Omitting "java" from command line

How can I set up a java program so that I don't have to specify "java" at the command line. So, for example, instead of:
% java App
... I would like to type only
% App
Is there a way that's java based? What I would rather not have is some alias solution.
Thanks.

No problem - I posted the warning so that the discussion would stay in one place and we would stay sane (and calm: it's very annoying to put time into answering a post only to find the actual discussion is taking place somewhere else entirely...)

I want to launch multiple scripts written in Java from command line

Hi,
I have created a Master script file (script.java) which call functions available in other class files. (created through Java code).
Now, let's say I have 10 functions(scripts) on master script file but I want random selection for executing these functions. Do we have any interface for selection from available scripts?

"Everything I know about the command is in the man page. I can't give you a literal command, because I don't know what to put in for the arguments. To be honest, if the man page is not understandable enough for you to build the command, I don't think you should use it at all. Use Profile Manager in OS X Server, which is the right way to do what you're trying to do."
I do not know why this post did not show up here on the thread, I did get the email. Not sure how to respond. We have 800 stations. Can not go and touch each one, so looking for a command line to remove the ssid "campus" - If I read your message correct, you do not know the command line either for this. Thank you.

Java from command line, in winnt

c:>java Test
the Test.class being in c: direcctory directly
gives
ClassNotFoundException

Without the -cp option, java tries to find classes by searching the directories and jars in the Classpath environmental variable of your system. By setting the Classpath variable, you can tell java where your class files are located. You apparently have Windows, and the way to set Classpath depends on which version. You use the autoexec.bat file in Windows 98. You use the System settings from the Control Panel in Windows NT and XP. I'm not sure about others, but you can search the forum. When you set your Classpath, include . (the current directory).

also make sure that you current directory is in your classpath.
eg
export CLASSPATH=".:$CLASSPATH"
java Test
your issue is more likely to be classpath related, as java doesn't read the path variable, and the java executable is found

Error while running ADF-BC Test Suite from command line

Hi,
I have created a separate test project containing the Test Suite for the Model componenet of my ADF-BC application.
I need to run this test project separately from jmeter.
The tests run fine from Jdev, But when I package the test project into a jar and try to run from command line, I get the following error:

The Test project jar is created as ADF Library JAR File with Model.jpr as the dependent project. This takes care of project class dependencies
All the adf library dependencies are added to the manifest file of the Test Project jar referring to a location lib/ in the jar file directory.
I tried creating the ApplicationModule using both Configuration class (Configuration.createRootApplicationModule) as well as using the JDBC Connection String but both fail when I run the test cases independently from jmeter.
Anybody came across such an error? Please help.
Thanks,
Sapna

Hi Timo,
Im using JDev version 11.1.1.6.0.
I checked the class path on the jdev console. All the library references are mentioned in the manifest.mf classpath of the test project like below:
Manifest-Version: 1.0
Class-Path: lib/identitystore.jar
lib/adfm.jar
lib/groovy-all-1.6.3.jar
lib/adftransactionsdt.jar
lib/adf-dt-at-rt.jar
lib/adfdt_common.jar
lib/adflibrary.jar
lib/xmlparserv2.jar
lib/db-ca.jar
lib/jdev-cm.jar
lib/ojmisc.jar
lib/commons-el.jar
lib/jsp-el-api.jar
etc...
So I expect the library references should be resolved looking at the manifest file.
Another set of entries that I see in the jdev classpath are related to the Model project which is under test.
-classpath
D:\CurrentProject_1\16_7_2013_3pm\11_7_2013\.adf;
D:\CurrentProject_1\16_7_2013_3pm\11_7_2013\Model\classes;
How do I put these entries into my class path? Will it be sufficient if I add the Model.jar into my test project classpath?
Thanks,
Sapna

How to restore or backup Apex application from Command line ? URGENT

We have Oracle apex 4.1 installed in Oracle 11g R2 database (windows 64-bit) 2008 R2
For some reason our database dictionary objects are corrupted.
We wanted to backup our Apex applications in some workspaces ASAP.
We are not able to access apex from http://localhost:7777/pls/apex/htmldb_login
We have an underlying database schema export (expdp).
1) Is there a way to export or backup the apex application without logging into the apex URL ? if yes how ?
2) Does Oracle has any of its own native tool to backup and restore from command line ?
Thanks in advance

