Hi,
this time i devolope an leightweight ajax server where the
java-serverside and the java-applet shares classes.
(i.e.)
incomming request to class: org.enexus.Tools -> rewrite class (invoke
agent)-> send class to applet -> applet call static Tools-method - >
agent serialize to XML -> agent XML to Server -> deserialize to
reflection call -> call method on server -> serialize result object to
XML -> send to applet -> agent deserialize xml to result object ->
Tools-method returns result object.
Now, when the applet requests for an server-side-class apperars my
server send a rewrited class.
The rewrite have to:
call an invoker-method on applet which becomes all the method
parameters, the full-qualified method-name and the method's result-object.
Everything works fine, but i down know how to plug the parameters into
the agents-method-parameters.
This code i have written:
for (int i = 0; i < classMethods.length; i++)
if (!classMethods[i].getName().equals("<init>") &&
classMethods[i].isPublic()) {
com.sun.org.apache.bcel.internal.classfile.Method m =
classMethods[i];
Type[] argumentTypes = classMethods[i].getArgumentTypes();
String[] namen = new String[argumentTypes.length];
for (int j = 0; j < namen.length; j++) {
namen[j] = "arg" + j;
}
InstructionList instructionList = new InstructionList();
Type returnType = classMethods[i].getReturnType();
MethodGen mg = new MethodGen(classMethods[i]
.getAccessFlags(), returnType,
argumentTypes, namen,
classMethods[i].getName(), c.getName(),
instructionList, cg.getConstantPool());
mg.setMaxStack(50);
InstructionFactory inf = new InstructionFactory(cg);
instructionList.append(inf.createNew(Type.OBJECT));
instructionList.append(inf.createInvoke(
"de.enexus.BCELConnector", "callFromApplet",
returnType,
argumentTypes, Constants.INVOKESTATIC));
// If there is a return value, return it
instructionList.append(inf.createReturn(returnType));
mg.setMaxStack();
mg.setMaxLocals();
cg.addMethod(mg.getMethod());
System.out.println(mg.getMethod());
}
byte[] bytes = cg.getJavaClass().getBytes();
String string = new String(bytes);
return string;
