Using Textbox strings in Java code

Hi,
I wonder if anyone can help me with a problem I'm
having with a JSP.
I've got several text boxes on my JSP which are static and would like to access their contents from within some dynamic Java code contained within the same JSP. I.e If I have a text box whose name is my_text I
would like to use my_text as a string within my Java code.
Does anyone know how to do this?
Thanks,
Peter

actually u can user java variable values in a html form/javacript but not vice versa.

Compile source string like java code

I need to calculate some user defined formulas in my application. I have this formula in string form (e.g. "operand1 * operand2 + operand3" ). I have gained operand values throught the reflection and pars this string throught the StringTokenizer. So I have parsed string with operand values and operators. Is it possible to compile this string like java code ?
Thanks for all hints

Compile to what - a class file?
Yes, it's possible if you don't mind using non-100% pure Java. You can compile them using the sun.tools.javac.Main class found from tools.jar in the lib directory of the jdk.
But from what you say it would be easier to use an existing expression evaluator. Take a look at JEP (jep.sourceforge.net) and BeanShell (www.google.com) before you make any decision.

Using jsp variable in java code

Hey guys,
I need some help hope you guys can help me.
I've declared a variable "error" in a jsp. how do I access this variable in the java code whice resides in the same jsp page.
I know I can use java variable in jsp code using
<%= sVariable %>
where sVariable was declared in the java code. but how do I access a jsp variable in java code??
Thanks very much in advance

Thanks for the reply.
This is what I want to do.
I've declared a variable "error" using <c:catch var="error">I want to check the value of this variable and suppose if it contains XYZ (error variable will have a long string so I just want to check if it contains a specific value) I want to do step1 and if the variable of error is not XYZ I want to do step 2
Problem is I dont know how to check if error contains the XYZ in jsp thats why I thought java code would help here.
Can you guys suggest a better way to solve my problem.
Thanks again

Converting String into Java code

Hi everyone,
I will describe the scenario I have. I have a GUI application. I want the user to write some Java code in a text box and plug that code during runtime. Is there a way in Java so that a string could be used as a Java code?
You help is really appreciated.
Thanks
RG

catch the string input
output string (code) to file
call javac on the file you made
that's it, you have a class, and you can run it/load it

Tools for extracting strings from java code for internationalization

For legacy code with lots and lots of strings what method is typically used to extract strings for internationalization?
Am I right in thinking you couldnt simply grep for strings, it could get pretty complitcated, especially with escape characters, escaped quotes etc.,
-SK

When dealing with legacy code, it is nice to have an application that queries you as it extracts the strings. You have a choice whether to accept the string as a localizable entity or not.
There are several tools that do this...including some IDEs like JBuilder. Although it isn't a fully supported or robust tool, Sun has a utility for extracting strings in Java source files:

Using getProperty in my Java code.

I am reading the attached XML file into my Java classes.
<Config>
<Properties>
     <entry key="rmi.remotecontrol.port">30</entry>
</Properties>
<AListener>
          <Subscriber></Subscriber>
          <Database>
               <URL>jdbc:oracle:thin:@0.0.0:1521:dev</URL>
          </Database>
</AListener>
</Config>
My Java code displays the correct output when I say:
System.out.println("The RMI Port name property: " + prop.getProperty("rmi.remotecontrol.port"));
Output : 30Now,if I want to get the URL address of the database,and when I use
System.out.println("The RMI Port name property: " + prop.getProperty("Database.URL"));
Output is null.How do I get the value of the URL using getProperty?
Thanks,

you're a complete idiot. seriously. three separate threads, days apart, each with the same mistake in, pointed out by me several times each thread, links to exactly the documentation you need, code actually pasted into the thread from the documentation, several patient explainations, and you still haven't bothered actually listening to me
other posters beware: check this fools posting history for an insight into how they repeatedly ignore advice on this problem before deciding whether it's worth your effort replying - it isn't. this clown simply ignores being told directly what is wrong here, and even ignores being given the exact fix. no point replying

I want to use £ in euro in java code

Hi,
I want to use £ as euro symbol in java code please help me as soon as possible.

