i am using IKVM to convert a java jar file to a c# dll.
This jar file has several dependencies, which i referenced all via -r:reference.dll .
Still im getting the following warning and i dont know how to get rid of it:
IKVM.NET Compiler version 7.2.4630.5
Copyright (C) 2002-2012 Jeroen Frijters
http://www.ikvm.net/
warning IKVMC0111: Emitted java.lang.NoClassDefFoundError in "myproject.myclass.setFocus()V"
("org.eclipse.swt.widgets.Control")
The command i am converting the jarfile is:
ikvmc -target:library -debug -out:project.dll -r:org.eclipse.swt.win32.win32.x86_3.5.2.v3557f.dll -r:severalmoreherretofollow project.jar 2> project.log
The class "org.eclipse.swt.widgets.Control" is declared inside the "org.eclipse.swt.win32.win32.x86_3.5.2.v3557f.dll" which had no errors when compiling it with ikvm to a dll.
Thanks in advance
If you compile more as one jar file then it can be recommended to compile it in one step. See the wiki for more details. This prevent you from circulate dependencies.
I think you need to use a full qualified file name with the -r option.

Getting "Imported library 'ExcelLibrary' contains no keywords." warning message while running the script and ExcelLibrary keywords have not been recognized.
Any help to resolve this issue?
Specifying the path of ExcelLibrary explicitly in the POM xml resolved this issue.
<extraPathDirectory>C:\Python\Python36-32\Lib\site-packages\ExcelLibrary</extraPathDirectory>
Downloaded LWJGL 3.0 from lwjgl.org, which only had the lwjgl.jar file in the jar subdirectory. The native directory only has files like libglfw.so but no subdirectories at all (and certainly not native/windows).
Created a library LWJGL30 with the lwjgl.jar file.
Added it to my project's library. and to the Project Properties->Libraries->Compile and Run.
Set the JVM launch argument in Project Properties->Run to -Djava.library.path=C:\Users\Owner\Documents\lwjgl\native for the VM Options
Copied the HelloWorld example from the link
Then ran and I get this error:
Exception in thread "main" java.lang.NoClassDefFoundError: Could not

C:\Users\Owner\AppData\Local\NetBeans\Cache\8.1\executor-snippets\run.xml:53:
Java returned: 1 BUILD FAILED (total time: 7 seconds)
I have checked, double checked, triple checked as well as searching online for an answer as it should work but it does not. Any help would be appreciated.
This error occurs when LWJGL is unable to find the native files. Make sure java.library.path actually points to the directory with LWJGL's natives (which have extensions like .dll, .so and .dylib). Be careful with spaces in the path: You have to wrap the path in quotation marks or it won't work.
The issue was I was running the HelloWorld example using the Stable version of LWJGL 3.0. When I switched to the Latest version, everything worked as expected.
hi im creating a lift scala application
this is my problem
when i import net.liftweb.mapper._ package the compiler gives me error...
i tried to add lift-mapper_2.9.1-2.4-M4.jar jar file to build path ,but the error exists..!
the compiler shows..
bad symbolic reference. A signature in package.class refers to term db in package net.liftweb which is not available. It may be completely missing from
the current classpath, or the version on the classpath might be incompatible with the version used when compiling package.class.
Try to add the mapper via SBT or maven configuration?
Anyway, Scala-2.9.1 and Lift 2.4-M4 are very-very out of date. Better use something like that for a good start: https://github.com/lift/lift_25_sbt/
It works out of the box, and you'll only have to add 1 line to add the mapper support for it. (After that, all dependencies would be downloaded and added to the project automatically, by SBT.)
I'm having this exception with some stubs generateds by Axis2:
"The type org.apache.axiom.om.OMElement cannot be resolved. It is
indirectly referenced from required .class files"
I've been reading many posts, and trying to find a solution. What I've found so far is to add the apache tomcat 5.5 library to the build path. It removed the error in the java file, but then, when I to execute any java program inside the project, I got this error:
'Launching myApp' has encountered a problem Exception occurred
executing command line. Cannot run program "C:\Program
Files\Java\jdk1.5.0_22\bin\javaw.exe" (in directory
"D:\Digicel\workspace\Digicel\myClassSample"): CreateProcess error=87,
The parameter is incorrect
then if I remove the apache tomcat library from the build path, I can run the other java programs, but not the one mentioned initially.
Any thoughts about it?
Okay, I've found the cause of the problem with the help of a friend :)
The thing is that Eclipse is aware that one of my dependencies, depends of another library, and Eclipse is checking for it when it tries to build the code.
So, what I've done is try to check which jar file contains this library: " org.apache.axiom.om.OMElement".
I've googled it and found that it is "axiom-api-1.2.10.jar" and finally my file compiled with 0 errors.
He also explained to me that my original solution of adding the apache tomcat server library is adding all the jars that cames with apache tomcat (which is a big list), and probably there may have been a version conflict with my current list of added jars.
So, the fix was to find the appropriate jar and add it to the project.
This error can also occur when a indirect dependency has a corrupt jar file. This may be caused by problems at the public maven repository.
If this is the case removing the local maven repository to download fresh jar files will fix your problem:
rm -Rf ~/.m2/repository/{enter/path/to/broken/stuff}
Goto Maven >Update Maven project>checkmark the Force update >Then Run
..That error Will gone....
Im trying to put together a simple ant build file for compiling a scala project (scala 2.7.6)...
I have everything working correctly except that its bringing up the
"fatal error: class java.lang.Object not found." both the scalac and scala libs are all in the project folder, so Im refering to them relativelly to the project root.
Im hoping that someone could help with which command line scalac option I can use to point the compiler towards the java core lib (if thats what it needs). Im hoping not to use any environemnt variables, and instead have the needed java libs in my project root folder...
that way I can have everything needed to compile movable with the project, and not need any setup for others to be able to compile
thank you
Scala 2.7.6 is a broken release.
Please upgrade to 2.7.7
Also, do you have javac on PATH and JAVA_HOME set?
