jdk1.5

I'm running this code with JDK 1.4 and 1.5 and get different results. Why is it the case? String str = ""; int test = 3; str = String.valueOf(test); System.out.println("str[" + str + "]\nequals result[" + (str == "3") + "]"); if (str == "3") { System.out.println("if"); } else { System.out.println("else"); } outputs: on jdk 1.4 str[3] equals result[true] if on jdk 1.5 str[3] equals result[false] else According to this page , the Integer#toString method (which is called by String#valueOf(int) ) is implemented like this in 1.4: public static String toString(int i) { switch(i) { case Integer.MIN

I'm trying to use JAXB to unmarshal an xml file into objects but have come across a few difficulties. The actual project has a few thousand lines in the xml file so i've reproduced the error on a smaller scale as follows: The XML file: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <catalogue title="some catalogue title" publisher="some publishing house" xmlns="x-schema:TamsDataSchema.xml"/> The XSD file for producing JAXB classes <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <xsd:element name="catalogue" type="catalogueType"/> <xsd:complexType name="catalogueType"> <xsd

I'm not sure if this question has been answered in full or if my title is descriptive enough given my situation, but I've been asked to convert a project from being built with Ant to Maven. That part isn't too bad, but I've been told that this application was designed specifically for the JRE version 1.5 rather than the JRE 6 everything else I've been dealing with uses. Now, I'm incredibly new to Eclipse and Java themselves, so I was a bit confused when I was asked to tell either Eclipse or Maven to build this particular project using the JRE 1.5 instead. I have it installed, I believe, and I

I use OS X Yosemite (10.10.2) and I have to use JDK 1.5 for legacy application development. I found this post which refers to this script to install JDK 4,5,6 in Lion and Mavericks. In comments I found this two lines /usr/libexec/PlistBuddy -c "Set :JavaVM:JVMMaximumFrameworkVersion 14.*.*" ./Resources/Info.plist /usr/libexec/PlistBuddy -c "Set :JavaVM:JVMMaximumSystemVersion "$osx_version".*" ./Resources/Info.plist have to be changed by /usr/libexec/PlistBuddy -c "Delete :JavaVM:JVMMaximumFrameworkVersion" ./Resources/Info.plist /usr/libexec/PlistBuddy -c "Delete :JavaVM

I've been trying to get this to work for a while now but no luck yet. I want to run with JAVA_HOME pointing to JDK7 but I want to compile a project for JVM 5. I've read through documentation , I've found similar posts on SO, but none of them seem to work in my setup. I first tried with setting just target and source but I got an error: <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.5</source> <target>1.5</target> </configuration> </plugin> [ClassName] is not abstract and does not override abstract method

I am testing RESTful services and when I execute I am getting exceptions although I have the following jars in my class path(WEB-INF/lib), I am not using Maven and my JDK version is 1.5. Other questions regarding this issue didn't help to resolve the problem. Code snippet @GET @Produces("application/json") //@Produces({MediaType.APPLICATION_JSON}) tried this, didn't work either public List<Emp> getEmployees() { List<Emp> empList = myDAO.getAllEmployees(); log.info("size " + empList.size()); return empList; } @XmlRootElement public class Emp { ...... web.xml <servlet> <servlet-name>Jersey Web

I'm using Java 1.5 and I'd like to launch the associated application to open the file. I know that Java 1.6 introduced the Desktop API , but I need a solution for Java 1.5 . So far I found a way to do it in Windows: Runtime.getRuntime().exec(new String[]{ "rundll32", "url.dll,FileProtocolHandler", fileName }); Is there a cross-platform way to do it? Or at least a similar solution for Linux ? OscarRyz +1 for this answer Additionally I would suggest the following implementation using polymorphism: This way you can add new platform easier by reducing coupling among classes. The Client code:
