sendMail service over online MS Office365
Ofbiz Users, Our office recently moved from gmail to the online MS Office 365. I'm trying to configure the ofbiz sendMail service to use the SMTP relay to route through smtp.office365.com. I've made the changes in the general.properties file but I'm still getting a client was not authenticated error. Has anyone else configured ofbiz to work with office365? Here are my configuration settings: mail.smtp.relay.host=smtp.office365.com mail.smtp.port=587 mail.smtp.starttls.enable=true mail.smtp.socketFactory.fallback=true Any information on this would be appreciated. Brett
Re: sendMail service over online MS Office365
Thanks for the reply. The settings in the thread are what I have now. These worked well with a gmail account but I haven't been able to get similar settings to work with MicroSoft's office365 product.

Re: Should we use some lock when update qoh of InventoryItem
We have run into this problem in the past with the inventory and other entities when running multiple application servers under high load. We worked around this issue by creating a custom class that gets the Connection from the entity engine. Then we built a custom JDBC query to do a SELECT for UPDATE that guarantees no other process can update the record until the transaction is committed.

Yes, the select for update approach does have a potential for locked conditions. We used it rarely and only in those situations where we had to guarantee there was one and only one record.

Problems with jackrabbit configuration and remote MySql database
I'm trying to configure jackrabbit to work with a remote mysql database. I
have changed JackRabbit to work with MySql instead of the default derby by
adding a Versioning and Workspace configuration for mysql. This same
configuration works on a local mysql database (ofbiz and mysql on same
machine), but now when I try to access the remote database I get a
connection failure.
The same mysql configuration is working for ofbiz because I can correctly
create the database tables and seed them with the following ant builds:
ant run-install
ant run-install-seed
But using the same MySql configuration attributes for host, user, and
password I get the the following error:
20411 [main] ERROR org.apache.jackrabbit.core.RepositoryImpl - Failed to
initialize workspace 'default'

I'm not using the standard 'ofbiz' database name. Would that be a possible
problem? Are there other configuration files I am missing to setup
jackrabbit? I've only edited the ofbiz/framework/jcr/config/jackrabbit.xml
file for this mysql change.
Thanks in advance for your help.

Re: Problems with jackrabbit configuration and remote MySql database
I found the error. I was using a previous copy of ofbiz from another
environment. The configuration is copied at run time to runtime/data/jcr
directory. It was picking up an old configuration. I had run clean but
this was not clearing out these directories.
I deleted the data/jcr directory and restarted the server and everything
came up all right after that.

The only place I have found this to be a problem is in the server hit entity. The server hit functionality is configurable. We disable that functionality.

Re: Ofbiz with MySQL or PostgreSQL
In the framework/webapp/config/ directory there is a serverstats.properties file that you can turn off and on stats. For example: stats.persist.REQUEST.hit=false stats.persist.EVENT.hit=false stats.persist.VIEW.hit=false stats.persist.ENTITY.hit=false stats.persist.SERVICE.hit=false The above properties will turn off persisting the stats for ofbiz which is where you get constraint errors in mysql because the server stats use a timestamp as a primary key.

Re: Ofbiz with MySQL or PostgreSQL
Sanjeev, We've used MySQL for several years now. I think most ofbiz user prefer Postgres. We like Postgres but the one feature that keeps us with MySQL is its replication feature. Replication in MySQL is very good and easy to administer. We use them for running reports which helps us scale our solution. We have a data warehouse with a fact table of over 30+ million rows and mysql does a good job with it. Brett On Thu, Jun 21, 2012 at 8:47 PM, Sanjeev Gupta subscr...@sanjeevg.comwrote: Thanks Ruth.

