Hi, I am new to using eclipse, just started and still exploring. I have typed a program, no errors no warnings, After I run the class file where is the output stored, I mean what should I do to see the output?

Hi,I have the classes Embed.java and watermarkdemo.java

There are some lines of code in the main method of Embed.java.
I want to call the main method of Embed.java in the actionPerformed () method when the user clicks on the insert button.
Please can someone give me the outline of how this can be done?

I hope I am clear in my problem and it is easy to understand what I am actually saying.
Thankyou

There should be some way for the user to know/check if the question he is about to post already exists.
Just for an example,suppose the user types a sentence containing the word 'getInitParameter()' ,then all the previous related questions should be loaded somewhere near the subject box.I mean what i am saying is similar to google search,when you type a word,Google loads the related as you are typing.
That would kind of be a good idea!! what say??

Actually i did not yet get the answer to my first question,if that is answered rest all is solved.Is there a way in which i can recompile all the class files of a jar file with a different version of java?Please,i really need it.

It has happened with me a few times when there was a version compatibility issue i would get the "cannot find symbol" errors and later resolved using a higher version of java,so on that basis i think it might be the same problem.
When i try to use the jar file (for my requirements in the project),the .class file is created but i get the errors cannot find symbol.

The errors are nothing related to the java file(the java is the basic hello world program),so i assume that i am getting all the"cannot find symbol" errors due to the version compatibility issue of the jar file.

Is there any solution to this problem or should i actually sit and re compile all the 50 .java files ONE BY ONE.It would really be breathtaking to do that and i dont know how much time would i actually have to spend doing it

Yes i know i gave the sollution myself but i just wanted to confirm if there is a better and faster way to do it.Because there are like 50 .java files and i cannot compile them using javac *.java as there are multiple folders in the same jar file

Hi,i got the source file that contains all the related java programs.So what should i do now? should i compile all the .java files from the zip folder and paste them in the jar file that i have??Thankyou.

Hi,i am using a jar file in a different program and when i run the program i get multiple "cannot find symbol" error.

As much as i know the errors are probably because the java version that i am using is higher than the java version with which the jar was compiled.

The jar file does not contain the source so i cannot see the java files,only the class files are there.

My question is,is there any way in which i can recompile all the .class files,with the new java version that i am using.How to do it??Hope to get some help.
Thankyou.

Hi,so after long struggle i sorted out my problem.I was previously running the matlab control jar file on my desktop which gave me the error

After a lot of google search on the error i concluded that the error was because there were multiple versions of matlab installed on my desktop.Even if you uninstall all versions and keep just one you still get the error because there are some registry keys that do not get deleted and hence leave some traces of matlab behind,you need another software if you want to entirely cleanup matlab.
So basically there was a conflict in the location path hence the matlab control jar file could not detect as to which location path it should use to launch matlab.
I actually couldn't waste much time in solving the error hence a quick fix was to use my laptop in which i had never installed matlab.Now its working perfectly and i am still working on the rest of the code that i was supposed to do.
I am deliberately posting the detailed explanation so that someone facing a similar problem as mine may end up on this page and magically find the sollution;)
Thankyou:)
