I use the class javax.tools.JavaCompiler (jdk6) to compile a dynamic source file, but the source file depends on some jar file.how should i do it.

here is my code

File sourceFile = new File("d:\\Sample\\src\\com\\pilr\\utils\\JavaBuilder.java"); JavaCompiler compiler = ToolProvider.getSystemJavaCompiler(); int compilationResult=compiler.run(null, null, null, sourceFile.getPath()); if(compilationResult == 0){ System.out.println("Compilation is successful"); }else{ System.out.println("Compilation Failed"); }

here the code shows compile time errors for import files.


How to add jar files to compile my java file

lines 5 and 6 accept only PrintStream object.

Hi ,


I am working on ANT.my requirement is to display Ant output on HTML/Jsp page.

normally i am using Ant project to execute the build file.

here is the code-my program runs and shows ant build results/errors in the console,but i want them to be stored on a string and then use that in jsp page.

File buildFile = new File("D:\\build.xml"); Project p = new Project(); p.setUserProperty("ant.file", buildFile.getAbsolutePath()); DefaultLogger consoleLogger = new DefaultLogger(); consoleLogger.setErrorPrintStream(System.err); consoleLogger.setOutputPrintStream(System.out); consoleLogger.setMessageOutputLevel(Project.MSG_INFO); p.addBuildListener(consoleLogger); try { p.fireBuildStarted(); p.init(); ProjectHelper helper = ProjectHelper.getProjectHelper(); p.addReference("ant.projectHelper", helper); helper.parse(p, buildFile); p.executeTarget(p.getDefaultTarget()); p.fireBuildFinished(null); } catch (BuildException e) { p.fireBuildFinished(e); }

help me

Thanks

hi,

i am using file upload interceptor for file uploads.
If i mention a static path the file is getting stored in that location. if i mention the path using context.getRealPath("/"); it is storing in eclipse workshop internal .
folders.The Eclipse workspace is in D: folder. My application name is Struts2proj and the actual file should be stored in Struts2proj/Images.
but when i print the filepath it is showing in this way " D:\Workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\Struts2proj\Images"

here is the code

help me out

Thanks

private Type data;

here is

public class GenericComposite implements Composite{ /** Returns the name of the type (used in XML encoding and profile checking) */ public String getName() { return "UNKNOWN"; } /** * {@inheritDoc } */ public void clear() { for (Type next : components) { next.clear(); } } }

its shows an error java.lang.ClassCastException: GenericComposite cannot be cast
to CWE

Returns the data contained by this instance of Varies. Returns a GenericPrimitive unless setData() has been called.

Hi ,

i am working on this code.

how to achieve runtime casting for the following code
public interface Type extends Serializable{ void clear(); public String getName(); } public interface Composite extends Type{ public Type[] getComponents(); public Type getComponent(int number); } public class Varies extends Object implements Type{ /** * Returns the data contained by this instance of Varies. */ public Type getData() { return this.data; } } public class CWE implements Composite{ public String getAlternateText(){ Srtirng a ="NEW"; return a; } public Sting getText(){ Srtirng b ="NEW"; return b; } }

Similarly other classes like XPN, XCN implements composite.

in the Main file the code is..
-----------------------
Varies pm=new Varies(); pm.getData(); // how to cast to CWE or XPN or XCN at runtime();

--------------------

help me...

What I am doing is capturing a biometric information ,returns a byte[] so I needed to convert it from
byte[] to a string that I could set as a url parameter and passing it as url parameter, so &m=(biometric info).

in the receiving servlet , i am able to decode to string.
my question is how how to get the actual byte array value in the servlet.

My Requirement: access session variable(a) in applet and add new variable(b) in applet then forward back to servlet and store both values in database.