Re: JobManager failing to schedule jobs
wouldn't want to make it bigger than the default polling interval. Do you know what the default interval between polling is? Thanks, On Wed, Jul 13, 2011 at 12:31 PM, Brett Palmer brettgpal...@gmail.com wrote: I meant removing finished jobs. If you have thousands of pending jobs then you will have the same problem I mentioned in my first email. One resolution will be to increase the job poller transaction time. In the ofbiz version I was using there was not a way to configure the poller transaction time. It just used the default time. I had to create a patch to allow this to happen. In the patch you had to be careful to not increase the transaction time greater than the frequency of the job poller. Otherwise you get into a lock situation where one job poller is still running within a transaction and another poller starts. This didn't create a huge problem but the second job poller would usually lock and then time out. Brett On Wed, Jul 13, 2011 at 1:15 PM, Josh Jacobson josh.s.jacob...@gmail.comwrote: Brett,
Re: JobManager failing to schedule jobs
Josh, I've also seen this problem if the JobSandbox table has too many rows to process. I ran into a similar problem when I tried to run 10,000 Async batch processes. The time it took for the JobPoller to process all the records was too long and the transaction would time out. I had a patch to change the transaction timeout for the JobPoller specifically as it wasn't available in ofbiz at the time, but I don't think I ever submitted it. I could look for this patch if anyone is interested but it may already be implemented in the framework. I would try archiving jobs from the JobSandbox first.

Re: JobManager failing to schedule jobs
I meant removing finished jobs. If you have thousands of pending jobs then you will have the same problem I mentioned in my first email. One resolution will be to increase the job poller transaction time. In the ofbiz version I was using there was not a way to configure the poller transaction time. It just used the default time. I had to create a patch to allow this to happen. In the patch you had to be careful to not increase the transaction time greater than the frequency of the job poller. Otherwise you get into a lock situation where one job poller is still running within a transaction and another poller starts. This didn't create a huge problem but the second job poller would usually lock and then time out.

Re: JobManager failing to schedule jobs
Josh, I'm attaching the patch I used to work around this issue. This is based on an older version of ofbiz so I would compare your current files carefully. The following files were patched: service-config.xsd serviceengine.xml JobManager.java JobPoller.java The patch allowed for a new configuration option poll-transaction-timeout=300 I'm pretty sure that I was using 300 seconds for the poll-transaction-timeout. I believe the default is 60 or 120 seconds. I originally created a JIRA issue 3855 for this problem. https://issues.apache.org/jira/browse/OFBIZ-3855 If you set the transaction time out too high when the poller wakes up to process new requests it will timeout because the first poller has a lock on the table (or ofbiz semaphore method). Here are a couple of other options you could try since the number of pending jobs is so high. 1. Create a temporary status for the jobSandbox statusId and assign a large set of pending transactions to this status. Then only process a few 1000 at a time. Then you can incrementally change these back to pending so the service engine can process them in reasonable batches. I haven't tried this option but it would allow you to work with the service engine without modifying any code. 2. Start up several more instances of ofbiz all pointing to the same database. Each will start service process to process more requests in parallel. This probably won't work with out the patch I've attached as each service process would still time out and not allow other processes to start.

Re: Optimistic locking based on timestamps
David, I like postgres for the reason you have mentioned. The number one reason we use MySQL in some of our deployments is because its replication solution is very good. You can replicate your data from the database very quickly. We do this for database backups in production as well as creating reporting servers. I have not been able to find a good replication solution for postgres. Its been a while since I looked but the last time I investigated replication I couldn't find any.

