I had several test instances already set up in SQL developer. Accidentally I deleted the jre folder in sqldeveloper folder, as well as the java jdk folders, so I was having issues accessing sql developer. I downloaded java jdk again and undeleted(retrieved) the jre folder .
When I tried to open sql developer again, it asked me to provide a jdk path, so I provided the jdk folder I downloaded, but it was giving me the error
"Unable to launch the Java Virtual Machine Located at path...."
so I searched on Stack overflow how to fix that and I found the file product.conf in folder
C:\Users\username\AppData\Roaming\sqldeveloper\19.1.0
in that file, I commented out the SetJavaHome part (as it seems the jdk path I had given was wrong). So I was able to open sql developer eventually, but everything was lost, I mean, all the instances I had set up disappeared, it's like I downloaded SQL developer for the first time.
Is there a way to retrieve everything?

I installed Oracle Tools for Kepler with no problem. But when I want to create a new server and fill in the directory to the server (which is valid, C:/glassfish4/glassfish), nothing happens. I can only click 'back' or 'cancel'.

Thanks in advance

This is really a weird error/bug/whatever. I have exactly the same setup on my home workstation and it works if I choose jdk1.7.0_55 or Default JRE as JDK in the dialog. It doesn't work when I choose jre7.
You can try to select Default JRE and see if this works.
Another option is to try a clean start of Eclipse. Edit the eclipse.ini file located in your Eclipse install directory and insert -clean as first line.
If you have downloaded a multi-language version of GlassFish 4, the problem may be related to that. You then may try it with the english only version.
If this also doesn't help you can also add the server runtime manually in the folder <WORKSPACE>\.metadata\.plugins\org.eclipse.core.runtime\.settings\ in a file named org.eclipse.wst.server.core.prefs (if it doesn't exist, create it). It should look similar to this:
eclipse.preferences.version=1
module-start-timeout=300000
runtimes=<?xml version\="1.0" encoding\="UTF-8" standalone\="no"?>\r\n<runtimes>\r\n <runtime id\="GlassFish 4.0" location\="C\:/glassfish4/glassfish" name\="GlassFish 4.0" runtime-type-id\="org.glassfish.jst.server.runtime.glassfish4" server_definition_id\="org.glassfish.jst.server.runtime.glassfish4" timestamp\="0" vm-install-id\="1399586723676" vm-install-type-id\="org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType">\r\n <map key\="generic_server_instance_properties" sunappserver.rootdirectory\="C\:/glassfish4/glassfish" sunappserver.runtimeName\="GlassFish 4.0"/>\r\n </runtime>\r\n</runtimes>\r\n
(The format looks a bit weird with the \r\n but this should be correct.)
You have to change the vm-install-id in this configuration, look for the ID of your JDK in the file <WORKSPACE>\.metadata\.plugins\org.eclipse.core.runtime\.settings\org.eclipse.jdt.launching.prefs. There should be an entry with your JDK. Copy the vm-install-id from this entry.
Make sure to have the right path to your GlassFish installation in that file.
After saving the file, start Eclipse and try to create a new server. The runtime should then be available when you choose GlassFish 4.0.

