Re: [Php-java-bridge-users] trouble finding methods

Hi,

You can use

 echo java_inspect ($javaObject);

to list the public methods.

It's a misunderstanding. Unlike other languages which have a meta object protocol the Java
language doesn't allow methods for classes (the so called "class methods" are only procedures
bound to that type, you can't override them).

No, it is a misunderstanding.  The procedure java("typeName") returns a type, while new
Java("typeName") returns an instance. The new JavaClass("typeName") is the low-level interface
used by the java() procedure.

Use 

  java("typeName")->staticProcedureName() 

to call Java procedures belonging to "typeName". Use 

  $obj = new Java("typeName");
  $obj->methodName()

to call methods.