Jacques I was hoping you would post to tell me I was wrong, and point out the locking semantics in the delegator that the application can use. My current plan is to extend the delegator and minilang so that findOne and entity-one can have a for update parameter, so that at least the application can decide to do a select for update, to introduce some locking to avoid concurrency bugs. Right now, it's fairly common to for us to issue inventory items until the quantity goes below zero, because there's no way to regulate concurrency between two threads that want to issue. There are many parts of the system where this might not be such a problem, but on InventoryItem it's a potential nightmare. What do you think about my idea of giving the delegator a select for update option? Adding a for-update option is a good idea, and is something I have incorporated into the Moqui design. As Jacques mentioned chances are you'll still have a better experience with Postgres when it comes to concurrency issues, in the way they manage transactions and locking in addition to the timestamp resolution issue. I honestly don't know why so many people like MySQL compared to Postgres, but I know that many people do. Maybe it's the greater marketing budget of corporate-driven MySQL versus the more community-driven Postgres. It's also a shame that when SAP DB was scavenged for useful things to go into MySQL that it wasn't done the other way around, ie take useful things from MySQL and put them into SAP DB. Of course, I haven't looked into the state of either code base before this was done, but I do know which organization acquired the other and that probably drove the direction for the software (it's bad marketing to come out and say you're tossing most of your main software stack to go forward with another). I could certainly be wrong, and if any MySQL fans out there want to help me understand why maybe it will even make it through my shield of bias. -David
Re: Optimistic locking based on timestamps
James, We have run into this same problem on MySQL and ofbiz. We worked around the problem by creating a custom method that got a direction connection from the transaction manager. Then we wrote a custom SELECT for UPDATE on that connection. We needed this functionality because we had multiple application servers hitting the same database and ran into concurrency problems without it. I would like to see the optimistic locking feature enhanced in ofbiz. Maybe we could move away from timestamps and use an increasing unique ID as a replacement. This is definitely a problem with MySQL. We may move away from MySQL if we can find a good replication solution from Postgres. Brett On Thu, Aug 12, 2010 at 2:15 PM, James McGill james.mcg...@ableengineering.com wrote: We are having problems with the optimistic locking. With enable-lock set on an Entity, updates in GenericDAO use a timestamp to do locking. There are a number of issues with this. The biggest one is that it's not a synchronized operation, so there's potential for a race condition within customUpdate, which we are actually seeing in production. I added code to introduce the FOR UPDATE expression when reading the timestamp. This brings up another issue, that the timestamp field in MySQL has resolution only to the second. So even if you don't have contention on the optimistic lock SELECT, you still have to be lucky that your transactions are more than one second apart. I realize this is a fairly difficult problem to address, in general, and that fixing many concurrency issues leads to risks of deadlock. But we are seeing errors in data where the last update wins. Has anyone else had concurrency problems when multiple threads are updating entities? Are there any locking provisions in the Delegator that would allow us to prevent this kind of problem? -- James McGill Phoenix AZ
Re: Using Drools to Help with Rules
I'm working on a non-ofbiz project right now where they are considering replacing the commercial rules engine solution with something like drools. Drools looks like a solid rules engine. They have their own domain specific language (DSL) which makes the rules easy to develop and follow. The also handled nested rules very effectively. I like ECA and SECA as well but I have used them more like database triggers and not a method for implementing complicated rules and workflow, but I could be wrong on this subject. Drools appears to be licensed appropriately for ofbiz. I would be in favor of drools rules engine integration implementation.

My efforts have been how to have a ui that a business person would understand, and generate ECA and SECA to accomplish Thier logic.

I was thinking Drools http://jboss.org/drools/ as its ASL2 so we can have in trunk http://jboss.org/drools/downloads.html and also because of the GUI which could be plugged into OFBiz where ever we need rules - a few cool examples are here http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-introduction/html/ch02.html#d0e166and for the developers or data mining people using Birt etc they can use Eclipse. The uses I can think of right now are: 1. Sending emails to customers - similar to auto responders or triggered emails . 2. Stock reordering - allowing different stock to be treated differently depending on for example how fast its selling or out of which warehouse the most is shipped. 3. Inserting marketing material into parcels - picking different customer segments and targeting them differently. 4. Shipping carrier upgrades / changes depending on either destination or price - like zappos do when they secretly upgrade customers to over night delivery. 5. Refunds to customers if something goes wrong (could automate some of the process) and then if its outside the rules it move to a human for review. The real aim is that I want to move the process of rule changing out of the programers hands and put them into technical business people so that we can make fast changes to the business all done by the business users.

Re: Multiple instances and the JobSandbox
Scott, Thanks for this information. I think the instanceId solves the problem for the Service engine and the JobSandbox table. Do you know if OFBiz has a similar solution for other tables that might have problems with concurrency? We ran into some problems with the order and inventory tables when we ran with multiple application servers. The problem was that ofbiz doesn't appear to support a select for update type of query. This makes it difficult to guarantee that when one application server reads a record (e.g. an inventory record) and then updates it that another application server doesn't read the same record and update it as well. We had to work around this issue by writing custom SQL to do the select for update call. Are there any plans to implement this type of feature in the entity engine? Another approach I have seen implemented called optimistic locking. This is where the entity engine checks the timestamps on updates to make sure the timestamp has not been modified since the record was first read. This type of feature is needed any many ERP like applications. Is there a way in ofbiz to do this now.

