in a try-catch block unless
they are descended from RuntimeException.
You aren't required to catch runtime exceptions in a try-catch block while you are required to catch checked exceptions. Oh, really? I had a question like this when my company gave us a Java exam. Almost every one got that one wrong.
The question was whether a thrown checked exception must eventually
be caught and handled by the program.
Consider this:
public class ExcTest
public static void main(String[] a)throws IOException
throw new IOException();
Here, a checked exception is thrown and not handled by the programmer.

Runtime exception with ADG when compiled with ANT

Hi,
We are using Advanced Data Grid in our project and it compiles and produces a correct SWF file when compiled using the licensed FlexBuilder. This work fine for the development environment, but for the testing and staging environments we use ANT to automate the build process of both Flex and Java components.
When the swf is built using ANT, we get a runtime exception when the page containing the ADG is accessed in web browser. The exception is
TypeError: Error #1007: Instantiation attempted on a non-constructor.

On forums of slackware there was a reference towards the program "free" which is being executed from /usr/bin/free whereas the program on slcakware resides in /bin/free or vice versa. Creating a ymlink should solve the problem. Dunnow (yet) if that works

Runtime error after successful compile and link with cl.exe

Finally, got the configuration for cl.exe and link.exe right and got a successful compile and link to produce a dll. Then ran the main method of my Java class. The main method calls the constructor, and loading the class runs the static block which loads the native dll. I get one of those error files of the type hs_err_pid4064.log. The file is as follows:
# An unexpected error has been detected by Java Runtime Environment:
# Internal Error (0xe06d7363), pid=4064, tid=3576

The dll I'm wrapping is C++ VC++ compiled.
Would like to know what I do to trouble-shoot this error and hope to fix it?
Jim

Using Java print statement was able to show that the my JNI dll was being loaded and that the problem was in the first call to one of my JNI functions. Then by using "DebugBreak()" in that function and gradually moving it down line by line through the function was able to isolate the line causing the problem. Unfortunately it is the line where I call a function from the dll I'm wrapping. See newer thread.

Can you please differentiate between compile time and runtime?

hi,
I heard many of them speaking about complie time and runtime. I sometimes feel they talk about it but they themselves don't know about it.
Please help me out.
Thanks in anticipation

Deepa Datar

Just remember, runtime means you are running the program. Compile time means your are in the process of building the program ("javac bla.java").

Referenced native libraries getting pre-compiled and then throwing exception

Hi I have an issue in the universal app. I am referencing Nokia.Graphics.Imaging.dll and WindowsPreview.Media.Ocr.dll in the universal app project. Everything compiles and runs on every device I tested it with. The problem is that after some time NGen kicks
in and pre-compiles my DLLs, including the native ones. These DLLs then get corrupt and next time I run the app I get BadImageFormatException due to an attempt to load the <nativelibrary>.ni.dll. Is this a bug of NGen? When I delete these <nativelibrary>.ni.dll
files the app runs again.

Hi, unfortunately, I was not able to simulate this behavior in another project so far. Here
http://uloz.to/xRShw487/precompiled-zip are NGENed files from our application (_not_working folder) and from a filter-manager sample (_working from different_app). As you can see for some reason Lumia.Imaging.ni.dll
in our app has only 796kB, while from the other app it has 1235kB.
The NGEN log file looks ok to me:
03/23/2015 15:18:24.272 [11796]: 1>    Compiling assembly C:\Program Files\WindowsApps\app\Lumia.Imaging.Managed.DLL (CLR v4.0.30319) ...
03/23/2015 15:18:24.350 [11796]: ngen returning 0x00000000
03/23/2015 15:18:25.334 [24168]: 1>    Compiling assembly C:\Program Files\WindowsApps\app\WindowsPreview.Media.Ocr.winmd (CLR v4.0.30319) ...

03/23/2015 15:18:25.725 [8036]: ngen returning 0x00000000
Once I delete Lumia.Imaging.ni.dll and WindowsPreview.Media.Ocr.ni.dll, the app starts working again. Lumia.Imaging.Managed.DLL seems to be OK and does not cause any troubles, maybe because it is managed, while both of the problematic DLLs are native already.
Hi LVolf,
>>I am referencing Nokia.Graphics.Imaging.dll and WindowsPreview.Media.Ocr.dll in the universal app project
How did you add these references in your project? Basically, the NuGet package is the easiest way, for example:
See the
NuGet documentation for all the ways you can download and install the NuGet package in your project. To install the package from within Microsoft Visual Studio, do the following:
1.In Visual Studio, select PROJECT | Manage NuGet Packages.
2.In the Online section, select nuget.org. Search for
Microsoft.Windows.Ocr.
3.Click Install.
4.Select BUILD | Configuration Manager to change the build configuration of your project from
AnyCPU to x86, x64, or ARM.
5.If Intellisense does not work after you have installed the NuGet package, unload and reload the Visual Studio project. In Solution Explorer, right-click the project and select
Unload Project. Then right-click the project again and select
Reload Project.

