I am developing a tool. I use Java and Javascript in that tool.  I am calling
JavaScript function in Java file using JSObject ( win.eval() ) method.  In my
Java file I am using applet.  In Java Applet, I have a Run button. When I click
the Run button then JavaScript function should get executed. but nothin happens
and mozill a is freez.  This only happen in LINUX it works PERFECT on win2k. It
would very helpful if anyone can help me with that. I am using Mozilla 1.3 and

JSObject.eval should work fine with JRE 1.4 on Linux.

Reporter, you may need to put a simplified testcase here to let us identify the
problem.

I'm looking for a another bug which describes this, but my findings have been
that LiveConnect (JSObject, et al) are broken in 1.4.2_03 (or whatever the
current release is), but worked OK in 1.4.2 betas.  (I think it was also broken
in 1.4.2_02).

I've been running these against mozilla 1.5, and firebird 0.7.

Currently, I've downgraded to j2sdk-1.4.2-rc1-linux-i586-gcc3.2.bin from
blackdown (because I can't figure out how to get the older versions from sun).

Sorry for the premature bugspam.

The previous message may be invalid:  After reading through more java bugs, I
thought that 1.5 (j2sdk-1_5_0-beta-bin-b31-linux-i586-11_dec_2003.bin) might fix
the problem, but it didn't.

When it did not, I turned on more debugging in the java console, and found the
applet was not even loading.  Changing the applet tag from specifying "width=0
height=0" to small positive integers caused the applet to load, and liveconnect
to more or less work.  I expect that the same may work for 1.4.2_03, etc.

I wonder if it's a bug that applets don't load when they are set to zero
height/width..  (it's certainly new behavior).

JSObject works fine for me. Feel free to reopen it if you are still seeing the
*similar* problem.