We like the above process because it allows us to multi-process the large
batch job.
Here is the problem:
There are over 10K records that are submitted as async service calls in
step
2 above. I'm seeing a transaction time out when the service engine tries
to
process all of these records as it calls an UPDATE JOB_SANDBOX for
job_id=XXX. I believe it is trying to update all 10k of these jobs
individually in a single transaction and times out. The jobs are then
left
in a pending status and never changed but the service engine keeps timing
out.
Here are my questions:
1. Is there a way to increase the transaction time out for the service
engine to update these jobs in the JobSandbox so the service engine
threads
can then process them?
or
2. Is there another way to break these jobs up so the service engine
doesn't have to process 10k jobs in a single transaction.
Note: the above process works very well when the number of records to
process are around 1K.

Service engine timeouts
We are running into a problem with the service engine when trying to run an archiving batch service. Here is how the service runs. 1. We run a service that collects a bunch of records for data warehousing. 2. The data warehouse service calls an async service call to process each individual record. 3. The service engine them starts working on each individual record. We like the above process because it allows us to multi-process the large batch job. Here is the problem: There are over 10K records that are submitted as async service calls in step 2 above.

Need to pass the parameters constructor needs. This tag automatically

Re: Profiling using OFBiz
Neha, I posted this message a few months ago about some profiling probes we wrote to measure method times. They work pretty well and allow you specify what you want to profile (e.g. com.mycode.* or org.ofbiz.entity, etc). I've been meaning to contribute these tools back with instructions on how to use them. I'll open a JIRA issue when I can get this complete. Brett /*/ We have been experimenting with the TPTP tools from eclipse to find performance bottlenecks.

Avoiding the Got a insecure (non-https) form POST warning when running non-secure between Apache and Tomcat
We use Apache web servers to communicate with our OFBiz servers using a combination of mod_jk and mod_proxy. For our mod_proxy configuration, we forward secure requests (https) from Apache to a non-secure port (8080) on Tomcat/OFBiz. Our application is an AJAX/Dojo application that posts normal HTTP requests to the web server, but when we do this we frequently get the following messages: 2010-03-01 13:32:18,890 (http-0.0.0.0-8080-6) [ RequestHandler.java:186:ERROR] Got a insecure (non-https) form POST to a secure (http) request [jsonservice], returning error 2010-03-01 13:32:18,906 (http-0.0.0.0-8080-6) [ RequestHandler.java:204:WARN ] HTTPS is disabled for this site, so we can't tell if this was encrypted or not which means if a form was POSTed and it was not over HTTPS we don't know, but it would be vulnerable to an XSRF and other attacks: Not accepting insecure form data posted to a secure request I understand the reason for the error message and the potential security problems if our Tomcat/OFBiz application server was the front-facing server, but in our environment the Tomcat/OFBiz servers are only accessible via Apache. The request from the user is secure. I don't believe the error causes any problems for us (transaction roll backs, etc), but we would like to eliminate all false error messages in our logs so we can focus on more critical ones. What is the recommendation from the community for avoiding these types of messages when using Apache to Tomcat configuration? Are others working around these issues when they use Apache mod_proxy? Brett
Re: Avoiding the Got a insecure (non-https) form POST warning when running non-secure between Apache and Tomcat
Scott, We don't really have a good reason for turning it off. Here were some of the reasons: - The initial thought was secure connections between web and application servers was not necessary as these are behind the firewall. - We also thought we might be improving performance by not encrypting requests between servers, but we never verified these benefits. - We also use mod_jk and it communicates insecurely using is own AJP protocol. Is your recommendation to turn on security and have mod_proxy communicate directly to port 8443?

I agree with this. Don't assume the network behind the firewall is safe. Enable security wherever and whenever possible.

We use a configuration with Apache on the front end and ofbiz on behind it. We use mod_jk because it has a nice load balancer feature.

