Hi,

I am trying to implement ajax functionality in our web application which is based on struts 1.1.

I know how ajax works but not sure about the same in struts. I have below queries, could you please provide your inputs?

My requirement : Need to populate drop down values through ajax whenever user changes state and country on same page.

If I fire a action class via ajax, how should I write struts-config.xml? because on success there will be no forward page and do I need to include "ActionForward(mapping.findForward("success"))" in action class?

Please let me know the answers.

Thanks

Exception:

java.net.MalformedURLException: unknown protocol: c
at java.net.URL.<init>(Unknown Source)
at java.net.URL.<init>(Unknown Source)
at java.net.URL.<init>(Unknown Source)


souce code to initialize log4j under start of the java main method:

URL configURL_Log4j_File;
try {
configURL_Log4j_File = new URL(ExposureConstants.getLog4jConfigPath());
System.out.println(configURL_Log4j_File);
PropertyConfigurator.configure(configURL_Log4j_File);

} catch (MalformedURLException e2) {
// TODO Auto-generated catch block
e2.printStackTrace();
}


ExposureConstants.java :

public final static String APP_CONFIG_FILES_PATH = System.getProperty("user.dir");
public static String LOG4J_FILE_PATH = "";
public static String getLog4jConfigPath()
{
if(APP_CONFIG_FILES_PATH.contains("workspace"))
{
LOG4J_FILE_PATH = "C:\\CPCRM_PROJECT\\workspace\\cpcrm_reort\\log4j_Exposures.properties";

Hi,

We have a simple java application (no framework) which is deployed as EAR on weblogic. I have created the MSSQL datasource in weblogic for the access.

Now the requirement is to use oracle DB instead of MSSQL. I am able deploy the oracle connection in weblogic and tested successfully. But through Java side I am not sure what are the steps I need to make changes so that I can connect to oracle database.

I have class called DAOFactory which basically connects MSSQL as shown below:

private static String Application_POOL_NAME = "weblogic.jdbc.jts.ApplicationPool"; //JNDI


Do I need to change the above corresponding to oracle jndi name? Do I need to include any jars with respect to above operation?

Please provide me the guidelines so that I can follow it.

Thanks in advance

Hi All,

I am trying to deploy my application as package explode (not creating EAR/WAR files), while deploying I am getting JSP comilation erros as below:

Substituted for the exception weblogic.servlet.jsp.CompilationException which lacks a String contructor, original message - ExternalId.jsp:641:24: This tag is not recognized. <logic:present name="ExternalIdForm" property="institution"> ^-----------^ ExternalId.jsp:641:24: This tag is not recognized. <logic:present name="ExternalIdForm" property="institution"> ^-----------^ ExternalId.jsp:691:17: This tag is not recognized. <logic:iterate name="externalIdForm" property="externalIdList" indexId="ctr" id="voId" type="com.capitalone.crm.cpcrm.data.vo.ExternalIdBO"> ^-----------^ ExternalId.jsp:691:17: This tag is not recognized. <logic:iterate name="externalIdForm" property="externalIdList" indexId="ctr" id="voId" type="com.capitalone.crm.cpcrm.data.vo.ExternalIdBO"> ^-----------^ BaselLoad.jsp:581:7: This tag is not recognized.

Could you please tell me why JSP compilation is failing? I have all the necessary tag libraries under WEB-INF and referred in web.xml.

Hi All,

I am trying to instantiate inner class in java 5.0.11, but getting the below exception:

java.lang.NoClassDefFoundError: com/test/security/websso/sp/MobileRequestWrapper$MobileWrapperHttpServletRequest
com.test.security.websso.sp.MobileRequestWrapper.doFilter(MobileRequestWrapper.java:33)

The same works fine in Java 6.

Here is my code:


import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpServletRequestWrapper;
import org.apache.commons.lang.StringUtils;


public class MobileRequestWrapper implements Filter {



/** {@inheritDoc} */
public void init(FilterConfig filterConfig) throws ServletException {

}

/** {@inheritDoc} */
public void doFilter(ServletRequest servletRequest,
ServletResponse servletResponse, FilterChain filterChain)
throws IOException, ServletException {
String output = com.thl.gsk.DeviceDetectionUtil.processRequest((HttpServletRequest)servletRequest,(HttpServletResponse)servletResponse);
if(StringUtils.isNotBlank(output) && "mobile".equalsIgnoreCase(output))
{
System.out.println("----------------> in do filter of new class start");
HttpServletRequest wrappedRequest = new MobileWrapperHttpServletRequest(
(HttpServletRequest) servletRequest);
filterChain.doFilter(wrappedRequest, servletResponse);
}
else
{
filterChain.doFilter(servletRequest, servletResponse);
}


}

public void destroy() {
}


private static class MobileWrapperHttpServletRequest extends
HttpServletRequestWrapper {

public MobileWrapperHttpServletRequest(HttpServletRequest request) {
super(request);
}


@Override
public String getParameter(String name) {

System.out.println("----------------> in do filter of new class get parameter");
String originalValue = super.getParameter("cmd");
if (originalValue == null) {
return null;
} else {
String newVal = fixup(originalValue);
System.out.println("newVal in the brand new servlet ------------------------>"+newVal);
return fixup(originalValue);
}
}
private String fixup(String value) {
String newValue = null;
if("Home".equalsIgnoreCase(value)){
newValue = "MProductsByName";
}
return newValue;
}

Hi,

Can you please let me know how to save and bind the multiple values for a single field? For example, i have a form with field 'Interested in' and user can select more than one values, in this scenario how do i save the values and how to bind again to the view? what is the best design for this? I am using struts 2.

Similar scenario is like user will select multiple select boxes and i have to persist them and again i have to show the selected boxes in view..


Thanks

OK,

Then can you please tell me which method will invoke if i have only doPost method in servlet and did not mention any method type in the form submission?

No it is not. GET and POST should do different things. It's very short-sighted and a violation of the HTTP contract to just have them to the same thing.
