Unable to execute sh file from java file on the solaris

hi all
i have written a java program through which i want to shutdown the weblogic server on the solaris.
I have written following code
static Runtime objruntime = null;
objruntime = Runtime.getRuntime();
Process objprocess=null;
String url = "/home/xxx/xxx/xxxx/xxxxx/stopWebLogic.sh";
try {
               objprocess = objruntime.exec(url);
               objprocess.destroy();
               System.out.println("Server shutdown OK..");
          } catch (Exception e) {
     System.out.println("Error executing Cedera Server shutdown." + e);
I am able to execute the above code on the linux 7.1 means server get shutdown forcefully.
But when i am trying to execute above code on solaris, server is not getting shutdown.
Can anybody please help to solve this problem.
Thanks in advance
regards
andy

we didn't got what you are trying to say..
what i want to achieve is...
we are having one condition check in Startup class if that condition becomes false we have to stop the weblogic from starting up.
if we execute same command posted previously from shell directly its' working fine.
we are using "csh" shell. we have also tried to execute the command as follows - " csh /home/xxxx/xxx/xxx/xxxxx/stopWebLogic.sh"
but no achievement.
it seems that "objruntime.exec(url);" is not able to invoke the shell script "stopWebLogic.sh". We have also checked the execute permission for the same.
Neither we are getting any error nor any message.
can u please give us some guide lines on how to achieve this.

Creating .jnlp files from .java files

Last resort: Ask on the forums. I'm having a lot of trouble creating .jnlp files with only a .java file. For some reason if I do create project, the project does not run correctly, but when I make the file and run the file alone, it works perfectly fine. Most of the tutorials that I have read online ask me to do weird manifest .class stuff (in order to make JAR files, which i have failed to do even after attempting to make one after 3 hours). And still, when it comes to make the .jnlp file, I don't quite understand anything. When putting it on the web, I'm planning not to use php (html is in my mind right now), and I have aborted every single attempt at making the JAR files and whatnot.
At this point, I'm not asking for anything other than a link to a tutorial that actually works, because all that I have tried (for the JAR files, especially) have been giving me errors. By the way, one really bothersome output that comes up is the "illegal option: j" when I use the Tool for the JAR file, and I have no idea what that means--I google it and find nothing. The .java itself extends JPanel, so it isn't really an applet.
How to: Run an Applet
Create an Applet Class by clicking File > New > File > File Type > Java Classes > Applet Class.
Enter a name and path for the applet and click Finish.
Build the file by pressing F7.
Create an Applet HTML file by clicking File > New > File > File Type > Other > HTML Applet.
Enter a name and path for the applet and click Finish.
Open the HTML file in JCreator and modify the applet tag to match the name of the applet class.
Open the Project Settings window and select the HTML file as the Run parameter.
Click the Run Project button.It isn't really a code, but I tried doing this and the HTML Applet said code = ".class" Again, I don't have a class for the file. And when you do the "File > New > File > File Type > Java Classes > Applet Class," you get the .java file and a folder that says "components, with two classes in it. I was completely befuddled.

How to make exe files from java files

Ohhh, so you thought you were going to answer that question? Well I already know the answer, i.e. all the tricks with the jar files or the programs which convert java programs into executable programs.
The reason why I asked this question was to start a discussion concerning question which are frequently asked in the forums. Wouldn�t it be nice to have like statistics over the most faq here, and of course one or several pages with the answers to these questions? This would solve 2 problems:
1) The person who wants to ask the question can find the answer and the solution quickly.
2) The forums would not be packed with the same questions all the time.
I mean, you must admit that the questions regarding �exe files� are asked a lot of times.
Happy coding to ya all!
/TM

Yeah thats my point! these questions should be moved
to a special page, where the answer to theam areDid you the whole message? I said there are FAQs.