Re: Any chance for an upgrade? - help please
Florin, Have you tried using Apache's mod_proxy instead of mod_jk? I'm not surprised that you get faster responses directly from Apache but 2-3 req/sec doesn't sound good for Tomcat either. I'll try this same tool in our configuration and see what we get. For us we configure mod_jk to communicate through the ofbiz AJP port. We have also used mod_proxy which doesn't use AJP and goes directly to Tomcat's http port (8080). I'll run your recommended tool to see what gets better performance.

There are two steps to definining a new entity. 1. First add the entity definition to your entitymodel.xml file which looks you have. 2. Then add the entity to the group file which is usually called entitygroup.xml entity-group group=*org.ofbiz* entity=*TrackUserSource* / If you don't have the entity added to the entitygroup.xml file it won't be created when the server starts up.

Method to tie into the ofbiz shutdown process
We need to perform a clean up operation for some custom caching we are doing with our ofbiz servers. Is there a convenient way to tie into the ofbiz shutdown process for this type of cleanup?

How to change default entity sequencer increment of 10
We are running a mysql 5.x database with 4 applications servers on the same db. We use the GenericDelegator.getNextSeqId() a lot in our code and simple methods.

ApacheCon 2009 Round Table User Feedback
Here are the notes that I took during the ApacheCon 2009 User Round Table. The conference was a success but I believe was less attended than normal. I've been to about 6 ofbiz conferences and this one was the least attended by ofbiz users than others. I attribute this to the current economic situation rather than anything else. Interestingly, a lot of the comments during the round table were similar to ones that we have had in the past. The project continues to make progress but from outsiders it is difficult to measure as some of the new features takes months to see in the end product. There were six people in attendance at the round table. A few had to leave early to catch planes in the afternoon. Of those that attended the round table two were speakers (myself and Ruth). Three of the attendees were service providers trying to better understand the direction of ofbiz and one was a new user that was active in other Apache projects and wanted to know more about ofbiz. Here are the key comments: * Everyone was very interested in the new project that Dave introduced a couple of weeks ago about a specialized application for small business. They wanted to know a lot more about this project and what it would include. There was a lot of excitement about the proposal. I didn't have a lot of details to share so I told them to watch the mailing list for more details on the subject. * Most common complaint. The UI for the out of the box ecommerce application. The general feedback was that from a technical perspective people like ofbiz but it was difficult to convince key business people that ofbiz was right for their organization because of the lacking sizzle in the default application. Non-technical people have a hard time determining how difficult it is to customize the UI and in a quick review will opt for a better looking application because that is all they can really evaluate. The general thought was that the lack of a very nice front end was slowing the adoption for ofbiz * Another suggestion was around content management. The ofbiz CMS is not fully complete with a UI and business logic. The question was asked if it was possible to plugin other CSM packages the the Java Content Repository (JCR). * There were some comments on OpenTaps and what it means to OFBiz. This is always an interesting discussion and I tried to explain the licensing problems with using OpenTaps. The one benefit people had about using OpenTaps is that it has a full CRM application that people can use from the start. OfBiz is more general and requires more customization. * SugarCRM and other similar applications are examples of very large user communities because the application is a complete solution. It is difficult to convince people to use ofbiz because there are pieces that are not complete and require customization. The ability to customize is a benefit for some users but a drawback for others and is a hindrance to wide spread adoption. * Is it possible to break up the components more into separate installable modules. For example, framework versus applications. We discussed how this is currently done but the feedback was to make it easier for people to pick and choose what components to install. * Any plans to integrate a complete rules engine into ofbiz * Version control for release branches. Are they plans to do more frequent releases? The current download of the nightly build is misleading as user think it is a stable release build but it is really just the nightly build from the trunk. * It was stated that OFBiz is a unique apache project as it is focused on business solutions where as most apache projects focus on a single technical problem. How that technology is used in an application is generally irrelevant. OFBiz is different in that it tries to provide a complete solution for businesses and users. The feedback was that in the future it would be nice to attract more end users to the ofbiz apache conference rather than technical people that implement the solution. This was agreed that if there were more complete applications that the user community would grow and all people in the community would benefit. * Another strategy for OFBiz would be to define business best practices and then implement those processes into the applications. This is a difficult task as all businesses are unique but just as ofbiz adopted a common data model there most be common business practices that would benefit all businesses. * Improving the integration of the seleniumXml test framework with the existing ofbiz test framework. Also more examples of tests using the OOTB ofbiz applications would be desired. The above comments are notes that I took during the round table discussion. They are not my own personal opinions but of those of the group. Please feel free to comment on these ideas for the benefit of the community. Overall, the people attending the conference commented that they would like OFBiz to