How can I compile and run other java classes from within an application?

Hello there everyone! I really hope that someone can help me. I am writing a program that must be able to compile and run other java classes that are in different files, much like development environments like Kawa or Forte allow you to do.
There has to be a way of doing this ( I hope!! ), but i can't seem to find it!!
I have tried using this command to compile:
Runtime.getRuntime().exec ("c:\\programs\\javac className.java");
...and this one to run:
Runtime.getRuntime().exec ("c:\\programs\\java className");
...but neither works!!! I can compile and run classes that are in the same file as my application, but I can't get it to work at all for files in different directories or files.
PLEASE, PLEASE, PLEASE help me - i've run out of ideas, and i need this to be working in 3 days!!!
Thank you very much for any help anyone can give me, I really appreciate it!! Thanks again!!
Adrian ( ...in distress!! )

public class JavaCompiler{
   public static void main(String[] args)throws Exception{ //sorry bout the laziness
      if(args == null || args.length != 1){
         System.out.println("Usage: java JavaCompiler MyClass.java");
         System.exit(0);
      String className = args[0];
      Runtime rt = Runtime.getRuntime();
      Process p = rt.exec("javac " + className); //consider setting cpath for this
      p.waitFor();
      //now try to run after it is done.
      p = rt.exec("java " + className.substring(0, (className.length() - ".java".length()));
      p.waitFor();
      //do some other stuff
}This should get you going. You may consider looking into the System.getProperty() method in order to determine the type of OS it is running on in order to findo out what command to run. I know that the sun tool listed above is nice, but by my understanding the sun tools provided are not guaranteed to stay the same. I'm no expert on this matter, but that is one of the reasons there is no API documentation for those tools. Also, I don't believe those tools come packaged with the JRE. (Of course if you are making an IDE it will be expected that the user has an sdk installed. Good luck with figuring this thing out.

Reg: Runtime exception occurred during application mapping

Dear SAP Gurus,
This is Amar Srinivas Eli working currently on SOAP to SOAP Scenario on PI 7.1 Server.
I Would like to inform you that I have done all steps regarding DESIGN and CONFIG and also regarding SERVICE REGISTRY part successfully.
While Testing the data in the WS Navigator by giving the input parameters I am getting an error that
*<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>*
*- 
- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">

<SAP:Retry>N</SAP:Retry>
</SAP:Error>
These are the steps I did while implementing..
1. Importing the XSD's successfully
2. Developed the design and config part and also checked nearly 3-4 times regarding both REQ and
    RESPONSE Mappings.
3. I already checked the link of WSDL once again...
4. Even I found REsponse Interface once again...
Still I am not getting where the error was ? Please guide me in detail in a right way in this issue.

Hello,
I already checked all those queues and context fields////
Based on my Observation I found
1) As I am unable to view the SOAP BODY I increased the RUN TIME Trace Level to 3 and LOG_VAlue to 3
2) ANother most Important that I found later doing these settings are....
    I found Receiver Pay LOAD and I copied that entire pay load and pasted it in
    REceiver Message Mapping> Test Tab and Code->PASTED...and compared all those parameters
    in the TEST TAB and DEFINITION TAB in Tree View whether all the mandatory receiver mapped
    elements are coming I mean passing from source or not...
OBSERVATION::
I found that for nearly 3 fields there is a difference when I compared on Tree View in DEFINITION TAB and also parallely in the TEST TAB Tree View which I got by copied from MONI,,,,
see for example ::
CENTRE <----
> DISCHARGE DATE..
For going to CENTRE..here I found that in DEfiniition TAB...
Control Act Event-->Subject->document-->Component>Structured body> component> Section>Component>PatientCareProvisionEvent->EffectiveTime-->CENTRE
But immediately I have gone to TEST TAB and TREE VIEW and I found that respective field CENTRE is posting I mean passing any value or parameter to Discharged Date or not...
But I found that...
Control Act Event-->Subject->document-->Component>Structured body> component> Section>Component-->_PatientCareProvisionEvent_
This Implies that Effective Time and Centre are missing in the XML and I mean no values are passing to receiver right..
In PI XSD 's it is there but in I think after Compiling REQUEST MAPPING and while in returning to RESPONSE MAPPING I mean whenever the Response is posting to SOAP WEBSERVICE it is unable to found those target elements and I think due to this...
Am I Correct ?
If that is the case...Let me know where the issue is whether in the data present in the WEBSERVICE created on target side or in PI Side..any issue...