Executing batch file from Java stored procedure hang

Dears,
I'm using the following code to execute batch file from Java Stored procedure, which is working fine from Java IDE JDeveloper 10.1.3.4.
public static String runFile(String drive)
String result = "";
String content = "echo off\n" + "vol " + drive + ": | find /i \"Serial Number is\"";
try {
File directory = new File(drive + ":");
File file = File.createTempFile("bb1", ".bat", directory);
file.deleteOnExit();
FileWriter fw = new java.io.FileWriter(file);
fw.write(content);
fw.close();
// The next line is the command causing the problem
Process p = Runtime.getRuntime().exec("cmd.exe /c " + file.getPath());
BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line;
while ((line = input.readLine()) != null)
result += line;
input.close();
file.delete();
result = result.substring( result.lastIndexOf( ' ' )).trim();
} catch (Exception e) {
e.printStackTrace();
result = e.getClass().getName() + " : " + e.getMessage();
return result;
The above code is used in getting the volume of a drive on windows, something like "80EC-C230"
I gave the SYSTEM schema the required privilege to execute the code.
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'java.io.FilePermission', '<<ALL FILES>>', 'read ,write, execute, delete');
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'writeFileDescriptor', '');
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'readFileDescriptor', '');
GRANT JAVAUSERPRIV TO SYSTEM;
I have used the following to load the class in Oracle 9ir2 DB:
loadjava -u [system/******@orcl|mailto:system/******@orcl] -v -resolve C:\Server\src\net\dev\Util.java
CREATE FUNCTION A1(drive IN VARCHAR2) RETURN VARCHAR2 AS LANGUAGE JAVA NAME 'net.dev.Util.a1(java.lang.String) return java.lang.String';
variable serial1 varchar2(1000);
call A1( 'C' ) into :serial1;
The problem that it hangs when I execute the call to the function (I have indicated the line causing the problem in a comment in the code).
I have seen similar problems on other forums, but no solution posted
[http://oracle.ittoolbox.com/groups/technical-functional/oracle-jdeveloper-l/run-an-exe-file-using-oracle-database-trigger-1567662]
I have posted this in JDeveloper forum ([t-853821]) but suggested to post for forum in DB.
Can anyne help?

Dear Peter,
You are totally right, I got this as mistake copy paste. I'm just having a Java utility for running external files outside Oracle DB, this is the method runFile()
I'm passing it the content of script and names of file to be created on the fly and executed then deleted, sorry for the mistake in creating caller function.
The main point, how I claim that the line in code where creating external process is the problem. I have tried the code with commenting this line and it was working ok, I made this to make sure of the permission required that I need to give to the schema passing security permission problems.
The function script is running perfect if I'm executing vbs script outside Oracle using something like "cscript //NoLogo aaa1.vbs", but when I use the command line the call just never returns to me "cmd.exe /c bb1.bat".
where content of bb1.bat as follows:
echo off
vol C: | find /i "Serial Number is"
The above batch file just get the serial number of hard drive assigned when windows formatted HD.
Same code runs outside Oracle just fine, but inside Oracle doesn't return if I exectued the following:
variable serial1 varchar2(1000);
call A1( 'C' ) into :serial1;
Never returns
Thanks for tracing teh issue to that details ;) hope you coul help.

Starting exetutable java file from java code

Hi I was wondering how I can start a executable java file from java code?
thanks

Hi Mkaveli,
Yes, it's possible. If you have a JAR executable, you've just to call the main method of its starter class. For a simple executable class, just call its main method.
This way :
SomeStarter.main(null); // if there's no argumentSmall precision : the executable JAR or class must be specified in the classpath of your application.

How to modify an existing xml file from java code.

Hi
I have worked on creating a new xml file from java code using xmlbeans.But if i try to modify an already existing file using java code I am unable to get errorfree xmlfile.
For example if xml file(studlist.xml) is as below:
<?xml version="1.0" encoding="UTF-8"?>
<StudentList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="D:\kchaitanya\xmlprac1\abc\Studlist.xsd">
     <Student>
          <Name>ram</Name>
          <Age>27</Age>
     </Student>
<Student>
          <Name>sham</Name>
          <Age>26</Age>
     </Student>
</StudentList>
Now suppose i have set name to victor using student.setName,
and set age to 20 using setAge from javacode,
the new xml file is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<StudentList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="D:\kchaitanya\xmlprac1\abc\Studlist.xsd">
     <Student>
          <Name>ram</Name>
          <Age>27</Age>
     </Student>
<Student>
          <Name>sham</Name>
          <Age>26</Age>
     </Student>
</StudentList>
<Student>
          <Name>victor</Name>
          <Age>20</Age>
     </Student>
As observed this is not a valid xml file.But how can i modify without any errors?

I know it's an old post, but I found this while doing a google search for something else, and don't like to leave it un-aswered
Just in case anyone has a similar problem... In this case the new elements have been appended outside of the root element
What you need to do is first get the root element and then append the new children to that, there are several ways of getting the root element, which depend on what you want to do with the elements you get back here's a simple (incomplete) way.
// gets the root element of the specified file (code not shown)
Element rootElement= new SAXReader().read(file).getRootElement();Then just append the new elements as below (this is non-generic code and would need to be modified for your situation)
// write a new student element
Element student = document.createElement("Student"); // creates the new student
rootElement.appendChild(student); // ***appends it to the root element***
Element name = document.createElement("Name"); // creates the name element
name.appendChild(document.createTextNode("Fred")); // adds the name text to the name element
student.appendChild(name); // appends the name to the student
Element age= document.createElement("Age"); // creates the age element
age.appendChild(document.createTextNode("26")); // adds the age text to the age element
student.appendChild(age); // appends the name to the studentThen flush ya buffers or whatever and write the file
