AutoType Compiler Class Path

I am using NetBeans with their Ant integration. If I put the
"webservices.jar" file in the IDE class path and then run my Ant build
script, it complains that it can not find the autotype task. So what I do
is specify the classpath as part of my task definition in Ant.
But the problem arises when the autotype task attempts to compile its
generated java files. With debugging turned on in Ant, I see that the
compiler's class path is inherited from the IDE. So it does NOT contain the
webservices.jar and therefore pukes when it compiles the generated java
files.
Bottom line is, I need to specify the compiler class path that autotype will
use to compile its generated java files. Is there any way to accomplish
this? Has anyone else had luck with running autotype under NetBeans???
Thanks In Advance,
Pat

You need both weblogic.jar and webservice.jar in your classpath.
Then try this :
<target name="autotypetest">
<autotype schemaFile=" ....">
<classpath>
<pathelement path=" "/> --- You can specify complete
classpath here for compiler to use.
</classpath>
</autotype>
</target>

Java Class path for Oracle package compilation

Hello
I am trying to send mail with file attachment, this part is
done by java program, it is compiled & working fine.
I am trying to compile the same java program at SQL prompt so
that I can build a package to execute that Java program from
Oracle. As java prog requires other class files
(javax.mail.*,javax.mail.internet.*,javax.activation.*) to be
include , those class path is set at their respective location
of OS.
Other Java programs are compiling fine from SQL but for this
mail prog, it is giving error as it is not finding the location
of the include files.
Can anyone tell me from which class path does Oracle 8i compiles
Java program ? any additional information reqdng this issue ?
thanks

Hello Suresh Vemulapalli
Thanks for replay & suggestion, I compiled using loadjava on
OS & it is working fine

Hi,
The problem you are referring above is definitely due to the java embedding you are using.
This seems to be a simple Hello World example, and if you are looking for the same to work, you can simply use an assign activity to concat the input with the Hello world.
If you are trying to use a java embedding activity which has some custom java coding in it, please refer to the following:
Make sure all the dependent classes are explicitly mentioned with their packagename.ClassName.
Also , make sure you make all the classes as jar and include it in sca-inf\lib directory of the code.
a) See that your external / dependent Java applications dependent Jar files are copied in csa-inf/lib (e.g all jars like log4j, apache jars, wickets jar etc etc etc )
b) also make sure u deploy the dependent java application as JAR using jdeveloper deploy wizard.... for example archive1.jar and then copy this jar as well in sca - inf / lib folder
it will work ....
Thanks,
Deepak.

Package and class path

for two yrs i am trying to get package right but no result
i am using window 98
i have my jdk in d:\jdk1.2\bin; and this works fine if i do not try to use package;somtimes it works well half way with package!
suppose i want to create a package called rubberband and put classes in it
i created a folder called rubberband in d:\ and then
package rubberband;
import java.awt.*;
public class RubberbandTest extends Frame{}
class RubberbandTestPanel {}
class Colorchoice{}
this is one unit
and there are other classes
package rubberband;
import java.awt.*;
abstract class Rubberband {}
package rubberband;
import java.awt.*;
class RubberbandPanel extends Rubberband {}
and so on
i opened executive.bat and added to class path as follows:
path:d:\rubberband\bin;before the already existing d:\jdk1.2\bin;
then when i come to compile and run the program i have problems
like:class so and so not found
please help please step by step tell me what to do

Another sample might answer your "different location" question.
Suppose program YourProg in package yourPkg located in directory C:\javaprogs needs to access a class file ExtraClass in package extraPkg in directory C:\differentDir.
1) Of course the source file must exist in file
C:\javaprogs\yourPkg\YourProg.java
and
C:\differentDir\extraPkg\ExtraClass.class must exist.
2) Inside the YourProg source, you must import ExtraClass:
import extraPkg.ExtraClass;
3) To compile YourProg, you must include location of extraPkg.ExtraClass in the classpath (or the compiler will complain about the inport line above):
(a -- from C:\javaprogs directory): javac -classpath C:\differentDir yourPkg\YourProg.java
(b -- from any directory): javac -classpath C:\javaprogs;C:\differentDir yourPkg\YourProg.java
4) To run YourProg (assuming it contains a main method), you must include all locations in classpath:
(a -- from C:\javaprogs directory): java -classpath .;C:\differentDir yourPkg.YourProg
(b -- from any directory): java -classpath C:\javaprogs;C:\differentDir yourPkg.YourProg
If you get a NoClassDefFoundError, that means that the java was run without the proper location included in the classpath passed to the -classpath argument. The -classpath argument should be ';'-separated and contain no spaces (so if a long directory name contains space you should enclose in double quotes, as this example:
java -cp "C:\Program Files\somedir;C:\anotherdir" NameOfAClass

