I m calling an DLL (written in VC) in java but there is DLL function which uses hWnd as parameter But Java does not support that type. So is there any way to use hwnd in Java? or Some body tell me how to make such complex data type in Java?

HWND is simply an (unsigned) integer or void pointer. In Delphi at is used as a Longword which is an unsigned integer. If you simply use it to pass it on or store it, a normal Java integer should ...more

I want do call with JNI a C-DLL from a Servlet, but I got a java.lang.UnsatisfiedLinkError. As standalone-programm with an application it works perfect. When I analyse System-Calls, I found out, that the DLLs would be called, but the Wrapper-DLL would be closed, before the C-DLL are opened!!!

I am writing an jni application in which i use java objects and these objects are created at run time,i don't know the identifiers in it. how can i access them from the native method?

Assuming you create these objects from within your Java code, you'll have to get references to them in the same way you would do from within Java, ie. a variable referencing the object. Or, if you...more

It appears that the JNI routine "FindClass()" is incapable of finding those classes that inherit from another. Is this true? If not, why would "FindClass()" return success on some classes and not others within the same directory?

Make sure that you are using the fully qualified name for the class. For example, if you have a class named SomeClass in the package org.somepackage then make sure you are looking for org.somepac...more

Not exactly what you asked for, but there is an artile in javaworld that describes how to do custom windows, eg. round windows; http://javaworld.com/javaworld/javatips/jw-javatip86_p.html You ca...more

How can I access variables of the windows registry from my Java component residing on a weblogic server?

Use the trustice jnireg library. More information is at http://www.trustice.com/java/jnireg/.

i am working on a JExplorer using swing. When i click a particular file, the appropriate application should be opened. For example, for filename.doc windows word application should be opened. This seems possible,if i access windows registry. please let me know whether any Java API is available for this or have i to go for JNI.

You will need a jni library, there is no standard java interface. There is a library called jnireg available at http://www.trustice.com/java/jnireg/ that does this. Using this library, you can s...more
