Update Records Into M.S Access/SQL Table Using Java Servlet Programming

Home	»	Java	»	Advance Java	»	Java Servlet	»	Update Reocords

The following are two Java Servlet Server side programs and one HTML Client Side. HTML Program will send client side information for find out a specific or selected data from M.S.Access/SQL table and Java Servlet (Server Side) program will display specific records from database. and second java servlet program will update records into M.S.Access Table. For this first of all you need to create a M.S.Access database or SQL... but in this example I'm using M.S.Access. Create one table in M.S Access as shown below:

Table Definitions:

Table Name	: [ICTCashBook.mdb]-Download
Primary Key	: VoucherNo
Foreign Key	: Nil

Column Definition:

Column Name	Data Type
ID	AutoNumber
Session	Text
Month	Text
DD	Number
MM	Number
YY	Number
VoucherNo	Number
Articles	Memo
FromWhichPurchsed	Memo
Amount	Number
Remarks	Memo

Table Description:

Column Name	Description
ID	Create AutoNumber for image id
Session	insert Session for ex. 2011-12
Month	insert month in text...
DD	insert date in numeric
MM	insert month in numeric
YY	insert year in numeric
VoucherNo	insert unique numeric no
Articles	insert text
FromWhichPurchsed	insert text
Amount	insert numeric value
Remarks	insert text/numeric value

After create table in M.S. Access database now you will create DSN.

and for Download Apache Tomcat 4.0 then Click Here

Now compile the above both code using javac compiler...

C:\jdk1.4\bin>javac UpdateIncomeExpenditure.java -classpath "C:/Program Files/Apache Tomcat 4.0/common/lib/servlet.jar"

C:\jdk1.4\bin>javac UpdateIncomeExpenditures.java -classpath "C:/Program Files/Apache Tomcat 4.0/common/lib/servlet.jar"

Now, copy "UpdateIncomeExpenditure.class" and "UpdateIncomeExpenditures.class" Files from c:/jdk1.4/bin/ and then paste it under below dir...

"C:/Program Files/Apache Tomcat 4.0/webapps/examples/WEB-INF/classes/"

or use below command

C:\jdk1.4\bin>copy UpdateIncomeExpenditure.class "C:/Program Files/Apache Tomcat 4.0/webapps/examples/WEB-INF/classes/"

C:\jdk1.4\bin>copy UpdateIncomeExpenditures.class "C:/Program Files/Apache Tomcat 4.0/webapps/examples/WEB-INF/classes/"

or you can use "*.class" for copy all classes...

C:\jdk1.4\bin>copy *.class "C:/Program Files/Apache Tomcat 4.0/webapps/examples/WEB-INF/classes/"

Now Open any web browser and type client side URL into address bar as below...
