I have installed the latest JEE 5 SDK on Win XP Home. I have the following variable set as follows,
CLASSPATH = .;C:\Program Files\Java\j2re1.4.2_03\lib\ext\QTJava.zip
PATH = C:\Sun\AppServer\jdk\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\Microsoft SQL Server\80\Tools\BINN;C:\Program Files\QuickTime\QTSystem;C:\Sun\AppServer\lib\ant\bin
ANT_HOME = C:\Sun\AppServer\lib\ant
I have spent hours scratching my head but don?t have a clue. I was wondering if you have any idea as why I might be getting these errors.
Thank you for your time.

Hello, did you read the answers?
You have to put j2ee.jar or servlet-api.jar in your classpath. Those JAR files are included in the Java EE package somewhere. Remove the QTJava.zip junk from the classpath.
If you don't know what the classpath is and how to set it, read this:
Setting the class path
How Classes are Found
And I'll repeat what the others say: if you are very new to Java, then Java EE will probably be way over your head. First learn the language and the standard API. If you understand that well, start with Java EE. Or do you already know what servlets are, and that you need a servlet container to run them, and how to deploy them etc.?

How to test the simple .java file in cactus
dear friends,
i have use the junit first time .And i am working in weblogic8.1 so i have use cactus .But i face the problem to use it.
1. how to test the simple .java file in cactus.
2.how to run the cactus in weblogic 8.1.Hi,
It is because the converter works on byte code and it only supports a subset of the Java language (see the JC specifications). It is kind of like compiling you code on Java 6 and trying to run it on Java 5. The JCDK outlines the required compiler version.
Cheers,

What's wrong with this simple java file
I am learning java input methods. When I tried to compile the below simple java file, there were two errors.
import java.io.*;
public class MainClass {
public static void main(String[] args) {
Console console = System.console();
String user = console.readLine("user: ");
System.out.println(user);
}The compiler errors:

How to compile and run java files on a mac using command line?
can someone tell me or link me to some article on how to compile and run java files from command line on a mac? I have mac OS X leopard
What do you mean by "where to put them" ? What do you want to put anywhere ?
Have you read Peter's comment in brackets ? Perhaps you have a classpath problem ?

How to compile dunamically genrated java files through java program?
Hi, I have a requirement where i generate java files from WSDL dynamically using wsdl2java jaxbri. I need to compile these files dynamically on the fly and jar it. Everything should happen through java program. Bcos everything is dynamic here, no information is known (like dir, file names ...) until the runtime. Everything is user fed.
the directories may contain other directories with java files. its recursive
i tried com.sun.tools.javac.Main.. but either its not scaling to my needs or i donno how to wok with this.
is there any option to compile the java files as they are created thru JAXBRI (wsdl2java)?
any help is appreciated..
-smy requirement is :
i create java files from wsdl2java (axis).. i need to compile all the java files.. directories with in the directories (recursive)...
as bcos the the java files have inter-dependencies they have to be compiled as a bunch something like (java *.java). I donno how to do this in javac.Main tool
Once all these files are compiled i need to create a jar out of them
Any help is appreciated! -
Error in compilation satge of java files
Hi all
Whenever i m trying to compile java files i m getting this error .I have no idea how to go about fixing this issue. Can any one help me out with this.
Error occurred during initialization of VM
Could not reserve enough space for object heapWell i could go ahead and solve the issue by bringing down the memory allocation at the minimum and maximum level during the compilation stage.
I got the tip from the forum itself where a similar problem had been reported and there this tip was provided.
Earlier in my case i was allocating 1GB of memory for compilation but due to some issue that much space was not being detected on the server. When i pruned that down to 512mb the compilation went ahead without any trouble.
Thanks kelly for geting in involved in geting to know the issue . -

Compiling / Running a Java file in JSP
Hi,
ok, I have a jsp page, which we will call page 1. Once I go to that page, I all I want it to do is compile a certain file.java, and then run the file.java. The user doesn't actually know that this is going on in the background. Page 1 automatically redirects the user to page 2 (also a jsp page).
The java program that I created (that was previously compiled and ran) creates a special javascript file. After running the file.java in page #1, the java file creates a javascript file that will be used in page 2 to display a tree node (group of information).
so, right now, I'm trying to figure out how to write the jsp code that will tell how to compile and run a java file. I was thinking about using javabeans before, but I think you HAVE to actually display the contents of the java file into the jsp (I think). Anyhow, thanks for the help!sorry about being ambiguous before. What I mean by
running a java file was that I already created a java
file. I don't want to hava my java statements inside
the jsp file. I just want the jsp file have a command
in it that would call a java file, tell the java file
to compile and run. All the jsp file would do
(hopefully) is just give commands for a seperate java
file to compile and run. Thanks again for any help!Ok, so this other java file has some entry-point method, like main(), right? So call it...
<%
YourJavaClass.main(appropriateArgumentsGoHere);
%>
or better yet, it's an object you can use:
<%
YourJavaClass x = new YourJavaClass();
x.callSomeMethodHere(withAppropriateArgumentsHere);
x.callAnotherMethodMaybe();
%>
You don't need the jsp file to "compile" this java file, you'd already have compiled it beforehand, and it's class bytecode needs to be in your classpath (on the server side) of course. -