My (MS Windows) experience, if I may; perhaps you'll find something useful.
You'll find the README.TXT file in /apex/utilities directory. Read it.
In order to use APEXExport, you need JDK version 1.5 or higher. Check your version by typing (and viewing the result):
C:\>java –version
java version "1.6.0_06"
Java(TM) SE Runtime Environment (build 1.6.0_06-b02)
Java HotSpot(TM) Client VM (build 10.0-b22, mixed mode, sharing)Its directory should be part of the PATH environment variable: on my computer, directory name isC:\Program Files\Java\jre1.6.0_06\binFurthermore, Oracle JDBC class libraries must be part of the CLASSPATH environment variable. Check whether it exists (in Control Panel - System - Advanced - Environment Variables). For my 10gXE, it is here:C:\oraclexe\app\oracle\product\10.2.0\server\jdbc\lib\ojdbc14.jarI couldn't make it work; didn't know that ".\" directory must be entered into CLASSPATH as well (found that information in Arie Geller's book). Therefore, my final CLASSPATH version is:.\;C:\oraclexe\app\oracle\product\10.2.0\server\jdbc\lib\ojdbc14.jarOK, setup is done. Now, go to your /apex/utilities directory and, from the command prompt, run (mind the upper case!)java oracle.apex.APEXExportwhich will show a short help.
I chose to export the whole workspace. In order to do that, I need the workspace ID (got it from Apex's SQL Workshop; that might be a problem as you can't get there, can you? I can't tell how to find that information apart from SQL Workshop, but I'm pretty sure someone, who is much more experienced than me, will know it). OK, here's how you find it:select v('WORKSPACE_ID') from dual;Finally, here's the final step - export:C:\apex\utilities>java oracle.apex.APEXExport -db localhost:1521:xe -user scott -password tiger -workspaceid 1038408092496568The result are fxxx.sql files (where "xxx" represents application number).
I hope you'll manage to export your applications; basically, nothing special here (except that ".\" directory in the CLASSPATH variable).
Best of luck!

Problem with tokenized input from command line

I am trying to take an input from the command line, parse it to tokens and perform whatever operation is needed depending on the name of the token, on a binary tree of stacks for example, if i type 1 2 1 3 printLevelOrder, then the root of the tree should have 3, 2,1 in the stack, the left child should have 1 and the right child should be empty. and then a level order print of the tree should be performed.
however what is happening when i run this code is the numbers are being put into the right stacks of the tree, but any commands such as printLevelOrder or PrintPopRoot are entering the code that is for placing numbers onto the stack instead of executing that command and skipping past this piece of code.
so my question is, why is the if statement if (word =="printLevelOrder") not being executed when thats whats in the word ?
example input and output shown below code fragment.
          try {
              BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
             String line = "";

                              System.out.println("(word ==printLevelOrder)");

Query runs from command line, but not from scheduler

We use Control-M to schedule shell scripts to be run on a Solaris server. Some of the scripts have to access an Oracle database and in that case our security team will include the DB user and password in the script, then encrypt it and the sys admin team schedules the encrypted shell script with Control-M. That works fine, but we've been trying to have the DB user and password on a separate encrypted file so that we don't have to ask for file encryption every time it's necessary to modify a script (this is a test environment).
We have the script at ~/system_name/scripts, the query at ~/system_name/sql and the encrypted file and key at ~/system_name/keys. The SQLPlus call in the script is:
${ORACLE_HOME}/bin/sqlplus "`decrypt -a 3des -k ./../keys/key.3des.system -i ./../keys/login.system`"@instance_name <<EOF
@${DIR_SQL}/TEST_QUERY.SQL
quit
EOF
The security analyst has tested is successfully from command line, but when we schedule it with Control-M the job abends and we get the following in the sysout:
+ decrypt -a 3des -k ./../keys/key.3des.system -i ./../keys/login.system
decrypt: cannot open ./../keys/key.3des.system
decrypt: invalid key.
+ /u00/app/oracle/product/11.1.0/db_1/bin/sqlplus @instance_name
+ 0<<
@/sistemas/hmp/system_name/sql/TEST_QUERY.SQL
quit

Any ideas?

Looks like the command is being split in some way - the connection to sqlplus is being made before it completes the whole string
It appears to be seeing the @instance_name as a script to execute rather than a db to connect to.
Is the database on the same server as the script?
If so, try setting your environment to the correct databsae, so that you can omit the @instance_name part of the syntax and see if it helps
Also just noticed the failure to open the decrypt script. It would appear uyou are not using a full path name. Have you checked which directroy the scheduled job starts in? You may need to look at running some environment specific scripts first.

Running java from command prompt?