It's not 100% clear what you are asking:
I want to use £ as euro symbol in java codeDo you mean you want to display a Euro symbol? If so, you use € (if your font supports it) but I suspect that is too easy you must mean something else. Can you ask the question again but rephrase to make it clearer what you want to do. Do you want to use the symbol in a particular Java component?

How to use odi variable in java code.

Hi,
I am trying to calculate check sum of a file and need to capture that in a odi variable...
I wrote code like this(selected technology as java bean shell)
<@
import java.io.*;
import java.util.zip.*;
public class checksum {
public static void main(String[] args) throws Exception {
FileInputStream fis = new FileInputStream(new File("c:/dummy.txt"));
CheckedInputStream cis = new CheckedInputStream(fis, new CRC32());
BufferedInputStream in = new BufferedInputStream(cis);
while (in.read() != -1) {
#checksum = cis.getChecksum().getValue();
}@>
But I am not able to get that value...
I tried in another way like this
<@
import java.io.*;
import java.util.zip.*;
public class checksum {
public static void main(String[] args) throws Exception {
long result;
FileInputStream fis = new FileInputStream(new File("c:/dummy.txt"));
CheckedInputStream cis = new CheckedInputStream(fis, new CRC32());
BufferedInputStream in = new BufferedInputStream(cis);
while (in.read() != -1) {
result= cis.getChecksum().getValue();
@>
In odi variable refreshing mode i selected schema as memory_engine and wrote
select '<@=result@>' from dual;
even this wont work for me :(
Anyone pls help me in this...
Thanks in advance
Pavan

Hi Phani,
Thanks for the reply. I resolved this. The mistake is I wrote java code in a class,in main function. I removed class and main function. Now I am able to capture value into Odi variable...
I modified code as
<@
import java.io.*;
import java.util.zip.*;
long result;
FileInputStream fis = new FileInputStream(new File("C:/dummy.txt"));
CheckedInputStream cis = new CheckedInputStream(fis, new CRC32());
BufferedInputStream in = new BufferedInputStream(cis);
while (in.read() != -1) {
result=cis.getChecksum().getValue();
@>
finally retrieving result value from dual
select '<@=result@> from dual

How to Use Exec function in Java Code

How to Use Exec method
I want to Execute command
net Start "some service"
using exec method of runtime class
or i use some other way if suggest

Assuming you have read http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Runtime.html#exec(java.lang.String) already, I can only suggest to be more specific in what your problems are. If you are after just some example code, then download ftp://ftp.ebi.ac.uk/pub/software/textmining/monq/monq.tar.gz and have a look at the source code of monq.stuff.Exec. It does all those things which are necessary to keep track of a Process after it was created with exec.

How to use the XULRunner with JAVA Code

Hi, all
I have a big problem about XULRunner. I can not find a nice solution on the internet. So I have to request you to give me some ideas.
We know the XULRunner is nice solution when we want to embed a browser into desktop program which is thunderbird, firefox and so on.
My questions are the following:
1. Can I execute a Java function accross the JAVASCript? We can execute javascript code in the JAVA, but I'm not sure I can do opposite it.
2. What is javaxpcom?
If you did program like this, please give me some ideas, thanks very much.

I marked this as "off-topic" since it's not a Firefox support question.
Another place for discussion related to XULRunner, besides the Mozilla community links at https://developer.mozilla.org/en-US/docs/Mozilla/Projects/XULRunner might be one of the [http://forums.mozillazine.org/ MozillaZine forums], such as the Mozilla Development forum:
*http://forums.mozillazine.org/viewforum.php?f=27
EDIT: I'm leaving this question open since it's about another Mozilla product and I'm escalating it to the Helpdesk in case anyone over there has a suggestion.