Servlet class path

Can anybody tell me what is the exact path to put the servlet class file in
tomcat 4. I was reading a book called more servelet by Marty Hall and its metioned there that i can put them in install_dir/webapps/ROOT/WEB-INF/classes but when i browse to WEB-INF folder there is no folder named classes there.
Please help.

firsly i installed jdk 1.3 on my computer. Then i installed tomcat 4. Then i changed port 8080 in server.xml to 80. Then i set the JAVA_HOME path to point to jdk1.3 folder. Then i setup the class path to D:\Documents and Settings\Ashi\Desktop\tomcat\apache-tomcat-4.1.34\apache-tomcat-4.1.34\common\lib\servlet.jar
Then i downloaded a source file named HelloServlet.java from author's website and compiled it. It compiled successfully. I copied the HelloServlet.class file to the classes directory that you asked me to create. Then i opened my browser and typed http://localhost/servlet/HelloServlet and getting error HTTP Status 404

Jar's manifest Class-Path option

Hey, hopefully this is my last question for a while.
I downloaded a custom look and feel that's packaged in a jar file.
Here's the directory structure.
Main-Program\*.class
Main-Program\MyProgram.jar (the created jar)
Main-Program\Data\kunststoff.jar (downloaded look&feel jar)
I can compile the class files like this:
javac -classpath .;Data\kunststoff.jar MainClass.java
and run it like this:
java.exe -classpath .;Data\kunststoff.jar MainClass
This works fine. But I want my program to be an executable jar.
So I create the exec. jar like usual
jar cf0 MyProgram.jar *.class
jar umf mainclass.txt MyProgram.jar
When I package the jar using the manifest file I include the Class-Path var:
Manifest-Version: 1.0
Main-Class: Database
Class-Path: .;Data\kunststoff
Now when I try to execute the jar it gives me the error:
"Could not find the main class. Program will exit!"
Any ideas? thanks.

Manifest-Version: 1.0
Main-Class: Database
Class-Path: .;Data\kunststoff>
Better change that to "Class-Path: Data/kunststoff.jar"
(http://java.sun.com/docs/books/tutorial/jar/basics/manifest.html)
And remember to have a line break after it..
Now when I try to execute the jar it gives me the
error:
"Could not find the main class. Program will exit!">
But the main class should still be found even if the class-path entry was not totally correct, does Database.class show in jar tf MyProgram.jar?

Possible 'Class Path' Issues

Hi Guys,
I have problems compiling a file and I suspect it could be something related to classpaths. I am using NetBeans 6.9.1 as my IDE. When I set JDK 1.6 as my platform and complile, there are no issues, the programs compiles fine.
My 'classpath' and 'path' are as follows:
classpath:
.;C:\Program Files\Java\jre1.6.0_07\lib\ext.;c:\java\classes;
path:
\....\....\....C:\Program Files\Java\jdk1.6.0_21\
If I were to set the JDK as in 1.5, I seem to get the follwing error:
' cannot access org.red5.server.api.IScope
bad class file: C:\Program
Files\Red5\red5.jar(org/red5/server/api/IScope.class)
class file has wrong version 50.0, should be 49.0
Please remove or make sure it appears in the correct subdirectory of the classpath.
import org.red5.server.api.IScope;
1 error
To rectify the problem I maded changes to my classpath and path, and yet the problem persists. The changes I made
are as follows:
classpath:
.;C:\Program Files\Java\jre1.6.0_07\lib\ext.;C:\Program Files\Java\jre1.5.0_22\lib\ext.;c:\java\classes;
path:
\....\....\....C:\Program Files\Java\jdk1.6.0_21;C:\Program Files\Java\jdk1.5.0_22;C:\....\
I hope someone can advise me on how I get rectify the problem and get the program to compile with JDK 1.5. Thanks.

he wants to use JDK 1.5.Do read the thread before you post. He is* using JDK 1.5 when he gets the error message. He said so. This is the problem.* Not the solution. When he uses 1.6 he doesn't get the error.
His environment is a bit messed up because he has PATH entries for both JDK versions.There is precisely zero evidence for that assertion.
If he wants to compile and test with JDK 1.5, then removing 1.6 would make sense.No it wouldn't. He is using classes compiled for 1.6 with a 1.5 compiler. His problem is with red5.jar(org/red5/server/api/IScope.class) whose class version is 50.0. It's all written there above. If he wants to use that .jar file he has to use 1.6. Or else recompile that .jar file with 1.5, if he has the sources.

