Example 1 with ELManager

use of javax.el.ELManager in project tomcat by apache.

the class TestELParser method doTestParser.

private void doTestParser(String input, String expectedResult, String expectedBuilderOutput) throws JasperException {
    ELException elException = null;
    String elResult = null;
    // Don't try and evaluate expressions that depend on variables or functions
    if (expectedResult != null) {
        try {
            ELManager manager = new ELManager();
            ELContext context = manager.getELContext();
            ExpressionFactory factory = ELManager.getExpressionFactory();
            ValueExpression ve = factory.createValueExpression(context, input, String.class);
            elResult = ve.getValue(context).toString();
            Assert.assertEquals(expectedResult, elResult);
        } catch (ELException ele) {
            elException = ele;
        }
    }
    Nodes nodes = null;
    try {

        Assert.assertNull(elException);
    } catch (IllegalArgumentException iae) {
        Assert.assertNotNull(elResult, elException);
        // Not strictly true but enables us to report both
        iae.initCause(elException);
        throw iae;
    }
    TextBuilder textBuilder = new TextBuilder(false);
    nodes.visit(textBuilder);
    Assert.assertEquals(expectedBuilderOutput, textBuilder.getText());
