Welcome! All the best!

I hope to find the answers to some of the toughest Java multi threading questions.

Regards!

To the authors:

Which big company or community is already using Camel in theirs applications? Are there some use cases to tell us?

Thanks!

What do you think about the open-source SOA solutions by IONA (Apache with Progress Software)?

Like:

FUSE ESB - based on the Apache ServiceMix - JBI specification (JSR 208)

FUSE Message Broker - based on Apache ActiveMQ

FUSE Services Framework - based on Apache CXF. (plus: JAX-WS, JavaScript, REST, POJOs)

FUSE Mediation Router - based on Apache Camel

FUSE Integration Designer - based on Eclipse

Another question: does your book contain any of these solutions?

OSGi and Spring - These techniques / tools have something to do with the old META-INF and MANIFEST.MF?

In "Linux world, there were options before JavaFX? If not, this is good or bad?

I think AJAX will dominate de world (wide web).

Is there some information about JBoss Rich Faces mentioned in the book? This tool is making me so happy so I hope it get more new resources, even in server side (if possible).

Hi, everybody.

I want to repeat this code in my page for any page I have:

<h:commandLink action="#{cliente.selectNumberPage}" value="1">
<f:param name="jsfcrud.chosenPage" value="0"/>
</h:commandLink> 

For example, for a list with 3 pages, it would be:

<h:commandLink action="#{cliente.selectNumberPage}" value="1">
<f:param name="jsfcrud.chosenPage" value="1"/>
</h:commandLink> 
<h:commandLink action="#{cliente.selectNumberPage}" value="2">
<f:param name="jsfcrud.chosenPage" value="2"/>
</h:commandLink> 
<h:commandLink action="#{cliente.selectNumberPage}" value="3">
<f:param name="jsfcrud.chosenPage" value="3"/>
</h:commandLink> 

I've tried with "c:forEach", but JSF doesn't recognize the variable when it's "loading" the page.

Does everybody knows a way to do that in a good practice way?

Hi...

I'm sorry for "revive" this topic... but I'd like to know a example of using Jasper Reports and JSF in that way cited?

I'm having a lot of errors using "context.getExternalContext().dispatch(..." in a Managed Bean filter that call a report.

Best regards!

Hi.

I'm with the same doubt.

How implement the calling between step 1 and 2. By calling a servlet?

Thanks a lot for the tips! It will help me a lot besides clean my code!

The method HAS a body, I just didn't put it here this way in the example.

Hello!

I got what I wanted doing this:

regex = "(?m)void myMethod\\(\\)\r\n\\{\r\n\\}"
String newFileContent = fileContent.replaceAll(regex, "/*"+regex+"*/");

It replaces every method with coments... just what I wanted. I don't know if it is just right using regex this way... but is working, now...

Regards!!!

Hi... I'm using JSF h:commandLink and I want something that I think won't work this way.

I wanted to use f:param inside the h:commandLink to pass parameters by using a "rendered" property to the backing bean.

Here is the code:

h:commandLink rendered=UserMB.permission value="Menu Customers"
f:param name="functionalityParam" value="customerList"
h:commandLink

It seems the parameter is "loaded" in the Map only at Action time, and don't at "rendered processing" time.

Is it impossible to get what I want?

Best regards, saloon!

Hi, again.

I found a topic in this forum and I tested the code, but I think I don't know how to use some methods very well, like "replace all". Topic is: https://coderanch.com/t/411621/java/java/Pattern-matches-but-never-replaces

Using that code, when I look for "void myMethod(){}" works well, but if I change the text to multiple lines, it doesn't work.

"
void myMethod()
{
}
"

I'm posting the code that I tested.

import java.util.regex.*; import java.io.*; import java.nio.*; import java.ninio.*; import java.nio.channels.*; /*** * Strips out empty spaces and comments* * @author M Habibi */ public class Teste2 { public static void main(String args[]) throws Exception { String fileName = "c:/tmp.txt"; updateFileContent(fileName, "(?m)void myMethod\\(\\)\n\\{\\}","/**method erased**/"); [B]//THE SECRET SEEMS TO BE HERE! I used \n to find multiple lines[/B] } /** * updates the content of the file. By default, the * Pattern.MULTILINE is used. Also supports the * $d notation in the replacement string, per the * Matcher.replaceAll method * @param the String fileName is the name and file path * @param the String regex pattern to look for * @param the String replacement for the regex * @throws IOException if there is an IO error * * @return boolean true if the file was updated */ public static boolean updateFileContent(String fileName, String regex, String replacement) throws IOException { boolean retval = false; RandomAccessFile raf = new RandomAccessFile(fileName, "rwd"); FileChannel fc = raf.getChannel(); String fileContent = getFileContent(fc); //Activiate the MULTILINE flag for this regex regex = "(?m)" + regex; String newFileContent = fileContent.replaceAll(regex, replacement); //if nothing changed, then don't update the file if (!newFileContent.equals(fileContent)) { setFileContent(newFileContent, fc); retval = true; } //close up shop fc.close(); fc = null; raf = null; return retval; } /** * sets the content of a file. Completely * overwrites previous file content, and truncates * file to the length of the new content. * @param the <code>String</code> newContent * @param the <code>FileChannel</code> fc * @throws <code>IOException</code> * * @author M Habibi */ private static void setFileContent(String newContent, FileChannel fc) throws IOException { //write out the content to the file ByteBuffer bb = ByteBuffer.wrap(newContent.getBytes()); //truncate the size of the file, in case the //original file content was longer the new //content fc.truncate(newContent.length()); //start writing as position 0 fc.position(0); fc.write(bb); fc.close(); fc = null; } /** * extracts the content of a file * @param FileChannel fc the file to extract from * @throws IOException * * @return String representing the contents of the file */ private static String getFileContent(FileChannel fc) throws IOException { String retval = null; //read the contents of the FileChannel ByteBuffer bb = ByteBuffer.allocate((int) fc.size()); fc.read(bb); //save the contents as a string bb.flip(); retval = new String(bb.array()); bb = null; return retval; } }

Hello!

Does anyone knows how can I do a "search and replace" using REGEX, but I want to match several lines.

For example, I want to open a TXT file and find:

void myMethod() { }

and replace it for:

/* void myMethod() { } */

Like "put" a comment on it.

Thanks!