How to run eclipse in clean mode? and what happens if we do so?
I decided to turn over a new leaf and start learning Java, but after downloading eclipse I cannot seem to make it run. I originally got an error saying it couldn't find my VM so I changed the path in the eclipse.ini to where "Java Mission Control" is installed, and now it's giving me this error when I try to run the application. I have looked at many other posts where people get the same error message but they all have to do with wrongly unzipped files and I am quite sure I unzipped it properly. I have also tried different mirrors and redownloaded eclipse 5 or 6 times as well as reinstalled JDK with no avail. I have used WinZip, Windows file explorer, and Jzip all to unzip the file with the same message.
Windows 7 64bit
8gb ram,i7, 660ti graphics
If you copy and paste all of the contents into a folder on your desktop, you can then use the eclipse.exe file just fine.
I had the same problem with Eclipse. I even had a very similar problem when trying to install the Android Studio (I wanted to compare Eclipse and Android Studio). The difference with Android Studio was the error message (forgot exactly, but was saying that I was missing a .dll file that was important).
The simple thing that solved the problem:
I moved the original .zip file out of the folder where the unzipped files were created (I moved to the desktop). You can even delete it definitely because once unzipped we don't need it anymore. Then, the Eclipse.exe run smoothly (even before running it I noticed its icon changed after I eliminated the .zip). Then I went and did the same for Android Studio, run the corresponding .exe file, and tara-raaaan: run too!!!
Easy... but not obvious at all, I know. Hope this helps!
PD: Before this problem I had another one. It was related with Java (JDK); I had to add the path where it was installed and that solved the problem.
Okay, so i wiped my PC clean today. Upon attempting to install Eclipse and the JDK i hit a snag.
I install the "ADT Bundle" from android developers.
I install the JDK to the default path
When i try to open Eclipse, it cannot find my JRE (which from what i understand comes in the JDK which i downloaded from the oracle website). I know it is properly installed because i can navigate to the install path and run java programs using the exe.
iv heard something about modifying environment variables to get it to find it but nothing has worked... i dont have a "PATH" variable listed.... i do have a "Path"... but changing either one does nothing to fix the problem... I have done this installation many times and it SHOULD be working...
any help on the subject would be greatly appreciated.
Since you wiped it clean, have you tried downloading Java Runtime Environment again (maybe you wiped it too)
The solution to this problem is such:
The "Path" enviroment variable needs to be under -user variables- NOT system variables
make a new user variable named "Path" and set the value to the absolute path of the java compiler
for me it was something like C:\Program File\Java\JDK1.7\bin
that should fix the problem of eclipse not finding the JDK/JRE...
if it complains about "JNI" then you need to make sure you are running the JDK and eclipse as the same achitechture (64bit java wont work with 32bit eclipse)
The "Path" environment variable needs to be defined or updated. If you are working in Windows 8 then you can navigate by following these steps:
Open > File Explorer
Right Click "Computer"
Select "Properties"
On the left hand side select "advanced system settings"
Under the "Advanced" tab, select "Environment Variables"
Locate the Path directory in the list under System
Edit the directory by entering a semi-colon after the last entry and then manually typing the location of your Java directory.
After the full address is entered, (Should look similar to --> C:\Program File\Java\JDK1.7\bin) click "Ok" on the screen to save your changes.
Something to keep in mind while updating your path. Make sure that you direct the path to the compatible version. If you downloaded the 64 bit eclipse, choose the 64 bit Java. If you do not remember the Eclipse version you downloaded, check your download file name against the files offered on Eclipse's website. If you follow these steps Eclipse should open up without a problem.
I'm having a weird problem saving with Eclipse and MySQL Workbench. I am using Eclipse Java EE Indigo Service Release 1 and Workbench CE 5.2.24. My java is version 1.7.0_01. I am running on a Windows 7-64 machine.
I have some files on a network drive. If I edit one in Eclipse and try to save it, I get "Save could not be completed" with the reason "The system cannot find the path specified". Eclipse can successfully edit other files on the same drive. Also, another version of Eclipse on a different machine (32 bit Java EE Indigo) can edit and save the exact same file that the Eclipse on my laptop cannot save.
If I edit a model using Workbench on the network drive, I can modify the model just fine. If I try to export the script however, I get the error "Could not save file ". Failed to create file .KWLQCW". No such file or directory. I am trying to overwrite an existing script when I do the export. Again, using Workbench (same version) from another machine can make the modification that the Workbench on my laptop fails to.
I can edit or change both of these files using other editors with no problem. In fact, when I change do change them, Eclipse requires me to refresh them, but then can't save after editing them.
Both Eclipse and Workbench work just fine if the files are on my C drive. All of this was working last week and I cannot think of a configuration change I have made to my machine. I'd be grateful for any advice on debugging this.
I'd suggest you to try with the most recent MySQL Workbench version (5.2.39). The 5.2.24 version you are using is quite old. You can download Workbench here.
Well, I seem to have solved this by deleting the parent directory, recreating, and repopulating it. I can only imagine that the file system got corrupted somehow.
By changing the permission of the file and directory , the issue got resolved
As an FYI, I'm new to this entire stack, so I might be making a basic error.
I'm attempting to explore BIRT reporting for a Maximo system that was recently upgraded.
To do so, I installed the following:
Java 6 & Java 7 JDKs
BIRT version of Eclipse (Eclipse + BIRT plugins built in).
Some Oracle 11gR2 client options (a custom install)
SQL*Plus
JDBC/ODBC drivers
Thin Client
I take the following steps:
Open Eclipse
Create a new Reporting Project
Add a Data Source
Select "JDBC Data Source" (also tried "JDBC Database Connection for Query Builder")
Select the "Oracle" connection profile type and click next.
At this point, I see that the drivers list is empty. This strikes me as odd, but I figure maybe I have to define the driver definition. So I take the following steps:
Click "Define driver definition"
In the Name/Type tab, select "Oracle Thin Driver", system version 11
At this point, I see an error message: Unable to locate JAR/zip in file system as specified by the driver definition: ojdbc14.jar. It seems that ojdbc14.jar doesn't even exist on my system that I can find.
I have tried adding other jdbc jar files that I can find in the oracle client directory (i.e. from Oracle_Base\product\11.2.0\client_1\jdbc\lib) but nothing seems to resolve the issue.
Help?
I had similar issue.
Clicking "Clear all" and then adding the jar manually solved the problem.
The answer in this case was unfortunately stupidly simple -- after closing and reopening Eclipse, I had no trouble removing the driver, adding another, and getting to work. I was up and running in no time.
Thanks for all your help!
Ensure the ojdbc14.jar file exsists and is in your library path. When on the dialog for picking the driver ojdbc14.jar, simply click the find jar/zip button and find the file.
Sometimes it is there, but still does not work. To solve this problem, press the "clear all" button. Now repeat the above process. The .jar will be added and you will continue to driver connection and details dialog box.
This happens because the Eclipse IDE could not find the driver in the eclipse installation path. This is what you will do:
Search for the .jar file in your system and copy it to the eclipse installation path.
If you could not get it visit http://dev.mysql.com/downloads/connector/j and locate the required connector. Download it and save it to the eclipse installation path. So now Eclipse can see it and the error would no longer appear.
Very simple answer is Into the Jar Console Click on edit jar and Again select jar in your file system. that will locate file in your file system simple
