can't find out why the digester doesnt find method in class
Hi there.
I'm using the struts digester to load some configuration parameters from an
xml file.
The digester source is:
Digester dig = new Digester();
dig.push(this);
dig.setValidating(false);
// log file configuration
dig.addObjectCreate("mls-config/logconfigfile",
"net.morkeleb.mls.type.ConfigParam");
dig.addSetProperties("mls-config/logconfigfile");
dig.addSetNext("mls-config/logconfigfile", "setLogConfigFile");
// create database config data
dig.addObjectCreate("mls-config/database",
"net.morkeleb.mls.type.DatabaseConfig");
//dig.addSetProperties("mls-config/database"); i guess i dont need this
here, but makes no change to exception
dig.addCallMethod("mls-config/database/driver", "setDriver", 0);
dig.addCallMethod("mls-config/database/url", "setURL", 0);
dig.addCallMethod("mls-config/database/user", "setUser", 0);
dig.addCallMethod("mls-config/database/password", "setPassword", 0);
dig.addCallMethod("mls-config/database/max-connections",
"setMaxConnections", 0);
dig.addCallMethod("mls-config/database/idle-timeout", "setIdleTimeout", 0);
dig.addCallMethod("mls-config/database/checkout-timeout",
"setCheckoutTimeout", 0);
dig.addCallMethod("mls-config/database/max-checkout", "setMaxCheckout", 0);
dig.addCallMethod("mls-config/database/monitoring-level",
"setMonitoringLevel", 0);
dig.addSetNext("mls-config/database", "configDatabase");
// let's start parsing
dig.parse(bis);
//close stream
bis.close();
The logconfigfile part goes well but the database part doesnt, with the
first method (setDriver) it tries
to call. Here's the class DatabaseConfig:
package net.morkeleb.mls.type;
import net.morkeleb.mls.tools.MLSLogger;
public class DatabaseConfig {
private String m_strDriver = "";
private String m_strUrl = "";
private String m_strUser = "";
private String m_strPassword = "";
private int m_iMaxConn = 0;
private int m_iIdleTimeout = 0;
private int m_iCheckoutTimeout = 0;
private int m_iMaxCheckout = 0;
private int m_iMonitoringLevel = 0;
public DatabaseConfig() {}
// database driver
public void setDriver(String strDriver) {
//MLSLogger.debug("setting Driver");
m_strDriver = strDriver;
}
public String getDriver() {
return m_strDriver;
}
// database url
public void setURL(String strUrl) {
//MLSLogger.debug("setting URL");
m_strUrl = strUrl;
}
public String getURL() {
return m_strUrl;
}
// databse user
public void setUser(String strUser) {
//MLSLogger.debug("setting User");
m_strUser = strUser;
}
public String getUser() {
return m_strUser;
}
// database password
public void setPassword(String strPassword) {
//MLSLogger.debug("setting Password");
m_strPassword = strPassword;
}
public String getPassword() {
return m_strPassword;
}
// database max connections
public void setMaxConnections(String strMaxCon) {
//MLSLogger.debug("setting MaxConnections");
try {
m_iMaxConn = (new Integer(strMaxCon)).intValue();
} catch (NumberFormatException exc) {
exc.printStackTrace();
}
}
public int getMaxConnections(){
return m_iMaxConn;
}
// database idle timeout
public void setIdleTimeout(String strIdleTimeout) {
//MLSLogger.debug("setting IdleTimeout");
try {
m_iIdleTimeout = (new Integer(strIdleTimeout)).intValue
();
} catch (NumberFormatException exc) {
exc.printStackTrace();
}
}
public int getIdleTimeout(){
return m_iIdleTimeout;
}
// database checkout timeout
public void setCheckoutTimeout(String strCheckoutTimeout) {
//MLSLogger.debug("setting CheckoutTimeout");
try {
m_iCheckoutTimeout = (new
Integer(strCheckoutTimeout)).intValue();
} catch (NumberFormatException exc) {
exc.printStackTrace();
}
}
public int getCheckoutTimeout(){
return m_iCheckoutTimeout;
}
// database max checkout
public void setMaxCheckout(String strMaxCheckout) {
//MLSLogger.debug("setting MaxCheckout");
try {
m_iMaxCheckout = (new Integer(strMaxCheckout)).intValue
();
} catch (NumberFormatException exc) {
exc.printStackTrace();
}
}
public int getMaxCheckout(){
return m_iMaxCheckout;
}
// database monitoring level
public void setMonitoringLevel(String strMonitoringLevel) {
//MLSLogger.debug("setting MonitoringLevel");
try {
m_iMonitoringLevel = (new
Integer(strMonitoringLevel)).intValue();
} catch (NumberFormatException exc) {
exc.printStackTrace();
}
}
public int getMonitoringLevel(){
return m_iMonitoringLevel;
}
}
and here's the method which it passes this class to:
// called by digester
public void configDatabase(DatabaseConfig db) {
JDBCConnectionManager.setDatabaseConfig(db.getDriver(), db.getURL(),
db.getUser(), db.getPassword(),
db.getMaxConnections(),
db.getIdleTimeout(), db.getCheckoutTimeout(),
db.getMaxCheckout(),
db.getMonitoringLevel());
}
and this is the xml file:
<?xml version="1.0" encoding="UTF-8"?>
<mls-config>
<logconfigfile value="/WEB-INF/log-config.xml"/>
<database>
<driver>oracle.jdbc.driver.OracleDriver</driver>
<url>dburl</url>
<user>dbuser</user>
<password>dbpassword</password>
<max-connections>10</max-connections>
<idle-timeout>300</idle-timeout>
<checkout-timeout>120</checkout-timeout>
<max-checkout>12</max-checkout>
<monitoring-level>300</monitoring-level>
</database>
</mls-config>
and here is what it throws:
MLS LogConfigFile: /usr/java/tomcat/webapps/mls/WEB-INF/log-config.xml
End event threw exception

This runs on a tomcat 3 server, but i've also tried on tomcat 4, where the
exception is slightly different,
but the problem is ofcourse the same.
Do you have an idea why this does not work?
I have copied some of the sources from another project where it works,
and looked through the digester documentation where i quite well follow
how it's ought to be done.
Thank you in advance,
Lukas
