If you receive an error message like this when you’re opening JDeveloper, here’s the fix for it.
Error message: Unable to Create an Instance of the Java Virtual Machine Located at Path ..\..\jdk\jre\bin\client\jvm.dll
Solution 1: Copy jvm.dll file in jdk/jre/bin/client and paste to jdk/jre/bin/ojvm. Since ojvm folder has a file of the same name, make a backup of it first before you paste it so that you can revert back just in case it doesn’t work.
Solution 2: Go to Control Panel -> System -> Advanced -> Environment Variables and click ‘New’ on System variables.
Variable name: JRE_HOME
Variable value: C:\Program Files\Java\jre6
I tried this to no avail. However, I found a reference on another site saying this error will occur if Xmx is set to 1024 instead of the default 512m in jdev.conf. I changed this back and it started up using jvm6

Tq .. It worked for me
Thanks Jon, this resolved my issue as well
I have read a lot of forums in order to get the solution of this problem, and the solution for me was to Update my 7th version of Internet Explorer to the 8th one. Hope this help..
Solution that helped me:
/jdev/bin/ide.conf
In this file, change this line :
AddVMOption -Xmx800M
by
AddVMOption -Xmx512M
tnx anton.,.it worked
Still i am facing the same problem even after tried all the above solutions, please help me.

I resolved the problem by decreasing the heap size from 512M to 128M, i got the solution from other site.
Thanks
Raghuram
Thanks, I solved it too in the same way as you: decreasing the heap size from 512M to 128M.
BEFORE: AddVMOption -XX:MaxPermSize=256M
AFTER (NOW): AddVMOption -XX:MaxPermSize=128M
It worked for me too, thanks a lot!
Thanks Raghuram, Even I tried everything and only your option of reducing the Heap to 128 worked for me..
Thanks
for me there was an
AddVMOption -Xmx768M
directive in \jdev\bin\jdev.conf
that I changed to the following (as suggested by the comment above the line):
#
# Set the maximum heap to 512M
#
AddVMOption -Xmx512M
Hi,
I had the same problem on windows XP with sql developer v3.1.07.42
Here’s what I did to solve my problem :
in “C:\Program Files\sqldeveloper\ide\bin\ide.conf” :
#AddVMOption -Xmx640M
AddVMOption -Xmx512M
On WinXP SP3 32-bit / jdk6u32 / JDeveloper 11g R2, adding the AddVMOption -Xmx512M to jdev\bin\jdev.conf worked for me.
Thank you Anton your solution worked
