Hi ,

I am using the following Log4j properties for 2 applications.
The first 'RF' is rootCategory and 'ASW' is rootLogger

I want RF to log into test-log.txt
And ASW to admin-log.txt

But it is logging both in admin-log.txt.

#### Use two appenders, one to log to console, another to log to a file

log4j.rootCategory=info, stdout, RF
log4j.rootLogger= info, stdout, ASW

#### First appender writes to console
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

# Pattern to output the caller's file name and line number.

log4j.appender.stdout.layout.ConversionPattern=[%d{ISO8601}]%5p%6.6r[%t]%x(%F:%L) - %m%n


#### Second appender writes to a file
log4j.appender.RF=org.apache.log4j.DailyRollingFileAppender
log4j.appender.RF.DatePattern='.'yyyy-MM-dd

log4j.appender.RF.File=C:/jrpapp1/wrk/log/weblog/test/test-log.txt
log4j.appender.RF.layout=org.apache.log4j.PatternLayout
log4j.appender.RF.layout.ConversionPattern=[%d{ISO8601}]%5p%6.6r[%t]%x(%F:%L) - %m%n

#### Third appender writes to a file
log4j.appender.ASW=org.apache.log4j.DailyRollingFileAppender
log4j.appender.ASW.DatePattern='.'yyyy-MM-dd

log4j.appender.ASW.File=C:/jrpapp1/wrk/log/weblog/admin/admin-log.txt
log4j.appender.ASW.layout=org.apache.log4j.PatternLayout
log4j.appender.ASW.layout.ConversionPattern=[%d{ISO8601}]%5p%6.6r[%t]%x(%F:%L) - %m%n

I am trying to test it the following test program

import org.apache.log4j.Category;
import org.apache.log4j.Logger;
import org.apache.log4j.Priority;

public class TestLog4j {

private static Logger log = Logger.getLogger(TestLog4j.class.getName());
private static Category cat = Category.getInstance(TestLog4j.class.getName());



public void testLog(){

log.info("Just testing ASW INFO");
cat.info("Just testing RF INFO");

}

public static void main(String[] args) {

TestLog4j tLog = new TestLog4j();
tLog.testLog();

}

}

Thanks,
Boon

Hi

Could please explain Transaction token in Struts

Thanks,

Boon

Hi can anybody help me out.

thanks

Hi,

With the code given above I was able to use XSL. Now I get the output same as the jsp.

My doubt is:

I have a jsp file that generates the xml file with xsl file./

Before that,I need to parse the dynamic jsp file that fetches record from the database.

If i use DOM ,how should I pass the value for the xml file like

Document doc =
domparser.getDocument("c:/stocks/stocks.xml");
traverseTree(doc, out);

In the above example stocks.xml is a dynamic file which is not stored in any location.

The task i want to do is to convert a jsp to PDF using FOP.

I am able to print the jsp file in the form of xml .
The problem is how to parse it dynamically.

It would be helpful if anybody sends me the code.

Thanks
Boon

Hi ,
Thanks.I am not able to figure out.

I generated a jsp .(A table with 4 columns and 5 data)

I provided a link n it. PDF Version.

I also generated the xml document in the jsp page.
I mean the xml format is in .jsp file and not .xml file.
I try to use the xsl on the generated xml. I cant print the data rather it just prints the table header .

Please help me out.
I am first trying with simple xsl.Later I can change to xsl:fo.
This is my jsp that generate xml format.

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="clientstyle.xsl"?>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>


<%
int i=1;
%>
<TeamReport>
<Files>
<logic:iterate id="uploadfile" name="upfiles">
<download>
<sno>
<%= i++%>
</sno>
<filename>
<bean:write name="uploadfile" property="UPF_filename_mod1" />
</filename>
<filedate>
<bean:write name="uploadfile" property="UPF_filedate" />
</filedate>
<filepage>
<bean:write name="uploadfile" property="UPF_filepage" />
</filepage>
</download>
</logic:iterate>
</Files>
</TeamReport>

If I remove the highlighted line,it generates xml document.
The xsl is as follows.


<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.1" xmlns:xsl="http://www/w3.org/1999/XSL/Transform">
<xsl:template match="/">

Hi sahil,

I also have the same task.This is something like.

I fetch the list of values from the database.for each record it has a checkbox column.

Depending on a particular logic, I should check the checkbox . Later the user can check/ uncheck it while submitting.

Can you please be clear with the codes.
Thanks,
Bhuvana

I tried to solve. Instead of given the relative path I gave the full path name of the directory:

"D:/Tomcat/../../Client_UpFiles"+fileName;

It worked though.


I have another issue.

How do I download those files from a jsp.
How do i do the mapping.

Thanks,
Boon

hi ,
Thanks for the response. Based on the example,I configured this way. The problem is the out put on the Tomcat consile says the file is uploaded in the path . But the file isnt seen anywhere.

Pl. see the code snippet.
public ActionForward execute(ActionMapping actionMapping,ActionForm actionForm,
HttpServletRequest request,
HttpServletResponse response) throws IOException,ServletException
{

HttpSession session = request.getSession();

String insucode = "FMS";
String target= null;
String data= null;

System.out.println("Hello");

UploadFile theFile = (UploadFile) actionForm;

//retrieve the text data
String desc = theFile.getUPF_filedesc();


//retrieve the file representation
FormFile file = theFile.getUPF_fname();

//retrieve the file name
String fileName= file.getFileName();

//retrieve the content type
//String contentType = file.getContentType();


//retrieve the file size
// String size = (file.getFileSize() + " bytes");
System.out.println("Hello1");

String filepath = "/Client_UpFiles/";
System.out.println(filepath);

try {

System.out.println("Hello2");
//retrieve the file data
ByteArrayOutputStream baos = new ByteArrayOutputStream();
InputStream stream = file.getInputStream();

System.out.println("Hello3");
//write the file to the file specified
OutputStream bos = new FileOutputStream(filepath);
int bytesRead = 0;
byte[] buffer = new byte[8192];
while ((bytesRead = stream.read(buffer, 0, 8192)) != -1) {
bos.write(buffer, 0, bytesRead);
}
bos.close();
data = "The file " +file +" has been written to \"" + filepath + "\"";

//close the stream
stream.close();

}
catch (FileNotFoundException fnfe)
{
System.out.println(fnfe);
System.out.println("fnfe");
return null;

}
catch (IOException ioe)
{
System.out.println(ioe);
System.out.println("ioe");
return null;
}

System.out.println(data);

target = new String("success");
}



struts-config.xml
====================
<controller

maxFileSize="200K"
tempDir="/Client_UpFiles/">
</controller>

Pl help me out.
