Oracle SQL Developer uses a configuration file named products.conf which is situated at your roaming directory.

If you are using Windows 7 then the directory path will be:
C:\Users\\AppData\Roaming\sqldeveloper\1.0.0.0.0

<ol>
<li>Delete whole sqldeveloper directory from C:\Users\\AppData\Roaming\</li>
<li>Re run sqldeveloper executable, this will prompt for jdk home</li>
<li>Select jdk home. i.e C:\Program Files\Java\jdk1.7.0_55</li>
<li>Enjoy!</li>
</ol>

In my case i had 2 folders under <code>C:\Users\username\AppData\Roaming\</code>

after removing both of them and launching installation <code>dir\sqldeveloper\sqldeveloper\bin\sqldeveloper64.exe</code> it worked.

blocks|key|2088092|text|我也遇到过这个问题！您应该转到:C：\Users-您的用户名-\AppData\Roaming\sqldeveloper-您的sql+developer版本-那里有一个名为product.conf的文件。右击它，在文档中用记事本编辑它，更改java+home的地址并保存它。完成了！|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2088093|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I had this problem too!
you should go to: C:\Users-your user name-\AppData\Roaming\sqldeveloper-version of your sql developer-
there is a file named product.conf there. Right click on it and edit it with notepad in the document change the address of java home and save it.
Done!

<blockquote>
 I am running Oracle 11g version of SQLDeveloper. I have same problem
 noted above, after fresh install of Oracle. The summary is that
 SQLDeveloper seems to require the Java 32-bit JDK.
 
 Install 32-bit jdk V7 from Oracle:

 There is a sqldeveloper.conf file located in 
 C:\app\UserName\product\11.2.0\dbhome_1\sqldeveloper\sqldeveloper\bin
 
 In the file change pathname within the line at end of file:
 SetJavaHome C:\app\admin\product\11.2.0\client_1\jdk 
 
 To point to pathname of the jdk install directory; also sometimes
 known as JAVA_HOME.
</blockquote>

blocks|key|4198733|text|在我的例子中，其他的建议都不起作用。相反，我将安装目录从|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4198734|c:\sqldeveloper|code-block|syntax|javascript|4198735|至|4198736|anything+else|4198737|事情又开始运转了。也许，某些Windows注册表值以无法修复的方式损坏...|4198738|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

In my case, none of the other suggestions worked. Instead, I moved the installation directory from

<pre><code>c:\sqldeveloper
</code></pre>

to

<pre><code>anything else
</code></pre>

And things worked again. Perhaps, some Windows registry value got broken in an unfixable way...

blocks|key|2087978|text|我不认为SQLDeveloper使用了环境变量。应该有一个.conf文件，其中包含对JDK目录的引用。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2087979|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I don't think SQLDeveloper uses the environment variable. There should be a .conf file that contains a reference to the JDK directory.

blocks|key|5616380|text|我通过删除文件夹/home/USERNAME/.sqldeveloper解决了这个问题。在那之后，我启动了SQLDeveloper，没有键入任何内容，它就找到了正确的java版本，并且启动时没有出现任何问题:-)|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5616381|因此，如果您不想删除整个文件夹，可以在其中搜索定义java-version+:-)的文件。|5616382|编辑:刚发现：“输入J2SE安装的完整路径名(或按Ctrl键退出)，该路径将存储在~/.sqldeveloper/jdk中”|5616383|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

I solved this by deleting the folder /home/USERNAME/.sqldeveloper
After that, I started SQLDeveloper and without typing anything, it found the right java-version and started without complaining :-)

So, if you don't want to delete the whole folder, maybe search there for the file which defines the java-version :-)

edit: just found that: 
"Type the full pathname of a J2SE installation (or Ctrl-C to quit), the path
will be stored in ~/.sqldeveloper/jdk"

blocks|key|2088080|text|检查您正在安装的java的版本Pc错误显示您正在使用4，因此卸载java，然后安装一个版本高于5的新版本|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2088081|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

check the version of java that you are installing to you Pc the error show that you are using 4 so uninstall the java that you have then install a new one that is version higher than 5

blocks|key|5616551|text|从注册表中删除实例对我来说很有效。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5616552|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Removing the instances from the registry worked for me.

When i try to start SQLDeveloper, it is giving me the following error in command prompt:

<pre><code>Error: This product requires a Java(TM) Platform 5.0 runtime.
You are using 1.4.2-b28 from C:\j2sdk1.4.2\jre
</code></pre>

But my JAVA_HOME is set to java 6

<pre><code>JAVA_HOME=C:\Program Files\Java\jdk1.6.0_32
</code></pre>

Can anyone explain what exactly to do to resolve this?
