that error ur getting where a post of large files fail is definitely a WebSphere 4.0 bug. It can be fixed if u apply WebSphere version 4.0 Fix Pack 2 which upgrades it to 4.0.2 or Fix Pack 3 which upgrades it to 4.0.3. I have been trying to fix that problem since days. Let me know if it worked for you. Actually it did work for me but some other issues have come up.
The following is the problem am having right now. I would greatly appreciate it if you can help me with it.
i installed this patch called was40_ae_ptf_2_SUN.tar. Everything was installed with 0 errors. But when i try to access my applications by giving just the server name followed by the Application's Web modules context root name, i get a page not found error HTTP 404. For example if i type the follwoing in the URL --http://trypdmweb.meritorauto.com/pdmportal/
i get that error. But when i specify the jsp page after the path the page shows up. For example http://trypdmweb.meritorauto.com/pdmportal/index.jsp?
And also none of the images show up on my jsp page anymore. Can anyone please tell me what went wrong inthe upgrade. I had tried this earlier and it didnt work, so i uninstalled the patch. I tried it again thinking that it was to do somehting with the path, but it didnt' work either.