Runtime exception for other than programming error.

In a conversation the question arose whether it could be a case of throwing a runtime exception for anything other than a bug. The tutorial on oracle site says "These Usually Indicate programming bugs" leading to think that can be used in situations in which there is no bug.
Anyone have a practical example of a runtime exception when there is no bug?
Thanks.

Ok. But. Do you think that in these cases the use of a runtime exception could be considered a bad practice?That's actually a matter of some debate.
On the one hand, Java has defined two major kinds of exceptions since the very beginning (unchecked exceptions, which are RuntimeException, Error, and their descendants; and checked exceptions which are everything else). The intended use of those was that checked exceptions should be for things that can normally go wrong in the execution of a program, even without a bug or without a major internal JVM error, such as a failed attempt to persist something or a network connection dropping--stuff that a programmer might normally be expected to deal with; while unchecked exceptions were created for things that a programmer would not normally handle in his code (except possibly at major architectural boundaries), like buggy code or an internal JVM failure.
With the rule about having to catch or declare checked exceptions, but not unchecked ones, that makes it easy for programmers so say, "Okay, I know exactly what can go wrong here that I might be expected to handle and I can therefore choose what to do with it; there will be no surprises. But I don't have to deal with problems that are outside my normal responsibility, like somebody passing me a null when they shouldn't have." It gives a programmer a nice bit of control, and the ability to know he hasn't missed something, kind of like the type safety provided by a strongly typed language.
At least that's the theory.
In practice, most checked exceptions either just get bubbled up to the next layer (via a throws clause), or caught wrapped in a fairly generic layer-appropriate exception and rethrown. There's not a whole lot of use made of what checked exceptions provide, and there's a lot of ugly boilerplate code that doesn't do anything useful for the app but is just there to satisfy the compiler.
So, some people think that checked exceptions are useless, or mostly useless, and favor unchecked exceptions in most or all cases. I believe that's part of the philosophy of Spring, but I'm not totally sure.
The idea is that since most of the time you can't do anything about exceptions that might be thrown to you, it's wasteful and pointless to have all that code to catch and rethrow. In this viewpoint, it would be better if, for example, not providing a throws clause at all meant that you could throw any exception. Any given code can still catch specific exceptions that it knows it can handle, but we don't have to write a bunch of code notating something that we're not really doing anything about.
Personally, I used to be totally in the checked exception camp. However, all the pointless boilerplate is wearing me down. I'm still not completely convinced though, and here's why: If I'm calling a method, I'd like to at least be able to see what might go wrong, so that I can decide how to deal with it. If all exceptions were unchecked, and the throws clause were optional, a conscientious developer could still provide it, and list the unchecked exceptions his method might throw to me, and/or he could document them in the javadoc comments. But a lot of developers won't do that, or even if they start to, as their method evolves, without the compiler to enforce it, they won't keep it up to date.
So there are advantages to both approaches. I personally would to know that the information will always be available to me, but for the small percentage of the time where I actually use it (like handle one specific exception one way and some other exception differently), I'm not sure if it's worth the overhead.

Constructor undefined runtime exception

Hi all,
This is the java prg which is throwing me runtime exception saying constructor undefined.Do anyone have idea of why its throwing I tried to find but am not..
Thanks in advance
package search;
public class SearchIntegratorException
extends RuntimeException
* @param p_message Exception message
public SearchIntegratorException(String p_message)
super(p_message);
* @param p_message Exception message
* @param p_cause Cause of the exception
public SearchIntegratorException(String p_message, Throwable p_cause)
super(p_message, p_cause);
* @param p_cause Cause of the exception
public SearchIntegratorException(Throwable p_cause)
super(p_cause);
} // end class

What's probably happening here is, you are compiling using javac 1.4, and running the code using java 1.3. If you notice, RuntimeException in 1.3 doesn't provide a constructor which takes Throwable as an argument. So when the class loads and you call your constructor that takes Throwable and call super(throwable), you get an exception that no such constuctor exists. But it compiles just fine, because java 1.4 RuntimeException has the appropriate constructor

Runtime exceptions from listeners

          When a servlet context listener throws a runtime exception, does the container
          catch it? It seems that
          the container just ignores the exception and tries to go on with life as usual.
          It does not even log the
          exception trace in the server log. Out of desperation, I finally put my entire
          contextInitialized() method
          in a try-block, and created a catch-block for RuntimeException which prints the
          exception stack-trace to
          the console.

          It seems that I'm not the only one bothered by this behavior
          (which is unspecified in the Servlet 2.3 spec).
