I created a project inside the ofbiz/hot-deploy folder namely productionmgntSystem. Inside the folder ofbiz\hot-deploy\productionmgntSystem\webapp\productionmgntSystem I created a .ftl file namely app_details_1.ftl.The following is the code of this file

I want to upload a file to the server.The file is get from user <input type="file"..> tag in the app_details_1.ftl file & it is updated into the server by using the method testingService(HttpServletRequest request, HttpServletResponse response) in the class WebServices1. But the file is not uploaded.
I got the solution to my problem.I successfully upload the file into the server.This solution i get after the big fight with ofbiz.I made a little changes in my old coding.That is given below.
the following are the coding present in the "app_details_1.ftl"
<html>

window.location='<@ofbizUrl>logout1</@ofbizUrl>'

</body>
</html>
Here my main changes in the form action attribute.
The following are the coding snippet in "controller.xml"
...............
.............
<request-map uri="uploadAttachFile">
<security https="true" auth="true"/>
<!-- <event type="simple" invoke="createCommunicationContent" path="component://productionmgntSystem/script/org/ofbiz/productionmgntSystem/CommunicationEventEvents.xml"/> -->
<event type="java" path="org.ofbiz.productionmgntSystem.web_app_req.Uploading" invoke="uploadFile"/>
<response name="AttachementSuccess" type="view" value="AttachementSuccess"/>
<response name="AttachementException" type="view" value="AttachementException"/>
</request-map>
................
.....................
<view-map name="AttachmentError" type="ftl" page="file_attach_error.ftl"/>
<view-map name="AttachementException" type="ftl" page="file_attach_error.ftl"/>
<view-map name="AttachementSuccess" type="ftl" page="AttachementSuccess.ftl"/>

Here i should map a request "uploadAttachFile" to the event "uploadFile".That is this event call the method "uploadFile" inside the class "org.ofbiz.productionmgntSystem.web_app_req.Uploading".This class is defined by me.Actually file uplaod is there in ofbiz i just copy the coding & altered some changes for my application.
Inside the method "uploadFile" is i write the coding for uploading the file into server. I stored the class "org.ofbiz.productionmgntSystem.web_app_req.Uploading" in the following folder "ofbiz\hot-deploy\productionmgntSystem\src\org\ofbiz\productionmgntSystem\web_app_req". Here the "productionmgntSystem" is the my application name.
The following are coding present inside the class "org.ofbiz.productionmgntSystem.web_app_req.Uploading"
//UPLOADING A CONTENT TO THE SERVER

String file_name="";
try
{

}
catch (FileUploadException fup_ex)
{
System.out.println("\n\n\t****************************************\n\tException of FileUploadException \n\t");
fup_ex.printStackTrace();

return(result);
}
if(lst.size()==0) //There is no item in lst
{
System.out.println("\n\n\t****************************************\n\tLst count is 0 \n\t");

return(result);
}

return(result);
}
byte[] file_bytes=selected_file_item.get();
byte[] extract_bytes=new byte[file_bytes.length];
for(int l=0;l<file_bytes.length;l++)
extract_bytes[l]=file_bytes[l];

if(extract_bytes==null)
{
System.out.println("\n\n\t****************************************\n\tExtract bytes is null\n\t");

return(result);
}
/*
for(int k=0;k<extract_bytes.length;k++)
System.out.print((char)extract_bytes[k]);
*/
//String target_file_name="/hot-deploy/productionmgntSystem"
//Creation & writing to the file in server - Start
try
{
FileOutputStream fout=new FileOutputStream(file_name);
System.out.println("\n\n\t****************************************\n\tAfter creating outputstream");
fout.flush();
fout.write(extract_bytes);
fout.flush();
fout.close();
}
catch(IOException ioe_ex)
{
System.out.println("\n\n\t****************************************\n\tIOException occured on file writing");
ioe_ex.printStackTrace();
result="AttachementException";
return(result);
}
//Creation & writing to the file in server - End
System.out.println("\n\n\t****************************************\n\tuploadFile(HttpServletRequest request,HttpServletResponse response) - end\n\t");
return("AttachementSuccess");
//Uploading the file content - End
}
}
Now in my application im able to upload the file into the server.
