Compile source string like java code

I need to calculate some user defined formulas in my application. I have this formula in string form (e.g. "operand1 * operand2 + operand3" ). I have gained operand values throught the reflection and pars this string throught the StringTokenizer. So I have parsed string with operand values and operators. Is it possible to compile this string like java code ?
Thanks for all hints

Compile to what - a class file?
Yes, it's possible if you don't mind using non-100% pure Java. You can compile them using the sun.tools.javac.Main class found from tools.jar in the lib directory of the jdk.
But from what you say it would be easier to use an existing expression evaluator. Take a look at JEP (jep.sourceforge.net) and BeanShell (www.google.com) before you make any decision.

  • How to compile connection pool sample java code

    I recently bought David Knox's "Effective Oracle Database 10g Security by Design", and have been working through his examples with client identifiers and how to leverage database security with anonymous connection pools.
    The database side of things I totally understand and have set up, but I now want to compile/run the java code examples, but don't know what is required to compile this.
    I'm running Oracle 10.2.0.4 (64-bit) Enterprise Edition on a Linux (RHEL 5) PC. Java version is 1.6.0_20. Relevant .bash_profile environment variables are as follows:
    export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
    export CLASSPATH=$ORACLE_HOME/jre:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
    export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin
    When I try to compile, I get:

    Could not find the main class: FastConnect.java. Program will exit.
    The java source code of one of the examples is below. Is someone able to point me in the right direction as to how I get this to compile? Do I just have a syntax and/or environment configuration modification to do, or is there more to it than that to get this example working? Any help much appreciated.

    I will try to explain what is happening here.
    You are launching java telling it to run a class named 'java' in a package named 'FastConnect'
    and java says it cannot find that class.
    What you intended to do:
    $ # make the directory structure match the package structure
    $ mkdir OSBD
    $ # move the source file in the directory structure so it matches the package structure
    $ mv FastConnect.java OSBD/
    $ # compile OSBD/FastConnect.java to OSBD/FastConnect.class
    $ javac OSBD/FastConnect.java
    $ # launch java using the OSBD/FastConnect class
    $ java -cp . OSBD.FastConnectNote that the package 'OSBD' does not follow the recommended naming conventions
    you might consider changing that to 'osbd'.

  • Tools for extracting strings from java code for internationalization

    For legacy code with lots and lots of strings what method is typically used to extract strings for internationalization?
    Am I right in thinking you couldnt simply grep for strings, it could get pretty complitcated, especially with escape characters, escaped quotes etc.,
    -SK

    When dealing with legacy code, it is nice to have an application that queries you as it extracts the strings. You have a choice whether to accept the string as a localizable entity or not.
    There are several tools that do this...including some IDEs like JBuilder. Although it isn't a fully supported or robust tool, Sun has a utility for extracting strings in Java source files:

  • Using Textbox strings in Java code

    Hi,
    I wonder if anyone can help me with a problem I'm
    having with a JSP.
    I've got several text boxes on my JSP which are static and would like to access their contents from within some dynamic Java code contained within the same JSP. I.e If I have a text box whose name is my_text I
    would like to use my_text as a string within my Java code.
    Does anyone know how to do this?
    Thanks,

  • Converting String into Java code

    Hi everyone,
    I will describe the scenario I have. I have a GUI application. I want the user to write some Java code in a text box and plug that code during runtime. Is there a way in Java so that a string could be used as a Java code?
    You help is really appreciated.
    Thanks
    RG

    catch the string input
    output string (code) to file
    call javac on the file you made
    that's it, you have a class, and you can run it/load it

  • Text formatted like Java code

    I was going to put some examples of java code on a website that I'm currently building, what is the easiest way to format the HTML to look like some of the code examples used in these forums? Could I do it with a stylesheet or XML or would I have to do something really complicated?

    Just use normal html: heres a template:-
    <html>
    <title>* Your title *</title><head><h4>AProgram.java</h4><hr></head
    <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
    <body bgcolor='white'>
    <table border=0 cellPadding=2 cellSpacing=0 width="100%">
    <TR><td width="8%"></td>
    <td width=80%></td><td></td></tr>
    <tr></td><td><td><font face='Courier' size='3' color='black'>
    public class AProgram {
    </body>
    </head>
    Don't use the <pre> tag as cuases the text to be unusually spaced or to come out tiny for those using resolutions above 800 x 600 and you'll need to hand code certain things eg;-
         space = & nbsp ; // close the spaces
         left tag '<' = & lt ; // close the spaces
         right tag '>' = & gt ; // close the spaces

  • Translate the string source like java source

    Mayba possible. But why you dont convert the Strings in primitve types? You have just using static methods in the Wrapper classes like: Integer.parseInt(String), Double.parseDouble(String) and so on. The operators you can convert in a charakter and use
    switch (operatorChar):
    case '+' : ...
    case '-' : ...
    Take a look at the java.lang.Compiler, if you still want create bytecode.