Thanks KT......How are you declaring the class in your JSP? ... are you instantiating it as a bean using the useBean tag, or just instantiating it in your code like normal.
Maybe you could post the relevant JSP code too?
Hello again,
Only the last string is populating after the file has be tokenized. What I'll like to accomplish is passing the very first string in the file. I did not get too far in the JSP file setup because the code is still in it's testing stage, but any help will be highly appreciated.
Here is the JSP code
<%@page import="dev.*" %>
<%@page session="true" language="java" import="java.io.*" %>
<jsp:useBean id="wagerhist" scope="request" class="dev.RoundDetail2" />

Error: code too large for try statement, when compiling a big java file.
Hi,
I have a big java file ( around 16000 lines). When compiling it, I got following error message:
MyMain.java:15233: code too large for try statement
} catch ( Throwable t ) {
In MyMain.java, I just repeat following statements about 1000 times.
try {

System.out.println( "year: Evaluation version is not valid" );
} else {
System.out.println( "year: Evaluation version is still valid" );
} catch ( Throwable t ) {
if ( year >= 2002 ) {
System.out.println( "year: Evaluation version is not valid" );

System.out.println( "year: Evaluation version is still valid" );
I tried 1.3 and 1.4 javac compiler, there was some error.

How to make compiler to compile this code?
You don't. Each method has an absolute limit on the number of byte codes. You have reached that limit. The limit is part of the specification and JVMs will refuse to run classes that exceed the limit. So even if you could compile it, it wouldn't run.
It is quite common for code generators to generate large monolithic blocks of code. Presumably this is how you got to this spot. Modify the code generator to break it into smaller blocks.
If you did it manually then you did it wrong. And you will have to manually break it into smaller blocks. (And re-examine your design since it is probably wrong.) -
Hi,
is it possible to compile a single java class without having to rebuild the complete
application ? If this is not a feature is it going to be available in SP3 ?
Thanks
MarkJust put your java classes in a Java project under your application and
then compile only that project.

Compiling all possible java files
Hi,
I have a project in which not all files/packages compiles but a set of packages compiles always.
Say set of classes which might not compile as 'A' and set of classes which will always compile as 'B'
On frequent basis i need to get update. And I am only concerned about set 'B' but when i compiles my project using ant
compilation fails as 'A' compilation fails and because of that it doesn't go further to compile 'B'.
So how to get eclipse like functionality to compile all possible files?
what i have is
================================
<javac debug="${debug}" deprecation="${deprication}"
optimize="${optimize}" destdir="${build.home}/WEB-INF/classes"
listfiles="${listfiles}" target="${jdk.compliance}"
verbose="${verbose}" srcdir="${src.home}"

source="${src.compliance}">
<classpath refid="compile.path"/>
<include name="**/*.java"/>
<exclude name="HBM/**"/>
<compilerarg value="-Xlint:unchecked"/>
===================================
I do not wish to write all the classes specifically that compiles in ant script.
Thanks in AdvanceTry with failonerror option in your javac.

Problem with getNodeValue() - simple Java XPath question
I am trying to extract the node values from a XML file:
<root>
<frame>
<boxes>
<box>
<spec>22</spec>
<spec>2222</spec>
</box>
<box>
<spec id="BA" value="short"/>
<spec id="BB" value="thin"/>
<spec id="BC" value="black"/>
<spec id="BD" value="full"/>
<spec id="BE" value="7"/>
<spec id="BF" value="deactive"/>
</box>
</boxes>
<circles>
<circle id="CA" value="blue"/>
<circle id="CB" value="green"/>
</circles>
</frame>
</root>I use this code:
XPathFactory factory = XPathFactory.newInstance();
XPath xpath = factory.newXPath();
XPathExpression xPathExpression = xpath.compile("/root/frame/boxes/box/spec");
Object result = xPathExpression.evaluate(doc, XPathConstants.NODESET);
NodeList nodes = (NodeList) result;
for (int i = 0; i < nodes.getLength(); i++) {
System.out.println(nodes.item(i).getNodeValue());
}But only:
null
null
null
null
null
null
null
null
get printed. I would have assumed:
22
2222
null
null
null
null
null
null
since the two first spec nodes contains the above numbers. Any ideas?change this:
XPathExpression xPathExpression = xpath.compile("/root/frame/boxes/box/spec");to this:
XPathExpression xPathExpression = xpath.compile("/root/frame/boxes/box/spec/text()");Need to xpath all the way down to the text of the node.
You could use
System.out.println(nodes.item(i).getTextContent());with your current xpath but if the spec node has children, these will also be included in the output. -
Problem in editing a java file in Webdynpro
Hi All,
I have created a new dc and checked it in the DTR. Now, when I sync it from DTR, and again try to change the implementation of the view, it does not let me do it. I have to go to DTR>inactive dcs-> and explicitly edit the file. I am able to change the layout of the view but not the code.
Please guide me to resolve this issue.
ThanksJust check that ou haven't checkd-in the content of gen_wdp folder. If you have revert them.
Second check: Insert values between //@begin and //@end tags in only. If you enter any where else, the code will be lost.
Select the java implementation and open the navigator view. You see the file selected in the left bowser. Check that the file is writable by clicking on File->Go to Properties-> Info
If it is writable change it to non-writable.
