Compile java applications,servlets etc.

I am a newbie to java...what do i need to compile java applications,servlets etc.

first you need java developers kit(jdk)
download it
then r.click on my computer and take it's properties
go to advance properties
go to envirinment variable
set variables
JAVA_HOME set to directory where you installed jdk
CLASS_PATH set to the bin in your jdk
then write a java class and save somewhere as .java file
go to command prompt
change directory to where you save java class
and use javac (yourjavafilename) .java command to compile it
wish you all the best

Embedding a java application (servlets) in a portlet

Hi all,
We have an existing java application that we want to run as a portlet in our portal internet site. The application is a simple search form, which submits parameters (search criteria) and returns results, from there can click on a few other things and open some documents etc. We want all this to happen in the same portlet window, rather than opening out to a new window. Can someone please advise if this can be done? We are running release 1 of 9IAS (and we can't upgrade to rel 2 yet) with PDK March. We would preferably like to do this without touching/reprogramming the java code. I have seen a couple of conficting posts in this forum about this - some say can be done, some say can't be done. Please advise:
1. Is there some kind of wrapper that can be applied to keep this app inside the portlet?
2. What other alternatives are there to getting this java app inside?
3. Are there any step by step guides to doing this?
Any help would be much appreciated. Thanks heaps, Sarah

I have tried the URL services, it displays the page fine within the portlet. Just one problem though. The links that are embedded in the HTML will open new windows when clicked. We want them to stay within the portlet. Does something need to be changed in my xml file? I have
<renderer class="oracle.portal.provider.v1.RenderManager">^M
<showPage class="oracle.portal.provider.v1.http.URLRenderer">^M
<contentType>text/html</contentType>^M
<pageExpires>60</pageExpires>^M
<pageUrl>http://www.oracle.com</pageUrl>^M
<filter class="oracle.portal.provider.v1.http.HtmlFilter">^M
<headerTrimTag><center</headerTrimTag>^M
<footerTrimTag>/center></footerTrimTag>^M
<convertTarget>true</convertTarget>^M
</filter>^M
</showPage>^M
</renderer>^M
perhaps I need a different renderer? I saw another post had something in the xml :
<inlineRendering>true</inlineRendering>
that looks promising. Will that deliver the results I'm looking for? Where does it get added?
Thanks for any replies. Sarah

Java application hangs during running java native method

Hello,
There is compiled java application.
It hangs at very begginings.
It was detected that in the beggining a new Frame should be created. Then one java library invokes native method. During invoking of the native method application hangs.
Stack is available only until native method invocation.

I have downloaded from the internet the source code of native method but do not know what I can do with it.
Is it possible to debug native method somehow?
How to detect where the library contans the native method is located?
What other ways can provide more information about reason.
It seems that the problem is related to graphics. Judging by class name "X11GraphicsDevice" it is related to X server. May be some server settings?
The problem is present on SLED 11 machines.
It is not reproduced on SLED 10.
I will be really appreciate for any help.
Thanks in advance.

Distributing my Java Application

Dear Sir/Mdm,
Hi Java experts.... Is there something that i need to watch out for if i want to distribute my compiled Java application in 'jre' format? Is there something that i need to do such that i will not be legally sued?
Thankx

Hi Java experts.... Is there something that i need
ed to watch out for if i want to distribute my
compiled Java application in 'jre' format? Is there
something that i need to do such that i will not be
legally sued?
Normally there is nothing that you can do that be a problem.
However, any of the following could lead to problems
1. You used any of the Sun source code, modified it and then used it.
2. You found some source code or class/jar files on the internet or in a magazine and it did not explicitly say it was free to use. And you are using it as is or modified.
3. You found some source code or class/jar files else on the internet or in a magazine and it explicitly said it was free to use but you had to mention that you were using it. And your docs/gui doesn't say that. (There are actually many variations on this.)

Java application compiles java files in memory

how can I use java application program (that may call method runtime exec or some other techniques) to compile the other java files that were already loaded in memory. (I can not copy those target files to the hard disk with extension java, then compile for security reason).

And once they are compiled, where do you plan to put the compiled .class files? Same security problem, right? Perhaps you planned to load and use them "from memory" somehow? This would be a different security problem. Perhaps you need to rethink what you are doing.