Re: deploying ofbiz in amazon EC2

Re: Load Balancing in OFbiz
Neha, Here is a configuration we use to do load balancing in ofbiz. Others may do something else. 1. One machine is running an Apache Web server with mod_jk setup to communicate with different instances of ofbiz. The mod_jk is setup to load balance between the different ofbiz instances. Here is a document that helps you get setup: http://tomcat.apache.org/connectors-doc/generic_howto/loadbalancers.html 2. Then we start multiple boxes running ofbiz server - all pointing to the same database. The servers are setup to communicate using mod_jk's AJP protocol. You need to set the jvm-route in the framework/base/config/ofbiz-containers.xml file to insure the load balancer maintains sessions between requests. Here is a snippet of that configuration file. container name=catalina-container class=org.ofbiz.catalina.container.CatalinaContainer !-- static configuration for tomcat -- property name=delegator-name value=default/ property name=use-naming value=false/ property name=debug value=0/ property name=catalina-runtime-home value=runtime/catalina/ property name=apps-context-reloadable value=false/ property name=apps-cross-context value=false/ property name=apps-distributable value=false/ !-- one or more tomcat engines (servers); map to this + host -- property name=default-server value=engine property name=default-host value=0.0.0.0/ *property name=jvm-route value=jvm1/* property name=access-log-pattern . 3.

Re: Load Balancing in OFbiz
1. We run one instance of ofbiz on a separate server but this is because we are running a single application and want to scale by adding more machines. 2. It is easier to use the embedded ofbiz version rather than a standalone tomcat with ofbiz placed as a standard WAR file. From the Apache Web server perspective there isn't any difference. It is talking AJP protocol and can't tell if it is an embedded version of tomcat or standalone. 3. I'm not sure the reason some are running several version of ofbiz on the same machine.

Re: best web framework
Another alternative to RMI is JSON. We use the JSON library that comes with ofbiz to make ofbiz service calls. The library converts the results from the service to a json string. This can be easily parsed by an AJax client or java client. Rmi is ok but a little heavy for our needs. There were also serialization problems when using eclipse for debugging and ant for builds.

In this scenario all app servers are communicating with the database server and coordinate that way. There is no need for communication between the servers except for the Entity Engine distributed cache clearing. If you use a pattern of a webapp server that talks to an app server that talks to a database you have an extra level of remote communications and that will significantly slow down your response times... as well as add the need for LOTS of coding!

You will need to get a copy of the org.ofbiz.service.rmi.socket.zip.CompressionClientSocketFactory and org.ofbiz.service.rmi.socket.zip.CompressionServerSocketFactory from revision 451171 as they are no longer in the trunk due to license issues if you want the example from the wiki to work.

