Hi Vineel,

Please make sure you have tools.jar in your classpath.

[vineel kumar]

hi you mean classpath of the jdk tool.jar.if so i had tried that also seeting in the classpath of environmental variables it says the same error.

[Shailesh Kini]

Hi Vineel,

You have to look at the startup parameters of your app server. Your app server is looking for a JDK but probably is just using your public jre to run. The error is caused when your app server is trying to compile some files it generates during deployment. It is complaining because it does not find "com.sun.tools.javac.Main" class which is required for on the fly compilation and you should find it under tools.jar. You might just want to put tools.jar into the lib folder of your appserver. I believe that should hopefully resolve this issue.

hi
you had said to keep tools.jar file in to the lib folder of Application server.But i could not understand where it should be placed.please tell me correct destination where the tools.jar has to be placed.like from where i have to copy tools.jar and where i have to paste it.please tell me in detail.lam using weblogic8.1 server. As i had never done any installation, i don't know all these to do.Even it is a simple one i could not understand.please help me in this

Why dont you check your classpath variable from your code and check if tools.jar is in the classpath or not..

Put this in the method in your bean and see the output on the console

Map env = System.getenv();
for (Iterator it=env.entrySet().iterator(); it.hasNext(); ) {
Map.Entry entry = (Map.Entry)it.next();
System.out.println(entry.getKey() + " = " + entry.getValue());