Calling Java application from servlet

Hi !
I'm trying to run a Java application from within a servlet with Tomcat 4. I'm using the Runtime.getRuntime ().exec () method. So the application is run in a different JVM as a subprocess of the servlet. I use ObjectInputStream and ObjectOutputStream and a serializable object to enable communication between the servlet and the application.
I tested the application and the serializable object with another Java application that works as the caller and it works fine. However, replacing the caller application with the servlet I get a StreamCorruptedException. The structure of the caller application and the servlet is the same.
My questions are:
- Is there something I should configure in Tomcat to create a subprocess ?
- What is the cause of the StreamCorruptedException ? How do I get it with the servlet and not with the application ?
- Should I use an environment with the call to Runtime.getRuntime ().exec () ? How do I use it ?
- Is the called application forced to run in my servlet's context ?
- Is there a better way to do this ?
Thanks to all

Here's my code:
1. The serializable object:
// Object Obj
import java.io.*;
public class Obj implements Serializable
public int n;
public Obj ()
n = 0;
public Obj (int n)
this.n = n;
public String toString ()
return getClass ().getName () + " -> (n = " + n + ")";
2. The application Sub (subprogram)
// Application Sub
import java.io.*;
public class Sub
private static File f;
private static FileWriter fw;
public static void main (String [] args)
throws IOException, InterruptedException, ClassNotFoundException
ObjectInputStream ois;
ObjectOutputStream oos;
Obj obj;
ois = new ObjectInputStream (System.in);
obj = (Obj) ois.readObject ();
f = new File ("Sub.txt");
fw = new FileWriter (f);
fw.write (obj.toString ());
fw.close ();
oos = new ObjectOutputStream (System.out);
oos.writeObject (obj);
ois.close ();
oos.close ();
3. The application AMain (caller application)
// Application AMain
import java.io.*;
class AMain
private static File f;
private static FileWriter fw;
public static void main (String [] args)
throws IOException, ClassNotFoundException
Runtime r;
Process p;
ObjectInputStream ois;
ObjectOutputStream oos;
Obj obj, obj2;
r = Runtime.getRuntime ();
p = r.exec ("java Sub");
oos = new ObjectOutputStream (p.getOutputStream ());
obj = new Obj (5);
oos.writeObject (obj);
oos.flush ();
B.comunica (obj);
System.out.println ("AMain sends to Sub: " + obj.toString ());
try
p.waitFor ();
catch (InterruptedException e)
System.out.println ("Subprogram was interrupted");
System.out.println (e.toString ());
ois = new ObjectInputStream (p.getInputStream ());
System.out.print ("Sub sends to AMain: ");
obj2 = (Obj) ois.readObject ();
System.out.println (" " + obj2.toString ());
oos.close ();
ois.close ();
p.destroy ();
4. The servlet SMain (the calling servlet)
// Servlet SMain
import javax.servlet.*;
import javax.servlet.http.*;
import java.sql.*;
import java.io.*;
import java.util.*;
public class SMain extends HttpServlet
public void doPost (HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
Runtime r;
Process p;
ObjectInputStream ois;
ObjectOutputStream oos;
Obj obj, obj2;
int state, i;
res.setContentType ("text/html");
ServletOutputStream out = res.getOutputStream ();
out.println ("<html>");
out.println ("<head><title>Sub</title></head>");
out.println ("<body>");
out.println ("Invoking subprogram...");
out.println (" ");
try
r = Runtime.getRuntime();
p = r.exec ("java -cp .;c:\\Programs\\Apache~1.0\\webapps\\SMain\\WEB-INF\\classes Sub");
out.println ("...invoked ");
oos = new ObjectOutputStream (p.getOutputStream ());
obj = new Obj (5);
oos.writeObject (obj);
oos.flush ();
out.println (" SMain sends to Sub: " + obj.toString () + " ");
try
p.waitFor ();
catch (InterruptedException e)
out.println (" Subprogram was interrupted ");
out.println (" " + e.toString () + " ");
state = p.exitValue ();
out.println (" Subprogram state: " + state + " ");
ois = new ObjectInputStream (p.getInputStream ());
out.print (" Sub sends to SMain: ");
obj2 = (Obj) ois.readObject ();
p.destroy ();
catch (SecurityException e)
out.println (" SecurityException ");
out.println (" " + e.toString () + " ");
catch (IOException e)
out.println (" IOException ");
out.println (" " + e.toString () + " ");
catch (Exception e)
out.println (" Exception ");
out.println (" " + e.toString () + " ");
out.println ("</body>");
out.println ("</html>");
So, as you can see, both application AMain and servlet SMain invoke application Sub and pass it the serializable object Obj. Oddly enough, application AMain works fine whereas servlet SMain throws a StreamCorruptedException exception.
johnpoole said:
�It's hard to guess what would cause the exception without seeing code, but the interaction between the processes would differ from that between two applications, because the servlet process is started with a different class loader. I'm not sure which one the jvm started by the call would use.�
How can I enforce that a System classloader be used in the call to Runtime.getRuntime ().exec () ? (I mean by System classloader a classloader equals to the one applications are launched from console).
johnpoole said
�Is there a reason why you aren't starting the second process manually and then connecting to it on a port?�
The idea is providing a Web interface for an application running in the server. The servlet is used to restrict access to this application but once access is granted (passing the servlet) the application should not be constrained.