Re: Apache server, Tomcat , SEO and 302 issue
I have had similar requests from clients that use an Apache-Tomcat combination. In this case it was a tomcat struts application but the problem was the same for ofbiz. We were advised that redirecting to tomcat was not recommended for SEO. This is particularly a problem when the whole site it in tomcat and apache is just used as a frontend with a single page. I would be interested in the correct answer for SEO and if anyone has found an optimal solution. Brett On 7/23/07, Jacques Le Roux [EMAIL PROTECTED] wrote: Thanks David, I was asked this by a client who uses a pre-Apache OFBiz version (rev. 4969). He was advised by a SEO company. The problem is that, for the moment, the page indexed is target and not source. My client would prefer to see her domain page (whitout suffix) showing 1st in Google...I have to read deeper in that later. At 1st reading the status has changed either for Google and Yahoo, MNS status is unclear. I wonder if we should not use a modified Tomcat OOTB to handle this. Perhaps there are other ways to do it (Rewrite rules ?) but doing so this problem will vanish forever (just have to reaplied the patch when upgrading Tomcat until they introduce a parameter themself as it's planified in link below). I will let you know as soon as I completly clear on that, this is not a high priority ... Jacques PS : the current target behavior seems correct : http://www.mattcutts.com/blog/seo-advice-url-canonicalization/ (look for 302) De : David Garrett [EMAIL PROTECTED] Jacques, I think relying on SEO information from 2003(ref a.) and Feb 2005(ref b.) in SEO is dangerous. There has been considerable effort by the SEs in the last 1/2 years to improve redirect handling, eg Google Bigdaddy introduction and Yahoo's standard behaviour as given in the links below. http://www.mattcutts.com/blog/seo-advice-discussing-302-redirects/ http://help.yahoo.com/help/us/ysearch/slurp/slurp-11.html I would suggest these are quite authorative pages. This is a VERY subjective area but for me, using your example, I would rather have www.domain.com indexed rather than www.domain.com/control/main. As this is an in domain transfer a 302 temporary redirect (for me) is the correct solution on all counts. I don't completely follow what your change proposes but for me keep the 302. I know this is a very subjective areas and you will get informed and uninformed views to the contrary. The key point to consider is what do you want indexed in the SERPs? My preference is the shorter URL. David G -Original Message- From: Jacques Le Roux [mailto:[EMAIL PROTECTED] Sent: Sunday, 22 July 2007 9:57 PM To: user@ofbiz.apache.org Subject: Apache server, Tomcat , SEO and 302 issue Hi All, Supportin temporary or permanent redirection of matching requests in Tomcat is pious vow from some times now (http://www.jajakarta.org/tomcat/tomcat3.2-4.0/tomcat-4.0b5/sr c/catalina/docs/dev/todo.html see [org.apache.catalina.valves.RedirectValve]) So when in OFBiz, using Apache server as frontal with jkmount, if someone ask for a domain (say http://www.domain.com) this activate a redirection to http://www.domain.com/control/main. An you get a 302 redirect (moved temporarily) and not a 301 (permanent). Not persuaded ? see http://livehttpheaders.mozdev.org/. This makes sense because if it's permanent why use something dynamic ? But the problem with 302 is that it's not good for search engines (this is clearly explained in the 2d link below). So I searched for a solution. I found 2 a.. http://www.sitepoint.com/forums/showthread.php?t=231044 b.. http://blog.spaceprogram.com/2003/06/fixing-tomcat-302-redirec t-issue_18.html I tried the 1st in 1st place but got not the expected result. I guess because the jkmount gives no chance to a 404. I wonder now how OFBiz users deals with this problem before creating my own Tomcat version (actually I will simply replace the concerned class in the corresponding jar) inspired by the 2d solution... Any ideas, advices ? Thanks Jacques PS : I looked also at rewrite rules solutions as in http://www.webmasterworld.com/forum92/2309.htm
Re: How to debug SQL
Change the debug.properties to use verbose. I think this file is on the base/config directory but that is from memory.

Re: Linux install instruction error
Is there a space between ofbiz and chown? It should mean something like add the user ofbiz and then recursively -R change the ownership for the new user ofbiz. I'm not running Fedora but the command should work in any linux install.

Re: Chat Modules
I don't know of any ofbiz modules. You might want to look at jabber as a good open source I.M. technology. I'm not sure what the license is but there are lots of clients to choose from and the security is good. You could possibly integrate this with ofbiz but it depends on what you want to accomplish. If the objective is to control I.M. Communication internally than jabber is a good solution. www.jabber.org Brett On 4/23/07, Scott A [EMAIL PROTECTED] wrote: Hello All, We want to add a chat module to ofbiz for our employees to be able to communicate with each other when they are online.

Does anyone know of any modules out there that may be consistent with the Apache license that we could work on and give back to the community? Any pointers from the senior guys here?

Re: Quickbooks OfBi
I worked on a contract where we integrated ofbiz orders with quickbooks. The project never finished but we did discover that using a 3rd party library call QODBC was much faster than the intuit web services interface. The difficult part was mapping all the data values between the two systems. And if you need to do updates in QB you have to store record IDs on the ofbiz side.
