init
public void init(JspCompilationContext ctxt, ErrorDispatcher errDispatcher, boolean suppressLogging) Description copied from interface:JavaCompiler
Initializations- Specified by:
init
in interfaceJavaCompiler
-
release
public void release()Description copied from interface:JavaCompiler
Release resouces used in the current compilation- Specified by:
release
in interfaceJavaCompiler
-
setExtdirs
- Specified by:
setExtdirs
in interfaceJavaCompiler
-
setClassPath
Description copied from interface:JavaCompiler
Java Compiler options.- Specified by:
setClassPath
in interfaceJavaCompiler
-
getClassLastModified
public long getClassLastModified()Description copied from interface:JavaCompiler
Return the time the class file was generated.- Specified by:
getClassLastModified
in interfaceJavaCompiler
-
getJavaWriter
Description copied from interface:JavaCompiler
Get a Writer for the Java file. The writer is used by JSP compiler. This method allows the Java compiler control where the Java file should be generated so it knows how to handle the input for java compilation accordingly.- Specified by:
getJavaWriter
in interfaceJavaCompiler
- Throws:
JasperException
-
setDebug
public void setDebug(boolean debug) - Specified by:
setDebug
in interfaceJavaCompiler
-
setSourceVM
- Specified by:
setSourceVM
in interfaceJavaCompiler
-
setTargetVM
- Specified by:
setTargetVM
in interfaceJavaCompiler
-
saveClassFile
Description copied from interface:JavaCompiler
Save the generated class file to disk, if not already done.- Specified by:
saveClassFile
in interfaceJavaCompiler
-
doJavaFile
public void doJavaFile(boolean keep) Description copied from interface:JavaCompiler
Remove/save the generated Java File from/to disk- Specified by:
doJavaFile
in interfaceJavaCompiler
-
compile
public JavacErrorDetail[] compile(String targetClassName, Node.Nodes pageNodes) throws JasperException Description copied from interface:JavaCompiler
Start Java compilation- Specified by:
compile
in interfaceJavaCompiler
- Parameters:
targetClassName
- Name of the class under compilation- Throws:
JasperException
-
safeGetProblems
private static final org.eclipse.jdt.core.compiler.IProblem[] safeGetProblems(org.eclipse.jdt.internal.compiler.CompilationResult result) Invoke CompilationResult#getProblems safely so that it works with 3.1.1 and more recent versions of the eclipse java compiler. See https://jsp.dev.java.net/issues/show_bug.cgi?id=13- Parameters:
result
- The compilation result.- Returns:
- The same object than CompilationResult#getProblems
