Re: Programmers help me With This Problem Pls !!!!!!!!!!! by Craigston: 7:08pm On Jun 03, 2015 |
You're having a problem of missing files needed by the application. I believe you downloaded Eclipse IDE as a .zip archive, unzipped it and copied the files to your system. Maybe you didn't copy all the files (they're important--all of them). Maybe you copied only the executable file? Just copy the original .zip archive to your computer, extract it into a separate folder and leave it that way (you may delete the .zip archive when you're done) and create a shortcut to the Eclipse executable file. 1 Like |

I'm not 100% sure of your woes, because I have not messed around with Eclipse IDE much for Java. I will soon though just currently don't have time. But check this out, http://web.stanford.edu/class/cs106a/lecture-videos.shtml |

Craigston: Thanks Craigston, I'll allow you to handle this. |
Re: Programmers help me With This Problem Pls !!!!!!!!!!! by Craigston: 10:35pm On Jun 03, 2015 |
Fulaman198:Thanks too. It seems it's not a Java problem. I've had this problem before. |

Usually it's because your Eclipse IDE cannot find JAVAHOME environment variable in your environment variables if you did what Craigston suggested and the problem persist. Right click on 'Computer' after clicking on the ' Start menu icon'. Click on Manage. Click on Environment Variables from the corresponding popup. Edit the environment variable and append a semi colon ';' without the quotes followed by the path to the jdk8 and jre8 folder. Note that as of Java8, jre comes bundled with java, so need to download it except for older versions. That's it and it should work perfectly. 1 Like |

Adesege: Explain well because his own failed . How do I do it |

Hey sup, been busy. Will reply you as soon as possible. chiemmaxy2: |
Re: Programmers help me With This Problem Pls !!!!!!!!!!! by Adesege(m): 11:39am On Jun 05, 2015 |
Oops! I wasn't with my system when i posted my initial reply. Just realized clicking on Manage will take you to some advanced system setup. I hope you understand this better. Right click on the 'Computer' icon either from your desktop or from start menu. Click on properties. From the corresponding popup click on 'Advanced System Settings' and allow access as an administrator. Usually, the 'Advanced' tab will be on display by default. If not click on 'Advanced'. Scroll to the last button and click on 'Environment Variables'. From the corresponding dialog, the section is devided into two; 'User Variables for {system_name}' and 'System Variables'. Where {system_name} is the name of your PC or maybe user. We are only concerned with System variables. Look for the 'path' variable. Double click on it. From the corresponding dialog, you will see two form inputs; variable name and variable value. Note that we are to append to the variable value. That's, move your cursor to the last part of the text. Type a semi colon ';' then followed by the path to your jdk bin folder. Usually C:\Program Files\Java\jdk1.8.0_45\bin. In my case 1.8.0_45 is the version number. It may differ in your case though i use Java 8 also. Like i earlier stated, Java 8 comes bundled with JRE. We need to also provide the path in our system variable before Eclipse can function. After you must have appended the jdk bin path to our system variable, we must follow it by another semi colon ';' then the path to our JRE bin folder. Usually C:\Program Files\Java\jre1.8.0_45\bin. In my case 1.8.0_45 is the version number. It may differ in your case though i use Java 8 also. Click on OK, then restart your Eclipse IDE. It's not neccessary to restart your system but you may wish to. Basically, what you'll append will look like ;C:\Program Files\Java\jdk1.8.0_45\bin;C:\Program Files\Java\jre1.8.0_45\bin Please take note of the semi colon before the initial path. Let me know if you have any problem with it. |

Adesege: Yep I did as u advised now it develop anoda problem that no java virtual machine in my path I have edited and edited and keep editing even change location of java but eclipse still tell me dy same thing dat no virtual machine found What do u think its d problem Thanks |
Re: Programmers help me With This Problem Pls !!!!!!!!!!! by chiemmaxy2(m): 5:57pm On Jun 05, 2015 |
Like this no java virtual machine found after seaching c:/proramfiles/jre/bin/javaw.exe The slash it d oda way round as u advised . Am just using phone |
Re: Programmers help me With This Problem Pls !!!!!!!!!!! by Adesege(m): 5:58pm On Jun 05, 2015 |
That means your jre path is not valid. JRE contains the java virtual machine. Did you append a semi colon before the jre path? chiemmaxy2: |
Re: Programmers help me With This Problem Pls !!!!!!!!!!! by Adesege(m): 5:59pm On Jun 05, 2015 |

