Execute java commands through java code

Hi guys,
I want to run a java class from another class.
I tried like this..
Runtime.getRuntime("java C:\test2");But test2 did not run.
But I could execute this command sucessfully.
Runtime.getRuntime("javac C\test2.java");
I could see class file generated for this.
Please suggest me how to run a java class .....
Thanks in advance.

Hi guys,
I want to run a java class from another class.
I tried like this..
Runtime.getRuntime("java C:\test2");But test2 did not
run.Because the JVM (the java command) does not take a file as its argument. It takes a class name. You'd want something like java -cp C:\ test2
But I could execute this command sucessfully.
Runtime.getRuntime("javac C\test2.java");Because javac, unlike java, does take files (rather than a class name) as its argument.

Execute dos commands through java

Hi,
Im trying to execute dos commands through java like
          try {
               java.lang.Runtime.getRuntime().exec("cmd /c cls");
          }catch(IOException e){
               System.out.println(e.getMessage());
          }Not sure if its possible? however
open notepad would work
          try {
               java.lang.Runtime.getRuntime().exec("notepad");
          }catch(IOException e){
               System.out.println(e.getMessage());
          }Im trying to execute a cls commands to clear screen but without luck.

The question is, which shell do you want to clear?
I don't really know, but it could be that Runtime.exec executes its command in a new shell window...

Hi, thanks for your reply so far. I tried the following code:
     public boolean executeCommand() {
          boolean success = true;
          for (int i = 0; i < 5; i++) {
               Process p = null;
               try {
                    p = Runtime
                    .getRuntime()
                    .exec("ls");
                    InputStreamReader inR = new InputStreamReader(p
                              .getErrorStream());
                    BufferedReader buf = new BufferedReader(inR);
                    String line;
                    while ((line = buf.readLine()) != null) {
                         System.out.println(line);
                    p.destroy();
               } catch (Exception e) {
                    System.err.println(e.getMessage());
                    e.printStackTrace();
                    success = false;
               } finally {
                    p = null;
          return success;
     }However, it still throws the same exception. Yes, I put it in a tight loop, but not recursively.

Java.lang.NoClassDefFoundError when executing JAVA code

Hy everyone,
Trying to execute some java code through forms I got this error when running my program : java.lang.NoClassDefFoundError : simple (where simple is a java class I developped).
These are the steps I followed:
1- Devopping a simple JAVA class (simple.java) and compiling in JDK 1.4 (for compatibilty with forms 10.1.2.0.2)
2- Creating the JAR file
3- Copying the JAR file in <ORACLE_HOME>\forms\java
4- Adding the adress of the JAR file in CLASSPATH (environment variable of the server)
5- Adding the adress of the JAR file in CLASSPATH (environmental file of OAS default.env)
6- Importing the JAVA class trought forms builder (program>>import java class)
7- Invoking the JAVA class via the PL/SQL packages created by forms builder
8- Running the program
Thanks for your help.
Regards.

In most cases, you should not have to stop and restart OC4J_BI_FORMS to pick such changes. However, since you are having problems, I would ensure that all frmweb processes have been stopped, then stop and restart OC4J_BI_FORMS and retest. If that doesn't work, you should review how you imported the java into your app. Look closely at the Importer options you used and ensure that you have not change the file name at any point. Because you are working with Java, case sensitivity is critical.
Also, where are you seeing the error message? Client java console or in a server side log? If server side, exactly which log file is reporting the problem? I would suggest you post the first 4 ro 5 lines of the error and not just the NoClassDefFound part.

In Jython you don not need to declare the type so String userName = "HXXXXXX"; should simply read userName = "HXXXXXX" . Lots of your code need to be rewritten to work with Jython if you choose that as your technology.

