different type convert

1.CString to Char *

char* strTo= (char*)malloc(SIZE);
CString strFrom;

// wide char string to multibyte string
wcstombs(strTo,strFrom,SIZE);

// don't for get to free char after you finish
free(strTo);

2 char * to CString

char* strFrom;
CString strTo;

//construct a CString from char*
strTo = strFrom;

3 BSTR to CString

CString strTo;
BSTR strFrom;

// initialize the BSTR string
strFrom = SysAllocString(L"some string");

strTo.SetSysString ( &strFrom );
 
// free the BSTR string
SysFreeString ( strFrom );

4 CString to BSTR

// initiaslize the CString
CString strFrom = "some string";
BSTR strTo  = NULL;

strTo   = strFrom.AllocSysString();

// free the BSTR
SysFreeString ( strTo );

5 TCHAR * to char*

char* strTo = (char *)malloc( SIZE );;
TCHAR* strFrom;

// I got this from MSDN
for(int i = 0; i < _tcslen(strFrom); i++)
   strTo[i] = (CHAR) strFrom[i];

// another way to do this
wcstombs(strTo,strFrom, SIZE);

// don't for get to free char after you finish
free(strTo);

6. char * to TCHAR*

char* strFrom = (char *)malloc( SIZE );;
TCHAR* strTo;

// I got this from MSDN
for(int i = 0; i < strlen(strFrom); i++)
   strTo[i] = (TCHAR) strFrom[i];

// another way to do this
mbstowcs(strTo,strFrom, SIZE);

// don't for get to free char after you finish
free(strTo);

8.wstring to int

// initialize the basic_string
wstring strFrom=L"some string";
int nTo;

// pass the ponter c_str() a class constructer if it accepts this type
swscanf(strFrom.c_str(),L"%i",&nTo);

9 wstring to CString

CString strTo;

// initialize the wstring
wstring strFrom = L"some string";

// pass the pointer c_str() to the Cstring variable
strTo = strFrom.c_str();

10 char to num

char* strInt_From = "1234";
char* strFloat_From = "12.34";

int i = atoi(strInt_From );
float f = atof(strFloat_From);
 
11 char to wchar
char string[150] = "How are you?";
TCHAR wstring[150];

MultiByteToWideChar(CP_ACP, 0, string, -1, wstring, 150);

Channel_HTTP:C:\axis-c-1.6b-Win32-trace-bin\bin\HTTPChannel.dll

Channel_HTTP_SSL:C:\axis-c-1.6b-Win32-trace-bin\bin\HTTPSSLChannel.dll

Unfortunately, I modified a lot of axis’ code to let my rule service works, if you are familiar with c++ language, you can debug and find some codes need to change. Maybe with new release version, they will fix some bugs and add new functions.

1. Create java client stub codes

java -Djava.ext.dirs=c:\axis-c-1.6b-Win32-trace-bin\lib\axisjava -cp C:\axis-c-1.6b-Win32-trace-bin\lib\axis\wsdl4j.jar org.apache.axis.wsdl.WSDL2Java rule.wsdl

After this command was executed, some java class files should be generated. And you can write one class for testing. Just few lines.

RuleBeanSetInterfaceServiceLocator locator = new RuleBeanSetInterfaceServiceLocator();

DefaultNamespace.RuleBean bean = new DefaultNamespace.RuleBean();

DefaultNamespace.Param param = new DefaultNamespace.Param();

param.setName("nametest1");

param.setType("typetest1");

DefaultNamespace.Param param1 = new DefaultNamespace.Param();

param1.setName("nametest2");

param1.setType("typetest2");

DefaultNamespace.Param params[] = new DefaultNamespace.Param[2];

params[0] = param;

params[1] = param1;

bean.setParams(params);

bean.setRuleID("ruleIDtest".getBytes());

bean.setEventType("eventType".getBytes());

bean.setInputChanel("inputChanel".getBytes());

bean.setTemp("temptest");

locator.getrule().addRule(bean);

If you want to have a look the content of request message, just to add one line.

System.out.println(locator.getCall().getMessageContext().getRequestMessage().getSOAPPartAsString());

And you also can print response message.

2. Run and get resultYou can just run SimpleAxisServer and then run java client, you will see the method in server side should be called and executed successfully.

Axis(4)

1. Create c++ server codes

java -Djava.ext.dirs=c:\axis-c-1.6b-Win32-trace-bin\lib\axisjava -cp C:\axis-c-1.6b-Win32-trace-bin\lib\axis\wsdl2ws.jar org.apache.axis.wsdl.wsdl2ws.WSDL2Ws rule.wsdl -lc++ -sserver

After this command was executed, you will get some c++ files. You can create new dll project and add those files to compile. After compile, if you are luck with no errors , you will get a dll file.

2. Configure in Axis server

I am using independent server without application server. That is , SimpleAxisServer. For run this, you need configure two files.

One is server.wsdd, like

<?xml version="1.0" encoding="UTF-8"?>

<deployment name="defaultClientConfig"

xmlns="http://xml.apache.org/axis/wsdd/"

xmlns:java="http://xml.apache.org/axis/wsdd/providers/java"

xmlns:handler="http://xml.apache.org/axis/wsdd/providers/handler">

<parameter name="enableNamespacePrefixOptimization"

value="true" />

</handler>

</requestFlow>

</globalConfiguration>

<!--

</handler>

</requestFlow>

</handler>

</responseFlow>

-->

</service>

</service>

<!--

-->

</responseFlow>

</transport>

</deployment>

You will noticed that a service’s name is rule, that is what we want to test.

I think this is a bug or deficient function, I have to modify this file by hand, after I modified, the file likes like:

Axis webservice, java client call c++ server (1)

I want to use webservice as an communication platform from java to c++. No interesting with easy stuff , I want to pass in a java bean to c++ server side.

1. Write java interface first.

public class Param{

public String name;

public String type;

}

public class RuleBean {

public byte[] ruleID;

public byte[] eventType;

public List<Param> params;

public byte[] inputChanel;

public String temp;

}

public interface RuleBeanSetInterface {

public int addRule(RuleBean bean);

}

Why I am using public variable directly not using set/get as common java bean, because if declaration of variable is private will cause generated c++ class without any variable. Like

Class A

{

}