Jar: Manifest-Attribute "Class-Path"

I've got a problem with the Class-Path-attribute of the JARs manifest-file. So I've written a real simple application to test where the problems occure... but even this trivial app does not work!
The execution starts at "Starter.java":
public class Starter{
      public static void main(String args[]){
            packageOne.Caller.callWriter();
}The class "Caller" is in a JAR ("Caller.jar") in the same directory as Starter.java.
Caller.java:
package packageOne;
public class Caller{
      public static void callWriter(){
            packageTwo.Writer.write("Write this");
}The class "Writer" is in a JAR ("Writer.jar") in the same directory as Starter.java and Caller.jar.
Writer.java:
package packageTwo;
public class Writer{
      public static void write(String message){
            System.out.println(message);
}The file Caller.jar consists of Caller.class and the Manifest.mf. The package-structur/the path seams to be all right.
The file Writer.jar consists of Writer.class and the Manifest.mf. The package-structur/the path seams to be all right.
If I invoke the Starter with:
java Starter -classpath Caller.jar;Writer.jareverything's fine.
Now, I added the following line to the Manifest.mf of Caller.jar:
Class-Path: Writer.jar(with one empty line between Manifest-Version: 1.0 and the new line.
So... shouldn't it be possible now, to invoke the application with:
java Starter -classpath Caller.jar ???
It doesn't work. So: what have I misunderstood?
(The error message is:
Exception in thread "main" java.lang.NoClassDefFoundError: packageTwo/Writer
      at packageOne.Caller.callWriter(packageOne/Caller.java:5)
      at Starter.main(Starter.java:3)

Hmmm, I tested it and here are the command I ran and their results. Try doing the same on your computer:aleph% mkdir packageOne
aleph% mkdir packageTwoThat created the directories.aleph% cat > Starter.java
public class Starter{
      public static void main(String args[]){
            packageOne.Caller.callWriter();
aleph% cat > packageOne/Caller.java
package packageOne;
public class Caller{
      public static void callWriter(){
            packageTwo.Writer.write("Write this");
aleph% cat > packageTwo/Writer.java
package packageTwo;
public class Writer{
      public static void write(String message){
            System.out.println(message);
}That created the source files: Starter.java in the current directory, Caller.java under packageOne and Writer.java under packageTwo. Next the compiling and creating the manifest file:aleph% javac Starter.java
aleph% cat > MF
Class-Path: Writer.jarThat created additional info to be included in manifest file and put it in a file called MF.
Then I package "caller.jar" with the manifest and "Writer.jar" without it:aleph% jar -cmf MF caller.jar packageOne
aleph% jar -cf Writer.jar packageTwoDelete the package* directories so java wont get confused...aleph% rm -r package*And finally run the thing. Remember that the path separator is : in unix but ; in DOS, if that is what you are using.aleph% java -cp .:caller.jar Starter
Write thisNo problems anywhere. What are the steps you did?

Hi,
I am using J2EE SDK 1.4 Server and deployed a Stateless Session Bean and used a JSP page as Web Deployment component. When I deploy the application no error is given but when I access application using the given web context name the following error is displayed on the browser.
type Exception report
message
description The server encountered an internal error () that prevented
it from fulfilling this request.
exception
org.apache.jasper.JasperException: Unable to compile class for JSP
No Java compiler was found to compile the generated source for the JSP.
This can usually be solved by copying manually
$JAVA_HOME/lib/tools.jar from the JDK
to the common/lib directory of the Tomcat server, followed by a Tomcat restart.
If using an alternate Java compiler, please check its installation and
access path.

Jar class path in solaris

Hi
I am new to solaris environment. I have a java file which is dependent on xerces.jar. to compile the file i need to set the classpath. pleas let me know how to set class path for xerces.jar which is in usr/raj/ folder structure of solaris machine.
if there is any on the fly method of setting classpath plz let me know....
thanks a lot
raj

What shell are you using?
csh: setenv CLASSPATH ${CLASSPATH}:/usr/raj/xerces.jarsh/ksh: CLASSPATH=${CLASSPATH}:/usr/raj/xerces.jar
export CLASSPATH

User defined classpath setting using "-Djava.class.path="

Hello,
I am invoking a JVM from a C++ application ( say A ) which inturn will be started by another C++ application ( say B ).
The class path for the JVM is set by "-Djava.class.path=" option in application 'A' which will actually supplied by parent application 'B'.
I want to know how to do it ?
I tried with the following things but it doesn't work.
// the application 'A' gets classpath string from appication 'B' the "classpath" variable ( which is a string ) gets from application 'B'
// this is in application 'A'
// "classpath" variable in application 'A' holds the class path string optained from application 'B'
"-Djava.class.path=" classpath ; ---(1)
// "-Djava.class.path=" %classpath% ; ---(2)
// "-Djava.class.path=classpath" ; ---(3)
All the above tries are failed in first 2 tries the application even doesn't get compiled and in third try the appilcation doesn't set the classpath even though it is get compiled.
Do any one have any Idea !!