Execute java code taken from a properties file

I have a requirement to store some java code in the Properties file & use the code inside the program later. Is there a way I can execute this code after I get it from the .properties file which is retrieved using the ResourceBundle?
Example:
File: system.properties
Item_list=blocksBean.menu(QueryValue,request.getContextPath())
Inside my Java program I'm using this..
theBody=codesBean.replaceAll(theBody, "%%menu%%",ResourceBundle.getBundle("system").getString("Item_list"), true);
instead of
theBody=codesBean.replaceAll(theBody, "%%menu%%",blocksBean.menu(QueryValue,request.getContextPath()), true);
This doesn't work because ResourceBundle.getBundle("... returns the value.. which is a string "blocksBean.menu(QueryValue,request.getContextPath())". But what I need is it has to be executed..
blocksBean.menu() returns a string value of html code fetched from the dartabase.
Is there a way I can execute blocksBean.menu() which is retrieved from the .properties file.. If anyone has done it / have an idea on this.. please e-mail me [email protected]
I need something like an eval() in javaScript..
Thanks in advance

Execute java code before rendering the page

Hi,
In a task flow, can I execute some java code before the page/view is rendered (i.e. some preprocessing). I would need to be able to have access to the bindings on the page.
Thanks!

Can you try doing as specified below:
If it is simple JSPX, you could use the phase listener as follows:
JSPX Code:
<f:view beforePhase="#{SamplePageBean.phaseListener}">
<af:document id="d1">
<af:form id="f1">
<af:panelFormLayout id="pfl1">
<f:facet name="footer"/>
</af:panelFormLayout>
</af:form>
</af:document>
</f:view>
Bean Code:
public class SamplePageBean {
public SamplePageBean() {
public void phaseListener(PhaseEvent phaseEvent) {
if (phaseEvent.getPhaseId().equals(phaseEvent.getPhaseId().RENDER_RESPONSE)) {
// DO NECESSARY INITIALIZATION
Thanks,

Execute Java code after login

Hi experts,
I'd like to execute some Java code after a successful login. I guess I could write a custom login module or use a WD Java iView to do this but a "better" solution may exist.
Regards,
Pierre

Customizing your login module is probably your best bet. As soon as you're user is authenticated, you can execute your custom Java code.
From my experience, I have not seen an easier / cleaner way to capture that event.

Tom

Using a button of type=button to execute java code

Hello,
I here what I need to do.
- A user fill a form
- He press submit
- the button goes and execute some java code and then refresh the page (same page)
Now I don't want to use a input=Submit, that call a a servlet that just update the information, and output to the servlet;
     out.println("<html>");
      out.println("<body>");
      out.println("<head>");
      out.println("<meta content=\"1; url=" + "SamePage.jsp" + "\" http-equiv=refresh>");
      out.println("</head>");
      out.println("</body>");
      out.println("</html>");Instead, I would like to do: <INPUT TYPE="button" VALUE="Close Window"   onClick="window.close();"> but instead of JavaScript in the onClick it would be JavaCode that would update the object (already instantiated in the JSP) and would then refresh the page.
Is this possible?
thanks.

Hi,
it is not possible because JSP code is executed server-side, while javascript code is executed client-side (in client's browser).

Class compiling/executing JAVA-Code??

Hi!
Stupid question: ;-)
Is there a possibility to "parse" Java-Code into a JAVA-Class or to give JAVA-Code to a class that compiles the code and execute it?
Thanks for answering!

background: we're running servlets and simply need to "parse" specialized/customized java-code for every customer into the servlet code. Source: database or whatever...

Batch file to execute java code

Hi,
I need to write a batch file to execute a sequence of java applications.
The problem i face is in addition to the usual libraries I am also using certain jar files i downloaded like the mail interface etc.
When i just compile a java code using a simple batch file giving the path of the compiler and the java code, it fails citing not knowing the location if the packages.
could anyone please let me know what i need to do. Is there like a skeleton that i might find somewhere for this operation

Why do you need the location of your compiler? Are you compiling or running? If you are compiling go look at Ant.

There should be a lesson about this somewhere.
When you visit a web page, does it ask you if you want to have an applet loaded?
Answer: No
So, if you visit a page, and an applet is silently loaded which can then execute commands on your computer, is this good?
Answer: No
So why do you want to do this?
Is it good for anyone?
I mean, if I want to do "ls", can't I just open a command line? Do I need an applet to do it for me?
Either you have devious desires or your hacking together something that probably shouldn't be.
