Log4j 2 doesn’t support the Log4j v1 “.properties” format anymore (yet, since v2.4, Log4j supports a Property format, but its syntax is totally different from v1 format). New formats are XML, JSON, and YAML, see the documentation (note: if you used one of these formats in a file called “.properties”, it may be confusing). To … Read more
All database statements are executed within the context of a physical transaction, even when we don’t explicitly declare transaction boundaries (BEGIN/COMMIT/ROLLBACK). If you don’t declare the transaction boundaries, then each statement will have to be executed in a separate transaction. This may even lead to opening and closing one connection per statement. Declaring a service … Read more
It’s fine with Integer, but not okay with int – Java generics only work with reference types, basically 🙁 Try this – although be aware it will box everything: HashMap<String,Integer> userName2ind = new HashMap<String,Integer>(); for (int i=0; i<=players.length; i++) { userName2ind.put(orderedUserNames[i],i+1); }
Use setNodeValue. First, get a NodeList, for example: myNodeList = (NodeList) xpath.compile(“//MyXPath/text()”) .evaluate(myXmlDoc, XPathConstants.NODESET); Then set the value of e.g. the first node: myNodeList.item(0).setNodeValue(“Hi mom!”); More examples e.g. here. As mentioned in two other answers here, as well as in your previous question: technically, XPath is not a way to “update” an XML document, but … Read more
You can try this, String fileName = “\\/:*AAAAA?\”<>|3*7.pdf”; String invalidCharRemoved = fileName.replaceAll(“[\\\\/:*?\”<>|]”, “”); System.out.println(invalidCharRemoved); OUTPUT AAAAA37.pdf
Instead of exclude, you may use include. It’ll exactly what you want. Only this test will be executed. <classes> <class name=”test.IndividualMethodsTest”> <methods> <include name=”testMethod” /> </methods> </class> </classes>
As the statement executed is not actually DML (eg UPDATE, INSERT or EXECUTE), but a piece of T-SQL which contains DML, I suspect it is not treated as an update-query. Section 13.1.2.3 of the JDBC 4.1 specification states something (rather hard to interpret btw): When the method execute returns true, the method getResultSet is called … Read more
They are being divided in integer arithmetics. So dividing integer a by integer b you get how many times b fits into a. Also a % b will give you a remainder of a division. So (a / b ) * b + a % b = a
Save the coding, just don’t allow null values in the database. Make the default value zero. As for new BigDecimal(0): no, use BigDecimal.ZERO.
You can do the following: To store a new cookie: @GET @Path(“/login”) @Produces(MediaType.TEXT_PLAIN) public Response login() { NewCookie cookie = new NewCookie(“name”, “123”); return Response.ok(“OK”).cookie(cookie).build(); } To retrieve the cookie (javax.ws.rs.core.Cookie): @GET @Path(“/foo”) @Produces(MediaType.TEXT_PLAIN) public Response foo(@CookieParam(“name”) Cookie cookie) { if (cookie == null) { return Response.serverError().entity(“ERROR”).build(); } else { return Response.ok(cookie.getValue()).build(); } } However, … Read more