Re: Programmers help me With This Problem Pls !!!!!!!!!!! by Adesege(m): 6:07pm On Jun 05, 2015 |
If that be the case, open file explorer, navigate to Program Files in your C drive. Look for Java folder. Tell me the name of the folder(s) there. Is it one or more? chiemmaxy2: |
Re: Programmers help me With This Problem Pls !!!!!!!!!!! by Adesege(m): 6:10pm On Jun 05, 2015 |
If you are on 64 bit. Follow the above step but if you didn't find the Java folder there. Go to Program Files (x86) in your C drive and look for Java folder. If it's there, open it and tell me the name of the folder(s) there. |
Re: Programmers help me With This Problem Pls !!!!!!!!!!! by chiemmaxy2(m): 6:13pm On Jun 05, 2015 |
Adesege:3 Jdk1.8.0_ 45 Jre6.0_01 Jre8.0_45 |
Re: Programmers help me With This Problem Pls !!!!!!!!!!! by chiemmaxy2(m): 6:14pm On Jun 05, 2015 |
Yep done I am on 64 bit forgive d double message |
Re: Programmers help me With This Problem Pls !!!!!!!!!!! by chiemmaxy2(m): 6:22pm On Jun 05, 2015 |
chiemmaxy2:Pls help me |
Re: Programmers help me With This Problem Pls !!!!!!!!!!! by Adesege(m): 6:25pm On Jun 05, 2015 |
That's where you got the error. In your 'path' variable in your Environment Variables, change the bin path to JRE1.8.0_45 to the one in your system. For error proof, navigate to jre8.0_45/bin. Remember, you must be in the bin folder of the jre8.0_45 folder. Now go to the top, usually the address bar of your file explorer, you will see the absolute path to the bin folder. Copy it and go to your environment variables, replace the former (jre1.8.0_45) with the one you copy. Not just the version but the full path. Hope it helps. chiemmaxy2: |

Thanks for ur help am grateful |
Re: Programmers help me With This Problem Pls !!!!!!!!!!! by Adesege(m): 7:03pm On Jun 05, 2015 |
You should know that Java is consistent. You cant use older versions with newer versions. Hope it works now? chiemmaxy2: |
Re: Programmers help me With This Problem Pls !!!!!!!!!!! by Adesege(m): 7:05pm On Jun 05, 2015 |
Don't mention. It's my pleasure.

Re: Programmers help me With This Problem Pls !!!!!!!!!!! by chiemmaxy2(m): 7:13pm On Jun 05, 2015 |
Adesege:Its netbean a good alternative what do u think hope I wouldn't encouter problems |
Re: Programmers help me With This Problem Pls !!!!!!!!!!! by Adesege(m): 8:13pm On Jun 05, 2015 |
The two IDE's are different. From my knowledge, Netbean comes bundled with Swing while Eclipse by default uses SWT. So it depends on what you want and need. Though, you can install SWT as a pluging into Netbean and Swing into Eclipse. I've not tried Netbeans anyway chiemmaxy2: |
Re: Programmers help me With This Problem Pls !!!!!!!!!!! by Craigston: 10:46pm On Jun 05, 2015 |
Netbeans allows you to point to your jdk during installation: it'll save you some stress there. I like the two IDEs. PS: has anyone tried Visual Studio? I'm thinking of that. |
Re: Programmers help me With This Problem Pls !!!!!!!!!!! by chiemmaxy2(m): 12:30am On Jun 06, 2015 |
Craigston:Does visiual studio runs java codes?? |
Re: Programmers help me With This Problem Pls !!!!!!!!!!! by Adesege(m): 2:37am On Jun 06, 2015 |
+1 there. Netbeans developers are what i call the Adobe Inc in the making. Why i said that is cos of their well structured interface, easy accessiblity and how intuitive the IDE is. Though in every aspect, their PHP Editor is next to nothing beside a Dreamweaver CC but i think their Java IDE will or maybe should be superior to Eclipse IDE. Craigston: |
Re: Programmers help me With This Problem Pls !!!!!!!!!!! by Craigston: 11:19am On Jun 06, 2015 |
chiemmaxy2:I've not seen Java in visual studio. It runs c++, c#, javascript and some other languages. Adesege:Netbeans is yet to get it right with PHP. I hope they do so. 1 Like |
