Paging Algorithm

Paging Algorithm

int topage = maxRecords * currentPage;
int offset = topage - (maxRecords);

Struts - Formating Text, Date or Number

Formating Pattern

format.time = {0,time}
format.number = {0,number,#0.0##}
format.percent = {0,number,##0.00'%'}
format.money = {0,number,\u00A4##0.00}

Formatting a number

<s:property value="getText('{0,number,#,##0.00}',{product.price})" />

JAVA - Reading file relatively

This will all getting the base path of you application to know how/where to read the file

Eclipse

Java Application

---

* File function

File fXmlFile = new File("test.xml");

The will look on the PROJECT_DIR path.

/YOUR/PROJECT_DIR/test.xml

* FileInputStream

FileInputStream is = new FileInputStream("test.cfg.xml");

The will look on the ECLIPSE path.

/YOUR/ECLIPSE_DIR/test.cfg.xml

* Loader context

ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
classLoader.getResource(".").getPath()

This will return: PROJECT_DIRt/build/classes/

Web Application(Running in Tomcat)

---

* Loader context

ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
classLoader.getResource(".").getPath()

This will return the path TOMCAT_DIR/lib/

* File function

File fXmlFile = new File("test.xml");

The will look on the ECLIPSE_DIR path.

/YOUR/ECLIPSE_DIR/test.xml

Deployed

---

* Java Application

* Web Application(Running in Tomcat)

* Loader context
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
classLoader.getResource(".").getPath()
This will return the path TOMCAT_DIR/lib/

* File function
File fXmlFile = new File("test.xml");
The will look on the TOMCAT_DIR path.

/TOMCAT_DIR/test.xml
