How to compile a java class via SQL?

Hello,
What is the pl/sql command-line syntax for compiling a java class uploaded to the database?
I'm looking for a command i can use to compile some java code manually similar to:
ALTER TRIGGER SCHEMA.TRG_MYTRIGGER COMPILE;
Thanks

could try dynamic code generation, cglib, asm, eg
http://68.142.231.85/myresults/mycache?u=http%3A%2F%2F
www2.sys-con.com%2FITSG%2Fvirtualcd%2FJava%2Farchives%
2F0702%2Frichards&docid=FToU9dUOIw4HRHa%2F26Zi5Q&.intl
=us&.done=http%3A%2F%2Fmyweb.yahoo.com%2Fmyweb%3Fei%3D
UTF-8%26tag%3Dcode%2Bgenerationhmmmm, yes, bytecode generation is so much simpler, isn't it :-)

How to compile the Java classes generated in JAXB

I am using Windows 2000 Operating System. I found a xjc
batch file on the sun's java forum.
I used that to generate classes from XML. After generating
the classes I could not compile
the classes each depends on other AND THEY REQUIRE BOTH
CLASS FILES.
I will attach the schema file and dtd . Can you explaine me the problem.

How to compile Oracle java strored procedure in Putty

I have created a java strored procedure , which would be invoked by oracle function.
This java stored procedure is get compiled via SQL plus. While compiling by the use of putty , it shows lots of compilation error .
How to compile Oracle java strored procedure in Putty??

You'll need to add the j2ee.jar to your classpath. Usually you'll have to add some jars from your app server to your classpath as well.
For example (using weblogic):
javac -classpath c:\java\j2ee\j2ee1.3.1\lib\j2ee.jar;c:\tools\appserver\weblogic\wl7.1\lib\weblogic.jar
HelloServlet.java

Than how can i get java class by using it's class file?

Hi
After compilation of a java program, it creates a class file.
After getting class file suppose class file has been deleted.
Than how can i get java class by using it's class file?
Thanks in advance.

get a decompiler and run your class file through it--I'll assume you want the source code back and that you are not trying to recover a missing class file by attempting to use the class file that is missing--if it's missing, then I've not a clue on how to get it back by using what is already missing.
BTW: many of your compilers have source control--if it does, just restore your missing file.

How to compile a java file which is in memory?

how to compile the string?
thx

come on ...That was a perfectly valid solution.
Do you know how to call the sun.* compiler? If not then search the forums for it. If that interface still exists (which it might not in newer versions) you then will create a string stream from your class and pass it to that.

Workshop error during compilation of Java class

Hi,
I am starting to use Workshop for development. I am getting the following error when I start the debugger.
I am trying to compile a Java class and don't know how to proceed. Any help is appreciated.
build:
Deleting directory C:\DOCUME~1\name\LOCALS~1\Temp\wlw-temp-23835\wlw_compile55184

I found the answer nested in the documentation. I had to create folders that mirror the package structure and then place the source file in its appropriate folder.

How to compile a Java file

Hi All,
I am extending a seeded CO and when I try to compile it in JDev , it asks for many class files the seeded CO imports.
I have copied all those imported files to my local system and when I try to compile , it still throws an error that some class files used by the classes imported in seeded CO are missing. Now this goes on and on. ( Seems entire server needs to be on my local system).
Now I decided to port the custom CO to server and compile it there. Even this seems to be a hard task for me as the javac command is not working on the server. It throws following exception
Exception in thread "main" java.lang.ClassFormatError: com.sun.tools.javac.main. Main (erroneous method access flags)......................................
Pls suggest how to compile a java file , as downloading entire server classes is a herculean task for me.
Thanks,
Srikanth

Hi Avajain & D.Ram ,
Thanks for the reply.
I have downloaded around 70 dependent class files to local system. Now the CO is getting compiled correctly.
I am extending a region level controller in Payroll page where in I have to default the salary to a predefined value.
This field is having a VO attribute to it. Now can I go ahead and set a value to the MessageTextInput or should I extend the VO to replace the desired value in the place of already queried value.
Thanks,
Srikanth

How to call a Java class from another java class ??

Hi ..... can somebody plz tell me
How to call a Java Class from another Java Class assuming both in the same Package??
I want to call the entire Java Class (not any specific method only........I want all the functionalities of that class)
Please provide me some slotuions!!
Waiting for some fast replies!!
Regards
Smita Mohanty

Hi Smita,
you just need to create an object of that class,thats it. Then you will be able to execute each and every method.
e.g.
you have developed A.java and B.java, both are in same package.
in implementaion of B.java
class B
            A obj = new A();
             //to access A's methods
             A.method();
            // to access A's variable
            //either
           A.variable= value.
           //or
           A.setvariable() or A.getvariable()

How to compile a java file(Servlet) in J2EE v1.3.1

This is my first time using J2EE instead of J2SE!!HOw to compile a java file in J2ee\bin because there is no javac in j2ee and when i compile in J2se i got

import javax.servlet.*;
This mean it doen;t support servlet in J2se!!so how can /what command to compile a servlet java file in j2ee.Thanks

You'll need to add the j2ee.jar to your classpath. Usually you'll have to add some jars from your app server to your classpath as well.
For example (using weblogic):
javac -classpath c:\java\j2ee\j2ee1.3.1\lib\j2ee.jar;c:\tools\appserver\weblogic\wl7.1\lib\weblogic.jar
HelloServlet.java