  • Error while running compiled java code

    Hi
    I have an evaluation license of the JDeveloper2.0 installed on my WindowsNT 4.0 workstation.
    I seem to have a problem running my compiled jave code. After compiling the source code(.java file) when I try to run the same I get a message saying
    "<FileName> not found in outpath classpath or sourcepath ".
    What does this mean and how can I rectify it?
    Regards
    Sree
    null

    Your classpath tells Java run time where to look for the class files it needs. In JDeveloper the class path is set in your project properties. Select Project->Properties and check that the source and output paths correspond to your myprojects and myclasses directories.

  • Getting java code to compile on unix/linux

    I have been using borland JBuilder to run and compile my java code. Recently i tried moving the code to a linux machine in which i have downloaded the JDK to. My classes only use standard java classes with the exception of a jbcl.jar file which has a class that one of my classes relies on. It turns out when i try to run my class i get error messages because it cant find the jar file. Where should I put this jar file? by the way in my class i use the statement: where jbcl.layout is the class i need.
    import jbcl.layout.*;

    another question. In my class I use the statement
    import jbcl.layout.*;
    so all i need to do is add the jbcl.jar to my class
    path? is my import statement correctIf it compiles in your IDE, then it's correct. You shouldn't have to change anything at all in your source code to use a different compiler or to compile on a different platform. You just have set up the proper environment and parameters--tell it which .java files to compile, which jars or directories to search for classes in (classpath), etc. For IDEs you do that with the Preferences or Options menu item. For command line compilation you do this with command line arguments, config files (a la build.xml for ant), or environment variables (although relying on the CLASSPATH env var is generally a bad idea).

  • How to check for a logic bomb in compiled java code ?

    I have couple of security requirements.
    1. How do I check for logic bomb in the compiled java code ?
    2. Is there any way to monitor memory utilized by class when running inside a constructor ?

    1. Let me see if you can define 'logic bomb', then maybe a answer can be supplied. If you simply mean malicious code, then in general you cannot. You can attempt to do the kinds of things that antivirus software does, like check for the existence of known malicious code and code patterns, but that won't work any better on Java than it does on anything else.
    2. Google java profiling. Also, for something relatively simple, read about jconsole.

  • 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!
    Mark Hauchwitz.

    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...
    How to get started?

  • Java code in jsp source files is not allowed in ojsp.next mode.

    Hi,
    I’m working on WC Spaces Customization library “com.acme.custom.webcenter.spaces.war”. From time to time, when I deploy the library to WC Server, it errors out.
    weblogic.management.DeploymentException: Cannot undeploy library Extension-Name: com.acme.custom.webcenter.spaces, Specification-Version: 11.1.1, Implementation-Version: 11.1.1.2.113 from server WC_Spaces, because the following deployed applications reference it: webcenter-rest.war, spaces.war, sharepoint-servlet.war, webcenter-rss.war
    If I try to login the Spaces, I get “Java code in jsp source files is not allowed in ojsp.next mode.” Should I stop the Spaces server before the deployment? In this case, other people won’t have accesses to Spaces? The deployment error doesn’t happen all the time.

    I don't think that this error is based on ojsp.next mode. The first error I see is that the application can't be undeployed. After that you get the 'ava code in jsp source files is not allowed in ojsp.next mode.' error. As you said this only happens sometimes which also point to an other problem and not to the jsp error.
    Have you ask this on the {forum:id=354} forum?
    For me it's more a deployment/redeployment question.

  • How to track the information/error of java code while compiling.

    Hi,
    I want all the information or errors of java code during compilation.
    So that I can use this information or I can show these errors with different style.
    How to get the java syntax errors?

    Hi,
    I want all the information or errors of java code
    during compilation.
    So that I can use this information or I can show these
    errors with different style.
    How to get the java syntax errors?Redirect the STDOUT/STDERR from the the JAVA/JAVAC command to a file is one way...
    For instance at the commmand line:
    javac myClass.java > STDOUT.txt 2> STDERR.txt (Works for Unix variants or Windows OS's)
    Then you can do what ever you want with the data contained in the files.
    Hope this helps
