Calling Java from Delphi

Question

Can ActiveX bridge used for calling Java from Delphi?

Answer 1

Also trying to solve this problem, after creating the bean i packaged/registered it successfully, (tested the bean using beanbox, works perfectly) then tried calling it via createoleobject in delphi 7
(*Code Snip *)
Var
v : variant;
begin
try
v := createoleobject(Edit1.text); // my class name ie WorldPort.Bean (also tried WorldPort.Bean.1
except on e:exception do
showmessage(e.Message)
end;
end;
(*Code Snip*)
After this simple code failed i started backtracking , eventually after getting "Access Violation...etc in axbridge.dll" all the time. tried delphi "import activex control" got the same access violation.
Decided to test the example from http://java.sun.com/j2se/1.4.2/docs/guide/beans/axbridge/developerguide/examples.html........ they both crashed on execution (calc.exe and boundprop.exe).
After this failed I tested these example classes on another machine, both crashed again.....
Also tried this experiment in VC++ , after adding the class to the Toolbox , i try to drop it onto a form, once again access violation.**PS**
('You will need VC++ and the Microsoft SDK to build the dll, download c++beta for free from microsoft site it you need it')** and a simple cmd file todo the job would look something like this:
echo - ** Build Java ActiveX Bridge **
echo Make sure these folders exist in jre--> axbridge\lib and axbridge\bin
cd\SDK\jre\axbridge\bin
set path=%path%;C:\MSDN\Bin;C:\VisualC++\lib
echo path
javac WorldPort.java
jar cmf Manifest.txt WorldPort.jar WorldPort.class
"C:\SDK\bin\packager.exe" -clsid {162193C4-AD5C-4A06-9F88-A737AE9B43AD} -out "C:\SDK\jre\axbridge\bin" WorldPort.jar WorldPort-reg
*** After running this cmd you will find the dll in bin folder and the jar in lib folder..***
Must Read:http://java.sun.com/j2se/1.4.2/docs/guide/beans/axbridge/developerguide/index.html
Hope some of this helps , if you have successfully created / installed/ used a "JavaActiveX" in Delphi , i would really like to try replicate it on my machine..