What do I need to be able to run java code from the command prompt? I have J Builder and when I have questions, mainly people give want me to run from command line. When I do so it says it does not know what javac is.

javac, java etc.. commands are in the j2sdk\bin directory.
So you have to give PATH to that bin directory in order to use it in command line. Go to the JBuilder installation folder and look for the j2sdk. (JBuilder comes with the j2sdk but the name may vary)
If you find it, then give the PATH to it's bin directory.
Or you can download the j2sdk from sun seperately, and give the PATH to its bin directory.

How to run a Servlet Project's .war from Command Line??

Hi there,,
Can anybody help me with how to run a Servlet Project's .war file from command line??In fact I tried it using the following command,

I can't find the project''s manifest file in the META-INF folder.
Moreover,plz help me about know how to execute a single servlet class from command line...
Thanks in advance...

you cant run a .war file from command prompt
.war files should be executed in a server
how to execute a single servlet class
do you mean to run the servlet or compile the servlet?
any way you need a server and if you are a beginner Apache tocat will be the best server to start with you can down load it from

How to run Ant from command line in Tarantella env?

I am getting Exception in thread "main" java.lang.NoClassDefFoundError: org.apache.tools.ant.launch.Launcher error message when I run Ant from tarantella command line. Is this Ant version issue? I can only find Ant with version 1.4.2. Where can I find the correct Ant version (1.6.5) and what class path do I need to specify if I want to run Ant from command line. This works if I run Ant inside of Jdeveloper 11g.
thanks

Hi

JSPC Compiler gives FileNotFound Exception from command line

I have problem running jspc from command line
          From the browser, the jsp pages compile fine.
          I have tested this on NT 4.0 and on HP UX 10.0 with Weblogic Server
          4.5.1 and SP 9.
          The command I typed in as follows:
          $java weblogic.jspc -d /opt/b2berp/jspclassfiles/ - docroot
          /opt/b2berp/web -keepgenerated true -classpath
          /opt/jdk/1.2.2/lib/classes.zip:/opt/weblogic/weblogicaux.jar:/opt/b2berp/lib
          I get the following exception:
          I checked the file is in PATH and I am also specifying the absolute path
          and filename.
          My document directory is /opt/b2berp/web/auctions/
          All of my jsp pages are under /opt/b2berp/web
          This is also my web folder.
          Gives error unable to find file
          (FileNotFoundException)
          Does anyone know what is going on.

Hi,
If you are still having problems creating a domain from the command line, the official solution would be to use
{proper_path}/bea/weblogic{proper_version}/common/bin/config.sh -mode=console
This will guide you to the same steps as the visual version of the wizard, but using the command prompt.
If you are using windows, the same works but with the command config.cmd, and mutatis mutandis.

Unable to build and run Javapetstore using Sun SDK from Command Line

Hi,
Here is a problem I?ve come across building and running JavaPetstore from Command Line using Ant.
It shows that Build is successful but there is an error message in very beginning:
?Unable to locate tools. jar. Expected to find it in C:\Program Files\Java\jre 1.5.0_11\lib\tools.jar?
But there is no such a file in jre-1.5.0_11 or previous versions.
The only place where the file with such name can be found is jdk\lib.
All attempts to run end up with:
? BUILD FAILED.
C:\<PETSTORE_HOME>\bp-project\command-line-ant-task.xml:77;unable to find javac compiler;com.sun.tools.javac.Main is not on the class path.
Perhaps JAVA_HOME does not point to JDK."
Directories C:\Sun\SDK\bin and C:\Sun\SDK\jdk are in the PATH.
JAVA_HOME as a System variable is set up to C:\Sun\SDK\jdk.
Building and running other applications like a BluePrints or Samples bring to same result.
I will post more information if needed.
Thank you in advance for help.

If you are using Windows XP:
1. Right click on my computer
2. Select Properties from the popup dialog
3. Click on the "Advanced" tab
4. Click the button towards the bottom that says "Environment Variables"
5. In the dialog that pops up, look in both the User variables and the System variables for a variable named CLASSPATH
6. If its not there, you need to create it. If you want to make it available to all users of your computer, create it as a System variable. If you only want it to be available to the current user, add it as a User variable.
7. If it is there, or if you just created it, it needs to contain the following values: the current directory (symbolically abbreviated as a period: "."), any class libraries you want to be available to the java compiler (javac) or the java interpreter (java). By default, jre/lib and jre/lib/ext are searched for classes, so you don't need to include anything located in one of these folders on the classpath.
