Body
I have following three files: sab1.hpp: <pre><code>class CRectangle { int x, y; public: void set_values (int,int); void print(char **db); int area (); }; </code></pre> sab1.cpp: <pre><code>#include <iostream> #include "sab1.hpp" using namespace std; int CRectangle::area () { return (x*y); } void CRectangle::set_values (int a, int b) { x = a; y = b; } void CRectangle::print(char **db) { cout <<db[0]; } int main () { CRectangle rect; char *a[] = {"Hi", "bye" } ; rect.set_values (3,4); cout << "area: " << rect.area(); rect.print(&a[0]); return 0; } </code></pre> sab1.i : <pre><code>%module Rec %{ /* Includes the header in the wrapper code */ #include "sab1.hpp" %} class CRectangle { int x, y; public: void set_values (int,int); void print(char **db); int area (); }; </code></pre> I create various intermediary file using the following usual commands: 1) swig -c++ -java sab1.i 2) g++ -fpic -c sab1.cpp sab1_wrap.cxx -I /usr/lib/jvm/java-6-openjdk-i386/include/ -I /usr/lib/jvm/java-6-openjdk-i386/include/linux/ Then I create a shared library using this: g++ --shared sab1.o sab1_wrap.o -o libegs.so Then I create a following Java file for accessing the functions of the C++ class: <pre><code>public class Test { public static void main(String args[]) { System.loadLibrary("egs"); CRectangle a = new CRectangle(); a.set_values(4,5); System.out.println(a.area()); a.print("Hi"); } } </code></pre> When I compile the Java File (javac -classpath . Test.java ), I get the following error: <pre><code>Test.java:17: print(SWIGTYPE_p_p_char) in CRectangle cannot be applied to (java.lang.String) a.print("Hi"); ^ </code></pre> So, how can I make the Java code understand the char ** variable? I have tried creating typemaps in the SWIG interface file (sab1.i) but I'm not able to correctly figure it out. Thanks in advance for the help.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