Hi,
I am not quite sure if I got your problem correctly...
Your application A has a variable called classpath containing the classpath recieved from B. right? Now you want to call the JVM with that.
I think what you got to do is something like
sprintf(myclasspath, "-Djava.class.path=%s", classpath);
this will build the correct string for the JVM in myclasspath. And that one can be used to call the JVM.
Does this sound right??

Compiling class in a package

Hi,
for some reason i can't understand i am having a hard time compiling some of my classes in a particular package.
Lets say my packages are
classes\arm\matrix\util\
classes\arm\pdm\
I have numerous .class files in the util directory which are precompiled under the matrix\util dir structure.
I have some classes in pdm folder and in their first line i gave
package arm.pdm;
I am trying to compile classes in arm\pdm
My classes in arm\pdm can read the classes in the matrix\util directroy
but they can't understand the classes in the same dir
For example if i have --
arm\pdm\P1.java and arm\pdm\P2.java
so if i complie P2.java and am using P1.class in it and i get an error
saying cannot resolve symbol P1.
This is the command am using to compile the class
c:\server\webapps\test\web-inf\classes\arm> javac -classpath . pdm\P2.java
Please help. .....
Any help would b greatly apprectiated
thanks

Any help would b greatly apprectiatedDo you have the following file?
c:\server\webapps\test\web-inf\classes\arm\arm\pdm\P1.class
That is how your class path is set.
Try one of the following for your class path
-classpath ..
-classpath c:\server\webapps\test\web-inf\classes

Javac / Manifest Class-Path

Hi guys,
I have problems with javac not finding classes when I use the extension mechanism.
I have several jars: abc.jar def.jar ghi.jar ...
To simplify the classpath when trying to compile another project with these jars, I use the extension mechanism and create a new jar (alphabet.jar) containing only a manifest file:
Manifest-Version:1.0
Class-Path: abc.jar def.jar ghi.jar ...The following works fine (assuming for example that abc.jar contains org/alphabet/Abc.class):
> java -classpath alphabet.jar org.alphabet.AbcBut this fails:
> javac -classpath alphabet.jar Test.java
Test.java:1: package org.alphabet does not exist
import org.alphabet.Abc;
1 errorTest.java:
import org.alphabet.Abc;
public class Test {}I've searched on google and co. for more information but could not get anything. Sun's documentation http://java.sun.com/j2se/1.4/docs/tooldocs/findingclasses.html doesn't mention anything about javac not using the extension mechanism.
This seems to happen on all JDKs (1.2.2, 1.3.1, 1.4 at least).
Thanks in advance for your help!

hi again,
the next what you should know is that a package has to really exist as directories on your harddisk by compile- and runtime and the name of the class-file needs to be the same name as the class-name in it.
example:
c:\javalib\org\alphabet\Abc.java
c:\javalib\Test.java
compile both with 1 javac-command
c:\>cd c:\javalib
c:\javalib\>javac Test.java
all imported libs (c:\javalib\org\alphabet\Abc.java) will be automatically compiled with this command. you will have now 2 class-files:
c:\javalib\org\alphabet\Abc.class
c:\javalib\Test.class
now you make a 'manifest'-file for creating a autostartable jar-file:
create a textfile 'mymanifest.txt' (name is not important) in the root of your projekt with the following content:
c:\javalib\>mymanifest.txt
Manifest-Version: 1.0
Main-Class: Test
Created-By: Your Name
(if the start-class is in a package you have to write:
Main-Class: mypackage.Test)
now you can make a executable jar (a jar with a manifest) with the command:
c:\javalib>jar cvfm alphabet.jar mymanifest.txt .
(dont forget the last point!)
now you can run the jar simply with:
(it's now a java-executable)
c:\javalib>java -jar alphabet.jar
hope to help

oliver scorp
ps: a jar-file is nothing other than a zip-file, rename it and try it out. you will see that the pathes still exist in the compressed file.
pps: plz dont forget my dukes!