Pl help ! ! Opening a servlet URL using stand aline java application

Hi Guys, I have a standalone java application. This application will get executed after some by some thread. What I want to do is when this java application is executed, automatically open a URL in internet explorer which is of my servler/jsp and pass the parameters to this servlet/jsp. This servler jsp will intern use EJB and other services to get the data and display it.
How should I automatically open a IE window and pass parameters using this standalone application.
Pl help ! ! !
thanks , Ava

do you want to open internet explorer, or just access the servlet without internet explorer?
if you want to use internet explorer, you'd want to use
Runtime.exec,
if you want to access the Servlet w/o ie, you would use
URL, and HttpURLConnection classes

Compiling Java Servlet with Depricated Methods

I have a problem of compiling Java servlets that contain depricated methods. If you compile against modern version of servlet.jar I see depricated methods error messages and if I use a very old servlet.jar it cannot find newer methods. What is is the best solution in this case?
Thank you,
Boris.

The best thing to do would be compile your code with the -depreciated option to find which methods have been depreciated and the refactor your code to remove them.
The next best thing is to ignore the messages (they are warnings not errors) and your code should still work

Compiling java code from a running java application

How does compiling of java code from a running java application work?
I found a class: com.sun.tools.apt.main.JavaCompiler
but cannot find any documentation of how this class works.

How does compiling of java code from a running java
application work?Probably most reliably using Runtime.exec().
I found a class:
com.sun.tools.apt.main.JavaCompiler
but cannot find any documentation of how this class
works.For a purpose. You are not supposed to use this class. With the next JRE release or implementation, it might not exist anymore - it's not part of the standard API.

Steps to execute servlets on Sun Java Application Server

Hi
Could u tell me how to deploy servlets files and how to execute
In specs. the ask us to start cloudscape database server
In my Sun Java Application Server installations, i am not find even a single name as cloudscape
Please anyone guide me get the servelts to execute
thank u

What specs do you refer to?
Sun Java System Application Server does not include Cloudscape, nor is it required. SJSAS does include a development copy of Pointbase DB Server.
To deploy your servlet application you will need to package them into a WAR file (Web Archive). Then you can either use asadmin CLI or the admin gui to deploy the WAR. The steps are included here: http://docs.sun.com/source/816-7150-10/dwdeploy.html
Now I'm going to assume you application uses Cloudscape. To get that piece running you will need to download and install Cloudscape. You will also need the JDBC drivers for Cloudscape. Copy the JDBC driver jar file to either the <serverinstancedir>/lib directory or modify the JVM settings to include that jar file. Restart the Application Server. You will also need to add a JDBC Resource & Connection Pool. In the admin, create a new connection pool (probably called Cloudscape). Use the appropriate settings for classname and add any additional properties that are necessary (Usually URL, User, Password). Now create a JDBC Resource using that Connection Pool. Make sure the JNDI name matches what your application expects.
Now just access the URL for the application

Compiling java servlet programs

i have Tomcat 5.0 and SDK 1.5 . I am able to compile java programs. But in servlet programs the compiler is unable to recognize the javax.servlet package(the code below). I have pushed all the JAR files of TOMCAT to the CLASSPATH . But nothing has changed.
javax.servlet.*;
javax.servlet.Http.*;

hi,..
javax.servlet.Http.*; should be javax.servlet.http.*; !
even though you have put the jar files in the classpath .. does it point to servlet-api.jar ? if it does.. it should work. Also try out specifing the classpath using the -cp while compiling the servlet program .

Hi Sarang,
It seems you are following the two basic pre-req.
It may be now possible that your browser might be not allowing cookies. Which browser are u using? Version etc?
Right now u can try two things:
1) When you have logged into portal, type the following command in the adress bar "javascript:alert(document.cookie)". This will give u a popup displaying the cookies formed when logged into portal
2) Use some software like HTTPWatch or ieHeaders and find out the details. It will give you all the cookie details etc.
You should be able to see the JSESSIONID, MYSAPSSO2 cookies...Let me know the result of above..
Regards
Gaurav

Compile java applications,servlets etc.
